Height of the triangle with AB as base = 2 – (–3) => 5

<span>Area = (1/2) * base * height => (1/2) * 8 * 5 ==> 20 sq. units. </span>

First, consider (0,2) and (8,2). The y-value is the same for both points. x ranges from 0 to 8, so the length of this horizontal side of the triangle is (8-0), or 8.

Again, this horiz. side has a y-value of 2.
The third point is (4,-3). Therefore the vertical distance from the horizontal line to the third point is 2 - (-3), or 5.

Thus, the "base" of the triangle is 8 and the "height" is 5.

The area is A = (bh)/2. Substitute the values 8 and 5. Simplify your result. Answer: 20 square units.

What’s the answer for a, and b, and how would you solve it?

xxTIMURxx [149]

Answer:

a) negative

b) -7/6

Step-by-step explanation:

The x value increased, but the y value decreased so the line goes down and has a negative slope

(y₁-y₂)/(x₁-x₂) is the slope where (x₁,y₁) and (x₂,y₂) are points on the line

(4-(-3))/(-1-5)=7/-6

1044 fans join a club in the first month after the first month nine new members are allowed to join each month how many members

laiz [17]

Answer:

Total number of members in month 34 is 1341 members.

Step-by-step explanation:

We have given,

Number of fans join a club in first month = 1044

And after the first month nine new members are allowed to join each month.

After first month , Let the number of club members in x months will be given as:

Number of members = 1044 + 9x

We need to find number of members in month 34.

So for first month we already had 1044 members, that mean for remaining 33 months we need to calculate members.

i.e total number of members in month 34 = 1044 + (33×9 ) , {Since x = 33 here}

OR total number of members in month 34 = 1044 + 297 = 1341 members
