Answer:

the answer is (-15,13)

Step-by-step explanation:

try to solve for x on one equation, like 8x+9y=-3

x=-9/3y-3/8

plug x in for the next equation

6((-9/8y)-3/8)+7y=1

(-27y/4)-9/4+7y=1

y/4-9/4=1

y/4=13/4

y=13

now plug in the y value for any equation

6x+7(13)=1

6x+91=1

6x=-90

x=-15

So the answer to the system of equations is (-15,13)

what numbers would I cross multiply in this scenario (In a contain of juice, 25% is real fruit juice. The juice container is 32

Ray Of Light [21]

We do not need to cross multiply any numbers in this problem. 25% is equal to 1/4. Therefore, we can multiply the total amount of juice by the proportion of real fruit juice. This can be represented by the expression 1/4 x 32. After multiplying out, we can get an answer of 8 oz of real fruit juice.

Hope this helps!

What is the factored form of 6x2 13x 6? (x 4)(x 9) (2x 3)(3x 2) (2x 6)(3x 1) (6x 1)(6x 1).

snow_tiger [21]

Polynomial are expressions. The factored form of the polynomial 6x²+13x+6 is (3x+2)(2x+3).

<h3>What are polynomial?</h3>

Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.

In order to find the factored form of the given quadratic equation, we will break constant b(13) into two parts such that the sum of the parts is 13, while their product is equal to the product of the constant a(6) and c(6).

Therefore, the solution of the polynomial is,

$6x^2+13x+6\\\\= 6x^2 + 9x + 4x + 6\\\\= 3x(2x+3)+2(2x+3)\\\\=(3x+2)(2x+3)\\$

Hence, the factored form of the polynomial 6x²+13x+6 is (3x+2)(2x+3).
