Answer:

x = 1 and x = -1

Step-by-step explanation:

Next time, please separate the equations with a comma or semicolon. Thanks.

We can substitute 4x for y in the quadratic equation x^2 + y^2=17:

x² + (4x)²=17.

Then x² + 16x² = 17, or

17x² = 17, or x² = 1. There are two solutions: x = 1 and x = -1.

Write an equation, in point-slope form, for the line that goes through points (4,4) and (-4,-1).

Soloha48 [4]

Answer:

C.) Y= 5/8x + 1 1/2

Step-by-step explanation:

To write the equation of a line, calculate the slope between points (4,4) and (-4,-1). After, substitute the slope and a point into the point slope form.

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{4--1}{4--4}= \frac{5}{8}$

Substitute m = 5/8 and the point (4,4) into the point slope form.

$y - y_1 = m(x-x_1)\\y -4 = \frac{5}{8}(x-4)\\y-4 = \frac{5}{8}x - \frac{20}{8} \\\y = \frac{5}{8}x - 2{1}{2} + 4 \\ y = \frac{5}{8}x + 1\frac{1}{2}$

Let f(x)=3x^2-8 and let g(x)=4x+1. Find the given value f[g(-1)]

lana [24]

Answer:

Step-by-step explanation:

given:

f(x)=3x²-8

g(x)=4x+1

g(-1) = 4(-1)+1

g(-1) = -4 + 1

g(-1) = -3

hence

f[g(-1)]

= f(-3)

= 3(-3)²-8

= 3(9) - 8

= 19
