Answer:
When a point gets reflected across the x-axis, the sign of its y-coordinate changes so the coordinates of Q' are (3, 4).
The value of x according to the equation in the task content is; -5.35 or -10.65.
<h3>What is the value of x in the equation?</h3>
The equation given in the task content is; (x + 8)² -7 = 0.
Hence, the equation can be solved as follows;
(x + 8)² - 7 = 0
x² + 16x +64 -7 = 0
x²+ 16x +57 = 0
By solving by means of the quadratic formula, we have;
x = -5.35
x = -10.65

thanks for the points
Step-by-step explanation:
So percent means parts out of 100
5%=5/100=0.05
it depends if this is simple interest or compound
simple interest is find 5% of 600 and every year just give you that 5%
compound is find 5% then add that to 600, then next year find 5% of that new amount
so if simple
5% of 600=5/100 times 600=30
2 years
so add 30 times 2=60
600+60=660 total
if compound
5% of 600=5/100 times 600=30
new amound=630
year 2
5% of 630=5/100 times 630=31.5
new amount=661.5
if simple interest then $660.00
if compound then $661.50
