Answer:
x = -11, y = -2
Step-by-step explanation:
There's two equations. Let's say the first number is x, and the second number is y. Then, there is 4y-3 = x, and 2y-x = 7. We plug in 4y-3 for x into the second equation, and we get 2y - (4y-3) = 7. Solving more gets us -2y + 3 = 7. thus, -2y = 4, meaning y = -2. We plug back into the second equation, getting -4 - x = 7. This 11 = -x, or x = -11.

Find the value of y in the solution to the system of equations shown. y=5x+3 2y=18x-10
Answer:
13
Step-by-step explanation:
To find the value of y, we will use the substitution method
Plug the y of the top equation into the other equation
2(5x + 3) = 18x - 10
Distribute the 2 into the equation inside the parenthesis
10x + 6 = 18x - 10
Subtract 10x from both sides
10x + 6 = 18x - 10
-10x -10x
6 = 8x - 10
Add 10 to both sides
6 = 8x - 10
+10 + 10
16 = 8x
Divide both sides by 8
16/8 = 8x/8
x = 2
Sub the 2 in the place of x into one of the original equations. We will use the first one.
y = 5(2) + 3
y= 10 + 3
y = 13
Answer:
y = 13
Step-by-step explanation:
y = 5x + 3
2y = 18x- 10
substitution (substituting y with the y value given):
2( 5x + 3 ) = 18x - 10
solve:
10x + 6 = 18x - 10
10x - 18x = -10 - 6
-8x = -16
x = 2
now plug in the x:
y = 5( 2) + 3
y = 10 + 3
y = 13

Step-by-step explanation:
as the question told you, if there're 5 counselors, there's a maximum for students of 15. and for 15 counselors, there's a maximum for students of 45. we can easily see that every one counselor can only have 3 students. therefore, you should draw each dot with respect to the counselors' amount, but because two points determine one line, all you need to do is draw (5,15), (15,45) and line them from 0 to 50.
Pat’s Pizza Place sells large pies for $12 with a charge of $2 for each topping. If Reagan only has a $20 bill to spend on a pizza, which graph best represents the number of toppings she can afford to add to her pie? A number line going from 2 to 7. A solid circle is at 4. Everything to the left of the circle is shaded. A number line going from 2 to 7. A solid circle is at 4. Everything to the right of the circle is shaded. A number line going from 2 to 7. A solid circle is at 6. Everything to the left of the circle is shaded. A number line going from 2 to 7. A solid circle is at 6. Everything to the right of the circle is shaded.
Answer:
A number line going from 2 to 7. A solid circle is at 4. Everything to the left of the circle is shaded.
Step-by-step explanation:
The pizza itself will cost $12, and because toppings cost $2 apiece, the maximum amount of toppings that can be used is 4.
4·2=8
8+12=20
So, by putting a closed circle on 4, going to the left, the line shows that she can buy anywhere from 0-4 topping on her pizza.

Triangle P Q R is shown. Angle P Q R is a right angle. The length of Q R is p, the length of R P is q, and the length of P Q is r. Which sine ratios are correct for ΔPQR? Check all that apply.
A. sin (P) = StartFraction r Over q EndFraction
B. sin (P) = StartFraction p Over q EndFraction
C. sin (Q) = StartFraction r Over p EndFraction
D. sin (R) = StartFraction q Over r EndFraction
E. sin (R) = StartFraction r Over q EndFraction
Step-by-step explanation:
answer is in the picture
Option A (sin(P) = r/q), Option C (sin(Q) = r/p), and Option D (sin(R) = q/r) are correct sine ratios for ΔPQR. Option B (sin(P) = p/q) and Option E (sin(R) = r/q) are not correct sine ratios for ΔPQR.
To determine the correct sine ratios for ΔPQR, let's recall the definitions of sine for each angle in a right-angled triangle.
In a right-angled triangle ΔPQR:
1. sin(P) = opposite side / hypotenuse = r / q (Correct) [By definition of sine in a right triangle, sin(P) = opposite/hypotenuse]
2. sin(Q) = opposite side / hypotenuse = r / p (Correct) [By definition of sine in a right triangle, sin(Q) = opposite/hypotenuse]
3. sin(R) = opposite side / hypotenuse = q / r (Correct) [By definition of sine in a right triangle, sin(R) = opposite/hypotenuse]
Option A (sin(P) = r/q), Option C (sin(Q) = r/p), and Option D (sin(R) = q/r) are correct sine ratios for ΔPQR. Option B (sin(P) = p/q) and Option E (sin(R) = r/q) are not correct sine ratios for ΔPQR.

How many committees can be formed by choosing 4 men from an organization of a membership of 15 men?
The selection of the committee members is an illustration of combination
There are 150150 different ways of selecting the committee
How to determine the total selectionThe number of members (n) is:
n = 15
The members on the committee are (r):
r = 4
So, the number of selection is:
[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]
This gives
[tex]^{15}C_4 = \frac{15!}{(15 - 4)!4!}[/tex]
Evaluate the differences
[tex]^{15}C_4 = \frac{15!}{9!4!}[/tex]
Expand
[tex]^{15}C_4 = \frac{15* 14 * 13 * 12 * 11 * 10 * 9!}{9!4!}[/tex]
This gives
[tex]^{15}C_4 = \frac{15* 14 * 13 * 12 * 11 * 10}{4!}[/tex]
[tex]^{15}C_4 = 150150[/tex]
