Answer:
For radio = $40.43
Television = $444.73
Player = $364.73
Step-by-step explanation:
The computation of the each device cost is shown below:
let us assume the following things
radio be x
television x + 10x
player x + 10x - $80
Now the equation is
x + x + 10x + x + 10x - $80 = $850
3x + 20x - $80 = $850
23x = $930
x = $40.43
For radio = $40.43
Television = $40.43 + 10(40.43)
= $40.43 + $404.3
= $444.73
and, the player would be
= $444.73 - $80
= $364.73
Answer:
f(-4)= 24
Step-by-step explanation:
-4(-4)+8 We need to multiply -4 and -4 and a negative times a negative is a positive.
16+8 Now it's easy math and we just add them
This gives us 24.
2t^2+1
Subtract t^2 from 3t^2 you get 2t^2
which is 2t^2+1 answer
Answer:
The length of the frame is 17
Step-by-step explanation:
The computation of the length of the frame is shown below:
As we know that
The perimeter of a rectangle is
= 2 (length + width)
where,
let us assume the width be x
So, the length is x - 6
And, the perimeter is 80 yards
So, now put these values to the above formula
80 yards = 2 (x - 6+ x)
80 yards = 2 (2x - 6)
80 yards = 4x - 12
92 = 4x
x = 23
So, the length of the frame is
= 23 - 6
= 17
It’s the last answer because the slope equals 1 which basically equals just x. And the y intercept is -5
