If f(x)=2x+3 and g(x)=x^2 then

f(g(x))=2x^2+3 then:

f(g(-3))=2(-3)^2+3

f(g(-3))=2*9+3

f(g(-3))=18+3

f(g(-3))=21

Kx - c = 9 solve for x

Gennadij [26K]

Answer:

x = $\frac{9+c}{k}$

Step-by-step explanation:

Given

kx - c = 9 ( add c to both sides )

kx = 9 + c ( isolate x by dividing both sides by k )

x = $\frac{9+c}{k}$

1. When you measure the length of an object to the eighth of an inch and again to the fourth of an inch, which measurement is mo

sladkih [1.3K]

Answer:

The eighth of an inch scale measures more precisely.

Step-by-step explanation:

An eighth of an inch means that one inch is divided into 8 equal lengths on the scale i.e. the minimum length that can be measured is $\frac{1}{8} =0.125$ inch.

Again a fourth of an inch means that one inch is divided into 4 equal lengths on the scale i.e. the minimum length that can be measured is $\frac{1}{4} =0.25$ inch.

Therefore, the eighth of an inch scale measures more precisely as it can measure more small measurements. (Answer)
