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
Please help me if you can. Please also write how you got the answer thank you.
Answer:
1) r, q, s. 2). 5
Step-by-step explanation:
1) from the given (q) is smaller than (r) and (s) is less than (q) by 2.
2) you need to make all the fractions have the same numerator so you will multiply both the firs and third fraction by 3÷3 ( which is 1 and will not affect the value but will make the numerator of the fractions equal) and the fractions between them is the second fraction and it's denominator is x and there is 5 fractions between the two numbers so there are 5 possible values of x

18x – 4(9 – 5x) + 14
PLEASE SIMPLIFY AND SHOW YOUR WORK!
Answer:
2(19[tex]x[/tex]x -11)
0R
38x - 22
Step-by-step explanation:
QESTION: 18x – 4(9 – 5x) + 14
Rearrange terms that whould be -: 18x – 4(-5x + 9) + 14
Disterbot the one in brakect and the nagative four: – 4(-5x + 9)
SLOVE: – 4(-5x + 9) ^^ 4 x 5 = 20 and 4 x 9 = 36 ^^ PUT THE ALL TOGETHER.
What you have now --> 18x + 20x - 36 + 14
Now, it's time to use your PEMDAS, we have Add and Subtract so you are going to do A fisrt (Add).
-36 + 14 = -22
Now you have, 18x + 20x - 22
Combine the like terms: 18x + 20x = 38x (don't forget the - 22)
38x - 22
2 x 19 = 38
2 x 11 = 22
What do you notice? ------- They all have 2 right? YES!, So put 2 in the front with parentheses, then put 19x and -11 in the parentheses.
Here is your EQUATION!
2(19[tex]x[/tex] -11)

Two neighbors in a rural area want to know the distance between their homes in miles. Help 'em out! 1 mile = 5,280 feet. Find the distance between their houses in miles. (i have 69 points left so PLEASE PLEASE dont be rude and answer like this ¨ssieoiej¨)
Answer:
4/5 OR 0.8
Step-by-step explanation:
Divide the distance between them by 5,280. You should then get a decimal of 0.8. Not sure if you are looking for decimal or fraction, but 0.8 as a fraction is 4/5. So 4/5 of a mile is in between their two houses. Hope this helps :)

solve 4 + x > 6 graph the solution
Answer:
B.
Step-by-step explanation:
We know that (4 + x) is bigger than 6, so we have to find the answer that has more than 4. Since A and B both have answers that are more than 4, those are our options. But notice that A has one error, first lets define a closed circle and an open circle. A closed circle can mean it is greater than or equal to, it can also mean that it is less than or equal to. But an open circle means that it is either less than, or greater than. And because the equation has an open circle ( which is this sign >) it means that the answer is option B.
Here is a better picture of what a close circle and open circle look like:
Can you please for the love of god help me it's 2am and I cannot figure this out
Answer:
8:05 pm (If you round to the nearest tenth place)
Step-by-step explanation:
basically, 4:00 pm and 5:10 pm have a 1 hour and 10 minute difference.
1 hour and 10 minutes divided by 65 miles is 1.6923076 or 1.7 minutes
1.7 minutes times 150 miles is 2 hours and 55 minuets
2 hours and 55 minutes plus 5:10pm is 8:05 pm
I'm so sorry if I'm wrong!
Answer: a) d(t) = [tex]\frac{13}{14}[/tex] (t - 70) + 65 b: 6:41 pm
duration of time passed:
5:10 pm - 4:00 pm = 70 mins
distance = 65 miles
you points to use to make an equation:
(0,0) and (70,65) ---------------------> ( (0,0) is bc youre beginning the trip and you have no distance )
find the slope of your "future" equation
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{65}{70}[/tex] = [tex]\frac{13}{14}[/tex] = m
now use point-slope form
y - 65 = [tex]\frac{13}{14}[/tex] (x - 70)
y= [tex]\frac{13}{14}[/tex] (x - 70) + 65
and since it wants it in terms of d and t,
d(t) = [tex]\frac{13}{14}[/tex] (t - 70) + 65
part b:
150 = [tex]\frac{13}{14}[/tex] (t - 70) + 65
85 = [tex]\frac{13}{14}[/tex] (t - 70)
85 = [tex]\frac{13}{14}[/tex] t - 65
150 = [tex]\frac{13}{14}[/tex] t
2100 = 13t
161.54 = t
about 162 minutes
Thennnn:
162/60 = 2 hours and 41 mins
4:00 pm + 2 hours and 41 mins = 6:41 pm

Answer:
A. 74 cm
Step-by-step explanation:
First, we break the rhombus down into similar shapes,
The area of 2 triangles = The area of a square
So we take the triangle from the left and combine it with the triangle on the right, it should make a rectangle, Then calculate the area of the rectangle,
10 multiplied by 5 =50
Thats the area of rectangle 1
Rectangle 2
3 multiplied by 6 = 18
Triangle
4 times 3 divided by 2 = 6
Thus
6 + 18 + 50 = 74

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

Answer:
EASY DUBS:
Step-by-step explanation:
2*x-((1/4)*y) = 1 // - 1
2*x-((1/4)*y)-1 = 0
2*x+(-1/4)*y-1 = 0
2*x-1/4*y-1 = 0 // + -1/4*y-1
2*x = -(-1/4*y-1) // : 2
x = (-(-1/4*y-1))/2
x = (1-(-1/4*y))/2
x = (1-(-1/4*y))/2
