y=-1/2x(x-8)
Show steps to put in vertex form
Answer:
y = [tex]\frac{-1}{2}x^{2}[/tex] + 4x + 0
Step-by-step explanation:
y = -1/2x(x-8) (distributive property of equality)
y = -1/2x^2 + 4x + 0
Vertex form : y = ax2 + bx + c
There is no C so you can also represent that by putting a zero so,
y = -1/2x^2 +4x + 0,
Which is the same as,
y = [tex]\frac{-1}{2}x^{2}[/tex] + 4x + 0
exept
less confusing lol.

what is the perpendicular slope of 9x - 5y = 4
Answer:
[tex]\frac{5}{4}[/tex] would be the perpendicular slope.
whoever gets it right will get brainiest! thank you!!
Answer:
Both Tom and Katie
Step-by-step explanation:
When multiplying a whole number by a positive fraction smaller than 1, the answer is always smaller than the original number.
Examples:
5 · [tex]\frac{1}{2}[/tex] = 2 [tex]\frac{1}{2}[/tex] or 2.5
6 · [tex]\frac{3}{4}[/tex] = 4 [tex]\frac{1}{2}[/tex] or 4.5
14 · [tex]\frac{1}{3}[/tex] = 4 [tex]\frac{2}{3}[/tex]
When dividing a whole number by a positive fraction smaller than 1, the answer is always bigger than the original number.
Examples:
5 ÷ [tex]\frac{1}{2}[/tex] = 10
6 ÷ [tex]\frac{3}{4}[/tex] = 8
14 ÷ [tex]\frac{1}{3}[/tex] = 42
hope this helps!
BE||CD. Find the value of x and AC.
Answer:
x = 4.8
AC = 16.8
Step-by-step explanation:
From the picture attached,
In ΔABE and ΔACD
BE║CD, and the AC and AD are the transversal lines.
∠ABE ≅ ∠ACD [Corresponding angles]
∠AEB ≅ ∠ADC [Corresponding angles]
ΔABE ~ ΔACD [By AA property of similarity of two triangles]
And by the property of similar triangles, corresponding sides of the similar triangles are always proportional.
[tex]\frac{\text{AC}}{\text{AB}}=\frac{\text{AD}}{\text{AE}}[/tex]
[tex]\frac{x+12}{12}=\frac{10+4}{10}[/tex]
[tex]\frac{x+12}{12}=\frac{14}{10}[/tex]
10(x + 12) = 12 × 14
10x + 120 = 168
10x = 168 - 120
x = 4.8
AC = x + 4.8
= 12 + 4.8
= 16.8

What is the solution to the following problem??
y=35x
Answer:
Infinite solutions
Answer:hope u understand it better
Step-by-step explanation: y=3
We simplify the equation to the form, which is simple to understand
y=3
We move all terms containing y to the left and all other terms to the right.
+1y=+3
We simplify left and right side of the equation.
+1y=+3
We divide both sides of the equation by 1 to get y.
y=3
Divide using synthetic division, and write a summary statement in fraction form
2x^3+3x^2+4x-10/x + 1
Using synthetic division, a summary statement in fraction form of the polynomial division is; 2x² + x + 3 - (13/(x + 1))
How to use Synthetic Division?
We are given the polynomial fraction as;
(2x³ + 3x² + 4x - 10)/(x + 1)
This means that we want to divide the polynomial (2x³ + 3x² + 4x - 10) by (x + 1) using synthetic division.
For the divisor, we have x + 1, and that means x + 1 = 0, x = -1
So, we'll be using -1 for the synthetic division and we have;
-1 | 2 3 4 -10
× -2 -1 -3
-------------------------
2 1 3 -13
Now we will form the expression in the form of fraction again
2x² + 1.(x) + 3 - 13/(x + 1)

Step-by-step explanation:
But if the answer shown is the correct answer, I think your computer read wrong, because those answers are the exact same :/
Answer:
The answer is 25z^2+2-15z
Step-by-step explanation:
The form one will often see polynomials in is called standard form. It is when the terms are ordered in highest degree to lowest degree. For example, when given the polynomial x4+2x3+x+11, it is in standard form because 4 is the highest power, then 3 and 1.
15-2(7 - x) = 7
(Multi- step equations)
show steps please:)<4
Answer:
3
Step-by-step explanation:
15 - 2(7 - x) = 7
collect like terms
-2(7 - x) = 7 - 15
-2(7 - x) = -8
divide both sides by -2
7 - x = -8/-2
7 - x = 4
collect like terns
-x = 4 - 7
-x = -3
dividing both sides by -
x = 3
Answer:
Step-by-step explanation:
15-2(7-x)=7
15-14+2x=7
1+2x=7

3(x+6)+6x+9=7x+8 Solve for x.*
A -19/2
B 19/2
C 2/19
D -2/19
Answer:
a) -19/2
Step-by-step explanation:
3(x+6)+6x+9=7x+8
3x + 18 + 6x + 9 = 7x + 8
3x + 6x - 7x = 8 - 18 - 9
2x = -19
2x/2 = -19/2
Therefore, x = -19/2

Sean has 9 liters of juice. He pours equal amounts of the juice into 4 pitchers. There is 0.5 of a liter of juice left. How many liters of juice are in each pitcher? Sean has 9 liters of juice. He pours equal amounts of the juice into 4 pitchers. There is 0.5 of a liter of juice left. How many liters of juice are in each pitcher?
Answer:
2.125 liters of juice
Step-by-step explanation:
Total liters of juice = 9
Total liters left = 0.5
Total liters used = Total liters of juice - Total liters left
= 9 - 0.5
= 8.5
Total liters used = 8.5 liters
He pours equal amounts of the juice into 4 pitcher
Liters per pitcher = Total liters used / number of pitchers
= 8.5 / 4
= 2.125 liters
Liters per pitcher = 2.125 liters
Each pitcher has 2.125 liters of juice
