Evaluate each algebraic expression for x = -2,3, -0.5, and 1 1/2
2). 4X. 3) 3x+2
PLEASE HELP URGET!!
Answers
Answer:
Step-by-step explanation:
2. 4x= 4*(-2)=-8
4x=4*(3)=12
4x=4*(-0.5)=-2
4x=4*3/2=6
the 3x+2
3x+2=3*(-2)+2=-6+2=-4
3x+2=3*(3)+2=11
3x+2=3*(-0.5)+2=-1.5+2=0.5
3x+2=3*(3/2)+2=9/2+2=13/2=6 1/2

Arian has 780 in a savings account that earns 2.5% simple interest annually. How much money will be in her account if she does not make any deposits or withdrawals in 2 years?
Answers
Answer:
819
Step-by-step explanation:
We solve the above question using simple interest
The formula for the total amount in a bank amount when it earn simple interest annually is:
A = P(1 + rt)
When
P = Initial amount in the account = 780
r = Simple Interest rate = 2.5% = 0.025
t = 2 years
A = 780(1 + 0.025 × 2)
A = 780(1 + 0.050)
A = 780(1 .050)
A = 819.00
The amount of money that will be in her account if she does not make any deposits or withdrawals in 2 years is 819.

The area of a circle is 379.94m². Using 3.14 for π, find the circumference of the circle.
Answers
Answer:
69.08
Step-by-step explanation:
The equation for circumference is C = 2πr and the equation for area is A = πr^2. First, do 379.94 = 3.14r^2. This means that r^2=121 so r=11. Now plug it in to C=2πr so it becomes C=2π(11). So C=22π or 69.08.
Question:
Find the circumference of the circle. Use 3.14 for π.
5 in.
Answer:
15.7 inches
Step-by-step explanation:
Identify the diameter of the circle.
d = 5 in.
Use the formula.
C = πd
C = π(5) Substitute 5 for d.
C ≈ 3.14(5) Substitute 3.14 for π.
C ≈ 15.7 Multiply.
The circumference of the circle is about 15.7 inches.

In a right triangle the length of a hypotenuse is c and the length of one leg is a, and the length of the other leg is b, what is the value of b, if c=13, a=5
Answers
9514 1404 393
Answer:
b = 12
Step-by-step explanation:
A commonly seen "Pythagorean triple" is (a, b, c) = (5, 12, 13).
The value of b is 12.
__
You may be expected to find this using the Pythagorean theorem.
a² +b² = c²
b² = c² - a²
b = √(c² -a²) = √(13² -5²) = √(169 -25) = √144
b = 12
_____
Additional comment
Pythagorean triples you will run across are ...
(3, 4, 5), (5, 12, 13), (7, 24, 25), (8, 15, 17), (9, 40, 41)
and their multiples, such as 2×(3, 4, 5) = (6, 8, 10). Of course, there are an infinite number of integer Pythagorean triples, but these are ones commonly seen in algebra, trig, and geometry problems.

4x-2+y-4
Step-by-step explanation:
Answer:
x = 7, y = 16
Step-by-step explanation:
the sides with measure 2x + 5 and x + 12 are congruent, so
2x + 5 = x + 12 ( subtract x from both sides )
x + 5 = 12 ( subtract 5 from both sides )
x = 7
Then
x + 5 = 7 + 5 = 12
The sides with measure y - 4 and x + 5 are congruent, so
y - 4 = x + 5, that is
y - 4 = 12 ( add 4 to both sides )
y = 16

Answer:
c = 2.99m+ 6.85
Step-by-step explanation:
one time fee of 6.85
2.99 per movie rental
in other words you must pay 6.85
and 2.99 times the number of movies you watch
m = movies watched
c = cost
therefore
c = 2.99m+ 6.85
watching 13 movies at movie mania would mean that m (movies watched) would be 13
put that into the equation:
c = 6.85+ 2.99(13)
c = 6.85+ 38.87
c = 45.72
