Step-by-step explanation:
'm so sorry :( i dont know if this right tho
Answer:
y = 3x + 7
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 )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (3, 2) ← 2 points on the line
m = [tex]\frac{2-4}{3+3}[/tex] = [tex]\frac{-2}{6}[/tex] = - [tex]\frac{1}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{3} }[/tex] = 3, thus
y = 3x + c ← is the partial equation
To find c substitute (- 1, 4) into the partial equation
4 = - 3 + c ⇒ c = 4 + 3 = 7
y = 3x + 7 ← equation of perpendicular line

46/21 as a decimal rounded to the nearest tenth
Answers
Answer:
2.2
Step-by-step explanation:
46/21 rounded to nearest tenth place is zero.
What is rounding of nos. ?Rounding nos. to nearest places have an advantage that is we could remember the number easily.
For example - 16534 rounded to ten thousand's place is 20000 which is more easier for us to remember and also the number rounded to a certain place retains it's value to about that place.
According to the given question we have to convert the fraction 46/21 as a decimal rounded to the nearest tenth.
We know,
46/21 is
= 2.2 approximately .
Now, if we round 2.2 to the nearest tenth, 2.2 can be written as 02.2.
We observe that it's tenth digit is 0 so when we round it to the nearest tenth place it will be 0.

An electrician earns 100 dollars for a project installing light fixtures. She must pay for the light fixtures herself and they cost 2 dollars and 50 cents each at the hardware store.
Create an equation to represent her profit from the project. Let x represent the number of light fixtures and y represent her total profit (the amount of money she has left over after paying for the light fixtures).
Answers
Answer:
y = 100 - 2.5 x is the equation that represents her total profit from
the project
Step-by-step explanation:
The given is:
1. An electrician earns 100 dollars for a project installing light fixtures
2. She must pay for the light fixtures herself and they cost 2 dollars
and 50 cents each
3. x represent the number of light fixtures and y represent her
total profit
Her profit is the amount of money she has left over after paying for

And your answer is 100% wrong, the correct answer is 30x - 8
now I won't let you down so here it is:
a useful mathematical term(s) is PEMDAS ( Parenthesis, exponent, Multiplication, division, addition, subtraction)
first: the P:
3x(6+4)-2 * 4 >> 3x (10) -2 *4
second: since there are no Exponents you skip to M:
3x(10) - 2 * 4 >> 30x - 8
and done because 30x and 8 are not like terms so this is as far as you go!
Bonus: like terms ex: 8 + 8 or 30x + 30x are like terms so you cant do 30x - 8!

Which function, f(x), can Henry use to determine the area, in square feet, of the first garden?
a f(x) = 48x
O f(x) = 48 - X
f(x) = 48 – x2
d -
f(x) = 48x-x²
Answers
Answer:I’m taking the same quiz rn and am confused
Step-by-step explanation:
The function to represent the area of the garden is f(x) = 48x-x²
What is a function?A function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and range.
Given that, Henry has 96 feet of fencing to enclose the first rectangular garden. The garden will be x feet wide.
Perimeter = 96 feet
Therefore,
2(l+x) = 96
l+x = 48
l = 48-x
Area = lXw
= x(48-x)
= 48x-x²
Hence, The function to represent the area of the garden is f(x) = 48x-x²

find the slope of a line through points (5,-8) and (-2,0)
Answers
this is how: 0-(-8) over -2-5 which is 8 over -7! you always use the format y2-y1 over x2-x1 and you’ll get your answer :)
Answer:
The slope of line through the points (5,-8) and (-2,0) is [tex]-\frac{8}{7}[/tex]
Step-by-step explanation:
Given points are:
(5,-8) and (-2,0)
Slope is the steepness of a straight line.
Slope of the line = m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
We will find the slope of the line through points (5,-8) and (-2,0) by putting values in the formula of slope
Here,
[tex]x_1= 5, y_1=-8\\x_2=-2, y_2=0[/tex]
Slope of the line = [tex]\frac{0-(-8)}{-2-5}[/tex]
Slope of the line = [tex]\frac{8}{-7}=-\frac{8}{7}[/tex]
Hence,
The slope of line through the points (5,-8) and (-2,0) is [tex]-\frac{8}{7}[/tex]
