Question down below down below

Mathematics
1 answer:
ser-zykov [4K]3 years ago
3 0

Answer:

C

Step-by-step explanation:

y = 2.5 x - 57

y = Profit: 143

143 = 2.5 x - 57                     Add 57 to both sides

143 + 57 = 2x - 57 + 57    Combine like terms

200 = 2.5 x                          Divide by 2.5

200/2.5 = 2.5x/2.5

x = 80 plants

A circle has a center located at 2 5 and passes through the point 10 3 answer
nikklg [1K]

Answer:Explanation: The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. If a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

Which of these functions had a greater rate of change than the function graphed below, and why?
Mrac [35]

Answer:

C

Step-by-step explanation:

When we talk of rate of change, we talk of the slope of the line

If we had a line;

y = mx + b

m is the slope ( which is the rate of change)

To get the slope of the line, we select any two points on the line and apply the slope formula

m = y2-y1/x2-x1

let us take points (0,0) and (3,9)

m = 9-0/3-0 = 9/3 = 3

The slope here is 3

so from the option, we can see that the third option is the correct answer

9a-4+3(a-11)=23 how would i solve using multi step equations variables on both sides
GalinKa [24]
9a-4+3a-33=23
9a+3a-29=23
+29 +29
9a+3a=52
-3a -3a
9a=52-3a
9a/9=52/9- 3a/9


a=52/9-1/3a
