Let f(x)=3x-7 and g(x)=2x². Perform the function operation and then find the domain of the result.

olya-2409 [2.1K]

Answer: A

Step-by-step explanation:

$f(x)=3x-7\\g(x)=2x^2$

$(f-g)(x)=3x-7-(2x^2)\\(f-g)(x)=3x-7-2x^2\\(f-g)(x)=-2x^2+3x-7$

The complement of an angle is $5^{\circ}$ more than four times the angle. what is the number of degrees in the measure of the an

Anna11 [10]

Answer:

17°

Step-by-step explanation:

Let x represent the measure of the angle.

(90 -x) = 5 + 4x . . . . the complement is 5° more than 4 times the angle

85 = 5x . . . . . . . . . . add x-5 to both sides

17 = x . . . . . . . . . . . . divide by 5

The measure of the angle is 17°.

Which inequality is NOT true if y = -5?

sertanlavr [38]

Answer:

c is the answer

Step-by-step explanation:

solution

$3y + 9 \geqslant - 15$

$3( - 5) + 9 \geqslant - 15$

$- 15 + 9 \geqslant - 15$

$- 6 \geqslant - 15$

therefore the equation is not true
