Answer:
A
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 )
Here m = - 3 , thus
y = - 3x + c ← is the partial equation
To find c substitute (7, 8) into the partial equation
8 = - 21 + c ⇒ c = 8 + 21 = 29
y = - 3x + 29 → A
Write an equation in slope-intercept form for each table below. Show how you found the slope and y-intercept.
Answer:
y = 2x + 1
Step-by-step explanation:
The intercept is the point where the line touches the y axis. The slope is determined by calculating the rise divided by run.

Step-by-step explanation:
Angle 43 and x are called same-side exterior anglesThat means they sum up to 180 degrees, so[tex]43^{\circ}+x^{\circ}=180^{\circ}\\43^{\circ}-(43^{\circ})+x^{\circ}=180^{\circ}-(43^{\circ})\\x^{\circ}=137^{\circ}[/tex]f ( x ) = 2 ( x − 5 ) − ( 3 x + 1 ) , find f ( − 15 ) ,
Answer:4
Step-by-step explanation:if you replace each "x" in the equation with the given x (-15) then it should go as such:
2(-15-5)-(3(-15)+1)
Then simplify
2(-20)-(-45+1)

2). Arielle has a collection of grasshoppers and crickets. She has 561 insects in all.
The number of grasshoppers is twice the number of crickets. Find the number of
each type of insect that she has
Arielle has 374 grasshoppers and 187 crickets in all.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let's set
x = number of grasshoppers
y = number of crickets
Arielle has a collection of 561 insects, therefore
x + y = 561 [1]
The number of grasshoppers is twice the number of crickets, so
x = 2y [2]
Substituting [2] in [1]:
2y + y = 561
Simplifying
3y = 561
Dividing by 3
y = 561/3
y = 187
From [2]:
x = 374
x = 374
Hence, the number of each type of insect that she has 374 grasshoppers and 187 crickets

Gavin has 50 tokens and continues to ride the roller coaster three times every hour Gibson has 12 tokens and finds two more tokens on the ground every hour how long until they have the same amount of tokens?
Answer:62
Step-by-step explanation: I just did it and got it right
They have the same amount of tokens after t = 7.6 hours.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Since Gavin initially has 50 token and rides the roller coaster three times per hour, he uses 3 token per hour.
So, a number of token he losses after t hours is 3 token per hour × t hours = 3t.
Thus, the number of tokens left after t hours is T = 50 - 3t
Since Gibson initially has 12 tokens and find two tokens on the ground per hour, he gains 2 tokens per hour.
So, number of token he gains after t hours is 2 token per hour × t hours = 2t.
Thus, the number of tokens he has after t hours is T' = 12 + 2t
To find the time t when they will have the same tokens, T must be equal to T', that is T = T'.
So, 50 - 3t = 12 + 2t
Now collecting like terms, we have
50 - 12 = 3t + 2t
38 = 5t
Then dividing both sides by 5, we have
t = 38/5
t = 7.6 hours
Hence, they have the same amount of tokens after t = 7.6 hours.

A recipe uses 5 cups of milk to make 10 servings. If the same amount of milk is used for each serving, how many servings can be made from three quarts? \text{1 gallon}= 1 gallon= \,\,\text{4 quarts} 4 quarts \text{1 quart}= 1 quart= \,\,\text{2 pints} 2 pints \text{1 pint}= 1 pint= \,\,\text{2 cups} 2 cups \text{1 cup}= 1 cup= \,\,\text{8 fluid ounces} 8 fluid ounces Before you try that problem, answer the question below. How many cups will you need to find the number of servings for?
Answer:
24 servings
Step-by-step explanation:
A recipe uses 5 cups of milk to make 10 servings.
We have to carry out some conversions
We have to convert 5 cups to quarts
1 quart = 2 pints
1 pint = 2 cups
Hence, 2 pints = 4 cups
1 quart = 2 cups
1 cup =0.25 quart
5 cups = x quarts
x = 5 × 0.25
x = 1.25 quarts
Hence
1.25 quarts = 10 servings
3 quarts = x
x = 3 × 10/1.25
x = 24 servings

Match each graph with the correct slope of the line. drag and drop the answer
Answer/Step-by-step explanation:
✔️Slope of the first graph:
Using two points on the line, (0, 1) and (3, 2),
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 1}{3 - 0} = \frac{1}{3} [/tex]
Slope = ⅓
✔️Slope of the second graph:
Using two points on the line, (0, 0) and (1, 1),
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 0}{1 - 0} = \frac{1}{1} = 1 [/tex]
Slope = 1
✔️Slope of the third graph:
Using two points on the line, (0, 1) and (2, 2),
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 1}{2 - 0} = \frac{1}{2} [/tex]
Slope = ½
The correct slopes of the graphs are as follows:
1. m = 1 / 3
2. m = 1
3. m = 1 / 2
slope = m = y₂ - y₁ / x₂ - x₁
1.
(0, 1)(6, 3)
m = 3 - 1 / 6 - 0 = 2 / 6 = 1 / 3
2.
(0, 0)(3, 3)
m = 3 - 0 / 3 - 0 = 3 / 3 = 1
3.
(0, 1)(4, 3)
m = 3 - 1 / 4 - 0 = 2 / 4 = 1 /2

The sail and mast of a sailboat form a right triangle.What is the height of the mast on the sailboat? height 20m width 12m
Answer: 16 m
Step-by-step explanation:
Using the Pythagorean theorem you can find the height of the mast.
The formula is;
a² + b² = c²
a is one side of the triangle such as the width
b is another side such as the height
c is the hypotenuse which is the longest side.
c will therefore be 20m.
a will be 12m
12² + b² = 20²
b² = 400 - 144
b² = 256
b = √256
b = 16m
