Solve the quadratic equation: -x^2+8x=7
Answer:
Step-by-step explanation:
To solve the quadratic equation [tex]-x^2 + 8x = 7[/tex], we first convert it to standard form and identify the coefficients. Using the quadratic formula, we find the solutions to be x = -1 and x = 7.
To solve the given quadratic equation, [tex]-x^2 + 8x = 7[/tex], we first need to bring the equation to the standard form of a quadratic equation, which is [tex]ax^2 + bx + c = 0[/tex]. We can do this by subtracting 7 from both sides, resulting in [tex]-x^2 + 8x - 7 = 0[/tex].
Now the equation is in standard form, we identify the coefficients: a = -1, b = 8, and c = -7. Applying these to the quadratic formula, x = [-b ± [tex]\sqrt(b^2 - 4ac)[/tex]] / (2a), we get:
x = [-8 ± [tex]\sqrt((8)^2[/tex] - 4(-1)(-7))] / [2(-1)]
x = [-8 ± [tex]\sqrt(64 - 28)[/tex]] / -2
x = [-8 ± [tex]\sqrt(36)[/tex]] / -2
x = [-8 ± 6] / -2
Now, solving for x, we get two solutions:
x = (-8 + 6) / -2 = -1
x = (-8 - 6) / -2 = 7
Therefore, the solutions to the quadratic equation are x = -1 and x = 7.

What is the image of (-1,-6) after a reflection over the y-axis?
Answer:
your answer is (1,-6)
Step-by-step explanation:
when a point is reflected in y-axis, then the y-co-ordinate remains same and then x-co-ordinate becomes the opposite of that number.
When you reflect a point across the y-axis, only the x-coordinate changes while the y-coordinate stays the same. For example:
(-x, -y) -> (x, -y)
So:
(-1, -6) -> (1, -6)

What is equation?An equation can be stated as a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
During a recent football season, the relationship between the number of points a team scored and the number of wins a team had is modeled by the equation w equals zero point zero three one p minus three point eight one,
i.e. w = 0.031p - 3.81
where w is the number of wins and p is the number of points scored.
now, we have,
One team in the league scored 444 points and had 12 wins.
i.e. p = 444
w = 12
so, we get,
LHS = 12
and, RHS = 9.954
so, the residual of that team’s win total is,
9.954 - 12
= -2.046
Hence, The solution is, the number that the residual of that team’s win total is, -2.046, i.e. option a. -2.046.

Ross has a spinner that is split into eight equal sections numbered 1 through 8. He spun the spinner 1,104 times. Which of the following would be a good estimate of the number of times the spinner landed on number 6?
A.
291
B.
117
C.
209
D.
127
Answer:
D. 127
Step-by-step explanation:
Because our spinner is split up evenly 8 ways, we a have a 1/8th chance of getting 6 with any given spin. We will want to pick the number that is the closest to one 1/8th of 1104 from our options at the right.
Let's check them one by one. Note that 1/8 as a decimal is .125, if you are using a calculator to do this problem, decimals will be fastest and we'll work with those here.
A) 291/1104 = .264
B) 117/1104 = .106
C) 209/1104 = .189
D) 127/ 1104 = .115
Our closest number to .125 (ie, 1/8th) is .115. or 127 out of 1,104 spins.
Answer:
D, 127
Step-by-step explanation:
it would be d because if the spinners each have equal spots then you can divide it by 8. which gets you 138, but that isn't an option and its probability so its always around a number. so the closest one is 127 or D

The Zamoras rent a storage room that is 10 feet wide, 12 feet long, and
8 feet high. How many cube-shaped boxes 1 foot on each edge can the
Zamoras store in the room?
Answer:
960 cubes
Step-by-step explanation:
To find how many cubes of side 1 foot can be contained in the room, we have to find the volume of the storage room and then, divide by the volume of the cube.
The storage room is in the shape of a rectangular prism, hence, its volume is:
[tex]V = L * W * H[/tex]
where L = length
W = width
H = height
The dimensions of the storage room are:
10 feet wide, 12 feet long, and 8 feet high
Hence, its volume is:
[tex]V = 10 * 12 * 8 = 960 ft^3[/tex]
The volume of the cube of side 1 foot is:
[tex]V = S^3\\\\V = 1^3 = 1 ft^3[/tex]
Hence, the number of cubes that can be contained in the storage room is:
960 / 1 = 960 cubes
960 cubes can be stored in the storage room.

Hudson is blocking off several rooms in a hotel for guests coming to his wedding. The hotel can reserve small rooms that can hold 3 people, and large rooms that can hold 6 people. Hudson booked a total of 19 rooms which can accommodate 87 guests altogether. Write a system of equations that could be used to determine the number of small rooms reserved and the number of large rooms reserved. Define the variables that you use to write the system.
Answer:
Our system is : S + L = 19, and 3S + 6L = 87
Let # of small rooms = S
# of Large rooms = L
10 Large rooms and 9 Small rooms
Step-by-step explanation:
Let # of small rooms = S
# of Large rooms = L
S + L = 19
3*S + 6*L = 87
Our system is : S + L = 19, and 3S + 6L = 87
solve.
S = 19 - L
3*(19 - L) + 6L = 87
57 - 3L + 6L = 87
57 + 3L = 87
3L = 30
L = 10
S = 19 - 10 = 9
Answer:
Step-by-step explanation:
Let the number of smaller rooms be x
Total rooms are 19. So, number of larger rooms = 19 - x
Total guests = 87
3x + (19-x)6 = 87
the largest number which divides 60 and 75 leaving remainders 8 and 10 respectively is
Final answer:
To find the largest number that divides 60 and 75 and leaves remainders of 8 and 10 respectively, the GCD (greatest common divisor) can be used. The GCD between 60 and 8 is 4, and the GCD between 75 and 10 is 5. Thus, the largest number that satisfies the conditions is 4.
Explanation:
To find the largest number that divides 60 and 75 and leaves remainders of 8 and 10 respectively, we can use the concept of the greatest common divisor (GCD). The GCD is the largest number that divides two or more numbers without leaving a remainder. To find the GCD, we can use the Euclidean algorithm.
First, we divide 60 by 8. The quotient is 7 and the remainder is 4. Then, we divide 8 by 4. The quotient is 2 and the remainder is 0. Since the remainder is 0, we stop here. Therefore, the GCD of 60 and 8 is 4.
Next, we divide 75 by 10. The quotient is 7 and the remainder is 5. Then, we divide 10 by 5. The quotient is 2 and the remainder is 0. Again, since the remainder is 0, we stop here. Therefore, the GCD of 75 and 10 is 5.
Therefore, the largest number that divides 60 and 75 and leaves remainders of 8 and 10 respectively is 4.

Linda shoots an arrow at a target in an archery competition. The arc of the arrow can be modeled by the equation y = −0.02x2 + 0.65x + 4, where x is the horizontal distance (in meters) from Linda and y is the height (in meters) of the arrow. How far from Linda does the arrow hit the ground? Round to the nearest tenth.
Answer:
Linda was 37.8 m away when the arrow hit the ground
Step-by-step explanation:
We are given that The arc of the arrow can be modeled by the equation :
[tex]y = -0.02x^2 + 0.65x + 4[/tex]
Where x is the horizontal distance (in meters) from Linda
y is the height (in meters) of the arrow.
Now we are supposed to find How far from Linda does the arrow hit the ground
So, y must be 0 when the arrow hits the ground
So, Substitute y = 0 in the equation :
[tex]y = -0.02x^2 + 0.65x + 4\\0 = -0.02x^2 + 0.65x + 4\\0.02x^2-0.65x-4=0\\0.02(x-37.79)(x+5.29)=0\\x=37.79,-5.29[/tex]
Since distance cannot be negative
So,Linda was 37.8 m away when the arrow hit the ground
