If AB is twice as large as A'B', the scale factor must be 0.5 to get from AB to A'B':
Answer:
(9, -5)
Step-by-step explanation:
The vector AC has coordinates (27, -18), because:
21 - (-6) = 27
-13 - 5 = -18
If the ratio of AB to BC is 5 to 4, it means that
AB = [5/(5+4)]AC = (5/9)AC
Therefore, we have
AB = (5/9)AC = (5/9) (27, -18) = (15, -10)
Which means that:
xB - xA = 15 <=> xB - (-6) = 15 <=> xB + 6 = 15 <=> xB = 9
yB - yA = -10 <=> yB - 5 = -10 <=> yB = -10 + 5 <=> yB = -5
So B has coordinates (9, -5).
Answer:
y= -(3/2)x -5
Step-by-step explanation:
Divide both sides by negative 2
-2y=3x+10
This halves the 3 and the 10 resulting in (3/2) and 5 values, since they are positive integers dicided by a negative integer they become negative. Negative 2 divided by begative two becomes positive 1 since negatives cancel each other out.
y= -(3/2)x -5
Answer:
Step-by-step explanation:
This is exponential growth which has the form
Answer:
-7
Step-by-step explanation:
-7
EXPLANATION
The only numbers that have a distance of 7 from zero on the real number line are -7 and 7.
-7 is to the left of zero while 7 is to the right of zero.
But this two numbers are all 7 units from zero.
In other words, the absolute values of this numbers is 7.
