Answer:

Here's what I get.

Step-by-step explanation:

To triple this recipe, you must know that

3 × ¼ = ¾

3 × ⅔ = ⁶/₃ = 2

3 × ½ = ³/₂ = 1½

Then the triple recipe will read

\begin{array}{llll}1\frac{3}{4} & \text{cups} & \text{peanut butter}&\\5 & \text{cups} & \text{sugar}& 3 \times 1\frac{2}{3} = 3 + 2\\1\frac{1}{2} & \text{tsp} & \text{salt}&\\7\frac{1}{2}& \text{cups} & \text{flour}& 3 \times 2\frac{1}{2} = 6 + 1\frac{1}{2} \\\,\frac{3}{4} & \text{cup} & \text{butter}&\\4\frac{1}{2} & \text{tsp} & \text{vanilla}&3 \times 1\frac{1}{2} = 3 + 1\frac{1}{2}\\\end{array}

What is the equation of the line that passes through the point (-6, -6) and has a<br> slope of - 1/3
pickupchik [31]

Answer:

The equation of the line is y = -\frac{1}{3}x - 8

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

y = mx + b

In which m is the slope and b is the y-intercept.

Slope of - 1/3

This means that m = -\frac{1}{3}

So

y = -\frac{1}{3}x + b

Through the point (-6, -6)

This means that when x = -6, y = -6. So

y = -\frac{1}{3}x + b

-6 = -\frac{1}{3}(-6) + b

b + 2 = -6

b = -8

The equation of the line is y = -\frac{1}{3}x - 8

What is the equation for the line? enter your answer in the box
Igoryamba
To get the equation of the line, you need two points that belong to this line.
From the given graph, we can choose any two points: (0,-4) and (-2,0)

The general for of the linear straight line is:
y = mx + c where m is the slope and c is the y-intercept

First, we will calculate the slope using the following rule:
slope = (y2-y1) / (x2-x1)
slope (m) = (0--4) / (-2-0) = 4/-2 = -2
The equation of the line now is: y = -2x + c

Then, we will get the value of the c. To do so, we will choose any point and substitute in the equation. I will choose the point (0,-4)
y = -2x + c
-4 = -2(0) + c
c = -4

Based on the above calculations, the equation of the line is:
y = -2x - 4

A diver begins at 140 feet below sea level. She descends at a steady rate of 7 feet per minute for 4.5 minutes. Then, she ascend
Brut [27]

Answer:

Step-by-step explanation:

starting point: 140 feet below sea level.=-140

she then decends= 7(4.5)=31.5

-140-31.5=-171.5

finally she ascends 112.2 feet

-171.5+112.2=-59.3 feet or 59.3 feet below sea level
