Lets write this into an expression.
-2x = -24
Now, lets solve for x.
~Divide -2 to both sides
-2x/-2 = -24/-2
~Simplify
x = 12
Best of Luck!
Answer:
The answer is 12
Step-by-step explanation:
Step 1: Convert words into an equation
What do you is you multiply -2 by something to get -24
-2 * something = -24
We can represent something with a variable called x.
-2 * x = -24
-2x = -24
Step 2: Solve for x by dividing both sides by -2
-2x / -2 = -24 / -2
x = 12
Answer: The number we can multiply -2 by to get -24 is 12
Answer:
The value of w is 5.
Step-by-step explanation:
To find the value of w, we start with the slope equation. Then, we input all of the values we are given.
m(slope) = (y2 - y1)/(x2 - x1)
-8 = (7 - -1)/(w - 6)
-8 = 8/(w - 6)
Now to solve for w, we need to cross multiply.
-8(w - 6) = 8
w - 6 = -1
w = 5
To find the value 'w', we use the equation for calculating the slope of a line given two points. After placing the known values into the equation, we solve for 'w' and find that w = 5.
To solve for w, we utilize the formula for the slope of a line given two points (x1, y1) and (x2, y2), which is (y2-y1)/(x2-x1). In our case, we know the slope is -8, and we have one point (6, -1) and another point (w, 7).
So, we set up the equation -8 = (7 - (-1)) / (w - 6). Simplifying this gives -8 = 8 / (w - 6). Cross multiply gives -8*(w - 6) = 8, which simplifies to -8w + 48 = 8. Subtracting 48 from both sides gives -8w = -40, so w = 5.

Enter the correct answer.
Answer:
Vertex of parabola (-1, -10)
Step-by-step explanation:
For a given quadratic y = ax² + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k. If you've already learned the Quadratic Formula, you may find it easy to memorize the formula for k, since it is related to both the formula for h and the discriminant in the Quadratic Formula: k = (4ac – b2) / 4a.
