6 0

Sally had 8 dollars right before she was paid for working 4 hours. Sally has at least 32 dollars now.
how much was she paid per hour?
$4x + 8 \geqslant 32$
$4x \geqslant 24$
$x \geqslant 6$
Sally was paid at least 6 dollars /hour.

Proof:-

In ∆XYZ and ∆VWZ

$\because\sf\begin{cases}\sf XZ\cong VZ(Given)\\ \sf YZ\cong WZ(Given)\\ \sf$

Hence

∆XYZ $\cong$ ∆VWZ(Side-Angle-Side)

Find the slope of the line that passes through the following points. Write "undefined" if the slope is undefined.

Katyanochek1 [597]

The slope of the line that passes through the following points is undefined

Solution:

Given that, We have to find the slope of line passing through two points

Given points are (-1, 5) and (-1, 6)

The slope of line is given by formula:

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

From given,

$(x_1, y_1) = (-1, 5)\\\\(x_2, y_2) = (-1, 6)$

Substituting the values we get,

$m = \frac{6-5}{-1-(-1)}\\\\m = \frac{1}{-1+1}\\\\m = \frac{1}{0}$

Thus the slope is undefined

Need help please! Not sure how to do this

Kisachek [45]

This problem is fairly simple if you know the exponential equation, you start with y=78(.17)^x. the you put 10=78(.17)^x, then you solve for x

10=78(.17)^x
-78
-68=.17^x
divide .17 then you have your answer!!
