Answer:
The image is (-18,0)
Step-by-step explanation:
Here, we want to find the image of the given point after dilation by the given scale factor
Mathematically, given a point with the pre-image (x,y) going under the dilation of scale factor k, centered at the origin, the coordinates of the image will be;
(kx , ky)
Applying this in the given scenario, we have
(2(-9) , 2(0))
= (-18,0)
Answer:
#3
Step-by-step explanation:
Answer:
c. -1.5 < -0.5
Step-by-step explanation:
a. -1.5 > 0.5 . . . . false
b. -0.5 > 0 . . . . . false
c. -1.5 < -0.5 . . . TRUE
d. 1/2 > 0.5 . . . . false (these are the same number) 1/2 = 0.5
_____
In order on the number line from left to right, you will see ...
(left end) ... -1.5 ... -0.5 ... 0 ... 0.5 ... (right end)
__
The inequality relation appropriate to these is ...
(number on the left) < (number on the right)
Of course, this can be swapped around so you have ...
(number on the right) > (number on the left)
Answer:Mark Is 9 years old; Christine is 5 years old
Step-by-step explanation:
Present age
LET mark age be x
Christine be x-4 yrs
In 3 yrs Time
Mark will be x+3 yrs old
Christine will be (x -4 +3) = x-1 years old
Also, In 3 years time
Christine = 2/3 Mark
such that
x-1 = 2/3(x+3)
x -1= 2x+6 / 3
3x -3= 2x+6
3X--2X = 6+3
=X=9
Mark Is 9 years old
Christine is x -4 = 9-4=5 years old
