Which expression is equivalent to the given expression?
4(a−3)
A.-8a
B.4a-12
C.4a-3
D.-4(a+3)
Answer:
B. 4a-12
Step-by-step explanation:
First, we can simplify the equation. We use distributive property to remove the 4 and parenthesis.
4a - 12
This is the furthest we can go, meaning the answer is B.
Solve the system of equations - 8x + 3y = -17 and 3x - y = 7 by combining the
equlations.
Given :
Two equations :
-8x + 3y = -17 ....1)
3x - y = 7 ....2)
To Find :
The solution of the system.
Solution :
Multiplying equation 2) by 3 and adding with equation 1), we get :
(-8x + 3y) + 3(3x - y) = -17 + 21
x = 4
Putting above value of x equation 2) we get :
12 - y = 7
y = 5
Therefore, solution of system is ( 4,5 ).
Find the zeros of the function.
Enter the solutions from least to greatest.
f(x)=-3x^2 +75
Answer:
This function doesn't have zeros because it doesn't touch the x-axis.
EDIT: I didn't see the negative sign before the 3. The function crosses the x-axis at (-5,0) and (5,0). Sorry!
Alycia read 20.5 pages of her book in 5 minutes. How many pages did she read in 1 minute?
HELP PLZZ
Answer:
she reads 4 pages per minute hope this helps
Step-by-step explanation:
Answer:
4.1 pages per minute
Step-by-step explanation:
In fraction form we want one minute not five minutes
20.5/5 is what we have but we need x/1
To do this we divide by 5 for the denominator and numerator
20.5/5=4.1
5/5=1
Our answer is 4.1/1 or just 4.1
In ratio form it would be:

Answer:
The new function is g(x) = x² +1
Step-by-step explanation:
Explanation:-
Given that the function f(x) = x²
From graph ,
The parabola y = x² is shifting to up with '1' units
y = x² +1
The new function is g(x) = x² +1
Verification:-
y = x²+1
Put x=0 ⇒ y =1
The point (0,1) lies on the parabola y = x²+1
similarly put x =1 and y = 2
The Point (1,2) lies on the Parabola y = x²+1
∴ The new graph y = x²+1

y is inversely proportional to 7I+x.
When x = 8, y = 2.
Find y when x= 15.
I am taking 7I+x to mean 71+ x.
Answer: y=1.837
Step-by-step explanation:
Step 1
Let y is inversely proportional to 7I+x be mathematically be written as
y ∝ 1/7I+x
Introducing our proportionality of constant , K we have that
y ∝ 1/7I+x
y =K 1/7I+x
y= K/ 7I+xh
Step 2
so when x= 8, and y =2, k becomes
y= K/ 7I+x
k= y x (7I+x)
=2 x (71 + 8)
2x 79
=158
when x= 15, y =?
y= K/ 7I+x
y= 158/ 71 + 15
y=158/86
y=1.837
point j (-8 -12) is reflected over the x axis where is j
Answer:
J(0,2)
Step-by-step explanation:
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.
The new coordinate of the point j' will be (-8, 12).
What is a transformation of a point?A spatial transformation is each mapping of feature space to itself and it maintains some spatial correlation between figures.
It is the image of the point which is located in the opposite direction of a given point.
Point j (-8, -12) is reflected over the x-axis. Then the coordinate of the reflected point j' will be
If the coordinate of a point is (x, y) and it is reflected across the x-axis. Then the coordinate of the reflected point will be (x, -y).
Then the new coordinate of the point j' will be (-8, 12).

2800 is the right answer.A pizzeria uses a 3-pound bag of cheese to make 8 pizzas. Use the given ratio to compute the number of pizzas the pizzeria can make with each number of pounds of cheese.
Answer:
18 pounds = 48 pizzas
18 pounds = 48 pizzas 22.5 pounds = 60 pizzas
18 pounds = 48 pizzas 22.5 pounds = 60 pizzas 27 pounds = 72 pizzas
Step-by-step explanation:
1) because they are ratios you multiply 18 and 8 (18 × 8 = 144) then you divide 144 by 3 (144÷3 =48)
2) now you do the same thing multiply 22.5 and 48 (22.5 × 48= 1,080) and divide 1,080 by 18 (1,080 ÷ 18= 60)
3) multiply 27 times 60 (27 × 60= 1,620) now divide 1,620 by 22.5 (1,620 ÷ 22.5= 72)
The table is:
Cheese Number of Pizzas
3 pounds 8
18 pounds 48
22.5 pounds 60
27 pounds 72
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
3 pounds bag of cheese makes 8 pizzas.
This means,
3 pounds = 8 pizzas
1 pound = 8/3 pizzas
Now,
1 pound = 8/3 pizzas
Multiply 18 on both sides.
18 pounds = 18 x 8/3
18 pounds = 48 pizzas
1 pound = 8/3 pizzas
Multiply 22.5 on both sides.
22.5 pounds = 22.5 x 8/3
22.5 pounds = 60 pizzas
1 pound = 8/3 pizzas
Multiply 27 on both sides.
27 pounds = 27 x 8/3
27 pounds = 72 pizzas
Thus,
The number of Pizzas for 3 pounds is 8.
The number of Pizzas for 18 pounds is 48.
The number of Pizzas for 22.5 pounds is 60.
The number of Pizzas for 27 pounds is 71.

A retail shop is replacing their flooring with new tile. New tile will go in the point shaded area below. Determine the total square feet of tile needed to complete the job.
Answer:
137 ft²
Step-by-step explanation:
The shop is rectangular in shape. The area of a rectangle is given by:
Area = length * width
Since the length of the shop = 20 ft and the width = 10 ft, therefore:
Area of the shop = length * width = 20 ft * 10 ft = 200 ft²
The part that would not be tiled is of triangular shape. The area of a triangle is given as:
Area = (1/2) * base * height
The base of the triangle = 18 ft, the height = 7 ft. Hence:
Area of non tiled part = (1/2) * base * height = (1/2) * 18 ft * 7 ft = 63 ft²
The total square feet of tile needed to complete the job = Area of shop - Area of non tiled part
The total square feet of tile needed to complete the job = 200 ft² - 63 ft² = 137 ft²

therefore, x=47.5°
Answer:
x=21.25
Step-by-step explanation:
The lower two angles will be equal in an isosceles triangle and all angles in a triangle add up to 180 degrees so:
75+(2x+10)+(2x+10)=180
75+4x+20=180

Law of Cosines: c2 = a2 + b2 - 2ab cos C
Answer:
x = 118 degrees approximately
Step-by-step explanation:
Here, we want to get the measure of the angle marked x
We shall use the side facing it and apply the cosine rule
The side facing the angle measures 90
Thus, we have it that;
90^2 = 55^2 + 50^2 - 2(50)(55) cos X
2575 = - -5,500 cos X
X = cos^-1(-2575/5,500)

I need this answer really fast. As soon as possible.
Step-by-step explanation:
Area of Shaded part
= 2 * Area of Quarter-circle - Area of Square
= 0.5π(8)² - 8²
= 32(π - 2)cm².
Perimeter of Shaded part
= 0.5 * 2π(8)
= 8πcm.
The perimeter of the shaded part is 8πcm and the area of the shaded part is 8πcm and 0.5π(8)² - 8² respectively
Perimeter and area of a circleRadius, r = 8 cm
Perimeter of a circle = 2πrPerimeter of s quarter circle = 2πr/4= 1/2πr
Perimeter of Shaded part = 1/2 * 2πr

Answer:
H
Step-by-step explanation:
The answer is H because when is says JKLM is similar to PQRS it is say that the sides JK is equal to PQ, that the side KL is equal to the side QR, that the side LM is equal to RS and the side MJ is equal to SP. When trying to use proportions to find out if a figure is similar to another figure you have to divide a side that is congruent to another side length. For example side QR is congruent to side KL and side PS is congruent to the side JM so if you were to QR/KL it would be equal to PS/JM because the figures are similar if that makes sense.

Bernice monthly paycheck can be represented by p(d) = 21od + 1100. She also earns money babysitting which can be represented by b(d) = 36d + 100. In both functions, d represents the number of weekdays. Write a function, t(d) , that represents Bernice's total monthly income.
Answer:
t(d) = 246d + 1200
Step-by-step explanation:
t(d) = p(d) + b(d)
Where,
t(d) = Bernice's total monthly income
p(d) = monthly paycheck
b(d) = babysitting earnings
d = number of weekdays
p(d) = 210d + 1100
b(d) = 36d + 100
t(d) = p(d) + b(d)
= (210d + 1100) + (36d + 100)
= 210d + 1100 + 36d + 100
= 246d + 1200
t(d) = 246d + 1200
