The additive inverse of -7 is 7, the additive inverse of a number is when added to any number equals 0. So the additive inverse of -14=14 and 7=-7.
Answer: x= 1/2
4x+8=10 1. Subtract 8 from both sides
-8 -8
——————
4x=2 2. Divide each side by 4
/4 /4
—————— 3. Simplify fraction
x=1/2
Answer:
Each side of the L-shaped sidewalk is 126 m and 32m respectively.
Step-by-step explanation:
Given:
Total length of the sidewalk = 158 meters
Cutting across the lawn the distance = 130 meters
The L-shaped lawn will be treated as a right angled triangle.
So the 130 m distance is the hypotenuse here.
Let one side of the L-shaped lawn be 'x' meter so the another side will be (158-x) meters.
Applying Pythagoras formula.

So,
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒
Applying quadratic formula;
Quadratic formula :
where a=1 and b=-158 and c=4032
So the value of x= 126 and 32.
The length of each side of the sidewalk is 'x'= 126 m and '(158-x)'='(158-126)'=32 m
Answer:
Hello, hope this will help:)
The answer is C) the slope is 2.50 and the y-intercept is 9, assuming the question refers to the parameters of his monthly cost.
His cost function could be described as y= 2.5x + 9, where x is the number of comic books he purchases. If he buys no comic books, he still has to pay the $9 membership fee.
