Answer:
Keiko sent 17 messages, Dale sent 10 messages, and Tony sent 68 messages
Step-by-step explanation:
Let x represent the number of messages that Keiko sent.
Since Dale sent 7 less than Keiko, his number can be represented by x - 7
Since Tony sent 4 times as many as Keiko, his number can be represented by 4x
Using these variables, create an equation:
(x) + (x - 7) + (4x) = 95
Add like terms and solve for x:
6x - 7 = 95
6x = 102
x = 17
So, Keiko sent 17 messages.
Subtract 7 from this to find how many Dale sent:
17 - 7
= 10
Multiply it by 4 to find how many Tony sent:
17(4)
= 68
So, Keiko sent 17 messages, Dale sent 10 messages, and Tony sent 68 messages
What is the difference of the polynomials:
(3x2 + 4x + 8) - (2x2 + 2x + 5)
a x^2 + 2x + 3
b x^2 + 6x + 3
c x^4 + 2x^2 + 3
d x^4 + 6x^2 + 13
Answer:
(6+4x+8)-4-2x-5

If m = 27 and n = 4, what is the value of the following expression?
Answer:
2
Step-by-step explanation:
m - 5 • n + 5
plug it in
27- 5 * 4+5
well, we gotta follow PEMDAS (there are no parentheses)
5*4
20
now we have
27-20+5
20+5
25
27-25

PLEASE HELP Is A'B'C'D' a translation, rotation, or reflection of ABCD? Explain how you can tell.
Answer:
1. Is A'B'C'D' a translation, rotation, or reflection of ABCD? Explain how you can tell.
A'B'C'D' is a reflection over the y-axis. By flipping ABCD over the y-axis, the result will be A'B'C'D'
2. Is A"B"C"D" a translation, rotation, or reflection of A'B'C'D'? Explain.
A"B"C"D" is a rotation of A'B'C'D'. This is proven by the fact that if A'B'C'D' is rotated 90 degrees, the result will be A"B"C"D".
3. Suppose the measure of ∠B is 89°. Which other angles must measure 89°? How do you know?
If ∠B measures 89 degrees, then all other B angles must also measure 89 degrees because the angle is not changed by any of the transformations performed.
4. What is the perimeter of A"B"C"D"? Explain how you found the perimeter.
Because the size and shape are not any different from the original figure, the perimeter is 26.3 units.
6+6+6.3+8=26.3

Answer:
Option C and D are the correct answer.
Step-by-step explanation:
If x > -3, then the values which satisfy the inequalities can be represented on a number line which is shown above.
Then the range of values that satisfies the inequalities are numbers to the right of -3 which are: -2, -1, 0, 1, 2, 3, 4, 5 --- up to positive infinity.
From the options provided only 0 and -1 satisfies the range.
Option C and D are correct.

? = [tex]tan^{-1}[/tex](11/24)
**PUT [tex]tan^{-1}[/tex](11/24) INTO CALCULATOR
Step-by-step explanation:
1. tan(?)=11/24
--> 11/24: SOH, CAH, TOA: sin(x)=opposite side of the x/hypotenuse, cos=adjacent side of the x/hypotenuse, tan=opposite side of the x/adjacent side
2. to get ? of tan you can't divide tangent, you have to do the inverse function, which is [tex]tan^{-1}[/tex], and put it into the calculator

move the costant to the right, change the sign
3d=-2-1
caclulate
3d=-3
divide both sides by 3
d=-1
