Expand:

-3x - 9 = -3x - 3 - 5

Simplify:

-3x - 9 = -3x - 8

Add 3x to both sides:

-9 = -8

THERE IS NO VALUE FOR X THAT MAKES THIS EQUATION TRUE

Sally’s parents deposited $15,000 into a college savings account on her third birthday. The account had an interest rate of 9.6%

oee [108]

Rule of 72 says to divide 72 by the rate of return and that will be the number of years an investment will double
so 72 / 9.6 = 7.5 years to double

7.5 * 2 = 15 years

18-3 = 15

the answer is: <span>Yes, the $15,000 will double each 7.5 years. In 15 years, it will double twice.</span>

Answer:

$y=\frac{13}{6}x$ $y= \frac{11}{5}x$ $y = \frac{21}{9}x$ $y = \frac{19}{8}x$

Step-by-step explanation:

Given

The attached graph

Required

Equations with higher unit rate

First, calculate the unit rate of the graph

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Where:

$(x_1.y_1) = (0,0)$

$(x_2.y_2) = (7,15)$

So:

$m = \frac{15 - 0}{7 - 0}$

$m = \frac{15}{7}$

$m = 2.143$

For the given options.

The unit rate is the coefficient of x

So: $y = \frac{19}{8}x$

Going by the above definition of unit rate.

$m = \frac{19}{8}$

$m = 2.375$

$y = \frac{27}{13}x$

$m = \frac{27}{13}$

$m = 2.077$

$y = \frac{21}{9}x$

$m = \frac{21}{9}$

$m = 2.333$

$y= \frac{11}{5}x$

$m= \frac{11}{5}$

$m= 2.20$

$y = \frac{15}{7}x$

$m = \frac{15}{7}$

$m = 2.143$

$y = \frac{31}{15}x$

$m = \frac{31}{15}$

$y = 2.067$

$y=\frac{13}{6}x$

$m=\frac{13}{6}$

$m=2.167$

The unit rates grater than the graph's from small to large are:

$y=\frac{13}{6}x$ $y= \frac{11}{5}x$ $y = \frac{21}{9}x$ $y = \frac{19}{8}x$

$m=\frac{13}{6}$ $m= \frac{11}{5}$ $m = \frac{21}{9}$ $m = \frac{19}{8}$

Axis of symmetry for f(x) = -2x2 + 20x -42

Ksenya-84 [330]

For the function $f(x)=2x^2 +20x-42$

We can use the formula for the axis of symetry, which is $x= \frac{-b}{2a}$

With the values substituted, we get...

$\frac{-20}{2(-2)} =5$

Therefore the axis of symmetry is $x=5$

the volume of a cube depends on the length of its sides.this can be written in function notation as v(s). what is the best inter

Sergeeva-Olga [200]

<u>Answer:</u>

Interpretation: A cube with sides of 4 units each has a volume of 64 units³.

<u>Explanation:</u>

As v(s) represents the volume of the cube, s represents the length of the sides.

∴ v(4) represents the volume of a cube with sides of units, and the volume is 64 units³
