Which equation represents the line that passes through the point (−2,2) and is parallel to y - 8= 12x ?
Answers
Answer:
y=12x+26
Step-by-step explanation:
We need an equation that passes through (-2,2) and is parallel to y-8=12x.
For this problem, we are going to use point slope form. Point slope form is written like this: [tex]y-y_{1} =m(x-x_{1})[/tex]. Parallel lines on graphs also have the same slope and different y-intercepts. Let's start plugging our known values. We will start with the slope. We know that the slope is 12, so m=12.
[tex]y-y_{1}=12(x-x_{1})[/tex].
We also know that [tex]y_{1} =2, x_{1}=-2[/tex]. Now let's solve
[tex]y-2=12(x+2)\\y-2=12x+24\\y=12x+26[/tex]
Elevation represents distance from sea level. Positive numbers represent elevations that are above sea level and negative numbers represent elevations that are below sea level.

On which day did the hiker travel the furthest distance.
A. Monday
B. Tuesday
C. Wednesday
D. Thursday
Answers
Answer:
The answer is C i got it right i am not lieing
Step-by-step explanation:
On Wednesday the hiker had the greatest elevation of 8.74 km.
What is an absolute value function?We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.
In piecewise terms | x | = x for x ≥ 0 and | x | = - x for x < 0.
Given, Elevation represents the distance from sea level.
Positive numbers represent elevations that are above sea level and negative numbers represent elevations that are below sea level.
We know distance is always positive so if we look through the table on Wednesday the hiker has hiked - 8.75 km,
Now modulus of - 8.75 is | - 8.75 | = 8.75, so on Wednesday the hiker has the greatest distance covered.

Answers
Answer:
true
Step-by-step explanation:
took the quiz
The polynomial f(x) = 1 – 2x - 3x⁴ as x → infinity, f(x) → -infinity is true because the leading term is negative.
What is polynomial?Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.
[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]
We have a polynomial:
f(x) = 1 – 2x - 3x⁴
or
f(x) = - 3x⁴ - 2x + 1
As we increase the value of x the value of f(x) decreases because the leading term is negative.
Leading term = -3
Thus, the polynomial f(x) = 1 – 2x - 3x⁴ as x → infinity, f(x) → -infinity is true because the leading term is negative.

Tomas is making trail mix using granola and walnuts. He can spend a total of $12 on the ingredients. He buys 3 pounds of granola that costs $2.00 per pound. The walnuts cost $6 per pound. He uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. He solves the equation for y, the number of pounds of walnuts he can buy. Which is the first error that Tomas made? Tomas substituted the 3 for x when he should have substituted 6 for x. Tomas added 6 to both sides of the equation instead of subtracting 6. Tomas should have written the equation as . Tomas substituted 3 for x when he should have substituted 3 for y.
Answers
Correct question is;
Tomas is making trail mix using granola and walnuts. he can spend a total of $12 on the ingredients. he buys 3 pounds of granola that costs $2.00 per pound. The walnuts cost $6 per pound. He uses the equation 2x + 6y = 12 to represent the total cost,
Where x represents the number of pounds of granola and y represents the number of pounds of walnuts. He solves the equation for y, the number of pounds of walnuts he can buy.
2x + 6y = 12
2(3) + 6y = 12
6 + 6y + 6 = 12 + 6
6y = 18
y = 3
which is the first error that tomas made?
A) tomas substituted the 3 for x when he should have substituted 6 for x.
B) tomas added 6 to both sides of the equation instead of subtracting 6.
C) tomas should have written the equation as 3x + 6y = 12.
D) tomas substituted 3 for x when he should have substituted 3 for y.
Answer:
Option B: tomas added 6 to both sides of the equation instead of subtracting 6.
Step-by-step explanation:
We are told that; x represents the number of pounds of granola while y represents the number of pounds of walnuts.
Now, we are told that He can spend a total of $12 on the ingredients. Also that he buys 3 pounds of granola that costs $2.00 per pound while the walnuts cost $6 per pound.
Thus;
2x + 6y = 12
He buys 3 pounds of granola. Thus;
2(3) + 6y = 12
6 + 6y = 12
The next step here is to subtract 6 from both sides but Tomas added 6 to both sides instead.
Thus, option B is the correct answer.

The distance an electric car can travel on one full charge depends on the speed of the car. The table shows the approximate distances a certain model of electric car can travel on one full charge
when moving at various constant speeds.
The speed and the corresponding distance form an arithmetic sequence, where the speed represents the number of the term and the corresponding distance represents the value of the term.
What is the distance, in miles, that the car can travel on one full charge when moving at a constant speed of 75 miles per hour (mph)?
A) 220
B250
С270
D290
Answers
Answer:
Distance covered by the car = 220 miles
Step-by-step explanation:
Speed (mph) (s) Distance (miles) (d) Difference in distances
45 400 -
50 370 400 - 370 = 30
55 340 370 - 340 = 30
60 310 340 - 310 = 30
65 280 310 - 280 = 30
Since differences between each successive term of the distances are common,
Therefore, table represents a linear function.
Let the equation representing the relation between the speed and distance is,
d = ms + c
Where m = slope of the line
And c = y-intercept
For a point (45, 400) lying on the line,
400 = 45m + c ----- (1)
Similarly, for a point (60, 310),
310 = 60m + c -------(2)
Equation (1) - equation (2)
400 - 310 = 45m - 60m
90 = -15m
m = -6
By substituting m = -6 in equation (1),
400 = 45(-6) + c
c = 400 + 270
c = 670
Therefore, equation will be,
s = -6d + 670
Now we have to calculate the distance covered by the car when moving with a constant speed of 75 mph,
d = -6(75) + 670
d = 670 - 450
d = 220 miles
Roger wants to make a deposit into his savings account. He is depositing 2 checks, one for 95.62 and the other for $432.50. He would like to receive $60.00 in cash after the deposit. Calculate the amount that he will be depositing into his savings account.
Answers
Answer:
$468.12
Step-by-step explanation:
Given that:
Amount to deposit:
Check 1: = $95.62
Check 2 = $432.50
Amount he'll like to receive or withdraw = $60
Total amount he'll be depositing :
Check 1 + Check 2 - withdrawal
$95.62 + $432.50 - $60
= $468.12
Whitney sells cars at a local dealership. She receives a monthly salary of $904.00 and a $159.00 commission on each car she sells. If Whitney receives her commission check at the end of the month along with her salary check, which of the following equations can be used to determine her total pay for the month?
(Let x represent the number of policies sold and y represent the total amount of pay for the month.)
A.
y = 904x + 159
B.
y = 159x
C.
y = 159x + 904
D.
y = 15.9x + 904
Answers
Answer:
The equation can be used to determine her total pay for the month is
y = 159x + 904 ⇒ C
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope ⇒ rate of changeb is the y-intercept ⇒ initial amount∵ Whitney receives a monthly salary of $904.00
→ It is a fixed amount
∴ The initial amount of her salary is $904.00
∴ b = 904
∵ She takes a $159.00 commission on each car she sells
→ That means the commission is changing with the number of cars sold
∴ The commission is the rat of change
∴ m = 159
→ Substitute the values of m, b in the form of the equation above
∴ y = 159x + 904
The equations can be used to determine her total pay for the month is
y = 159x + 904

Tommy runs a lemonade stand to raise money for Baker Children's Hospital. Last weekend, he made 8 quarts of lemonade to sell. Saturday was rainy, so he only sold 6 cups. The weather was better on Sunday, so he sold 18 cups. How many quarts of lemonade does he have left?
Answers
Answer:
2 quarts
Step-by-step explanation:
In order to solve this problem we first need to calculate the total amount of lemonade, Tommy made in Cups. Since 1 quart holds 4 cups we simply multiply the 8 quarts that Tommy made by 4 like so...
8 * 4 = 32 cups of Lemonade
Now that we know that Tommy made a total of 32 cups of lemonade we can subtract the number of cups he sold each day from the total.
32 - 6 - 18 = 8 cups
Finally, we see that after selling 6 cups on Saturday and 18 cups on Sunday he has 8 cups left. Now we simply divide this by 4 to turn the cups back into quarts
8 / 4 = 2 quarts
Answer:
2 quarts
