Determine which equation has exactly one real solution. PLS HELPP
Answer:
b) [tex]4x^2-12x+9=0[/tex]
Step-by-step explanation:
We can use the discriminant [tex]b^2-4ac[/tex] to determine how many real solutions a quadratic equation in the form [tex]ax^2+bx+c=0[/tex] has.
discriminant > 0 ⇒ 2 real solutionsdiscriminant = 0 ⇒ 1 real solutiondiscriminant < 0 ⇒ no real solutions[tex]5x^2+9x-4=0[/tex]
[tex]b^2-4ac=9^2-4(5)(-4)=161 > 0\implies \textsf{2 solutions}[/tex]
[tex]4x^2-12x+9=0[/tex]
[tex]b^2-4ac=(-12)^2-4(4)(9)=0 \implies \textsf{1 solution}[/tex]
[tex]-9x^2+6x+1=0[/tex]
[tex]b^2-4ac=6^2-4(-9)(1)=72 > 0 \implies \textsf{2 solutions}[/tex]
[tex]-2x^2-7=0[/tex]
[tex]b^2-4ac=0^2-4(-2)(-7)=-56 < 0 \implies \textsf{no solutions}[/tex]
Carlos rented a truck for one day. There was a base fee of $19.99, and there was an additional charge of 86 cents for each mile driven. Carlos had to pay $201.45 when he returned the truck. For how many miles did he drive the truck?
Answer: 211 miles
Step-by-step explanation: An equation for this could be:
base fee + additional charge (miles driven) = total charge
19.99 + 0.86(x) = 201.45
0.86(x) = 201.45 - 19.99
0.86(x) = 181.46
x = [tex]\frac{181.46}{0.86}[/tex] = 211 miles
The wholesale price for a bookcase is $105. A certain furniture store marks up the wholesale price by 28% Find the price of the bookcase in the furniture store.
Round your answer to the nearest cent, as necessary.
Answer:
$134.40
Step-by-step explanation:
The markup is 28% of 105, or .28(105) = $29.40
Thus the retail price is $105 + $29.40 = $134.40
The price of the bookcase in the furniture store, after a 28% markup on the wholesale price, is $134.40.
To find the price of the bookcase in the furniture store after a 28% markup on the wholesale price, we need to add the markup amount to the wholesale price.
The markup amount is calculated by multiplying the wholesale price by the markup percentage (expressed as a decimal). In this case, the markup percentage is 28%, which is equivalent to 0.28 as a decimal.
Markup amount = Wholesale price * Markup percentage
Markup amount = $105 * 0.28
Markup amount = $29.40
Now, to find the price of the bookcase in the furniture store, we add the markup amount to the wholesale price:
Price in the furniture store = Wholesale price + Markup amount
Price in the furniture store = $105 + $29.40
Price in the furniture store = $134.40

Answer:
4680 dollars
Step-by-step explanation:
Hello, I'd love to help you!
We know that:
-Original price is 7200 dollars
-Manuel only paid for 65% of it
-> think of it this way: think of the overall price as a pie; Manuel only ate 65% of it
To calculate how much Manuel paid, we can multiply 7200 times 0.65 (percentage in decimal form), which equals 4680 dollars.

Select the correct answer from each drop-down menu. Polygon ABCD goes through a sequence of rigid transformations to form polygon A′B′C′D′. The sequence of transformations involved is a reflection across the , followed by a reflection across the line . Reset Next
Answer:
The sequence of transformations involved is a reflection across the x axis, followed by a reflection across the y = x line
Step-by-step explanation:
The polygon ABCD is shown in the image attached. The coordinates of the polygon are A(-6, 6), B(-4, 6), C(-4, 4), D(-6, 2), while the polygon A'B'C'D' is at A'(-6, -6), B'(-6, -4), C'(-4, -4), D'(-2, -6)
A transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, dilation and rotation.
If a point O(x, y) is reflected across the x axis, the new coordinate is O'(x, -y).
If a point O(x, y) is reflected across the y = x line, the new coordinate is O'(y, x)
Hence if polygon ABCD is reflected across the x axis, the new coordinates are A*(-6, -6), B*(-4, -6), C*(-4, -4), D*(-6, -2). If a reflection across the y = x line, the new coordinates are A'(-6, -6), B'(-6, -4), C'(-4, -4), D'(-2, -6)
Answer:
Polygon ABCD goes through a sequence of rigid transformations to form polygon A′B′C′D′. The sequence of transformations involved is a reflection across the y-axisy = -x, followed by a reflection across the line y = xy = -x.

Answer:
4 Hours and 32 minutes
Step-by-step explanation:
Let's first find the amount between 9:15 to 2:17
The difference between 9:00 and 2: 00 is 5 Hours
Now the minutes -> 17-15 = 2
Thus, the difference is 5 Hour and 2 Minutes
Then She took a 30 minutes break for lunch.
Let's convent all to minutes:
1 Hour = 60
Then 60 x 5 = 300
Plus the 2 minutes is
302
Now 302 minutes - 30 minutes = 272 minutes
Now convent back to Hour
Thus, 272/60 =4 with a remainder of 32.
Hence, it took stephanie 4 hour and 32 minutes to finish her SOL test.

Solve the system using elimination.
X + 7y = 25
2x - 7y = -13
Answer:
[tex](4;3)[/tex]
Step-by-step explanation:
Add the two equations together
[tex]I+II: x+7y+2x-7y=25-13 \rightarrow 3x=12\rightarrow x =4[/tex]
At this point i'd rather replace x=4 in the first equation to get [tex]4+7y=25 \rightarrow 7y=21 \rightarrow y=3[/tex]
To keep eliminating you multiply the first by 2 and subtract the second
[tex]2\times I -II: 2x+14y-2x-(-7y)=50-(-13)\rightarrow 21y=63 \rightarrow y=3[/tex]
