How can you look at the equation of two lines and determine if they will be perpendicular?
Answer:
By looking at the slope
Step-by-step explanation:
Let's use these equation: y = 2x + 3 and y = 2x - 9
You know that those two equations are parallel because the slope is the exact same!
But, if we rewrite those equations to: y = -2x + 3 and y = 1/2x - 9
You can now see that the equations are perpendicular because the slopes are Opposite Reciprocal. The slopes have opposite signs (pos./neg.) and are reciprocal numbers: 2 = 1/2
Use a translation rule to describe the translation that is 3 units to the right and 6 units down
1. (x, y) --> (x + 3, y + 6)
2. (x, y) --> (x + 3, y - 6)
3. (x, y) --> (x - 3, y - 6)
4. (x, y) --> (x - 3, y + 6)
Step-by-step explanation:
Translation that is 3 units to the right and 6 units down translate the point (x,y) into the point (x+3,y-6). Example: if you translate the origin (0,0) 6 units to the left and 5 units up, then you obtain point (-6,5)

Step-by-step explanation:
A water truck is filling a swimming pool. The equation that represents this relationship is y = 19.75x where y is the number of gallons of water in the pool and x is the number of minutes the truck has been filling the pool. Choose True or False for each statement.
Answer:
The answer is TrueStep-by-step explanation:
Given the expression
y = 19.75x------------------1
and y is the number of gallons
we know that
rate= quantity/time
quantity= rate*time-----------2
comparing the two equations
we can see that
the rate is 19.75 gallons/minutes
and the time is x
therefore x is the number of minutes taken
find the value of x

Item 3 Eleven Fahrenheit temperatures are shown on a map during a weather report. When the temperatures are ordered from least to greatest, the middle temperature is below 0°F. Do you know exactly how many of the temperatures are represented by negative numbers? Explain
Answer:
5 of the temperatures are represented by negative numbers
Step-by-step explanation:
To calculate the median, we need to order from the lowest to the highest and select the middle number.
For 0 to be the middle number, it means that there are equal positive numbers as well as equal negative numbers.
Hence, we have 5 numbers to the left of zero and 5 numbers to the right of zero
Hence, we can say that 5 of the temperatures are represented by negative numbers
Richard and Teo have a combined age of 39. Richard is 6 years older than twice Teo's age. How old are Richard and Teo?
Answer:
Teo is 11 years old
Richard is 28 years old
Step-by-step explanation
t=teo
Richard=2t+6
2t+6+t=39
3t=33
t=11
2*11+6=28
Answer: Richard is 28 and Theo is 11
Step-by-step explanation:
Because if theo was 11, 11 x 2 = 22 and since richard is 6 years older than double theos age, 22 + 6 = 28, so the combination of theos and richards age is 11+28 =39

A group of five friends goes to the state fair. Each friend pays the entrance fee and buys one booklet of ride tickets and a meal ticket. The entrance fee is d dollars. A booklet of ride tickets costs 2.5 times the entrance fee. A meal ticket costs $4 less than the entrance fee. Which part of the expression represents the total amount each friend pays?
A) d+2.5d+d
B) d+2.5d+d-4
C) 2.5d
D) 5
Answer:
for the second part its d+2.5d+d-4
Step-by-step explanation:
The part of the expression represents the total amount each friend pays is d+2.5d+d-4.
What is Expression?An expression is combination of variables, numbers and operators.
Each friend pays for the entrance fee, a booklet of ride tickets, and a meal ticket.
The entrance fee costs d dollars.
A booklet of ride tickets costs 2.5 times the entrance fee, which is 2.5d dollars.
A meal ticket costs $4 less than the entrance fee, which is (d - 4) dollars.
Therefore, the total amount each friend pays is:
d + 2.5d + (d - 4)
Simplifying the expression, we get:
4.5d - 4
Hence, d+2.5d+d-4 is the part of the expression represents the total amount each friend pays.

Henry incorrectly said the rate 1/3 pound / 1/9 gallon can be written as the unit rate 1/27 pound per gallon. What is the correct unit rate? What was Henry´s likely error?
Answer:
The unit rate is 3 pounds per gallon.
Henry's likely error could have been that he multiplied instead of dividing.
Step-by-step explanation:
Given the rate 1/3 pound / 1/9 gallon, this can be written in the unit rate by dividing 1/3 pound by 1/9 gallon. First, we will evaluate 1/3 divided by 1/9 and the unit will be in pound per gallon.
1/3 divided by 1/9 can be written as
[tex]\frac{1}{3} \div \frac{1}{9}[/tex]
This then becomes
[tex]\frac{1}{3} \times \frac{9}{1}[/tex]
[tex]\frac{1}{3} \times \frac{9}{1} = \frac{9}{3} = 3[/tex]
Hence, the unit rate is 3 pounds per gallon.
Henry's likely error could have been that he multiplied instead of dividing. That is, he multiplied 1/3 by 1/9, Such that he gets
[tex]\frac{1}{3} \times \frac{1}{9}[/tex]
[tex]\frac{1}{3} \times \frac{1}{9} = \frac{1}{27}[/tex]
Hence, the 1/27 pound per gallon he got.

Step-by-step explanation:
When a solar flare occurs, how long does it take before a scientist sees it? (The Earth-Sun distance is 1.5*10^11m and the speed of light is approximately 3*10^8 m/s.
Answer:
It will take 500 seconds before the scientist sees the solar flare
Step-by-step explanation:
From the question, the Earth-Sun distance is 1.5×10¹¹ m and the speed of light is approximately 3×10⁸ m/s.
Now, we are to determine how long it will take before a scientist sees a solar flare after it has occurred. That is, we are to determine time.
From the formula
Speed = Distance / Time
Time = Distance / Speed
From the question,
Distance = 1.5×10¹¹ m
and speed = 3×10⁸ m/s
Therefore,
Time = 1.5×10¹¹ m / 3×10⁸ m/s
∴ Time = 0.5 × 10³ s
Time = 500 s
Hence, it will take 500 seconds before the scientist sees the solar flare.

Answer:
the third answer
Step-by-step explanation:
f(x) = 3x + 1 works because...
x = 1
y = 4
f(x) = 3x + 1
f(1) = 3x + 1
y = 3x + 1
4 = 3(1) + 1
4 = 3 + 1
4 = 4
AND
x = 2
y = 7
f(x) = 3x + 1
f(2) = 3x + 1
y = 3x + 1
7 = 3(2) + 1
7 = 6 + 1
7 = 7
