Nancy bought 177 long sleeve and 354 short sleeve shirts.

{x+y=531, y=2x} represents the system of equations for this problem.

Step-by-step explanation:

Let,

x be the long sleeve shirts

y be the short sleeve shirts

Total shirts bought = 531

According to given statement;

x+y=531   Eqn 1

y = 2x  Eqn 2

Putting value of y from Eqn 2 in Eqn 1;

x+2x=531\\3x=531

Dividing both sides by 3;

\frac{3x}{3}=\frac{531}{3}\\x=177

Putting x=177 in Eqn 2

y=2(177)\\y=354

Nancy bought 177 long sleeve and 354 short sleeve shirts.

{x+y=531, y=2x} represents the system of equations for this problem.

The vertex of a parabola is ( 3, -1). One point on the parabola is
Rudik [331]

Answer:

Step-by-step explanation:

If you plot the vertex and the point, you see that the point is above the vertex. Therefore, this is a positive parabola with the work form of

y=a(x-h)^2+k

We have values for x, y, h, and k. Let's write the equation of the parabola, put it into function notation, then find another x value at which to evaluate it.

8=a(6-3)^2-1 and

8=a(3)^2-1 and

8 = 9a - 1 and

9 = 9a so

a = 1. The equation of the parabola in function notation is

f(x)=(x-3)^2-1

Since the vertex is at (3, -1) it would make sense to evaluate the function at x values close to the vertex. Let's evaluate the function at an x value of 4:

f(4)=(4-3)^2-1 and

f(4)=(1)^1-1 and

f(4) = 0. That means that another point on this parabola will be (4, 0).

Answer:

64 cubic feet.

Step-by-step explanation:

Volume is length times height times width.

It is all 4 feet, so it is 4 feet * 4 feet * 4 feet, or 64 cubic feet.

Geometry math question
Brut [27]

Look at the picture.

Let |AE| = |AD| = b

We have a proportion:

\dfrac{x}{13}{y}=\dfrac{19}{y+a}=\dfrac{x}{y+2a}

Solve for y from first proportion

\dfrac{13}{y}=\dfrac{19}{y+a}\ \ \ |\text{cross multiply}\\\\19y=13(y+a)\\\\19y=13y+13a\ \ \ \ |-13y\\\\6y=13a\ \ \ |:6\\\\y=\dfrac{13}{6}a

Substitute to the second proportion

\dfrac{19}{y+a}=\dfrac{x}{y+2a}\\\downarrow\\\dfrac{19}{\frac{13}{6}a+a}=\dfrac{x}{\frac{13}{6}a+2a}\\\\\dfrac{19}{\frac{13}{6}a+\frac{6}{6}a}=\dfrac{x}{\frac{13}{6}a+\frac{12}{6}a}\\\\\dfrac{19}{\frac{19}{6}a}=\dfrac{x}{\frac{25}{6}a}\ \ \ \ |\dot a\neq0\\\\\dfrac{19}{\frac{19}{6}}=\dfrac{x}{\frac{25}{6}}\\\\19\cdot\dfrac{6}{19}=x\cdot\dfrac{6}{25}\\\\6=\dfrac{6x}{25}\ \ \ |\cdot25\\\\6x=6\cdot25\ \ \ |:6\\\\x=25

Answer: B. 25
