Answer:

y=4/3x+4

Step-by-step explanation:

Finding two points on the graph [I chose (-3,0) & (0,4)] subtract 4 (the second y) and 0 (the first y) to get 4. Then subtract 0 (the second x) and -3 (the first x) which will give you 3. The slope is 4/3. Then you find where the line meets the y-axis, which in this case is 4. Finally, write it in slope-intercept form: y=4/3x+4

Answer:

4/3

Step-by-step explanation:

y=mx+b

and B is y-intercept

m is the slop which is (y2-y1)/(x2-x1)

so m= (4-0)/(0+3)=4/3 that is the slop

Solve for the exact value of x.

forsale [732]

A² + b² = c²
5² + 8² = x²
x² = 25 + 64
x² = 89
x = √89
x = 9.43

Find P on AB that is 2/3 of the distance from A(-3,-5) to B(9,4).

Ludmilka [50]

A line segment can be divided into ratios.

<em>The coordinate of P on line segment AB is (5,1)</em>

Given

$A = (-3,-5)$

$B = (9,4)$

The position of P from A to B is:

$P_A = \frac 23$

So, from P to B would be:

$P_B =1 - \frac 23$

$P_B = \frac 13$

So, the ratio is:

$m : n = \frac 23 : \frac 13$

Simplify

$m : n = 2 :1$

<u>The coordinate of point P is:</u>

$P = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})$

So, we have:

$P = (\frac{2 \times 9 + 1 \times -3}{2 + 1},\frac{2 \times 4 + 1 \times -5}{2 + 1})$

$P = (\frac{15}{3},\frac{3}{3})$

$P = (5,1)$

<em>Hence, the coordinate of P is (5,1)</em>

If f(x) = -7x + 1 and g(x) = Square root of x-5,<br> what is (fºg)(41)?

Ghella [55]

This is similar to the other question you posted. Follow the same steps as before.

First find g(41).

g(41) = sqrt{x - 5}

g(41) = sqrt{41 - 5}

g(41) = sqrt{36}

g(41) = 6

We now find f(6).

f(6) = -7(6) + 1

f(6) = -42 + 1

f(6) = -41

Answer:

(fºg)(41) = -41
