Answer:

A: Not proportional

B: Proportional

Step-by-step explanation:

A: 14/4 = 3.5

40/12 = 0.3333333333333

Therefore A is not proportional

B: 3/9 = 0.3333333333333

15/45 = 0.3333333333333

Therefore B is proportional

Answer:

x=6

Step-by-step explanation:

13x+12=90

13x=78

x=6

The value of x in the rectangle is 6.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The given quadrilateral is a rectangle.

In rectangle each angle has 90 degrees.

So equate 13x+12 and 90 degrees to get x

13x+12=90

Subtract 12 from both sides

13x=90-12

13x=78

Divide both sides by 13

x=6

Hence, the value of x in the rectangle is 6.

#SPJ2

Answer:

b = 0.7

Step-by-step explanation:

to solve the equation, you must isolate "b" so the variable is by itself,,

to do this, divide both sides of the equation by 8:

8b = 5.6

b = 5.6/8

now, simply divide 5.6 by 8 to get your answer,,

b = 5.6/8

b = 0.7

Answer:

a = 6, b = - 12

Step-by-step explanation:

Expand the left side and compare the coefficients of like terms to those on the right side.

a(4x - 10) ← distribute parenthesis

= 4ax - 10a

Compare to 24x + 5b , then

4a = 24 ( divide both sides by 4 )

a = 6

Then

5b = - 10a = - 10(6) = - 60 ( divide both sides by 5 )

b = - 12

Answer:

m∠1 = 112°

Step-by-step explanation:

First, draw a line in the middle of the kite to split it into two isosceles triangles. See the image below for reference.

Because they're isosceles, that means the base angle are congruent. So:

180 = 46 + x + x

180 = 46 + 2x

134 = 2x

x = 67

90 + y + y = 180

90 + 2y = 180

2y = 90

y = 45

x + y = m∠1

67 + 45 = m∠1

m∠1 = 112°

Answer:

40/9

Step-by-step explanation:

9y = -8x + 40

y = -8/9x + 40/9

Answer:

y-intercept or "b"= 40/9 or 4.4444

Step-by-step explanation:

To do this, we use the formula y = mx +b

m= slope

b = y intercept

The equation we are given is 8x +9y = 40.

First, we need to subtract 8x from both sides to isolate the y variable to one side:

8x +9y = 40

9y = -8x + 40

Now, we need to divide both sides by 9, to solve for "y". This will give use the format of y = mx +b.

9y = -8x +40

y = -8/9x + 40/9

Because 40/9 cannot be reduced (besides 4.44), it will be our "b" or y intercept.

y-intercept = 40/9

Answer:

angle 1 should equal to 54.

angle 2 should equal to 126.

Step-by-step explanation:

2x - 8 + 4x + 2 = 180

2x + 4x - 8 + 2 = 180

6x - 6 = 180

6x - 6 + 6 = 180 + 6

6x = 186

6x ÷ 6 = 186 ÷ 6

x = 31

---------------------------------------------

2x - 8 = A1

2(31) - 8 = A1

62 - 8 = A1

54 = A1

-----------------------------------------------

4x + 2 = A2

4(31) + 2 = A2

124 + 2 = A2

126 = A2
