Can you make this clearer so i can understand
Answer:
<u>23/2 units</u>
Step-by-step explanation:
Points are :- (-21/2, -3) and (1, -3)
Distance = √(y₂ - y₁)² + (x₂ - x₁)²
= √(-3 + 3)² + (1 + 21/2)²
= √(23/2)²
= <u>23/2 units</u>
Answer:
x=3/2y-6
Step-by-step explanation:
3y=2x=12
-3y -3y
-2x=-3y+12
^divided by -2 on both sides
x=3/2y-6
Answer:
B
Step-by-step explanation:
The solutions to a quadratic equation is whenever the graph crosses the x-axis. The solutions are also known as the roots or zeros of the quadratic.
Our quadratic crosses the x-axis at -3 and 1. So, at those two points, f(x) is 0. Namely, we have the two points (-3, 0) and (1, 0).
So, our two solutions are -3 and 1.
Hence, our answer is B.
Answer:
x = 2
y = 1
z = 3
Step-by-step explanation:
Okay, we know y=z-x.
Let's plug in that y-value into the first equation: x + 2 (z - x) -z =1
Simplify that down to x +2z -2x -z = 1
Equation 1 becomes -x + z = 1
Let's plug it into equation 3 and solve to get: 2x - (z - x) +3z = 12
Equation 3 becomes 3x + 2z = 12
Now let's use system of equations for those two equations we just found
3x + 2z = 12
-2x + 2z = 2 ------> multiplied this by 2 to simplify
subtract, and you 5x = 10, x = 2
Use x = 2 and solve for the other variables using the same method (try this on your own!) to get y = 1 and z = 3
