Find the slope between the points. (4,-2) and (8,5)

1 answer:

3 0

Slope = m

Equation to find slope is:

m = (y2 - y1) / (x2 - x1)

2 points:
(4,-2) 4 = x1 and -2 = y1
(8,5) 8 = x2 and 5 = y2

So...

m = (y2 - y1) / (x2 - x1)

m = (5 - (-2)) / (8 - 4)

m = 7 / 4 or 1.75

Therefore, the slope of the line is 7/4 OR 1.75.

Write a function rule for the table х f(x) 0 3 1 4 2 5 3 6

ki77a [65]

Answer:

f(x) = x +3

Step-by-step explanation:

The first differences for adjacent x-values are all 1, so this is a linear function. Because those differences are all 1, it is a linear function with a slope of 1. We observe that f(0) = 3, so that is the y-intercept.

The slope-intercept form of a linear function is ...

y = mx + b . . . . . where m is the slope (1) and b is the y-intercept (3).

A suitable function rule is ...

f(x) = x +3

PLEASE HELP GUYS! The math club is order tee shirts for each member. The tee shirts cost $12.50 each plus a one - time set - up

ser-zykov [4K]

So ($25)

find out how much 126 t-shirts will cost including the $25 set up fee.
so in calculator its (12.50 × 126) + 25. This gives you 1600.
Now you know the answer, you work your way backwards.

y = x + $25

I THINK THIS IS RIGHT IF ITS NOT PLEASE TELL ME

A triangle has height 4 ft and area 32 ft2. What is the lenght of the base?

Blizzard [7]

$A=32ft^2 \\\\ A=\frac{b*h}{2} \\\\ \frac{b*4}{2}=32 \\\\ b=\frac{2*32}{4} \\\\ b=2*8 \\\\ \boxed{b=16ft}$

Solve the rational equation x divided by 6 equals x squared divided by quantity x minus 1 end quantity, and check for extraneous

pychu [463]

Answer:

$x = 0$ and $x = \textrm{negative one fifth}$

Step-by-step explanation:

Given:

The rational equation to solve is given as:

$\frac{x}{6}=\frac{x^2}{x-1}
$

We use the cross multiplication rule and multiply the numerators one side with the denominators of the other side. Therefore,

$x\times (x-1)=6\times x^2\\x^2-x=6x^2\\\textrm{Bringing all variables to the right side, we get:}\\6x^2-x^2+x=0\\5x^2+x=0\\x(5x+1)=0\\x=0\ or\ 5x+1=0\\x=0\ or\ x=-\frac{1}{5}
$

Now, for $x=0$ , the rational equation is equal to 0. So, $x=0$ is a solution.

Also, $x=-\frac{1}{5}$ is also a solution as the equation's denominator is defined at that point.

So, no extraneous solution.
