5x-8y=40 what is the x intercept

1 answer:

8 0

Hello! The x-intercept is where the line crosses the x-axis when y = 0. We already have the expression shown. We will plug in 0 as y to get this:

5x - 8(0) = 40.

As you probably know, anything times 0 is 0, so -8 * 0 is 0. All we have is 5x = 40. Divide each side by 5 to isolate the x. 5x/5 cancels out. 40/5 is 8. There. x = 8. The x-intercept is (8, 0).

Brainliest? :(

Svetlanka [38]

Answer:

$(f\cdot g)(x)=2x^2+10x+12$

$(f-g)(x)=-x-1$

$(f+g)(1)=10$

Step-by-step explanation:

$\tt f(x)=x+3$

$\tt g(x)=2x+4$

$(f\cdot g)(x)=f(x)\cdot g(x)=(x+3)(2x+4)=2x^2+4x+6x+12$

$=2x^2+10x+12$

$(f-g)(x)=f(x)-g(x)=x+3-(2x+4)=x+3-2x-4$

$=-x-1$

$(f+g)(1)=f(1)+g(1)=1+3+2(1)+4$

$=4+2+4=10$

Determine the solution to the following system of equations: 2x+4y=-12 x+2y=-2

jolli1 [7]

Answer:

undefined/no solution

Step-by-step explanation:

you use elimination to solve. So multiply 2x+4y=-12 by 1 and x+2y=-2 by 2. then you subtract 2x+4y=-12 by 2x+4y=-4 and get 0y=-8. Anything divided by 0 is undefined/no solution because you can't divide anything by 0.

For which interval is the function increasing<br><br> Choose two answers that are correct

kaheart [24]

Answer:

-8 ≤ x ≤ - 6

2 ≤ x ≤ 6

Step-by-step explanation:

Increasing part of the function can be easily determined from the graph.

Note that increasing function means for each successive values of 'x', the values of 'y' keep increasing.

From the graph, we see that the function is increasing in the interval $- 8 \leq \ x \leq -6$

Between -6 and -4, the graph is constant and takes the value 4.

After that it decreases till x = -2 until it becomes a constant function again on x = 2.

Then, it again increases from x = 2 till x = 6. This is represented by the interval

$2 \leq x \leq 6$ .

Then it again decreases.

So, OPTION A and C are the answers.
