Answer:
y = (-2/11)x + 110
Step-by-step explanation:
First, find the slope of the points: (y2 - y1)/(x2 - x1) = m
(-5 - -3)/(4 - -7) which is also represented as (-5 + 3)/(4 + 7).
m = -2/11
Then, plug in the slope and one point in the slope-intercept form:
y = mx + b
-5 = -2/11(4) + b
110 = b
Finally, turn it into a general equation:
y = (-2/11)x + 110
Answer:
5
Step-by-step explanation:
f(4) falls into the category x > -1 because 4 > -1. Therefore, we use the function f(x) = 2x - 3. f(4) will then equal 2(4) - 3 = 5.
5/8
Step-by-step explanation:
Probability of raining = 3/8
Total days= 8/8
Then probability of not raining= 8/8 - 3/8
= 5/8
Answer:
12 cupcakes
Step-by-step explanation:
There are 36 cupcakes but she only use 3 kinds of icing and you want to find how many cupcakes is 1/3 in 36 so you divide by 3
The triangles are similar so corresponding sides will be in ratio. The first triangle has sides of 2, 4, and 6. The second triangle has a largest side of 24. You are asked to find the perimeter of the second triangle.
The largest side of the first triangle is 6 and the largest side of the second triangle is 24. This is a ratio of 6:24 which can be reduced to 1:4.
Each side of the second triangle is 4 times as large as the corresponding side of the first triangle.
Now we can calculate the other 2 sides.
2 x 4 = 8
4 x 4 = 16
The three sides are 8, 16 and 24
Perimeter of this triangle is 8 + 16 + 24 = 48
