I’m pretty sure it’s, D, if not, it’s C, I haven’t done this in a few years so correct me if I’m wrong, but I’m more sure it’s D.
Answer:
Step-by-step explanation:
Slope-intercept formula requires us to isolate the y variable. We can do this in just a couple of steps.
1) Move 5x from the left to the right side by subtracting 5x from both sides. This cancels out the 5x on the left side, and remember, what we do to one side we must do to the other to keep the equation balanced.
2) Divide both sides by 6. Again, we are cancelling out the 6 on the left but we must also divide on the right. This would mean dividing -5 and 42 by 6 to get:
Answer:
orange: 0.2$, apple: 0.4$
Step-by-step explanation:
we mark the price of an orange x and the price of an apple y. then we write down Maggie's and Tanya's purchases as a set of equations:
10 oranges and 5 apples for 4$ means:
9 oranges and 3 apples for 3$ means:
we use the second equation to isolate y:
and plug it in the first equation:
and then we find y:
Answer: The first answer in the screenshot is correct. Sides 5, 10 and 5√3
Step-by-step explanation: In a 30°60°-90° triangle, the side opposite the 30° angle (shortest side) is half the length of the hypotenuse. So you have to choose one with 5 & 10. Use the Pythagorean theorem to calculate the remaining side a² + b² = c²
5² + b² = 10², so b² = 100-25 √b²=√75 so √(25)(3)
b= 5√3
