Solution to 2 variable equations 2x+3y=12
Answer:
x= -3/2y + 6
Step-by-step explanation:
Let's solve for x.
2x+3y=12
Step 1: Add -3y to both sides.
2x+3y+−3y=12+−3y
2x=−3y+12
Step 2: Divide both sides by 2.

Find the value of x.
Answer:
x = 5.
Step-by-step explanation:
x is the radius of the circle.
The line of length 4 bisects the chord of length 6 into 2 line segments of length 3.
If we draw a line from the centre to where the chord of length 6 meets the circle we have another radius.
This is also the hypotenuse (h) of a right triangle, so we have a right triangle whose legs are 3 and 4, then:
h^2 = 4^2 + 3^2 = 25
h = 5
x = 5 (as x and h are both radii).
The first term of an arithmetic sequence is 24 and the 19 term is-48. What is the
common difference?
Answer:
common difference d = - 4
Step-by-step explanation:
the nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
given a₁ = 24 and a₁₉ = - 48 , then
24 + 18d = - 48 ( subtract 24 from both sides )
18d = - 72 ( divide both sides by 18 )
d = - 4

given the following equation:
f(x)=(-7)x + -3
Find the following information: f(4) + f(4)
Answer:
-62
Step-by-step explanation:
In this question, we are going to solve the given expression.
We know that our f(x) equation is (-7)x - 3
Since we have to find what f(4) is, we would plug in 4 to x and solve.
Solve:
f(4) = -7(4) - 3
= -28 - 3
= -31
We are not done, we have to plug in our answer to the expression f(4 + f(4), since we now know what the value of f(4) is.
-31 - 31
-62
Your answer would be -62.
HELPPPPPP SOLVE FOR X
Answer:
x = 6
Step-by-step explanation:
These are supplementary angles.
This means that the angles add up to 180 degrees.
The first thing we can do is set 6y equal to 90, because the little red box means that is 90 degrees.
6y = 90
y = 15
Now that we have found y we can solve for x.
Plug in the y to the 5x + 4y
5x + 4(15)
5x + 60
We can set this equal to 90 again
5x + 60 = 90
5x = 30
x = 6
Therefore x is equal to 6.
I hope this helps!!
- Kay :)
Answer:
x= 6
Step-by-step explanation:
Straight line: is equaled to 180 degrees.
6y= 90 (90 divided by 6= 15), so y= 15
5x + 4y= 90 --> 5x + 4(15)= 90 --> 5x + 60= 90 --> 90 - 60= 30 --> 5x= 30 (30 divided by 5= 6), so x= 6
8. Sheila buys two concert tickets from her friend.
She pays $90 for the two tickets. She looks at the
tickets and sees that each ticket has a face value
of $52.50.
B.What was the percent markdown, rounded to the nearest whole percent
Cost of two tickets that Sheila paid to her friend = $ 90
Actual price of 1 ticket = $ 52.50
So, actual price of 2 tickets = 52 x 2 = 105
Hence, markdown or discount Sheila's friend gave her is =
105 - 90 = 15
The answer is $15.
Answer:
15
Step-by-step explanation:
105 - 90 = 15

When given the value of 5/4 hours then in minutes this is equal to 75 minutes.
How to convert hours to minutes?In every hour, there are 60 minutes. If you want to covert hours to minutes therefore, you multiply the number of hours by 60 minutes.
When given the number of hours as 5/4 hours, in minutes this becomes:
= Number of hours x 60 minutes per hour
= 5/4 x 60 minutes per hour
= 300 / 4 minutes
= 75 minutes
In conclusion, the number of minutes in 5/4 hours is equal to 75 minutes.

Chuck Stone is standing atop a high platform. He fires a rock up into the air with his slingshot. While it is in flight, the rock's distance in feet above the ground f(x) is a quadratic equation of time in seconds (x). This situation is modeled by the following function: f(x) = -5x^2 + 40x + 30.
a. How high above the ground is the platform?
30
b. How long does it take for the rock to hit the ground? Show all work to receive full credit!
is 30 correct for a? and please help me with b! Thank you!!!
Answer:
a) the platform is 110 feet above the ground.
b) It takes 8.69 sec for the rock to hit the ground
Step-by-step explanation:
This situation is modelled by the following function: [tex]f(x) = -5x^2 + 40x + 30\\[/tex]
We need to answer the following questions.
a) How high above the ground is the platform?
First we find x using the formula: [tex]x=-\frac{b}{2a}[/tex]
we have b = 40 and a = -5
Putting values and finding x
[tex]x=-\frac{b}{2a}\\x=-\frac{40}{2(-5)}\\x=-\frac{40}{-10}\\x=4[/tex]
Now putting x=4 in the function to find how high above the ground is the platform
[tex]f(x) = -5x^2 + 40x + 30\\Put\:x=4\\f(4)=-5(4)^2+40(4)+30\\f(4)=-5(16)+160+30\\f(4)=-80+160+30\\f(4)=110[/tex]
So, the platform is 110 feet above the ground.
b) How long does it take for the rock to hit the ground? Show all work to receive full credit!
We will factorise the given function [tex]f(x) = -5x^2 + 40x + 30[/tex] to find the time taken to hit the ground.
We can solve the equation using quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
We have a =-5, b=40, c=30
Putting values and finding x
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-40\pm\sqrt{(40)^2-4(-5)(30)}}{2(-5)}\\x=\frac{-40\pm\sqrt{1600+600}}{-10}\\x=\frac{-40\pm\sqrt{2200}}{-10}\\x=\frac{-40\pm46.9}{-10}\\x=\frac{-40+46.9}{-10},x=\frac{-40-46.9}{-10} \\x=-0.69,x=8.69[/tex]
So, we get values of x: x = -0.69 and x=8.69
As time cannot be negative, so we take x=8.69
So, It takes 8.69 sec for the rock to hit the ground

LMN with vertices L(4,8), M(4,3) and N(8,8) is rotated 270 clockwise about the origin what are the coordinates of L’?
Coordinates of L after rotation are (-8,4)
What are the rules of 270 degrees rotation of coordinates about the origin?
Assuming that the rotation is about (0,0)
then after 270° clockwise rotation (x, y) becomes (-y, x)
and after 270° anticlockwise rotation (x, y) becomes (y,-x)
Given that LMN with vertices L(4,8), M(4,3) and N(8,8) is rotated 270° clockwise about the origin
Then for L(4,8) as the rotation is 270° clockwise then
(x, y) = (4,8)
and after 270° clockwise rotation (x, y) becomes (-y, x)
Therefore new coordinates of L are (-8,4)

Answer:
3. 62.5% decrease
4. 26.2% decrease
5. 13.2% decrease
Explanation:
A percentage change is calculated from ...
percent change = ((new value) - (old value))/(old value) × 100%
When it is negative, the change is a decrease.
__
3. (24 -64)/64 × 100% = -40/64 × 100% = -62.5%, a 62.5% decrease
__
4. (4.8 -6.5)/6.5 × 100% = -1.7/6.5 × 100% ≈ -26.2%, a 26.2% decrease
__
5. (1.12 -1.29)/1.29 × 100% = -0.17/1.29 × 100% ≈ -13.2%, a 13.2% decrease
