Answer:
12.32
Step-by-step explanation:
So by using y1 +y2/x1+x2 we can find the ratio.
the y1 will be 4 and y2 will be 13.
the x1 will be 5 and x2 will be 6
this is equivilent to 17/11 (4+13/5+6)
17/11 =1.54545454... we can simplify to 1.54
8*1.54=12.32
this might be wrong I haven't done this math in years

Step-by-step explanation:
Let the cost of the boogie board be represented by x.
The surfboard cost six times the boogie board. Therefore, surfboard =6x
The wetsuit is $300 less than the surfboard. This means wetsuit = 6x - 300
Together a boogie board, surfboard, and wetsuit cost $1,312. Therefore,
x + 6x + 6x - 300 = 1312
13x = 1312 + 300
13x = 1612
x= 1612 / 13
x = 124
Boogie board cost $124
Surfboard = 6x
= 6 × $124
= $744
Wetsuit = 6x - 300
= $744 - $300
= $444

Answer:
<--------o o------------->
-4 2
Step-by-step explanation:
Because the sign in the inequalities is only greater than/ less than (not equal to), we know that there is an open dot on x=-4 and on x=2.
From there, we shade the area on the graph that is true to the function. So, we can test points.
First we will test x=-5
-5<-4 --> this is true, so we will shade to the left of x=-4
Now test x=0
0<-4 --> this is false
0>2 --> this is also false, so the area between the two open dots will not be shaded
Now test x=3
3>2 --> this is true, so we will shade to the right of x=3
