Step-by-step explanation:

remember that area =1/2 * b * h so to find base, you can make it the subject of formula i.e

b =area *h/2

or in the caseof h you can do

Two Aps have the same first and last terms .The first Ap has 21 terms with a common difference of nine how many terms has the ot

Pani-rosa [81]

Answer:

46 terms

Step-by-step explanation:

a₁=b, a₂₁= bₙ, d₁=9, d₂=4

n=?

---------------

a₂₁= a₁+20d₁= a₁+20*9= a₁+180

bₙ= b₁+(n-1)d₂= a₁+4(n-1)

a₁+4(n-1)=a₁+180

4(n-1)=180

n-1= 180/4

n-1= 45

n=46

A linear function has the same y-PLEASE PLEASE HELP!!!!intercept as x+2y=10 and it’s graph contains the point (9,7) find the slo

Anastasy [175]

Answer:

I think it is 2/9 or 0.22

Step-by-step explanation:

You know they have the same y intercept, so first you should find the y intercept of the givern equation.

x+2y = 10

2y = -x + 10 [subtract x]

y = -.5x + 5 [divide by 2]

Now you have the equation in graph form, and know the y intercept is 5.

If the unknown function has the same y intercept, you know it contains the point (0,5), and it is given that it includes the point (9,7)

now that you have two points, you can use slope formula.

(y2 - y1)/(x2-x1)

(change in y)/(change in x)

so,

(7-5)/(9-0) = 2/9 = 0.2

someone please correct me if i'm wrong:)
