Answer:

(x, y) = (-3, 2)

Step-by-step explanation:

Put the given value of y into the equation and solve for x.

... 7·2 +3x = 5

... 3x = -9 . . . . . . subtract 14

... x = -3 . . . . . . . divide by the x-coefficient

The solution (x, y) is (-3, 2).

Is y=10.2x a proportional relationship?​
BabaBlast [244]

Answer:

Step-by-step explanation:

Yes!

The condition needed to get a proportional answer is the y intercept must be 0. No other value can be added on. It doesn't matter that the constant of proportionality is not an integer. x and y will always differ by 10.2 as a multiplied value

Put another way, the fraction y/x will always give 10.2

Is the term (x+1) a factor of the polynomial shown below? <br> f(x)=x^3-10x^2+27x-12
Ksenya-84 [330]

We can tell if this is a factor of the polynomial shown by using the remainder theorem.

First, we need to set x + 1 equal to 0.

x + 1 = 0

Now, we solve for x.

x = -1

Now, we can plug this value into the polynomial, and if the solution is 0, it means there is a remainder of 0, which means they divide perfectly.

(-1)^3 - 10(-1)^2 + 27(-1) - 12 = -50

x + 1 is not a factor of the provided polynomial.

F(x)=x^2-8x+7 in factored form​
Karolina [17]

Answer:

(x-1)(x-7)

Step-by-step explanation:

To factor the equation, find two binomials which multiply to a quadratic. The quadratic's factors are found by finding two numbers that multiply to 7 and add to -8.

-1 and -7 multiply to 7 and add to -8.

(x-1)(x-7)
