Answer:

Step-by-step explanation:

First, put this equation in slope intercept form.

$y=mx+b$

Where m is the slope and b is the y intercept.

$y+1>2(x-1) \\ \\ y+1>2x-2 \\ \\ y>2x-3$

Since it's greater than, the solution set is above the line, effectively eliminating graph D.

Now we should graph it.

We can see that the point $(2,1)$ is on the graph, and only Graph A has that point. Therefore, Graph A is the correct graph.

Do the ratios 5:3 and 13:8 form a proportion?

shepuryov [24]

Answer:

Step-by-step explanation:

Each ratio is irreducible, and they are different. Hence they are not the same value, so cannot be a proportion. A proportion is two equal ratios.

5 : 3 = 40 : 24

13 : 8 = 39 : 24 . . . . not the same as 40 : 24

_____

<em>Examples of proportions</em>

5/3 = 40/24 . . . is a proportion

13/8 = 39/24 . . . is a proportion

There are 128 students going on a field trip to pan for gold. If they are going in vans that hold 7 students each, how many vans

Viefleur [7K]

128/7 is roughly 18.3 so you would need 19 vans. 18 of them would fit all 7 so you’d have 126 so the last van would fit 2 students meaning it won’t be full

Solve the x <br> 1/3x + 5> 10

kotykmax [81]

Answer:

The solution to the inequality is:

$\frac{1}{3}x+5>10\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x>15\:\\ \:\mathrm{Interval\:Notation:}&\:\left(15,\:\infty \:\right)\end{bmatrix}$

The solution graph is also attached below.

Step-by-step explanation:

Given

We are given the expression

$\frac{1}{3}x+5>10$

To determine

Solve for x

Given the expression

$\frac{1}{3}x+5>10$

Subtract 5 from both sides

$\frac{1}{3}x+5-5>10-5$

Simplify

$\frac{1}{3}x>5$

Multiply both sides by 3

$3\cdot \frac{1}{3}x>5\cdot \:3$

Simplify

$x>15$

Thus, we conclude that:

$x>15$

Therefore, the solution to the inequality is:

$\frac{1}{3}x+5>10\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x>15\:\\ \:\mathrm{Interval\:Notation:}&\:\left(15,\:\infty \:\right)\end{bmatrix}$

The solution graph is also attached below.
