Answers

Answer:

Step-by-step explanation:

Slope m is defined as m=(y2-y1)/(x2-x1) in this case

m=(218-155)/(22-15)=63/7=9

y=mx+b

y=9x+b, using point (15,155) we can solve for the y intercept b

155=9(15)+b

155=135+b, b=20 so the line is

y=9x+20

Step-by-step explanation:

15j + 12k = 18
5j + 4k = 6

Answers

Using substitution or elimination?

1. multiply the first or second equation by a number that will make one variable 0
For example; if you multiply the bottom equation by “-3”, it will be “-15j-12k=-18”

2. add the two equations together
It will be 15j-15j which equals 0. Additionally, 12k-12k=0. And, 18-18=0

This means that you have 0=0. When this happens, you have infinitely many solutions. Your teacher may only want you to put infinitely many, or they may want you to solve in terms of one of the variables. If it is the latter, let me know and I will help with that.

a customer left a tip of 25$ this is 20% of his bill. whats the price of the bill?

Answers

Answer:

i think 150

Step-by-step explanation:

Answer: $30.00

Step-by-step explanation:

First, convert the 20% to an actual number that can be used in a calculation. For percents, this is always done by simply dividing the percent (in this case 20%) by 100%.So, the conversational term "20%" becomes 20% / 100% = 0.20 in terms of a real mathematical number.

0.20 x $25.00=$5.00.

$25.00 + $5.00 = $30.00.

A line passes through the point A (-2,-5) and has a slope of -9. Using the point-Slope formula, express the equation of the line in slope intercept form.

Answers

Answer:

y = -9x -23

Step-by-step explanation:

Point-slope formula gives you

y -(-5) = -9(x - (-2))

y + 5 = -9(x + 2)

y + 5 = -9x - 18

y = -9x -23

Lilly opens an account with $60. Each week she deposits $12. Write an expression to show the amount she has after w weeks.

Answers

Answer:

5 weeks

Step-by-step explanation:

so if Lily has $60 and takes out (subtracts) 12 a week then it would look like this

TOTAL STARTED WITH EACH WEEK

$60 -12 48

$48 - -12 36

$36 -12 24

$24 -12 12

$12 -12 0

In the figure below, UX and UV are tangent to the circle centered at 0. The segment XV passes through the center of the
circle. Given that UX= 15.7 and XV = 8.5, find XW.
Help

Answers

Answer:

2.5

Step-by-step explanation:

The computation of the XW is shown below

As triangle UVX is a right angle

VU^2 = XU^2 - VX^2

VU^2 = 15.7^2 - 8.5^2

VU^2 = 246.49 - 72.25

VU^2 = 174.24

VU = 13.2

As VU = WX because of same point tangent

NOw XW is

= UX - UW

= 15.7 - 13.2

= 2.5

Answers

Answer:

You just subtract 126 degrees from 180 degrees = 34 degrees for all angles

The measures of the angles ∠2,∠4,∠6, and ∠8 are 54°, 54°, 54°, and 54° respectively or all the angles are the same.

It is given that in the figure the line p and line q are parallel to each other.

It is required to find the measures of all angles.

What are vertically opposite angles?

It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.

We have two lines p and q which are parallel to each other, line t is crossing both lines as shown in the figure.

∠1 = 126° and ∠3 = 126°

For the angles ∠2 and ∠4:

∠2 = 180° - 126° ⇒ 54°

From the definition of the vertically opposite angle:

∠2 =∠4 = 54°

∠5 = 126° and ∠7 = 126°

∠8 = 180 - 126° = 54°

From the definition of the vertically opposite angle:

∠8 = ∠6 = 54°

Thus, the measures of the angles ∠2,∠4,∠6, and ∠8 are 54°, 54°, 54°, and 54° respectively or all the angles are the same.

In the figure MN is a midsegment of JKL. Find the value of X

Answers

Answer:

x = 9

Step-by-step explanation:

Here, we want to find the value of x

To do this, we are going to use the similar triangles principle

When two triangles are similar, the ratio of their corresponding sides are the same

The two similar triangles we shall be using are;

LMN and LJK

Thus, we have it that;

x/8.5 = x+ 9/17

17x = 8.5(x + 9)

17x = 8.5x + 76.5

17x - 8.5x = 76.5

8.5x = 76.5

x = 76.5/8.5

x = 9
