Given the function f (x) = x² + 8x + 7, what are the zeros of f?
Answer:
x = - 7, x = - 1
Step-by-step explanation:
To find the zeros let f(x) = 0 , that is
x² + 8x + 7 = 0
Consider the factors of the constant term (+ 7) which sum to give the coefficient of the x- term (+ 8)
The factors are + 7 and + 1 , since
7 × 1 = + 7 and 7 + 1 = + 8 , then
x² + 8x + 7 = 0
(x + 7)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x + 1 = 0 ⇒ x = - 1

Simplify a^4b^3×a^2b/a^-5b^-2
Answer:
a^11 b^5
Step-by-step explanation:
basically you combine like terms on both sides of the division problem separately
which now becomes a^6b^3/a^-5 b^-2
then you divide which is just subtracting the exponents of like terms
a^(6--5) b^(3--2)
and then solve and you get the answer a^11 b^5

3(4x+6)=x-4
Answer:
x = −2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(4x+6)=x−4
(3)(4x)+(3)(6)=x+−4(Distribute)
12x+18=x+−4
12x+18=x−4
Step 2: Subtract x from both sides.
12x+18−x=x−4−x
11x+18=−4
Step 3: Subtract 18 from both sides.
11x+18−18=−4−18
11x=−22
Step 4: Divide both sides by 11.
[tex]\frac{11x}{11}[/tex] = [tex]\frac{-22}{11}[/tex]
x = −2
Write an equation for the nth term of each arithmetic sequence: 45, 30, 15, 0, …
Answer:
[tex]a_{n}[/tex] = 60 - 15n
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 45 and d = a₂ - a₁ = 30 - 45 = - 15 , then
[tex]a_{n}[/tex] = 45 - 15(n - 1) = 45 - 15n + 15 = 60 - 15n
An equation for the nth term of the arithmetic sequence is aₙ=60-15n.
What is an arithmetic sequence?An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same. The general form an arithmetic sequence is aₙ=a+(n-1)d.
The given arithmetic sequence is 45, 30, 15, 0,.....
Here, a=45 and d=30-45 = -15
Now, aₙ=45+(n-1)(-15)
aₙ=45-15n+15
aₙ=60-15n
Therefore, an equation for the nth term of the arithmetic sequence is aₙ=60-15n.

Someone help Duane scored 55 points in the last basketball game, which is 10 points more than his previous personal best. LeBron scored 15 points more than Chris in the same game. LeBron scored the same number of points as Dwayne‘s previous personal best. Let D represent the number of points Dwayne scored during his previous personal best and C Represent the number of crest points. Question: how many points did Chris score during the game? If these are the only three players who scored, What was the teams totals number of points at the end of the game?
Answer:
130 points
Step-by-step explanation:
Given
[tex]Scorers: Duane,\ LeBron\ \&\ Chris[/tex]
[tex]D=Dwayne[/tex]
[tex]C = Chris[/tex]
[tex]L = LeBron[/tex]
So, we have:
[tex]L = 15 + C[/tex] --- 15 more than Chris
[tex]L =D -10[/tex] --- Same as Dwayne previous personal best
[tex]D = 55[/tex] -- Dwayne's point
Required
Find the total points
We have:
[tex]L = 15 + C[/tex]
[tex]L =D -10[/tex]
[tex]D = 55[/tex]
Substitute [tex]D = 55[/tex] in [tex]L =D -10[/tex]
[tex]L = 55 - 10[/tex]
[tex]L = 45[/tex]
Substitute [tex]L = 45[/tex] in [tex]L = 15 + C[/tex]
[tex]45 = 15 + C[/tex]
[tex]C =45 -15[/tex]
[tex]C =30[/tex]
So, we have:
[tex]D = 55[/tex]
[tex]L = 45[/tex]
[tex]C =30[/tex]
The total points is calculated as:
[tex]Total = D + L + C[/tex]
[tex]Total = 55 + 45 + 30[/tex]
[tex]Total = 130[/tex]

A square has an area of 313.29m2.
Work out the perimeter of the square.
The perimeter of the square is 70.8 meters.
To find the perimeter of a square, we need to know either the length of one side or the area of the square. In this case, we are given the area of the square as 313.29 m².
The formula for the area of a square is:
Area = side length²
We can rearrange this formula to solve for the side length:
Side length = √Area
Substituting the given area into the formula, we have:
Side length = √313.29 m²
Calculating the square root of 313.29, we find that the side length of the square is approximately 17.7 meters (rounded to one decimal place).
Since a square has four equal sides, the perimeter is simply four times the side length:
Perimeter = 4 * 17.7 m = 70.8 meters
As a result, the square's circumference is 70.8 metres.

For numbers 11-16 Find x, y, and z for each. Show all work.
Answer:
x=74
y=37
z=25
Step-by-step explanation:
First, we can find y.
106 and 2y are supplementary angles. That means that when added together, they equal 180.
106+2y=180
2y=74
y=37
We can use this information to help us find x.
x and 2y are corresponding angles, which means that they are congruent.
2y=x
2(37)=x
74=x
Now, let's find z.
4z+6 is corresponding to the angle right above angle x. This means that (4z+6)+x=180.
Let's solve.
(4z+6)+74=180
4z+80=180
4z=100
z=25
Hope this helped!
