r number. Let x represent the smaller number and y represent the larger number. Which equations represent this situation?
A) y = -4/3 x + 31.
y = 2 x + 7.

B) y = -4/3 x + 31/3
y = 2 x + 7.

C) y = -4/3 x + 31.
y = -2 x + 7.

What is the dollar value of 10 nickels and 3 quarters? What is the dollar value of 2
mixer [17]

Answer:

  • 10 nickles × 5 cents value = 50 cents
  • 3 quarter × 25 cents value = 75 cents
  • So the dollar value is $1.25
  1. Now for dollar value of 2 nickles and y quarters
  2. it would be (2×5)+(y×0.25 )
  3. Hence: 10+0.25y

Use compatible numbers to estimate the quotient. 5,590 divided by 72
laila [671]

Since

7 * 8 = 56

a good place to start could be

70 * 80 = 5,600

Then

72 * 80 = (70 + 2) * 80 = (70 * 80) + (2 * 80)

= 5,600 + 160 = 5,760

This number is larger than 5,590, so let's pick another factor smaller than 80 by subtracting away as many 72s as we need:

5,760 - 72 = 5,688 = 72 * 79

5,688 - 72 = 5,616 = 72 * 78

5,616 - 72 = 5,544 = 72 * 77

So the quotient is 77, and we have

5,590 = (72 * 77) + 46

HELP! What is the equation? WILL GIVE BRAINLIEST!
Ber [7]

Answer:

The Answer is: y = x - 5

Step-by-step explanation:

Given Equation: y = x - 3

The slope is 1. Parallel lines have the same slope so m = 1.

Given point: (3, -2)

Use the Point Slope version of the equation and Substitute:

y - y1 = m(x - x1)

y - (-2) = 1(x - 3)

y + 2 = x - 3

y = x - 5

Proof:

f(3) = 3 - 5

= -2, giving (3, -2)

Hope this Helps! Have an Awesome Day!! :-)
