Answer:
0=0
Step-by-step explanation:
(x+6)(x-5) = x^2 + - 30
Step 1: Simplify both sides of the equation.
x^2 + x-30 = x^2 + x-30
Step 2: Subtract x^2 from both sides.
x^2 + x - 30 - x^2 = x^2 + x - 30 - x^2
x-30=x-30
Step 3: Subtract x from both sides.
x-30-x=30-x
-30 = - 30
step 4: Add 30 to both sides.
-30+ 30 = -30 + 30
0=0
Okay so I'm guessing that they are two different formulas the f(x)= 3x and the f(x)= -5x-2. If that's is true then you would just have to plug in -2 to the x's. So then it would be f(x)= 3(-2) which if you solve it would give you f(x)= -6 and for the second one it would be f(x)= -5(-2)-2 so then you would solve for it and get f(x)= 8.
Answer:
c) 72
Step-by-step explanation:
- the function f(x)=7x+2 represents the number of cars that drive by in x minutes
- x = 10
- f(10) = 7×10+2 = 70+2 = 72
You did not attach any
picture to solve this problem. We cannot calculate for the value W’X’ without
the correct illustrations. However, I think I found the correct one (see
attached), please attach it next time.
So the first thing we have to
do is to calculate for the dilation factor. Taking point G as the reference
point, we can see that the distance of point G from rectangle W’X’Y’Z’ is 1.5
while the distance from rectangle WXYZ is (1.5 + 7.5), therefore the dilation factor
to use is:
dilation factor = 1.5 / (1.5
+ 7.5) = 1.5 / 9 = 1/6
Since WX has an initial
measure of 3 units, therefore the measure of W’X’ is:
W’X’ = 3 units * (1/6) = 0.5
units

Answer:
Domain: (−∞,∞),{x|x∈R}
Range: (−∞,∞),{y|y∈R}
Step-by-step explanation:
Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.
Domain: (−∞,∞),{x|x∈R}
Range: (−∞,∞),{y|y∈R}
