Just find the y intercept for both lines and calculate the change in y with respect to the x axis, aka slope. You can write an equation from any line by doing what I just said. The y-intercept is the y value where the function intercepts the y-axis.

Red Line:
Y-intercept = 2
Slope = 1/1

Blue Line:
Y-intercept = 4
Slope = -1/2

And you should know the equation, atleast I hope you do.
y = mx + b
m being the slope
b being the y-intercept

You now got:
y = x + 2
and
y = -(1/2)x + 4

Make them equal to each other since they are both equal to y. Solve for x and then solve for the actual y value. I don’t want to do everything for you, since you wouldn’t really learn anything

PLEASE HELP!!!! 25 POINTS!!!!
Andrei [34K]

Answer:

0.9562

Step-by-step explanation:

Binomial probability is mathematically expressed as:

P(X=x)={n\choose x}p^x(1-p)^{n-x}

Given that p=0.18, n=5 ,  is calculated as:

P(X\leq 2)=P(0)+P(1)+P(2)\\\\={5\choose 0}0.18^0(1-0.18)^5+{5\choose 1}0.18^1(1-0.18)^4+{5\choose 2}0.18^2(1-0.18)^3\\\\=0.3707+0.4069+0.1786\\\\=0.9562

Hence, the probability of no more than 2 successes in 5 trials is 0.9562

Shelly has $175 to shop for jeans and sweaters. Each pair of jeans costs $25 and each
Ksju [112]

Answer:

3 jeans and 5 sweaters

Step-by-step explanation:

This is a solid guess

However, this is a straight forward question.

175 she has to spend all of it.

To make it an even number you minus 25.

Than you have 150, minus another 50.

You have 5 more clothes to buy, and $100 left.

You use the rest to buy sweaters, therefore spending all the money and getting 8 clothing.

Can someone please help me with these math problems ASAP?!<br> Thanks in advance! ;)
Mamont248 [21]

Answer:

11) Here given Function,

f(x) = \sqrt{2x-11}

And, g(x) = -|0.1|x+5

For f(x) = g(x)

\sqrt{2x-11}=-|0.1|x+5

2x-11=(-|0.1|x+5)^2

2x-11=0.01x^2 - 10|0.1|x+25

2x=0.01x^2 - 10|0.1|x+25+11

2x=0.01x^2 - 10|0.1|x+36

0.01x^2 - 10|0.1|x - 2x+36=0

When we solve this equation,

We found,

 x = 12.5227 ≈ 12.53

Thus, the required solution is, x = 12.53

12) Here the height of rocket A in x second,

f(x) = -16x^2+74x+9

And, The height gain by the rocket B in x seconds,

g(x) = -16x^2+82x

If at x seconds both A and B gain the same height,

That is, f(x) = g(x)

⇒ -16x^2+74x+9= -16x^2+82x

⇒74x + 9 = 82x

⇒ 82x - 74x = 9

⇒ 8x = 9

⇒ x = 1.125 ≈ 1.13

Thus, the required solution is x = 1.13 seconds (approx)
