Answer:
2y + x = -5Step-by-step explanation:
The standard form of the equation is expressed as y = mx+c
m is the slope
c is the y-intercept
Given the coordinate points (-7, 1) and (-1,-3)
m = y2-y1/x2-x1
m = -3-1/1+7
m = -4/8
m = -1/2
Get the intercept
y = mx+c
1 = -1/2(-7) + c
1 = 7/2 + c
c = 1-7/2
c = -5/2
Get the equation
y = mx+c
y = -1/2 x - 5/2
2y = -x - 5
2y + x = -5
Hence the required equation is 2y + x = -5
what is the value of the y-coordinate of the y-intercept of the function shown below? f(x)=-4x^2+2x-5
Answer:
-5
Step-by-step explanation
Given the function f(x)=-4x^2+2x-5, the y intercept occurs at x = 0
Substitute x = 0 into the function and find y as shown;
f(x)=-4x^2+2x-5
f(0)=-(0)^2+2(0)-5
f(0)=0-5
f(0) = -5
The coordinate point is (0, -5)
Hence the value of the y coordinated is -5

The age difference between
two sisters is 6. If the ratio of
two ages is 5:7, how old are
they?
(Please Help!)
9514 1404 393
Answer:
15 and 21
Step-by-step explanation:
I like to work these considering the difference in ratio units.
The age ratio is 5 : 7.
The age difference in ratio units is 7 - 5 = 2. The difference in years is 6, so each ratio unit must be 6/2 = 3 years. Multiplying the ratio numbers by 3, we get the actual ages as ...
5 : 7 = (3·5) : (3·7) = 15 : 21
The two sisters are 15 and 21 years old.
The sum of two numbers is negative. The product of these two same numbers is also negative. What can you conclude about these two numbers? Be as specific as you can. Give an example of two numbers that meet these requirements.
Answer:
5 and -8
Step-by-step explanation:
One number must be negative since the product of the 2 number is negative (5 x -8 = -40). They both cannot be negative, if they were the product would then be positive. The negative number must have a absolute value that is larger than the positive, the negative numbers distance from 0 must be larger than the positive, -8 has a distance of 8 and 5 has a distance of 5. The sum of the two numbers is
=5 + (-8)
=5 - 8
= -3

find the radical equivalent of 27 ^ 2/3 and compute it. Explain please.
Answer: 9
Step-by-step explanation:
27 ^ 2/3 is equal to [tex](\sqrt[3]{27})^2[/tex]
3 * 3 * 3 = 27
so, [tex]\sqrt[3]{27}[/tex] = 3
3 * 3 = 9
so, [tex]3^{2}[/tex] = 9
Brent bought 6 packages of Kool-Aid mix priced at for $0.29 each and 2 packages of Sugar priced at $3.92 each and a gallon of water for $0.95. What is the total amount she spent, on the Kool-Aid and Sugar?
Answer:
kool-aid - $1.74
Sugar - $7.84
Total =$9.58
Step-by-step explanation:
kool-aid = $ 0.29 × 6 = 1.74
×6 because she bought 6 packages of Kool-aid and the price of each was $0.29
sugar = $3.92×2 = 7.84
×2 because she bought 2 packages of sugar and price for each was $3.92
total = $9.58
Add $1.74 + $7.84
Laura sold t-shirts at a festival. She made $6 for each t-shirt she sold. Her expenses were $30. If she made a profit of $84, how many t-shirts did she sell?
(a) Write an equation that could be used to answer the question above.
First, choose the appropriate form. Then, fill in the blanks with the
numbers 6, 30, and 84. Let x represent the number of t-shirts.
Answer:
The equation is:
[tex]x=\frac{Total\:Expenses+Profit}{Cost\:of\:1\:shirt}[/tex]
Solving we get: Laura sold 19 shirts in the festival.
Step-by-step explanation:
Cost of 1 shirt = $6
Total expenses = $30
Profit made = $84.
We need to write equations that helps in finding the number of t-shirts Laura sold.
Let x= represents number of t-shirts
Since profit was $84, and expense was $30
So, Total money earned = Total expense + Profit
Now, 1 shirt cost 6 dollars, so if we divide Total Money earned by 6 we can find x (the number of shirts sold)
Writing equation:
[tex]\mathbf{x=\frac{Total\:Expenses+Profit}{Cost\:of\:1\:shirt}}[/tex]
Putting values we can find x
[tex]x=\frac{30+84}{6}\\x=\frac{114}{6}\\x= 19[/tex]
So, Laura sold 19 shirts in the festival.

what is the correct answer?
Answer:
(C) x^3+11x^2+34x+24
Step-by-step explanation:
The volume of a rectangular prism is V=lwh
x+4=L
x+1=W
x+6=H
Thus:
(x+4)(x+1)(x+6)
(x^2+5x+4)(x+6)
x^3+5x^2+4x+6x^2+30x+24
x^3+11x^2+34x+24
Therefore, the correct answer is (C) x^3+11x^2+34x+24

can my grade go up by 14 points in one test?
Answer:
It depends on how much percent the test is worth and everything you might be missing but more than likely no you'd have to do really well on the test and a few assignments . There's a way you can calculate your grade with whatever you might be missing and the grade you're trying to get in the class.
you'd have to divide your grade in each category by 100 then multiple it by the percentage and add everything together for example:
Homework is 20% of a grade . I have a 90 in the homework category . 90/100 times 20 which will give me 18 then put the 18 over 20. 18/20
Projects are 30% of a grade. You have a 50 out of 80 do 50/80x30. which is 18.75 out of 30.
Final is 50% lets say you get a perfect score on the final meaning you get 50 points.
add 18+18.75+50= 86.75
add 20+30+50=100
you'd make a 86.75 in the class so a B. hopefully this helps . So if you need 14 points you should go to your assignments/tests and it should say how much there worth.
HELP QUESTION ONE BABABOI
Answer:
x = 0, y = 3
Step-by-step explanation:
When using graphing to solve a system of equations, the intersection point is the solution. Most points on a graph follow a certain way of writing them and it looks like this: (x, y).
Here, the coordinates of the intersection point is: (0, 3). Thus the solution would be:
(x, y)
(0, 3)
x = 0, y = 3
Which set of measurements could make a triangle?
1) 1 mm, 2 mm, 3 mm
2) 7 mm, 4 mm, 3 mm
3) 9 mm, 10 mm, 8 mm
4)11 mm 8 mm, 20 mm
help me fast please
Answer:
3.) a. 9mm b. 10mm c. 8mm
Step-by-step explanation:
All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.
Formula:
a + b = (answer) > c
a + c = (answer) > b
b + c = (answer) > a
try to solve it yourself so you can do it on your own in the future.
Below are statements that can be used to prove that the triangles are similar.
On a coordinate plane, right triangles A B C and Z Y X are shown.
1. StartFraction A B Over Z Y EndFraction = StartFraction B C Over Y X EndFraction = 2
2. ∠B and ∠Y are right angles.
3.?
4.?
Which two statements are missing in steps 3 and 4?
∠X ≅ ∠C
△ABC ~ △ZYX by the SAS similarity theorem.
∠B ≅ ∠Y
△ABC ~ △ZYX by the SAS similarity theorem.
StartFraction A C Over X Y EndFraction = 2
△ABC ~ △ZYX by the SSS similarity theorem.
StartFraction Z X Over A C EndFraction = 2
△ABC ~ △ZYX by the SSS similarity theorem.
Answer: ∠B ≅ ∠Y
△ABC ~ △ZYX by the SAS similarity theorem.

Kary needs 54 licks for every 3 lollipops she eats. Which option below will complete the table?
Licks 96, Lollipops 1
Licks 108, Lollipops 2
Licks 72, Lollipops 5
Licks 84, Lollipops 4
Answer:
The second one is correct as 108 is double 54
Step-by-step explanation:
Therefore since 54 licks gets one lollipop gone 108 would get 2 lollipops gone
The force of gravity between two objects is given in the relation: g=6.67*(10)^ -11 , k1.k2 d^ 2 Where k1 and k2 are the body masses in kilograms (kg) (d) is the distance between the two objects in meters (m).
