Answer:

73 nickels, 27 dimes

Step-by-step explanation:

x+y=100

5x+10y=635

x=100-y

5(100-y)+10y=635

500-5y+10y=635

500+5y=635

5y=135

y=27

5x+10(27)=635

5x+270=635

5x=365

73+27=100

Convert 14x + 6y = 36 to slope intercept form.

zubka84 [21]

Answer:

y = - $\frac{7}{3}$ x + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

14x + 6y = 36 ( subtract 14x from both sides )

6y = - 14x + 36 ( divide all terms by 6 )

y = - $\frac{14}{6}$ x + 6, that is

y = - $\frac{7}{3}$ x + 6 ← in slope- intercept form

Convince me why points B&C are solutions to this system of linear inequalities.

muminat

The coordinates of B and C are solutions to the system of inequalities because both are true to the two inequalities. A is not a solution to the system of inequalities because it is only true to “y is less than or equal to 2x”.
