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.

Rebecca is buying a new video game system that costs $190. The state sales tax rate is 4%. How much tax will Rebecca pay on the video game system?
Answer:
If the sales tax rate is 4%, the total amount of money that Rebecca will pay is equal to 190(1.04), or 197.60 dollars. This means, that the tax that Rebecca needs to pay is just 7.60 dollars.

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.

3. When solving the equation x/5 = -4; how would you solve for x? What would x equal?
Answer:
Question one X=-7 because -2 x -7 = 14
Question two X= -10 because -3 - -10=7
Question three X =-20 because -4 divided by-20
Step-by-step explanation:
Carrie and Diana ate lunch at a restaurant.
They ordered 1 pizza that cost $13.02.
Diana ordered chicken wings for $12.99 and a drink for $3.25.
Carrie ordered a salad for $6.25 and a drink for $3.25.
They left a $10.00 tip.
Diana paid for her food, plus half the cost of the pizza and half the tip. What was the total amount Diana paid?
A.$33.78
B.$27.75
C.$27.04
D.$20.77
Answer:
B) 27.75
Step-by-step explanation:
12.99+3.25=16.24
Half the tip is 5
5+16.24=21.24
Half the pizza is 6.51
21.24+6.51=27.75
The total amount paid by Diana will be equal to $27.75. Hence, option B is correct.
What is arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per the data given in the question,
Price of pizza = $13.02
Half price of pizza paid by Diana = 13.02/2 = $6.51
Price of chicken wings ordered by Diana = $12.99 and,
Price of drink that is also ordered by Diana = $3.25
Then, tip price is $10 which is paid half by Diana = $5
Then, the total expenditure by Diana will be,
= 6.51 + 12.99 + 3.25 + 5
= $27.75

Drag each expression to show whether it is equivalent to 4 × 5 or to 2 × 4 × 5.
Answer:
1st one: 4x5x2: in the 2nd box
2nd one: (4x2)+(4x3) : in the 1st box
3rd one: 2x(4x5): in the 2nd box
Last one: 4x(1+4): in the 1st box
Step-by-step explanation:
For the first one: 4x5x2, you can multiply any 2 numbers together example- you can multiply 4x5, 5x2, 4x2 then multiply the third digit I did 4x5=(20) x2= 40.. 5x2 =10 x4=40.. see they'll all end up to 40.
For the second one: (4x2)=8 (4x3)=12 add 8 and 12 it'll equal 20
For the third one: 2x(4x5) start by multiplying 4 and 5 which is 20, then multiply 20 by 2 =40
For the fourth one: 4x(1+4) 1+4=5, multiply 5 by 4 and get 20
The first box equals 40, the second box equals 20
And always remember to answer the problem in the parenthesis first, then continue with the rest of the problem. Hope this helps!! And I hope I didn't confuse any of you.. Let me know if you have any questions or if I made a mistake somewhere but besides all that have a great day! :)
4 × 5 equivalent to (4×2) + (4×3) and 4(1+4), 2 × 4 × 5 is equivalent to 4×5×2 and 2(4×5)
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
= 4×5×2 = 40
=(4×2) + (4×3) = 8+12 = 20
= 2(4×5) = 40
= 4(1+4) = 4(5) = 20
We have:
4 × 5 = 20 2 × 4 × 5 = 40
(4×2) + (4×3) 4×5×2
4(1+4) 2(4×5)
Thus, 4 × 5 equivalent to (4×2) + (4×3) and 4(1+4), 2 × 4 × 5 is equivalent to 4×5×2 and 2(4×5)

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
