Which quadratic equation has solutions x=8 and x=−1? clear submit 8x2 7x−1=0 x2 7x−8=0 x2−x 8=0 x2−7x−8=0
The quadratic equation which has solutions x = 8 and x = -1 is [tex]\bold{x^2-7x-8}[/tex] = 0.
An equation of degree 2 is called a quadratic equation. That is, the highest power of x in the equation will be two. It has at most two solutions.
Given the solutions are x = 8 and x = -1.
If x = a is a solution, then (x-a) is a factor for the equation.
So here, x-8 and x+1 are factors of the required quadratic equation.
Thus, the quadratic equation will be, (x-8)(x+1) = [tex]\bold{x^2-7x-8}[/tex] = 0.
We can check if x = 8 and x = -1 are the solutions. Put x = 8 in [tex]\bold{x^2-7x-8}[/tex]
Then, 8 x 8 - 7 x 8 - 8 = 0 and -1 x -1 - 7 x -1 - 8 = 0.
So [tex]\bold{x^2-7x-8}[/tex] = 0 is the quadratic equation with solutions x = 8 and x = -1.

Your friend gave you a free parking pass to a baseball game. Unfortunately, the parking spot number was smudged on the ticket. You know the parking spot was 7 spaces away from your friend's spot. If your friend's parking spot is number 19 in the same row, write and solve and absolute value equation to determine your possible parking spot number(s)? (use \displaystyle xx as the variable to represent the parking spot)
The possible parking spot numbers can be either 12th spot or 26th spot.
What are inequalities ?
When two values are compared , an inequality represents whether one is greater than, less than, or not equal to the other.
It is given that the parking spot was smudged on the ticket.
Let's assume the possible parking spot numbers can be given by x which is represented by an inequality.
Your parking spot is 7 spaces away from your friend's spot which is number 19 in the same row. So , the possible parking spot numbers can be given by ;
19 - 7 ≤ x ≤ 19 + 7
12 ≤ x ≤ 26

What are quadratic in math?
A quadratic in mathematics is a particular kind of problem that involves squaring, or multiplying a variable by itself. This terminology comes from the fact that a square's area equals the product of its side length and itself. Quadratum, the Latin word meaning square, is where the word "quadratic" originates.Use the quadratic formula to find the solutions
x = - b + √b² - 4ac / 2a
Substitute the values

Write an explicit formula for each sequence. Then generate the first five terms. a₁ =1024, r=0.5
The formula of the given geometric sequence is: a(n) = 1024 . (0.5)ⁿ⁻¹ and the first five terms are: 1024, 512, 256, 128, and 64.
The formula of the n-th term of a geometric sequence is:
a(n) = a₁ . r^(n-1)
Where:
a₁ is the first term
r is the ratio = a(n)/a(n-1)
Parameters given in the problem:
a₁ =1024, r=0.5
Plug these parameters into the formula, then we get the explicit formula of the n-th term:
a(n) = 1024 . (0.5)ⁿ⁻¹
The first 5 terms:
a₁ = 1024
a(2) = 1024 . (0.5)²⁻¹
= 1024 . (0.5)¹ = 512
a(3) = 1024 . (0.5)³⁻¹

a(4) = 1024 . (0.5)⁴⁻¹

The measure of one angle on a right triangle is 16° more than the measure of the smallest angle.
find the measures of all three angles
Answer: 37° 53° 90°
Step-by-step explanation:
Given:
ΔABC m∠C=90°
Solution:
m∠A+m∠B+m∠C=180°
m∠A+m∠B+90°=180°
m∠A+m∠B+90°-90°=180°-90°
m∠A+m∠B=90°
Let m∠A=x°
Hence,
m∠B=(x+16)°
Thus,
x°+(x+16)°=90°
(2x)°+16°=90°
(2x)°+16°-16°=90°-16°
(2)(x)°=74°
Divide both parts of the equation by 2:
x°=m∠A=37°
m∠B=37°+16°
m∠B=53°
Zachary purchased a computer for $1,100 on a payment plan. Two months after he purchased the computer, his balance was $870. Six months after he purchased the computer, his balance was $410. What is an equation that models the balance y after x months?
Answer:
y = 1100 - 115x
Step-by-step explanation:
Let the monthly payment be $p
In two months Zach would have paid 2p dollars
Balance would be 1100 - 2p = y
We know after 2 months, balance y was actually 870
Substituting y = 870 we get
1100 - 2p = 870
Subtract 1100 on both sides
1100 - 1100 - 2p = 870 -1100
==> -2p = - 230
Divide by -2 on both sides
-2p/-2 = -230/-2
p = 115 which represents the monthly payment .
So the balance y after m months is given by the equation
y = 1100 - 115x
We can verify by plugging in the values for the second scenario
For 6 months
y = 1100 - 115 x 6 = 1100 - 690 = $410 which agrees with the given value so our equation is consistent

3/4 h -12= 8 5/8 pls answer with a detailed explanation
The value of h based on the information illustrated is 24 1/2.
How to calculate the value?It should be noted that the fraction given is illustrated as:
3/4h - 12 = 8 5/8
Add 12 to both sides
3/4h - 12 + 12 = 8 5/8 + 12
3/4h = 20 5/8
Multiply both side by 4/3
3/4h × 4/3 = 20 5/8 × 4/3
h = 165/8 × 4/3
h = 27 1/2
Therefore, the value of h is 24 1/2.

The numbers in the order of least to greatest is :

Given, the numbers are in decimal and fraction form.
1/2 , -1/4 , 7.2 , 121 , 1.41 , -1.8 , 9.1
we need to convert the fractions and then arrange the numbers in the ascending order.
Writing the numbers in an ordered list according to their values means arranging them from least to greatest. The smallest number should be put on the left, followed by the next smallest number, which should be written directly to its right.
for 1/2:
1/2 = 0.5
for ₋1/4:
₋1/4 = 0.25
now arrange the numbers according to the least to greatest form.

Find a₁ for each arithmetic series.Evaluate S₁₅ for the series 3 x+(3 x-2 y)+(3 x-4 y)+ ......
In the given arithmetic series, the first term is a(1) = 3x and the sum of the first 15 terms is S(15) = 45x - 210y
The given series is:
3x + (3 x-2 y) + (3x-4y) + ......
Notice that this is an arithmetic series with:
the first term, a(1) = 3x
the second term, a(2) = 3x - 2y
the 3rd term, a(3) = 3x - 4y
Hence, the common difference is:
d = (3x - 2y) - 3x = -2y
Recall that the nth term of an arithmetic series is given by:
a(n) = a(1) + (n -1) . d
Substitute n = 15, a(1) = 3x, and d = -2y:
a(15) = 3x + (15 - 1) . (-2y)
a(15) = 3x - 28y
The sum of the first n terms in an arithmetic series is given by:
S(n) = n/2 [a(1) + a(n)]
Substitute n = 15
S(15) = 15/2 [a(1) + a(15)]
S(15) = 15/2 . (3x + 3x - 28y)
S(15) = 15 . (3x - 14y) = 45x - 210y
