Answer:
i can only do 2 and 3 sorry
2. a
3.d
Step-by-step explanation:
Answer:
1% of 4000 + 4% of B = 2% of (4000 + B)
40 + 0.04*B = 0.02( 4000 + B)
40 + 0.04* B = 80 + 0.02*B
40 + 0.04*B - 80 - 0.02B = 0
0.02*B - 40 = 0
0.02*B = 40
2B = 4000
B = 2000
Step-by-step explanation:
Answer:
≈ 56°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin ? =
=
, then
? =

<u>ANSWER: </u>
The slope of the given equation is -2 and a point on the given line is (-1, 3)
<u>SOLUTION:</u>
Given, linear equation in two variables is y – 3 = -2(x + 1) ----- eqn (1)
We need to find the slope of the given equation and a point through which the given line passes.
Given equation is in the form of point slope form .i.e
--- eqn 2
where,"m" is the slope of the line
is point on that line.
Now, by comparing (1) and (2)
m = -2


so, the slope of the given equation is -2 and a point on the given line is (-1, 3)
Answer:
2. y=9x
3. 180*9 = 1620
Step-by-step explanation:
2. y = mx+b, so find the slop efirst
lacampanella avatar
so take the first two points you got
lacampanella avatar
(2,18) and (5,45),
lacampanella avatar
(45-18)/(5-2) = 9
lacampanella avatar
then use (2,18)
lacampanella avatar
18= 9*2+b
lacampanella avatar
so b=0
3. y = 9x
x= 180. y = 9*180 = 1620
