Solve for x. 3/4x + y = e Show work.

To solve for x you need to get it by itself
start by subtracting y
3/4x=e-y
then divide by 3/4 or multiply by 4/3
so, x=(4(e-y))/3
distribute
x=(4e-4y)/3 or x=4/3e-4/3y

a. With the picture missing, and 8 appearing in the choices, a can only assume that the spinner has 8 equal sectors.

b. P(Event)=n(Event)/n(Sample space)

c. P(number greater than 2)=n{3,4,5,6,7,8}/n{1,2,3,4,5,6,7,8}=6/8=3/4

2.

a. Sample Space: {2I, 3A, 2M, 2T, H, E, C, N}, n(S)=13

Event T:"selecting T" has a probability of P(T)=n(T)/n(S)=2/13
Event A: "selecting A" has a probability of P(A)=n(3)/n(S)=3/13

Events A and T are mutually exclusive, so P(A or T)=P(A)+P(t)=5/13

3.

a. Event W: white socks, n(W)=3

b. n(Sample space)=n(S)=n(3W, 4B, 2C)=9

c. P(W)=n(W)/n(S)=3/9=1/3

Answer:

Question 9) $y=\frac{-3}{2}x+2 \\\\$

Question 10) $y=-x-6\\$

Step-by-step explanation:

Well there are two methods of determining an equation of line

Method 1 (Using the slope-intercept form):

$y=mx+b$

This method is mostly used when the y-intercept also known as b is given and the slope also known as m is given

Method 2 (Using the point-slope form):

$y-y_1=m(x-x_1)\\$

This method is used when a point is given also known as (x1 , y1) and the slope is given which is denoted by m.

Since in Question 9 there is no y-intercept given only two points we will use the second method so here goes,

Q9)

Two points are (0 , 2) and (4 , -4) first step to find out the equation of line is to calculate the slope which is as follows:

$m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{-4-2}{4-0} \\\\m=\frac{-6}{4}\\\\m=-3/2 \\$

Now we have our slope which is m = -3/2 now since we have two points we can use any point in the point-slope form equation because both of these points lie on the line hence satisfying the desired equation that we need so we select the point (0 , 2) [YOU CAN TRY OUT FINDING THE EQUATION OF LINE BY USING THE OTHER POINT THE ANSWERS WOULD BE SAME]

so now we have the point (0 , 2) and value of m = -3/2

$y-y_1=m(x-x_1)\\y-2=\frac{-3}{2}(x-0)\\\\y-2=\frac{-3}{2}x\\\\y=\frac{-3}{2}x+2\\\\$
