What is an equation of the line that passes through the points (5, -3) and
(-3, -3)?
Answer:
y= - 3
Step-by-step explanation:
note that the y- coordinates of both points are - 3
This indicates the line passing through them is a horizontal line, parallel to the x- axis with equation
y = c ( c is the value of the y- coordinates the line passes through ), that is
y = - 3

Right triangular prism. Each base is a right triangle such that the sides forming the right angle are labeled 7 m and 24 m, and the remaining side is labeled 25 m. The distance between the bases is 20 m.
The surface area of the right triangular prism shown is 1288 m²
What is an area?
Area is the amount of space occupied by a two dimensional shape or object.
The prism has a triangular base with 24 m and height of 7m..
The surface area of the prism = 2(0.5 * 24 * 7) + (25 * 20) + (20 * 7) + (24 * 20) = 1288 m²

ห - 14W - 32
I’m factoring polynomials please help
Answer:
Step-by-step explanation:
Sum = -14
Product = - 32
So, the factors = -16 , 2
When we add -16 +2 = -12 and when we multiply it is -32
w⁴ - 14w² - 32 = w⁴ - 16w² + 2w² - 16 * 2
= w²(w² - 16) + 2(w² - 16)
= (w² - 16)(w² + 2)
= (w² - 4²)(w² + 2)
= (w + 4)(w - 4)(w² + 2)
Step-by-step explanation:
Replace w^2 with any other variable for eg: w^2=a
so that will make the equation:
a^2-14a-32
now factorize this equation and u can find the value of a
a^2-16a+2a-32
a(a-16)+2(a-16)
so factors= (a+2) (a-16)
since a was w^2 so replace them with w^2 and u got factors of the equation
you can also directly factorize the whole equation through middle term breaking
w^4-16w^2+2w^2-32
w^2(w^2-16)+2(w^2-16)
(w^2+2)(w^2-16)
you get the same answer

5: just do 4/5 and you get .8 which is 80%
6: just do 16/50 and you get .32 which is 32%

copies in Rs. 5760? Also how much profit in percent did he get in the business of
copy? Find it.
Answer:
30%
Step-by-step explanation:
4320 - 288 = 4032
4032/12 =336 per copies
So, he sold them in 5760
5760 - 4032 = 1728
(1728/5760)*100 = 30%

Find the measure of angle x in the figure.
Note: Angles not drawn to scale.
Angle x measures=
Answer:
x = 125°
Step-by-step explanation:
There are 7 angles in this shape. The sum of the angles in a shape like this is calculated using a formula.
Total of angles
= (n - 2)•180°
Put in 7, because there are 7 angles.
= (7 - 2)•180°
= 5•180°
= 900°
So the total of the angles should be 900°. We know all of the angles except one.
900° = 123°+129°+128°+128°+132°+135°+ x
900° = 775° + x
Subtract 775.
125° = x
The missing angle is 125°.

Cameron wants to buy a new bike that costs $112. He is saving $8 per week. How many weeks will it be until Cameron has all the money he needs to buy the
bike
the answer is 14
Step-by-step explanation:
Need help ASAP please
Part 1:
You started saving for a car when you were in middle school. You have done some research and discovered that it will cost you about $9,500 for a used car that would fit your needs. You were encouraged to invest some of your savings to help you get to your financial goal faster. So far you have saved $7,500. If you invest this money in a savings account with a 3.3% interest rate compounded annually, how long will it take to earn enough money to go purchase the car? Use the compound interest formula A = P (1 + i)n, where A is the accumulated amount, P is the principal, i is the interest rate per year, and n is the number of years. Round your final answer to the nearest tenth.
Answer:
7.3 years.
Step-by-step explanation:
A = P(1 + i)^n
9500 = 7500(1 + 0.033)^n where n = number of years.
1.033^n = 9500/7500
n log 1.033 = log(9500/7500)
n = log(9500/7500)/log 1.033
n = 7.28 = 7.3.

Which of the following is the equation for the line perpendicular to the line 3x -2y =10 that passes through the point (7,5)?
A. Y = 2/3x + 29/3
B. Y = -2/3x + 1/3
C. Y = 2/3x + 1/3
D. Y = -2/3x + 29/3
The equation of the perpendicular line will be y = 29 / 3 - (2/3)x. Then the correct option is D.
What is the equation of a perpendicular line?Let the equation of the line be ax + by + c = 0. Then the equation of the perpendicular line that is perpendicular to the line ax + by + c = 0 is given as bx - ay + d = 0. If the slope of the line is m, then the slope of the perpendicular line will be negative 1/m.
The equation of the line is given below.
3x - 2y = 10
The equation of the line that is perpendicular line is given as,
2x + 3y + d = 0
The equation is passing through (7, 5). Then we have
2(7) + 3(5) + d = 0
14 + 15 + d = 0
29 + d = 0
d = - 29
Then the equation of the line is given as,
2x + 3y - 29 = 0
2x + 3y = 29
3y = 29 - 2x
y = 29 / 3 - (2/3)x
The equation of the perpendicular line will be y = 29 / 3 - (2/3)x. Then the correct option is D.

Answer:
Step-by-step explanation:
1. Write an equation to find the number of toppings, x, when you would pay for the same amount for Pizza A and B.
So, we have to make a relationship between Pizza A and Pizza B, and this is talking about the pizza and toppings so,
$10 + $1.50x = $12.50 + $1.00x
Now we solve for the x values and the starting amount of money,
0.50x = 2.50
and that gives us,
$5
The answer also solves for the bottom one, the answer you need on the top one is,
$10 + $1.50x = $12.50 + $1.00x

Group of answer choices: A, Billy's soccer team won 17 games which represents 85% of their games.
B, Sam's soccer team won 9 games which represents 3/4 pf their games.
C, Both of their teams lost 3 games, so their losing percentage would be the same.
D,Sam's soccer team lost 3 games which represents 25% of their games.
