Answer:

∠A = ∠B = 80°

Step-by-step explanation:

The angles are corresponding angles where a transversal crosses parallel lines, so are congruent. That means ...

∠A = ∠B

8x -8° = 5x +25° . . . . . substitute the given expressions

3x = 33° . . . . . . . . . . . . add 8°-5x

x = 11° . . . . . . . . . . . . . . divide by 3

Then the angles are ...

8·11° -8° = 80°

Point C has the coordinates (-1,4) and point D has the coordinates (2,0). What is the distance between points C and D? Is ____ u

beks73 [17]

Answer: 5 units

Step-by-step explanation:

$Distance = \sqrt{(x_{2 }- x_{1 })^2 + (y_{2 }- y_{1 })^2\\$

$= \sqrt{(2_ }- (-1)_{ })^2 + (0_{ }- 4_{ })^2$

$= \sqrt{(2_{ }+ 1_{ })^2 + (-4)^2_$

$= \sqrt{3^2+(-4)^2}$

$= \sqrt{9+16}$

$= \sqrt{25}$

$= 5 units$

Given that h(x) = 3x −19, find the value of x that makes h(x) = 71.

rosijanka [135]

Keywords:

<em>Equation, variable, value, clear </em>

For this case we have an equation with a variable of the form $y = h (x)$ . Where $h (x) = 3x-19$ . Given the value of $h (x) = 71$ , we want to find the value of the variable "x". So, we have:

$h (x) = 3x-19\\71 = 3x-19$

We must clear "x", for this, we add "19" to both sides of the equation:

$71 + 19 = 3x-19 + 19\\90 = 3x$

We divide between "3" on both sides of the equation:

$\frac {90} {3} = \frac {3x} {3}\\30 = x$

Thus, the value of the variable "x" is 30.

Answer:

$x = 30$

Option A
