What phrase best describes a rhombus

1 answer:

8 0

B should be the answer but don't hold that to me. I say B because a rhombus only has two parallel sides which are the top and bottom lines.

Write an equation of the line that passes through (2 , 0) and is perpendicular to the line y=-1/7x-3

aleksley [76]

Answer:

y = 7x - 14

Step-by-step explanation:

If the given line has slope -1/7, then any perpendicular line has the slope which is the negative reciprocal of -1/7. That is +7.

Apply the slope-intercept formula for the equation of a straight line, using 0 for y, 2 for x and searching for the y-intercept value b:

0 = 7(2) + b. Then b = -14, and the desired equation is y = 7x - 14.

Answer:

A) $y+7=-3(x-4)$

Step-by-step explanation:

Hi there!

The given equations are written in point-slope form: $y-y_1=m(x-x_1)$ where <em>m</em> is the slope of the line and $(x_1,y_1)$ is a point that falls on the line

Notice how the line is travelling infinitely down as x increases. This means that the slope is negative.

Therefore, the equation of the line is either A or B.

Now, let's look at A:

$y+7=-3(x-4)$

This equation suggests that the point (4,-7) falls on the line, which it does.

Therefore, the equation of the graph is $y+7=-3(x-4)$ .

I hope this helps!

A video game randomly chooses your car color and type. The probability of getting a red car is 0.20, and the probability of gett

pishuonlain [190]

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Event A: You get a red car

and

$P(A)=0.20$

Similarly,

Event B: You get a convertible

and

$P(B)=0.40$

So, if A and B are independent , then they must satisfy,

$P(A).P(B)=P(A\cap B)$

So,

$P(A\cap B)=0.4\times 0.2=0.08$

Hence, Option 'D' is correct, which states that the probability of getting a red convertible is 0.08.
