2c +3 = 3c - 4<br> Help me please
VashaNatasha [74]

Hey there!

<u>Solve </u><u>the </u><u>equation</u><u>:</u>

  • Answer :

c = 7 ✅

  • Explanation

2c + 3 = 3c - 4

<em>></em><em>></em><em> </em><em>Subtract </em><em>3</em><em> </em><em>from </em><em>both </em><em>sides </em><em>:</em>

<em> </em>

2c + 3 - 3 = 3c - 4 - 3

2c = 3c - 7

<em>></em><em>></em><em> </em><em>Substrat </em><em>3</em><em>c</em><em> </em><em>from </em><em>both </em><em>sides </em><em>:</em>

2c - 3c = 3c - 7 - 3c

-c = -7

<em>></em><em>></em><em> </em><em>Divide</em><em> </em><em>each </em><em>side </em><em>by </em><em>-</em><em>1</em><em> </em><em>:</em>

-c / -1 = -7 / -1

c = 7

  • Let's verify:

2c + 3 ⇔ 2(7) + 3 ⇔ 14 + 3 ⇔ 17

3c - 4 ⇔ 3(7) - 4 ⇔ 21 - 4 ⇔ 17

Therefore, your answer is c = 7 .

In the figure, AA′ = 33 m and BC = 7.5 m. The span is divided into six equal parts at E, G, C, I, and K. Find the length of A′B.
Umnica [9.8K]
The correct answer for the question that is being presented above is this one: "18.12."
The image of this triangle is an isosceles triangle<span> with the base being 33 m (from angle A to angle A') and the right leg is 7.5 m long (BC) the span or width of the triangle is divided by 6 vertical lines with equal distances from each other. so we need to find the length of the left leg AB.</span>

Which graph shows a rate of change of 1/2 which is a fraction between –4 and 0 on the x-axis?
irakobra [83]

By definition, we have that the average rate of change is given by:

AVR = \frac{y2-y1}{x2-x1}

Substituting values we have:

AVR = \frac{3-1}{0-(-4)}

Rewriting we have:

AVR = \frac{2}{0+4}

AVR = \frac{2}{4}

AVR = \frac{1}{2}

Therefore, the graph that has an AVR of 1/2 is the graph of the linear function.

Answer:

graph shows a rate of change of 1/2 is the linear function

Find the relative rate of change fro each of the following functions. f(x)=x^3 -3x^2
Reika [66]
The rate of change is simply the derivative of a function with respect to the other variable. In this case the rate of change with respect to x is desired. Therefore 

f(x) = x^3 - 3x^2
f'(x) = 3x^2 - 6x

therefore the rate of change of y with respect to x is dy/dx = 3x^2 - 6x
