Step-by-step explanation:
In a general linear function, the formula is this: y = mx + c, where m is the gradient and c is the y-intercept.
Answer:
The true statement is: In step 3 she needed to subtract c rather than divide.
Step-by-step explanation:
Lets solve our equation step by step.
Step 1. Since 3 is the denominator of the right hand side, we need to multiply both sides of the equation by 3:
Now we can cancel the 3 in the numerator and the 3 in the denominator to get
As you can see, the first statement is false
Step 2. Since we want to isolate the variable , we need to subtract b from both sides of the equation:
The second statement is also false
Step 3. The last thing we to do to isolate (and solve for it) is subtract c from both sides of the equation:
Therefore, the third statement is true: In step 3 she needed to subtract c rather than divide.
Answer:
A. Pontiac
Step-by-step explanation:
Camry's mileage = Miles travelled / gallons of fuel used
= 196 / 11
= 17.82
Pontiacs mileage = Miles travelled / gallons of fuel used
= 220 / 13
= 16.92
Bluck's mileage = Miles travelled / gallons of fuel used
= 356 / 15
= 22.25
Toyotas mileage = Miles travelled / gallons of fuel used
= 583 / 21
= 27.76
The car with the best mileage is Pontiac
