A triangle is always 180 degrees. We know that one side is 50 degrees and two of our sides are equal so we can be sure that the other side is 50 degrees this gets us to 100 degrees leaving 80 degrees this means x= 80
Answer:
slope= -¾
Step-by-step explanation:
3x +4y= 9
Let's rewrite the equation into the form of y= mx +b (known as slope-intercept form), where m is the slope and b is the y-intercept.
Keep the y term on the left-hand side of the equation and move all the other terms to the right-hand side.
4y= -3x +9
For the coefficient of y to be 1, divide both sides of the equation by 4.
Answer:
x=-2
Step-by-step explanation:
2(3x – 1) = 4x - 6
Distribute
6x-2=4x-6
Moving like terms (4x)
2x-2=-6
Moving like terms (-2)
2x=-4
Divide both sides by 2 to isolate x
x=-2

We are asked to evaluate the given expression 3 (r² + t) - r² given that r is equivalent to 2 and t is equivalent to 7. The solution to this problem is shown below:
3 (r² + t) - r² , substitute r=2 and t=7 in the expression
3 (2² + 7) - 2² , perform squared
3 (4+7) -4, perform addition of 4 and 7
3 (11) -4, perform multiplication os 3 and 11
33 - 4, perform subtraction
29
The answer is 29.
Answer:
None of them
Step-by-step explanation:
A polynomial must have a pronumeral that is to the power of an integer, and you can't divide by a variable such as 2/x so for
a) there is a 
which means it's not a polynomial as is the same as 
b) The second term is being divided with a variable so that can't be a polynomial
c) There is a 
so it can't be a polynomial
d) There is a 
so it can't be a polynomial
