4. Your first six-month auto insurance premium was $729.00. Based on your good
driving record, your renewal premium is $648.81. What percent decrease did you see
in your premium? (2 points)
I
Answer: 11%
Step-by-step explanation:
729-648.81=80.10
What percent is 80.10 of 729
%/100 = is/of (this may help you)
X/100 = 80.10/729 (cross multiplication)
(80.19*100)/729 =
11%
Given that measure angle AEB equals 4x+1 and measure angle CED equals 3x, determine the missing measures.
[tex]\\ \rm{:}\dashrightarrow 4x+1=3x[/tex]
[tex]\\ \rm{:}\dashrightarrow 4x-3x=1[/tex]
[tex]\\ \rm{:}\dashrightarrow x=1[/tex]
Now
[tex]\\ \rm{:}\dashrightarrow 3x=3(1)=3[/tex]
[tex]\\ \rm{:}\dashrightarrow 4x+1=4(1)+1=5[/tex]
Answer:
AEB = -3
CED = -3
Step-by-step explanation:
We can make an equation and solve for x.
4x + 1 = 3x
~Subtract 1 to both sides
4x = 3x - 1
~Subtract 3x to both sides
x = -1
Now we can substitute that value of x into both angles.
4(-1) + 1 = -4 + 1 = -3
3(-1) = -3
Best of Luck!

5) What is the result of subtracting (x2 + 3x)from the polynomial (-2x2 + 4x + 5)?
Answer:
- 3x² + x + 5
Step-by-step explanation:
- 2x² + 4x + 5 - (x² + 3x) ← distribute by - 1
= - 2x² + 4x + 5 - x² - 3x ← collect like terms
= - 3x² + x + 5
Hi
Golden rule to know by heart : you can only add or substract element of the same kind.
so X^2 with X^2 , X with X , numbers with numbers...
exemple : 2X^2 +3X^2 = 5X^2
but 5X^2 -3X remains that way as 5X^2 is a " X^2" and " 3X" is a " X" so I can't substract two elements of different kind.
Now you have to translate what is ask of you into a calculus.
so : you have
A ) ( 2x^2+4x +5) - ( x^2+3x)
Math is a sport of the mind. You will only progress and become stronger if you train.
So I let you have a shot. beware of signs rules. If you still have trouble, ask in comment section..
Pls help me :) I would appreciate it

in which case xy 5 and yz = 3
The total would be 8.
if they are situated like this
x z y
then xy = 5 and yz = 3 but its going the opposite way.

X= (2a+5)² Y= (a-3)²
X+Y??
Answer:
X = (2a + 5)^2 = 4a^2 + 20a + 25
Y = (a-3)^2 = a^2 - 6a + 9
4a^2 + 20a + 25 + a^2 - 6a + 9
X + Y = 5a^2 + 14a + 34
Which best describes a compass tool?

Find the midpoint between 3pi and pi
Explanation:
We apply the midpoint formula like so
C = (A+B)/2
C = (3pi+pi)/2
C = (4pi)/2
C = 2pi
This means 2pi is exactly halfway between pi and 3pi
This is similar to saying that 2 is halfway between 1 and 3. Think of the "pi" as "1pi", and we're effectively just looking at the coefficients.
Which ordered pair is a solution of the system of equations? y= 3x + 1 y= 5x - 1 A (2,3) © (1,2) B (0, 1) D (1,4)
Answer:
D
Step-by-step explanation:
So first, we have to test the pairs. Let start with equation 1.
7=\=3 x
4=\=2 x
0=0 ✓
4=4 ✓
Now we only have to test B and D.
0=\=-1
4=4 ✓
D is the correct answer.

Rotate ΔCAR if C(-1,-4), A(2,3), R(-3,-2) 180° about the origin
Answer:
C(1,4) , A(-2,-3), R (3,2)
Step-by-step explanation:
the formula thing for rotating 180° about the origin is (x,y) -> (-x,-y)
this doesn't mean make the number negative, but make it the opposite if that makes sense
e.g. F(2,-4) -> F(-2,4)

2(x-1)(x+2)[tex]2(x-1)(x+2)[/tex]
[tex]\boxed{\underline{\bf \: ANSWER}}[/tex]
I assume the following equation is the question you asked.
[tex] \rightarrow \sf \: 2(x - 1)(x + 2)[/tex]
If yes, these are the following are the steps to reach your answer :-
[tex]\sf \: 2(x - 1)(x + 2)[/tex]
Use the distributive property to multiply 2 by x - 1.
[tex] \sf \: \left(2x-2\right)\left(x+2\right) [/tex]
Apply the distributive property by multiplying each term of 2x - 2 by each term of x + 2.
[tex] \sf \: 2x^{2}+4x-2x-4 [/tex]
Combine 4x and - 2x to get 2x.
[tex] \boxed{ \bf \: 2x^{2}+2x-4 }[/tex]
=> The answer will be 2x² + 2x - 4.
