Answer:
The graph shows the given straight line.
Step-by-step explanation:
We are given an equation:
[tex]y = \displaystyle\frac{1}{3}x + 3[/tex]
The attached image shows the graphical plot for the given equation.
If we compare the given equation to the
[tex]y = mx+c[/tex]
where m is the slope and c is the y-intercept of the straight line.
Comparing, we get:
[tex]m = \displaystyle\frac{1}{3}\\\\c = 3[/tex]
The line will pass by the points (-3, 2), (0, 3), and (3, 4)
Given is an equation y = x/3+3 we need to graph it,
Let's pick a few x-values and determine the y-values that go with them:
Y equals (1/3) when x = -3(-3) + 3 = -1 + 3 = 2
Y = (1/3)(0) + 3 = 0 + 3 = 3 when x = 0.
Y = (1/3)(3) + 3 = 1 + 3 = 4 for x = 3.
The points (-3, 2), (0, 3), and (3, 4) can now be plotted on the coordinate plane.
A straight line running across these locations will form the graph.
The line will have a positive slope because the value of x is positive (1/3).
Given that the y-intercept is 3, the line will cross the y-axis at (0, 3).
The plotted points (-3, 2), (0, 3), and (3, 4) lie on the line, and the line continues indefinitely in both directions.

How can Brady use fraction strips to show that 3 4 and 7 8 are NOT equivalent?
Answers
Next Brady needs seven strips that each represent one eighth (1/8). He needs to line them up end to end. The new long strip he has created represents 7/8.
If the two long strips he created were equal then 3/4 would equal 7/8 but as they are not equal this is not the case. Since the strip for 7/8 is longer, the fraction 7/8 is greater than 3/4.
To demonstrate that 3/4 and 7/8 are not equivalent, Brady can use fraction strips to visually compare the colored portions of the strips, which will clearly show that 7/8 is greater than 3/4 as it has more colored sections.
Explanation:To show that 3/4 and 7/8 are not equivalent using fraction strips, Brady can follow these steps:
Take one strip and divide it into four equal parts to represent the fraction 3/4. Color three of these parts.Take another strip, divide it into eight equal parts to represent the fraction 7/8, and color seven of these parts.Compare the two colored strips side by side.Brady will observe that the strip representing 7/8 has more colored sections than the strip representing 3/4, even though the strips are the same length. This visual comparison confirms that 3/4 is less than 7/8, thus they are not equivalent fractions. The fraction 7/8 is only one-eighth away from being a whole, whereas 3/4 is one-fourth away.

Why is it most logical to let x represent Dianna’s current age?
Answers
in 3 years, she's going to be " x + 3 " years old.
33 years ago, she was " x - 33 " old.
how much is 4 times that anyway? well 4(x-33), that's 4 times as 33 years ago her age.
now, we know in 3 years, x+3, she'll be "4 times as old as she was 33 years ago", 4(x-33), therefore, those amounts are equal then,
[tex]\bf \stackrel{\textit{3 years from now}}{x+3}~~=~~\stackrel{\textit{4 times as old as she was 33 years ago}}{4(x-33)} \\\\\\ x+3=4x-132\implies 135=3x\implies \cfrac{135}{3}=x\implies 45=x[/tex]
why is it most logical to use "x" for her age today?
well, because 3 years from now is just x + 3

Option: A is correct (congruent triangles)
Step-by-step explanation:
To prove that he diagonals of a parallelogram bisect each other we have to go through the following steps:
Angle DBA is congruent to angle BDC. Angle CMD is congruent to angle AMB. Triangle CMD is congruent to triangle AMB. Segment AM is congruent to segment MC. M is the midpoint of segment AC. Segment BD bisects segment AC. Segment BM is congruent to segment MD. M is the midpoint of segment BD. Segment AC bisects segment BD.Hence we have to use the concept of congruent triangles in order to prove that the diagonals of a parallelogram bisect each other.
Hence, option A is correct

Any rational root of f(x) is a multiple of 9 divided by a multiple of 12. Any rational root of f(x) is a factor of 12 divided by a factor of 9. Any rational root of f(x) is a factor of 9 divided by a factor of 12.
Answers
Answer:
Any rational root of f(x) is a factor of 9 divided by a factor of 12.
Step-by-step explanation:
Given:
f(x) = 12x³– 5x² + 6x + 9
Required; Rational root of f(x)
The rational root theorem states that: each rational solution
x = p⁄q, written in lowest terms so that p and q are relatively prime
Where
p = factors of the constant
q = factors of the lead coefficient.
Given that
f(x) = 12x³– 5x² + 6x + 9
The constant is 9
And the lead coefficient is 12
The factor of these two are
9; ±1 , ±3, ±9
12: ±1, ±2, ±3, ±4, ±6, ±12
Then the rational root of f(x) is
factor of 9 divided by a factor of 12.
Possible Rational Roots
= (±1 , ±3, ±9) / (±1, ±2, ±3, ±4, ±6, ±12)
The correct statement according to the rational root theorem is
The rational root of f(x) is
factor of 9 divided by a factor of 12
What is 5/15 written as a decimal???
What is 4/15 written as a decimal???
What is 3/15 written as a decimal???
Answers
There are a couple ways we can use to convert a fraction to a decimal, but let's stick with the easiest one.
To convert a fraction to a decimal, simply divide the numerator (top part of the fraction) by the denominator (bottom part).
The first fraction is 5/15. Its numerator is 5, and its denominator is 15. Divide the top by the bottom.
5 ÷ 15 = 0.3333333333
Because this decimal keeps repeating, it is called a "repeating fraction."
We don't want to write all those 3's over and over again, so to indicate that it is a repeating decimal, simply put a bar above the 3.
Convert the other two fractions using the same method:
4 ÷ 15 = 0.266666667
Remember to put a bar above the repeating number.
3 ÷ 15 = 0.2
Since this decimal does not repeat, it is called a "terminating decimal". You do not have to put a bar above the 2.
Don't forget this method!
Do 1.5 cm, 3 cm, 1.5 cm make a triangle and what kind
Answers
The lengths 1.5 cm, 3 cm, and 1.5 cm cannot form a triangle because the sum of the lengths of the two shorter sides is equal to the length of the longest side, which does not satisfy the Triangle Inequality Theorem.
The question asks if lengths 1.5 cm, 3 cm, and 1.5 cm can form a triangle, and if so, what kind of triangle it would be. To determine whether these lengths can form a triangle, we use the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
For these lengths:
1.5 cm + 1.5 cm = 3 cm1.5 cm + 3 cm > 1.5 cm1.5 cm + 3 cm > 1.5 cmWe see that when we add the lengths of the two shorter sides (1.5 cm + 1.5 cm), it equals the length of the longest side (3 cm). According to the Triangle Inequality Theorem, the lengths do not meet the condition for forming a triangle because the sum must be greater than, not equal to, the length of the third side. Therefore, these lengths cannot form a triangle.

Find a second-degree polynomial p such that p(1) = 5, p'(1) = 7, and p''(1) = 10.
Answers
p'(x) = 2ax +b
p''(x) = 2a
You require
.. 2a = 10
.. 2a +b = 7
.. a + b + c = 5
Thus a=5, b=-3, c=3, and
.. p(x) = 5x^2 -3x +3
The given conditions suggest a second-degree polynomial of form p(x) = ax^2 + bx + c. By solving the given conditions a = 5, b = -3, and c = 3, yielding the polynomial p(x) = 5x^2 - 3x + 3.
Explanation:The question is asking for a second-degree polynomial, which can generally be written in the form p(x) = ax^2 + bx + c. Given that p(1) = 5, that means a + b + c = 5. The derivative of p(x), p'(x) = 2ax + b, and p'(1) = 7, so 2a + b = 7. The second derivative, p''(x) = 2a, and p''(1) = 10, so 2a = 10 or a = 5. We can substitute a = 5 into the first two equations to find the values of b and c. So, b = -3 and c = 3. Therefore, the original function is p(x) = 5x^2 - 3x + 3.

2. "D" and "x" are congruents, because they are Alternate Interior angles, so x=38º.
3. "A", "B" and "C" form a the triangle ABC. Then, we remember sum of the interior angles of a triangle is 180º, so we have:
76º+38º+B=180º
B=180º-76º-38º
B=66º
4. By definition, an exterior angle of a triangle is equal to the sum of the opposite interior angles to it. So, we can calculate the exterior angle "y" of the triangle ABC, as follows:
The opposite angles are: 76º and 66ª. Then, we obtain:
y=76º+66º
y=142º
Therefore, the answer is: The value of y is 142º.

The idea is to go through each answer choice and see if that value is in the range. To do so, draw a horizontal line from that value at the y axis and see if it crosses the graph.
So for example, for choice A, we draw a horizontal line through -2 on the y axis. You'll see that the horizontal line crosses the green part of the piecewise function graph. So y = -2 is in the range. Similar situations will happen for B and C as well.
The only time that this doesn't happen is when y = 5. Draw a horizontal line through 5 on the y axis. This horizontal line is too high to cross through any part of the piecewise function. So y = 5 is not in the range.

Step-by-step explanation:
We have been given a triangle and we are asked to solve for x using angle bisector theorem.
Angle bisector theorem states that if a ray bisects an angle of a triangle, then it divides the opposite side of triangle into segments that are proportional to the other two sides.
Using angle bisector theorem we can set an equation as:
[tex]\frac{4x+1}{5}=\frac{15}{3}[/tex]
Let us solve for x by multiplying both sides of our equation by 5.
[tex]\frac{4x+1}{5}*5=\frac{15}{3}*5[/tex]
[tex]4x+1=5*5[/tex]
[tex]4x+1=25[/tex]
Let us subtract 1 form both sides of our equation.
[tex]4x+1-1=25-1[/tex]
[tex]4x=24[/tex]
Upon dividing both sides of our equation by 4 we will get,
[tex]\frac{4x}{4}=\frac{24}{4}[/tex]
[tex]x=6[/tex]
Therefore, the value of x is 6 units.
