Find the slope line (-2 -1) and (-4 -7)

Alenkinab [10]

Answer:

$m=3$

Step-by-step explanation:

Slope formula

$m=\frac{y_2-y_1}{x_2-x_1}$

Here

$(x_1, y_1) = (-2, -1) \ \ and \ \ (x_2, y_2) = (-4, -7)$

Slope can be calculated as

$m=\frac{-7-(-1)}{-4-(-2)}$

$m= \frac{-6}{-2} \\m=3$

Given: f(x) = 2x + 5 and g(x) = x2 and h(x) = -2x<br><br> h(g(f(x)))

alexgriva [62]

Hello here is a solution :
<span>h(g(f(x))) ?

</span>g(f(x))= g(2x+5)=(2x+5)²=(2x)²+2(2x)(5)+5² = 4x²+20x+25
h(g(f(x)))(x) = h(4x²+20x+25) = -2(4x²+20x+25)
h(g(f(x)))(x) = -8x²-40x-50

What is the y-intercept of the line that passes

lara [203]

The slope is

$\frac{-13-31}{1-(-10)}=-4$

So, the equation is

$y+13=-4(x-1)$

The y-intercept is when x=0, so

$y+13=-4(0-1) \\ \\ y+13=4 \\ \\ \boxed{y=-9}$

Answer:

Step-by-step explanation:

base = 7 units

height = 12 unit

Area of triangle = $\frac{1}{2}*base * height\\$

$= \frac{1}{2}*12*7\\\\=6 * 7 \\= 42 unit^{2}$
