So what s the meaning for X and Y

Answer:

z=14

Step-by-step explanation:

-8=2(z-18)

  -8=2z-36

+36     +36

28=2z

28/2=14

z=14

Answer:

z=14. 2(14-18)=2(-4)=-8=-8

Answer:

Step-by-step explanation:

Answer: First, you start with the equation:

9

x

+

4

=

472

Since four students rode in cars, you want to eliminate this part of the problem to find how many students actually rode in the buses

So you would subtract

4

from both sides and get:

9

x

=

468

Finally, you would divide both sides by

9

and get

52

students on each bus

We conclude that the slope of line 'n' is: m₂ = 10

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Given

The slope of line m is: m₁ = 10

It is stated that another line is parallel to line m.

Let m₂ be the slope of the 'n' line.

We know that when two lines are parallel, they have equal slopes.

i.e.  m₁ = m₂

as

The slope of line m is: m₁ = 10

and

The lines are parallel

so

The slope of line 'n' is: m₂ = 10

Therefore, we conclude that the slope of line 'n' is: m₂ = 10.

complet question:

Line m has a slope of 10. Another line n is parallel to line m. What is the slope of line n ?

Answer: m∠GHK=80.5,

m∠KHJ=80.5

Step-by-step explanation:

Answer:

I would say both GHK and JHK equal 80.5 degrees. (if it is allowed with decimals).  

Step-by-step explanation:

Bisectors are lines that basically cut an angle in half. Since JHG is the whole angle, the bisector, HK, halves it. So, both GHK and KHJ should be the same, since they both are half of the original angle. As a result, 161 divided by 2 is 80.5 degrees.

Answer:y = mx + b

Answer:

[tex] \huge{ \bold{ \boxed{ \text{4a + 6}}}}[/tex]

Step-by-step explanation:

[tex] \text{ (3a + 7) + (a - 1)}[/tex]

In addition , sign of each term in the expression remains unchanged. So, Remove the unnecessary brackets.

[tex] \text{⇢ \: 3a + 7 + a - 1}[/tex]

Combine like terms. Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted.

[tex] \text{⇢ \: 3a + a + 7 - 1}[/tex]

[tex] \text{⇢ \boxed{ \text{4a + 6}}}[/tex]

And we're done! :D

Hope I helped!

Best regards! :D

Step-by-step explanation:

Answer:

BC = 3

Step-by-step explanation:

If you picture A, B, and C on a line, the first part of the line, AB, has a length of 5 and the total line, AC, has a length of 8 . Means that the second part of the line, BC, has a length of 3 because you would add the length of both the first and second part of the line in order to get the total length of the line.

AB + BC = AC

5 + BC = 8

BC = 3

Answer:

12

Step-by-step explanation:

Plug in for x first:

Y = -2(x+4) +6

Y = -2((-2)+4) +6

Y = -4 + 6

Y = 2

Then use Y to find W;

W = -3 -2y

W = -3 - 2(2)

W = -3(-4)

W= 12

Answer:

y=8 and w=13

Step-by-step explanation:

y=-2(x+4)

-2x-2=4 sooo...

y=4+4

y=8

then plug 8 into the equation for w

w=-3-2y

then you would get

w=-3-16

-3-16

w=13

Answer:

y=-10x

Step-by-step explanation:

m=-10

For (1,-10) a=1  AND  b=-10

(use the formula y-b=m(x-a) to find the equation of the line)

y-b=m(x-a)

(sub the values of m (the slope) and a&b (from the point)

y - (-10) = (-10) × ( x - 1 )

(simplify)

y+10=-10(x-1)

(expand the bracket)

y+10=-10x+10

(subtract 10 for both sides)

y=-10x+10-10

(simplify)

y=-10x
