Step-by-step explanation:
we know that midpoint of a segment is found from formula
x=(x1+x2)/2
and y=(y1+y2)/2
in this case x=3 and y=4 x2=-1 and y2=2
so x1=2x-x2 =2*3-(-1)=6+1=7
y1=2y-y2=2*4-2=8-2=6
the other endpoint is (7,6)

Last year, Gena’s food cart business was $225 in debt. This year, the debt has tripled. Which expressions show how much Gena’s business is currently in debt? Check all that apply.
225(3)
(3)(–225)
–225 + 3
3 – 225
–225(3)
(3)(–225)
–225 + 3
3 – 225
–225(3)
Answer:
(3)(-225) and -225(3).
Step-by-step explanation:
First, since ¨in debt¨ is describing negative value, all of the expressions that have positive 225 is incorrect. Also, since the term ¨triple¨ is describing multiplcation, any expression that does not have multiplication is also incorrect. This process of elimination leads to two answers, which both are correct.
Answer:
A. 225(3)
B. (3)(–225)
C.–225 + 3
D. 3 – 225
E. –225(3)

in the expression of (x + 1)^n, the coefficient of the x^3 term is two times the coefficient of the x^2 term. Find the value of n.
According to Khayyam-Pascal triangle ,
the value of n is 8.
[tex] look \: \\ \\ {(x + 1)}^{8} = {x}^{8} + 8 {x}^{7} + 28 {x}^{6} + 56 {x}^{5} + 70 {x}^{4} + 56 {x}^{3} + 28 {x}^{2} + 8x + 1 \\ \frac{56}{28} = 2 [/tex]
Recall the binomial theorem:
[tex](a+b)^n=\displaystyle\sum_{k=0}^n\binom nk a^k b^{n-k}[/tex]
where
[tex]\dbinom nk=\dfrac{n!}{k!(n-k)!}[/tex]
is the binomial coefficient. So
[tex](x+1)^n=\displaystyle\sum_{k=0}^n\binom nk x^k[/tex]
The x² term occurs for k = 2, which has coefficient
[tex]\dbinom n2=\dfrac{n!}{2!(n-2)!}=\dfrac{n(n-1)}2[/tex]
The x³ occurs for k = 3, with coefficient
[tex]\dbinom n3=\dfrac{n!}{3!(n-3)!}=\dfrac{n(n-1)(n-2)}6[/tex]
The latter coefficient is twice the other one, so that
[tex]\dfrac{n(n-1)(n-2)}6=2\cdot\dfrac{n(n-1)}2[/tex]
Solve for n :
[tex]\dfrac{n(n-1)(n-2)}6=n(n-1)[/tex]
[tex]n(n-1)(n-2)=6n(n-1)[/tex]
[tex]n-2=6[/tex]
[tex]\boxed{n=8}[/tex]

Answer:
RS: 26
ST: 40
Step-by-step explanation:
RS + ST = RT
3x - 16 + 4x - 8 = 60
3x + 4x - 16 - 8 = 60
7x - 24 + 24 = 60 + 24
7x = 84
7x / 7 = 84 / 7
x = 12
---------------------------------------

---------------------------------------
ST
4x - 8
4 (12) - 8

----------------------------------------
RS + ST = RT
20 + 40 = RT
60 = RT

Find the area of triangle DEF with vertices D(-1,2), E(3,-2) and F(-2,-2).*
Answer:
The area of the triangle DEF is 10.
Step-by-step explanation:
Area of a Triangle:
A triangle of base B and height H (both must be perpendicular) has an area of:
[tex]\displaystyle A=\frac{BH}{2}[/tex]
The image below shows the triangle formed by the points DEF. It's important to notice the points E and F lie on the same horizontal line because they both have the same y-coordinate.
This fact simplifies the calculations since we can easily compute the length the of base as the difference of their x-coordinates:
B=3-(-2)=3+2=5
Being the base of a horizontal line, the height of the triangle can be calculated as the difference of y-coordinates of D and the height of that line.
H=2-(-2)=4
With these two values, we calculate the area:
[tex]\displaystyle A=\frac{5*4}{2}=10[/tex]
The area of the triangle DEF is 10.

(2x2+4−x3)+(−4x2+6x3−2)
Express the answer in standard form.
Enter your answer in the box.
The simplified form of the expression (2x^2+4−x^3)+(−4x^2+6x^3−2) in standard form is -2x^3 + 2x^2 + 2.
What is an expression?
An expression is a mathematical phrase that can contain numbers, variables, and operators. It represents a value or a calculation, but it is not simplified to a single value.
To simplify the expression (2x^2+4−x^3)+(−4x^2+6x^3−2) in the standard form, we can combine like terms and apply the order of operations.
Step 1: Add and subtract the terms inside the first set of parentheses:
2x^2 + 4 - x^3 + (-4x^2 + 6x^3 - 2)
Step 2: Combine like terms:
-2x^3 + 2x^2 + 4 - 2
Step 3: Rearrange the terms in standard form, which is the form with the variable with the highest exponent first, and the numerical constant last:
-2x^3 + 2x^2 - 2 + 4
Step 4: Combine the constant terms:
-2x^3 + 2x^2 + 2
Hence, The simplified form of the expression (2x^2+4−x^3)+(−4x^2+6x^3−2) in standard form is -2x^3 + 2x^2 + 2.

2t + 8 is greater than or equal to -4 ( t + 1 ), whats the answer to the equation?
Step-by-step explanation:
2t + 8 > - 4( t + 1)

2t + 4t < - 4 +8
6t < 4
Divide both sides by 6

twelve is no more than the sum of -1.5 times a number w and 4
Answer:
w < -5.33333
Step-by-step explanation:
Step 1: Write inequality
12 < -1.5w + 4
Step 2: Solve for w
Subtract 4 on both sides: 8 < -1.5wDivide both sides by -1.5: -5.3333 > wRewrite: w < -5.33333Here we see that any value smaller than -5.3333 will work.
