D because perpendicular lines intersect at a right angle and D is the only shape with right angles.
Answer:
Yes, if x < -1
Step-by-step explanation:
Is x + 5 less than 4?
x + 5 < 4
x < 4 - 5
x < -1
Yes, if x < -1
Answer:
The new price is 41.60
Step-by-step explanation:
First find the discount
52 * 20%
52 * .2
10.4
Subtract this from 52
52 - 10.4
41.6
The new price is 41.60
The correct answer is 'Equation F can be written as 2d + 1 = 3d + 7'. In order to find the answer to a system of equations, the two equations must be set equal to each other. For instance, if we had the equations x = y + 1 and x = 3y - 1, we would set the two equations equal to one another to find the answer.
x = y + 1
x = 3y - 1
y + 1 = 3y - 1
1 = 2y - 1
2 = 2y
1 = y
x = y + 1
x = 1 + 1
<span>x = 2
We can use this to solve the set of equations above.
</span><span>2d + 1 = 3d + 7
</span>1 = d + 7
-6 = d
c = 2d + 1
c = 2(-6) + 1
c = -12 + 1
c = -11
Hope this helps!
Solution:
Given data: 
and 
To find F(x) + G(x):
Adding two functions which gives another function.
Substitute F(x) and G(x), we get
Hence,
