Answer:

f(2)=6

Step-by-step explanation:

Replace all x's with 2:

f(2)=-2(2)+10

Now multiply by 2:

f(2)=-4+10

Simplify:

f(2)=6

Hope this helps!

The following table shows the distance from school as a function time
kykrilka [37]

Answer:

27,0 the distance away from the school​

Step-by-step explanation:

Apply the formula for equation of a straight line;

y=mx+c where c is the y intercept , and m is the gradient

From the graph, the slope is negative where speed decreases with increase in time

Find the gradient by applying the formula;

m=\frac{y_2-y_1}{x_2-x_1}

Taking y₁=24, y₂=20, x₁=9, x₂=12

Then;

m=\frac{20-24}{12-9} =\frac{-4}{3}

write the equation of the function as ;

y=mx+c, c=36( the y-intercept when x=0) hence the equation is;

y=mx+c\\\\y=\frac{-4}{3}x+36

To get x-intercept, substitute value of y with 0

y=mx+c\\\\\\y=-\frac{4}{3} +36\\\\\\0=-\frac{4}{3} x+36\\\\\frac{4}{3}x =36\\\\\\4x=36*3\\\\\\x=108/4=27

This means that the x-intercept is 27 ,and this means you will require 27 minutes to cover the whole distance to the school.

Step-by-step explanation:

angles on a straight line sum up to 180°

104+x+x+10=180

114+2x=180

2x=180-114

2x=66

x=33

Which equation represents the relationship between x and y shown in the table?
Hunter-Best [27]

Answer:

y=2x-3

Explanation:

which equation represents the relationship between x and y shown in the table?

x | y

2 | 1

4 | 5

6 | 9

8 | 13

take a look at the values in the table one more,

we find the gradient of the line to be

G=y2-y1/(x2-x1)

G=13-1/(8-2)

slope/gradient=12/6

m=2

from equation of a line graph, we know

y=mx+c

m=gradient

c=intercept

y=vertical axis

x=a point on the horizontal axis

y=2x+c

when x=6, y=9

9=2(6)+C

c=-3

Therefore the equation becomes

y=2x-3
