Answer:
y = -3/4x - 4
Step-by-step explanation:
Convert the equation to slope intercept form by isolating y
6x + 8y = -32
Subtract 6x from both sides
8y = -6x - 32
Divide each side by 8
y = -6/8x - 4
Simplify -6/8 to -3/4
y = -3/4x - 4
So, the equation in slope intercept form is y = -3/4x - 4

Which ordered pair is the solution of the following
system of equations?
3x + 2y = 4
–2x + 2y = 24
A. (2, -1)
B. (2,-5)
C. (-4,8)
D. (-4,-8)
Answer:
C
Step-by-step explanation:
Given the 2 equations
3x + 2y = 4 → (1)
- 2x + 2y = 24 → (2)
Multiplying (2) by - 1 and adding to (1) will eliminate the y- term
2x - 2y = - 24 → (3)
Add (1) and (3) term by term to eliminate y
5x + 0 = - 20
5x = - 20 ( divide both sides by 5 )
x = - 4
Substitute x = - 4 into either of the 2 equations and solve for y
Substituting into (1)
3(- 4) + 2y = 4
- 12 + 2y = 4 ( add 12 to both sides )
2y = 16 ( divide both sides by 2 )
y = 8
solution is (- 4, 8 ) → C
The sum of four consecutive integers is 238. Find the integers
Answer:
58, 59, 60, 61
Step-by-step explanation:
1st: x-2
2nd: x-1
3rd: x
4th: x+1
Sum = 4x-2 = 238
4x = 240
x = 60
1st: x-2 = 58
2nd: x-1 = 59
3rd; x = 60
4th: x+1 = 61
238/4 = 59.5, the center

Which statements are true about the graph of the function f(x) = x2 – 8x + 5? Select three options.
The function in vertex form is f(x) = (x – 4)2 – 11.
The vertex of the function is (–8, 5).
The axis of symmetry is x = 5.
The y-intercept of the function is (0, 5).
The function crosses the x-axis twice.
The equation is f(x) = x² – 8x + 5. Then the y-intercept is at (0, 5) and the function crosses the x-axis twice. Then the correct options are A, D, and E.
What is the equation of the parabola?Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.
Then the equation of the parabola will be given as,
y = a(x - h)² + k
The quadratic equation is given below.
f(x) = x² – 8x + 5
Convert the equation into vertex form, then the equation will be
f(x) = x² – 8x + 5
f(x) = x² – 8x + 16 – 16 + 5
f(x) = (x – 4)² – 16 + 5
f(x) = (x – 4)² – 11
The graph of the function is given below.
From the graph, the y-intercept is at (0, 5) and the function crosses the x-axis twice.
Then the correct options are A, D, and E.

In a geometric sequence, the first term, a1, is equal to 3, and the fourth term, a4, is equal to 192. Which number represents the common ratio of the geometric sequence?
A. R=4
B. R=6
C. R=5
D. R=7
Plz help me! Before in 7mins.
9514 1404 393
Answer:
A. r = 4
Step-by-step explanation:
For common ratio r, the second term is ...
a2 = 3r
The next terms are ...
a3 = (a2)r = (3r)r = 3r²
a4 = (a3)r = (3r²)r = 3r³ = 192
Then the value of r is ...
r³ = 192/3 = 64
r = ∛64 = 4
The common ratio is r = 4.

What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
Let the equation of graph of the function be represented as A
Now , the value of A is
The function is an exponential equation with intercepts at
Let the first point on the graph be A ( 0 , 5 )
Let the second point on the graph be B ( 1 , 2 )
Now , the line is an exponential decay equation of the form
A = 5 ( 2/5 )ˣ
Therefore , the function is f ( x ) = 5 ( 2/5 )ˣ
Hence , the equation of graph is A = 5 ( 2/5 )ˣ and it is plotted

Step-by-step explanation:
La función es
[tex]f(x)=-70x^2+2800x-45000[/tex]
Diferenciando con respecto a [tex]x[/tex] obtenemos
[tex]f'(x)=-140x+2800[/tex]
Igualar con cero
[tex]0=-140x+2800\\\Rightarrow x=\dfrac{2800}{140}\\\Rightarrow x=20[/tex]

Dr.dre is a dentist. He needs to report on the average number of cavities that his patients have 1,0,5,6,4
Answer:3.2
Step-by-step explanation: add them all up and divide by the sample size.
Answer:
The average number of cavities is 3.2
Step-by-step explanation:
To find the answer we will put them in order from least to greatest.
0, 1, 4, 5, 6. Now add all the numbers up and we get 16. Because we are trying to find the average number, we will count up how many numbers there are. Since their are 5 numbers total, we divide 16 by 5 and we get 3.2. Therefore, 3.2 is our answer.

y = 2x + 35
y = 9x
Answer:
(5,45)
Step-by-step explanation:
Hi,
y = 2x + 35
y = 9x
To solve, we can substitute 9x for y.
9x = 2x + 35
Subtract 2x...
7x = 35
Divide by 7...
x = 5
Now plug in 5 for x...
y = 9x
y = 9(5)
y = 45
Your answer is (5,45)
I hope this helps :)
Answer:
x=5, y=45. (5, 45).
Step-by-step explanation:
y=2x+35
y=9x
-------------
2x+35=9x
35=9x-2x
35=7x
x=35/7
x=5
y=9(5)=45

Subtract 5x from both sides
2x+10−5x=−2
Combine 2x and −5x to get −3x.
−3x+10=−2
Subtract 10 from both sides.
−3x=−12
Divide both sides by −3.
Divide −12 by −3 to get 4.
