Question 8 should be y=-5/2x-1. And question 9 should be y=1/2x-7.
A.In Step 2, 90 should be multiplied by the quantity 10 – 12, not by 10.
correct:
90(10 - 12) = 90 · 10 - 90 · 12 or 90(10 - 12) = 90 · (-2)
Answer:
A.
Step-by-step explanation:
First write the picture down like so:
x(8) divided by 10.9 - 7.9 then go down the row wel 10.9 x 8 = 87.2 divide that by 10.9 and youll get 8 then subtract 8 from 7.9 and you will get 0.1
The one with the fraction in the parenthasees
remember
F=P(r)^t
in decay, r<1
in growth, r>1
and r is positive so we don't have wierd fliping values
answer would be f(x)=4(0.25)^x
2nd one is answer
First number = x
Second number = x + 2
Third number = x + 4
X + x +2 + x + 4 = 438
Simplify:
3x + 6 = 438
Subtract 3 from both sides
3x = 432
Divide both sides by 3
X = 144
The second number is 144 + 2 = 146
