Answer:
<h2>y = -35x + 105</h2>
Step-by-step explanation:
The given graph represents a function between hours and miles.
To determine the equation that belong to this graph, first we need to find the slope using two points from the graph: (0, 105) and (3, 0).
The definition of slope is

Notice that the slope is -35. Remember that the slope is always the coefficient of variable
. So, the choice that has this slope is the right answer.
Therefore, the right answer is the last choice: y = -35x + 105
Answer:
A one solution
Step-by-step explanation:
4(x - 5) = 3x + 7
Distribute
4x - 20 = 3x+7
Subtract 3x from each side
4x-3x-20 = 3x+7-3x
x -20 = 7
Add 20 to each side
x -20+20 = 7+20
x = 27
There is one solution
Answer:
Explanation:
The pattern of the game consists on 7 congruent (necessary assumption) rectangles.
The dimensions of such congruent rectangles are given for the rectangle number 6: lenght = t + 3 (a binomial) and width = t (a monomial).
So, the area of each rectangle is found as the product of a monomial and a binomial:
Apply <u>distributive property</u>:
Since that is the area on one rectangle, you have to mulply by the number of reactangles (7):
