The sign you are missing will determine the completion of the equation. To figure this out, we need to determine what sign will make 730 and 10 equal 7300.
What about addition?
730+10 = 740. Incorrect answer, addition is not applicable.
How about subtraction?
730-10=720. Still incorrect, subtraction is not applicable.
What about multiplication?
730 x 10 = 7300. Yes! Multiplication is the correct sign!
I hope this helps!

Solve the following system of equations. What is one x-value of a solution? f(x)=x^(2)+7x-24 g(x)=-3x-40

Yuki888 [10]

One x- value of the solution is : -2 or -8

<h3>What is an equation?</h3>

An Equation is an algebraic statement that shows that two quantities are equal.

Analysis:

for one x-value of a solution, f(x) = g(x)

$x^{2}$ + 7x -24 = -3x - 40

$x^{2}$ +7x +3x -24 +40 = 0

$x^{2}$ + 10x +16 = 0

$x^{2}$ +8x +2x +16 = 0

x(x+8) +2(x+8) = 0

(x+2)(x+8) = 0

x = -2 or -8

In conclusion, the values of x are -2 or -8

Mrs. Sloan draws two figures on the board.

Trava [24]

A dilated shape will either be enlarged or compressed.

<em>Allen did not make any mistake, and the scale factor is 3.</em>

The dimension of the smaller rectangle (figure Z) is:

3 units by 4 units

The corresponding dimension of the bigger rectangle (figure Z') is:

9 units by 12 units

The scale factor (k) is calculated by dividing the dimensions of Z' by Z.

So, we have:

$k = \frac{9}{3}$

$k = 3$

$k = \frac{12}{4}$

$k = 3$

Notice that both values of k are the same (i.e. 3)

This means that the scale factor is 3

Also figure Z and Z' share the same center of origin at point X

This means that the center of dilation from Z to Z' is X

Hence,

Allen made no mistake, and she is correct about the scale factor.
