For questions 1-2, find the x- and y- intercept of the line. 1. -10x+5y=40 a. x-intercept is 5; y-intercept is -10. b. x-intercept is 8; y-intercept is -4. c. x-intercept is -10; y-intercept is 5. d. x-intercept is -4; y-intercept is 8. --> answer 2. 5x+4y=80 a. x-intercept is 4; y-intercept is 5. b. x-intercept is 20; y-intercept is 16. c. x-intercept is 5; y-intercept is 4. d. x-intercept is 16; y-intercept is 20. --> answer 3. write y=1/6x+4 in standard form using integers. a. -x-6y=24 b. -x+6y=24 --> answer c. -x+6y=4 d. 6x-y=24 the grocery store sells kumquats for $4.75 a pound and asian pears for $2.25 a pound. write an equation in standard form for the weights of kumquats k and asian pears p that a customer could buy with $22. a. 4.75k+2.25p=22 --> answer b. 4.75k=2.25p+22 c. 4.75+2.25=k d. 4.75p+2.25k=22 x = -2 answer is d

1. d. x-intercept is -4; y-intercept is 8.

2.d. x-intercept is 16; y-intercept is 20

3. b. -x+6y=24

4.  a. 4.75k+2.25p=22

Step-by-step explanation:

1. -10x+5y=40

to find the y intercept   let x =0

5y = 40

divide by 5

y = 40/5  = 8

to find the x intercept   let y =0

-10x = 40

divide by -10

x = 40/-10

x=-4

2. 5x+4y=80

to find the y intercept   let x =0

4y = 80

divide by 4

y = 80/4  = 20

to find the x intercept   let y =0

5x = 80

divide by 5

x = 80/5  

x=16

3. Write y=1/6x+4 in standard form using integers.

Ax+by =c

multiply each side by 6

6y = 6* (1/6 x + 4)

6y = x+24

subtract x from each side

-x+6y = x-x+24

-x +6y = 24

4. lbs of kumquats * price/per + lbs of pears * price/lb =22

 k * 4.75 + p * 2.25 =22

4.75k + 2.75p = 22

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

answer: when you burn wood, the carbon reacts with the oxygen in the air to create ash and smoke. that is a permanent change you cannot undo that.
