Answer:
x = 6
Step-by-step explanation:
For quadratic ax²+bx+c, the axis of symmetry is ...
x = -b/(2a)
Here, you have a=2, b=-24, so ...
x = -(-24)/(2(2)) = 24/4
x = 6 . . . . equation of the axis of symmetry
Two glasses of milk and 3 snack bars have a total of 63 carbohydrates (carbs), and 4 glasses of milk and 2 snack bars have a total of 82 carbs. Determine how many carbs are in one glass of milk and in one snack bar.
Answer:
Glass of milk=15 carbs
One snack bar=11 carbs
Step-by-step explanation:
×2 2m+3s=63.......................1
×1 4m+2s=82..............2
4m+6s=126
4m+2s=82
Cancel out the 4ms
6s=126
2s=82
minus top and bottom equations and remain with
4s= 44
s=44/4
s=11 ∴ one snack bar is 11 carbs
subs s=11 into equation 1
2m+3s=63
2m+3(11)=63
2m+33=63
2m=63-33
2m=30
m=30/2
m=15 ∴one glass of milk is 15 carbs
Solve the system of linear equations by elimination,
-y - 10 = 6x
5x +y = -10
Hey again!
The solution to the given system is (0, -10)
To solve using elimination, we have to add the equations together, and the "y"s will cancel out, and then solve the equations:
5x - 10 = 6x - 10
Now solve.
Add "10" to both sides:
5x = 6x
Subtract "5x" from both sides
0 = x
Now, we plug in the solved "x" value in an equation to solve for "y".
5(0) + y = -10
y = -10
We now know that the solution to the given system is (0, -10)
Hope this helps! Have an amazing day, and remember, you've got this!!
The solution to the given system of linear equations is (0, -10) which is determined by the elimination method.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The system of linear equations is given in the question:
-y - 10 = 6x ....(i)
5x +y = -10 ....(ii)
To solve using elimination, we have to add the equations (i) and (ii) together, and the "y" will be eliminated, and then solve the equations:
⇒ 5x - 10 = 6x - 10
Add "10" to both sides of the above equation
⇒ 5x = 6x
Subtract "5x" from both sides
⇒ 0 = x
⇒ x = 0
Now, substitute the value of x = 0 in equation (ii) to solve for "y".
⇒ 5(0) + y = -10
⇒ y = -10
Therefore, the solution to the given system of linear equations is (0, -10).

A sofa and a love seat together costs S351. The sofa costs double the love seat. How much does the love seat cost?
Round and write your answer to the tenths place value. Do not include units
Answer:
The love seat cost $117.
Step-by-step explanation:
Given that,
A sofa and a love seat together costs $351.
Let love's seat = x
Sofa's seat = 2x
ATQ,
x+2x = $351
3x = $351
[tex]x=\dfrac{351}{3}\\\\x=\$117[/tex]

Answer:
Answer choice D
Step-by-step explanation:
So we need to get r to the right side. First we can multiply by 3 to get rid of the fraction:
3V=4[tex]\pi[/tex][tex]r^{3}[/tex]
Then we can divide both sides by 4[tex]\pi[/tex] to get r by itself:
[tex]\frac{3V}{4\pi } = r^{3}[/tex]
Then cube both sides:
[tex]\sqrt[3]{\frac{3V}{4\pi } } =r\\[/tex]

Sophie had two different coupons for the book store, 15% off coupon or the $2.50 off coupon. The store only allows you to use one coupon at time. The book she wanted was $12. Which is a better coupon for sophie to use and why
Answer:
$2.50 coupon is better as it gives a cheaper sale price.
Step-by-step explanation:
Price of good = $12
Sale price = price of good - coupon
Coupon 1 :
$2.50
Sale price = $12 - $2.50 = 9.50
Coupon 2:
15% off
Sale price =. (100 - 15)% * 12
= 0.85 * 12
= $10.2

14. Two sides of a parallelogram are in the ratio 5 : 3 and its perimeter is 48 cm. Find
the length of each of its sides.
Perimeter of the parallelogram = 2( length + breadth)
Solution :-Let the length and breadth be 5x and 3x
2(5x + 3x) = 48cm
2(8x) = 48cm
x = 48/16
x = 3cm
Length = 5x = 5×3cm = 15cm
Breadth = 3x = 3×3cm = 9cm
We know that,
In parallelogram Opposite sides are equal
Hence, The sides of the Parallelogram are 15cm, 9cm, 15cm and 9cmi do not get this question

If [tex]f(x)=3(x+5)+\frac{4}{x}[/tex] we get [tex]\mathbf{f(a+2)=\frac{3a^2+27a+46}{a+2}}[/tex]
Step-by-step explanation:
We are given the function: [tex]f(x)=3(x+5)+\frac{4}{x}[/tex] we need to find the value of f(a+2)
For finding the value of f(a+2) we will put x= a+2
We have [tex]f(x)=3(x+5)+\frac{4}{x}[/tex]
Put x = a+2
[tex]f(a+2)=3(a+2+5)+\frac{4}{a+2}\\Solving:\\f(a+2)=3(a+7)+\frac{4}{a+2}\\Taking\:LCM\\f(a+2)=\frac{3(a+7)(a+2)+4}{a+2}\\f(a+2)=\frac{3(a^2+2a+7a+14)+4}{a+2}\\f(a+2)=\frac{3(a^2+9a+14)+4}{a+2}\\f(a+2)=\frac{3a^2+27a+42+4}{a+2}\\f(a+2)=\frac{3a^2+27a+46}{a+2}[/tex]
So, If [tex]f(x)=3(x+5)+\frac{4}{x}[/tex] we get [tex]\mathbf{f(a+2)=\frac{3a^2+27a+46}{a+2}}[/tex]

if two angles form a linear pair and the measure of one angle is 47 degrees, what is the measure of the other angle
Step-by-step explanation:
Since we know that as the angles are in linear pair then their sum equals to 180°
Given
One angle = 47°
Let the other angle be x then
x + 47° = 180° {being linear pair }
x = 180° - 47°
Therefore x = 133°
The measure of the other angle is 133°
Hope it will help :)❤
Answer:
133°
Step-by-step explanation:
they form 180° together, so 180-47=133°

Jamie is helping out in the school library. He needs to figure out how many shelves the library staff should order for a new reading corner. There are 378 books for the reading corner. Each shelf holds 50 books. The librarian wants to put all the books on shelves. How many shelves should the library order?
Answer:
8 shelves
Step-by-step explanation:
First do 378 divided by 50 then you when you get your answer (with remaining numbers) you add one more book case so 378 divided by 50 is 7 then you have a remainder 28 so add another shelf which is now 8 shelves!
