2x-3y=-15
subtract 2x from each side
-3y = -2x-15
divide by -3
y = 2/3 x +5
this is in slope (2/3) intercept (5) form
Answer:
1 Shirt costs $12.50
Step-by-step explanation:
First, set up an equation
18x=12x+75
Subtract 12x from both sides
6x=75
Divide both sides by 6
x=12.5

Answer:
The length of segment AC is 10 units ⇒ 1st answer
Step-by-step explanation:
Look to the attached figure
In circle A
∵ AB is a radius
∵ BC is a tangent to circle A at B
- The radius and the tangent are perpendicular to each other
at the point of contact
∴ AB ⊥ BC at point B
∴ m∠ABC = 90°
In ΔABC
∵ m∠B = 90°
∵ AB = 8 units
∵ BC = 6 units
- By using Pythagoras Theorem (Square the hypotenuse is
equal to the sum of the squares of the other two sides of
the triangle)
∵ (AC)² = (AB)² + (BC)²
∴ (AC)² = (8)² +(6)²
∴ (AC)² = 64 + 36
∴ (AC)² = 100
- Take √ for both sides
∴ AC = 10 units
The length of segment AC is 10 units

Answer:
-88
Step-by-step explanation:
If a=2, we can say that -
would be -4.
Secondly, if a=2 and b=-6 we can assume that 4ab would become -48.
Finally, if b=-6 we can say that -
would become -36.
Adding all of those up gives you -88, your answer.
