Answer:

Option C -> None of the above.

Step-by-step explanation:

Given-

2 r + ( t + r )

⇒ 2 r + t + r

⇒ 2 r + r + t

⇒ 3 r + t

∵ 2 r + ( t + r ) = 3 r + t.

∴ The given expression is equivalent to Option C : None of the above.

Explanation:

To determine the slope and y-intercept of the equation, let us plot the coordinates in the slope-intercept form.

Analyzing the graph, some of the points that are on the straight line is (1,0),(3,5), (9,20)

Let us consider the points (1,0),(3,5) to determine the slope.

$\begin{aligned}m &=\frac{5-0}{3-1} \\&=\frac{5}{2} \\&=2.5\end{aligned}$

Since, the profit is earned in thousands of dollars, m = 2.5 or m = 2500

Thus, slope = 2500

To determine the y- intercept, let us substitute any one of the coordinate from the graph.

Thus, let us substitute (1,0) in the equation $y=mx+b$ to determine the y-intercept.

$0=2500(1)+b\\$

Simplifying, we have,

$b=-2500$

Hence, the line of best fit equation is $y=2500x-2500$

Someone plsss help me!!!!!

MariettaO [177]

Answer:

x = 2

Step-by-step explanation:

the formula for this problem is

Area = 1/2 base x Height

step 1) plug in what we know

5 = 1/2 base(5)

step 2) switch sides

1/2 base x 5 = 5

step 3) divide both sides by 1/2 x 5

$\frac{1/2 base( 5)}{1/2(5)}$ = $\frac{5}{1/2(5)}$

step 4) Simplify

$\frac{1/2 base (5)}{1/2 (5)}: b$

step 5) Simplify

$\frac{5}{1/2(5)}: 2$

step 6) now you have gotten the answer x = 2

Reptile [31]

Answer:

f(x+2)=3x+10

Explanation:

f(x+2) means replace all the xs with (x+2)

f(x)=3x+4

f(x+2)=3(x+2)+4

Now simplify

f(x+2)=3x+6+4

f(x+2)=3x+10

Answer:

All the options are correct apart from the last one

Step-by-step explanation:

Scale factor is the ratio of corresponding sides

Scale factor = 6.5 / 3.25

Yes

Scale factor = 3.25 / 6.5

Yes

Scale factor = 3 / 1.5

Yes

Scale factor = 1.5 /3

Yes

Scale factor = 1.5 / 3.25

No, as it is the ratio of sides of the same rectangle
