Answer:
either 21 or 39 ion know this is confusing
Step-by-step explanation:
The interior of a triangle = 180°
So 180° - 85° -50° = 45°
c. 45 degrees
Answer: $336
explanation: 60% is equal to .6 so just take $210 and multiply that by .6 to get $126. Now, just take $126 and add it to $210 and you have $336.
13) As they’ve given the zeros, you can use those to create factors. Since the zeros are x=-1, x=-3, and x=4, by making the right side 0 in each equation, you get the factors (x+1), (x+3), and (x-4). Then, you can multiply those factors using box method or FOIL or whichever method you prefer. By multiplying (x+1) and (x+3), I got x^2+4x+3. Then, I multiplied that by (x-4) to get x^3-13x-12, which is your final answer.
14) Using the same steps in 13, I found the factors. As the zeros are x=-6 and x=0, I got the factors (x) and (x+6). Then, I multiplied them and got x^2+6x, which is the answer.
15) x=1, x=1, x=2. These become the factors (x-1), (x-1), and (x-2). Then, by multiplying (x-1) and (x-1) you get x^2-2x+1. Multiply that by (x-2) to get your final answer, x^3-4x^2+5x-2.
16) Zeros are x=-1, x=5, and x=-2. You get the factors (x+1), (x-5), and (x+2). Multiply (x+1) and (x-5) to get x^2-4x-5. Multiply that by the other factor, (x+2), to get your final answer, x^3-2x^2-13x-10.
Answer:
Step-by-step explanation:
Isolate the term of x and y from one side of the equation.
<h3>y=-15x-5 and 11x+y=-17</h3>
First, you have to substitute.
Then, you solve.
Add by 5 from both sides.
-4x-5+5=-17+5
Solve.
-17+5=-12
-4x=-12
Divide by -4 from both sides.
-4x/-4=-12/-4
Solve.
-12/-4=3
<u>x=3</u>
y=-15*3-5
Solve.
PEMDAS stands for:
- Parenthesis
- Exponents
- Multiply
- Divide
- Add
- Subtract
15*3=45
Rewrite the problem down.
y=-45-5
Solve.
<u>y=-50</u>
<u>Therefore, the correct answer is y=-50 and x=3.</u>
