Answer:

Step-by-step explanation:

Your score total must be 3×75 = 225. Subtracting the two high scores gives ...

225 -95 -79 = 51

The score of 34 is below that value, so it is the one that will be dropped.

You need a test score of 51 on the next test for your average to be 75.

Write an equation in slope-intercept form for the line that passes through (5,0) and is perpendicular to the line described by y

natta225 [31]

For this case we have to;

We have that an equation in slope-intercept form is given by:

$y = mx + b$

Where:

m is the slope

b is the cut point with the y axis

Also, by definition, two lines are perpendicular when the product of their slopes is -1. That is: $m_ {1} * m_ {2} = - 1$

We have the line as data: $y_ {1} = \frac {-5} {2} x + 6$

Then $m_ {1} = \frac {-5} {2}$

We found $m_ {2}$ :

$m_ {1} * m_ {2} = - 1$

$\frac {-5} {2} * m_ {2} = - 1$

$m_ {2} = \frac {-1} {(\frac {-5} {2})}$

$m_ {2} = \frac {(2) (- 1)} {(- 5) (1)}$

$m_ {2} = \frac {2} {5}$

Thus, $y_ {2} = \frac {2} {5} x_ {2} + b_ {2}$

We must find $b_ {2}$ :

We know that $y_ {2}$ passes through the point $(x_ {2}, y_ {2}) = (5,0)$

We substitute the point in the equation of $y_ {2}$ :

$0 = \frac {2} {5} (5) + b_ {2}\\0 = 2 + b_ {2}\\b_ {2} = - 2$

Thus, $y_ {2} = \frac {2} {5} x_ {2} -2$

Then the equation in slope-intercept for the line that passes through (5,0) and is perpendicular to the line described by $y_ {1} = \frac {-5} {2} x_{1} + 6$ is: $y_ {2} = \frac {2} {5} x_ {2} -2$

Answer:

$y_ {2} = \frac {2} {5} x_ {2} -2$

An angle measures 94" more than the measure of its supplementary angle. What is the

PIT_PIT [208]

Answer:

The measure of the angles are 137 and 43

Step-by-step explanation:

Firstly, we need to understand what is meant by saying two angles are supplementary.Two angles are termed supplementary if the addition of the value of both angles equal 180.

Now let the two angles we are seeking in this question be x and y respectively

We write our first equation using the supplementary information;

x + y = 180 •••••••••••(i)

Secondly we are made to know that the difference between these angles is 94

Mathematically;

x - y = 94

or simply x = 94 + y; insert this into equation 1 above

94 + y + y = 180

2y = 180 - 94

2y = 86

y = 86/2

y = 43

x = 94 + y = 94 + 43 = 137
