Answer:

Step-by-step explanation:

what we know=

x is the independent variable and y is the dependent variable.

our co-ordinates can be expressed in the form of (x value, y value).

so... we only need two points for this so let's just list two points so it goes faster

A(-7,5)

B(-1,65)

alright, now we have two points. we're trying to find the rate of change, which in other words, is the slope.

m=(y-y1)/(x-x1) <-- plug in our points.

m=(65-5)/(-1-(-7)

m=60/(-1+7)

m=60/6

m=10

therefore the rate of change aka the slope of this table of values is 10.

Answer: Choice B

{(0,0), (1,2), (2,4), (3,4)}

===============================================

Explanation:

A function is only possible if each x input leads to exactly one y output. For choice A, we have x = 1 lead to y = 3 and y = 5 at the same time, which is what the points (1,3) and (1,5) are saying. Therefore, choice A is not a function.

Choice C is also ruled out because x = 2 repeats itself as well. In this case, (2,3) and (2,4) means that the input x = 2 leads to the two outputs y = 3 and y = 4.

Choice D can be eliminated also for two reasons: x = 0 shows up twice, so does x = 2.

Only choice B has each x value listed one time only. So that means each input leads to exactly one output.

If you graph choice A, C or D, you'll find they fail the vertical line test. The vertical line test is where you test if you can draw a vertical line through more than one point on the graph. If you can draw a vertical line through more than one point on the graph, then the relation fails to be a function.

A bag contains white matarles and red marables,126 in total.The number of whit marables is 6 more than 5 than 5 times the number
denis-greek [22]

Answer:106

Step-by-step explanation:

Let number of white marbles be w

Let number of red marbles be r

w+r = 126---------1

w = 6 +5r-----------2

Put eqn 2 in eqn 1

6+ 5r + r = 126

6 + 6r = 126

6r = 120

r = 20

w = 6 +5r =6+100

= 106

If one zero of the following polynomial 8x^2-13x-4k is the reciprocal of the other, then find k
Lana71 [14]

Answer:

Step-by-step explanation:

hello :

if x1 and x2 this zero for ax²+bx+c  you have : x1 = 1 /x2  means :x1 × x2 =1

but : x1 × x2 = c /a

in this exercice : a =8  and b = -13  and c = - 4k

so : c/a =-4k/8

so : -4k/8 = 1

-4k = 8        k = 8/-4      k = -2  

this polynomial is : 8x²-13x +8
