Answer:

Ming has described a proportional relationship because the ordered pairs are linear and the line passes through the origin

Step-by-step explanation:

Given

x - y

5 - 10

10 - 20

15 - 30

Required

Determine if the data are proportional

The dataset is small; so, we can derive the relationship by observation.

By observing the x and y values, the relationship is:

y = 2x --- i.e. multiply x values by 2.

This is further proven by:

y = 2 * 5 = 10

y = 2 * 10 = 20

y = 2 * 15 = 30

y = 2 * 0 = 0 --- the origin

Hence, the dataset is proportional and it passes through the origin.

∠A and ∠ B ∠B are complementary angles. If m ∠ A = ( x − 23 ) ∘ ∠A=(x−23) ∘ and m ∠ B = ( 2 x + 29 ) ∘ ∠B=(2x+29) ∘ , then find
Dafna1 [17]

Answer:

85

Step-by-step explanation:

2x + 29 + x - 23 = 180

solve for x = 28

b = 2 * 28 + 29 = 85

The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.
Svetach [21]

Let

angle 1=2x°

angle 2=2x°

angle 3=124°

angle 4=124°


we know that

The interior angles formed by the sides of a quadrilateral have measures that sum to 360°

so

angle 1+angle 2+angle 3+angle 4=360°

2x+2x+124+124=360\\ 4x+248=360\\ 4x=112\\ x=28degrees

therefore


the answer is

x=28degrees
