Answer:

Y=2/3x -2

Step-by-step explanation:

Slope 2/3

Y intercept -2

The equation which has a slope of 2/3 and a y-intercept of (0, -2) is; 2x -3y = 6

From line geometry, it follows that the slope of a given straight line is the rate of change in variable y due to a change in variable x.

Hence, the resulting equation is;

Answer:

The answer is B.180°.

Step-by-step explanation:

The figure is rotationally symmetric is after a rotation of a given angle, it still look the same.

In this case of a rectangle, the only way to rotate it so that is look the same, is by rotating it by multiple of 180°, so that the up and down sides flip over, as well as the right and left sides.

Therefore, the only option that applies is B.180°

Answer:

B

Step-by-step explanation:

Answer:

Step-by-step explanation:

When the sum of two angles is 90°, then the angles are known as complementary angles. In other words, if two angles add up to form a right angle, then these angles are referred to as complementary angles. Here we say that the two angles complement each other. Suppose if one angle is x then the other angle will be 90 o – x

Answer:15

Step-by-step explanation:

Answer:

The answer is B) 75

Step-by-step explanation:

The angle shown is a 90-degree angle. Therefore if the other angle is 15 degrees, that means that all we have to do is subtract 15 from 90.

90-15= 75 which means the angle known as x is a 75-degree angle.

Answer:

A. d = 25; the unit rate is 25 miles per gallon

Step-by-step explanation:

The point (1, d) on the graph represents (x, y), where,

x = gasoline used = 1 gallon

y = distance = d = 25 miles

That is, (1, d) represents when x = 1, y = 25.

Thus, (1, 25) is the unit rate which is 25miles per gallon.

x = 9

y = 6

Step-by-step explanation:

ΔABC ~ ΔPQR

Therefore, corresponding sides of these similar triangles will be in the proportional.

[tex]\frac{AB}{PQ}=\frac{BC}{QR}= \frac{AC}{PR}[/tex]

[tex]\frac{6}{x}= \frac{4}{y}= \frac{8}{12}[/tex]

[tex]\frac{6}{x}= \frac{8}{12}[/tex]

x = [tex]\frac{12\times 6}{8}[/tex]

x = 9

Similarly, [tex]\frac{4}{y}= \frac{8}{12}[/tex]

y = [tex]\frac{12\times 4}{8}[/tex]

y = 6

Answer:

Step-by-step explanation:

A=LW, L=A/W

P=2(L+W), using L=A/W we get

P=2(A/W+W)

P=2(A+W^2)/W

PW=2A+2W^2

2W^2-PW+2A=0, given A=28 and P=22 we have

2W^2-22W+56=0

2(W^2-11W+28)=0

2(W-7)(W-4)=0

So the dimensions are 4ft by 7ft

Answer:

1) 5% of 90m= 4.5m

2)25% of 88kg = 22kg

3) 75% of 264= 198

Step-by-step explanation:

1) 90m = 100% (divide by 10)

9 = 10% (divide by 2)

4.5 = 5%

2) 88kg = 100% (keep on dividing by 2)

44kg = 50%

22kg=25%

3) 264 = 100%

132 = 50%

66 = 25% (add)

198=75%
