What equation do you use to find the slope of a line? I believe it is y=mx+b but I forgot.....

Answer: hehehe

Step-by-step explanation:

Your mom

Since there are complementary angles, the value of angle B is 39°.

Angle A = 7x + 23°

Angle B = 5x + 19°

It should be noted that the total angles in a complementary angle are equal to 90°.

Therefore, we need to add angle A and B together and then equate them to 90°. This will be:

7x + 23° + 5x + 19° = 90°

Collect like terms

12x + 42° = 90°

12x = 90° - 42°

12x = 48°

x = 48°/12

x = 4°

Angle A = 7x + 23° = 7(4) + 23° = 28° + 23° = 51°

Angle B = 5x + 19° = 5(4) + 19° = 20° + 19° = 39°

The value of angle B is 39°.

Answer:

[tex]-1/2[/tex]

Step-by-step explanation:

[tex]-1/2[/tex] is the answer because [tex]-1/2[/tex] is the gradient of the line in the slope. 3 is the y inter. Which is where the line goes over the y-axis.

Hope this helps! (^-^)

Answer:  39/10          

Step-by-step explanation:

Multiply both top and bottom by 10 for every number after the decimal point:

As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,

3.9

1

= (3.9 × 10)

(1 × 10)

= 39/10

Let's solve for variable a ~

Answer:

w = 20

Step-by-step explanation:

2 (3w - 6) = 5w + 8

distribute the 2

6w - 12 = 5w + 8

subtract 5w from both sides

w - 12 = 8

add 12 to both sides

w = 20

Answer:

The value of w is 20.

Step-by-step explanation:

Solution :

[tex]{\longmapsto{\tt{2(3w - 6)=5w + 8}}}[/tex]

[tex]{\longmapsto{\tt{(3w \times 2 )- (6 \times 2)=5w + 8}}}[/tex]

[tex]{\longmapsto{\tt{(6w)- (12)=5w + 8}}}[/tex]

[tex]{\longmapsto{\tt{6w - 12=5w + 8}}}[/tex]

[tex]{\longmapsto{\tt{6w - 5w = 8 + 12}}}[/tex]

[tex]{\longmapsto{\tt{w = 20}}}[/tex]

Hence, the value of w is 20.

Answer:A decrease of 28%

Step-by-step explanation: the question says decreased so you can mark out A and B then 250-180 is 70, 70% of 250 is 28%

The percentage is the indicating hundredth thus the percentage change from $250 to $180 is 28%.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

As per the given question,

Initial price of Airfare = $250

Final price of Airfare = $180

The percentage = change/initial  ×  100

Percentage decrease = (250 - 180)/250  × 100

⇒ 0.28 × 100 = 28%

Hence "The percentage is the indicating hundredth thus the percentage change from $250 to $180 is 28%".

Answer:

x = 9

Step-by-step explanation:

to find the value of x

11x - 11 = 110 (alternate exterior angles are equal)

Substitute

11x = 110 -11

11x = 99

x = 99 ÷ 11

x = 9

Answer:

x=11

Step-by-step explanation:

Because 110= 11x-11, you can use this equation to solve.

First, add 11 to both sides:

121=11x

Then divide by 11:

11=x ------> x=11
