Answer:

infinitely many

Step-by-step explanation:

30x+60y=800

let 60y=800-30x

then:

30x+800-30x=800

0=0

infinitely many- unless you want to factor it instead of solving

Deion divided 1/2 of a liter of plant fertilizer evenly among some smaller bottles. He put 1/8 of a liter into each bottle. How

Klio2033 [76]

Answer:

4 bottles

Step-by-step explanation:

Given

$Fertilizer = \frac{1}{2}L$

$Bottles = \frac{1}{8}L$

Required

Determine the number of bottles

Represent the number of bottles with N

This implies that N bottles of $\frac{1}{8}L$ fit into $\frac{1}{2}L$ of fertilizer. The relationship between them is:

$Fertilizer = Bottles * N$

$\frac{1}{2}L = \frac{1}{8}L* N$

$\frac{1}{2} = \frac{1}{8}* N$

Multiply through by 8

$8 * \frac{1}{2} = 8 * \frac{1}{8}* N$

$4 = 1* N$

$4 = N$

$N = 4$

Hence, there are N = 4

Which of the following is most likely the next step in the series

Phantasy [73]

Answer:

Step-by-step explanation:

In this series we see that an extra two dots (one on the top, one on the bottom of the same column) are being added on the left side.

-> It starts out at 3

-> Next it becomes 5, with the extra two on the left side

-> Now it is 7, with the last set of extra two also on the left side

Using this logic, we can infer that the most likely answer will be A.

Have a nice day!

On a coordinate plane, 2 straight lines are shown. The first solid line has a positive slope and goes through (0, negative 2) an

ExtremeBDS [4]

Answer:

$y\geq x-2$

$x+2y$

Step-by-step explanation:

step 1

Find the equation of the first inequality

Find the equation of the first solid line

we have the ordered pairs

(0,-2) and (2,0)

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{0+2}{2-0}$

$m=\frac{2}{2}$

$m=1$

The equation in slope intercept form is equal to

$y=mx+b$

we have

$m=1$

$b=-2$ ---> the y-intercept is given

substitute

$y=x-2$

Remember that

Everything to the left of the solid line is shaded

The inequality is

$y\geq x-2$

step 2

Find the equation of the second inequality

Find the equation of the second dashed line

we have the ordered pairs

(0,2) and (4,0)

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{0-2}{4-0}$

$m=\frac{-2}{4}$

$m=-\frac{1}{2}$

The equation in slope intercept form is equal to

$y=mx+b$

we have

$m=-\frac{1}{2}$

$b=2$ ---> the y-intercept is given

substitute

$y=-\frac{1}{2}x+2$

Remember that

Everything below and to the left of the line is shaded

The inequality is

$y$

Rewrite

Multiply by 2 both sides

$2y$

$x+2y$

therefore

The system of inequalities is

$y\geq x-2$

$x+2y$

see the attached figure to better understand the problem

a student found the slope of a line that passes through the points (1,14) and (3,4) to be 5. what mistake did she make?

SSSSS [86.1K]

M = (y2-y1)/(x2-x1)
= (4-14)/3-1
= -10/2
= -5

Rita earns $17.00 per hour. If she gets a 6% raise, what will be her new hourly wage?

ipn [44]

multiply 17 by 6%

17 * 0.06 = 1.02 increase

17 +1.02 = 18.02 new hourly wage
