Lets start from scratch.
45 is the number of money she spent that means that right side of = sign is 45
let m represents number of roses.
we can write:
t*$1+ m*$2 = $45
Since she bought 3 more tulips than roses that means that m = t - 3
when we express m we get:
t + 2*(t-3) = 45

Answer:
yes, it is a right triangle and ∡Q is the right angle
Step-by-step explanation:
if the slope of QR is the opposite reciprocal of QS then the two segments are perpendicular and form a 90° angle
slope of QR: -3 - (-1) ÷ 2 - 0 = -2 ÷ 2 = -1
slope of QS: -3 - (-1) ÷ 2 - 4 = -2 ÷ -2 = 1
-1 and 1 are opposite and reciprocal so m∡Q = 90°
The formula is
A=p (1+r)^t
A future value 6678
P present value 5300
R interest rate 0.065
T time?
6678=5300 (1+0.065)^t
6678/5300=(1+0.065)^t
Take the log for both sides
Log (6678/5300)=t×log (1+0.065)
Divide both sides by log (1+0.065)
T=(log(6,678÷5,300)÷log(1+0.065))
T=3.7 years
Hope it helps!
Answer:
The domain is all real numbers (see the explanation)
Step-by-step explanation:
we have
This is a vertical parabola open upward (the leading coefficient is positive)
The vertex represent a minimum
The vertex is the point (-5,-5)
we know that
The domain of a function is the set of all possible values of x
The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.
In this problem
The domain is the interval (-∞,∞)
The domain is all real numbers
The range is the interval [-5,∞)
All real numbers greater than or equal to -5
