First, open the parentheses (make sure you distribute the '-':
6x - 3x - 4 = x - 40
3x - 4 = x - 40
2x = -36
x = -18
The solution set is {-18}
Answer:
1. Equivalent
The rest are not
Step-by-step explanation:
This is my thinking, sorry if I got it wrong...
In the first pair, 6 will be multiplied by 5, which is 30, the 6 will be multiplied by x as well. The second one is not equivalent as 4 is not multiplied. The last one is that y did not get multiplied.
126.56 feet
This can be found by finding the vertex of the parabola. You can find the t value using -b/2a and then plug that in to find the h value.
Answer:
I need the function and graph to be able to answer this
Step-by-step explanation:
Answer:
All the others are 90 degrees too
Step-by-step explanation:
In a parallelogram opposite angles are congruent. Also in a quadrilateral the sum of angles is 360 degrees. since their are two pairs of congruent angles you could make an equation and it would look like this: 180+2x =360. x would be 90 making every angle 90 degrees
