1. Find the value for t that's makes the given equation true. 12=-t-11
2. Solve each equation for it's variable.
8(m-2)=3(m+3)
n-24/8=n
Pls help 40 points
Step-by-step explanation:
The given equation is 12x2+4kx+3=0

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]
Identify like terms in the expression. 12n-6+p+6n
Answer:
18n+p-6
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:
[tex]\bold{12n+6n-6+p}[/tex]
[tex]\bold{18n-6+p}[/tex]
Hence, the answer is
[tex]\boxed{\boxed{\bold{18n-6+p}}}[/tex]
Hope everything is clear.
Let me know if you have any other questions; if so, please comment.

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.

If you bought 1000 shares of a Vanguard Mutual Fund for $145 a share two years
ago and it is now worth $265. How much would you make if you sold the mutual
fund now?
$120,000
$145,000
$265.000
$1,200
Answer:
$120000
Step-by-step explanation:
1000 X 145 = 145000
1000 X 265 = 265000
$265000 - $145000 = 120000
Isaac is multiplying 4 x 3/4. His work
is shown below. Fill in the missing
numbers to complete the problem.
4* 3/4= ?* [? *1/4).
= ( ?* ?) * 1/4
= ?* 1/4 = ? /4= ?
Answer:
match your blanks to the solution below
Step-by-step explanation:
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.
[tex]4\times\dfrac{3}{4}=4\times\left(3\times\dfrac{1}{4}\right)\\\\=(4\times3)\times\dfrac{1}{4}\\\\=12\times\dfrac{1}{4}=\dfrac{12}{4}=3[/tex]
__
Additional comment
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]
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

What value of x makes this equation true? 12 x minus 15 = 6 minus 3 x
Answer:

Mixed Form 1 2/5
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Step-by-step explanation:
