Answer:
-11x
Step-by-step explanation:
-10x - x
Due to -10x being negative, you would add -x and it would then be -11x.
Answer:
Step-by-step explanation:
As square roots has to be positive, there is no positive value for x which will satisfy the equation. As there is also a negative number outside the square root, the graph will have negative y-values for every x-value.
Answer:
5log(a) +2log(b)
Step-by-step explanation:
you were close, but you dont multiply the exponents together since a and b are two different variables
Answer:
I. First number, a = 40.
II. Second number, b = 50.
III. Third number, c = 120.
Step-by-step explanation:
Let the three numbers be a, b and c respectively.
Given the following data;
Translating the word problem into an algebraic equation, we have;
a + b + c = 210
b = a + 10
c = 3a
Substituting the value of b and c into the equation, we have;
a + a + 10 + 3a = 210
5a + 10 = 210
5a = 210 - 10
5a = 200
a = 200/5
<em>a = 40</em>
To find the value of b;
b = a + 10
b = 40 + 10
<em>b = 50</em>
To find c
c = 3a
c = 3*40
<em>c = 120</em>
.45x+.55x=200
Combine like terms
1x=200
So x is 100
Or you can do 45%+55%=100%
And 100% of 200 is 200
