Which of the following represents a function?
Answer:
Hey there!
Choice A represents a function, because a function only has one y value for every x value.
Hope this helps :)
Answer:
A
Step-by-step explanation:
In a function, the x value can only go to one y value
B has x=5 going to y = 13 and y = 17
C had x = -3 with y values of 1 and -1
D has x = -4 going to y = 52 and 16
A each input has only one output value
Timmy writes the equation f(x) = f(x) equals StartFraction one-fourth EndFraction x minus 1.x – 1. He then doubles both of the terms on the right side to create the equation g(x) = g(x) equals StartFraction one-half EndFraction x minus 2.x – 2. How does the graph of g(x) compare to the graph of f(x)? The line of g(x) is steeper and has a higher y-intercept. The line of g(x) is less steep and has a lower y-intercept. The line of g(x) is steeper and has a lower y-intercept. The line of g(x) is less steep and has a higher y-intercept.
Answer:
the line of g(x) is steeper and has lower y intercept
Step-by-step explanation:
f(x)=1/4x-1
g(x)=1/2x-2
g(x) is steeper because the slope of gx is greater than f(x)
y intercept of gx=-2 and for f(x)=-1
the y intercept of g(x) is lower than the y intercept of f(x)
The steepness of a function is dependent on its slope.
The true statement is: (c) the line of g(x) is steeper and has lower y intercept
The equations are given as:
[tex]\mathbf{f(x)= \frac 14x-1}[/tex]
[tex]\mathbf{g(x)=\frac12x - 2}[/tex]
A linear function is represented as:
[tex]\mathbf{y = mx + b}[/tex]
Where:
m represents the slope/steepb represents the y-interceptFor f(x)
[tex]\mathbf{m_1 = \frac{1}4}\\\mathbf{b = -1}[/tex]
For g(x)
[tex]\mathbf{m_1 = \frac{1}2}\\\mathbf{b = -2}[/tex]
By comparison:
Steepness: 1/2 > 1/4y-intercept: -1 > -2This means that: the line of g(x) is steeper and has lower y intercept
Hence, the true option is: (c)

HELP SOMEONE PLEASE! SO CONFUSED
Answer: The area is 24 square units.
Step-by-step explanation:
Things you need to use in this exercise:
Area of a circle = pi*r^2
r is the radius, equal to half the diameter.
Ok, in the image we can see 3 half-circles.
one has a diameter of 8 units: with area A (the left one)
other has a diameter of 6 units: with area B (the bottom one)
and the other has a diameter equal to the hypotenuse of the right triangle: with area C (the white semicircle that also includes the right triangle)
Now, you can think the shaded area as:
The sum of the areas of the half circles A and B, minus the area of the half-circle C, plus the area of the right triangle (because the white triangle is also included in the white semicircle)
So the area is:
A + B - C + area triangle
A = pi*(8/2)^2 = 3.14*4^2 = 50.24
B = pi*(6/2)^2 = 3.14*3^2 = 28.26
the area of the triangle is equal to:
T = 6*8/2 = 24
Now, to obtain the area of the white semicircle ( C) we need the hypotenuse of the triangle, so here we can use the Pythagorean's theorem:
H^2 = 8^2 +6^2
H = √(8^2 + 6^2) = 10
Then:
C = pi*(10/2)^2 = 3.14*5^2 = 78.5
Then the shaded area is:
Area = 50.24 + 28.26 + 24 - 78.5 = 24

The ratio of the amount of vitamin A in cow milk to the amount of vitamin A in goat milk is 333 to 444. If a liter of cow milk has 156015601560 international units (\text{IU})(IU)left parenthesis, start text, I, U, end text, right parenthesis of vitamin A, how many \text{IU}IUstart text, I, U, end text of vitamin A are in a liter of goat milk?
Answer:
[tex]Goat = 2080IU[/tex]
Step-by-step explanation:
Given
Ratio = 3 : 4
Litre of cow = 1560IU
Required
IU of a litre of goat
The ratio represents ratio of cow milk to goat milk
In other words;
[tex]Cow:Goat = 3 : 4[/tex]
To calculate the number of IU in a litre of goat milk; we substitute Cow with 1650 in the above expression
[tex]Cow:Goat = 3 : 4[/tex]
[tex]1560:Goat = 3 : 4[/tex]
Convert to fraction
[tex]\frac{1560}{Goat} = \frac{3}{4}[/tex]
Multiply both sides by 4
[tex]4 * \frac{1560}{Goat} = \frac{3}{4} * 4[/tex]
[tex]\frac{4 * 1560}{Goat} = \frac{ 4 * 3}{4}[/tex]
[tex]\frac{6240}{Goat} = 3[/tex]
Multiply both sides by Goat
[tex]Goat * \frac{6240}{Goat} = 3 * Goat[/tex]
[tex]6240 = 3 * Goat[/tex]
Divide both sides by 3
[tex]\frac{6240}{3} = \frac{3 * Goat}{3}[/tex]
[tex]\frac{6240}{3} = \frac{3 * Goat}{3}[/tex]
[tex]2080 = Goat[/tex]
[tex]Goat = 2080[/tex]

Together, Dante and Mia have a total of 350 pennies in their piggy banks. After Dante lost ½ of his pennies and Mia lost ⅓ of her pennies, they both had an equal number of pennies. Altogether, how many pennies did they lose?
Answer:
Altogether they lost 150 pennies.
Step-by-step explanation:
X = Dante's pennies
Y = Mia's pennies
X + Y = 350 1/2 X = 2/3 Y
X = 4/3 Y
4/3 Y + Y = 350
7/3 Y = 350
Y = 350 * 3/7
Y = 50 * 3
Y = 150
X + 150 = 350
X = 200
1/2 * 200 = 2/3 * 150
100 . = 100
1/2 * 200 = 100 -> Dante lost 100 pennies
1/3 * 150 = 50 -> Mia lost 50 pennies
Altogether they lost 150 pennies.

Two consecutive odd whole numbers are selected. The difference between the reciprocals of the two numbers is 2/143. Determine the two numbers.
Answer:
The numbers are 11 and 13
Step-by-step explanation:
Let
the first odd whole number=x
Reciprocal=1/x
Second odd whole number=x+2
Reciprocal=1/x+2
The difference
(1/x) - 1/(x+2)=2/143
(x+2)-x / (x)(x+2)=2/143
x+2-x/x(x+2)=2/143
2/x(x+2)=2/143
2(143)=2(x^2+2x)
286=2x^2+4x
2x^2+4x-286=0
x^2+2x-143=0
Solve the quadratic Equation
x=-b +or- √b^2-4ac/2a
a=1
b=2
c=-143
x= -b +or- √b^2-4ac/2a
=-2 +or- √(2)^2-(4)(1)(-143) / 2(1)
= -2 +or- √4-(-572) / 2
= -2 +or- √4+572/2
= -2 +or- √576/2
= -2 +or- 24/2
x= -2+24/2
= 22/2
=11
Or
x= -2-24/2
= -26/2
= -13
Taking the positive value
x=11
The second odd whole number=x+2
=11+2
=13

Which is equivalent equation solved for h?
Answer:
The answer is option A.
p = 0.7(rh + b)
Making h the subject
divide both sides by 0.7
we get
p/0.7 = rh + b
send b to the left side of the equation
p / 0.7 - b = rh
divide both sides by r
we get
( p / 0.7 - b) ÷ r = h
therefore h = ( p / 0.7 - b ) ÷ r

Answer:
Height = 3cm
Volume = 50.27cm^3
Step-by-step explanation:
Well to solve for the height with slant height and radius we can use the Pythagorean Theorem,
Which is [tex]a^2 + b^2 = c^2[/tex].
So we have c and a, so we have to fill those in.
(4)^2 + b^2 = (5)^2
16 + b^2 = 25
-16
b^2 = 9
[tex]\sqrt{b} \sqrt{9}[/tex]
b = 3cm
So to find the volume of a cone we use the following formula [tex]\pi r^2 \frac{h}{3}[/tex].
So we have the radius and height so we just fill those in.
(pi)(4)^2(3)/3
(pi)16(1)
pi*16

Answer:
-7 ± i√127
x = -----------------
2
Step-by-step explanation:
Next time, please share the possible answers. Thank you.
x^2 + 7x + 44 has a parabolic graph that opens up and never intersects the x-axis. Thus, it has no real roots.
The coefficients of this polynomial are a = 1, b = 7, c = 44.
The discriminant is b^2 - 4ac, or 7^2 - 4(1)(44) = -127. As expected, this is negative, confirming that the roots are complex.
The roots are:
-7 ± i√127

Answer:
x =- 3 and y = -7
Step-by-step explanation:
2X-2Y=-8
X=2y + 11
We need to isolate both X and Y in both equations
so
2x-2y=-8
(add 2y to both sides)
2x=-8+ 2y
(divide both sides by 2)
x=-4+y and x=2y+11
because both of these equations are the same we can put them together
4+y=2y+11
(subtract y)
4=y+11
(subtract 11)
-7=y
so y = -7
then to find x you just need to plug in y to one of the equations
x=2(-7) + 11
x= -14 +11
x = -3
Answer:
x = - 19, y = - 15
Step-by-step explanation:
Given the 2 equations
2x - 2y = - 8 → (1)
x = 2y + 11 → (2)
Substitute x = 2y + 11 into (1)
2(2y + 11) - 2y = - 8 ← distribute and simplify left side
4y + 22 - 2y = - 8
2y + 22 = - 8 ( subtract 22 from both sides )
2y = - 30 ( divide both sides by 2 )
y = - 15
Substitute y = - 15 into (2) for corresponding value of x
x = 2(- 15) + 11 = - 30 + 11 = - 19
Solution is x = - 19, y = - 15
