2x+y = 4
2y = 6- 2x

Answers

you can graph it with the calculator or on graph paper and see where the two lines would cross
you would put them in slope-intercept form (y=mx+b)

so
2x + y = 4 would become
y = -2x + 4

and

2y = 6 - 2x becomes
y = -x +3

graph them and see where they cross. hope this helps!!

Dylan makes $336 for 32 hours of work, and Angela makes $420 for 42 hours of work.

1] How much do Dylan and Angela each make per hour?

2] Is Dylan’s wage for 25 hours proportional to Amber’s wage for 42 hours? Why or why not?

Answers

Answer:

Step-by-step explanation:

1 . Dylan : $336/32 hrs = 10.50/ hr Angela : $420/42hrs = $ 10.00/hr

2. No because $ 10.50x25 262.50 where ambers is 15 420 there unit rate is different.

Dylan $10.5 per hour
Angela $17.5 per hour
no its not proportional because half of 50 is 25 so therefore 42 would not be prportional to 25

The partial blueprint for an office building shows one outer wall and a perpendicular inner wall. Which of the following could be the equation of the inner wall, if the outer wall is represented by the equation y = 2/5x-1

a. y= -5/2x -4
b. y= -2/5x-4
c. y=5/2x-4
d. y=2/5x-4​

Answers

Answer:

a. y= -5/2x -4

Step-by-step explanation:

An equation that is perpendicular to another equation must have the opposite slope. In other words, the perpendicular equation will be the opposite sign & the reciprocal of the equation it is perpendicular to. In this case, the perpendicular slope is -5/2x. Therefore, the only answer possible is a.

Mary has a bag with 80 pieces of candy. She gives ¼ of her candy to John and 10% to Lisa. How much more candy did she give to John then Lisa?

Answers

Answer:

12 pieces

Step-by-step explanation:

80 pieces of candy

1/4 is 25% or 20 pieces of candy

10% would be 8 pieces of candy

subtract the two. Your answer is 12

Answer:

He had 14 more pieces

Step-by-step explanation:

So 80/4 is 20 pieces. So we know John has 20. Now she has 60 left since 80-20 is 60. Now 10 percent of 60 would be 6 pieces. We can subtract 6 from 20 to find out how many more pieces John had. 20-6 is 14. So John had 14 more than Lisa

If 40x = 400, then A. x equals 100. B. x equals 10. C. I equals 4. O D. x equals 1. E. requals 0 ).​

Answers

Answer:

B- x= 10

Step-by-step explanation:

40x=400 ->  40 x 10= 400

The value of x in the expression 40x = 400 by combining like terms would be 10. Hence, option B is true.

Given that,

The expression is,

40x = 400

Used the concept of expression by combining like terms.

Here, the expression is,

40x = 400

Divide both sides by 40,

x = 400/40

Therefore, the solution of x is,

x = 10

So, Option B is true.

Can someone help me figure out what are the two checkpoints?

Answers

Answer:

13,000 ft.

Step-by-step explanation:

X -------10960----------C---------------D---------------Y

The entire race (from X to Y) is 7 miles.  There are 5,280 ft. in one mile, so 7 miles is 36960 ft.

If we subtract 10,960 from 36,960, then we get the distance from C to Y.

36960-10960 = 26000

They tell you D is at the midpoint between C and Y

So if we divide 26,000 by 2, then we know the distance from C to D and from D to Y.

26000/2 = 13000

The checkpoints are C and D, so the distance between them is 13,000 ft.

The third option is correct: 13,000 feet

Answers

Answer:

x₁ = 5

x₂ = - 2

Step-by-step explanation:

Hi there !

x² - 3x - 10 = 0

x² + 2x - 5x - 10 = 0

x(x + 2) - 5(x + 2) = 0

(x - 5)(x + 2) = 0

x - 5 = 0 => x₁ = 5

x + 2 = 0 => x₂ = - 2
