Answer:
-9, 2/5
Step-by-step explanation:
1. Distribute
7i × 5 + 7i × -9i
2. Simplify 7i × 5 to 35i
35i + 7i × -9i
3. Simplify 7i × -9i to -63ii
35i - 63ii
4. Use the Product Rule
35i - 63i^2
5. Use the Square Rule
35i - 63 × -1
6. Simplify 63 × -1 to -63
35i - (-63)
7. Simplify brackets
35i + 63
8. Regroup terms
63 + 35i

a dilation with a scale factor of 4, is multiplication by 4 each side, so we need the measure of the side CD and then multiply by 4 to find C'D'
we can notice tht length of CD, is 3 squares,multiplying by 4 the new length is 3x4= 1 2 squares
The graph is showing the equation of circle x²+y²=4
<h3>What is a circle?</h3>
A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point.
The given graph in the question represents the equation of the circle cutting the points on the x-axis and y-axis at 4 which is the radius of the circle.
The equation will be as follows:-
x²+y²=4
Hence the graph is showing the equation of circle x²+y²=4
