Answer:

x = - 8, x = 2 are the solutions

Step-by-step explanation:

Given

x² + 6x - 16 = 0

Consider the factors of the constant term (- 16) which sum to give the coefficient of the x- term (+ 6)

The factors are + 8 and - 2 , since

8 × - 2 = - 16 and 8 - 2 = + 6 , thus

(x + 8)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 8 = 0 ⇒ x = - 8

x - 2 = 0 ⇒ x = 2

X-intercept and y-intercepts og y=x^2-3

Rufina [12.5K]

Answer:

Part 1) The y-intercept is the point $(0,-3)$

Part 2) The x-intercepts are the points $(-\sqrt{3},0)\ and\ (\sqrt{3},0)$

Step-by-step explanation:

we have

$y=x^{2}-3$

This is a vertical parabola open upward

step 1

Find the y-intercept

we know that

The y-intercept is the value of y when the value of x is equal to zero

For x=0

$y=(0)^{2}-3$

$y=-3$

The y-intercept is the point (0,-3)

step 2

Find the x-intercepts

we know that

The x-intercept is the value of x when the value of y is equal to zero

For y=0

$x^{2}-3=0$

solve for x

Adds 3 both sides

$x^{2}-3+3=0+3$

$x^{2}=3$

take square root both sides

$x=(+/-)\sqrt{3}$

The x-intercepts are the points $(-\sqrt{3},0)\ and\ (\sqrt{3},0)$

The triangles are similar. The area of the larger triangle is 270 square centimeters. What is the area of the smaller triangle?

Vitek1552 [10]

The smaller triangle is 1/6 the size of the large one ( 5/30 = 1/

Area is squared 1/6 ^2 = 1/36

Multiply the area of the large triangle by 1/36:

270 x 1/36 = 270 /36 = 7.5

The area is 7.5 cm^2

The answer is A.

What is the slope of the line created by this equation?Round your answer out to two decimal places.3x+5y=7

tia_tia [17]

The given equation is

$3x+5y=7$

Consider the slope-intercept form.

$y=mx+b$

Rewriting the given equation in the slope-intercept form.

$3x+5y=7$

Subtracting 3x from both sides, we get

$3x+5y-3x=7-3x$

Dividing both sides by 5, we get

$\frac{5y}{5}=\frac{7-3x}{5}$ $y=-\frac{3}{5}x+\frac{7}{5}$

$y=-0.6x+1.4$

Compared to the slope-intercept form, we get m=-0.6 and b=1.4.

Hence the slope m= -0.60.
