Let's first write down the equations which we will require to solve for this problem.
Equation No. 1 -
x km/h = y mph
Equation No. 2 -
8 km/h = 5 mph
First of all, we will make y the subject by calculating the km/h when mph = 1. We will accomplish this by dividing both sides by 5 as displayed below:
Equation No. 2 -
8 km/h = 5 mph
5 mph = 8 km/h
5 / 5 mph = 8 / 5 km/h
1 mph = 8 / 5 km/h
Through this, we have found out:
m = 8 / 5
We will use the y = mx formula in order to obtain our final equation. We will substitute the value given in the second equation into the formula.
y = mx
y = ( 8 / 5 ) x
Answer:
6
Step-by-step explanation:
B(Y)=5x+18
input the values
-2B=5(-6)+18
-2B=-30+18
-2B=-12
B=-12/-2
B=6
ANSWER: y=7x-33
EXPLANATION: Parallel lines have the same slope but different y intercepts so first turn the eq of the first line into slope intercept form by subtracting -14x and dividing by -2, we get a slope of 7 and we know a parallel line has the same slope so y=7x+b, plug in the values of x and y in the coordinates and add like terms and we get b is equal to -33 so the equation is y=7x-33
Answer:
well you used 6.4 pounds of flour to make bread which means you have 9.6 pounds left so you could make about 14 batches
