Answer:
Question 39: False
Question 43: True
Step-by-step explanation:
<u>Question 39</u>
|-4| is a solution of x ≤ 4
|-4| ⇒ This mean the absolute value of 4. The sign s are neglected.
So, |-4| is not a solution of x ≤ 4.
<u>Question 43</u>
The point (5, -1) is a solution of the equation: y = 2x − 11.
To prove this we are to substitute the point (5, -1) in the equation y = 2x − 11.
y = -1 and x = 5
y = 2x − 11 ⇒ -1 = 2(5) -11
-1 = 10 - 11
-1 = -1
Answer:
Step-by-step explanation:
We have the following equation:
We can use the quadratic formula given by:
Where:
And replacing we got:
You subtract 135 from 260
260-135=125 pounds
Therefore Heather weighs 125 pounds

Answer:
see explanation
Step-by-step explanation:
Given the translation rule
(x, y ) → (x - 3, y - 2 )
This means subtract 3 from the original x- coordinates and subtract 2 from the original y- coordinates, that is
A(5, 3 ) → A'(5 - 3, 3 - 2 ) → A'(2, 1 )
J(5, - 1 ) → J'(5 - 3, - 1 - 2 ) → J'(2, - 3 )
X(1, - 1 ) → X'(1 - 3, - 1 - 2 ) → X'(- 2, - 3 )
Z(2, 4 ) → Z'(2 - 3, 4 - 2 ) → Z'(- 1, 2 )
