Step a is (2,7)/(8,13).

Step b is 1

Step c is y-7 = x-2

Step d is y = x +5

A) You would use the two points that are closest to the graphed line

(2,7) and (8,13)

B) Slope = change in Y over the change in X:

Slope = (13-7) / (8-2) = 6/6 = 1

Slope = 1

c) Point slope is written as y -y1 = m(x-x1) where m is the slope y1 is the first Y value and x1 is the first x value.

Equation is: y-7 = x-2

d) To rewrite y -7 = x-2 in slope intercept form, you need to isolate y.

To isolate Y add 7 to both sides:

y = x +5

grin007 [14]

Answer:

$33.14\°$

Step-by-step explanation:

Let

Y ----> field of vision that Yash's camera would need

we know that

Applying the law of sines

$\frac{sin(Y)}{25}=\frac{sin(41\°)}{30}$

Solve for sin(Y)

$sin(Y)=\frac{sin(41\°)}{30}(25)$

$Y=sin^{-1}[\frac{sin(41\°)}{30}(25)]$

$Y=33.14\°$

Melisande collected 14 bottles on Saturday and 9 bottles on Sunday for recycling. On Monday, she took all the bottles to the rec

Ann [662]

Answer:

Option B is correct that is amount she is getting per bottle is $0.15

Step-by-step explanation:

We have been given the information that melisande collected 14 bottles on saturday and 9 bottles on sunday

That means she has collected total of 23 bottles

Let us assume that the amount she is paid for recycling is $b

Since, she is left with $3.20 after the amount she gets for bottles we will get the equation below:

23b=3.20

Now, since she has to pay one time service fee equation will become

23b -0.25 =3.20

After simplification we will get

23b=3.20+0.25=3.45

b=3.45/23=.15

b=$0.15

Therefore, The amount she is getting per bottle is $0.15

If I have a 62% in a class, what percentage do I need to get on a 50% weighted test grade to have at least a 70% in the class?

Nastasia [14]

Answer:

78%

Step-by-step explanation:

70 = 0.50 (62) + 0.50 (x)

70 = 31 + 0.5x

39 = 0.5x

x = 78

You must get at least a 78% on the test to have at least 70% in the class.

If 60 is 75% of s value, what is that value

ohaa [14]

Let's write it down:
<span>"60 is 75% of s" means:

60=75%*s

75% is $\frac{75}{100}= \frac{3}{4}$ , (percent just means "out of 100" so we just divide it by 100) so we can also write:

60=</span><span> $\frac{3}{4}$ s

now, let's multiply both sides by 4:

240=3s

and divide by 3:
80=s

So we have the result that the original value, s, is 80!
