slope =-5, y-intercept =-2
Answer:
y = -5x - 2
Step-by-step explanation:
y = mx + b
m = -5
b = -2
Step-by-step explanation:
I am not completely sure what your question is, but if you want to write an equation, you can just plug in the values for m and b to get y=-5x-2. If you wish to graph it, start at (0,-2) because that is your y-intercept. Next, move up 5 units and to the left 1 unit since the slope is negative. Now you have the point (-1,3). Connect the dots to get the graph.
Which equation is shown in the graph?
Anna made and sold x ceramic vases one week. Her profit, P, in dollars is calculated using the formula P = R - C . Where R represents her revenue and C represents her costs. If R = 25x - 0.5x ^ 2 C = 100 + 5x which expression represents her profit in dollars?
Answer:
-0.5x² + 20x + 100
Step-by-step explanation:
Given:
R = 25x - 0.5x²
C = 100 + 5x
P = R - C
Where,
P = profits
R = Revenue
C = Cost
which expression represents her profit in dollars?
P = R - C
R = 25x - 0.5x²
C = 100 + 5x
= 25x - 0.5x² -(-100 + 5x )
= 25x - 0.5x² + 100 - 5x
= -0.5x² + 20x + 100
The expression which represents her profit in dollars is -0.5x² + 20x + 100
A bakery sells mocha cupcakes and chocolate cupcakes. One day it sold 28 mocha and
52 chocolate. What percent of the cupcakes sold that day were mocha?
Answer:
35% of the cupcakes were Mocha.
Step-by-step explanation:
So, 28 + 52 = 80 which means the question is: 28 is what percent % of 80? And 28 is 35% of 80. Hope I helped! Sorry if not. Have a wonderful day and an even better Christmas break! Remwmber to focus on the positive and give me a follow! ;) Bye!

A ball is thrown from the top row of seats in a stadium. The function h(t)=-16t2+48t+160 gives the height, t, in feet, of the ball t seconds after it is thrown. How long will it be before the ball hits the ground?
Answer:
t = 5 s
Step-by-step explanation:
The function that gives the height in feet of the ball t seconds after it is thrown is :
[tex]h(t)=-16t^2+48t+160[/tex]
We need to find how long will it be before the ball hits the ground. When it hits the ground, its height will be equal to 0.
So,
[tex]-16t^2+48t+160=0[/tex]
We need to solve this equation. When we solve, we get its solution as shown in the figure. We can see that t = -2 s and t = 5 s.
t = -2 s is not possible.
Hence, the ball will hit the ground before 5 seconds.

Joanne was hired by a florist to make large boes for holidays wreaths each roll of ribbon has 20 yards joanne used 3 1/2 rolls of ribbons to make 15 bows how many feet of ribbon did she use to make each bow
Answer: Each bow needs 4.67 yards of ribbon.
Step-by-step explanation:
We know that each roll has 20 yd.
She used 3 + 1/2 rolls, then the total length used will be (3 + 1/2) times the length of each roll, this is:
(3 + 1/2)*20 yd = (6/2 + 1/2)*20yd = (7/2)*20yd = 70 yd.
With tose 70 yards of ribbon, she made 15 bows, then the length of ribbon used in each bow will be equal to the quotient between the total length used and the number of ribbons made with it, this is:
70yd/15 = 4.67 yards
Each bow needs 4.67 yards of ribbon.

Jody has 4 red marbles, 6 blue marbles, and 9 yellow marbles. What is the ratio of red marbles to blue marbles?
Answer:
2:3
Step-by-step explanation:
First, create the ratio by putting the numbers together:
There are 4 red and 6 blue marbles:
4:6
Since both of these are divisible by 2, it can be simplified:
4:6
2:3
So, the ratio of red marbles to blue marbles is 2:3
Answer: 4 to 6 marbles

ANSWER ASAP PLZ Which expression is equivalent to 24 + 64?
8(3 + 64)
8(16 + 56)
8(3 + 8)
8(16 + 64)
Answer:
8(3+8)
Step-by-step explanation:
24+64=88
Now you have to find which expression equals 88.
8(3+64)=8x3+8x64=24+512=536
8(16+56)=8x16+8x56=128+448=576
8(3+8)=8x3+8x8=24+64=88
Therefore, 8(3+8) is correct.
Answer:
C
Step-by-step explanation:
8+3 is 11 and 11 x8 is 88 and 24 + 64 is 88

the opposite of 5x and 5x+8?
the opposite or addictive increase of 5x is -5x.
the opposite or addictive increase of 5x + 8 is -5x -8.
Answer:
Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x5+85 f - 1 ( x ) = x 5 + 8 5 is the inverse of f(x)=5x−8 f ( x ) = 5 x - 8 .

A recipe for blueberry muffins states that it yields 12 muffins, with 270 calories per muffin. You instead decide to make
mini-muffins, and the recipe yields 20 mini-muffins. If you eat 7 mini-muffins, how many calories will you consume?
Answer:
If you eat 7 mini-muffins, will you consume 1134 calories.
Step-by-step explanation:
A recipe for blueberry muffins states that it yields 12 muffins, with 270 calories per muffin.
i.e.
No of muffins = 12 muffinsCalories per muffin = 270 caloriesTotal calories of standard muffins = 270 × 12 = 3240 calories
If the same amount of calories are made by 20 mini-muffins, then the total number of calories per mini-muffin will be:
3240/20 = [tex]162[/tex] calories per muffin
As you ate 7 mini-muffins.
Thus,
Your eaten calories = 162 × 7 ∵ 162 calories per muffin
= 1134 calories
Therefore, if you eat 7 mini-muffins, will you consume 1134 calories.

Hello!
Answer:[tex]\boxed{ \bf x=6}[/tex]
Explanation:3(x + 3) = 18
⇒ Step 1 - Multiply everything in the brackets by 3:
3x + 9 = 18
⇒ Step 2 - Subtract 9 from both sides of the equation:
3x + 9 = 18
- 9 - 9
3x = 18
⇒ Step 3 - Divide both sides of the equation by 3.
[tex]\frac{3x}{3} = \frac{18}{3}[/tex]
x = 6
Answer: x = 3
Step-by-step explanation:
1. Distribute.
3(x+3)=183x+9=182. Subtract 9 from BOTH sides.
3x+9-9=18-93. Simplify.
Subtract 9 from BOTH sides.3x=9 is the answer.4. Divide BOTH sides of the equation by the same term.
[tex]\frac{3x}{3} =\frac{9}{3}[/tex]5. Simplify.
Cancel out the terms that are both in the numerator and the denominator.Divide the numbers.Therefore, your answer is X = 3
