Area of triangle with following verticies (0,-9), (3,-9), and (0,-2)

Mathematics

Answer:

Area = 21/2 = 10.5 area units

Step-by-step explanation:

Two of the points are on the same line (the y-axis) as they both have x-coordinates of 0. This can thus be the base of your triangle.

Two more are on the same line (y= -9) as they both have the same y-coordinate of -9. This can be the height of your triangle.

So you have a base which is between -2 and -9 (7 units) and a height which is between 0 and 3 (3 units) so now just use the equation for area of a triangle A=0.5*b*h

Graph the line whose y-intercept is - 9 and whose x-intercept is 5.
Nostrana [21]

Answer:

y=1.8x-9

Step-by-step explanation:

if they are intercepts so the x/y will be zero, so in y intetceot the x is zero, and in the x itercept the y is zero.

0,-9

5,0

we calculate the slooe / rise

-9-0/0-5 = 1.8

we then use this formula

y-y1=rise(x-x1)

y-0=1.8(x-5)

y=1.8x-9

Does the equation y = 99x show a proportional relationship between x and​ y?
Naily [24]
Yes because it shows that y is proprtional equal to 99 times x. so whenever you need to work out y, you get x and times it by 99.

Complete the statements about the series
AleksAgata [21]

Answer:

Ok, first in our series we can see two numbers in the Sigma, one bellow 0, and other above, 4.

This means that the value of k will go from 0 to 4, then all the numbers in the sum are:

(-1/2)^0 + (-1/2)^1 + (-1/2)^2 + (-1/2)^3 + (-1/2)^4

So we have 5 terms in our series.

b) to see the sign in each term, we must solve the powers, remember that:

(-1)^n is -1 if n is odd, and is equal to 1 if n is even, so we have:

(-1/2)^0 + (-1/2)^1 + (-1/2)^2 + (-1/2)^3 + (-1/2)^4

= 1 -1/2 + 1/4 - 1/8 + 1/16.

So the sign in each term of the series alternates.
