3x² + 12x + 11 +14x² + 8x + 5
= 3x² + 14x² + 12x + 8x + 11 + 5
= 17x² + 20x + 16
solve by elimination
{10x-4y=-6
{-3x+4y=-1
WORK MUST BE SHOWN
Answer:
x = -1
y = -1
Step-by-step explanation:
10x - 4y = -6 ---------------------(I)
-3x + 4y = -1 ---------------------(II)
Add equation (I) & (II) and y will be eliminated.
10x - 4y = - 6
-3x + 4y = -1 {Add}
7x = - 7
x = -7/7
x = -1
Plugin x =-1 in equation (I)
10*(-1) - 4y = -6
-10 - 4y = -6 {Add 10 to both sides}
-4y = -6 + 10
-4y = 4 {Divide both sides by (-4)}
y = 4/(-4)
y = -1
I needddd helpppp asappppp
Answer:
Step-by-step explanation:
Part A: Slope of parallel lines are equal.
4x - 3y - 7 = 0 ⇔ y = [tex]\frac{4}{3}[/tex] x - [tex]\frac{7}{3}[/tex]
m = [tex]\frac{4}{3}[/tex]
y - 3 = [tex]\frac{4}{3}[/tex] ( x + 2 ) ⇔ y = [tex]\frac{4}{3}[/tex] x + [tex]\frac{17}{3}[/tex] ⇔ 4x - 3y + 17 = 0
Part B: Slope of perpendicular lines are opposite reciprocal.
[tex]m_{1}[/tex] × [tex]m_{2}[/tex] = - 1
[tex]m_{1}[/tex] = [tex]\frac{4}{3}[/tex]
[tex]m_{2}[/tex] = - [tex]\frac{3}{4}[/tex]
y - 3 = - [tex]\frac{3}{4}[/tex] ( x + 2 ) ⇔ y = - [tex]\frac{3}{4}[/tex] x + [tex]\frac{3}{2}[/tex] ⇔ 3x + 4y - 6 = 0

75% of 48 show all the work
Answer:
36
Step-by-step explanation:
75%=0.75
0.75*48=3/4*48=144/4=36
Answer:
75% of 48 is 36.
Step-by-step explanation:
So, what I did here was to first find out what 25% of 48 is, because 75% is 25% multiplied by 3.
50% of 48 = 24
Since 25% is half of 50% all we have to do is divide by 2.
24 ÷ 2 = 12.
Now, we multiply by 3.
12 * 3 = 36
So, the answer is 36.
Hope this helps! :)

There were 60 people on bus. 40% were female. How many people were females and how many were males?
Answer:
There were 24 females and 36 men on the bus
Step-by-step explanation:
To find the amount of females on the bus you multiply the 60 passengers by 0.4 to mimic the 40% and you get 24. So there were 24 females and to find the men you simply subtract 24 and 60 to get 36

Using the compound interest formula, the "n" is what value when compounded annually?
Answer:
n=1
Step-by-step explanation:
N is the number of times per year
Annually would be one time per year so n =1
Answer:
If interest is compounded yearly, then n = 1; if semi-annually, then n = 2; quarterly, then n = 4; monthly, then n = 12; weekly, then n = 52; daily, then n = 365; and so forth, regardless of the number of years involved. Also, "t" must be expressed in years, because interest rates are expressed that way.

convert 10009 out of 17%
Answer:
Step-by-step explanation:
To convert 10,009 to 17%, turn 17% to decimal and multiply that by 10,009 (10,009 * 0.17), which equals 1,701.53
IF you meant to convert the fraction 10,009/17% (read as "10,009 out of 17 percent, ") then simply convert 17% to a decimal (0.17) and divide 10,009 by 0.17 (10,009/0.17) which is about 58,876.47, for full decimal, use a calculator and do 10,009/0.17
The question is kind of confusing so tell me what you meant
