Answer:-7^2(negitive seven to the second power)
Step-by-step explanation:
if i didn't understand it wrong, * is (3-5) x (2)
so,
(3-5)x 2-16-2
=-2x2-16-2
=-4-16-2
= -22
But if * means (3-5)^2 -16-2
then its,
(3-5)^2-16-2
=(-2)^2 -18
=4-18
= - 14
But looks like both of them are not in your choice at all
Answer:
Step-by-step explanation:
When x=-1
Substitute into the given equation
3(-1)-5y=19
-3-5y=19
Add 3 to both sides
-5y=22
Divide both sides by-5
y=-22/5
When x=0
3(0)-5y=19
0-5y=19
-5y=19
Divide both sides by-5
y=-19/5
When x=1
3(1)-5y=19
3-5y=19
Substrate 3 from both sides
-5y=16
Divide both sides by-5
y=-16/5
Therefore when x=-1,y=-22/5
When x=0,y=-19/5
When x=1,y=-16/5
Answer:
the real answer is c but it may b also
Use the points H(−4, 1) and K(4, 1).
(a) From two points , we will get a vertical line when 'x' values are same and horizontal line segment when 'y' values are same
Here in H(−4, 1) and K(4, 1) , the y values are same so the segment HK is a horizontal . The length is the difference between x values ( 4 -(-4)) = 8
Segment HK is a Horizontal segment that is
8 units long.
(b) Describe the image of segment HK under the transformation
(x, y) -----> (−y, x)
H(−4, 1) -----> (-1, -4)
and K(4, 1) ---> (-1, 4)
'x' values are same so line HK is Vertical. The length is the difference between y values ( 4 -(-4)) = 8
The image of segment HK is a Vertical segment that is
8 units long.
(c) escribe the image of segment HK under the transformation
(x, y) ----> (2x, y)
H(−4, 1) -----> (-8, 1)
and K(4, 1) ---> (8, 1)
'y' values are same so line HK is Horizontal. The length is the difference between y values ( 8 -(-8)) = 16
The image of segment HK is a Horizontal segment that is
16 units long.
