Answer:
The answer to your question is x = 64; y = 20
Step-by-step explanation:
Angles 2x + 2 and 130° are vertical angles so they measure the same.
2x + 2 = 130
- Solve for x
2x = 130 - 2
2x = 128
x = 128/2
x = 64
Angles 3y - 10 and 50° are vertical angles, so they measure the same.
3y - 10 = 50
3y = 50 + 10
3y = 60
y = 60/3
y = 20
The answer is forty inches
Answer:
1750 tickets
Step-by-step explanation:
100 x 14 is 1400, so 125 x 14 will be the answer. 125 x 14 = 1,750. The answer is 1,750 tickets.
Answer:
Step-by-step explanation:
1) First, find the slope of the line. Take two points the line intersects and use them for the slope formula, 
. We already know the line intersects (-4, -2). Just choose any one of the points you can see the line intersecting (in this case, I chose (0,3)) and plug in its values, too. Then solve:
So, the slope is 
.
2) Now that you have the slope, plug in values for the point-slope formula, 
. In order to write a linear equation with it, the 
, 
, and 
have to be substituted for with real values. The represents the slope - which means that we should place there. The and represent the x and y values of a point - and the questions wants us to use (-4, -2), so substitute -4 for and -2 for :
Thus, the answer is .
so this is very simple.
if f(x)=12x +50, and we want to know how much the cost goes up per square yard, we look at the relationship.
if the coefficient of x is 12, the cost will go up $12 per square yard.
it is NOT 62 because the 50 is a one time thing that is only added one time. think about it like having the price be $50 at 0 yards. it's almost like a flat fee. for 1 yard its 62, 2 its 74, etc. it goes up 12 each time. additionally, it's not x because x is the amount of yards, not the cost of a yard. it is not 50 because 50 is added, and is not in relationship to x.
so, the answer is b.
hope I helped.
