How many solutions does the following system of equations have? y=5/2x+2 2y= 5x +4

goldfiish [28.3K]

Answer:

infinite solutions

Step-by-step explanation:

y=5/2x+2

2y= 5x +4

Multiply the first equation by 2

y = 5/2 x +2

2y = 5/2 *2 x +2 *2

2y = 5x +4

Since this is identical to the second equation (they are the same), the system of equations has infinite solutions

A rock is released from rest and freely falls 70 m to the ground. What is its velocity just before impact? A. 1.2 m/s B. 7.0 m/s

Yuri [45]

Answer:

37.04 m/s

Step-by-step explanation:

we can use the equation x = x0 + v0t + 1/2at^2

a = -9.8 m/s^2, the acceleration due to gravity

x0 = 70 m, the starting point of x

v0 = 0 m/s

x = 0

this will allow us to solve for time

0 = 70 + 0 +-4.9t^2

t = 3.779

now we can use the equation v = v0 + at

v = 0 + 9.8(3.77)

v = 37.04 m/s

Evaluate the expression 8 power of 2+3.8-10 times 2

Nitella [24]

Use PEMDAS:

P Parentheses first

E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)

AS Addition and Subtraction (left-to-right)

-----------------------------------------------------------------------

$8^2+3.8-10\cdot2=64+3.8-20=67.8-20=47.8$

SOLUTION

Step 1: Find the area of the wall.

$\begin{gathered} A=l\times b \\ A=42\times25.5 \\ A=1071ft^2 \end{gathered}$

Step 2: Find the cost of wallpaper per square foot

$=\frac{total\text{ cost of wallpaper}}{Area\text{ of the wall}}$ $\begin{gathered} =\frac{771.12}{1071} \\ =0.72\text{ dollars} \end{gathered}$

The correct answer is B: $0.72
