Find the slope of the line parallel to 2x+3y=8
Answers
Answer:
Brandon
Step-by-step explanation:
2x + 3y = 8
-2x -2x
3y = -2x + 8
y = (-2/3)x + 8/3
m = (-2/3)
even tho brandon did not divide 8 by 3, you were just supposed to find the slope of the line parallel to that line so for the most part, he is correct for the way he got his answer
Answer:
slope = - [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x + 3y = 8 ( subtract 2x from both sides )
3y = - 2x + 8 ( divide all terms by 3 )
y = - [tex]\frac{2}{3}[/tex] x + [tex]\frac{8}{3}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{2}{3}[/tex]
Parallel lines have equal slopes , thus
slope of parallel line = - [tex]\frac{2}{3}[/tex]

a. the slope is the cost of one book
b. the slope is the cost if Hana's lunch
c. the y-intercept is the cost of one book
d. the y-intercept is the most if Hana's lunch
Answers
Answer: A and D
Step-by-step explanation:
I took the test online and the answer is A and D the y intercept is the cost of her lunch and the slope is the cost of one book
The true statements are the slope is the cost of one book and the y-intercept is the cost if Hana's lunch.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
as, from the graph the slope tells us about the cost of one book.
Now, From the graph if we talk about y- axis then we can see that the y- axis tells us about cost if Hana's lunch.
Hence, the true statements are the slope is the cost of one book and the y-intercept is the cost if Hana's lunch.

Answers
Answer:
40%
Step-by-step explanation:
12$ out of the original 20$ = 12/20
12/20 = .6 (60%)
1=100%
if 12/20 = 60% then 100% - 60% = 40%

If f(x)=2x^3+4x^2, find f(-3)
Answers
Answer:
f(-3) = -18
Step-by-step explanation:
f(x)=2x^3+4x^2, find f(-3); let's rewrite
f(x) = 2[tex]x^{3}[/tex] + 4[tex]x^{2}[/tex]; substitute -3 for x
f(-3) = 2[tex](-3)^{3}[/tex] + 4[tex](-3)^{2}[/tex]; do the exponents
f(-3) = 2(-27) + 4(9); multiply and add
f(-3) = -54 + 36 = -18
The value of the function f(x) = 2x³ + 4x² at f(-3) is - 18.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, A function f(x) = 2x³ + 4x².
Now, The value of the function f(-3) can be obtained by replacing
x with - 3.
Therefore, f(-3) = 2(-3)³ + 4(-3)².
f(-3) = 2×-27 + 4×9.
f(-3) = - 54 + 36.
f(-3) = - 18.

determine the vertex of y=4(x-25)2+ 91
Answers
Answer:
(25, 91)Step-by-step explanation:
y = a(x - h)² + k ← vertex form of the equation of the parabola with vertex (h, k)
So y = 4(x - 25)² + 91 means:
a = 4
x - 25 = x - h ⇒ - 25 = - h ⇒ h = 25
+ 91 = + k ⇒ k = 91
Therefore vertex is:

9514 1404 393
Answer:
-3/4
Step-by-step explanation:
The given function is a linear function with a slope of -3/4. (The slope is the coefficient of x.) The slope is the rate of change. For a linear function, the slope is the same everywhere. That is, the "average rate of change" and the "rate of change" and the "slope" are all the same value.
Here, the average rate of change is -3/4.
__
Alternate solution
You can compute the average rate of change using the formula ...
average rate of change = (f(x2) -f(x1))/(x2 -x1)
For x1 = -4 and x2 = 0, we need to know the function values:
f(-4) = 10 -(3/4)(-4) = 13
f(0) = 10 -(3/4)(0) = 10
So, the average rate of change formula gives ...
average rate of change = (10 -13)/(0 -(-4)) = -3/4
The average rate of change is -3/4.

On Monday, the temperature was 43°F. On Tuesday, the temperature increased 6°F. On Wednesday, the temperature decreased 13°F. Which integer represents the overall change in temperature from Monday to Wednesday?
Answers
Answer:c Thursday
Step-by-step explanation:
If on Monday, the temperature was 43°F. On Tuesday, the temperature increased by 6°F the overall change in temperature from Monday to Wednesday will be 24°F.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.
It is given that on Monday, the temperature was 43°F. On Tuesday, the temperature increased by 6°F. On Wednesday, the temperature decreased by 13°F.
The overall change in temperature from Monday to Wednesday is found as,
= 43°F + 6°F - 13°F
= 24 °F
Thus, if on Monday, the temperature was 43°F. On Tuesday, the temperature increased by 6°F the overall change in temperature from Monday to Wednesday will be 24°F.
