The function y = 5x has a rate of change that is in between the equation y = 4x and y = 6x.
In an equation, the rate of change is also called the slope. It is the amount that a number is increasing by. We put that value in front of the x in most equations.
In the equal that I gave, the 5 is in between the rates of 4 and 6.
You want to isolate x. To accomplish this, add 1.4 to both sides of your eqn.:
x = 7.82 + 1.4 = 9.22 (answer)
Answer:
x = 17.5 and y = 35
Step-by-step explanation:
2x + 10 = y + 10 ( alternate angles )
subtract 10 from both sides
2x = y ⇒ 6x = 3y → (1)
the sum of the 3 angles in the triangle = 180°
6x + y + 10 + 30 = 180 ( replace 6x by 3y )
3y + y + 40 = 180
4y + 40 = 180 ( subtract 40 from both sides )
4y = 140 ( divide both sides by 4 )
y = 35
substitute y = 35 into (1)
2x = 35 ( divide both sides by 2 )
x = 17.5
Step-by-step explanation:
if you're looking for x
x=180-42-51= 87°
and if you're looking for D
D= 180-42= 138°
Answer:
240
Step-by-step explanation:
! means factorial or to multiply by the previous number down to one so 5!=5*4*3*2*1=120 120*2=240.
