Latoya, Henry, and Manuel served a total of 112 orders Monday at the school cafeteria. Latoya served 7 more orders than Henry. M

Anarel [89]

Answer:

Henry: 21

Latoya: 28

Manuel = 63

Step-by-step explanation:

x = orders henry served

x + 7 = orders latoya served

3x = orders manuel served

x + (x + 7) + 3x = 112

5x + 7 = 112

5x = 105

x = 21

x + 7 = 21 + 7 = 28

3x = 3 * 21 = 63

The slope intercept form for a line is y = mx + b.
↑ ↑

m is the slope of the line or how steep it is. b is where the line runs into the y axis at one point. x and y are the values you plug in when you have a specific point you want to use (x, y).

For the first picture, you can see that the line "intercepts" or collides with the y axis at 1. Thus we know the b value.

To find the slope, you just pick 2 points on the line and plug them into a little equation (try to memorize this equation, it helps to find slope):

m = (y₂ - y₁)/(x₂ - x₁)

The two points we'll use are (1, 0) and (0, 1) since x goes through both of
those points. ↑ ↑ ↑ ↑
x₁ y₁ x₂ y₂

m = (1 - 0)/(0 - 1)

m = 1 / -1

m = -1

This makes sense - since the slope is going downward, the slope is negative.

So the equation is:

y = -x + 1

____________________________________________________________

For the second problem, We can see the line intercepts the y-axis at -5. That is our b value.

The the slope of this line is 0 since it is not going up or down, so that is our m value:

y = 0(x) - 5 = -5

The equation of the line is y = -5

A two-story building measures 21 feet from

allochka39001 [22]

Answer:

<h2>12 inches</h2>

Step-by-step explanation:

Given, 

Measure of a two-story building (in feet)

= 21 feet

So, Measure of the building in (in inches)

= 3 inches

Therefore, 

By the problem, 

21 feet building

= 3 inches

So,

1 feet building

$= \frac{3}{21} inches$

Then,

84 feet building

$= \frac{3}{21} \times 84 \: inches$

= 3 × 4 inches

= 12 inches

Hence,

84 feet building will measure 12 inches (Ans)
