Answer:
see the explanation
Step-by-step explanation:
we know that
To calculate the slope we need to take two points from data in a table
point 1 (x1,y1) and point 2(x2,y2)
The formula to calculate the slope between two points is equal to
substitute the values and solve for m
Answer: 22 small snow cones and 34 large snow cones were sold.
Step-by-step explanation:
Let x represent the number of small snow cones that were sold.
Let y represent the number of large snow cones that were sold.
Selena's snow cone stand sells small snow cones for $2 and large snow cones for $3.50. One summer day, she sold $163 worth of snow cones. This means that
2x + 3.5y = 163 - - - - - - - - - - 1
If the number of large snow cones sold was 12 more than the number of smalls snow cones, it means that
y = x + 12
Substituting y = x + 12 into equation 1, it becomes
2x + 3.5(x + 12) = 163
2x + 3.5x + 42 = 163
5.5x = 163 - 42
5.5x = 121
x = 121/.5 = 22
y = x + 12 = 22 + 12
y = 34
Ok... Perimeter is = 2l + 2w
w being width and l being length.
We know that perimeter is equal to 400 so
400 = 2l + 2w
The length is 15 meters less than the width, so in notations, l = w - 15
We can substitute than in the equation to get 2(w-15) + 2w = 400
Expanding will give 2w - 30 + 2w = 400
Solving w gives w= 430/4 = 107.5 meters
Substituting in original equation for w to find l, 400 = 2l + 2(107.5)
400 = 2l + 215
2l = 185
l = 92.5 cm
Or you can just use the question to know that the length is 15 times less than the width, so 107.5 - 15 = 92.5
Length = 92.5 cm
Width = 107.5 cm
Answer: y = x + 8
Step-by-step explanation:
This is asking us to remove the parameter. In other words, we want an equation with only the relation between x and y, so we need to remove the t. There are a few ways to do this, but I am going to set one equation equal to t and then plug it into the next one.
Given:
x = 5t
Divide both sides of the equation by 5:
t = x
-
Given:
y = t + 8
Plug in:
y = (x) + 8
Answer:
y = x + 8
