Fiona is completing the square to solve the polynomial
equation.
What should be her first step?
x2 - 4x + 1 = 0
isolating the constant 1
O adding 4 to both sides of the equation
O isolating the second term, 4x
adding 1 to both sides of the equation
Answer:
isolating the constant 1
Step-by-step explanation:
The first step in solving the equation via completing the square is to isolate the constant.
What is completing the square method?The term completing the square method refers to one of the popular methods of solving quadratic equations that involves the addition of half of the square of the b term to both sides of the equation.
Given that an equation, x²-4x+1 = 0, we need to find the first step to solve this be using completing the square method,
So, according to the definition, we will add first isolate the constant,
Therefore,
x²-4x+1 = 0
x²-4x = -1
Now, we will add 4 to both the side,
x²-4x+4 = -1+4
(x+2)² = 3
x+2 = ±√3
x = √3-2 or x = -√3-2
Hence, the first step in solving the equation via completing the square is to isolate the constant.

A room has a length of 7 m.
A scale diagram is drawn of the room.
In the diagram, the room has a length of 1 cm.
What is the scale of the diagram?
Give your answer as a ratio in the form 1 : k, where k is an integer.
Answer:
Step-by-step explanation:
A ratio is used in scale drawings of maps and buildings.
That is:
The scale of a drawing = Drawing Length : Actual Length
A scale is usually expressed in one of two ways:
-using units as in 1 cm to 1 km
-without explicitly mentioning units as in 1 : 100,000.
A scale of 1 : 100,000 means that the real distance is 100,000 times the length of 1 unit on the map or drawing.
In your case, where the room has a length of 7m and 1cm on the diagram:
1 cm to 7m = 1cm : 7m
= 1cm : 700cm
= 1 : 700
Solve the inequality. −2≤x−11≤6
Answer:
9≤x≤17
Step-by-step explanation:
In order to solve this equation, you need to just add 11 to each side
-2≤x-11≤6
to
9≤x≤17
The reason that 11 was added to this equation was that we were trying to isolate x, and it goes without saying that (x-11)+11 is x . 11 was added to the other sides because it is an inequality and that will keep it balanced.
The value of the variable 'x' will be more than or equal to 9 and less than or equal to 17.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The inequality is given below.
−2 ≤ x − 11 ≤ 6
Add 11 on each side of the inequality. Then we have
−2 + 11 ≤ x − 11 + 11 ≤ 6 + 11
9 ≤ x ≤ 17
The value of the variable 'x' will be more than or equal to 9 and less than or equal to 17.

The equation is y = mx + b. b is the y intercept, which means the line intersects the y axis at 50, not the x axis. Also, the equation is an inequality and you wrote an equation. The inequality should be 100 ≥ 4x + 50, or 50 ≥ 4x. If y = 4x + 50, then 100 ≥ y.
Also, in the end you got 12.5. 12.5 is not a number of people that can attend her party. The number has to be a positive integer.
Usually, inequalities are graphed with shading up or down. In this case it is down because you have a limit on how much Gamora can spend.
The actual answer is 12 people.
Your answer was almost right if only you had converted it to the greatest positive integer less than 12.
Your graphing was wrong because you put 50 as the x intercept instead of the y intercept, and you forgot to shade. The question tells you to graph an inequality.
I hope this helps because I spent a long time typing this :)!

A cheese pizza at Chicago's Deep Dish pizza costs $7. Each topping costs an additional $0.75. A cheese pizza at Brooklyn's cost $12. Each topping costs an additional $0.50. Write an equation that represents how many toppings, y, must be added so that the two pizzas cost the same?
Step-by-step explanation:
Let the number of toppings be y
If cheese pizza at Chicago's Deep Dish pizza costs $7 and each topping costs an additional $0.75, the total amount of the dish pizza will be expressed as;
$7 + $0.75y ..... 1
Also, if a cheese pizza at Brooklyn's cost $12 and each topping costs an additional $0.50, then the total cost of cheese pizza will be;
$12 + $0.50y ........ 2
If the two pizzas cost the same, then equation 1 will be equal to equation 2 as shown;
7+0.75y = 12+0.50y
Make y the subject of the formula to generate the required equation for y:
0.75y-0.50y = 12-7
0.25y = 5
divide both sides by 0.25
0.25y/0.25 = 5/0.25
y = 5/0.25
y = 20
Hence the equation that represents how many toppings, y, must be added so that the two pizzas cost the same is y = 5/0.25 and the number of toppings added is 20.

Jaycie has 21 gallons of gas in her car and uses approximately .05 gallons of gas each mile that she drives. Which equation shows the linear relationship between x, the number of miles Jaycie has driven, and y, the total gallons of gas in her car? a. Y = 21x - .05 b. Y = -.05(x+21) c. Y = 21 - .05x d. Y =21 + .05x
Given:
Jaycie has 21 gallons of gas in her car and uses approximately .05 gallons of gas each mile that she drives.
To find:
The equation which shows the linear relationship between x, the number of miles Jaycie has driven, and y, the total gallons of gas in her car.
Solution:
We have,
Initial amount of gas in car = 21 gallons
So, y-intercept of the linear relationship is 21.
It uses approximately .05 gallons of gas each mile that she drives.
It means, the gas is decreased by .05 gallons for each mile.
So, slope of the linear relationship is -0.05. Here, negative sign represents the decrease in amount of gas.
Slope intercept form of a line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept or initial value.
Substitute m=-.05 and b=21 in the above equation.
[tex]y=-.05x+21[/tex]
[tex]y=21-.05x[/tex]
So, the equation [tex]y=21-.05x[/tex] represents the linear relationship between x, the number of miles Jaycie has driven, and y, the total gallons of gas in her car.
Therefore, the correct option is c.
y=-2x+4 y=6x+12 substitution method
Answer:
x = - 1, y = 6
Step-by-step explanation:
Given the 2 equations
y = - 2x + 4 → (1)
y = 6x + 12 → (2)
Substitute y = 6x + 12 into (1)
6x + 12 = - 2x + 4 ( add 2x to both sides )
8x + 12 = 4 ( subtract 12 from both sides )
8x = - 8 ( divide both sides by 8 )
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (2)
y = 6(- 1) + 12 = - 6 + 12 = 6
Solution is (- 1, 6 )
