Answer:
(3 +/- i*sqrt(151) / 20 (no real solutions)
Step-by-step explanation:
10x^2 - 6x + 4 = -3x
Add 3x to both sides
10x^2 - 6x + 4 + 3x = -3x + 3x
10x^2 - 6x + 4 + 3x = 0
Add like terms
10x^2 - 3x + 4 = 0
We have to use quadratic formula to find the answers
For this equation, a = 10, b = -3 and c = 4
Note: +/- is plus or minus
Quadratic formula:
x = (-b +/- sqrt(b^2 - 4ac)) / 2a
x = (-(-3) +/- sqrt(-3^2 - 4(10)(4))) / 2(10)
x = (3 +/- sqrt(9 - 160)) / 20
x = (3 +/- sqrt(-151) / 20
x = (3 +/- i*sqrt(151) / 20
if there's a "-" sign inside a square root, it will give you an imaginary number.
Example:
-sqrt(9) = -3
sqrt(-9) = 3i (first you will ignore the "- " sign, then square the number. After finding the square root, take that '-' sign and turn it to an "i")
So for sqrt(-151), 151 is not a perfect square, so you will get a decimal number. Leave it as it is:
sqrt(151). We can't forget about the "-". Turn the minus into a sign.
It will be i*sqrt(151)
Imaginary numbers can't be simplified, so this is the answer.
(3 +/- i*sqrt(151) / 20

g(0)=-x-2
Answer:
g(0) = -2
Step-by-step explanation:
g(x) = -x - 2
To find g(0), replace x with 0 in the equation.
g(0) = -0 - 2 = -2

7/8 x 3/5 simplified
Answer:
21/40
Step-by-step explanation:
First you multiply the numerators (7 & 3) to get 21, then denominators (8 & 5) to get 40, unfortunately it cannot be reduced
In the scenario that it could be reduced, I was taught to cross reduce. lets say we had 2/8 x 4/6
You could divide by four for the 8 (denominator) and 4 (numerator) getting you 2/4 and 1/6
Then you do the same thing for 2 (numerator) and (6 denominator) so 2/2 is 1 and 6/2 is 3
Leaving you with 1/4 x 1/3 making it easier to multiply, and you don't have to reduce! Hope this helps!!

Which expression is equivalent to
Answer:
[tex]\frac{3}{2} x[/tex] - 2
Step-by-step explanation:
1/2 (2+ 3x -6)
1/2(3x-4)
3/2x - 2
You do the parentheses first because of PEDMAS. So 1 combined the 2 and the -6.
Answer:
The first answer (3/2x - 5)
Step-by-step explanation:
You need to multiply 1/2 by 2 which gives you 1. then when you multiply 1/2 by 3, you can't make it a whole number, so you make it a fraction and it then becomes 3/2x. Lastly, you do 1/2 times -6 which gives you -3. The equation goes from 1/2(2+3x-6) to then 1+3/2x-3. Since 1 and 3 can be subtracted because they're both whole numbers, you do 1-6 which gives you -5. The answer then becomes 3/2x -5
Hope this helped

The first equation in a system is 5x+2y=-4. Which equation gives a system with no solution.
Answer:
= 0.8 + -0.4y
Step-by-step explanation:
Simplifying
5x + 2y = 4
Solving
5x + 2y = 4
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
5x + 2y + -2y = 4 + -2y
Combine like terms: 2y + -2y = 0
5x + 0 = 4 + -2y
5x = 4 + -2y
Divide each side by '5'.
x = 0.8 + -0.4y

What is the y=mx+b of the equation x+3y=−15
Answer:
y = -1/3x - 5
Step-by-step explanation:
First, we need to get y by itself so we subtract x from both sides, giving us: 3y = -x - 15
Secondly, we need to isolate the y, so we divided the 3 out on both sides giving us: y = -1/3x - 5 which is our answer.

Step-by-step explanation:
Suppose both factors in a multiplication problem are multiples of 10. Why might the number of zeroes in the product be different than the total number of zeroes in the factors?
Answer:
Multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.
Step-by-step explanation:
Let the first five multiples of ten be
10*1= 10
10*2= 20
10*3=30
10*4=40
10*5= 50
Suppose we chose 20 and 50.
Now multiplying 20 with 50 we get
20*50= 1000
IF we count the total number of zeros in the factors ( 20 and 50) they are 2.
But the number of zeros in the product (1000) are 3.
This is because when we multiply 2 with 5 we get 10 which adds to the existing number of zeros ( i.e 2) and we get a total of 3 zeros.
And multiplying 10 with 50 we get
10*50= 500
IF we count the total number of zeros in the factors ( 10 and 50) they are 2.
But the number of zeros in the product (500) are also 2.
This is because when we multiply 1 with 5 we get 5 which does not add to the existing number of zeros ( i.e 2) and the total number of zeros remain the same.
Similarly multiplying 20 with 30 we get
20*30= 600
IF we count the total number of zeros in the factors ( 20 and 30) they are 2.
But the number of zeros in the product (600) are also 2.
This is because when we multiply 2 with 3 we get 6 which does not have a zero and the total number of zeros remain the same as in the factors.
So we see that multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.
Find the value of x in the equation below 5= x/6
Answer:
x=30
Step-by-step explanation:
Answer:
x=30
Step-by-step explanation:
To find the value of x in an equation, our goal is always to isolate it so that it's on one side of the equal sign while everything else is on the other. We can do this by performing inverse operations to cancel values out (for example, the inverse operation of addition is subtraction and the inverse operation of division is multiplication).
5=x/6
Because x is being divided by 6, we multiply both sides by 6 to cancel it out on the side with x.
5×6=(x/6)×6
5×6=x
30=x
I hope this helps!

ASA Congruence Theorem
complete the statement of each of these rules:
a (+)×(?)=(+)
b (-)×(+)=?
c (?)×(-)=?
Answer:
a) (+) × (?) = (+)
(?) = (+)
b) (-) × (+) = ?
? = (-)
c) (?) × (-) = ?
? is undefined
Step-by-step explanation:
a) (+) × (?) = (+)
From the given equation in the question, by dividing both side of the equation by (+), we have;
((+) × (?))/(+) = (+)/(+)
(?) = (+)/(+) = (+)
Therefore, we have;
(+) × (+) = (+)
(?) = (+)
b) (-) × (+) = ?
From the given equation in the question we apply the operation rules as follows;
(-) × (-) = (+)
(-) × (+) = (-)
Therefore;
(-) × (+) = ? = (-)
? = (-)
c) (?) × (-) = ?
From the rules of multiplication, we have;
(-) × (-) = (+)
(+) × (-) = (-)
Therefore, when (?) = (-), ? = +, from which we have;
(?) ≠ ?, which is an error
Similarly, when (?) = (+), ? = -, therefore, (?) and ?, always changes sign
Therefore, the equation, (?) × (-) = ?, is undefined.
