I think you got to multiply the numbers hopefully I helped
Answer:
x = 34
Step-by-step explanation:
This is a straight line so the sum of angles must be 180°
4x + 20 + x - 10 = 180 add like terms
5x + 10 = 180 subtract 10 from both sides
5x = 170 divide both sides by 5
x = 34
To calculate each angle we replace x with the value we found
4x + 20 ➡ 4×34 + 20 = 156
x - 10 ➡ 34 - 10 = 24
X^2(x)+5x(x)+6/x(x)+1(x)=1(x)
X^3+5x^2+6+x=x
X^3+5x^2+6=0
Use cube
X is approx -5.220181
<h3><u>-2 + 6 = 4</u></h3><h3><u>0 + 6 = 6</u></h3><h3><u>5 + 6 = 11</u></h3>
Answer:
f(-2.75)=-1
Step-by-step explanation:
Here we are given a Greatest Integer Function . The characteristic of this function is that it when operated , gives you the greatest integer it has near to it.
Hence if we have any greatest integer function f(x)=[x] , for x = -2.75
[-2.75]=-2 , as -the greatest integer near to -2.75 is -2 as -3<-2
Now coming back to our problem, our function is
f(x)=[x]+1
Hence for x=-2.75
f(x)=[-2.75]+1
as we discussed above [-2.75]=-2
Hence
f(-2.75)=-2+1
f(-2.75)=-1
