Answer:
7
Step-by-step explanation:
If you plug in the variable for x and y you get:
5+3-1
Use the order of operations to solve:
5+3-1
8-1
7
If x =-3 that means the equation becomes
Y=2(-3) +1 and when you simplify you get
Y=-5 hope this helps :)
Answer:
10.
Step-by-step explanation:
To find the distance between two numbers, subtract the two numbers. The absolute value of the difference is the distance.
The absolute value of -10 is 10.
Therefore, distance between -7 and 3 is 10.
Let the measure of the angle be x and from that the measure of its complement is 90 - x. The equation that best represent the given condition above is,
3x = (90 - x) - 14
The value of x from the equation above is 19. Thus, the answer is letter A.
Answer:
width = 8, length = 42
Step-by-step explanation:
Let x = width, then length = 4x+10.
A = l x w
336 = x(4x+10) put into standard form
4x2 + 10x - 336 = 0 divide by 2
2x2 + 5x - 168 = 0 and solve using the quadratic formula and get
-21/2 and 8, the neg answer will not work, so the width = 8, length = 42
