Answer:
$30.80
Step-by-step explanation:
10% of $28 is 2.80
add 28+2.80=30.80
Answer:
x = 2/3
Step-by-step explanation:
cross multiply
-9(x-4) = 10(3x+1)
and then solve the equation
-9x + 36 = 30x + 10
36 = 39x + 10
26 = 39x
x = 2/3
Answer:
Qu.3 a = 70 degree.
Qu 4. a = 6 b= 4 c = 15 d =9
Step-by-step explanation:
Rules of parallelogram show that diagonal adjacent angles are equal
Then 110 = 110 and 110+110 = 220
Then as angles equal 360 degree we subtract.
a * 2 = 360-220 = 140 degree
Where there are two angles we divide by 2 to find one of them = a as both measures equal double;
a = 140/2 = 70 degree.
Qu 4. a = 6 b= 4 c = 15 d =9
without calculator we simplify
a= 3/4 x 8 = 1 x 8 - 1/4 = 6 = 3/4 +1/4 = 1 then 1 *8 = 8 then 8 -1/4 = 6 or go decimal 0.75 * 8 = 0.40 + 5.60 + total = 6
b = 2/6 x 12 = 1/6 x 12 (2) = 2 (2) = 4 = 1/6 *2 is the same as 2/6 we then *12
c = 3/2 x 10 = 1/2 x 10 (3) = 5 (3) = 15 = 1/2 *3 is the same as 3/2 we then *10
d = 3/12 x 36 = 1/4 x 36 = 9 = decimal 0.25 x 36 = 1.50 | + 7.5 = 9
B the gravitational waves sometimes seen on your television contain prices of the Big Bang or the "aftershock"
Using the vertical asymptote of the function, it is found that it is given by:
![f(x) = -1.5\frac{(x - 4)}{x - 2}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20-1.5%5Cfrac%7B%28x%20-%204%29%7D%7Bx%20-%202%7D)
<h3>What are the asymptotes of a function f(x)?</h3>
- The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.
- The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.
In this problem, the x-intercept of the graph is x=4, hence the numerator is a(x - 4).
The graph has one vertical asymptote at x=2, hence the denominator is x - 2.
Hence:
![f(x) = \frac{a(x - 4)}{x - 2}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7Ba%28x%20-%204%29%7D%7Bx%20-%202%7D)
The y-intercept of the graph is y=−3, hence:
![-3 = \frac{a(0 - 4)}{0 - 2}](https://tex.z-dn.net/?f=-3%20%3D%20%5Cfrac%7Ba%280%20-%204%29%7D%7B0%20-%202%7D)
![-4a = 6](https://tex.z-dn.net/?f=-4a%20%3D%206)
![a = -1.5](https://tex.z-dn.net/?f=a%20%3D%20-1.5)
Thus, the function is:
![f(x) = -1.5\frac{(x - 4)}{x - 2}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20-1.5%5Cfrac%7B%28x%20-%204%29%7D%7Bx%20-%202%7D)
