5 0

Answer:

It would be 39 degrees. A right triangle has 180 all together. So, you add 90+51=141 and take 180-141=39

There are 24 counters. How many counters could you add without having to regroup? Explain.
PIT_PIT [208]
The answer to this question would have to be 5. In the statement given we can add 5 more that is 24 _ 5 equal to 29. Once the counter reaches 30, one must have to regroup by exchanging 10 ones for a 10 bar.Hence the answer to this problem would have to be 5 counters

Write an equation of the line passing through the point (2,8) that is perpendicular to the line 2x-3y=7
labwork [276]

Answer:

y = (-3/2x) + (35/4)

Step-by-step explanation:

So the perpendicular line will have a slope that is the opposite reciprocal of the other line's slope. Solve for the original line's slope first:

2x - 3y = 7 --> -3y = -2x + 7 --> y = (2x/3) - (7/3)

So, the slope of the perpendicular line will be (-3/2x)

Solve for the y-intercept of the perpendicular like by using the linear equation and substituting in (2,8):

8 = (-3/(2*2)) + b --> (32/4) = -(3/4) + b --> b = (35/4)

So, y = (-3/2x) + (35/4)

Hope that helps! :D

If one point on a horizontal line has coordinates (3, 2), which of the points below are also on the line? Select all that apply.
stepan [7]

Answer:

If the line is horizontal, then all that have a 2 in the Y space will apply because the line goes across meaning that it won't change on the vertical axis.

(5,2) and (-2, 2)
