Answer:
x=5
Step-by-step explanation:
[tex]4x^2-11=89[/tex]
add 11 to both sides
[tex]4x^2=100[/tex]
Divide 4 on both sides
[tex]x^2=25[/tex]
Take the square root of both sides to eliminate the power of two from x
[tex]\sqrt{x^2} =\sqrt{25}[/tex]
Simplify
[tex]x=5[/tex]

Given that 6x – 5y = 14
Find x when y = 2
Answer:
x = 4
Step-by-step explanation:
Given
6x - 5y = 14 ← substitute y = 2 into the equation
6x - 5(2) = 14
6x - 10 = 14 ( add 10 to both sides )
6x = 24 ( divide both sides by 6 )
x = 4
Answer:
[tex]\huge\boxed{\sf x = 4}[/tex]
Step-by-step explanation:
[tex]\sf 6x-5y = 14\\\\Put \ y = 2\\\\6x - 5(2) = 14\\\\6x - 10 = 14\\\\ Adding \ 10 \ to \ both \ sides\\\\6x = 14+10\\\\6x = 24\\\\Dividing \ both \ sides \ by \ 6\\\\x = 24 / 6\\\\x = 4\\\\\rule[225]{225}{2}[/tex]

Answer:
C) On average, children grow about 9 inches every 2 years.
Step-by-step explanation:
Think about what the slope 9/2 means:
Slope is Change in Y / Change in X which is Change in Height / Change in Age, so 9 inches / 2 years means that on average, children grow about 9 inches every 2 years.

Answer:
to find the total number of miles traveled, you have to add the total distance from point L to point M together. 929+ 595 = 1,524 total miles traveled
to find the average miles per hour, you divide the total miles traveled, by the amount of time it took. 1,524 / 3 = 508 miles per hour
Step-by-step explanation:
Answer:
Step-by-step explanation:
LV to Colorado Springs = 595 miles
Colorado Springs to Mil= 929 miles
Total distance = 1524 miles
Average Speed = 1524 miles / 3 hours
Average Speed = 508 miles / hour

Answer:
XZ ≈ 14.4 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle, that is
cos29° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{YZ}{XZ}[/tex] = [tex]\frac{12.6}{XZ}[/tex] ( multiply both sides by XZ )
XZ × cos29° = 12.6 ( divide both sides by cos29° )
XZ = [tex]\frac{12.6}{cos29}[/tex] ≈ 14.4 cm ( to 3 significant figures )

What is the product in lowest terms? 1/6 • 5/7
Multiply the numerator together and the denominators together.
1 x 5 / 6 . 7 = 5/42
42 is not a multiple of 5 so the answer is already in the lowest term.
The answer is 5/42

Trapezoid JKLM with vertices J(-6, 6), K(-3, 7),
L(-1, 3), and M(-8, 0): (x, y) = (x + 7, y - 3)
Answer:
[tex]J' =(1, 3)[/tex]
[tex]K' = (4,4)[/tex]
[tex]L' = (6,0)[/tex]
[tex]M' = (-1,-3)[/tex]
Step-by-step explanation:
Given
[tex]J = (-6,6)[/tex]
[tex]K = (-3,7)[/tex]
[tex]L= (-1,3)[/tex]
[tex]M = (-8,0)[/tex]
Transformation: [tex](x,y) = (x+7,y-3)[/tex]
This means that, we add 7 to the x coordinate and subtract 3 from the y coordinate.
For J, we have:
[tex]J = (-6,6)[/tex]
[tex]J' =(-6 + 7, 6 - 3)[/tex]
[tex]J' =(1, 3)[/tex]
For K, we have:
[tex]K = (-3,7)[/tex]
[tex]K' = (-3+7,7-3)[/tex]
[tex]K' = (4,4)[/tex]
For L, we have:
[tex]L= (-1,3)[/tex]
[tex]L' = (-1 + 7,3-3)[/tex]
[tex]L' = (6,0)[/tex]
For M, we have:
[tex]M = (-8,0)[/tex]
[tex]M' = (-8+7,0-3)[/tex]
[tex]M' = (-1,-3)[/tex]

For every 3 dozen cookies, a bakery uses 8 cups of butter. How many dozen of cookies could you make with 20 cups of butter?
Answer:
7 1/2 dozen of cookies
Step-by-step explanation:
If for every 3 dozen cookies, a bakery uses 8 cups of butter then we can say;
3 dozens cookies = 8 cups of butter
x cups of cookies = 20 cups of butter
Cross multiply
8*x = 3 * 20
8x = 60
x = 60/8
x = 7 4/8
x = 7 1/2
Hence you will need 7 1/2 dozen of cookies
You want to rent a car for the day.Prestige car rentals charges $47 plus $0.07 per mile to rent a midsize vehicle . Gateway Auto changes a $35 fee plus $0.12 per mile for the same car. For what number of miles will both companies charge the same price?
Answer:
240 miles
Step-by-step explanation:
Given that:
Charges offered by Prestige car rentals for renting a midsize vehicle:
Fixed charges = $47
Per mile charges for renting a midsize vehicle = $0.07
Charges offered by Gateway Auto for renting a midsize vehicle:
Fixed charges = $35
Per mile charges for renting a midsize vehicle = $0.12
To find:
Number of miles for which both the companies charge the same price?
Solution:
Let the number of miles for which both the companies will charge the same price = [tex]x[/tex] miles
Charges for one mile by Prestige car rentals = $0.07
Charges for [tex]x[/tex] miles by Prestige car rentals = $0.07[tex]x[/tex]
Total charges by Prestige Car rentals = $47 + $0.07[tex]x[/tex]
Charges for one mile by Gateway Auto = $0.12
Charges for [tex]x[/tex] miles by Gateway Auto = $0.12[tex]x[/tex]
Total charges by Gateway Auto = $35 + $0.12[tex]x[/tex]
As per question statement, the charges are same:
[tex]\$47 + \$0.07x = \$35 + \$0.12x\\\Rightarrow 12=0.05x\\\Rightarrow x=\dfrac{1200}{5}\\\Rightarrow \bold{x=240\ miles}[/tex]

Solve in quadratic formula
Answer:
I'm sorry I don't know what that means so I just put the meaing for quadratic formula
Step-by-step explanation:
In elementary algebra, the quadratic formula is a formula that provides the solution to a quadratic equation. There are other ways of solving a quadratic equation instead of using the quadratic formula, such as factoring, completing the square, graphing and others
I'm sry that this is not the answer you were probaly looking for but all you said was "Solve in quadratic formula" and theres nothing else so pls if you need to fix that pls do so you can get your answer- Lily~Senpai :P
The graph of a linear relationship passes through (0, 3), and (3, 9). Which is an equation for this linear relationship?
Step-by-step explanation:
1. First calculate for the gradient m
2. Calculate for the constant C by using any point (0,3) or (3,9)
3. Lastly, put the values found in the equation y = mx + c
1. m = Y2-Y1/X2-X1
=9-3/3-0=2
2. input one point together with m into the equation y=mx+c
3=2(0)+C
C=3
3. Therefore equation of linear relationship is
y = 2x + 3
One year after you buy a tree, it is 10 feet tall. Each year after you buy the tree, it grows 2 feet. Write a function that represents the arithmetic sequence (1,10),(2,12),(3,14). How long does it take for the tree to reach its maximum height of 28 feet?
Answer:
10 years
Step-by-step explanation:
We are told that One year after you buy a tree, it is 10 feet tall. Thus, it's initial height after 1 year is 10 ft.
Now we are told that each year after you buy the tree, it grows 2 feet. This means that it's height after you bought it was; f(0) = 10 - 2 = 8ft
Thus,
f(1) = 8 + 2 = 10
f(2) = 8 + 2 + 2 = 12
f(3) = 8 + 2 + 2 + 2 = 14
The pattern here is;
f(x) = 8 + 2x
Where x is number of years
Thus, for it to reach a maximum height of 28 ft;
28 = 8 + 2x
Subtract 8 from both sides to give;
28 - 8 = 2x
2x = 20
x = 20/2
x = 10 years
