help on what
Step-by-step explanation:
40 garments need to be dry cleaned for the two companies to have the same cost.
<h3>
Linear equation</h3>
Linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let f(x) represent the cost for dry cleaning at Company 1. Hence using the points:
- (5, 115.25) and (15, 155.75)

Let g(x) represent the cost for dry cleaning at Company 2. Hence using the points:
- (5, 45.25) and (15, 105.75)

For the cost to be the same:
4.05x + 95= 6.05x + 15
x = 40
40 garments need to be dry cleaned for the two companies to have the same cost.

Answer:
hi!
So it gives you what f(x) equals AND what g(x) equals.
So, if you want F(x)+g(x), then just fill it in!
So it would be
-5x - 7 +6x - 4
-5x+5x-7+6x+5x-4
-7+11x-4
-7 + 7 +11x - 4+7
So, your answer would be 11x + 3
Hope i helped!
Answer:
50.28 sq. cm.
Step-by-step explanation:
A and B are centers of two circles of radii 8 cm and 1 cm such that AB =13 cm.
Now, angle ACB =90 degree where C is the center of another circle which touches the above two circles.
Now, ABC forms a right triangle where AB = 13 cm, AC = (r + 8) cm and BC = (1 + r) cm.
{Where r is the radius of the circle C.
Applying Pythagoras Theorem. AB² = AC² + BC²
⇒ 13² = (r + 8)² + (r + 1)²
⇒ 169 = r² + 16r + 64 + f² + 2r + 1
⇒ 2r² + 18r - 104 = 0
⇒ r² + 9r - 52 = 0
⇒ (r + 13)(r - 4) = 0
Hence, r = 4 {As the value of r can not be negative}
Therefore, the area of the circle C is π(4)² = 50.28 sq. cm. (Answer)
The largest number that 8c could be is -15
