You earn $250 per month from your part-time job. You are in a kayaking club that costs $20 per month, and you save at least $100

Olegator [25]

Answer:

Amounts in the intervall $130 \leq c \leq 230$

Step-by-step explanation:

We will take the variables c and s, where

c = amount to spend that month

s = savings of the month.

Since each month we save at least 100, we know that

$0 \leq s \leq 100$

Moreover, we earn $250 per month and we spend $20 in a kayaking club, which tells us that

$250=20+s+c$

and so

$230-s=c$

By multiplying by -1, the first inequality also tells us that

$-100 \leq -s \leq 0$

Consequently by adding 230 to the inequality, we get that

$230-100 \leq 230-s \leq 230\\\\\Rightarrow 130\leq c \leq 230$

Help me please this was due yesturday

stepan [7]

Step-by-step explanation:

Slope intercept form is

$y = mx + b$

where m is the slope( average rate of change) and b is the

y intercept( the y value when x is zero).

When x=0, y is 2. This means b=2

Slope is change in y value/ change in x value. Another obvious arbitrary point we are given is (-8,0).

So let use the formula we given.

So our slope is 1/4 so our equation is

1/4x+2

Please help meeeeeeee pt 4

liraira [26]

Answer:

The answer is

$2 {x}^{2} + 3x - 1 = 0$

Why? Below I explain

Step-by-step explanation:

That formula has three variables a, b and c.

So, a = 2, b = 3 and c = -1

Because the formula is written like

$\frac{ - b + - \sqrt{ {b}^{2} - 4 \times a \times c} }{2 \times a}$

While taking a ride in a hot-air balloon in Napa Valley, Francisco wonders how high he is. To find out, he chooses a landmark th

mihalych1998 [28]

The solution would be like this for this specific problem:

sin 54 degrees = Height/718.0624

Height = (sin 54 degrees)(718.0624) = 580.9 ft

So the height of the balloon is 580.9 ft. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.
