Answer:
50.5
Step-by-step explanation:
2xy+2x^2 And we know x=-2.5 and y=-7.5.
In order of operations, exponents come first.
x^2 = -2.5 * -2.5 = 6.5.
6.5*2=13.
2xy + 13
2x=-5
-5*-7.5 = 37.5
37.5 + 13
50.5
Remember you can do anything to an equation as long as you do it to both sides
2x+3(x-4)=x-20
first distribute
2x+3(x)+3(-4)=x-20
2x+3x-12=x-20
5x-12=x-20
minus x both sides
4x-12=-20
add 12 to both sides
4x=-8
divide both sides by 4
x=-2
any triangle should end up being 180degrees so,
67+48=115
180– 115= 65
so the x should equal 65
hope this helps
Answer:
y = -19
Step-by-step explanation:
The equation has a negative slope (-3). This means the y value decreases as x increases. Since the maximum value for x is 5 (≤5), we know that the value produced when x = -5 will result in the smallest value of y.
In this case,
y = -3x - 4
y = -3(5) - 4
y = -19
