Answer:
y=7/24x+625/24
Step-by-step explanation:
-7x+24y=-25"2
-7x+24y=625
+7x +7x
24y=7x+625
divide 24
y=7/24x+625/24
Got this for my mathswatch too
Answer:
Eagles
Step-by-step explanation:
2000x6=12000 this is the most
Time = Distance / Speed
T = 8.5 miles/ 22 miles = 0.3863
Answer:
31000 dollars were invested at 4% interest rate.
16000 dollars were invested at 5% interest rate.
Step-by-step explanation:
Convert the interest rate into decimal and then write down two equations to solve for the unknowns.
Best Regards!
First you normalize 3x+4y=12 into y = -3/4 x + 3 (dividing by 4).
Then you observe that the slope of the line is -3/4 (it's always the factor with the x). A perpendicular line has the reciprocal slope. Reciprocal means inverted and negated. So -3/4 becomes +4/3.
The equation will thus look like y = 4/3 x + b. To find b, we fill in the given x intercept (0,2), (we get 2 = 4/3 * 0 + b). With x=0, b must be 2.
So the equation is: y = 4/3 x + 2
