4x-10=6x+4; -10=2x+4; -14=2x; x=-7
Answer:
S(7, -37)
Step-by-step explanation:
Let the coordinates of point S be (x, y).
(14 + x)/2 = 7
14 + x = 14
x = 0
(21 + y)/2 = -8
21 + y = -16
y = -37
Answer: 6%
Step-by-step explanation:
Principal= $1875
Time= 10 years
Interest= $1125
Rate = Unknown
Recall that,
Interest= (Principal×Rate×Time)/100
I = PRT/100
100I = PRT
R= (100×I)/PT
Rate = (100 × 1125)/(1875 × 10)
Rate = 112500/18750
Rate= 6%
The rate is 6%
• Move x to the other side
7y=21-3x
• Divide by 7
y = (21-3x)/7
Answer:
312
Step-by-step explanation:
First we find the measure of the basea and that is 144 becuase 12x12
To find one side we do b*h over 2 and that is 7x12/2 which is 42 then we know that there are 4 more of those sides and we get 42*4 168
When we add 144+168 we will get 312
