What is the slope of the line by the equations below? y-9=15 (x-5)

Answers

Answer:

Use the slope-intercept form

to find the slope

Step-by-step explanation:

Cuz i know all that

To find the slope, you should rearrange the equation into slope-intercept form, ie. y = mx + c, where m is the gradient.

y - 9 = 15(x - 5)

y = 15(x - 5) + 9 (Add 9 to each side)

y = 15x - 15*5 + 9 (Expand 15(x - 5))

y = 15x - 75 + 9

y = 15x - 66

Therefor, the slope of the equation is 15.

A container holds a combination of dimes and quarters. There are 178 coins in all, and their total value is $29.80. The system of equations models this situation, where x is the number of dimes and y is the number of quarters.x+y=178
0.1x+0.25y=29.8
How many dimes and quarters are in the container?

A.
123 dimes and 55 quarters

B.
114 dimes and 64 quarters

C.
102 dimes and 76 quarters

D.
98 dimes and 80 quarters

Answers

x+y=178

0.1x+0.25y=29.8

Solve x+y =178 for x

Add -y to both sides

x+y+-y=178+-y

x= -y+178

Substitute -y+178 for x in 0.1x+0.25y=29.8

0.1x+0.25y=29.8

0.1(-y+178)+0.25y=29.8

Simplify both sides of the equation

0.15y+17.8=29.8

Add -17.8 to both sides

0.15y+17.8+-17.8=29.8+-17.8

0.15y=12

Divide both sides by 0.15

0.15y/0.15= 12/0.15

y=80

Substitute 80 for y in x = -y+178

x= -y+178

x= -80+178

Simplify both sides of the equation

x= 98

Answer: D

x=98 and y= 80

I hope that's help !
