Answer:

Step-by-step explanation:
Area of any triangle could be always calculated as base length multiplied by the height perpendicular to the aforementioned base divided by 2. Therefore:
A = 18 * 11 / 2 = 198 / 2 = 99
Mercury has the greater density than that of Venus .
Using the law of cosins
sin(angle) = Opposite Leg / Hypotenuse
The angle is given as 35 degree and the hypotenuse is given as 30 feet.
Sin(35) = X ( opposite leg) / 30
X = 30 * sin(35)
x = 17.2 feet.
Total height = 17.2 + 6.5 = 23.7, round to 24 feet.
The answer is 24 feet.
Answer:
y = 2x + 1 --> linear
y = -4x + 7 --> non-linear
Not a solution for linear system.
Step-by-step explanation:
for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:
7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.
for (b), we have to substitute our values again. You get:
7 = -4x3 + 7, which is
7 = -12+7, which is not true. So, (b) is not linear.
This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.
Cost of tablet $315
monthly payments of $25
a. 315 - 25 = $290
b. After each payment, the amount owed decreases. Therefore, the balance decreases.
second part of this: write equation for calculating the amount owed a for any number of payments n $ $25(n-1) =a
I cant draw a graph on here for you, but as n increases, then a decreases
d. as n increases by 1, how does a change? Answer: A decreases by $25 each time n increases by one
e. He will need to make 12.6 payments
