assuming the scale is by 1,
a) the slope is rise/run so it rises 3 units and moves 4 units right therefore the slope is 3/4
b) the y intercept is where the line crosses the y axis so by looking at the graph you can tell that the y int is 1
c) and the equation is made up of the slope and the y intercept: y= 3/4x + 1
Answer:
Step-by-step explanation:
Let the price for children and adults package be represented with x and y respectively.
For the first week the sum of the package will be as follows:
3x+8y = 126
For the two weeks after:
6x+4y= 108
So, we will be having two equations
3x+8y = 126..... (1)
6x+4y= 108.......(2)
These are simultaneous equations
From equation 1
3x+8y = 126
3x = 126-8y
X = 126-8y/3 ............. (3)
Put equation 3 into 2
6 ( 126-8y)/3 +4y = 108
756-48y/3 +4y = 108
756-48y+12y/3 = 108
Cross multiplying
756-48y+12y= 108×3
756-48y+ 12y = 324
Collecting like terms
756-324 = 48y-12y
432= 36y
Divide both sides by 36
432/36 = 36y/36
y= 12
Substituting y into equation 1
3x+8= 126
3x+96=126
3x= 126-96
3x= 30
Divide both sides by 3
3x/3 = 30/3
x = 10
Hence for each of the packages for children and adults. It will be 10 and 12 respectively.
No because it doesn't make sense <span />
Answer:
280
Step-by-step explanation:
70x4=280
Distribute -2(x - 3)
4x - 2x + 6 = 10 + -9
Simplify
2x = -5
x = -2.5
