General Formulas and Concepts:
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
- Solving systems of equations using graphing
Step-by-step explanation:
To find the solution set of a systems of equations, the point where the 2 lines intersect would show the solution for the systems.
According to the graph given, both lines intersect each other at x = -1.
Therefore, our answer is B.
Points: (0,4) and (2,-3)
Find slope: (-3-4)/(2) = -7/2
4 = -7/2(0) + b, b = 4
Equation: y = -7/2x + 4
Answer:
first you have to finish the problem
Step-by-step explanation:
Hello!
We can solve this using trigonometric functions. We will be referring to the 70 degree angle. We need to solve for the hypotenuse. We have the length of the opposite side and need to find the hypotenuse. Therefore, we use the sine.
sin70=12/x
Since we cannot immediately solve for x, we will simplify this equation. We multiply both sides by x.
x(sin70)=12
Divide both sides by sin70.
x=12/sin70
Now we solve this equation.
12/sin70≈15.51
Therefore, x=15.51 cm.
I hope this helps!
Answer:
152 (Answer A)
Step-by-step explanation:
The experimental probability of obtaining a head is 19/100, or 0.19.
If the coin is flipped 800 times, the expected number of heads will thus be:
0.19(800 flips) = 152 (Answer A)
