Here we must see which information about the graph of a linear relationship is given. The information given is just the y-intercept and a point that is not an intercept, thus the correct option is E.
<h3>
Linear relationships:</h3>
So we define a general linear relationship as:
y = a*x + b
Where a is the slope and b is the y-intercept.
In this problem we know that:
- Originally, the sheet of ice is 2 meters thick.
- The thickness decays at a constant rate
- After 3 weeks, the thickness is 1.25 meters.
The first point gives us the y-intercept (the thickness at week 0), the second one gives us the fact that the relationship is linear, and the third one is just a point on the line (that can be used to get the slope.)
So the information given is just the y-intercept and a point that is not an intercept, thus the correct option is E.

Answer:
Use the equation h(t)=-b/2a to find the x value of the vertex, then plug that back into the equation to find the y value which is your height.
Step-by-step explanation:
You can also complete the square to get the equation into vertex form, then your height is the y value of your vertex. Remember the maximum height is always at the vertex of an inverted parabola.
Answer:

Step-by-step explanation:
When x = 5 then x > 3 , thus
f(5) = - 1
When x = 3 then x ≤ 3 , thus
f(3) = - 2x + 2 = - 2(3) + 2 = - 6 + 2 = - 4
-----------------------------------------------------------
When x = - 4 then - 4 ≤ x ≤ 1 , thus
f(- 4) = 2
When x = 3 then x > 1 , thus
f(3) = - x + 1 = - 3 + 1 = - 2
Answer:
the answer is 12
Step-by-step explanation:
you basically have to divide 8 by 2/3 then you would get 12
- 8/1 / 2/3
- kcf
- 8/1 x 3/2= 24/2
- 24 divided by 2 = 12
Answer:
e. 2x - 7y = 31.
Step-by-step explanation:
If you want a line parallel to the equation, the line must have the same slope.
2x - 7y = 9
-7y = -2x + 9
y = 2/7x - 9/7
You are looking for a line where the slope is 2/7.
a. Slope is 7/2.
b. Slope is -7/2.
c. Slope is 7/2.
d. Slope is...
y + 2 = 3/4x + 3
y = 3/4x + 1
Slope is 3/4.
e. Slope is -2/-7, which is 2/7. Just make sure to check whether it passes through (5, -3) by substituting those points into the equation.
2 * 5 - 7 * -3 = 31
10 --21 = 31
10 + 21 = 31
And there's your answer: e.
Hope this helps!
