Distribute the two to each of the values in the parentheses.
-4 +6a-10= 1-1a
Then move like terms to the same side to simplify.
6a+1a=1+10+4
7a=15
a=15/7
Answer:
27.73 cm squared
Step-by-step explanation:
In order to find the shaded region, we need to find the areas of the circle and the rectangle and then subtract the circle area from the rectangle area.
The area of a rectangle is denoted by: A = lw, where l is the length and w is the width. Here, the length is l = 7 and the width is w = 8. Plug these in:
A = lw
A = 7 * 8 = 56 cm squared
The area of a circle is denoted by: A = πr², where r is the radius. Here, the radius is r = 3, so plug this in:
A = πr²
A = π * 3² = 9π ≈ 28.27 cm squared
Now subtract 28.27 from 56:
56 - 28.27 = 27.73
The answer is thus 27.73 cm squared.
Yes it can hold up to a little over 4 liters
Answer:
- 1, 1, - 3
Step-by-step explanation:
To obtain the value of f(1), we require the corresponding value of y from the graph when x = 1
From the graph
when x = 1 the value of y on the graph is - 1 ⇒ f(1) = - 1
Similarly
f(3) means what is the value of y corresponding to x = 3
From the graph when x = 3 then y = 1 ⇒ f(3) = 1
and f(- 1) = - 3
