Answer:

Step-by-step explanation:

Let x represent the mystery number.

Create an equation to represent the situation, then solve for x:

0.85x - 5 = 29

0.85x = 34

x = 40

So, the mystery number is 40.

Answer:

a. (2x - 3)(x - 4)

b. 17 m, 6 m

c. 46 m

Step-by-step explanation:

2x² - 11x + 12 = (2x - 3)(x - 4)

2x - 3 = 2(10) - 3 = 17

x - 4 = 10 - 4 = 6

P = 2L + 2W = 2(17) + 2(6) = 46

Nathan hit 19 homeruns. He scored 3 fewer homeruns than twice the number of homeruns hit by jason. Write and solve an equation t

Vinvika [58]

Jason hit 11 homeruns.

Step-by-step explanation:

Homeruns hit by Nathan = 19

Let,

Homeruns hit by Nathan = x

Homerun hit by Jason = y

According to given statement;

x = 2y - 3 Eqn 1

We know that Nathan hit 19 homeruns, therefore, putting x=19 in Eqn 1

$19=2y-3\\19+3=2y\\22=2y\\2y=22$

Dividing both sides by 2;

$\frac{2y}{2}=\frac{22}{2}\\y=11$

Jason hit 11 homeruns.

What is the rule for the piecewise function shown in the graph?

andrey2020 [161]

The first choice.
The equation of this first line is -2, and since there is an open circle, it is not equal to -3.
The equation of the second line is -x-2, and there is a closed circle, so it includes -3
