I think the answer would be x=-7
y= 4x-1
y= 3x+6
y= 1x-1+6
y= 1x-7
x=-7

Y = 4x - 1
y = 3x + 6
=====
4x - 1 = 3x + 6
4x - 3x = 6 + 1
x = 7

y=4x - 1
y=4 x 7 - 1 = 27

x=5
y=27

Answer: $1267.18yd^2$

Step-by-step explanation:

$Formula: \pi r(r+\sqrt{h^2+r^2} )$

We need;

$\pi = 3.14\\r=?\\h=18yd$

We don't have the radius, but we do have the diameter. A diameter is twice the radius. Therefore, we can divide the diameter by 2 in order to obtain the radius.

$\frac{d}{2}= \frac{24}{2}=12yd$

Now plug this info into the formula.

$(3.14)(12yd)[(12yd)+\sqrt{(18yd)^2+(12yd)^2} ]$

Let's solve the square root first.

$(3.14)(12yd)[(12yd)+\sqrt{324yd^2+144yd^2} ]$

$(3.14)(12yd)[(12yd)+\sqrt{468yd^2} ]$

$(3.14)(12yd)[(12yd)+\sqrt{468yd^2} ]\\(3.14)(12yd)(12yd+21.63yd)$

Now solve the sum

$(3.14)(12yd)(33.63yd)\\$

Multiply

$1267.18yd^2$

In a game of chance, the probability of winning a $50 is 40% and the probability of losing a $50 prize is 60%. what is the expec

melamori03 [73]

To calculate expected value,
We can add up the probability of all possible events.
The 2 possible events are either winning $50 or losing the prize, which is $ - 50
Expected value =
50 x 40 % + (-50) x 60%
= $-10
So the answer is $-10

Answer:

y=4x-2

Step-by-step explanation:

if slope is 4, gradient is 4 so y=4x +c

given y intercept of -2,, y=4x -2

c=-2
