Answer:
c = -4/3, -2
Step-by-step explanation:
3c^2+4c+8=-6c
3c^2+6c+4c+8=0
3c(c+2) + 4(c+2)=0
(3c+4)(c+2)=0
3c+4=0
c=-4/3c+2=0
c=-2Manuel bought 9 pounds of apples.
He has eaten 3
4 of a pound so far and has
$15 worth of apples left. Write and solve an
equation to find the cost of the apples per
pound to the nearest dollar. How much did
the apples cost per pound?
Answer:
1) Since Manuel bought 9 pounds and ate 3/4 of 1 pound, he has 8.25 pounds left (9 - 0.75 = 8.25)
2) Let's call "x" the cost of 1 pound of apples
3) (8.25)*(x) = $15
4) x = $1.81818 rounded to the nearest dollar is $2 / pound
Please help me, I am lost from 3.2 going down

Find the distance between these two points, (-4,0) and (4,0).
Answer:
The distance between the two points is 8 units.
Step-by-step explanation:
Hope this helps!! Have an Amazing day!!
Answer:
There's y and x which one you're are talking about?
it is x the distance is 8.
negative four + positive four will give us zero but if you add the both it will give us the distance between them
Is 0.3 the multiplicative inverse of 3 1/3? Why or why not?
Chapter : Rational Numbers
Answer:
3 1/3 = 10/3
0.3 = 3/10
a * 1/a =1
then 1/a is multiplicative inverse of a
0.3* 3 1/3 = 3/10 * 10/3 =1
0.3 is multiplicative inverse of 3 1/3
Step-by-step explanation:
Answer:
3 1/3 = 10/3
10.3 = 0.3 = 3 1/3
x * 1/x = 1
∴ yes, the multiplicative reverse of 3 1/3 is 0.3

Javon has a credit card with a $1,583 balance. His interest
rate is 8.8%. If he does not pay for 3 years, how much
Interest does he owe?
pleaseeeeee show the work
Answer:
I got x=10
Step-by-step explanation:
Step 1
Everything must add up to 180
180= 6x - 6 + 7x + 1 +55
Step 2
Combine everything
6x + 7x = 13x
-6 + 1 +55 =50
180 = 13x + 50
Step 4
Subtract. 180 -50
130 = 13x
Step 5
Divide 130/13
X=10
6(10) -6 = 54
7(10) + 1=71

Help! This is my math problem
Answer:
Step-by-step explanation:
The problem is that you cannot be sure that either triangle (it actually requires both of them) contain a right angle
What you have so far is SSA which is not one of the fundamental congruency triangles. In order to be certain of congruency the angle must be made up of the 2 given sides. You are certain that SAS will produce congruency. You are not so sure of r SSA. There are proofs of this on the internet. I urge you to look into it. Though not long, following it step by step takes a lot of patience. A cup of strong coffee is a good idea.

Henry can write 5 pages of his novel in 4 hours. At this rate, how many pages can Henry write in 8 hours?
Answer:
Henry can write 10 pages in 8 hours.
Step-by-step explanation:
Our unit rate (number of pages in a given number of hours) is
5 pages
--------------
4 hrs
It is not necessary to perform the indicated division. Just multiply this unit rate by '8 hours':
5 pages
-------------- * 8 hrs = 10 pages
4 hrs
Henry can write 10 pages in 8 hours.

The length of a rectangle is 5 centimeters less than 2 times the width.
a. Write a polynomial expression that represents ( 2 points )
the area of the rectangle.Simplify the expression.
Given:
The length of a rectangle is 5 centimeters less than 2 times the width.
To find:
The polynomial expression that represents the area of the rectangle, then simplify the expression.
Solution:
Let [tex]x[/tex] be the width of the rectangle.
The length of a rectangle is 5 centimeters less than 2 times the width.
2 times the width = [tex]2x[/tex]
5 centimeters less than 2 times the width = [tex]2x-5[/tex]
Length of the rectangle = [tex]2x-5[/tex]
We know that, the area of a rectangle is:
[tex]A=length \times width[/tex]
[tex]A=(2x-5)\times x[/tex]
[tex]A=2x^2-5x[/tex]
Therefore, the required polynomial expression is [tex]A=(2x-5)\times x[/tex] and its simplified form is [tex]A=2x^2-5x[/tex].

Car rental agencey a charges $50 per day plus 10 cents per mile driven agency b charges $20 per day plus 30 cents per mile driven for a one day rental it is cheaper to rent from ange a if you drive more
Answer:
D) 150 miles.
Step-by-step explanation:
The computation is shown below:
Given that
The Cost of the car rental agency of A is $50 + 0.10 per mile
The Cost of the car rental agency of B is $20 + 0.30 per mile
Here we assume the per mile be x
Now we equate these equations
SO,
$50 + 0.10x = $20 + 0.30x
$30 = 0.20x
x = 150
SO it would be more than 150 miles

Veterinary doctors marked 30 deer and released them. Later on, they counted 150 deer,
12 of which had marks. To the nearest whole number, what is the best estimate for the
deer population?
Answer:
375
Step-by-step explanation:
12/150 is 0.08, which is 8%
this mean 8 perfect of the population were marked
8 percent is 30 deers
30/0.08=375
i have to determine if DE is parallel to AC
Answer:
Triangle BDE and triangle BAC are similar triangles
Hence, two lines DE and AC are parallel to each other
Step-by-step explanation:
For proving that DE is parallel to AC, we are required to prove that triangle BDE and triangle BAC are similar triangles
The ratio of sides of both the triangle must be equal to each other
Hence
[tex]\frac{BE}{DB} = \frac{BC}{BA} \\\frac{16.1}{28} = \frac{20.7+16.1}{64}\\0.575 = 0.575[/tex]
and angle B is common.
Hence the two triangles are similar.
Therefore angle BDE and angle BAC are equal like wise angle BED and angle BCA are equal.
Thus, the two lines DE and AC are parallel to each other
