X=number of true or false
y=number of multiplule choice

total questions is 20
x+y=20

total poits is 100
3x+11y=100

eliminate x's

multiply first equaiton by -3 and add to 2nd

-3x-3y=-60
<u>3x+11y=100 +</u>
0x+8y=40

8y=40
divide both sides by 8
y=5

Find f(t – 3) for f(x) = 4x2 – 8x + 4.
GarryVolchara [31]

Answer:

4t^2 - 32t + 64.

Step-by-step explanation:

f(x) = 4x2 – 8x + 4

f(t - 3) = 4(t - 3)^2 - 8(t - 3) + 4

= 4(t^2 - 6t + 9) - 8t + 24 + 4

= 4t^2 - 24t + 36 - 8t + 28

=  4t^2 - 32t + 64.

zubka84 [21]

~~~~~~x^2 -10x +10  =0\\\\\implies x^2 -2 \cdot 5 \cdot x +5^2 -5^2 +10 = 0\\\\\implies (x-5)^2 -25+10 = 0\\\\\implies (x-5)^2 -15=0\\\\\implies (x-5)^2 =  15
