Answer:

C

Step-by-step explanation:

Observing that <em>f</em> has to be placed inside <em>g</em>, we can easily substitute x^2 - 3 in place of the x in x + 1, making it

(x^2 - 3) + 1 which equals

(x^2) - 2

A quadtratic equation that has x intercepts of -8,0 and 2,0 and has a vertical stretch of 3

Paladinen [302]

Answer:

f(x) = 3(x + 8)(x - 2)

Step-by-step explanation:

The intercept form of a quadratic function is y = a(x - r)(x - s), where r and s are the x-intercepts and a is the vertical stretch/compression factor.

If the intercepts are at (-8, 0) and (2, 0), and the vertical stretch is 3, just substitute these values into the intercept form formula, and you're done!

Solve for x ~<br><img src="https://tex.z-dn.net/?f=3%20%5C%3A%20%2814%20-%205x%29%20%3D16%20-%20%2012x" id="TexFormula1" title="

$3(14 - 5x) = 16 - 12x$

Distribute 3 throught the parentheses

$42 - 15x = 16-12x$

Move the variable to the left-hand side and change its sign

$42 - 15x + 12x = 16$

Move the constant to the right-hand side and change its sign

$- 15x+12x=16 - 42$

Collect like terms

$- 3x = - 26$

Divide both sides of the equation by -3

$\boxed{x = \frac{26}{3} }$

Solve using the elimination method:<br> X-3y=7<br> 3x + 3y=9

sergij07 [2.7K]

Answer:

$x=4\\\\y=-1$

Step-by-step explanation:

Given Equation:

$x-3y=7$ Equation:1

$3x + 3y=9$ Equation:2

Dividing Equation:2 by '3' both the sides:

$x+y=3$

or $x=3-y$ Equation:3

Putting the vale of 'x' in Equation:1

$x-3y=7$

$(3-y)-3y=7\\\\3-y-3y=7\\\\3-4y=7\\\\$

Subtracting '3' both sides

$-4y=7-3\\\\-4y=4$

$y=\frac{4}{-4}$

$y=-1$

Putting value of 'y' in Equation:3

$x=3-y$

$x=3-(-1)\\\\x=3+1\\\\x=4$

The solution of the equations is :

$x=4\\\\y=-1$
