KiRa [710]3 years ago
5 0

Answer:

20% of a is 11, what is a

a =55

75% of b is 12, what is b

b = 16

80% of c is 20, what is c

c = 25

200% of d is 18, what is d

d = 9

Step-by-step explanation:

20% of a is 11, what is a

20a = 1100

a =55

75% of b is 12, what is b

75b = 1200

b = 16

80% of c is 20, what is c

80c = 2000

c = 25

200% of d is 18, what is d

200d = 1800

d = 9

Write an equation in point-slope form of the line that passes through the point (2, -8) and has a slope of 4. The equation is y-
Lorico [155]

Answer:

The equation is y-(-8) = 4(x-2).

Step-by-step explanation:

The point-slope form of a line is represented by the formula y-y_1 = m (x-x_1). In order to write an equation of a line in point-slope form, we would need to substitute real values for the m, x_1, and y_1 in the formula.

Since m represents the slope of the line, substitute 4 in its place. Since x_1 and y_1 represent the x and y values of one point the line intersects, substitute the x and y values of (2,-8) in the formula as well. Substitute 2 for x_1 and -8 for y_1. This results in the following equation and answer:

y-(-8) = 4(x-2)

(Usually, we would simplify the double negatives on the left side to a positive, but because you have to type the values in to answer the problem and cannot change the written negative sign already visible in the equation, that would be the answer. I believe you can just type in -8 for the first box.)

How can you determine the coordinates of any image that is dilated with the center of dilation at the origin without graphing? E
julsineya [31]

Answer:

See explanation

Step-by-step explanation:

Let (x,y) be the coordinates of the point which has to be dilated with the scale factor of k with the center of dilation at point (0,0) (the origin).

The dilation with the scale factor k and the center of dilation at the origin has the rule

(x,y)\rightarrow (kx,ky)

So, you have simply to multiply each coordinate of the point by k to get the image's coordinates.
