Answer:

number = 8

Step-by-step explanation:

Let "number" = x. Set the equation.

"product of 2 and number" = 2(x)

"nine less" = -9

"equal to 7" = "= 7"

2x - 9 = 7

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 9 to both sides.

2x - 9 (+9) = 7 (+9)

2x = 7 (+9)

2x = 16

Divide 2 from both sides.

(2x)/2 = (16)/2

x = 16/2

x = 8

8 is your answer.

There are 3 feet in 1 yard. 300 feet is equal to 100 yards.

2 pieces of rope at 16 yards = 32 yards

1 piece of rope at 12.5 yards = 12.5 yards

1 piece of rope at 123.25 feet, divided by 3 feet per yard = 41.1 yards (approx.)

100 - 32 - 12.5 - 41.1 = 14.4 yards

Now multiply by this number of yards by 3 to convert it to feet.

14.4 x 3 = 43.2 feet

The school club needs 43.2 feet of additional rope.

Solve for x and y<br><br> 2x+7=3y-1
zlopas [31]
To solve for x and y, isolate each variable and simplify your equation:

Solve for x:
2x+7=3y-1 (Subtract 7 on each side)
2x=3y-8 (Divide by 2 on each side)
x=\frac{3y}{2} -4

Solve for y:
2x+7=3y-1
2x+8=3y (Add 1 on each side)
\frac{2x}{3} + \frac{8}{3}=y (Divide by 3)
y=\frac{2x}{3} + \frac{8}{3}

~I hope this helps!~

Which equation could possibly represent the graphed function?
Veseljchak [2.6K]

Answer:

A

Step-by-step explanation:

You're looking for x-intercepts

From the graph you know that the x-intercepts are as follows:

x = -4, x = -2, x = 4

And this is when y or f(x) = 0

so you can rewrite each x-intercept as an equation

0 = x + 4

0 = x + 2

0 = x - 4

Now you know each of the terms

f(x) = (x-4)(x+2)(x+4)
