Answer: −y^2+18y
Let's simplify step-by-step.
5y(4−(y+2))+4y(y+2)
Distribute:
=(5y)(4)+(5y)(−y)+(5y)(−2)+(4y)(y)+(4y)(2)
=20y+−5y2+−10y+4y2+8y
Combine Like Terms:
=20y+−5y2+−10y+4y2+8y
=(−5y2+4y2)+(20y+−10y+8y)
=−y^2+18y
Answer:
= −y^2+18y

Two hikers walk on a trail in the direction of increasing mile marker numbers. Mandy starts at mile marker 1 and hikes at a rate of 2.5 miles per hour. At the same time, Rita starts at mile marker 2 and hikes at a rate of 3 miles per hour. The equation 2.5h+1=3h+2 represents the number of hours h it will take Mandy to catch up with Rita.
Let as consider, we need to find the number of hours h it will take Mandy to catch up with Rita.
Given:
The number of hours h it will take Mandy to catch up with Rita is represented by the equation
[tex]2.5h+1=3h+2[/tex]
To find:
The value of h.
Solution:
We have,
[tex]2.5h+1=3h+2[/tex]
Isolate the variable terms on one side.
[tex]2.5h-3h=-1+2[/tex]
[tex]-0.5h=1[/tex]
Divide both sides by -0.5.
[tex]h=\dfrac{1}{-0.5}[/tex]
[tex]h=-2[/tex]
We know that, time cannot be negative. So, [tex]h\neq -2[/tex].
The equation [tex]2.5h+1=3h+2[/tex] is not true for any positive value of h.
Therefore, Mandy will never catch up with Rita.

An angle is 36⁰ less than its complement. What is the measure of the angle?
Answer:
27 degrees.
Step-by-step explanation:
If the angles are x and y then as they are complementary:
x + y = 90 - and we are given that:
x - y = 36 Adding the 2 equations:
2x = 126
x = 63.
So 63 - y = 36
y = 63 - 36 = 27.

Find 2 points that are 3 units from Point C and also share the same y-coordinate as Point C.
P.S its NOT -3,-5 -9,-5
Answer:
I'm guessing point C is (-6,-5)? But then, it would have to be the coordinates you listed, (-3,-5) and (-9,-5) because nothing else makes sense.
Or is it one of those questions that you give your own coordinates? I'm confused :'(

If two lines are parallel and the slope of one of the lines is M, what is the product of their slopes? *
2 points
1
2M
M²
-1
Thanks will mark brainliest
Answer:
M²
Step-by-step explanation:
Parallel lines have equal slopes.
One line has a slope of M then the line parallel to it has a slope of M , thus
product of slopes = M × M = M²
The the product of their slopes is M².
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:
two lines are parallel
and the slope of one of the lines is M
Also, the parallel lines have the same slope.
So, both the line lines have slope M.
Now, the the product of their slopes
= M x M
= M²
Hence, the product of their slopes is M².

Step-by-step explanation:
HOPE THIS HELPEDDDD ❤✨
Answer:
The original price of the candles was $4.69
Step-by-step explanation:
$11.96 (price of 4 candles) ÷ 4 candles = $2.99 (how much each candle costs)
$2.99 (how much each candle costs) + $1.70 (how much the price of the candles lowered) = $4.69 (the old price per candle)
