2(x-7)/3=-2
3*2(x-7)/2*3=-2*3/2
x-7=-2*3/2
x-7=3*-1
x+(7-7)-7-3
x=7-3
x=4
Answer:
Scaling
Step-by-step explanation:
That's the definition:
Scaling is the process that resizes a number when you multiply by a fraction that is greater than or less than one.
35 =
(3.14)(r²)(2.4)
35 =
(7.536)(r²)
35 = <span>2.512 r</span>²
35 ÷ 2.512 = 14
2.512 ÷ 2.512 = 1
14 ≈ r²
√14 ≈ √r²
3.74165 ≈ r
I'd say A would be the answer!
Answer:
1) 2x-5 2) -10/x^2
Step-by-step explanation:
Use power rule and constant rule for the first one:
1) f(x)=x^2-5x^1+1 (x^n)'=nx^(n-1) and (c)'=0
f'(x)=2x^1-5(1)x^0+0
f'(x)=2x-5(1) x^0=1
f'(x)=2x-5
Use just power rule for last one after a rewrite
2) f(x)=10/x
f(x)=10x^(-1) now use power rule
f'(x)=-10x^(-2) =-10/x^2
