Answer:
Larger angle: 104 degrees
Smaller angle: 76 degrees
Step-by-step explanation:
(9x+5) + (6x+10) = 180
x = 11
Answer:
y = -6/5
Step-by-step explanation:
Remove parentheses
2y - 2 - 7y = 4
group like terms
2y - 7y - 2 = 4
add similar elements
-5y - 2 = 4
add 2 to both sides
-5y - 2 + 2 = 4 + 2
simplify
-5y = 6
divide both sides by -5
-5y ÷ -5 and 6 ÷ -5
simplify
y = -6/5
Answer:
a) x=0, x=1
b)x=0, x=4/3
Step-by-step explanation:
I didnt use the graph, just used algebra. For part a, you can find the answers using the graph by looking at the value of x when y = whatever value they give.
A)
3x²-3x+2=2
3x²-3x+0
x(3x-3)=0
For the product of two things to equal zero, one of them has to be zero. For example, if ab=0, then either a or b (or both) are zero.
Therefore..
x=0
or 3x-3=0, ∴x=1
b)
3x²-3x-1 = x-1
3x²-4x=0
x(3x-4)=0
∴x=0, x=4/3
Answer:
n - 6
Step-by-step explanation:
Firsly, break the bracket and you will get:
-2(n+3)+3n
= -2 * n + 3 * (-2) + 3n
= -2n + (-6) + 3n
= -2n + 3n - 6
= n - 6
Hope this helped :3
