Step-by-step explanation:

If you are minusing by 5 in the equation then that means that they graph has gone down by 5 units not up. and since 4x and is positive and -2x is negative the graph would flip over the years axis

Answer:

n+5

Step-by-step explanation:

Answer:

n + 5 or 5 + n

Step-by-step explanation:

add 5 to n, tanya's current age, to find how old she'll be in 5 years.

since the variable n is not defined, the answer cannot be simplified further than n + 5.

if n had been defined, you would be able to figure out her exact age after 5 years, which would be the fully simplified answer. for example, if n were to equal 10, then tanya would currently be 10 years old. by plugging in 10 for n in n + 5, you would figure out that in 5 years (aka 10 + 5) tanya would be 15.

13 + 7t - 9

13 - 9 + 7t

4 + 7t

-9n - 8m + 8 - 3n + 6m - 2

-9n - 3n = -12n

-8m + 6m = -2m

8 - 2 = 6

-2m - 12n + 6

-5x + 3y + 9x + 7

-5x + 9x = 4x

3y = 3y

7 = 7

4x + 3y = 7

-2y + 4x - 3y + 6x - 12 for x = 2 and y = -4

Substitute :

-2(-4) + 4(2) - 3(-4) + 6(2) - 12

8 + 8 + 12 + 12 - 12

16 + 12 + 12 - 12

Answer:

y = 40x + 20

Step-by-step explanation:

Answer:

y = 40x + 20

Step-by-step explanation:

Slope Intercept Form :-

> y = mx + c

Here y Intercept is 20 as it passes through (0,20) . And the slope will be ,

> m = 40 .

Therefore Equation :-

> y = 40x + 20

Answer: X = -4

Step-by-step explanation:

90 - 5x + 62 -2x = 180

152 - 7x = 180

-7x = 28

x = -4

Check your answer by pluging in the vaule of x

90 - 5(-4)

90 + 20 = 110

62 - 2(-4)

62 + 8 = 70

110 + 70 = 180

Checks out.

Answer: 110 degrees and 70 degrees

Step-by-step explanation:

These angles are same side (of the traversal line) interior (inside the parallel lines) angles. Same side interior angles sum to 180 degrees. Add the two angles together and set them equal to 180. (90-5x) + (62-2x) = 180

Combine like terms. 90+62= 152 and -5x + -2x = -7x rewrite the equation as 152 + -7x = 180

Subtract 152 from both sides of the equation.

-7x = 28. Now isolate x by dividing both sides by -7. X= -4. Now we can substitute -4 back into the original equations. 90 -5(-4) = 90 +20 = 110 and 62 - 2(-4) = 62 + 8 = 70

We can double check our work to see if these two indeed add up to 180. 110 + 70 = 180

Answer: x=8 angle BDC=77

Step-by-step explanation:

9x-12x=-19-5

-3x=-24

x=8

12x(8)-19

=77

(9x + 5) and (12x - 19) are one angle split equally.

(9x + 5) = (12x - 19)

The value of m∠BDC is 65°

It is a two-dimensional figure which has three sides and the sum of the three angles are equal to 180 degrees.

We have,

(9x + 5) and (12x - 19) are one angle split equally.

So,

9x + 5 = 12x - 19

We will solve for x.

9x + 5 = 12x - 19

Add 19 on both sides.

9x + 5 + 19 = 12x

Subtract 9x on both sides.

24 = 12x - 9x

24 = 3x

Divide both sides by 3.

24/3 = x

x = 7

Now,

The value of m∠BDC.

= 12x - 19

= 12 x 7 - 19

= 84 - 19

= 65°

Thus,

The value of m∠BDC is 65°
