Answer:
-10
Step-by-step explanation:
first you need to solve the first equation
3x + 7 = 10
subtract 7 from both sides
3x + 7 - 7 = 10 - 7
3x = 3
divide both sides by 3
3x/3 = 3/3
x = 1
now substitute x in the second equation.
-2x - 8
-2(1) - 8
-2 - 8
-10
Answer:
- 10
Step-by-step explanation:
Given
3x + 7 = 10 ( subtract 7 from both sides )
3x = 3 ( divide both sides by 3 )
x = 1
Thus
- 2x - 8 = - 2(1) - 8 = - 2 - 8 = - 10
Create an equation of a line that crosses the y-axis at the origin and has a slope of 1/2
Answer:
since the line goes through the origin you dont need a y intercept.
y= x/2
or y= 1/2 x
Solve for x:
logx=3log2
(I forgot how to do simple logarithmic equations lol)

Write an integer that represents the situation. Do not type any units, labels, or spaces or your answer will be scored as incorrect. Death Valley California is the lowest land in the United States, and portion of it lies two hundred eighty two feet below sea level.
Answer:
-282
Step-by-step explanation:
Given
[tex]Position = 282ft[/tex]
Required
Represent this with an integer.
Since, it is below the se level.
The integer is:
[tex]Integer = Sea\ Level - Position[/tex]
Where:
[tex]Sea\ Level=0[/tex]
[tex]Integer = Sea\ Level - Position[/tex]
[tex]Integer = 0 - 282[/tex]
[tex]Integer = -282[/tex]

You play basketball At your schools indoor stadium. You have two payment options. Option A is to buy a membership card for $20 and pay $2 each time you go to the gym, t. Option B is to pay $4 each time you go. After how many trips to the gym will the cost be the same?
Answer:
10 trips
Step-by-step explanation:
Let the number of trips to the gym be represented by t
Option A is to buy a membership card for $20 and pay $2 each time you go to the gym.
$20 + $2× t
20 + 2t
Option B is to pay $4 each time you go.
$4 × t
= 4t
After how many trips to the gym will the cost be the same?
Option A = Option B
20 + 2t = 4t
Collect like terms
20 = 4t - 2t
20 = 2t
t = 20/2
t = 10 trips.
After 10 trips, the gym cost will be the same.

5^3 / 5^-3 oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
Answer: 5^3 / 5^-3 = 5^6 = 15,625
Step-by-step explanation:
Ok, you may find useful for problems like this the next two relations:
[tex]x^a*x^b = x^{a + b}[/tex]
[tex]x^a/x^b = x^{a - b}[/tex]
Now we have the equation:
5^3/5^-3
We have a quotient, then we need to use the second relationship, where:
x = 5
a = 3
b = -3
5^3/5^-3 = 5^(3 - (-3)) = 5^(3 + 3) = 5^6 = 15,625

3(5x+1)-3x=2-3(3x+1)
Answer:
x = − 4 \21
Step-by-step explanation:
Answer:
x= [tex]-\frac{4}{21}[/tex]
Step-by-step explanation:
Step 1- Distribute into the parenthesis.
(3)5x+(3)1-3x=2+(-3)3x+(-3)1
Step 2- Multiply.
15x+3-3x= 2-9x-3
Step 3- Add common variables.
(15x-3x)+3=(2-3)-9x
12x+3=-1-9x
Step 4- Add 9x to both sides.
12x+3= -1-9x
+9x +9x
21x+3= -1
Step 5- Subtract 3 to both sides.
21x+3= -1
-3 -3
21x= -4
Step 6- Divide both sides by 21.
21x= -4
21 21
x= [tex]-\frac{4}{21}[/tex]

y = 5x + 2 and y = 5x – 1 parallel, perpendicular, or neither
Answer:
Parallel
Step-by-step explanation:
Parallel lines have the same slope, in this equation it is a slope of 5.
The given lines are parallel in nature.
What is slope?Numerical measure of a line's inclination relative to the horizontal.
Equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation.
Given:
y = 5x + 2 and y = 5x – 1
The slope for line 1 is 5.
and, the slope for line 2 is 5.
For, perpendicular line the slope of both lines are negative inverse relation.
But here the slope of both line are same which have parallel nature.
Hence, both lines are parallel in nature.

sum n=3 ^ infty (2n+5)
find the series shown
=====================================================
Explanation:
We're adding terms in the form (2n+5)
The first term is when n = 3, so
2n+5 = 2*3+5 = 6+5 = 11
The next term is when n = 4, so
2n+5 = 2*4+5 = 8+5 = 13
The next term is when n = 5, so
2n+5 = 2*5+5 = 10+5 = 15
And so on
This means,
[tex]\displaystyle \sum_{n=3}^{\infty} (2n+5) = 11+13+15+17+\ldots[/tex]
which matches with choice C. The three dots indicates the pattern goes on forever.
-------------------
Choice B does not have these dots, so that's why choice B is not the answer. If we replaced the infinity symbol with 7, then choice B would be the answer.
I.e,
[tex]\displaystyle \sum_{n=3}^{7} (2n+5) = 11+13+15+17+19[/tex]

The solution is, The correct option is (C).
The graph of G(x) is the graph of F(x) shifted 5 units up.
What is graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
here, we have,
Given:
G(x) = F(x) + 5
As, the transformation takes place so there is a positive five.
The value of the function for a given x is the vertical position of the point on the graph.
Adding 5 to the function value shifts the graph up 5 units.
Hence, The graph of G(x) is the graph of F(x) shifted 5 units up.
