Explain how to find the x-intercept of the graph of y = 4x - 2.

There are two ways to do this. The first of which is the algebraic method. Plug in y = 0 and solve for x.

y = 4x - 2

0 = 4x - 2 ... y is replaced with 0

4x-2 = 0

4x-2+2 = 0+2 ... we add 2 to both sides

4x = 2

4x/4 = 2/4 .... divide both sides by 4

x = 1/2

x = 0.5

The x intercept is x = 1/2 or x = 0.5

--------------------------

The other approach is to graph the equation y = 4x-2, and mark where the line crosses through the x axis. You should find it crosses through x = 1/2 or x = 0.5; the x intercept as an ordered pair would be (1/2, 0) or (0.5, 0)

side note: the equation y = 4x-2 goes through the points (0,-2) and (1,2). You find this by plugging in x = 0 and x = 1 respectively to find the corresponding y values.

Which of the following is a true statement about the equation y= -7/8x+10
-BARSIC- [3]
First of all we can rule out that the slope is 10. The coefficient before the x term is not 10 so the answer is not a.

Following on what I said for option a, option b is correct as the coefficient before the x term is -7/8. Therefore the answer is B.

The answer is not C as when x = 0, y is not 0. This means the line does not pass through the origin (0,0)

Option D is not true aswell. When x = 1, y= 9.125. When x= 2, y= 8.25. When x=3, y= 7.375. X is increasing whereas y is decreasing. Therefore option D is ruled out.

The answer is option B.

I hope this has helped you.

Find the area of the shape shown below.<br> 3.5,2,2,2,2,5
natta225 [31]

Answer:

26.75

Step-by-step explanation:

It is 26.75 because if you split the traingle in half from the bottom to the top you look to find the area of each shape, so the sqaure has a measure of 2 by 2 so that is four then the smaller triangle has a measure of 2 by 2 but the formula for triangles are length times height divided by 2 and the area for that is 2. Then the other smaller triangle is 5 * 2 which is 10 then divide it by 2 so it is 5 so all together it is 9. then the area of the biggest triangle is 15.75

Ow is the product of 3 and –2 shown using integer tiles?
PIT_PIT [208]

The correct answer is option C which is 3 sets of 2 negative tiles.

<h3>What is multiplication?</h3>

Multiplication is the process of determining the product of two or more numbers in mathematics.

We have the product of 3 and -2. We can represent this as 3 is equivalent to -2 negative tiles.

When we add -2 three times -2 - 2 -2 = -6 we will get -6 that is 3 sets of 2 negative tiles.

So when we multiply it by 3, we end with 3 sets of 2 negative tiles. This is because the order of the factors does not change the product.

Therefore the correct answer is option C which is 3 sets of 2 negative tiles.
