Answer:
[tex] 3 {x}^{2} + 12x + 5[/tex]
Step-by-step explanation:
[tex](x^2 + 3x) + (2x^2 + 9x + 5) \\ \\ = x^2 + 3x + 2x^2 + 9x + 5 \\ \\ = {x}^{2} + 2 {x}^{2} + 3x + 9x + 5 \\ \\ = 3 {x}^{2} + 12x + 5[/tex]

How can you describe the graph of the equation y= mx + b? Explain
Answer:
mx is the slope. b is the y-intercept
Step-by-step explanation:
the first thing you should always do is identify your slope this is key for graphing. remember your slope is b so what ever b is you locate that point in the x axis.
then whatever your slope is remember that it is rise over run so say your equation is y=3x+5 you plot the point on the y intercept which is 5. now 3x is your slope so you put it as a fraction to make it easier this is what it looks like in a fraction "3/1" so you go up 3 on the graph and over 1 because of rise/run

based on this given?
Answer:
Sheesh good luck
Step-by-step explanation:
.........
Answer:
3
Step-by-step explanation:
MN is not equal to NR, because MN is too long
It doesn't tell us R is the midpoint of MN, so for all we know MR and RN are completely different measurements.
PR and QR must be equivalent if R is the midpoint of the two.

Answer:
y = -0.5x + 3
Step-by-step explanation:
The equation of a linear model is generally represented as;
y = mx + b
where m
is slope and b is the y-intercept
We can get slope by using the slope equation
m =
(y2-y1)/(x2-x1)
(x1,y1) = (-4,5)
(x2,y2) = (4,1)
m = (1-5)/(4 + 4) = -4/8 = -0.5
The equation is thus;
y = -0.5x + b
to get b, we substitute any of the two points coordinates
1 = -0.5(4) + c
1 = -2 + c
c = 2 + 1
c = 3

Mark is making jackets. Mark took 2 hours to make a jacket. The jacket was made up of 50 kilograms of wool. How long do you think it will take Mark to use 500 kilograms of wool for the jackets?
Given:
Mark took 2 hours to make a jacket.
The jacket was made up of 50 kilograms of wool.
To find:
The time in which Mark use 500 kilograms of wool for the jackets.
Solution:
We have,
1 jacket take 2 hours.
Number of jackets in 50 kg of wool = 1
Number of jackets in 1 kg of wool = [tex]\dfrac{1}{50}[/tex]
Number of jackets in 500 kg of wool = [tex]\dfrac{1}{50}\times 500[/tex]
= [tex]10[/tex] Jackets
Time taken by 1 jacket = 2 hours
Time taken by 10 jacket = 20 hours
Therefore, it will take 20 hours to use 500 kilograms of wool for the jackets.
Answer:
20 hours
Step-by-step explanation:
1 jacket=50kg wool
1 jacket= 2hrs
500kg available/50kg per jacket= 10 jackets
10 jackets x 2hrs per jacket=20hrs
