Answer: y = (1/3)*x - 7
Step-by-step explanation:
When we have a line:
y = a*x + b
A perpendicular line to this one needs to have a slope s equal to:
s = -(1/a)
Then any line written as:
y = -(1/a)*x + c
is perpendicular to the lines of the form "y = a*x + b"
Then if we have the line:
y = -3*x - 8
The family of perpendicular lines to this one is:
y = -(1/-3)*x + c
y = (1/3)*x + c
where c can be any real number.
Now we also want that this line passes through the point (9, -4)
Then we need to replace x by 9, and y by -4
-4 = (1/3)*9 + c
Now we can solve this for c.
-4 = 9/3 + c
-4 = 3 + c
-4 - 3 = c
-7 = c
Then the line that is perpendicular to the line y = -3x – 8 and that goes through (9, -4) is:
y = (1/3)*x - 7
Carlos jogged 5 laps around the school track in 8 minutes. What was his average speed in laps per minute? lap(s) per minute PLEASE I NEED ANSWER I WILL GIVE BRAINYLIST
Answer:
To solve this problem, you would create two ratios and make them equal to each other, both representing laps:minute or laps/minute! With that being said, laps will be in the numerator, or on top, and minutes will be in the denominator, or the bottom! The first ratio, which we know from the problem, will be 5/8. In order to write the second ratio, we need to come up with something to put in place for what we're solving for. I like to use x. So, we need to find how many laps (x) are run in 1 minute. Remember, laps are on top and minutes are on the bottom. The second ratio would look like x/1. Then we make them equal to each other -> 5/8=x/1. You would then solve this equation by multiplying the right side of the equation by the reciprocal of the denominator! So, it would be 1/1(5/8)=x. Because then multiple the numerators and the denominators -> 1(5)=5 and 1(8)=8! This makes the equation turn into x=5/8! Because x equals the number of laps run in one minute, we can say that Ricky ran 5/8 of a lap in one minute or 0.625 laps in one minute!

30. Find the value of expression 20m2 + 30m + 40 when a)m = -3 b)m= - 4 c) m = 3
Answer:
di you mean m² when you say m2 or not?
The values of the expression are;
-21, 240, 310 respectively
We were given the equation as ;
20 [tex]m^{2}[/tex] + 30m + 40
Then we can find the values of the expression with the given options to know the answer by input the value of ' m' into the given equation
Option (a) (m=-3)20( [tex]-3^{2}[/tex] )+ 30(-3)+ 40 = -21Option (b) (m=-4)20([tex]-4^{2}[/tex] )+ 30(-4)+ 40 = 240Option (c) (m=3)20([tex]3^{2}[/tex]) + 30(3)+ 40 = 310Therefore, the values of the expression are; -21, 240, 310 respectively

If x = 9 units, y = 3 units, and h = 7 units, find the area of the rhombus shown above using decomposition. A. 21 square units B. 13 square units C. 72 square units D. 63 square units
Answer:
63 square units
Step-by-step explanation:
Area of the rhombus = Base × Height
Given
Base = x = 9unit
Height = h = 7units
Substitute into the formula
Area of the rhombus = 9×7
Area = 63units²
Hence the required area of the rhombus is 63 square units
Simplify: ( x² − 3) ( x + 2) + 6 *
Answer:
x(x + 3)(x - 1)
Step by Step :::
= (x² - 3)(x + 2) + 6
= x(x² - 3) + 2(x² - 3) + 6
= x³ - 3x + 2x² - 6 + 6
= x³ + 2x² - 3x
= x(x² + 2x - 3)
= x(x² + 3x - x - 3)
= x{x(x + 3) - 1(x + 3)}
= x(x + 3)(x - 1)

Write the equation of the line in Slope-Intercept form given the following information: The new line is PARALLEL to y = 3x - 5 The new lines goes through the point (-2, 6).
Answer:
y = 3x + 12
Step-by-step explanation:
y = 3x - 5 (y = 3x +b)
Parallel lines have same slope.
m = 3; (-2 , 6)
y - y1 = m(x -x1)
y - 6 = 3(x -[-2])
y -6 = 3(x + 2)
y - 6 = 3x + 6
y = 3x + 6 + 6
y = 3x + 12

Answer:
answer is c 3/10 and 4/10
Step-by-step explanation:
alright so 10. 5 can go into 10 2 times. the 2 times is which is what we multiply the numerator by and the 5 by both multiplying by 2 equaling 4/10 for simpler explanation
5 goes into 10 2 times
multiply both sides by 2
2 x 2 = 4

helen has to buy all the butter she needs to make 60 biscuits she buys the butter in 250 g packs what is the exact amount of butter she needs to buy
Answer:
480
Step-by-step explanation:
sorry if its wrong bro
Step-by-step explanation:
a- for 15 biscuits:
sugar=60g
for 60 biscuits, she will need:
sugar=240, as she would make 15 biscuits 4 times to get a total of 60 biscuits
the amount of flour must be 3×sugar used
so amount of flour she needs is 720g
b i- she needs a total of 480g butter as butter is 2× of sugar used
ii- since she buys in 250g packs, she would have to buy 2 packs
20 g will be left after she finishes making the biscuits
