Answer:
x = 19
Step-by-step explanation:
Let's convert the given statements into algebraic expressions.
R is five more than twice x:
R = 2x + 5
S is one more than x:
S = x + 1
T is sixteen less than seven times x:
T = 7x - 16
Also, we know, the sum of 3 angles in a triangle is ALWAYS EQUAL to 180 degrees. Thus we can write:
R + S + T = 180
Substituting the expressions, we have:
2x + 5 + x + 1 + 7x - 16 = 180
Now we do algebra and simply solve for x. Shown below:
Hence, x = 19
Answer:
y=mx+b
m = slope
b = y-intercept
To find slope we use the equation, change in y divided by the change in x. Let's use points (2, 2) and (3, 1).
(2-1) / (2-3) = -1
Meaning our slope is -1 and it will be going down.
Next, we have to find the y-intercept which is the value of y when x=0. When x is 0 y will be 4.
y=-1x+4

Answer:
2y^3-7y^2+7y
Step-by-step explanation:
7y - 2y^3 + 5y^2 - ( 12y^2 – 4y^3)
Distribute the minus sign
7y - 2y^3 + 5y^2 - 12y^2 + 4y^3
Combine like terms
2y^3-7y^2+7y
