Answer:
1. 0.75 cm to 1 km
4. 0.3 mm to 40 m
Step-by-step explanation:
we have the scale
<u><em>Verify each case</em></u>
case 1) 0.75 cm to 1 km
therefore
The scale is equivalent to the given value
case 2) 1 cm to 12 km
therefore
The scale is not equivalent to the given value
case 3) 6 mm to 2 km
Remember that
1 cm= 10 mm
1 mm=0.1 cm
we have
therefore
The scale is not equivalent to the given value
case 4) 0.3 mm to 40 m
Remember that
1 cm= 10 mm -----> 1 mm=0.1 cm
1 km=1,000 m ----> 1 m=0.001 km
we have
therefore
The scale is equivalent to the given value
case 4) 1 inch to 7.62 km
Remember that
1 in= 2.54 cm
we have
therefore
The scale is not equivalent to the given value
Answer:
y = -2x - 14
Step-by-step explanation:
Slope intercept form: y = mx + b
2x + y = - 14
y = -2x - 14
Answer:
This is not a linear function.
Step-by-step explanation:
It is a quadratic function. If you were to make a table of the x and y values of the function it would look like this:
x y
0 -4
1 -1
2 8
Just by looking at these three values, we can see that they do not increase at a consistent rate. It increases by 3 from 0 to 1, but increase by 9 from 1 to 2. You can tell if a function is linear by seeing if it increases at a constant rate. (In this case it does not)
13.80 x 2= 27.60
1 pizza equals 13.80 so two pizzas will be twice that money amount. Both pizzas will cost $27.60.
