What can you do to change the vertex form of a quadratic function to standard form?
Step-by-step explanation:
The vertex form of the quadratic equation is: y = a(x - h)² + k.
The standard form of quadratic equation is: y = ax² + bx + c.
In order to change the vertex form into standard form, you'll have to expand the squared binomial, (x - h)² through FOIL method before distributing the value of a, and adding the value of k.
Example:Given the vertex form, y = 2(x - 2)² + 2:
We can transform the given vertex form into its standard form as follows:
Step 1: expand (x - 2)² through FOIL method.(x - 2)² = (x - 2)(x - 2) = x² - 2x - 2x + 4 = x² - 4x + 4.
Step 2: Substitute the trinomial from step 1 into the equation.y = 2(x - 2)² + 2
y = 2(x² - 4x + 4) + 2
Step 3: Distribute 2 into the parenthesis.y = 2(x² - 4x + 4) + 2
y = 2x² - 8x + 8 + 2
Step 4: Combine like terms.y = 2x² - 8x + 10 ⇒ This is the standard form of quadratic equation where a = 2, b = -8, and c = 10.

Jason drew a right triangle with complementary angles that measure (x + 3)° and (x + 9)°. What are the measures of the complementary angles?
A. 44° and 46°
B. 89° and 91°
C. 42° and 48°
D. 51° and 39°
Answer:
C. 42° and 48°
Step-by-step explanation:
Complementary angles: Angles that add up to 90°.
So we can set up an equation..
(x + 3) + (x + 9) = 90
2x + 12 = 90
2x = 78
x = 39°
Now we can find the angles.
Angle 1:
(x + 3)
= 39 + 3
= 42°
Angle 2:
(x + 9)
= 39 + 9
= 48°
And we can check to see if they add to 90°,
42° + 48° = 90°

He can jog 6.25 miles more in 90 minutes than in 40 minutes.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
Given that Jeffrey can jog 5 miles in 40 minutes.
Assume the relationship is proportional and he jogs at a constant rate.
Let x miles can he jog in 90 minutes
According to the given situation, we can write a ratio as
5 miles : 40 minutes = x miles : 90 minutes
⇒ 5 / 40 = x / 90
Apply the cross-multiplication operation,
⇒ 5 × 90 = x × 40
⇒ 450 = 40x
⇒ 40x = 450
Divided by 40 both sides of the equation,
⇒ x = 450/40
Apply the division operation,
⇒ x = 11.25
Thus, the number of miles can he jog in 90 minutes than in 40 minutes will be : 11.25 - 5 = 6.25 miles

find the value of x in the triangle shown below
Answer:
Step-by-step explanation:
Remark
2 of the sides are equal. That means that the two angles opposite the equal sides are equal as well.
Every triangle has 180 degrees
Solution
The unmarked angle = 61 degrees
x + 61 + 61 = 180 The three angles add to 180
x + 122 = 180 Subtract 122 from both sides
x + 122-122 = 180 - 122 Combine
x = 58

Find the circumference and the area of a circle with diameter 7 cm. Use the value 3.14 for n, and do not round your answers. Be sure to include the correct units in your answers.
Answer:
the circumstance would be 21.99
the area is 38.48
Step-by-step explanation:
radius is half the diameter so your radius is 3.5
The area of a circle is pi times the radius squared (A = π r²) which for you would be A = 3.14 × 3.5²
circumference is found by multiplying 2 times pi times the radius (C = 2πr) which for you would be C = 2 × 3.14 × 3.5
What is the value of x in the equation 3x-4y=65, when y=4?
Answer:
3x-4(4) =65
3x-16 =65
3x=65+16
3x=81
x = 27
Step-by-step explanation:
HOPE THAT THIS IS HELPFUL. HAVE A GREAT DAY.
Answer:
x=27
Step-by-step explanation:
since y=4, you just have to plug in 4 for y, then solve.
3x-4y=65
3x-4(4) = 65
3x-16=65
add 16 on both sides
3x=81
dive by 3 on both sides
x=27

Solve for x:
Answer:
7
Step-by-step explanation:
This shape is Kite.
Properties of Kite : -
In Kite, any 1 adjacent side is equal.
So,
5x + 5 = 40
5x = 40 - 5
5x = 35
x = 35 / 5
x = 7
Answer:
x = 7
Step-by-step explanation:
In kite, adjacent sides are congruent.
5x + 5 = 40
Subtract 5 from both sides
5x = 40 - 5
5x = 35
Divide both sides by 5
x = 35/5
x = 7

skater: 12.5 meters in 1 second
cheetah: 26 meters in 1 second
Step-by-step explanation:
To find meters in 1 second (meters per second) divide meters by seconds.
skater: (500 m)/(40 s) = 12.5 m/s . . . . . 12.5 meters in 1 second
cheetah: (260 m)/(10 s) = 26 m/s . . . . . 26 meters in 1 second
twelve less than a number is the same as 5 times the number increased by 4. Find the number
Answer:
The equation I came up with to solve this problem was 12 - x = 5(x +4). By writing my equation that way am I really saying "five times the SUM of a number and 4"? Instead, should the equation be 12 - x = 5x + 4, because the problem reads "fives times the number INCREASED by four
Step-by-step explanation:
x-12=5x+4
