Answer:

$\Large \boxed{{x =- \frac{5}{2} }}$

Step-by-step explanation:

We need to isolate the $x$ variable on one side of the equation to find the value of $x$ that makes the equation true.

$-10=4x$

Divide both sides of the equation by 4.

$\displaystyle \frac{-10}{4} =\frac{4x}{4}$

Simplify the equation.

$\displaystyle \frac{-5}{2} =x$

Answer:

-2.5 = x

Step-by-step explanation:

-10 = 4x

the equation between 4 and x is multiplication

as our goal is to move the x on its separate side, we should divide each side by 4 to get rid of the bond between the 4 and the x

Therefore,

-10 = 4x

-10/4 = x

Simplify into decimal if needed

-2.5 = x

Hope that helped!!! k

A function is shown: f(x) = (1.07)x What does the function represent? Exponential growth of 7% Exponential decay of 7% Exponenti

tensa zangetsu [6.8K]

Answer:

Exponential growth of 7%

Step-by-step explanation:

We are given the function:

A function is shown: f(x) = (1.07)^x

We can compare this to a formula of Exponential Growth

y = a(1 + r)^x

Hence:

1 + r = 1.07

r = 1.07 - 1

r = 0.07

Converting to percy

0.07 × 100

= 7%

Therefore, the function represents Exponential growth of 7%

Answer:

Then the answer is option a

a. 0<x $\leq$ 10

Step-by-step explanation:

perimeter + height is less than 130 inches.

If height is 60 inches.then perimeter left is 70 inches.

If perimeter was more than 70 inches then perimeter 60 more than the height would be more than 130.

perimeter of rectangle is

It has two widths and two lengths because that's what rectangles do.

width of base "x"

Then the length is 2.5x

perimeter = 2 width + 2 length

= $2(x) + 2(2.5x)$

= 2x + 5x

= 7x

but perimeter can't be more than 70 inches.

So x can't be more than 10 inches because if x was more than 10 inches, then 7x which is perimeter would be more than 70 inches.

$2x + 2(2.5x) + 60 \leq 130$

7x + 60 ≤ 130

7x ≤ 70

x ≤ 10

Then the answer is option a

a. 0<x≤10
