There are 276 nickels. How many whole dollars can be made from this and with how many nickels left over?

cupoosta [38]

1 nickel = 5 cents
1 dollar = 20 nickels

You can make 13 dollars plus 16 nickels left over

20 * 13 = 260
then 260 + 16 = 276

Answer: y = 3x + 1

Step-by-step explanation:

The equation is in Slope-Intercept format: y = mx + b where

m is the slope (difference in y's over difference in x's)
b is the y-intercept (value of y when x = 0)

$m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\\\text{Let }(x_1,y_1)=(0,1)\quad \text{and}\quad \text{let }(x_2, y_2)=(1,4)\quad then\\\\m=\dfrac{4-1}{1-0}=\dfrac{3}{1}=3$

b = 1 refer to the table that shows y = 1 when x = 0

Now input m = 3 and b = 1 into the Slope-Intercept formula:

y = 3x + 1

Solve the system of equations by substitution. What is the solution for x? 2x + y = 1 4x + 2y = −1

lapo4ka [179]

Solve your system of equations.

2x+y=1;4x+2y=−1

Solve 2x+y=1 for y:

2x+y+−2x=1+−2x(Add -2x to both sides)

y=−2x+1

Substitute (−2x+1) for y in 4x+2y=−1:

4x+2y=−1

4x+2(−2x+1)=−1

2=−1(Simplify both sides of the equation)

2+−2=−1+−2(Add -2 to both sides)

0=−3

Answer: No solution. C)

Each statement describes a transformation of the graph of y = x. Which statement correctly describes the graph of y = x + 10?

scoray [572]

Answer:

Step-by-step explanation:

since it is the slope form y = mx+b

b = y axis

so in order to go up you have to translate upwards

hope this helped ;)
