Answer:
m∠ONB = 81°
Step-by-step explanation:
If angle MNJ and angle ONB are congruent and MNJ is 81 degrees and OJ is a straight line then ONB should also be 81 degrees in which the other side is 99 degrees.
Which of the points A (5, −3),B (−2, 4), C (0, 0),D (2, 1), E (−5, 2.5) belong to the graph of the direct variation y = 1/2 x ?
Answer:
A (5,-3) does not belong
B (-2,4) does not belong
C (0,0) belongs
D (2,1) belongs
E (-5,2.5) does not belong
Step-by-step explanation:
To find the answer, you'll need to know
what is the number in half? If (x,y) is like
10,5 then that will belong.

15. Find the coordinates of D, the midpoint of AB.
16. Find the length of the median CD.
17. Find the coordinates of the centroid. Label this point as G.
Answer:
Step-by-step explanation:
15) point D=(3,1)
for AB we can see that there is an exact triangle of 2 and 5
so AD = [tex]\sqrt{2^{2} +5^{2} }[/tex] = [tex]\sqrt{29}[/tex] and 2(AD) = AB
AB = 2*[tex]\sqrt{29}[/tex] ( this is an exact answer, leave it with the square root)
16) find CD length we know the points at each end so use the distance formula P1=(-3,4) P2=(3,1)
Dist. = [tex]\sqrt{(3-(-3))^{2} +(1-4)^{2} }[/tex]
Dist. =[tex]\sqrt{45}[/tex] = [tex]\sqrt{9*5}[/tex] = 3[tex]\sqrt{5}[/tex] ( exact answer leave the square root )
CD = 3[tex]\sqrt{5}[/tex]
17) 1/3 of the way along CD from D towards C is where the centroid is.. I just happen to know that from doing this too often. :/
so that mean [tex]\frac{1}{3}[/tex] * [tex]3\sqrt{5}[/tex] is the distance from D to the centroid or [tex]\sqrt{5}[/tex]
also b/c I happen to know.. :/ c = [tex]\sqrt{1^{2}+ 2^{2} }[/tex] = [tex]\sqrt{5}[/tex] off the top of my head I can see that the point (1,2) is our centroid for this object.. they made it really easy ... okay.. relatively easy. .:D
Centroid = (1,2)

Can someone help me with this? I just need help understanding it.
What expression can you substitute for y in
this equation?
-4y + x = -27
Enter the correct answer.
Answer:
1/4x+27/4
Step-by-step explanation:
Here's the equation: -4y+x=-27
We'll need to isolate y on one side
subtract x from both sides
-4y=-x-27
divide everything by -4
y=1/4x+27/4
So you can substitute 1/4x+27/4 for y.
hope this helps!

Select all equations that have graphs with the same y-intercept.
y = 3x - 8
y = 3x - 9
y = 3x + 8
y = 5x - 8
y = 2x - 8
y = (1/3)x - 8
The equations that have graphs with the same y-intercept are:
y = 3x - 8y = 5x - 8y = 2x - 8y = (1/3)x - 8To determine which equations have graphs with the same y-intercept, we need to look for equations that have the same constant term when written in the form y = mx + b, where m represents the slope and b represents the y-intercept.
The y-intercept is the value of y when x is equal to 0. In other words, it is the point where the graph intersects the y-axis.
Let's compare the equations and their constant terms:
y = 3x - 8 (Constant term: -8)
y = 3x - 9 (Constant term: -9)
y = 3x + 8 (Constant term: 8)
y = 5x - 8 (Constant term: -8)
y = 2x - 8 (Constant term: -8)
y = (1/3)x - 8 (Constant term: -8)
From the comparison, we can see that the equations y = 3x - 8, y = 5x - 8, y = 2x - 8, and y = (1/3)x - 8 all have the same constant term of -8. This means that their graphs will have the same y-intercept, which is -8.
Therefore, the equations that have graphs with the same y-intercept are:
y = 3x - 8
y = 5x - 8
y = 2x - 8
y = (1/3)x - 8

6 is 16% of what number?
Answer:
37.5
Step-by-step explanation:
Answer:
6 is 16% of the number 37.5
Step-by-step explanation:
We have, 16% × x = 6
or, 16/100 × x = 6
Multiplying both sides by 100 and dividing both sides by 16,
we have x = 6 × 100/16
x = 37.5

A plumber charges $65 to make a house call plus an additional charge of $42 per hour for labor. Write an equation to represent the total cost (y) for any number of hours (x).
Answer:
the required equation to represent the total cost with respect to every hour will be
=》y = 42x + 65
Step-by-step explanation:
total cost (y) = charge to make a house call + additional charge for every our
so, total additional charge for x hours
= 42 × x = 42x
hence y = 65 + 42x ( where 65 is charge to make a house call , y is total cost and 42x is additional charge for x hours )
