Alright, let's do all of these (though this is a bit long).
1.
The constant is 1.8. All other values are coefficients to variables, which as the name implies will change.
2.
1 hour is 60 minutes, 1 minute is 60 seconds.
So, 4.2 *60 *60 = 15120 seconds.
3.
<span>−5x−4(x−6)=−3-5x-4(x-6)=-3
Let's move all x to one side, and all other numbers to another.
-5x-4(x-6)=-3-5x-4(x-6)=-3
x can be any value you want, if you actually solve this you'll only end up with -3 = -3, which is correct, of course.
Let me show you:
</span><span>−5x−4(x−6)=−3-5x-4(x-6)=-3
+5x +4(x-6) +5x +4(x-6)
-3 = -3
The value of x is irrelevant, then. X can be any real number.
4.
I'm going to assume it was an error in printing with this? If not please correct me.
m=a+2b(or b2)
subtract 2b from each
a=m-2b
(This question seems kind of odd. We should probably address this in the comments.)
5.
</span><span>5(x−2)<−3x+6
Move all x to one side, numbers to other.
5x-10<-3x+6
+3x +3x
+10 +10
8x<16
/8
<span>x < 2
</span>6.
y-3=3(x-5)
alright, to find zeros set one variable to zero and solve
x first
-3=3x-15
+15 +15
3x=12
/3
x=4
x-int is (4,0)
now y
</span>y-3=3(0-5)
y-3=-15
+3 +3
y=-12
so y-int is (0,-12)
i've got to sleep now so i'll do the rest tomorrow. Sorry for the incomplete answer.
Answer:
20
Step-by-step explanation:
When looking for the perimeter just add all the numbers together.
The answer would be the first option (2.2, -1.4) it is the closest to where the two meet. Can I plz have brainliest? i need it
Answer: If the left side and the right side of the equation are equal, the equations has infinitely many solutions.
Step-by-step explanation:
The options are not clear, so I will give you a general explanation of the procedure you can use to solve this exercise.
The Slope-Intercept form of the equation of a line is the following:
Where "m" is the slope and "b" is the y-intercept.
For this exercise you need to remember that, given a System of Linear equations, if they are exactly the same line, then the System of equations has Infinitely many solutions.
If you have the following system:
You can simplify the second one:
Then, both equations are the same line.
By definition you can also write the systemf making both equations equal to each other:
So, if the left side and the right side are equal, the equations has infinitely many solutions.
Answer:
3
Step-by-step explanation:
Given the polynomial : p(x)=1−2x2−3x3+4x
Rearranging : p(x) = -3x³ - 2x² + 4x + 1
Looking at the polynomial Given, we can see that it is a univariate polynomial, that is it has only one variable which is x. Thus for polynomials of this sort, the order of the polynomial is the highest exponent occurring in the polynomial equation. Therefore, the order of the polynomial above is 3, because the highest power of the function is 3.
This means that those with 4 as their highest exponent are of order 4 and those with highest exponent as 2 are of order 2.
