Answer:
Step-by-step explanation:
y2-y1/x2-x1
1+3
3-1
your slope is 4/2 or 2. keep going down to find what y is when x is 0, which happens to be -5
so now you have a slope and a y intercept you can solve like y=mx+b where m is your slope and B is your y intercept
y=2x-5 is your answer
Answer:
C = 5x + 8y + 15z + 1.5r + 15
Where C = cost for the family of 6
Step-by-step explanation:
Let:
x = number of children under 10
y = number of children 11-16
z = number of all others (16 and above)
r = number of rides
Cost:
Under 10 = $5
11-16 = $8
Above 16 = $15
Ticket Ride = $1.50
We have an additional $15 for parking
So from there, we can find the cost by getting the total:
Cost for each TOTAL
x x $5 $5x
y x $8 $8y
z x $15 $15z
r x $1.50 $1.50r
Constant : $15 for parking
So the expression would then be:
C = 5x + 8y + 15z + 1.5r + 15
Given:
6 family members
x = 3
y = 1
z = 2
r = 5
We fill in the formula
C = 5x + 8y + 15z + 1.5r + 15
C = 5(3) + 8(1) + 15(2) + 1.5(5) + 15
C = 15 + 8 + 30 + 7.5 + 15
C = 75.50
I would love to help but how can we help if we can not see the images ?
Answer:
yes! I hope this helps and I hope it's correct I'm and pretty sure it is.
Answer:
the area of the triangle is 17.4cm^2
Step-by-step explanation:
Finding the area of a triangle
an isosceles triangle has two sides of equal length.
therefore to get the base of the triangle :
we need to subtract the lengths from he perimeter
30-12-12
= 6
<u>the base of the triangle is 6 cm</u>
<u></u>
<h3><u>area of a triangle</u></h3>
formula :
<h3><u>getting the height of the triangle:</u></h3>
we make use of one side of the triangle , half the base. this creates a right angled triangle
we can make use of the formula
were c is the hypotenuse of 12 cm
a is the adjacent of base (6/2) = 3 cm
and b is the height
b = 11.6 cm to 3sf
<u>the height is 11.6cm.</u>
<u></u>
<em>area of the triangle is :</em>
1/2 * 3 * 11.6
<u>= 17.4 cm^2</u>
<u />
<u>the area of the triangle is 17.4cm^2</u>
