0,4 Find the roots of the following quadratic equations
using the quadratic formula
1) 6a²x² - 7abx - 3b²=0, a is not equal to zero
pls answer
Answer:
b = b2-4ac
= (-7ab)^2 -4 (6a^2)(-3b^2)
= 49a^2b^2 + 72a^2b^2
= 121a^2b^2
Now, x = (7ab +- root 121a^2b^2)÷2(6a²)
= (7ab +- 11ab ) ÷ 12a²
= ( 20ab)/12a² or 4ab/12a²
= 5/3ab or - 1/3ab .
So, these are its roots .

why are 1/4 and 3/8 represented with negative numbers on the number line in the example
Answer: There's no image there, but I assume it's because they are behind the 0.
Step-by-step explanation: The range of real numbers goes from - infinity to positive infinity. The 1/4 and 3/8 that are on the number line are probably behind the 0, indicating that they are negative numbers. I don't know if what I'm saying makes sense in the context of the problem (since you didn't provide a picture).

Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The first step you should take is to distribute the 2, so if you do that it'll leave you with... [tex]12=-4v+2v+4[/tex]
Then you notice the like terms and then you have to combine them and that'll give you... [tex]12=-2v+4[/tex]
Now you subtract the 4 to both sides and get... [tex]8=-2v[/tex]
Lastly the fun step is to divide the -2 to both sides and to get the answer of...
[tex]v=-4[/tex]

Over the course of 4 months, Spiffy the dog lost 36 pounds. What integer represents his loss per month?
Answer:
-9 pounds / month
Step-by-step explanation:
A loss of 36 pounds is a negative number
-36
Divide by the number of months
-36 pounds / 4 months
-9 pounds / month
Divide total loss by number of months:
36 pounds / 4 months = 9 pounds per month.
Because it lost weight the integer would be negative 9 (-9)

Julio says, "If you subtract 17 from my number and multiply the difference by -5, the result is
- 70." What is Julio's number?
Answer:
Julio's number is 31.
Step-by-step explanation:
Okay, so -70 divided by -5 is 14.
14 plus 17 equals 31.
If you subtract 17 from 31, you get 14.
Then, if you multiply 14 times -5, you get -70.

Answer:
X=19
Step-by-step explanation:
A full line must be 180 degrees and you already know that part of the line is 66 degrees. You do 180 minus 66 which gives you 114. That is the other unknown angle but it is asking for x, not the angle. You do 114 divided by 6 to get 19. Therefore, x=19.

________
X2-x1
-7 - (-8) = 1
6-4=2
Slope is 1/2
The slope of the line through (6, -7) and (4, -8)
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
where (x₁, y₁) and (x₂, y₂) are the two points that you are trying to find the slope between.
Given;
Two points; (6, -7) and (4, -8)
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
m=(-8-(-7))/(4-6)
m=(-1)/-2
m=1/2
Therefore, the slope between the two given points will be1/2

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that sporting goods store is offering a 20% discount on shoes. Mariana also has a $5 off coupon that can be applied to her
purchase.
She is planning to buy a pair of shoes that originally costs = $89.
The discount price is the same either way.
Thus 20 percent of $89.00= 17.80$
Therefore, we have;
$89.00 - ($5.00 x $17.80) = $66.20
$89.00 - ($17.80 x $5.00) = $66.20

Find the slope of a line through the given points.
(3-7), (5,5)
Answer:
11/2
Step-by-step explanation:
Answer: m = 6
Step-by-step explanation: Start by writing down the slope formula.
m = y₂ - y₁ / x₂ - x₁
We take the second y minus the first y over the second x minus the first x.
m = 5 - (-7) / 5 - 3
m = 12 / 2
m = 6
So the slope of our line is 6.
