Answer: The furry pet store has 8 puppies in it.
Answer:
A=4 I think
Step-by-step explanation:
I=a+(n-1)d
25=a+(8-1)3
25=a+21
25-21=a+21-21
4=a
Answer:
y = -2/7x - 32/7
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
The slope is -2/7
y = -2/7 x+b
We know a point on the line is (5,-6)
Substitute this into the equation
-6 = -2/7(5) +b
-6 = -10/7+b
Add 10/7 to each side
-6 +10/7 = b
-42/7 + 10/7 = b
-32/7 = b
y = -2/7x -32/7
Slope
m = (y2-y1)/(x2-x1)
m = (10 - 7)/(2 --1)
m = 3/3
m = 1
To find the equation
y = mx + b
m is slope
y = 1x + b
plug in one of the equations to solve for b
10 = 1(2) + b
10 = 2 + b
subtract 2 from both sides
8 = b
The equation is
y = 1x + 8
or you can write it as
y = x + 8
Hope this helps
Answer:
In triangle ABC and triangle ADE
angle A = angle A (common)
anhle ABC = angle ADE
By AA , triangle ABC similar to triangle ADE
Thus
AB/AD = BC/DE
10/(10+x) = 6/10
60 + 6x = 100
6x = 40
x = 6.67
