Here's a graph of a linear function.
Write the
equation that describes that function.
Express it in slope-intercept form.

Answers

Answer:

y = 1/2x + 3

Step-by-step explanation:

As per graph, using the points (-6, 0) and (0, 3) we determine that:

the y-intercept is 3 and the slope is m = (3-0)/(0 - (-6)) =  /3/6 = 1/2

So the equation is:

y = mx + by = 1/2x + 3

please help!​

Answers

Answer:

Rate Of Change= 7

Step-by-step explanation:

all you have to do is see the difference, imma make a table here first

x       y

1       10

3      24

6      45

11      80

15    108

from 10 to 24 you add 14

from 1 to 3 you add 2

so y/x

14/ 2 = 7

check:

from 24 to 45 you add 21

from 3 to 6 you add 3

so y/x

21/3 = 7

From y/x your final answer will always be 7.

So the rate of change will be 7.

The range of values for the third side is that;

x < 91

Step-by-step explanation:

For us to have a triangle formed, the length of the third side is smaller than the sum of the length of the two other sides

Mathematically;

Let us call the third side x

x < 52 + 39

Please help fast Prefer A Expert or Above to Help Me out it’s the bottom one!

Answers

Answer: 45

The value is approximate.

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

Explanation:

Focus on the upper triangle.

Label the unknown horizontal side as y

Use the pythagorean theorem to solve for y

a^2+b^2 = c^2

10^2 + y^2 = 26^2

100+y^2 = 676

y^2 = 676-100

y^2 = 576

y = sqrt(576)

y = 24

-----------

Now move to the bottom triangle

With respect to the reference angle, the side y = 24 is opposite this. The hypotenuse is unknown.

Use the sine rule to connect the two and solve for x

sin(angle) = opposite/hypotenuse

sin(32) = y/x

sin(32) = 24/x

x*sin(32) = 24

x = 24/sin(32)

x = 45.2899179551967 which is approximate

x = 45 rounding to the nearest whole number

Side x is approximately 45 cm long.

Note: make sure your calculator is in degree mode.
