Answer: -8x^2 + 62y^2 + 46
Answer:
- Keisha is right.
- No, only 1 ratio works
Step-by-step explanation:
- You want the units to be dollars / mango.
- You have 10 dollars. How many mangos can you buy and at what price. They are selling mangoes for more than a dollar each.
- The answer should be $1.25 per mango. Think of it this way:
- If the cost of a mango was $1.00 you would be able to get 10 of them. Do you agree? Since you can only get 8, they must be more than a dollar each.
- The ratio can only be written in one way. 10/8 = 1.25
Answer
- Keisha is right.
- No, only 1 ratio works

Answer:
y = 3x + 6
Step-by-step explanation:
y2 - y1 / x2 - x1
9 - (-6) / 1 - (-4)
15/5
= 3
y = 3x + b
9 = 3(1) + b
9 = 3 + b
6 = b
Answer:
x = 12
m(QS) = 52°
m(PD) = 152°
Step-by-step explanation:
Recall: Angle formed by two secants outside a circle = ½(the difference of the intercepted arcs)
Thus:
m<R = ½[m(PD) - m(QS)]
50° = ½[(12x + 8) - (4x + 4)] => substitution
Solve for x
Multiply both sides by 2
2*50 = (12x + 8) - (4x + 4)
100 = (12x + 8) - (4x + 4)
100 = 12x + 8 - 4x - 4 (distributive property)
Add like terms
100 = 8x + 4
100 - 4 = 8x
96 = 8x
96/8 = x
12 = x
x = 12
✔️m(QS) = 4x + 4 = 4(12) + 4 = 52°
✔️m(PD) = 12x + 8 = 12(12) + 8 = 152°
