I might be wrong but don’t you need two equations to do the elimination process?
Answer:
£124
Step-by-step explanation:
first of all, you're meant to add all the figures given on the pie chart, which is 29+137+58+62+74 and that will give you a total of 360 degrees
so, you say 360 degrees is equal to the total amount of money he spent, which is £720, what about 62 degrees
therefore, you just do (62×720)÷360
that will give you £124
Complex zeroes always occurs as conjugates.
For z = a + b i conjugate is: a - b i
Another zero is : 2 + 3 i.
Verification:
2 + 3 i + 3 - 3 i = - b/a
- b = 4, a = 1
( 2 + 3 i ) ( 2 - 3 i ) = c / a
4 - 9 i² = c / a
4 + 9 = c / a
c = 13
( x^4 - 4 x³ + 14 x² - 4 x + 13 ) : ( x² - 4 x + 13 ) = x² + 1
x² + 1 = 0
x² = -1, x = i, x = -i
The zeroes are: - i , i , 2 + 3 i, 2 - 3 i.
Answer:
One another zero of f ( x ) is 2 + 3 i.
-7 is the slope.
the slope formula is x2,y2-x1,y1
0-1=-1
11-4=7
the y goes on top of the x in the notation, so 7/-1 can be simplified to -7.
Hope this helps:)
Answer:
Part 1) The scale factor is 3
Part 2) The value of x is 36 in
Part 3) The value of y is 26 in
Step-by-step explanation:
step 1
Find the scale factor
we know that
If two figures are similar then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
so
In this problem
Let
z-----> the scale factor
step 2
Find the value of x
To find the value of x, multiply the length of 12 by the scale factor
so
step 3
Find the value of y
we know that
