Answer:
2 solutions:
x=5 and y=7
x=-1 and y=-5
Step-by-step explanation:
y=2x-3
y=x^2-2x-8
y=y so:
2x-3=x^2-2x-8
simplifying to:
x^2-4x-5=0
factoring to:
(x-5)(x+1)=0
x=5 or x=-1
if x=5 then y=2(5)-3=7
if x=-1 then y=2(-1)-3=-5
I think the answer is 6cm, 8cm, 10cm
<h3>Answer</h3>
B 5/8
<h3>Explanation</h3>
P(event)= 1/8 (the possibility that Jack rolls a 3) + 4/8 (the possibility that Jack rolls an even number such as 2,4,6,8) = 5/8
Answer:
40⁰
Step-by-step explanation:
<em><u>Main</u></em><em><u> </u></em><em><u>principles</u></em><em><u>:</u></em>
1.Alternate angles equal
2.Vertically opposite angles are equal
If angle 2 is 40⁰, then using the second principle,angle 3 is also 40⁰
Then, using the first principle,(alternate angles/angles that form any variation of "z"), angle 6 is also 40⁰.
There are other ways to do this like using co-interior angles, straight angles and other methods, these are the easiest to understand
