Answer:
A. The solutions are 
.
B. The factored form of the quadratic expression 
Step-by-step explanation:
A. To find the solutions to the quadratic equation 
you must:
The solutions are:
B. Two expressions are equivalent to each other if they represent the same value no matter which values we choose for the variables.
To factor 
:
First, multiply the constant in the polynomial by 
where is equal to -1.
Since both terms are perfect squares, factor using the difference of squares formula
Answer:
x=1 & y=6 or (1,6)
Step-by-step explanation:
3x-x+5=7 Substitute the 2nd equation in for y
2x+5=7 Do 3x-x to get 2x
2x=2 Subtract 5 from both sides
x=1 Divide 2 from both sides
y=1+5 Insert 1 as x
y=6 Add 1+5 to solve for y
Hope this helped!
So with this, I will be using the substitution method. With the first equation, substitute (y+3) into the x variable and solve for y:
Next, now that we have the value of y, substitute it into either equation to solve for x:
<u>And this is how you get your final answer (5,2).</u>
Answer:
V = 314.2 ft^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h r is the radius (5) and h is the height (4)
Using the pi button for pi
V = pi (5^2) (4)
V =314.1592654
Rounding to the nearest tenth
V = 314.2 ft^3
4.93
^ This number is less than 5, so we round down to 4.9.
