Answer:
Step-by-step explanation:
1) 2x + y =7 -------------(I)
x - y = 2 -----------(II)
2x + y = 7
<u> x - y = 2 </u> {Now add both the equations. 'y will be cancelled}
3x = 9
x = 9/3
x = 3
Plugin x = 3 in equation (I)
2*3 + y = 7
6+ y = 7
y = 7 - 6 = 1
Answer: a) y = 1
2) Prime factorize 12 , 15 and 18
12 = 2 * 2 * 3
15 = 3 * 5
18 = 2 * 3 * 3
HCF = 3
e) 3

Answer:</h3>
There are 75 birds in each section
<h3>
Step-by-step explanation:</h3>
First, lets see how many in each enclosure so we have an amount to multiply by 3
450/18 = 25 birds per enclosure.
Now lets see how many birds would be in 3 enclosures i.e. a section
25 * 3 = 75
Answer:
Step-by-step explanation:
To figure out the midpoint, you need to plug the coordinates into the midpoint formula.
M (x1 + x2 / 2, y1 + y2/2)
M [ 2 + (-3)/2, 5 + 9/2]
M ( -1/2, 7)
18 x c= p

Scale Factor is defined as the ratio of the size of the new image to the size of the old image. The center of dilation is a fixed point in the plane.
If the scale factor is more than 1, then the image stretches. If the scale factor is between 0 and 1, then the image shrinks. If the scale factor is 1, then the original image and the image produced are congruent.
To dilate a figure by a scale factor, all the coordinates are multiplied by the scale factor.
The coordinates of point A are (8, 6). A dilation by a scale factor of 0.5 means that the figure will be reduced. The new coordinates will be:A
Therefore, the FIRST OPTION is correct.
