What number is the opposite of 0.93?
Answer:
I'm not sure what you mean by opposite, but by all means the opposite of 0.93 would be -0.93 as it's the negative value of that decimal.
Step-by-step explanation:
Which is an equation of the.line with a slope of 1/4 and a y-intercept if -2?
A. x-4y=8
B. x+4y=-8
C. 4x+y=-2
D. 4x-y=2
Answer:
A. x-4y=8
Step-by-step explanation:
Slope = [tex]\frac{1}{4}[/tex]
y-intercept = -2
In y=mx+b
m = slope
b = y-intercept
Just replace m with 1/4 and b with -2
[tex]y = \frac{1}{4} x -2\\[/tex]
Multiply through by 4 and re-arrange
[tex]4(y=\frac{1}{4} x -2)\\\\4y =x -8\\0 =-4y +x-8\\8 =-4y+x\\\\x -4y =8[/tex]

What is the standard form for a quadratic equation? _______________________________ What is the vertex form of a quadratic equation? __________________________________ What is the factored form of a quadratic equation
Answer:
I believe the standard form is: ax2+bc+c=0
Vertex form is:f(x)=a(x-h)2+k
Factored form is: y=1/2(x-6)(x+2)
Step-by-step explanation:
The ax2= ax squared and the (x-h)2= (x-h) squared

If one side of a square measures (3x − 8) ft. , find the area of the square. Show work.
Answer:
[tex]\huge\boxed{A=(9x^2-48x+64)ft^2}[/tex]
Step-by-step explanation:
The formula of an area of a square:
[tex]A=s^2[/tex]
[tex]s[/tex] - side of a square
We have [tex]s=(3x-8)ft[/tex]
Substitute:
[tex]A=(3x-8)^2[/tex]
METHOD 1:
Use [tex](a-b)^2=a^2-2ab+b^2[/tex]
[tex]A=(3x)^2-2(3x)(8)+8^2=9x^2-48x+64[/tex]
METHOD 2:
Use FOIL: [tex](a+b)(c+d)=ac+ad+bc+bd[/tex]
[tex]A=(3x-8)(3x-8)=(3x)(3x)+(3x)(-8)+(-8)(3x)+(-8)(-8)\\\\=9x^2-24x-24x+64=9x^2-48x+64[/tex]
Answer:
9x^2-48x+64 ft^2
Step-by-step explanation:
(3x − 8) (3x − 8)
Multiply 3x by (3x − 8)
3x(3x − 8)
9x^2-24x
Multiply - 8 by (3x − 8)
- 8(3x − 8)=-24x+64
Combine 9x^2-24x and -24x+64
9x^2-48x+64 ft^2

The length of a rectangle is six times its width. If the perimeter of the rectangle is 140 yd, find its length and width.
Answer:
[tex] \boxed{ \sf{length \: of \: a \: rectangle = 60 \: yd}}[/tex]
[tex] \boxed{ \sf{width \: of \: a \: rectangle = 10 \: yd}}[/tex]
Step-by-step explanation:
Let the width of a rectangle be 'w'
Length of a rectangle ( l ) = 6w
Perimeter of a rectangle ( P ) = 140 yd
Finding the width of a rectangle
[tex] \boxed{ \sf{perimeter \: of \: rectangle= 2(length + breadth)}}[/tex]
[tex] \dashrightarrow{ \sf{140 = 2(6w + w)}}[/tex]
[tex] \dashrightarrow{ \sf{140 = 2 \times 7w}}[/tex]
[tex] \dashrightarrow{ \sf{140 = 14w}}[/tex]
[tex] \dashrightarrow{ \sf{14w = 140}}[/tex]
[tex] \dashrightarrow{ \sf{ \frac{14w}{14} = \frac{140}{14}}} [/tex]
[tex] \dashrightarrow{ \sf{w = 10}}[/tex]
Width of a rectangle = 10 yd
Now, replacing / substituting the value of w in 6w in order to find the length of a rectangle
[tex] \dashrightarrow{ \sf{length = 6 \times x = 6 \times 10 = 60 \: yd}}[/tex]
Length of a rectangle = 60 yd
Hope I helped!

Answer:
14 books
Step-by-step explanation:
Let b = number of books at the beginning
She sold 1/2 of the books
b - 1/2 b
This is how many she had left
Then she bought 7
b - 1/2 b + 7
this equals 14
b - 1/2 b + 7 = 14
Combine like terms
1/2 b + 7 = 14
Subtract 7 from each side
1/2 b = 14-7
1/2 b = 7
Multiply each side by 2
1/2 b * 2 = 7*2
b = 14
She started with 14 books
in the nature of the roots, what if the answer is negative what will be it's root?
a.rational and unequal
b.irrational and unequal
c.rational and equal
d.imaginary and unequal
please needed the answer right away......
Answer:
d.imaginary and unequal
Step-by-step explanation:
In an effort to address this problem, mathematicians "created" a new number, i, which was referred to as an "imaginary number", since it was not in the set of "Real Numbers". This new number was viewed with much skepticism. The imaginary number first appeared in print in the year 1545
The imaginary number "i" is the square root of negative one.
neg i
An imaginary number possesses the unique property that when squared, the result is negative.

Is 9.52 less than 90.13?
Answer:
Yes, 9.52 is less than 90.13
Step-by-step explanation:
Because 90 is a whole number from the decimal 90.13, and 9 is the whole number from the decimal 9.52
Compare 90 and 9. 90 is greater; therefore, 9.52 is less than 90.13
Antonio has 150 baseball cards. He decided to give you 32% of his cards to you. How many cards did he give you?
Answer:
He gave you 48 cards.
Step-by-step explanation:
150 * 32% (which is also 0.32) is equal to 48.
Divide the percentage by 100.
32 / 100 = 0.32.
You then multiply 0.32 by 150 to get the part.
0.32 x 150 = 48.
32% of 150 is 48.
Your answer is 48 cards.

What two integers have the product of 28 and the sum of -11 ? a -2 and -14 b 4 and 7 c -4 and -7 d 2 and 14
Hey there! I'm happy to help!
Let's look at the factors of 28.
1,28
2,14
4,7
We see that 4 and 7 add to make 11, but not -11. Well, we can just make both of them negative and then it will be -11 and their product will still be 28. Our numbers are -4 and -7.

What is the length of BC in the right triangle below?
A. ^234
B. 234
c. ^216
D. 216
We can use the pythagorean theorem to solve this
The pythagorean theorem = a^2 + b^2 = c^2, while
a = one leg
b = the second leg
c = the hypotenuse
In this problem,
a = 3
b = 15
c = ?
Let's plug our values into the pythagorean theorem
(3)^2 + (15)^2 = c^2
9 + 225 = c^2
Add together the left side
234 = c^2
Take the sqrt of both sides
sqrt(234) = c
The length of BC = sqrt(234)

Apples at the grocery store cost $0.94
Apples at the grocery store costs $0.94 per pound. What is the total cost if Ashley
buys 3.25 pounds of apples? Round to the
nearest hundredth.
Answer:
$3.05 i'm pretty sure
Step-by-step explanation:
If one pound is $0.94 and she bought 3.25 pounds you multiply 3 by 0.94 and get $2.82 (we multiply by 3 to make it easier and to deal with the .25 later) then now we deal with the .25, since .25 is 1/4 in fraction just find out what 1/4 of .94 is which is .23 cents. So add $2.82 and $0.23 and you get $3.05
