describe the steps you used to solve the equation and find the amount of carries allowance. linear equation: 1/4a+1/3a+8=22

vlabodo [156]

1/4a + 1/3a +8 =22

1st step add like terms:

1/4a +1/3a = 3/12a +4/12a = 7/12a

7/12a +8 =22

2nd step subtract 8 from each side:

7/12a = 14

3rd step divide both sides by 7/12 to get a:

a = 14 / 7/12

a = 24

Equation parallel to y = -x is y=-x+k

so 4.5 = -7 + k so k - 11.5

Equation is y = -x + 11.5

Use Synthetic substitution to find f(3) and f(-4) for f(x)=x^4-8x-11

brilliants [131]

Answer:

46 and 277

Step-by-step explanation:

Given

f(x) = $x^{4}$ - 8x - 11 ← substitute x = 3, x = - 4 into f(x)

f(3) = $3^{4}$ - 8(3) - 11 = 81 - 24 - 11 = 81 - 35 = 46

f(- 4) = $(-4)^{4}$ - 8(- 4) - 11 = 256 + 32 - 11 = 288 - 11 = 277
