Fine two integers that have a sum of -17 and a product of 52. What are the integers?
Answer:
{4, 13}
Step-by-step explanation:
Represent the integers by I and J. Then I + J = -17 and I*J = 52.
Let's solve this system using substitution. Solve the first equation for I as follows:
I + J = -17 becomes I = -J - 17
Substitute -J -17 for I in the second equation:
(-J - 17)*J = 52
Performing the indicated multiplication, we get:
-J^2 - 17J - 52 = 0
Let's solve this using the quadratic formula. The quadratic coefficients here are {-1, -17, -52}, and so the discriminant, b^2 - 4ac, is
(-17)^2 - 4(-1)(-52), or 289 - 208, or 81. This result is positive, so we know that the quadratic equation has two real, unequal roots. They are:
17 ± √81 17 ± 9
J = --------------- = ---------------
2(-1) -2
Evaluating this last result, we get J = (17 + 9)/2, or J = 13, and
J = (17 - 9)/2 = 8/2, or J = 4

Use the table to write the slope-intercept equation of the line below.
Answer:
y=1/2x+5
Step-by-step explanation:
m= change in y over change in x; the y-value is going up by 1 every time; the x-value is going up by 2; change in x/change in y is 1/2
b= whatever value the y is when x is 0 is your y-intercept; when x is 0 y is 5

The function g is defined by g(x) = -3x + 2. Which statements are true? Select ALL that apply.
f{-2) is greater than g(-2).
f{-1) is less than g(-1).
f{0) is greater than g(0)
f(1) is less than g(1).
f(2) is greater than g(2).
Answer:
f{0) is greater than g(0) and f(2) is greater than g(2).
Step-by-step explanation:
f{0) is greater than g(0) = f(0)=8 and g(0)=2
f(2) is greater than g(2) = f(2)=8 and g(2)= -4
The two statements that are correct are f(0) is greater than g(0), and f(2) is greater than g(2).
What is the general equation of parabola?The general equation of a parabola is given as,
[tex]y=a(x-h)^2+k[/tex]
where (h,k) is the coordinate of the vertex of the parabola.
The equation of the parabola with vertex (1,9) can be written as,
[tex]y=a(x-h)^2+k\\\\y=a(x-1)^2+9[/tex]
Now, the value of a can be found by putting one zero of the parabola,
[tex]y=a(4-1)^2+9\\\\0=a(3)^2+9\\\\-9=a(3)^2\\\\-9=a9\\\\a=-1[/tex]
Thus, the equation of the parabola can be written as y=-(x-1)²+9.
A.) The value of the two functions when the value of x is -2 can be written as,
[tex]f(x)=-(x-1)^2+9\\\\f(-2)=-(-2-1)^2+9\\\\f(-2)=0[/tex]
[tex]g(x) = -3x + 2\\\\g(-2) = -3(-2) + 2\\\\g(-2)=8[/tex]
Therefore, f(-2) is less than g(-2).
B.) The value of the two functions when the value of x is -1 can be written as,
[tex]f(x)=-(x-1)^2+9\\\\f(-1)=-(-1-1)^2+9\\\\f(-2)=5[/tex]
[tex]g(x) = -3x + 2\\\\g(-1) = -3(-1) + 2\\\\g(-1)=5[/tex]
Therefore, f(-1) is equal to g(-1).
C.) The value of the two functions when the value of x is 0 can be written as,
[tex]f(x)=-(x-1)^2+9\\\\f(0)=-(0-1)^2+9\\\\f(0)=8[/tex]
[tex]g(x) = -3x + 2\\\\g(0) = -3(0) + 2\\\\g(0)=2[/tex]
Therefore, f(0) is greater than g(0).
D.) The value of the two functions when the value of x is 1 can be written as,
[tex]f(x)=-(x-1)^2+9\\\\f(1)=-(1-1)^2+9\\\\f(1)=9[/tex]
[tex]g(x) = -3x + 2\\\\g(1) = -3(1) + 2\\\\g(1)=1[/tex]
Therefore, f(1) is greater than g(1).
E.) The value of the two functions when the value of x is 2 can be written as,
[tex]f(x)=-(x-1)^2+9\\\\f(2)=-(2-1)^2+9\\\\f(2)=8[/tex]
[tex]g(x) = -3x + 2\\\\g(2) = -3(2) + 2\\\\g(2)=-4[/tex]
Therefore, f(2) is greater than g(2).
Thus, the two statements that are correct are f(0) is greater than g(0), and f(2) is greater than g(2).

Tara's meal cost $8.60. She had to pay sales tax of 7%. Then she left a 10% tip based off the new total. What did she spend altogether?
Answer:
She spent $10.12
Step-by-step explanation:
8.60*.07 = .602, round that to .60
8.60 + .60 = 9.2
9.2*.10 = .92
9.2 + .92 = 10.12
Answer:
$10.12
Step-by-step explanation:
Do $8.60 + $8.60(7%) = $9.20
Then $9.20 + $9.20(10%) = $10.12

When a number is decreased by 54%, the result is 28. What is the original number to the nearest tenth?
Answer:
x=60.9
Step-by-step explanation:
Let x represent the number
x - 54%x = 28
x - 0.54x = 28
0.46x = 28
Divide both sides by 0.46
x = 28/0.46
x = 60.86
x = 60.9

explain the difference between independent and dependent events AND how I can tell the difference in a word problem.
Example: Suppose you have a bag of marbles, there are 4 white, 4 zebra striped, and 2 black. You take out a marble without looking, you do not replace it and then you take out another marble. What is the p
Answer:
The difference between the two is that in a dependent event an action will affect the ultimate outcome, but in an independent event an action won't affect the ultimate outcome. A way to tell is if the total number of the "item" at hand will be affected by the action the question is saying. In the case of the example given, that is a dependent event because the total of marbles you started with is changed due to you not replacing the one you first took. Therefore the probability is now different.

Step-by-step explanation:
IF you count the dots for each graph, you would see that the minimum for B is Higher than group A's maximum, Therefore, the numbers do not overlap. This means that at a simple glance you can see which company does better.
The perimeter of a rectangle is 86. The length of the rectangle is one more than twice the width. Determine the length and width of the rectangle.
There are two equation of the system
(1) The perimeter
2(w + l) = p
2(w + l) = 86
(2) The length and the width
2w = l + 2
From the second equation
2w = l + 2
l + 2 = 2w
l = 2w - 2
Subtitute l with 2w - 2 in the first equation to find the width
2(w + l) = 86
2(w + 2w - 2) = 86
2(3w - 2) = 86
6w - 4 = 86
6w = 90
w = 15
Now, find the length by subtituting w with 15
l = 2w - 2
l = 2(15) - 2
l = 30 - 2
l = 28
The dimension of the rectangle
length = 28 cm
width = 15 cm

Which of the following expressions represent 15% tip on a $20 meal? Which represents the total bill? **Select all that apply**. Explain your reasoning for the choices you select.
A.) 1520
B.) 20+0.1520
C.) 1.1520
D.) 1510020
Answer:
15/100 * 20, because the meal is 20 dollars and to find the percent of something you divide it with 100 so you will divide 15 with 100 and you’ll get 0.15. Then you will times it with the amount the meal cost because thats the charge. So 0.15•20 and you’ll get $3. A 15% tip for a $20 meal is $3.
