Help please :(??? I need an answer
Alecsey [184]

Answer:

C. $23 per day.

Step-by-step explanation:

The equation given is in slope-intercept form: y = mx + b, where m is the rate of change (slope).

In the given equation, m = 23, therefore, the rate of change is 23 units (in this case, dollars per day).

Hope this helps!

Work out an equation of the straight line with gradient 3 that passes through the point with coordinates (2, 4).
Gnom [1K]

Answer:

The answer is

\huge \boxed{y = 3x - 10}

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

where

m is the slope

( x1 , y1) is the point

From the question the point is (2, 4) and the slope is 3

The equation of the line is

y - 4 = 3(x - 2) \\ y + 4 = 3x - 6 \\ y = 3x - 6 - 4

We have the final answer as

y = 3x - 10

Hope this helps you

Find the measure of angle 1<br><br> 60 degrees<br> 72 degrees<br> 36 degrees<br> 54 degrees
GarryVolchara [31]
The sum of all angles (around the black dot) is 360°

All 5 angles (if you forget the red line) are the same; so each angle is 360°/5 = 72°

So Angle 1 is 72°

8x+20y=-120 as slope
Temka [501]

Answer:

y = -2/5x -6

slope is -2/5

y intercept -6

Step-by-step explanation:

8x+20y=-120

Slope intercept form is y = mx+b where m is the slope and b is the y intercept

Subtract 8x from each side

8x -8x+20y= -8x-120

20y = -8x - 120

Divide by 20

20y/20 = -8x/20 -120/20

y = -2/5x -6
