Hi! I need help multiplying, adding, and subtracting fractions, could someone help meh? ~bewuga
Answer:
yes i can
Step-by-step explanation:
adding fractions you only add the numerator numbers, the denominator numbers stay the same, subtracting fractions you just subtract the numerator as the denominator stays the same, while multiplying you multiply both numerator and denominator
Answer:
addition and subtraction is possible when denominator are same so to make denometor same multiplication is use on both numerator and denominator
Step-by-step explanation:
for example,
5/10+2/5
now we can't add those numbers so
multiply on both on numerator denominator by same number to make denominator same.
look
5*1/10*1 + 2*2/5*2
5/10+4/10.
(addition is possible bcz denominator are same)
(5+4)/10
9/10 is answer
50 points hlep Explain how to graph a polynomial function in factored form. What do the factors mean in terms of the polynomial? Graph f(x)=(x−2)^2 (x+1) (x−4)
Answer:
Given function: [tex]f(x)=(x-2)^2 (x+1) (x-4)[/tex]
The factors give us the zeros (x-intercepts) of the graph.
To find the zeros, set the function to zero and solve for x:
[tex](x-2)^2 (x+1) (x-4)=0[/tex]
Therefore,
[tex](x-2)^2=0\implies x-2=0 \implies x=2[/tex]
[tex](x+1)=0\implies x=-1[/tex]
[tex](x-4)=0 \implies x=4[/tex]
So the zeros are at (2, 0) (-1, 0) and (4, 0)
The multiplicity of a zero is the number of times the factor appears in the fully factored form of the polynomial, i.e. the exponent on the corresponding factor.
[tex]x = 2[/tex] has a multiplicity of 2[tex]x=-1[/tex] has a multiplicity of 1[tex]x=4[/tex] has a multiplicity of 1If the zero has an even multiplicity, the graph touches and bounces off the x-axis at that point.
If the zero has an odd multiplicity, the graph crosses the x-axis at that point.
To find the y-intercept, expand the function:
[tex]f(x)=x^4-7x^3+12x^2+4x-16[/tex]
Set [tex]x = 0[/tex] and solve:
[tex]f(0)=(0)^4-7(0)^3+12(0)^2+4(0)-16=-16[/tex]
Therefore, the y-intercept is at (0, -16)
The end behavior of a polynomial function is the behavior of the graph of f(x) as x approaches positive infinity or negative infinity.
As the leading degree is 4 (even) and the leading coefficient is positive, the end behavior of the function is:
[tex]f(x) \rightarrow + \infty \textsf{ as } x \rightarrow - \infty[/tex]
[tex]f(x) \rightarrow + \infty \textsf{ as } x \rightarrow + \infty[/tex]
Sam is developing a metric to try to measure how generous an individual is. In order to evaluate whether it is actually measuring generosity, Sam is checking to see if there is any correlation between a person's score on the metric and the amount of money they donate to charities or give to others in need. In other words, Sam is evaluating the _____ of the metric.
By checking to see if there is correlation, Sam is evaluating the criterion validity of the metric.
How to determine the measured parameter of the metricFrom the question, we understand that Sam tests the metric to check for the presence or absence of correlation in the metric.
This, in other words means that Sam is checking the criterion validity of the metric.
Hence, the true statement is that Sam is evaluating the criterion validity of the metric.

Answer:
perpendicularStep-by-step explanation:
Calculate the slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Let m₁ and m₂ are the slopes of AB and CD.
Then
if m₁ = m₂ → lines are parallel
if m₁ · m₂ = -1 → lines are perpendicular
[tex]A(0;\ -4);\ B(-1;\ -7)\\\\m_{AB}=\dfrac{-7-(-4)}{-1-0}=\dfrac{-7+4}{-1}=\dfrac{-3}{-1}=3\\\\C(3;\ 0);\ D(-3;\ 2)\\\\m_{CD}=\dfrac{2-0}{-3-3}=\dfrac{2}{-6}=-\dfrac{2:2}{6:2}=-\dfrac{1}{3}[/tex]

B. If two triangles are not congruent, then their corresponding angles are not congruent.
C. If two triangles are congruent, then their corresponding angles are congruent.
D. If the corresponding angles of two triangles are not congruent, then the triangles are not congruent.
Answer:
A
Step-by-step explanation:
A, because you just have to flip the cause and effect.
If two triangles are congruent, then their corresponding angles are congruent.
So, if the corresponding angles are congruent, then the triangles are congruent
You can use this property for problems similar to this one, that have cause and effect relationships.

Answer:

Step-by-step explanation:
you combine 12 and 6, then put the exponents in order
Hey there!
Like terms are "from the same family"
Let me clarify.
For example. we have an expression "2t+12h-6h"
In this case, 12h and -6h are like terms and 2t and 12h are not like terms.
Here's another example:
r+a-y+4+9-1
The like terms are:
4, 9, and -1
Now that we know what like terms are, let's identify the like terms in the given expression.
The expression is:
[tex]\bold{12n-6+p+6n}[/tex]
What are the like terms?
That's right, 12n and 6n:

Submit
..
Answer:
its D
Step-by-step explanation:
i got it wrong, thank me latter
The projected sales after 2 years will be $389,350 which is the correct answer would be option (D).
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
Last year's store had total sales of $367,000.
The sales are to increase by 3% per year for the next 2 years.
To determine the projected sales in 2 years
The projected sales in next year = 3% of $367,000 + $367,000
The projected sales in next year = (3/100) × 367,000 + 367,000
The projected sales in next year = 11,010 + 367,000
The projected sales in next year = $378,010
The projected sales after 2 year = 3% of $378,010 + $378,010
The projected sales after 2 year = (3/100) × 378,010 + 378,010
The projected sales after 2 years = 11,340 + 378,010
The projected sales after 2 years = $389,350
Thus, the projected sales after 2 years will be $389,350.

The multiplication of an integer and a fraction has you multiply the integer by the numerator, then express the result over the denominator. At that point, you can reduce the fraction, if possible.

Because multiplication is commutative and associative, this can be done in a way that is a little simpler.
[tex]4\times\dfrac{3}{4}=4\times\left(3\times\dfrac{1}{4}\right)\\\\=3\times\left(4\times\dfrac{1}{4}\right)\\\\=3\times\dfrac{4}{4}=3\times1=3[/tex]
