Answer:
Step-by-step explanation:Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola.
The vertex of a parabola is the point at the top or bottom of the parabola.
'h' is -6, the first coordinate in the vertex.
'k' is -4, the second coordinate in the vertex.
'x' is -2, the first coordinate in the other point.
During the annual black Friday sale,the OLX sold a price of ski boots at regular price of $245 at a discount of 40%the boots cost 96$, and expenses at 26% of the regular price, how much was the ski boots sold
Answer: $147
Step-by-step explanation:
The boots were sold at a 40% discount of the regular price of $245.
The price they were sold at is therefore:
= Price * ( 1 - discount)
= 245 * ( 1 - 40%)
= 245 * 60%
= $147

What is the expansion of square of sum of two terms?Suppose that two terms are 'a' and 'b'.
Then, their sum's square is expanded as:
[tex](a+b)^2 = a^2 + 2ab + b^2[/tex]
For this case, we're given the quadratic equation with its 4 steps of solution as:
[tex]ax^2 + bx + c = 0\\\\\dfrac{ax^2}{a} + \dfrac{bx}{a} + \dfrac{c}{a} = 0\\\\x^2 + \dfrac{bx}{a} + \dfrac{c}{a} = 0\\\\x^2 + \dfrac{bx}{a} = -\dfrac{c}{a}\\\\x^2 + \dfrac{bx}{a} + \dfrac{b^2}{4a^2} = -\dfrac{c}{a} + \dfrac{b^2}{4a^2}[/tex]
We've to proceed to the next step.
In the left hand side, we can use the formula [tex](a+b)^2 = a^2 + 2ab + b^2[/tex], where [tex]\rm a \: is \: x^2, and \: b \: is \: \dfrac{b}{2a}[/tex]
Thus, we have:
[tex]x^2 + \dfrac{bx}{a} + \dfrac{b^2}{4a^2} = x^2 + 2 \times x \times \dfrac{b}{2a} + \left(\dfrac{b}{2a} \right)^2 = \left( x + \dfrac{b}{2a} \right)^2[/tex]
We expressed the left sided expression in this form so that the variable 'x' (which is assuminly the only variable in the equation, whose value is to be known) gets packed into single container and not spread throughout with different powers.
Now, we can use square root and then subtraction and division of some terms which will make 'x' stay on one side of the equation, and rest of the constants on other side, as the value of 'x' for which the considered equation [tex]ax^2 + bx + c = 0[/tex] is correct.
The next step of the solution, therefore, is:
[tex]\left( x + \dfrac{b}{2a} \right)^2 = \dfrac{-c}{a} + \dfrac{b^2}{4a^2}[/tex]

B
Step-by-step explanation:
Hey There!
They are asking for the slope in standard form
y = mx + b
where m equals slope and b equals y intercept
the y intercept is located at point (0,-8) so b = -8
the slope is change in y over change in x
as y goes up one x goes up 1
1/1 = 1 so the slope is just x
so we can conclude that the equation is y = x - 8

Using t and c as variables, we get
100c + 400t ≥ 5400
Simplified,
100(c + 4t) ≥ 5400
c + 4t ≥ 54
To find the minimum number of chairs that need to be sold, we evaluate using t = 0
c + 4(0) ≥ 54
c ≥ 54
To find the minimum number of tables that need to be sold, we evaluate using c = 0
(0) + 4t ≥ 54
4t ≥ 54
t ≥ 13.5 Since we can't purchase half a chair, we round up our result giving us t ≥ 14

Answer:
a) The addition property of equality
b) The division property of equality
Step-by-step explanation:
Here, we want to know the correct step to use
From the given question, to proceed;
All we have to do is to move the value that has a negative value on the left hand side to the right hand side
what accompanies this is the addition of the both terms, on the right hand side
After this, we now proceed to divide the sum by the coefficient of x
Thus, the correct choices are;
a) The addition property of equality
b) The division property of equality

"The Martin family's truck gets an average of 25 miles per gallon of fuel. Predict how many miles they will be able to get from 7 gallons of fuel by using equivalent rates." (Explain with fractions/ equivalent rate in detail pls)
Answer:
175 miles
Step-by-step explanation:
Average of 25 miles per gallon of fuel
Miles : gallons = 25 : 1
Predict how many miles they will be able to get from 7 gallons of fuel by using equivalent rates
Let x = number miles
Miles : gallons = x : 7
To find x
25 : 1 = x : 7
25/1 = x/7
Cross product
25*7 = 1*x
175 = x
x = 175 miles
Number miles = 175
