Answer: A, -6

Step-by-step explanation: If it is the problem I think it is there should be a chart with the first column labeled x that includes -2, -1, 0, 1, and 2. The second column should be labeled y and includes 8, 2, -4, -10, and -16. You use the slope formula the m=rise/run which is also y2-y1/x2-x1=slope. So now you substitute y2 as 2, y1 as 8, x2 as -1, and x1 as -2. Now you do 2-8/-1- -2, which becomes 2+-8/-1+2. When you add 2 and -8 you get -6 and when you add -1 and 2 you get 1. Now we put them together to get -6/1, which equals -6, as our slope.

7. Which of the following can be determined from the graph below?

tatyana61 [14]

Answer:

The ordered pair (6,25) is a solution to both

$y=-\frac{5}{2}x+40$ and $y=\frac{5}{3}x+15$

Step-by-step explanation:

Part 7)

step 1

Find the equation of the line with positive slope

take the points (0,15) and (9,30)

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the given values

$m=\frac{30-15}{9-0}$

$m=\frac{15}{9}$

simplify

$m=\frac{5}{3}$

Find the equation of the line in slope intercept form

$y=mx+b$

we have

$m=\frac{5}{3}$

$b=15$

substitute

$y=\frac{5}{3}x+15$

step 2

Find the equation of the line with negative slope

take the points (0,40) and (8,20)

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the given values

$m=\frac{20-40}{8-0}$

$m=-\frac{20}{8}$

simplify

$m=-\frac{5}{2}$

Find the equation of the line in slope intercept form

$y=mx+b$

we have

$m=-\frac{5}{2}$

$b=40$

substitute

$y=-\frac{5}{2}x+40$

step 3

Find the solution of the system

we know that

The solution of the system of equations is the intersection point both graphs

The intersection point is (6,25) ----> see the graph

therefore

The ordered pair (6,25) is a solution to both $y=-\frac{5}{2}x+40$ and

$y=\frac{5}{3}x+15$

Find the exact value of sec theta if csc theta = -4/3 and the terminal side of theta lies in quadrant III

GREYUIT [131]

Answer:

-4 sqrt(7)/7

Step-by-step explanation:

csc theta = -4/3

csc theta = hypotenuse / opposite side

hypotenuse = 4

opposite = 3

Using the pythagorean theorem

a^2 + b^2 = c^2

3^2 + b^2 = 4^2

9+b^2 = 16

b^2 = 16-9

b^2 = 7

Taking the square root

sqrt(b^2) = sqrt(7)

b = sqrt(7)

We are in the third quadrant so only tan and cot are positive

that means the x and y values are "negative" so a = -3 and b = - sqrt(7)

sec theta = hypotenuse / adjacent

= 4/ - sqrt(7)

rationalizing

-4 sqrt(7)/ sqrt(7)* sqrt(7)

= -4 sqrt(7)/7

Need help with question 1 and 2 PLEASEEEE

aksik [14]

Answer:

P, M, N and C are coplanar, because they are on the same plane.

Noncollinear, because they are not on the same line.

Hope this helps :)

There are two major tests of readiness for college, the act and the sat. act scores are reported on a scale from 1 to 36. the di

ch4aika [34]

Standardized z score for the act result = (30 - 21.5) / 5.4 = 1.574

so for the sat ressult we have 1.574 = (X - 1498) / 316

X = 316 * 1.574 + 1498 = 1995 answer
