NEED HELP ASAP!! which function has a range of y is greater than or equal to 0
Answer:
c
Step-by-step explanation:
The third function has a range of y that is greater than or equal to 0.
What is a function?A function is a kind of rule that, for one input, gives you one output.
For the first function, it contains negative values for y, so it was eliminated.
The second function did not start from zero, so it was eliminated.
The third function obeys the given condition, but the last function contains negative values for y.
Hence, the third function satisfies the condition that y is greater than or equal to 0.

Solve for x
5x – 2(x+1)= 1/4
Enter your answer as a fraction in simplest form in the box.
X =
Basic
Answer:
x = 3/4
Step-by-step explanation:
Step 1: Write equation
5x - 2(x + 1) = 1/4
Step 2: Solve for x
Distribute -2: 5x - 2x - 2 = 1/4Combine like terms: 3x - 2 = 1/4Add 2 to both sides: 3x = 9/4Divide both sides by 3: x = 3/4Step 3: Check
Plug in x to verify it's a solution.
5(3/4) - 2(3/4 + 1) = 1/4
15/4 - 2(7/4) = 1/4
15/4 - 14/4 = 1/4
1/4 = 1/4

Step-by-step explanation:
If [tex]\sf x^{(x^4)} = 4,[/tex] then find the value of [tex]\sf x^{(x^2)} + x^{(x^8)}.[/tex]
By inspection, we can see that x = ±√2, since (±√2)⁴ = 2² = 4.
In particular, if [tex]x^n=n[/tex], which means [tex]x=n^{\frac1n}[/tex], then [tex]x^{x^n}=x^n=n[/tex].
Let x = √2. Then
[tex]x^{x^2}+x^{x^8}=(\sqrt2)^{(\sqrt2)^2}+(\sqrt2)^{(\sqrt2)^8}[/tex]
[tex]x^{x^2}+x^{x^8}=(\sqrt2)^2+(\sqrt2)^{16}[/tex]
[tex]x^{x^2}+x^{x^8}=2+256[/tex]
[tex]x^{x^2}+x^{x^8}=\boxed{258}[/tex]
3. f(x) = x2 + 4x - 2
Answer:
f(x)= -(x-2)^2+2
Step-by-step explanation:
the same valuve needs the be added to both sides
f(x)+?= -x^2+4x+?-2
to complete the square -x^2+4x-4= -(x-2)^2 add the -4 to the expression
f(x)+?= -x^2+4x-4-2
since -4 was added to the right side, also add -4 the the left side
f(x)-4= -x^2+4x+?-2
now factor out the negative sign from the expression
f(x)-4= -(x^2-4x+4)-2
using a^2-ab+b^2=(a-b)^2
f(x)-4= -(x-2)^2-2
move the constant the the right side and change its sign
f(x)= -(x-2)^2-2+4
now calculate the sum
f(x)= -(x-2)^2+2

Karen finished 4.367 seconds ahead of Mary.
Brenda finished in 35.04 seconds.
Brenda finished 2.45 seconds behind Mary.
What was Karen’s finish time?
Answer:
33.123
Step-by-step explanation:
Brenda is at 35.04 seconds which is 2.45 seconds behind Mary so Mary is at 37.49 seconds.
Karen is ahead of Mary by 4.367 seconds which means she is at 33.123
The width of a classroom is 4 meters less than the length, and the area is 192 m^2. If the length is x m, find an equation in x and hence, find the dimensions of the classroom.
Answer:
length-x
width-x-4
area-- length* width
192=X*(X-4)
x^2-4x-192=0
x^2-16x+12x-192=0
X(x-16)+12(x-16)=0
(x-16),(X+12)
X= 16 because X cannot be negative like (-12)
the dimensions of the classroom will be
length = 16
width = 12

Which equation represents a line with a slope of zero?
O y= 2x
O y=-3x+
O y=4
O x=-5
Answer:
y = 4
Step-by-step explanation:
In y =mx+b (slope -intercept form ),
We have m to be the slope
The first and the second equations contains the slope (coefficient of x)
The fourth option clearly states the slope is -5
That leaves with the third option with only a y-intercept.
Answer:
y=4
Step-by-step explanation:
y=4 on the graph would look like this -------------------------- and it would have a slope of zero. It's not x = -5 because that would have an undefined slope |.
And the first two the slope is the number in front of the x.

the square with a side length (x + 3) and an equilateral triangle with side lengths (3x-1) have the same perimeter what is the value of x?
Help please
Answer:
x = 3
Step-by-step explanation:
Side lenght of square = (x + 3)
Side length of equilateral triangle = (3x - 1)
It is Given that:
Perimeter of square = Perimeter of equilateral triangle
4 times side length of square = 3 times side length of equilateral triangle.
[tex] \therefore \: 4(x + 3) = 3(3x - 1) \\ \\ \therefore \: 4x + 12 = 9x - 3 \\ \\ \therefore \:12 + 3 = 9x - 4x \\ \\ \therefore \:15 = 5x \\ \\ \therefore \:x = \frac{15}{5} \\ \\ \huge \red{ \boxed{\therefore \:x = 3}}[/tex]

If m∠7 = 55°, which of the following statements are true? Select all that apply. There are two horizontal parallel lines are cut by a transversal. The top left angle is denoted by 1 when transversal line makes an angle with upper horizontal line. The supplementary angle of angle 1 (which is top right angle) is denoted by 2 and opposite angle is denoted by 4. The remaining angle is denoted by 3. The corresponding angle of 1 is denoted by 5 and the corresponding angle of 2 is denoted by 6. The opposite angle of 5 is denoted by 8 and opposite angle of 6 denoted by 7. A. m∠6 = 55° B. m∠5 = 135° C. m∠1 + m∠4 = 250° D. m∠1 + m∠6 = m∠7 + m∠4
Answer:
The true statements are;
A. m∠6 = 55°
C. m∠1 + m∠4 = 250°
D. m∠1 + m∠6 = m∠7 + m∠4
Step-by-step explanation:
The given information are;
m∠7 = 55°
The angles formed by the transversal and the upper horizontal parallel line are (starting from the top left and moving in clockwise direction) = 1, 2, 4, 3
Similarly, the angles formed by the transversal and the lower horizontal parallel line are (starting from the top left and moving in clockwise direction) = 5, 6, 8, 7
Therefore, we have;
m∠7 ≅ m∠6 (Vertically opposite angles are congruent)
∴ m∠6 = m∠7 = 55°
m∠6 = 55° which corresponds with option A.
m∠5 + m∠6 = 180° (The sum of angles on a straight line)
∴ m∠5 = 180° - m∠6 = 180° - 55° = 125°
m∠5 = 125°
m∠1 ≅ m∠5 (Corresponding angles)
∴ m∠1 = m∠5 = 125°
m∠1 ≅ m∠4 (Vertically opposite angles)
∴ m∠1 = m∠4 = 125°
∴ m∠1 + m∠4 = 125° + 125° = 250°
m∠1 + m∠4 = 250° which corresponds with option C.
m∠1 ≅ m∠4 (Vertically opposite angles)
m∠6 ≅ m∠7 (Vertically opposite angles)
∴ m∠1 + m∠6 = m∠7 + m∠4 (Transitive property) which corresponds with option D.
