If <A and <B are supplementary angles and m<A = 4m<B, find m<A and m<B.

help !!! urgent!!!!!! ​

Answers

Answer 1

Answer:

m∠A = 144°, m∠B = 36°

Step-by-step explanation:

Supplementary angles are angles that add up to 180 degrees.

Substitute 4(m∠B) for m∠A.

4(m∠B) + m∠B = 180

5(m∠B) = 180

m∠B = 36°

Substitute 36 for m∠B.

4(36) = m∠A

m∠A = 144°

9. If AT = 2x + 1, TL = 15, and AL = 7x + 1, select ALL that are true.

Answers

Answer:

B. x = 3

C. Segment AT = 7

F. Segment AL = 22

Step-by-step explanation:

To figure out what the length of Segments AT and AL are use the equation ((2x + 1) + 15) = 7x + 1.

((2x + 1) + 15) = 7x + 1

Add 1 to 15 to get 16.

2x + 16 = 7x + 1

Subtract 7x from both sides. This cancels the +7x.

2x + 16 - 7x = 1

Combine 2x and -7x to get -5x

-5x + 16 = 1

Subtract 16 from both sides. This chancels the +16x.

-5x = 1 - 16

Subtract 16 from 1 to get -15.

-5x = -15

Divide both sides by -5. This cancels the multiplication by -5.

x = -15/-5

Dividing any two negative numbers ends in a positive. Divide -15 by -5 to get 3.

x = 3

Now, substitute x for 3 in 2x + 1 and 7x + 1 to figure out the lengths.

2(3) + 1

Mulitply 2 by 3 for 6.

6 + 1

Add 1 to 6 to get 7.

Segment AT is 7 units long.

7(3) + 1

Multiply 7 by 3 to get 21.

21 + 1

Add 1 to 21 to get 22.

Segment AL is 22 units long.

A line with a slope of 10 passes through the point (0, 10). What is its equation in
slope-intercept form?

Answers

Answer:

y = 10x + 10

Step-by-step explanation:

(0,10) means that the y is 10 when the x is 0, which is the y-intercept

y-intercept: 10

b = y-intercept

m = slope

slope: 10

y = mx + b

y = 10x + 10

Find the slope and the y-intercept of the equation 4x + 5y=-9.
O A. slope = 4/5' and y-intercept = `-(9)/(5)
slope = '-(4)/(5) and y-intercept = (9)/(5)
OC. slope = \-(4)/(5) and y-intercept = -(9)/(5)
OD. slope = (4)(5) and y-intercept = `975

Answer:

  4

Step-by-step explanation:

The slope formula is useful:

  m = (y2 -y1)/(x2 -x1)

  m = (13 -5)/(4 -2) = 8/2

  m = 4

The slope of the line through those points is 4.

A25f oz. botie of Tide detergent costs $3.99 and a 90 fl oz. bottle of Tide detergent costs $6.99. Is the 25 oz or 90 oz bottle of Tide a better

buy?

Answers

Answer:

The 90 oz bottle of Tide is the better buy because it has a lower price per oz.

Step-by-step explanation:

To find the bottle of Tide that is a better buy, you have to divide each price for the number of ounces they have and determine the one that has the lower price per ounce.

$3.99/25= $0.15

$6.99/90= $0.07

According to this, the answer is that the 90 oz bottle of Tide is the better buy because it has a lower price per oz.

IF NQZ IS SIMILAR TO CBK, FIND BK

Answers

Answer:

Bk = 65

Step-by-step explanation:

BK as we can see is 4x + 1

If two triangles are similar, the ratio of the corresponding sides are the same

Thus;

2x+7/27 = 4x + 1/45

45(2x + 7) = 27(4x + 1)

90x + 315 = 108x + 27

108x-90x = 315-27

18x = 288

x = 288/18

x = 16

From the question;

BK = 4x + 1

BK = 4(16) + 1

BK = 64 + 1

BK = 65
