h(x) = 4x-1
Let x = -3
h(-3) = 4(-3) -1 = -12-1 = -13
Let x = -2
h(-2) = 4(-2) -1 = -8-1 = -9
Let x = 2
h(-2) = 4(2) -1 = 8-1 = 7
Let x = 3
h(3) = 4(3) -1 = 12-1 = 11
Let x = 5
h(5) = 4(5) -1 = 20-1 = 17

linesl,mand n are parallel to each other and p is a transversal
Answers
========================================================
Explanation:
Since L and M are parallel lines, this means x+y = 180 due to the same side interior angles theorem. Some books refer to these angles as consecutive interior angles.
If x+y = 180, then y = 180-x.
Plug this into the equation your teacher gave you
x/y = 3/7
x/(180-x) = 3/7
7x = 3(180-x) ... cross multiply
7x = 540 - 3x
7x+3x = 540
10x = 540
x = 540/10
x = 54
Use this to find y
y = 180-x
y = 180-54
y = 126
Then notice how x/y = 54/126 = 3/7, which helps confirm we have the correct x and y values.
Divide both parts of the first fraction by 18 to fully reduce.
Now because angles y and z are alternate exterior angles, this must mean z = y = 126 degrees
The mass of the sun is 2.13525×10^30 kilograms. The mass of Mercury is 3.285×10^23 kilograms.
How many times greater is the mass of the sun than the mass of Mercury?
Type your answer in scientific notation form.
Answers
Answer:
The mass of Sun is [tex]65\times 10^5[/tex] times greater than mass of Mercury.
Step-by-step explanation:
We are given that
Mass of the sun=[tex]M=2.13525\times 10^{30}[/tex] kg
Mass of Mercury, [tex]m=3.285\times 10^{23}[/tex]kg
We have to find how many times greater is the mass of the sun than the mass of Mercury.
Mass of sun/Mass of mercury=[tex]\frac{2.13525\times 10^{30}}{3.285\times 10^{23}}[/tex]
Mass of sun/Mass of mercury[tex]=0.65\times 10^{30-23}[/tex]
Using the property
[tex]a^x/a^y=a^{x-y}[/tex]
Mass of sun/Mass of mercury[tex]=0.65\times 10^{7}[/tex]
Mass of sun/Mass of mercury[tex]=65\times 10^5[/tex]
Mass of Sun=[tex]65\times 10^5[/tex] times Mass of Mercury
Hence, the mass of Sun is [tex]65\times 10^5[/tex] times greater than mass of Mercury.

A wallpaper store determines that the daily revenue (in pesos) earned by the store on the sale of y square meters of wallpaper is given in the equation R = y2 - 65y. How many square meters of wallpaper must be sold if the revenue from the wallpaper is to be 1200 per day?
Answers
Answer:
1,362, 00
Step-by-step explanation:
R= (1200)2 - 65 (1200)
=1,362,000
80 square meters of wallpaper must be sold.
What is Algebra?Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions. it involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and division to form a meaningful mathematical expression.
Given:
R = y² - 65y.
Now, R= 1200
y² - 65y = 1200
y² - 65y -1200 = 0
y² - 80y + 15y -1200 = 0
(y- 80) (y + 15)= 0
y= 80, -15
Hence, 80 square meters of wallpaper must be sold if the revenue from the wallpaper is to be 1200 per day.

Answers
Answer:
5 hours
Step-by-step explanation:
The charge will be the same when what they pay is equal
100 + 25*number of hours = 50 +35 * number of hours
let number of hours =h
100 + 25h = 50 + 35h, subtract 25 h, and subtract 50 from both sides
100-50 = 35h -25h, combine like terms
50 = 10h , divide by 10 both sides
5 = h , in 5 hours the companies will charge the same amount

In order for the parallelogram to be a rhombus, x=? (7x+13)º
Answers
Answer:
x = 11
Step-by-step explanation:
The diagonals of a rhombus are perpendicular meaning that they create 90 degree angles
If they create 90 degree angles then 7x + 13 = 90
( Note that we've just created an equation that we can use to solve for x )
We now solve for x algebraically using the equation we created
7x + 13 = 90
Step 1 Subtract 13 from both sides
7x = 77
Divide both sides by 7
x = 11

Find the volume of the sphere
Answers
Answer:
7235 using 3.14 for pi
7238 using the pi button
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
V = 4/3 pi (12)^3
V = 2304pi
Letting pi = 3.14
V = 7234.56 and rounding to a whole number
V = 7235
Using the pi button
V =7238.22947 and rounding to a whole number
V = 7238
Answer: 7238
Step-by-step explanation:
The formula used is 4/3πr³
Now let's substitute the radius: 12
4/3πr³
=4/3×π×12³
=4/3×π×1728
=7238.22947
but since we are rounding it to the nearest whole number the answer would be 7238

Answers
The volume of square based pyramid is 4cm³.
What is Square Pyramid ?A square pyramid is a pyramid, in geometry, that has a square base and four lateral faces.
How to find the volume of Square Pyramid ?To find the volume of a pyramid, we multiply the area of its base with the height of the pyramid, and divide by 3.
V=1/ 3×B²×h
where B is the area of the base of the pyramid, and h is its height.
Now in the question,
b = 2cm; h = 3cm
Volume = (1/3 x 2x2x3)cm³
= (1x2x2)cm³
= 4cm³
Therefore, the volume of square based pyramid is 4cm³
