Step-by-step explanation:

12 - 9 + c = 12

-9 + c = 12 - 12

- 9 + c = 0

Therefore c = 9

Hope this helps.!

Answer:

c=9

Step-by-step explanation:

To solve, we must isolate the variable, c

12-9+c=12

Combine like terms (subtract 9 from 12)

3+c=12

Subtract 3 from both sides to "reverse" the addition being done to c

c=9

Answer:

68

Step-by-step explanation:

Find the vanilla first by dividing 420 by 7 and multiplying the quotient by 2 to get 120.

Then find the banana using the equation 35/100 = x/420, cross multiply to get 147.

Add 120 and 147 to get 267.

Subtract 267 from 420 to get 153.

Divide 153 by 9 to get 17.

Help asap!! interpret the meaning of the expression
Triss [41]

Answer:

D

Step-by-step explanation:

This is exponential growth, and to my understanding, the format goes:

<em>initial amount (percent growth/ decay)^time</em>

percent growth = (<em>decimal percent + 1)</em>

<em>percent decay = (1 - decimal percent) </em>

Your equation:

1500(1.02)^t

Using the above format, 1500 appears to be the initial amount, which increases by 2% per annum.

Answer:

17. y=1/2x+5

18. y=-2x+15

19. y=2x-7

Step-by-step explanation:

Number 17.

(4,7); parallel to y=1/2x-1

You know that lines that are parallel to each other have the same slope, so the slope is 1/2x.

1. Use the point-slope formula to solve for the slope-intercept equation.

y-y1=m(x-x1)

m= 1/2

x= 4

y= 7

y-7= 1/2(x-4)

y-7= 1/2x-2

y=1/2x+5

Number 18.

(4,7); perpendicular to y=1/2x-1

You know that lines that are perpendicular to each other have the opposite reciprocal slope, so the slope is -2.

1. Use the point-slope formula to solve for the slope-intercept equation.

y-y1=m(x-x1)

m= -2

x= 4

y= 7

y-7=-2(x-4)

y-7=-2x+8

y=-2x+15

Number 19.

f(3)=-1

f(4)=1

To write a linear equation, first find the slope with the slope formula.

x1= 3

y1= -1

x2= 4

y2=1

(y2-y1)/(x2-x1)

(1-(-1))/(4-3)

2/1

m=2

Use the point-slope formula and solve for the slope-intercept equation.

y-y1=m(x-x1)

y-1=2(x-4)

y-1=2x-8

y=2x-7
