Answer:

5 significant figures

Step-by-step explanation:

looking at the last two digit of the numbers, it multiplication gives, 4*5=20

The sum of Supplementary angle =180 degrees

(2x+3)⁰ +(3x+2)⁰=180⁰

adding like terms

5x+5=180

5x=180-5

5x=175

x=175/5 =35 degrees

so the two angles are :

(2x+3)⁰ =2*35 +3 = 73⁰

(3x+2)⁰=3*35 +2 =105+2 = 107⁰

so correct option is D , 73⁰ and 107⁰

Find the equation of the line that has a slope of 2
alina1380 [7]

Answer:

The equation in the point-slope form will be:

y-(-8) = 2 (x-5)

Step-by-step explanation:

The point-slope form of an equation is written as:

y-y_1=m\left(x-x_1\right)

where m is the slope, and (x₁, y₁) is a point on the line.

Now, we will substitute the values of m and (x1, y1) in the given equation. Here,

m=2

and

(x1, y1) = (5, -8)

x1 = 5

y1 = -8

y-y_1=m\left(x-x_1\right)

y-(-8) = 2 (x-5)

Therefore, the equation in the point-slope form will be:

y-(-8) = 2 (x-5)

Which ordered pair is a solution to this equation?
ElenaW [278]
For (11, 1): (11 + 3)1 = 14(1) = 14
For (5, 2): (5 + 3)2 = 8(2) = 16 ≠ 14
For (7, 2): (7 + 3)2 = 10(2) = 20 ≠ 14
For (3, 2): (3 + 3)2 = 6(2) = 12 ≠ 14

Therefore, (11, 1) is a solution to this equation.

Anna is x years old, her sister Jane is y years younger. What will the sum of there ages be in 3 years. SORRY IM DUMB
r-ruslan [8.4K]

You are not dumb. No one is dumb. Einstein failed math in high school.

Anna is x years old.

Jane is y years younger.

This means the Jane is x - y years old.

In three years, Anna will be x + 3 years old.

In three years, Jane will be (x - y) + 3 years old.

Let S = the sum of their ages in 3 years.

S = x + 3 + (x - y) + 3

S = 2x + 6 - y

Got it?
