6 0

Answer:

y+7 = 1/7(x+3)

Step-by-step explanation:

Point slope form of a line is given by

y-y1 = m(x-x1)

where m is the slope and (x1,y1) is a point on the line

(y - -7) = 1/7(x - -3)

y+7 = 1/7(x+3)

What is the solution to the equation ?

Savatey [412]

Answer:

There is no solution of the system of equations.

Step-by-step explanation:

We are given two equations y = - 4 and y = 4 and are to find the solution to the equations.

Now, the straight line y = - 4 is parallel to the x-axis as the equation of straight lines that are parallel to the x-axis are given by y = c, where c is any constant value.

Again, the straight line y = 4 is parallel to the x-axis.

Therefore, y = - 4 and y = 4 two lines are parallel to each other and we know, parallel lines never intersect and hence there is no solution of the system of equations. (Answer)

2.24 Exit poll: Edison Research gathered exit poll results from several sources for the Wisconsin recall election of Scott Walke

iVinArrow [24]

Answer:

0.4929 = 49.29% probability that he voted in favor of Scott Walker

Step-by-step explanation:

Bayes Theorem:

Two events, A and B.

$P(B|A) = \frac{P(B)*P(A|B)}{P(A)}$

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

In this question:

Event A: Having a college degree.

Event B: Voting for Scott Walker.

They found that 57% of the respondents voted in favor of Scott Walker.

This means that $P(B) = 0.57$

Additionally, they estimated that of those who did vote in favor for Scott Walker, 33% had a college degree

This means that $P(A|B) = 0.33$

Probability of having a college degree.

33% of those who voted for Scott Walker(57%).

45% of those who voted against Scott Walker(100 - 57 = 43%). So

$P(A) = 0.33*0.57 + 0.45*0.43 = 0.3816$

What is the probability that he voted in favor of Scott Walker?

$P(B|A) = \frac{0.57*0.33}{0.3816} = 0.4929$

0.4929 = 49.29% probability that he voted in favor of Scott Walker

A rectangular garden has a total area of 48 square yards.Draw and label2 possiblerectangular garden with different side lengths

erastovalidia [21]

Answer:

see diagram

Step-by-step explanation:

A rectangle has the area that can be calculated using formula

$A=\text{length}\cdot \text{width}.$

1. Consider rectangle with length of 8 yards and width of 6 yard. Then

$A=6\cdot 8=48\ yd^2.$

2. Consider rectangle with length of 12 yards and width of 4 yard. Then

$A=12\cdot 4=48\ yd^2.$

These two rectangles are attached.

Use substitution to solve the system.<br> y=2x+11<br>3x+4y=−11

Komok [63]

Substitute 2x + 11 where you see y in the second equation and solve for x.
3x + 4(2x + 11) = -11
3x + 8x + 44 = -11
11x + 44 = -11
11x = -55
x = -5
Now, substitute -5 where you see x in the first equation and solve for y.
y = 2(-5) + 11
y = -10 + 11
y = 1
The answers are x = -5 and y = 1.
