Answer:

y = 5/6x + -8

Step-by-step explanation:

you first need to find the gradient using the formula m = (y2 - y1)/(x2 - x1)

the gradient would be 5/6.

the slope intercept form equation is y = mx + c. so by taking one of the points, 2 = 5/6(4) + c

12 = 5(4) + c

12 = 20 + c

c = 12 - 20

c = -8

hence, y = 5/4x + -8

1) PART A : determine the domain and range of the function in the graph.

anzhelika [568]

1) Domain: x is greater than -2 and greater than or equal to 5
Range: y is greater than -1 and less than or equal to 3

2) No the function is not one to one because one to one functions can’t have multiple points on a function with the same y value.

Answer the value of x

GalinKa [24]

Answer:

Step-by-step explanation:

(8-2)*180=1080 degrees

114+66+94+259+94+67+254+97+x=1080

1045+x=1080

1080-1045=x

x=35

What value of X is always

valentina_108 [34]

Answer:

Answer B

Step-by-step explanation:

Because (IQR) by 1.5 (a constant used to discern outliers). Add 1.5 x (IQR) to the third quartile. Any number greater than this is a suspected outlier. Subtract 1.5 x (IQR) from the first quartile.

A linear function has the same y-PLEASE PLEASE HELP!!!!intercept as x+2y=10 and it’s graph contains the point (9,7) find the slo

Anastasy [175]

Answer:

I think it is 2/9 or 0.22

Step-by-step explanation:

You know they have the same y intercept, so first you should find the y intercept of the givern equation.

x+2y = 10

2y = -x + 10 [subtract x]

y = -.5x + 5 [divide by 2]

Now you have the equation in graph form, and know the y intercept is 5.

If the unknown function has the same y intercept, you know it contains the point (0,5), and it is given that it includes the point (9,7)

now that you have two points, you can use slope formula.

(y2 - y1)/(x2-x1)

(change in y)/(change in x)

so,

(7-5)/(9-0) = 2/9 = 0.2

someone please correct me if i'm wrong:)
