y - 2x = -3
m =
C =
Please help
Answer:
m = 2, c = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y - 2x = - 3 ( add 2x to both sides )
y = 2x - 3 ← in slope- intercept form
with slope m = 2 and y- intercept c = - 3

Answer:
y=-4
Step-by-step explanation:
Use the interactive graph below to sketch a graph of y=-3 • 2^x-4
The exponential function y = -3× 2⁽ˣ⁻⁴⁾ shows an exponential decay in the graph.
What is Exponential Function?An exponential graph is a curve that represents an exponential function. An exponential graph is a curve that has a horizontal asymptote and it either has an increasing slope or a decreasing slope. The graphs of exponential functions are nonlinear because their slopes are always changing, like curves, not straight lines
In the function given, we have that
y = -3× 2⁽ˣ⁻⁴⁾
This can be represented on a graph which shows an exponential decay of the function.

Kathy earns $445 a week for 40 hours of work and $25 an hour for each hour over 40. How many hours did Kathy work if she earned $570 in one week?
Answer:
45 hours
Step-by-step explanation:
you subtract the standard price from the increased price which is 570.
you get 125 and divide by the amount of money added per hour then you get five
add that 5 to the standard hours per week
40 + 5=45

Find the center and radius of this circle by converting it to (x-h)2 + (y-k)2 =r2
Answer:
r=5 O(1;-12)
Step-by-step explanation:
x² + y² -2x + 24y +120 = 0
⇒ x²-2x+1+ y²+ 24y+144-145+120 = 0
⇒ (x-1)²+ (y+12)²=25 and (x-h)² + (y-k)² =r²
so, h=1 k=-12 r=√25=5
center is O(h;k) O(1;-12)

Look at the expression below: 7 * 11 * 13. How many factors does the product of the expression have?
Answer:
3 factors.
Step-by-step explanation:
When we have a product of some numbers A, B and C
A*B*C
(here I used 3, but the number does not matter, is just for the example)
To find the number of factors of the product, we first need to find the number of factors for each one of the numbers that is being multiplicated.
Here you need to remember that every integer number can be written as a product of prime numbers.
For example, 15 can be written as:
15 = 2*3*5
So the number 15 has 3 factors.
In the case of prime numbers, like 7, we have:
7 = 7
So 7 has only one factor in its decomposition.
In our case, our numbers are:
7, 11, and 13.
We can see that the 3 numbers are prime numbers.
Then each number has only one factor in its decomposition.
Then we have 3 factors in the multiplication, it is:
7*11*13
If an event is unlikely to occur, its probability will be a negative number.
A) true
B) false
Answer
False
Step-by-step explanation:
The max number is 1 and so the unlikelier the number, the less value the number will be.
For example: The likelyhood of fliping a coin and landing on heads: 0.5

Find the area of the shaded region.
Give the exact answer.
60°
0
6
A =
Answer:
25.35
Step-by-step explanation:
Area of the shaded portion = Area of semicircle - Area of the right triangle
Area of semicircle = πr²/2
Area of semicircle = 3.14(6)²/2
Area of semicircle = 3.14 * 18
Area of semicircle = 56.52
Area of triangle = 1/2 * base * height
Get the height using the SOH CAH TOA identity
sin 60 = H/12
H = 12sin60
H = 12(0.8660)
H = 10.39
Get the base
12² = b²+10.39²
144 = b²+108
b² = 144 - 108
b² = 36
b = 6
Area of triangle = 1/2 * 6 * 10.39
Area of triangle = 3 * 10.39
Area of triangle = 31.17
Area of shaded portion = 56.52 - 31.17
Area of shaded portion = 25.35
1. Cole bought a snowmobile for $600. He spent $430 on parts to fix it, then sold it for
$1,100.
a. What was his profit?
b. If he spent 8 hours fixing it, how much money did he make per hour?
Answer:
70$ profit
8.75 per hour
Step-by-step explanation:
Ole's profit was $70 and Ole made $8.75 per hour fixing and selling the snowmobile.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
To find the profit, we need to subtract the total cost of buying and fixing the snowmobile from the amount he sold it for:
Profit = Selling Price - Total Cost
Total Cost = Purchase Price + Cost of Parts
Total Cost = $600 + $430 = $1030
Profit = $1100 - $1030 = $70
Therefore, Ole's profit was $70.
b. To find the money Ole made per hour, we need to know how much time he spent fixing the snowmobile.
He spent 8 hours fixing it, so his hourly rate would be:
Hourly Rate = Profit / Time
Hourly Rate = $70 / 8 hours
Hourly Rate = $8.75 per hour
Therefore, Ole made $8.75 per hour fixing and selling the snowmobile.

Answer:
13
Step-by-step explanation:
It would have to be 13, because if you look at the top of the shape, you see the little 45 degrees. You can also see the 90 degrees right angle. Triangles no matter what add up to 180 degrees.
(a is the unknown angle in the bottom right)
90+45+a=180
45+a=90
a=45
now that we have that , we know that it has to be symmetrical.
so it can only be 13

Given the function f(x)=x^2-8x+13f(x)=x, determine the average rate of change of the function over the interval −1≤x≤6.
Given:
Consider the given function is:
[tex]f(x)=x^2-8x+13[/tex]
To find:
The average rate of change of the function over the interval [tex]-1\leq x\leq 6[/tex].
Solution:
The average rate of change of the function f(x) over the interval [a,b] is:
[tex]m=\dfrac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]
We have,
[tex]f(x)=x^2-8x+13[/tex]
At [tex]x=-1[/tex],
[tex]f(-1)=(-1)^2-8(-1)+13[/tex]
[tex]f(-1)=1+8+13[/tex]
[tex]f(-1)=22[/tex]
At [tex]x=6[/tex],
[tex]f(6)=(6)^2-8(6)+13[/tex]
[tex]f(6)=36-48+13[/tex]
[tex]f(6)=1[/tex]
Now, the average rate of change of the function f(x) over the interval [tex]-1\leq x\leq 6[/tex] is:
[tex]m=\dfrac{f(6)-f(-1)}{6-(-1)}[/tex]
[tex]m=\dfrac{1-22}{7}[/tex]
[tex]m=\dfrac{-21}{7}[/tex]
[tex]m=-3[/tex]
Therefore, the average rate of change of the function f(x) over the interval [tex]-1\leq x\leq 6[/tex] is -3.

Suppose f(x)=x^2 what is the graph of g(x)=f(2x)
Answer:
The graph is attached.
Step-by-step explanation:
Since g(x) = f(2x), this means we substitute 2x in place of x for f(x):
g(x) = f(2x) = (2x)² = 4x²
Graphing this, the parabola is not moved from the parent graph f(x) = x², but the graph is compressed horizontally by a factor of 4.
