Answer:
Step-by-step explanation:
<u>The line with points (1,2) and (-1,-8). Work out its equation.</u>
<u>The slope is:</u>
- m = (-8 - 2)/(-1 - 1) = -10/-2 = 5
<u>To find the y intercept, substitute x and y-xoordinates of point (1,2):</u>
- 2 = 5(1) + b
- b = 2 - 5
- b = -3
<u>The line is:</u>
<u>Point (x, 17), substitute y-coordinate and solve for x</u>
- 17 = 5x - 3
- 5x = 17 + 3
- 5x = 20
- x = 20/5
- x = 4
You are told that B=3g-7 and you are also told that B=17 so
3g-7=17 add 7 to both sides
3g=24 divide both sides by 3
g=8
So Gabriela is 8 years of age.
Answer:
Rule = 759375(1/15)^(n-1)
Where n represent the number of term
Step-by-step explanation:
a5= ar^4= 15
a6= ar^5= 1
ar^4=15... Equation 1
ar^5=1.... Equation 2
Dividing equation 2 by equation 1
r= 1/15
For the value of a
ar^5=1
a(1/15)^5= 1
a(1/759375)= 1
a= 759375
Rule = 759375(1/15)^(n-1)
Where n represent the number of term
