When rates<span> are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit </span>rates. If you have a multiple-unitrate<span> such as 120 students for every 3 buses, and want to </span>find<span> the single-unit </span>rate<span>, write a ratio equal to the multiple-unit </span>rate<span> with 1 as the second term.</span>

Which point is a solution to the inequality shown in this graph

tiny-mole [99]

Answer: C. (0, -3)

Step-by-step explanation:

You don't even need to find the function, just mentally graph every point in the options on the graph.

If it land in the white area, it's not a solution.
If it land in the blue area or on the line, it's a solution.

<em>The line is not dotted, showing that the inequality is probably either ≥ or ≤, so points on the line do count as solution.</em>

Provide the reflected ordered pair for each of the given ordered pairs. Reflect the ordered pair ( − 4 , 5 ) (-4, 5) across the

levacccp [35]

Answer:

a) (4,5)

b) (0,-3)

Step-by-step explanation:

We have to perform the following reflection over given ordered pair.

a) Reflect the ordered pair (-4,5) across the y-axis

Reflection over y-axis:

$r: (x,y)\rightarrow (-x,y)$

Thus, (-4,5) will be reflected over y-axis as

$r: (-4,5)\rightarrow (-(-4),5) = (4.5)$

b) Reflect the ordered pair (0,3) across the y-axis

Reflection over x-axis:

$r: (x,y)\rightarrow (x,-y)$

Thus, (0,3) will be reflected over x-axis as

$r: (0,3)\rightarrow (0,-(3)) = (0,-3)$

Pls help me! And explain how you found the answer pls

Dmitriy789 [7]

Answer:

y = $\frac{1}{2}$ x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

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

with (x₁, y₁ ) = (- 22, - 14) and (x₂, y₂ ) = (- 18, - 12)

m = $\frac{-12+14}{-18+22}$ = $\frac{2}{4}$ = $\frac{1}{2}$ , thus

y = $\frac{1}{2}$ x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 18, - 12) , then

- 12 = - 9 + c ⇒ c = - 12 + 9 = - 3

y = $\frac{1}{2}$ x - 3 ← equation of line
