If y = -x and x + 6y = 30, what is the<br> value of x?
jekas [21]

Answer:

x = -6

Step-by-step explanation:

y = -x  equation 1

x + 6y = 30   equation 2

using equation 1 in equation 2 we have:

x + 6(-x) = 30

x - 6x =30

-5x = 30

x= -30/5

x= -6

1.Find the slope of the line through (-6, 11) and (15, 20).
GrogVix [38]

Answer:

\boxed {\boxed {\sf m= \frac{3}{7} }}

Step-by-step explanation:

We are asked to find the slope of a line. The slope tells us the steepness and direction of a line. It is found by dividing the change in y by the change in x.

m= \frac{ \Delta y }{\Delta x}

m= \frac{y_2-y_1}{x_2-x_1}

In this formula, (x₁, y₁) and (x₂, y₂) are the points the line passes through. We are given the points (-6, 11) and (15,20). If we match a value with its corresponding variable, we see that:

  • x₁ = -6
  • y₁ = 11
  • x₂ = 15
  • y₂ = 20

Substitute the values into the formula.

m= \frac{20-11}{15 - -6 }

Solve the numerator.

m= \frac{9}{15--6}

Solve the denominator. 2 back to back negative signs become a positive sign.

m= \frac{9}{15+6}

m= \frac{9}{21}

Simplify the fraction. 3 divides evenly into the numerator and denominator.

m= \frac{9/3}{21/3}

m= \frac{3}{7}

The slope of the line is <u>3/7.</u>

2x+3x^2(4x-5)<br> please helpppp asap
Aliun [14]

Here's my step-by-step explanation:

We're just gonna factor.

If your teacher has spoken of FOIL, then he/she has probably said that it means First Outer Inner Last and that it helps with distributing problems like these.

Right, so let's get to it.

2x+3x^2 (4x-5)\\2x(4x-5)+3x^2(4x-5)\\2x(4x) + 2x(-5) + 3x^2(4x) + 3x^2(-5)

Can you see the FOIL method being spread out here? Let's keep going.

2x(4x) + 2x(-5) + 3x^2(4x) + 3x^2(-5)\\8x^2 + (-10x) + 12x^3 + (-15x^2)\\12x^3 + 8x^2 - 15x^2 -10x\\12x^3 -7x^2 -10x

Hope this helps, and let me know if I made a mistake! ^_^

Subtract 7x+27x+2 from -5x^2-2x−5x 2 −2x.
kicyunya [14]

Simplified value of  subtraction of 7x+27x+2 from -5x^2-2x−5x 2 −2x. is -10x^{2} -38x-2.

Given Expressions  7x+27x+2 and  -5x^2-2x−5x 2 −2x.

Expressions refers to the combination of numbers, variables and symbols. It represents the relationship between variables. They are solved for finding out the value of variables. It is mainly not in equal to form. Subtraction is possible when subtracting the coefficients of same variable.

We have to subtract 7x+27x+2 from -5x^2-2x−5x 2 −2x. and to do this we need to first solve the expressions itself.

7x+27x+2=34x+2------------------1

-5x^{2} -2x-5x^{2} -2x=-10x^{2} -7x-2x--------------------2

Now subtract 1 from 2

=-10x^{2} -7x-2x-34x+2

=-10x^{2} -38x-2.

Hence the simplified value of subtraction is -10x^{2} -38x-2.
