How can I find the x-intercept in a graph if the equation is 2x+3y=6​
Varvara68 [4.7K]

Answer:

Step-by-step explanation:

First you would need to multiply 3y by zero since when finding x intercept, Y is always zero.

2x=6

next you would divide both sides by 2 and you get

X= 3 The ordered pair would be (3,0)

A company tests two new products to make sure they last for more than a year. Product 1 had 950 out of 1,000 test items last for
zheka24 [161]

Answer:

product one; it has a higher success rate

Step-by-step explanation:

to find out which has a higher rate of success we can find out their percentage of success

we can divide their success amounts by test amounts

950 / 1000 = 95/100 = 95%

150/200 = 75/100 = 75%

product 1 has a higher success rate

Find the slope of the points (2, 13) and (8, 1)
Pie
-2

y2-y1/x2-x1
take the y coordinate of the second pair of coordinates and subtract it by the y coordinate of the first pair, then take the x coordinate from the second pair of coordinates and subtract it from the x coordinate from the first pair. then put your answer from the y coordinate over the answer from the x coordinates. 1 - 13 / 8 - 2, then you get -12/6, which simplifies to 2.

Hope this helps :)
