The equation of a parabola is
y = x² - 6x + 15. Write the equation in vertex form.
Write any numbers as integers or simplified proper or improper fractions.
Answer:
[tex]\displaystyle y = [x - 3]^2 + 6[/tex]
Step-by-step explanation:
Use the method called complete the square, but in this case, we need to take half of the B-term and square the result afterward. Here is how it is done:
[tex]\displaystyle [\frac{b}{2}]^2 \hookrightarrow [\frac{-6}{2}]^2; 9 \\ \\ \boxed{[x - 3]^2} \hookrightarrow x^2 - 6x + 9[/tex]
Now, after you get an equation from using this method, you must follow ONE MORE PROCEDURE, which is figuring the quantity out that when added to 9, you get 15, and that will be 6. So, with that, you have your vertex equation:
[tex]\displaystyle y = A[x - h]^2 + k \\ \\ \boxed{\boxed{y = [x - 3]^2 + 6}}[/tex]
**In the event you have a quadratic equation, if you are asked to locate the vertex, IF factourable, convert the quadratic equation to a vertex equation, where [tex]\displaystyle [h, k][/tex]represents the vertex:
[tex]\displaystyle y = Ax^2 + Bx + C \hookrightarrow y = A[x - h]^2 + k[/tex]

If you run 3 meters per second to the left, where will you be 4 seconds after you pass zero?
Answer:
12 meters to the left, or -12
Step-by-step explanation:
3 meters per second for 4 seconds
Meaning it's 3 x 4
3 x 4 = 12, so therefore it's -12 meters or just 12 meters to the left.
Answer:
12 meters to the left of your starting point.
Step-by-step explanation:
You start at 0 meters. You then start running to the left with an acceleration of 3 m/s to the left. After each seconds, you are 3 more meters to the left.
So
3 m/s * 4 s = 12 m to the left.
Hence, the answer in 12 meters to the left.

a
Answer: x = 5/2 or 2.5
Step-by-step explanation:
1/4x = 5/8
To find the value of X;
We multiply both sides by 4
1/4 x × 4 = 5/8 × 4
x = 5/2 or 2.5
Hey there!
1/4x = -5/8
MULTIPLY 4/1 to BOTH SIDES
4/1 * 1/4x = -5/8 * 4/1
CANCEL out: 4/1 * 1/4 because it give you 1
KEEP: -5/8 * 4/1 because it give you the x-value
NEW EQUATION: x = -5/8 * 4/1
SIMPLIFY IT!
x = -5/2
Therefore, your answer is: x = -5/2

What is the value of x
Answer:
x= 42⁰
Step-by-step explanation:
Keep in mind that they are vertically opposite angles which means they are equal.
2x + 1 = 85⁰
2x = 85⁰-1
2x = 84⁰
Divide it by 2 on both sides.
x = 42⁰
Which pair is equivalent?
How to verify equivalent fractions? If two fractions are equivalent, then the product of one's numerator and the other's denominator is equal to the product of one's denominator and the other numerator. 1 x 12 = 3 x 4. So, 1/3 and 4/12 are equivalent fractions.
What is the area of the semicircle window shown above?
Solution:
We know that the diameter of the semi-circle is 30 inches. Before we use the formula, let's find the radius of the semi-circle.
⇒ Diameter = 2(Radius)
⇒ 30 inches = 2(Radius)
⇒ Radius = 30/2 = 15 inches
The area of the circle is πr², but we need to find the area of the semi-circle. A semi-circle is basically half of a circle. This means that the area of a semi-circle is πr²/2. Now, let's solve for the area of the semi-circle.
⇒ πr²/2 = Area of semi-circle
⇒ (22/7)(15²)/2
⇒ (22/7)(225)/2
⇒ (22/7)(112.5)
⇒ 22/7 × 112.5
⇒ 2475/7 in²
Thus, the area of the semi-circle is 2475/7 in².

Answer:
10
Step-by-step explanation:
Hello! So over here, when they use the word "directly," they're hinting that they want you to use direct proportions.
You know that the mass and the weight directly correlate, which means that they are direct proportions.
We are given a comparison of mass to weight as an example. Mass:Weight = 8:64
If we simplify that ratio, we get 1:8. The ratio of Mass:Weight is 1:8. In other words, the mass is 8 times less than the weight.
We are given our new weight of 80. Since mass is 8 times less than weight, we do 80/8 which equals 10.

what is $262.50 of $3000
Answer: 262.50 is 8.75% of 3000
Step-by-step explanation:
Solution for 262.50 is what percent of 3000:
262.50:3000*100 =
(262.50*100):3000 =
26250:3000 = 8.75
Now we have: 262.50 is what percent of 3000 = 8.75
Question: 262.50 is what percent of 3000?
Percentage solution with steps:
Step 1: We make the assumption that 3000 is 100% since it is our output value.
Step 2: We next represent the value we seek with x
Step 3: From step 1, it follows that 100% = 3000.
Step 4: In the same vein, x% = 262.50 .
Step 5: This gives us a pair of simple equations:
100% = 3000(1).
x% = 262.50(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100%/x% = 262.50%/3000
x = 8.75% Therefore, 262.50 is 8.75% of 3000

brandon took a 50-question exam worth a total of 160 points. There were x two-point questions and y five point questions. How many of each type of question were on the exam?
Answer:
[tex]\large{\boxed{\sf x = 30 , \ y \ = \ 20}}[/tex]
Step-by-step explanation:
Here it is given that Brandon took a 50 question exam worth of 160points . So here the sum of 2 point and 5 point question is 50. So ,
[tex]\sf\qquad\longrightarrow x + y = 50.....(i)[/tex]
Again the maximum marks for the exam is 160 . Therefore ,
[tex]\sf\qquad\longrightarrow 2x + 5y = 160 ..... (ii) [/tex]
Multiply equation (i) with 5 ,
[tex]\sf\qquad\longrightarrow 5x + 5y = 250 [/tex]
Subtract equation (ii) and (i) ,
[tex]\sf\qquad\longrightarrow 5x - 2x = 250-160\\[/tex]
[tex]\sf\qquad\longrightarrow 3x = 90\\[/tex]
[tex]\sf\qquad\longrightarrow x =\dfrac{90}{3}\\[/tex]
[tex]\sf\qquad\longrightarrow \pink{ x = 30} [/tex]
Substitute this value in (i) ,
[tex]\sf\qquad\longrightarrow y = 50-x \\ [/tex]
[tex]\sf\qquad\longrightarrow y= 50-30\\ [/tex]
[tex]\sf\qquad\longrightarrow \pink{ y = 20} [/tex]
Hence ,

10: Find PX
11. Find XQ
12. Find PQ
Answer:
see explanation
Step-by-step explanation:
since X is the midpoint of PQ , then
PX = QX ( substitute values )
4x + 15 = 7x + 6 ( subtract 4x from both sides )
15 = 3x + 6 ( subtract 6 from both sides )
9 = 3x ( divide both sides by 3 )
3 = x
Then
PX = 4x + 15 = 4(3) + 15 = 12 + 15 = 27
XQ = 7x + 6 = 7(3) + 6 = 21 + 6 = 27
PQ = PX + XQ = 27 + 27 = 54
Answer:
PX = 4x + 15 = 4(3) + 15 = 12 + 15 = 27
XQ = 7x + 6 = 7(3) + 6 = 21 + 6 = 27
PQ = PX + XQ = 27 + 27 = 54
Step-by-step explanation:
Since X is the midpoint of PQ , then
PX = QX ( substitute values )
4x + 15 = 7x + 6 ( subtract 4x from both sides )
15 = 3x + 6 ( subtract 6 from both sides )
9 = 3x ( divide both sides by 3 )
3 = x
Then
PX = 4x + 15 = 4(3) + 15 = 12 + 15 = 27
XQ = 7x + 6 = 7(3) + 6 = 21 + 6 = 27
PQ = PX + XQ = 27 + 27 = 54
Hence, the correct answers are: PX = 4x + 15 = 4(3) + 15 = 12 + 15 = 27
XQ = 7x + 6 = 7(3) + 6 = 21 + 6 = 27 PQ = PX + XQ = 27 + 27 = 54
does y-2=2-x have a negative slope
Answer:
Yes

Answer:
Step-by-step explanation:
Let us solve for y and get the equation format y = mx + b where m is the slope's value.

If 0.05 of Eli's cards are baseball cards what fraction of his cards is not baseball cards?
Please write your answer as both a fraction and a decimal.
Answer: 0.95 or 95/100 or 19/20
Step-by-step explanation: Hi there.
To find the fraction, we can subtract 0.05 (number of baseball cards) from 1.00 (all of his cards).
1.00-0.05=0.95
0.95 in fraction form is 95/100, or 19/20 simplified.

0.12, 19/50, 5 out of 12
0.12 (least). 19/50 (second least), and 5 out of 12 (greatest)

If you convert them all to decimals by dividing it will be much easier to solve.
19/50 = 0.38
5 out of 12 is 5/12 = 0.41
