Y = -4/5 + 7, the 7 is the slope intercept and the -4/5 is the slope

For this case, the first thing you should do is write the generic equation of the line.
 We have then:
 y-yo = m (x-xo)
 The slope of the line will be:
 m = -4 / 5
 The ordered pair is:
 (xo, yo) = (0, 7)
 Substituting the values:
 y-7 = (- 4/5) * (x-0)
 Rewriting:
 y = (- 4/5) x + 7
 Answer:
 
An equation in slope-intercept for the line that has a slope of -4/5 and passes through (0,7) is:
 y = (- 4/5) x + 7

What two numbers multiply to get 40 and add to get 11
Trava [24]
I got the factors of 40 but both numbers do not add up to 11. Negative numbers are not considered because the product and sum are positive numbers.

1 x 40 = 40    1 + 40 = 41
2 x 20 = 40    2 + 20 = 22
4 x 10 = 40    4 + 10 = 14
5 x   8 = 40    5 +   8 = 13

I also got the addends of 11 and solved each set to get the product
1 + 10 = 11    1 x 10 = 10
2 +   9 = 11    2 x   9 = 18
3 +   8 = 11    3 x   8 = 24
4 +   7 = 11    4 x   7 = 28
5 +   6 = 11    5 x   6 = 30

Melissa, Dan, and Henry have $87 in their wallets. Dan has 3 times what Henry has. Melissa has $8 less than Henry. How much does
puteri [66]

Answer:

Henry has $19, Dan has $57, and Melissa has $11

Step-by-step explanation:

Let x represent how much money Henry has

Since Dan has 3 times what Henry has, his amount is 3x

Since Melissa has $8 less than Henry, her amount is x - 8

Create an equation that sets these 3 values equal to 87, then solve for x

(x) + (3x) + (x - 8) = 87

5x - 8 = 87

5x = 95

x = 19

So, Henry has $19

Find how much Dan has by multiplying 19 by 3

19(3)

= 57

Find how much Melissa has by subtracting 8 from 19

19 - 8

= 11

So, Henry has $19, Dan has $57, and Melissa has $11
