Explain relationship between the factors of a quadratic expression, the roots of the related quadratic equation, and the x-intercepts if the graph of the related function
Step-by-step explanation:
So, let's use x2 - 3x - 28 as an example.
It's factors are (x - 7)(x + 4).
The roots are the x-values that make our expression equal 0. In order for x2 - 3x - 28 to equal 0, either of our factors need to equal 0, since 0 times anything is 0.
x2 - 3x - 28 = 0
(x - 7)(x + 4) = 0
x - 7 = 0
x = 7
(7 - 7)(7 + 4) = 0(11) = 0
x + 4 = 0
x = -4
(-4 - 7)(-4 + 4) = -11(0) = 0
That gives us two points on our graph, (7,0) and (-4,0). Where are those? On the x-axis! Thus, there are our x-intercepts.
By the way, for the future, along the x-axis, y = 0, so if you are asked for the x-intercepts (or roots), set y = 0 and solve for x.
Along the y-axis, x = 0, so if you are asked for the y-intercepts, set x = 0 and solve for y.
y = 02 - 3(0) - 28
y = -28
So, the y-intercept(s) of our same equation is y = -28, or (0,-28).
Boom.
Answer:
The x-intercepts are happen are when y = 0. If you tried to substitute y = 0 into a quadratic in the standard form you can not use traditional methods for solving for x.
Y=0 when looking for an x-intercept. Doing the factored form you are finding the x-intercepts. You always want the equation to equal 0 then factor out the equation till you get the numbers for the x-intercept.
Jeff worked 4 2/3 hours in the morning and 3 3/4 hours in the afternoon. How many total hours did he work today?
7 5/7 hours
7 5/12 hours
8 5/12 hours
8 1/2 hours
Answer:If you would like to know how many total hours did Jeff work today, you can calculate this using the following steps:
4 2/3 hours in the morning + 3 3/4 hours in the afternoon = 4 2/3 + 3 3/4 = 14/3 + 15/4 = 56/12 + 45/12 = (56 + 45) / 12 = 101/12 = 8 5/12 hours
Jeff worked 8 5/12 hours in total.

Of the 120 math tests, 47 were Bs. What percent of the math tests were Bs? Round to the nearest whole percent.
Answer:
39.17%
Step-by-step explanation:
Answer:
39%
Step-by-step explanation:
Percent is ALWAYS out of 100, and the unknown is percent so our first part of the equation will be %/100. Now our second part of equation: is/of
Of represets whole the total, and we have our key word “Of the 120 math tests”. We have our total: 120; 47 is our part so second part of equation: 47/120.
Our equation so far: %/100 = 47/120 now we need to multiply the numbers that we have diagonally: 100% x 47; 47/100 we’re multiplying so we’ll move two 0s to the right. Answer: 4700
Now, we’ll divide 4700 by 120. 4700/120. Answer: 39.1666666667. Round to nearest whole means round to nearest ones.
Thus, the answer is 39.
Hope this is helpful!

I need help please help
Answer:
D
Step-by-step explanation:
because the data goes from 18-25 therefore it would be D considering the plotted points range from those numbers
HELPPPPPPP!!!!!!!!!!!!!!!!!
Answer:
I think its D but I'm not positive
i need help with this question please
Answer:
The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.
