The solution of the given equation 3x²+ 5x +2= 0 is given by :
option c. x = -2 / 3 or x = -1.
As given in the question,
Given equation is equal to :
3x²+ 5x +2= 0
Solve the given equation by splitting the middle term of the quadratic equation we have,
3x²+ 5x +2= 0
⇒ 3x²+ 3x + 2x + 2 = 0
⇒ 3x ( x + 1 ) + 2 ( x + 1 ) = 0
⇒ ( 3x + 2 ) ( x + 1 ) = 0
⇒ ( 3x + 2 ) = 0 or ( x + 1 ) = 0
⇒ x = -2 / 3 or x = -1
From the given options :
option c. x = -2 / 3 or x = -1 is the solution.
Therefore, the solution of the given equation 3x²+ 5x +2= 0 is equal to :
option c. x = -2 / 3 or x = -1 .
The above question is incomplete, the complete question is:
Which of the following is a solution of the equation 3x²+ 5x +2= 0?
a. x = 2/3 or x = 1
b. x = -2/3 or x = 1

how to factorise
25x²- 64y²
Answer:
(5x + 8y)(5x - 8y)
Step-by-step explanation:
Since both terms are perfect squares, factor using the difference of squares formula, a^2 - b^2 = (a + b)(a - b) where a = 5x and b = 8y.

27 of the 180 vehicles in a movie theater parking lot are minivans.What percent of the vehicles in the parking lot are minivans?
Answer:
160
Step-by-step explanation:
Answer:
15 percent
Step-by-step explanation:
First use the equation part over total to get 27/180. Then reduce the equation by dividing both the numerator 27 and the denominator 180 by 9. You are left with 3/20. Then use your calculator or you can work it out long hand to get 0.15. You times 0.15 by 100 if you want to find the percent, leaving you with 15 percent.

a. x = 12, y = 84, z = 20
b. x = 6, y = 174, z = 20
c. X= 6, y = 84, z = 10
d. x = 12, y = 174, z = 10
For the M1 angle, we can conclude the size of angle is 90°. Do the angle equation like this :
15x=90
x = 90/15
x = 6
Do the same thing in M2 :
Subtitute the x value to equation, then evaluate the value by using 90 because it's the same.
x+y=90
6+y=90
y=90-6
y=84
M3 value is same, 90°
9z=90
9z/9 = 90/9
z=10

Estelle's graduation picnic will cost $15 if it has 5 attendees. If there are 26 attendees, how much will Estelle's graduation picnic cost? Solve using unit rates.
Answer:
You can try to do a direct rule of three in this exercise.
We can considerr that the relation is proportional and we know that in this case it's dorect, as the more attendees there come, the more Estelle will have to pay, so we can write this and get x:
5 attendees - 15 dollars
26 attendees - x dollars
x = 26*15 / 5 = 78 dollars
So you know how much Estelle would have to pay

What is 30% of 42
I’ve given up on my homework please help
30% of 42 is 12.6.
sorry if wrong.
hope it helps.
have a great day.
Answer:
30% of 42 is 12.6.
Step-by-step explanation:
Ok, so first you need to find the value of 1%. To do that, you divide 42 by 100. That gives you 0.42. So, 0.42 = 1%. TO find 30%, multiply the value of 1% by 30. That's 0.42 * 30, which gives you 12.6. Therefore, 30% of 42 is 12.6!

The graph of a linear function is often a parabola.
True or False
A linear function has a graph as a straight line so the given statement is False.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
A linear function is given by
y = mx + c where m is the slope and constant.
Since it is constant it means it should be a straight line in coordinate geometry.
Therefore a linear function always makes a straight line, not a parabola.
Hence "A linear function has a graph as a straight line so the given statement is False".

Translate X(2,3) Y(0,0) Z(4,4) 2 units right and 3 units up
Answer:
X(4, 6) Y(2, 3) Z(6, 7)
Step-by-step explanation:
If you want to translate something right on a number line, then you are essentially adding to it. Thus you would just add 2 to each of the x values of the coordinates. The same applies with translating something up, all that really means is that you are adding to each of the y values so all you have to do is add 3 to each of the y values and you get your answer.
Answer:
X:(4,6), Y:(2,3), Z:(6,7)
Step-by-step explanation:
2 units right implies a change on the x-axis, meaning you add 2 units to the x of the coordinate pair (x, y). 3 units up implies a change in Y, you apply the same rule and add 3 to the Y of the pair.
2 units right (add 2 to x pair coordinate)
X: (2,3) --> (4,3)
Y: (0,0) --> (2,0)
Z:(4,4) --> (6,4)
and 3 units up (add 3 to y pair coordinate)
X: (4,3) --> (4,6)
Y: (2,0) --> (2,3)
Z: (6,4) --> (6,7)

A movie theater is located at (1,7) after walking 6 blocks to the movie theater you meet you friend at your friend's house. What ordered pair corresponds to the location of your friend's house
Answer:
(-5,1)
Step-by-step explanation:
Given the coordinate of the location of the theatre as (1,7)
If this was the coordinate after moving 6 blocks to your friend's house, then the coordinate of the location of my friend house will be gotten as thus;
C = (1-6, 7-6) (since he moved 6blocks)
C = (-5, 1)
