f(x)=-x^2+8x-14 using quadratic formula
Answer:
Were you looking for the x and y intercepts? The question is very misleading.
If you were the x intercepts are (4-√2,0), (4+√2,0)
And the y intercept is (0,−14)
If you did not mean this in your question please specify what you meant.
Answer:
[tex]x=4-\sqrt{2}[/tex] or [tex]x=4+\sqrt{2}[/tex]
Step-by-step explanation:
Plug in given values of a, b, and c into the quadratic formula and solve for x:
[tex]x=\frac{-b±\sqrt{b^{2}-4ac } }{2a}[/tex]
[tex]x=\frac{-8±\sqrt{8^{2}-4(-1)(-14) } }{2(-1)}[/tex]
[tex]x=\frac{-8±\sqrt{64-56 } }{-2}[/tex]
[tex]x=\frac{-8±\sqrt{8} }{-2}[/tex]
[tex]x=\frac{-8±2\sqrt{2} }{-2}[/tex]
[tex]x=4±-\sqrt{2}[/tex]
Therefore, the roots are [tex]x=4-\sqrt{2}[/tex] or [tex]x=4+\sqrt{2}[/tex]
A blouse originally $29..99 is 15% off. Marlene has a coupon for an additional
20% percent off. What is the new price of the blouse before tax?
Answer:
20.39
Step-by-step explanation:
15% of 29.99 is 4.4985
so
29.99-4.5
=
25.49
subtract the 20%
20% of 25.49
=
5.1
lastly,
25.49-5.1
=
20.39

Your parents are planning to rent you an apartment when you go to college. The annual contract is $535.00/month with a 2-month penalty for breaking the lease. The month-to-month contract is $615.00/month. What is the difference in the amount paid if you leave after 8 months?
Answer:
The difference in amount = $430
Step-by-step explanation:
1- Annual contract:
The annual contract means a contract for 12 months. There is a month penalty for breaking the lease.
This means that, if you left after 8 months, you will have to pay for 10 month.
Total paid = monthly payment * 10
Total paid = 535 * 10 = $5350
2- Month-to-month contract:
You will only paid for the 8 months you stayed,
Total paid = monthly payment * 8
Total paid = 615 * 8 = $4920
3- Getting the difference:
We can note that a month-month contract is a better option if you intend to stay for only 8 months
Difference = 5350 - 4920 = $430
Hope this helps :)

An unknown number y is 15 more than an unknown number x. The number y is also x less than 8. The equations to find x and y are shown below.
y = x + 15
y = −x + 8
Which of the following statements is a correct step to find x and y?
and could somebody please give me a step by step explanation
Answer:
x = −3.5
y = 11.5
Step-by-step explanation:
y = x + 15
y = −x + 8
[We know that y is 15 units more than x, and that −x is 8 units less than y. That can be combined into −x + 8 = x + 15 for the first variable (x), and for the second variable (y), y − 15 = −y + 8]
↓
In order to solve this, solve for the first variable in one of the equations, then substitute the result into the other equation.
↓
x = −[tex]\frac{7}{2}[/tex] = −3.5
y = [tex]\frac{23}{2}[/tex] = 11.5

Also, three apples and six pears costs [tex]\$1.47[/tex]
Suppose [tex]x[/tex] and [tex]y[/tex] be the price of apple and pear. So, we can write the cost as

If f(x)= 9x^2+2x-3, find f(-1).
Answer:
f(-1)= 4
Step-by-step explanation:
Just plug -1 into all Xs
and split it into 2 seperate problems for the time being
[9 times (-1)^2] + [2(-1)-3]
-1 squared is positive 1 times the 9 is just 9
Plus 2 times -1 is -2 minus 3 is -5
combine the two seperate problems you have
9-5 the subtract and
f(-1)= 4
Given square ABCD, which line segment could be an image of side AD using only a translation?
Answer:
The second one
Step-by-step explanation:
Line segment BC will be an image of side AD using only a translation.
Option 2 is true.
What is Translation?
A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.
Given that;
A figure ABCD is a square.
Now,
Since, ABCD is a square.
So, All sides of square ABCD are equal to each other.
Since, A translation occurs when a figure is moved from one location to another location without changing its size or shape.
Thus, Line segment BC will be an image of side AD using only a translation.
Therefore, Line segment BC will be an image of side AD using only a translation.
