What multiplys to 6 and adds to 6

Answers

Answer 1
Answer: There is no answer to your question.

To prove so, lets look at all of the factor pairs of six

1,6

2,3

^^These numbers when multiplied equal 6. However, neither of them have a sum of 6.

1+6=7
1+6≠6

2+3=5
2+3≠6

X squared -7x-34 =10

Answers

Answer:

x = 11 or x = -4

Step-by-step explanation:

x² - 7x - 34 = 10

Subtract 10 from both sides.

x² - 7x - 44 = 10

Factor the trinominal. We need 2 numbers whose product is -44 and whose sum is -7. They are -11 and 4.

(x - 11)(x + 4) = 0

x - 11 = 0  or  x + 4 = 9

x = 11 or x = -4

A line passes through points (-4,-9) with a slope of 5/4 write an equation in slope intercept form

Answers

The equation in slope-intercept form is y = (5)/(4)x -4

Given the following points:

  • Points on the x-axis = -4
  • Points on the y-axis = -9
  • Slope, m = (5)/(4)

To write an equation in slope-intercept form:

The standard form of an equation of line is given by the formula;

y = mx + b

Where:

  • x and y are the points.
  • m is the slope.
  • b is the intercept.

First of all, we would determine the intercept:

-9 = (5)/(4) (-4) + b\n\n-9 = -5 + b\n\nb = -9 + 5

Intercept, b = -4

The equation in slope-intercept form:

y = (5)/(4)x + (-4)\n\ny = (5)/(4)x -4

Therefore, the equation in slope-intercept form is y = (5)/(4)x -4

80/36 as a mixed number

Answers

Answer:

yes because the one on top is larger than the number on the bottom

Answer:

2 2/9

Step-by-step explanation:

20/9 = 2 2/9

36 x 2 = 72

80 - 72 = 8/36

2 8/36 = 2 2/9

Simplify (–x2 +5) – (3 – 4x2)

Answers

(-x^(2) +5)-(3-4 x^(2) )
To simplify this, use the FOIL method. First, Outer, Inner, Last.
First: Multiply the first numbers in each set of parentheses.
-x^(2) *-3=3 x^(2)
Outer: Multiply the two outermost numbers in the equation.
-x^(2) *-4 x^(2) =5 x^(4)
Inner: Multiply the two innermost numbers in the equation.
5*-3=-15
Last: Multiply the last numbers in each set of parentheses.
5*-4 x^(2) =-20 x^(2)
Then, we put them all together in an equation, from the highest exponent to the lowest, then highest prefix (number before the variable) to lowest.
5 x^(4) -20 x^(2) +3 x^(2) -15
And simplify.
5 x^(4) -17 x^(2) -15
when you subtract you have to change the signs so it would be -3+4x2
then you combine like terms to get 3x2+2 i am assuming the 2"s mean squared

i have this for my math review & i just don't seem to get it...what is (.9x+.8y)^2

Answers

Can you take the quantity [ x + y ] and square it ?

Can you take the quantity  [ x + 2y ] and square it ?

Then you should have no trouble with the square of (.9x + .8y) .

The square of any binomial (expression with 2 terms) is

(square of the first term)
+ (square of the second term)
+ 2 times (product of the terms) .
