From the equation, we have
To find the vertex and focus, we have to use the following formula
And
So, we have
Answer:
the answer is a) 100*
the angles it is bigger than is an acute angle (below 90)* and a right angle (exactly 90*) so the answer is anything above 90* and so it has to be 100*
The answer is 14 because they already give you x
Answer:
Well, first to plot the graph, you need to find the coordinates of the x and y variables. This you can find by the equation you have
y = -x + 7
when,
x =1 , y =6
x =2 , y =5
x = 3 , y =4
x = 4 , y =3
x =5 , y =2
x =6 , y =1
x =7 , y = 0
x =8 , y = -1
Now, plot these values in the graph. Cheers :)
Multiply 6x2 and you will get 12 and subtract that by the number 14 you see in the number and bring down the 4 and divide 24 by 6 and the quotient you will put next to the 4 and multiply 4 x 6 and you'll get 24 and subtract that by 24 and the remainder is zero
