Answer:
Slope of the line that passes through the points (1, 7) and (3, 3) = -2
Step-by-step explanation:
Given in the question two co-ordinates,
(1, 7)
(3, 3)
here x1 = 1
x2 = 3
y1 = 7
y2 = 3
Formula to use
m = ![\frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D)
= ![\frac{3-7}{3-1}](https://tex.z-dn.net/?f=%5Cfrac%7B3-7%7D%7B3-1%7D)
= -4/2
= -2
Answer:
Step-by-step explanation:
Let the larger integer = 2x + 1
Let the second integer = 2x - 1
1/2 (2x + 1 + 2x - 1) = - 12 Combine the left
1/2(4x) = - 12 Combine 1/2 (4x)
2x = - 12 Divide by 2
2x/2 = - 12/2
x = - 6
2x + 1 = 2*-6 + 1 = -11
2x - 1 = 2*-6 - 1 = - 13
Check
-11 + - 13 = - 24
1/2(-24) = -12 which checks.
Answer:
The expression 16.78d + 49 represents the amount Rita spent at the mall.
If she bought 3 itens, Rita spent $99.34.
Step-by-step explanation:
Expression:
First store: 16.78d + 23
Second store: 26
Total: 16.78d + 23 + 26 = 16.78d + 49
Then estimate how much Rita spent if she bought 3 items.
Now, we have that d = 3. So
16.78*3 + 49 = 99.34
If she bought 3 itens, Rita spent $99.34.
