Answer:
Tour 1: c1(x) = 35 + 10x
Tour2: c2(x) = 35 + 15x
The functions have the same initial value.
Do you agree?
12%. since this 24/ 200 if you just divide it by 2 you get 12/ 100 meaning 12%
Answer:
(-2, 3)
Step-by-step explanation:
4x + 5y = 7
3x - 2y = -12
Let's solve this by elimination. We want to eliminate one variable at a time. This means we need to multiply the equations to create a common multiple to cancel out a variable.
Let's work with y.
5y and -2y: For these values to cancel out, we need to multiply each term to create a common multiple.
2(4x + 5y = 7)
5(3x - 2y = -12)
Multiply.
8x + 10y = 14
15x - 10y = -60
Eliminate.
23x = -46
Divide both sides by 23.
x = -2
Now that we know x, let's plug it back into one of equations to find y.
4x + 5y = 7
4(-2) + 5y = 7
Multiply.
-8 + 5y = 7
Add.
5y = 15
Divide.
y = 3
Now we know x and y; let's plug both back into the equation we have not checked yet.
3x - 2y = -12
3(-2) - 2(3) = -12
Multiply.
-6 - 6 = -12
Subtract.
-12 = -12
Your solution is correct.
(-2, 3)
Hope this helps!
Carlos and Ana were asked to find an explicit formula for the sequence -10,-4,2,8,...−10,−4,2,8,...Minus, 10, comma, minus, 4, c
mars1129 [50]
Answer:
Ana is correct
Step-by-step explanation:
Given
Required
Determine who is right?
To do this, we simply test each sequence.
For Carlos:
When n = 1
When n = 2
<em>This is incorrect because the first and second term of the sequence are -10 and -4 not -4 and 2</em>
<em></em>
For Ana:
When n = 1
When n = 2
When n=3
When n = 4
This is correct.
<em>Hence, Ana is correct</em>
