Answer:
y = -3x - 4
Step-by-step explanation:
Find the slope.
y2-y1/x2-x1
-9/3 = -3
-3 is the slope. You know the y-intercept is -4 since (0, -4) is a point. The y-intercept is the value of y where x = 0.
So if you know the slope is -3 and the y-intercept is -4, plug it into slope-intercept form.
y = mx+b
y = -3x - 4

It took a racer 300 second to run 3,000 meters. Based on the ratio given and using a double number line, how long did it take the racer to run 2,000 meters?
(if you can, use a paper to draw the double number line, thank you)
Answer:
200 seconds
1:2 ratio for 2,000 meters and 1:3 ratio for 3,000 meters
Step-by-step explanation:
It takes the racer 100 seconds to run 1,000 meters and there is 3'000 meters so you multiply 100 times 3 to get 300.

Rafiq is makeing a fruit punch using 48 ounces of grape juice abd some seltzer water. He wants to make 10 equal servings that are atleast 9 ounces each. Should he add 32 ounces of seltzer water or 48 ounces of seltzer water
Answer:
48 ounces of seltzer water
Step-by-step explanation:
From the question, we are told that:
Rafiq is making a fruit punch using 48 ounces of grape juice and some seltzer water.
He wants to make 10 equal servings that are at least 9 ounces each.
The total number of ounces that he want so have is at least
= 10 × 9 ounces = 90 ounces
Should he add 32 ounces of seltzer water or 48 ounces of seltzer water?
Let the number of ounces of seltzer water that he wants to add = x
At least = More than or equal to which is represented by inequality sign = ≥
Hence:
48 ounces of grape juice + x ounces of seltzer water ≥ 90 ounces
48 + x ≥ 90
x ≥ 90 - 48
x ≥ 42 ounces of seltzer water
From this calculation, the least amount of seltzer water he can add is 42 ounces.
Therefore, Rafiq should add 48 ounces of seltzer water

Answer:
Garrett gets 36 problems right.
Step-by-step explanation:
Given that,
Total number of MCQs = 60
Correct answers = 60%
We need to find how many problems did Garrett get right. It can be calculated by finding 60% of 60 such that,
[tex]C=\dfrac{60}{100}\times 60\\\\=36[/tex]

An airplane takes 3 hours to travel a distance of 2700 miles with the wind. The return trip takes 5 hours against the wind. Find the speed of the plane in still air and the speed of the wind.
Answer:
720 mph, 180 mphStep-by-step explanation:
Let the speed of the plane is x, speed of the wind is y
Speeds add up when in directions are same and subtract when opposite
Then as per the given we have equations:
3( x + y) = 27005(x - y) = 2700Simplify the equations:
x + y = 900x - y = 540Sum the two equations and solve for x:
2x = 900 + 5402x = 1440x = 720 mphFind the value of y:
y = 720 - 540 = 180 mphSpeed of the plane is 720 mph
Speed of the wind is 180 mph
A house call fee costs $95.
The plumber chargers $125 per hour.
Which one is the slope and which one is the y intercept
Answer:
$95 is the slope
$125 is the y-intercept
Answer:
slope os the 125 per hour and the y intercept is the 95
Step-by-step explanation:
The slope is 125 it will increase by every hour and the y intercept is 95 because it is the starting fee, it will not increase.

PLEASE HELP!!! here are two different strategies to find the new price of a hat after a discount of 40%. The hat was originally $30. Discuss how these strategies are the same and how they are different.
Answer:
Step-by-step explanation:
Method 1: Calculate 40% discount on original price, then subtract discount from original price.
Amount of discount = 40% of $30
= 0.40 × $30
= $12
New price = $30 - $12 = $18
Method 2:
New price = (100% - discount percentage) of original price
= 60% of original price
= 0.60 × $30
= $18
10 sin A + 16 = 3 sin A + 9
Step-by-step explanation:
10 sin A = 3 sin A -7 (subtracting 16 from each side)
10 sin A - 3 sin A = -7 (subtracting 10 sin A from 3 sin A to simplify the equation)
7 sin A = -7 (dividing by 7 to get sin A)
sin A = -1
sin^-1(sin A) = sin^-1(-1) = [tex]\frac{3pi}{2}[/tex] = [tex]-\frac{pi}{2}[/tex](applying the inverse function of sin to cancel sin A to A)
A =[tex]\frac{3pi}{2}[/tex],[tex]-\frac{pi}{2}[/tex]

2.) (0.2)⋅40
3.) (0.25)⋅60
Answer:
1. 150
2. 8
3. 15
Step-by-step explanation:
1. [tex]\frac{3}{4}* \frac{200}{1}[/tex] = [tex]\frac{600}{4}[/tex] = [tex]150[/tex]
2. [tex]0.2 = \frac{1}{5}[/tex]
[tex]\frac{1}{5} * \frac{40}{1}[/tex] = [tex]\frac{40}{5} = 8[/tex]
3. [tex]0.25 = \frac{1}{4}[/tex]
[tex]\frac{1}{4} * \frac{60}{1}[/tex] = [tex]\frac{60}{4} = 15[/tex]

Television sizes are measured on the diagonal Tony's television length is 42 inches and the television width is 31 inches what is the diagonal measurement of Tony's television rounded to the nearest inch
Answer:
52 in approx
Step-by-step explanation:
Given data
Length of TV= 42 in
Widht of TV= 31 in
Required
The diagonal of the TV
Applying the Pythagoras theorem
D^2= L^2+W^2
D= √L^2+W^2
D= √42^2+31^2
D=√1764+961
D=√2725
D=52.20 in
Hence the diagonal of the Tv is 52 in approx
