Answer:
what do you mean it doesn't show for you?
Answer:
x=1+/-4i
Step-by-step explanation:
(x+1)/3-(2x-1)/x=-1
find the common denominator,
in this case, it's going to be 3x.
(x^2+x)/3x-(6x-3)/3x=-1
(x^2+x-6x+3)/3x=-1
x^2-5x+3=-3x
x^2-5x-(-3x)+3=0
x^2-5x+3x+3=0
x^2-2x+3=0
apply the quadratic formula in order to find the roots for x.
Since ax^2+bx+c=0, in this case,
a=1, b=-2, c=3
--------------------------
x=(-b+/-sqrt(b^2-4ac))/2a
x=(2+/-sqrt(4-12))/2
x=(2+/-8i)/2
x=1+/-4i
Answer:
12%
Step-by-step explanation:
The calculated value of a in the equtaion is a = 6
From the question, we have the following parameters that can be used in our computation:
7a-3=3+6a
Rewrite as
7a - 3 = 3 + 6a
Evaluate the like terms
So, we have
7a - 6a = 3 + 3
This gives
a = 6
Divide through the equation by 6
so, we have the following representation
a/6 = 1
Evaluate the quotient on the right hand side
a/6 = 1
Lastly, we have
a = 6
Hence, the value of a in the equtaion is 6.

the father takes, the son takes 5 steps just to keep up. What is the ratio of
the number of steps the father takes to the number of steps the son takes? Add
labels to the columns of the table and place the ratio into the first row of
data. Add equivalent ratios to build a ratio table.
2. What can you say about the values of the ratios in the table?
(p.s the image attached is for question 1)
Answer:
3:5 is the ratio.
Step-by-step explanation:
The ratio of the number of steps of father to number of steps of son is 3:5.
The table forms as follows:
Steps by father Steps by son
3 5
6 10
9 15
12 20
15 25
a) The ratio of the number of steps of father to number of steps of son will be 3:5.
b) The table forms as follows:
father son
3 5
6 10
9 15
12 20
15 25
a) We can continue finding equivalent ratios by multiplying both sides of the ratio by different numbers, such as 3, 4, or any other value.
Multiply the first term by 2 to get 3 * 2 = 6. Multiply the second term by 2 to get 5 * 2 = 10.
- The equivalent ratio is 6:10.
In the ratio table, we can observe that the values of the ratios are always in the form of a fraction or as a simplified fraction.
=The ratios we have found so far, such as
3:5 and 6:10, = 3/5 and 3/5 respectively.
Thus the ratio of the number of steps of father to number of steps of son is 3:5.
b) The table forms as follows:
father son
3 5
6 10
9 15
12 20
15 25
