3) Let h(x)= |2x|-4. Find h(x) when x = -7. a) -10 b) 10 c) -13 d) 13

svlad2 [7]

Answer:

$h(x) = 10$

Step-by-step explanation:

Given

$h(x) = |2x| - 4$

$x = -7$

Find h(x)

Substitute -7 for x

$h(x) = |2*-7| - 4$

$h(x) = |-14| - 4$

Absolute values return positive. So:

$h(x) = 14 - 4$

$h(x) = 10$

A family built a house in a beach resort area. In 1990, the house was 430 ft from the water. With erosion, the house was 400 ft

neonofarm [45]

We develop an equation for the given situation by first writing the general equation for lines,

y = mx + b

Substituting to this given the values given above,

(1990) 430 = b

(2000) 400 = m(10) + 430

The value of m from the equation in 2000 is -3. Thus, the equation of that relates the variables is,

y = -3x + 430

How do you calculate the midpoint of question e)? I am very desperate. please help

andrey2020 [161]

Answer:

(-1,-1)

Step-by-step explanation:

Midpoint equation: $(\frac{x_2+x_1}{2}, \frac{y_2+y_1}{2})$

= $(\frac{-5/2+1/2}{2},\frac{-1/2-3/2}{2} )$

= $(\frac{-2}{2},\frac{-2}{2})$

=(-1,-1)

Use the formula and plug it in :)
