Answer:
10
Step-by-step explanation:
f(x) = 3x - 2
Let x=4
f(4) = 3*4 - 2
=12-2
=10
Answer:
Equation: 154 = 158n - 132 n = 11/6
Step-by-step explanation:
Let's start by converting this into an equation. Some keywords to look for are "is" which means an equal sign (=), "product" which is multiplication (*), and "decreased" which means a minus sign (-):
So this is our equation: 154 = 158n - 132
Now we have to solve for n:
First, we add 132 to both sides to isolate the n more:
286 = 158n
Then to completely isolate the n, we divide both sides by 158
286
------ = n
156
<u>n = 11/6, final answer.</u>
Answer:
y=a-4 divided 3-a and a cut so remember 4divided3 so, y= 1.33

Answers and Step-by-step explanation:
Question 8:
Since angle BCD is opposite angle DAB, this means that they are similar angles as the shape is a parallelogram, and so BCD is 115 degrees, or answer D
Question 3:
We can use process of elimination on this question - The first choice is all squares are rhombuses, which is true. The second question is all rectangles are squares, which is not true, therefore the answer is B
Question 4:
m angle 2 is equal to 106, as it is similar to question 8, and angle 3 is equal to 360 (the total degrees of the shape) - 106 - 106, then divided by 2 and divided by 2 again.
This will equal to angle 3 being 37 degrees, and the answer will be C
Question 5:
We can draw a rectangle from this graph. We can also tell that, in theory, the diagonals are the same, that rules out answer B, and also 5x-5 = x+11
We can then find out x.
+5 on both sides
5x = x+16
-x on both sides
4x = 16
x = 4.
Therefore, each of the sides will be 4+11 = 15, and the answer being C
A complement (
) is described by {x|x ∈ U and x is an even positive integer}
