Find the x- and y-intercepts of the graph of the equation.
f(x) = 4x – 12
x-intercept
(x, y) =
y-intercept
(x, y) =
Answer:
x intercept is (3, 0). y intercept is (0, -12).
Step-by-step explanation:
x intercept is when y = 0. [f(x) = y] So 0 = 4x - 12. Solving for x gives you a value of 3. [12 = 4x; divide by 4]
y intercept is when x = 0. So y = 4(0) - 12. Solving for y gives you a value of -12. [y= 0 - 12; y = -12]

Trisha uses 3 cups of sugar for every 2 teaspoons of baking soda to make a batch of cookies. Which proportion could be solved to find X, the number of teaspoons of baking soda needed for 9 cups of sugar?
Answer:
Heres how to solve.
Step-by-step explanation:
3 cups of sugar for every 2 teaspoons of baking soda.
So 6 cups of sugar for 4 teaspoons of baking soda.
And 9 cups of sugar for 6 teaspoons of baking soda.
Basically you just multiply by 3, 3×3=9 and 2*3=6
The number of teaspoons of baking soda Trisha needed will be 6.
It is given that Trisha uses 3 cups of sugar for every 2 teaspoon of baking soda.
We have to find out that what will be the number of teaspoons of baking soda needed for 9 cups of sugar.
If a car goes 10 km in two hours , how far will it go in one hour ?
The car will go, 10 ÷ 2 = 5 km in an hour.
As Trisha uses 3 cups of sugar for every 2 teaspoons of baking soda.
For 1 cup of sugar Trisha will have to use 2/3 teaspoons of baking soda .
For 9 cup of sugar Trisha will use ;
= (2/3) × 9 = 18 ÷ 3
= 6
So, Trisha will have to use 6 teaspoons of baking soda for 9 cups of sugar.

Answer:
option 2: [tex]\large \frac{10}{12}[/tex]
Step-by-step explanation:
when dividing fractions, you can actually multiply them together by the reciprocal of the second one. (reciprocal is just flipping the fraction)
so, [tex]\frac{2}{3}[/tex] ÷ [tex]\frac{4}{5}[/tex]
becomes [tex]\frac{2}{3} * \frac{5}{4}[/tex]
to multiply fractions together, just multiply the top and bottom.
2 * 5 = 10
3 * 4 = 12
so the answer would be [tex]\frac{10}{12}[/tex]

You start at (1, -4). You move left 4 units and down 1 unit. Where do you end
The translation of the point (1, -4) when you move left 4 units and down 1 unit will be (0,-8).
What is translation?Translation in mathematics is the movement of a shape in any direction—left, right, up, or down—without turning. They are congruent if the translated shapes (or the image) seem to be the same size as the original shapes. They have only changed their direction or directions.
Given that you start at (1, -4). You move left 4 units and down 1 unit. The translated point will be calculated as,
(1, -4) ⇒ ( 1 - 1 , -4 - 4)
( 1 , 4 ) ⇒ ( 0 , -8)
Therefore, the translation of the point (1, -4) when you move left 4 units and down 1 unit will be (0,-8).

Rebecca’s boss pays her time and a half for overtime work. If her regular wage is $13.50 per hour, what is her overtime rate?
Answer: 20.25
Step-by-step explanation: Rebecca can expect to be making her regular 13.50 an hour, however once time and a half hits she’s looking at taking her 13.50 and dividing it by 2. So 13.50 divided by two is 6.75. You then take that 6.75 and add it on top of her regular 13.50 hourly. Putting you at 20.25 for time and a half.

Anthony has saved $15 of the $140 he needs to purchase a new bicycle. He plans to save $15 each week w, until he has enough money to buy the bicycle. Write an equation to find the number of weeks it will take Anthony to save enough money to buy the bicycle.
Answer:
(140-15)÷15=W
Step-by-step explanation:
140-15=125
125 still needed. divide that by the amount that will be saved each week which is 15 a week and you get 8.3. If they want an actual answer you would say 9 weeks because if you only did 8 Anthony would be short $5 so hed have to wait an additional week to have enough to cover the purchase. So thats why the answer would be 9

An online music store is offering a promotion. When you spend $30 or more, you receive 3 songs for free. You buy an album for $10. Identify an inequality that represents how much more money $m$ you must spend to receive the three free songs.
Answer:
10 + m ≥ 30
You must spend AT MOST $20 or more
Step-by-step explanation:
Basically you have already spent 10 dollars and you have to pay MORE than or equal to 30. You cannot pay less than because you want the free songs. So the sign has to be ≥ or the inequality will not be true.
10 + m ≥ 30
10 - 10 + m ≥ 30 - 10 ( subtract 10 from each side to isolate m)
m ≥ 20 ( we are left with this )
The answer is :
m ≥ 20
You must spend at most 20 dollars more to get the 3 free cd's. Your welcome :D
Which equation is equivalent to the equation 7y + 6 = 34?
Answer:
y = 4
Step-by-step explanation:
You are solving for the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction.
Isolate the variable, y. First, subtract 6 from both sides of the equation:
7y + 6 (-6) = 34 (-6)
7y = 34 - 6
7y = 28
Next, divide 7 from both sides:
(7y)/7 = (28)/7
y = 28/7 = 4
y= 4 is one of the equivalent equations that can answer this question.
