Answer:
B
Step-by-step explanation:
Answer:
Step-by-step explanation:
So it seems you were able to eliminate a and c. Good job. :)
y= x/2 is the same as y= 1/2 * x + 0 (this is now in the form y= mx +b.)
y= x+ 2 is already in (y=mx+b) form, with m being 1.
now what you can do is look at the individual parts of these equations.
the b is the y intercept. So when x is 0, y is b. in the y= 1/2 x + 0 equation, we know when x= 0, y= 0.
for the y=x + 2, we know that when x= 0, y= 2. Since this is not a point on the line shown, we know that it is not correct. Therefore, your answer would be y= 1/2 x, or y= x/2.
You could also find this using slope, but the y- intercept (b) was simpler to explain and find. :)

The length of a rectangle is eight more than twice the width. The perimeter is 64. Find the length and width
Answer:
24 and 8
Step-by-step explanation:
The formula for the perimeter of the rect. is P = 2W + 2L.
Here, L = 2W + 8, so the area formula becomes:
P = 2W + 2(2W + 8) = 64
Dividing all terms by 2 reduces this to:
W + 2W + 8 = 32, or 3W = 24, or W = 8.
Then: L = 2W + 8 = 2(8) + 8 = 24
Check: does 2W + 2L = 64 when these values for W and L are substituted?
Is 2(8) + 2(24) = 64 true? Yes
The length and width are 24 and 8 respectively.
The length of rectangle will be 8 units.
The width of rectangle will be 24 units.
What is mean by Rectangle?
A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The length of a rectangle is eight more than twice the width.
The perimeter is 64.
Now,
Let the width of rectangle = x
Then, The length of rectangle = 2x + 8
Here, The perimeter is 64.
So, We get;
2 (length + width) = 64
2 (2x + 8 + x) = 64
2 (3x + 8) = 64
3x + 8 = 64/2
3x + 8 = 32
3x = 32 - 8
3x = 24
x = 8
Thus, The width of rectangle = x
= 8
Then, The length of rectangle = 2x + 8
= 2 × 8 + 8
= 24
Therefore, The length of rectangle will be 8 units.
The width of rectangle will be 24 units.

ANSWER
Converges
[tex]S_{ \infty } = 68[/tex]
EXPLANATION
The guy sequence is
17 + 12.75 + 9.5625 + ...
The common ratio is:
[tex] \frac{9.5625}{12.75} = \frac{12.75}{17} = \frac{3}{4} = r[/tex]
Since
[tex] |r| < 1[/tex]
the series converges.
The sum to infinity of this sequence is :
[tex]S_{ \infty } = \frac{a}{1 - r} [/tex]
where a=17 is the first term of the series.
[tex]S_{ \infty } = \frac{17}{1 - \frac{3}{4} } [/tex]
[tex]S_{ \infty } = \frac{17}{ \frac{1}{4} } = 68[/tex]

What is the equation of the line that passes through the point (-5, 2) and has an undefined slope?
Answer:
x = - 5
Step-by-step explanation:
A line with an undefined slope indicates that the line is vertical and parallel to the y- axis.
The equation of a vertical line is
x = c where c is the value of the x- coordinates the line passes through.
The line passes through (- 5, 2) with x- coordinate -5, hence
x = - 5 ← equation of line
The equation of a line that passes through the point (-5, 2) and has an undefined slope is x = -5.
i.e y-axis.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
We have,
The equation of a line passes through the point (-5, 2)
The equation of a line has an undefined slope.
Now,
An undefined slope means,
The line is parallel to the y-axis.
There is only one point on the x-axis.
Slope = Change in y-axis / Change in the x-axis
Slope= Change in y-axis / 0
Slope = undefined
If the slope of a line is undefined there is no y-intercept.
The equation of the line is:
y = mx + c
y = (1/0)x + 0
0 = x
x = 0
This means the y-axis.
The equation of the line passes through the point (-5, 2) so,
x = -5
Thus,
The equation of a line that passes through the point (-5, 2) and has an undefined slope is x = -5.

Let f(x) = 1/x and g(x) = x^2 + 4x. What
two numbers are not in the domain of fºg?
Answer:
0 and -4
Step-by-step explanation:
We have been given the following functions;
f(x) = 1/x
g(x) = x^2 + 4x
The first step would be to evaluate the composite function fºg.
fºg = f[g(x)]. We substitute g(x) in place of x in f(x)
fºg = [tex]\frac{1}{g(x)}=\frac{1}{x^{2}+4x}[/tex]
This is clearly a rational function which will be defined everywhere except where the expression in the denominator will be equal to 0.
We solve for x;
[tex]x^{2}+4x=0\\\\x(x+4)=0\\x=0\\x=-4[/tex]
Therefore, the two numbers that are not in the domain of fºg are 0 and -4
For this case we have the following equations:
[tex]f (x) = \frac {1} {x}\\g (x) = x ^ 2 + 4x[/tex]
We must find (f_ {o} g) (x):
By definition of composition of functions we have to:
[tex](f_ {o} g) (x) = f (g (x))[/tex]
So:
[tex](f_ {o} g) (x) = \frac {1} {x ^ 2 + 4x}[/tex]
We must find the domain of [tex]f (g (x)).[/tex] The domain will be given by the values for which the function is defined, that is, when the denominator is nonzero.
[tex]x ^ 2 + 4x = 0\\x (x + 4) = 0[/tex]
So, the roots are:
[tex]x_ {1} = 0\\x_ {2} = - 4[/tex]
The domain is given by all real numbers except 0 and -4

Answer:
x = 4, y = 2
Step-by-step explanation:
Given the 2 equations
5x + 2y = 24 → (1)
5y = x + 6 → (2)
Rearrange (2) expressing x in terms of y by subtracting 6 from both sides
x = 5y - 6 → (3)
Substitute x = 5y - 6 into (1)
5(5y - 6) + 2y = 24 ← distribute and simplify left side
25y - 30 + 2y = 24
27y - 30 = 24 ( add 30 to both sides )
27y = 54 ( divide both sides by 27 )
y = 2
Substitute y = 2 into (3) for corresponding value of x
x = (5 × 2) - 6 = 10 - 6 = 4

Answer:
36
Step-by-step explanation:
This figure is a trapeoid.
Turning the figure sideways,
A = 1/2 (b1+b2) *h where b1 and b2 are the top and bottom and h is the height
b1 and b2 are the top and bottom so b1 =6 and b2=12 and h is the height so h = 4
A = 1/2 (6+12)*4
A = 1/2 (18)*4
= 9*4
= 36 in^2
The area of the irregular figure is 36 sq. in.
Given is an irregular figure with dimensions 6 in, 4 in and 12 in, we need to find the area of the irregular figure,
To find the area of the given figure, we will break the figure into two regular figures,
a) Triangle [base = 4 in and height = 12-6 = 6 in]
b) Parallelogram [base = 4 in and height = 6 in]
Area of a triangle = 1/2 × base × height
Area of a parallelogram = base × height
Therefore,
Area of the irregular figure = [1/2 × 4 × 12] + 4 × 6
= 24 + 12
= 36
Hence the area of the given figure is 36 in².

The volume of a cube is 729 cubic feet . What is the side length of the cube ?
Side length of cube = 9 feet
The side length of the cube is 9 feet. Thus, the third option is correct.
To find the side length of a cube when given its volume, we can use the formula for the volume of a cube:
Volume = side length³
In this case, we know that the volume of the cube is 729 cubic feet.
Let's substitute this value into the formula:
729 = side length³
To find the side length, we need to take the cube root of both sides of the equation:
∛729 = ∛(side length³)
Simplifying:
9 = side length
Therefore, the side length of the cube is 9 feet.

An opaque bag contains 5 green marbles 3 blue marbles and 2 red marbles. what is the of randomly picking out a marble and the marble being red?
Answer:
1/5
Step-by-step explanation:
Since there are 2 red marbles and since there are a total of 10 marbles, the probability is 2/10. This simplifies to 1/5. So the probability of picking a red marble is 1/5.
The probability of randomly picking out a red marble is 1/5
Calculating the probability of randomly picking out a marble and the marble being red?To determine the probability of randomly picking out a marble and it being red, we need to consider the total number of marbles and the number of red marbles.
Total marbles = 5 green + 3 blue + 2 red = 10 marbles
Red marbles = 2
So, we have
Probability = (Number of favorable outcomes) / (Total possible outcomes)
This gives
Probability = (Number of red marbles) / (Total marbles)
By subsituition
Probability = 2/10 = 1/5
Hence, the probability of randomly picking out a marble and it being red is 1/5
