First distribute:

2*x = 2x

2*-4 = -8

-3*x = -3x

-3*2 = -6

2x-8=-3x-6

Add 8 to both sides (or vise versa add 6 to both sides). You're adding because both the 8 and 6 are negative.

2x=-3x+2

Now add 3x on both sides (or vice versa subtract 2 on both sides).

5x = 2

Now divide. 5x/5 = 2/5

The 5s get canceled out leaving you with x = 2/5.

We can name an angle either by naming its vertex or by three letters , keeping the letter of vertex in between.

so here vertex is F

we can name it as ∠EFG, ∠F , ∠GFE

This strikes out the option B that is ∠G

so option B is the answer

Find the equation of the line perpendicular to y=-2/3x -7 that runs through the points (6,1) in slope intercept form

SVEN [57.7K]

The equation of line is:

$y = \frac{3}{2}x-8$

Further explanation:

Given equation of line

$y=-\frac{2}{3}x-7$

Comparing it with the standard form

y = mx + b gives us:

slope = m1 = -2/3

Let m2 be the slope of second line

The product of slopes of two perpendicular lines is -1.

$m_1* m_2 = -1\\-\frac{2}{3} *m_2 = -1\\m_2 = -1 * -\frac{3}{2}\\m_2 = \frac{3}{2}\\Putting\ in\ standard\ form\\y = \frac{3}{2}x +b$

We have to find the value of b. So, Putting the point(6,1)

$1 = \frac{3}{2}(6) +b\\1 = (3 * 3) + b\\1=9+b\\1-9 =b\\b = -8\\The\ final\ equation\ is:\\y= \frac{3}{2}x -8$

B. 47 degrees

Explanation:
They already cut 43 degrees and they want to cut until a right angle is form which is 90 degrees. To find how much more they have to cut, do 90-43 which gives you 47.

stira [4]

Answer:

Nina practiced the viola for 11.25 hours last week.

Step-by-step explanation:

Juan practiced the violin for 9 hours last week. For each 3 hours that he practices the violin, he practices 2.5 hours of cello. So

3h violin - 2.5h cello

9h violin - xh cello

$3x = 9*2.5$
