Answer:
Step-by-step explanation:
You need to get the denominators the same. You could multiply 2/6 by 6 on the numerator and the denominator, but that's a little awkward. It's better to divide 18/36 by 6 on the top and bottom
18 / 6 = 3
36 /6 = 6
That's as far as you need go for this question. Don't be fooled by other questions that require you to go further.
3/6 - 2/6 = 1/6
Note the denominators remain the same.

3/5y + 9
3/5y + 15
9/5y + 9
9/5y + 15
Answer:
9/5y + 9
Step-by-step explanation:
You have to do the distributive property, which means you multiply everything that's outside the parenthesis with everything that's inside the parenthesis. If you do that, you get 9/5y + 9

Answer:
x = - 3 or x = 3x = 3 is removableStep-by-step explanation:
Given function is discontinuous when the denominator is zero:
x² - 9 = 0x² = 9x = √9x = 3 or x = - 3If you simplify the function:
f(x) = (x - 3) / (x² - 9) = (x - 3) / (x - 3)(x + 3) = 1 / (x + 3)Then the new function will have one of the discontinuity (x = 3) removed.
Discontinuity occurs at asymptotes
Find the vertical asymptotes
x²-9=0(x+3)(x-3)=0x=±3Simplify the function
x-3/(x+3)(x-3)1/x+3x=3 is removable

The table below shows the amount of flour and eggs you need for making different-sized batches of cookies using the same recipe.
Cups of flour Number of eggs
Batch A 3 2
Batch B 9 6
Batch C 12 8
Write an equation to describe the relationship between f, the cups of flour, and e, the number of eggs.
This table shows a proportional relationship with x and y find the constant proportionality (k). Using the value for k enter it in y=kx
Answer:
k=8
Step-by-step explanation:
(1st row)
24 = k x 3
24/3 = k
k = 8
(2nd row)
40 = k x 5
40/5 = k
k= 8
so, it proves that y=8x
k=8

Find the missing side of the triangle shown below, if the perimeter is 81.
The missing side of the triangle if the perimeter is equals to 81 is 28.8
Perimeter:Perimeter is the sum of the whole sides of a figure. The perimeter of the triangle above is the sum of the whole three sides.
Therefore,
let
the missing side = x
perimeter = 81
27.7 + 24.5 + x = 81
52.2 + x = 81
subtract 52.2 from both sides
52.2 - 52.2 + x = 81 - 52.2
x = 28.8

The height of two plants is in the ratio 7 : 9. The height if the taller plant is 26cm more than the height of the shorter plant. [3]
a) What is the height of taller plant?
b) What is the height of shorter plant?
c) What is their total length?
Answer:
see explanation
Step-by-step explanation:
Plants in ratio 7 : 9 = 7x : 9x ( where x is a multiplier )
Taller plant is 26 cm more than height of smaller, then
(a)
9x = 7x + 26 ( subtract 7x from both sides )
2x = 26 ( divide both sides by 2 )
x = 13
taller plant = 9x = 9 × 13 = 117 cm
(b)
shorter plant = 7x = 7 × 13 = 91 cm
(c)
total length = 117 + 91 = 208 cm
Answer:
a) 117 cm b) 91 cm c) 208 cm
Step-by-step explanation:
given smaller plant:taller plant = 7 : 9
let the height of smaller plant be x
then the height of taller plant will be x + 26
using this a equation can be formed:
9x = 7 ( x + 26 )
9x = 7x + 182
2x = 182
x = 91 cm ......this is the height of smaller plant
the height of taller plant will be:
x + 26 = 91 + 26 = 117 cm .............this is the height of taller plant
Now total length: 117 + 91 = 208 cm .....this is the total length.

12 + 7 = 19
Answer: 19
Answer:
19Basic fact:
two negatives make a positive
Step-by-step explanation:
x=-4
so replace 3x with x being -4
so it is

A recipe for bread calls for 4 cups of flour for every 1/3 cup of water. Using the same recipe, how much water will you need for 7 cups of flour?
Answer:
7/12 c
Step-by-step explanation:
4 / 1/3 = 7 / x
Cross multiply
1/3 * 7 = 4x
7/3 = 4x
7/3 divided by 4 = x
Multiply by reciprocal
7/3 * 1/4 = x
7/12
A recipe for bread calls for 4 cups of flour for every 1/3 cup of water. so we need 7/12 cups of water for 7 cups of flour.

The inverse of the logarithmic function f(x) = log0. 5x is f−1(x) = 0. 5x. What values of a, b, and c complete the table for the inverse function? x −2 −1 0 1 2 y 4 a b 0. 5 c a = b = c =.
The value of a, b and c can be calculated using the inverse function.
The calculated the value of a= 2, b=1 and c= -2.
Given:
The function is [tex]f(x)=\log_{0.5}x[/tex] and its inverse is [tex]f^{-1}(x)=0.5^x[/tex] .
What is an inverse function?The inverse function of a function is defined if [tex]f[/tex] is a function that undoes the operation of [tex]f[/tex]. The inverse of [tex]f[/tex] exists if and only if [tex]f[/tex] is bijective, and if it exists, is denoted by [tex]f^{-1}[/tex].Substitute the value of x= -1 in a given inverse function and calculate the value of a.
[tex]f^{-1}(x)=0.5^x\\ f^{-1}(-1)=0.5^{-1}\\ f^{-1}(-1)=2[/tex]
Substitute the value of x is 0 in given inverse function.
[tex]f^{-1}(x)=0.5^x\\ f^{-1}(0)=0.5^0\\ f^{-1}(0)=1[/tex]
Substitute the value of x is 2 in given inverse function.
[tex]f^{-1}(x)=0.5^x\\f^{-1}(2)=0.5^2\\f^{-1}(2)=-2[/tex]
Therefore, the value of a= 2, b=1 and c=-2.

Cash outflow=$800+$250+$150+$250+$60+$40=$1550
20% of cash inflow = $510 ($2050*0.2)
$2050-$1550=$500
