Answer:
b,3 hours
Step-by-step explanation:
because you have 32 times 2 is 64 in 2 hours so that is not is so the times 8 is 256 in 8 hours so that is not it then times 16 is 512 so 512 in 16 hours that's not it so then times 3 it is 96 cars in 3 hours
Lines that are perpendicular will have slopes that are opposite reciprocals. The slope of y=7/6x+4 is 7/6. So we need to find the opposite reciprocal of 7/6. Opposite would make the number negative and reciprocal would switch the numerator with the denominator. So the slope of any line reciprocal to y=7/6x+4 would be -6/7. Then you can use any real number as the y intercept for the new equation.
An acceptable answer would be
y= -6/7x+10
But the number 10 could be replaced by any real number.
It is the first one —-> y = mx
Answer:138
Step-by-step explanation:
First plug in the c and d values into the expression:
6(5)^2-5(4)+8
Remember PEMDAS, so you do 5^2 first getting you 25.
6(25)-5(4)+8
Continue with PEMDAS and multiply -5 and 4, and that gets you -20.
150-20+8
Now you simplify the expression to get: 138.
First, we must put that equation into slope form.
3x-4y=6 >> -4y= -3x+6 >> y= 3/4x-3/2
Parallel lines share the same slope, so we know that the new equation must at least look like y= 3/4x+b. However, since we must find b, we need to plug in (2,6) for the x and y coordinates to solve.
6= 3/4(2) + b
6= 6/4 + b
4.5 = b
We plug this b value into y=3/4x+b, therefore making the final new equation y= 3/4x + 4.5
