Answer:
The exponent of y is 1
Step-by-step explanation:
Given
Required
Convert to fractional exponent
Here, we simply apply the following law of indices:
So, the expression becomes:
<em>From the above expression, the exponent of y is 1</em>
Answer:
$221
Step-by-step explanation:
Hello!
The total cost s $627.83, for one desk that costs $185.83, and two identical chairs (c).
The equation: $185.83 + 2c = $627.83
This equation represents the cost of the desk plus two chairs of the same price, which adds up to the total price.
Solve for c:
- $185.83 + 2c = $627.83
- 2c = $442
- c = $221
Each chair, c, costs $221.
The roots routine will return a column vector containing the roots of a polynomial. The general syntax is
z = roots(p)
where p is a vector containing the coefficients of the polynomial ordered in descending powers.
Given a vector
which describes a polynomial
we construct the companion matrix (which has a characteristic polynomial matching the polynomial described by p), and then find the eigenvalues of it (which are the roots of its characteristic polynomial)
Example
Here is an example of finding the roots to the polynomial
--> roots([1 -6 -72 -27])
ans =
12.1229
-5.7345

Answer:
6) x = 36°, y = 18°
7) z = 7°
Step-by-step explanation:
6) 2x + 3x = 180°
5x = 180°
x = 36°
4y = 2x = 72°
y = 18°
7) 2z + 4 = 4z - 10
2z = 14
z = 7
Answer:
Y=3x-2
Step-by-step explanation:
The equation of the line is y=ax+b
The slope is 3 so we got a:
Y=3x+b
Now we end to find b.
If we plug in the point (-2,-8) into the equation we have:
-8=-6+b
Solving for b we have
B=-2
So the equation is
Y=3x-2
