Solve: -2 < x + 3 < 5
Answer:
The answer is
[tex] - 5 < x < 2[/tex]
Step-by-step explanation:
First you have to seperate them :
[tex] - 2 < x + 3[/tex]
[tex]x + 3 < 5[/tex]
Next you can solve it by moving all the unrelated terms to the other side :
[tex] - 2 < x + 3 \\ - 2 - 3 < x + 3 - 3 \\ - 5 < x \\ x > - 5[/tex]
[tex]x + 3 < 5 \\ x + 3 - 3 < 5 - 3 \\ x < 2[/tex]
Answer:
-5 < x < 2
Step-by-step explanation:
Subtract 3 from each of the three sides.
-2 < x + 3 < 5
-2 - 3 < x + 3 - 3 < 5 - 3
-5 < x < 2
In the figure, b and c are parallel lines. Which of the following statements are true?
1.Joe claims the measure of angle 3 is equal to 90 degrees.Is he correct?why or why not
2.state the measure of angle 5 and how you know
Thank you!
Answer:
1. No, Joe is not correct
2. [tex]\angle 5=72^{\circ}[/tex]
Step-by-step explanation:
Given: b and c are parallel lines
To find:
1. whether the given statement is correct or not
2. [tex]\angle 5[/tex]
Solution:
1.
Sum of two angles that form a linear pair is equal to [tex]180^{\circ}[/tex]
[tex]\angle 3+72^{\circ}=180^{\circ}[/tex] (linear pair)
[tex]\angle 3=180^{\circ}-72^{\circ}=108^{\circ}\neq 90^{\circ}[/tex]
So, Joe is not correct
2.
If two lines are parallel then alternate interior angles are equal.
As b and c are parallel lines,
[tex]\angle 5=72^{\circ}[/tex] (alternate interior angles)

Answer:
C. Acute and Isosceles
Step-by-step explanation:
Acute means the angles are less than 90 degrees. All of the triangles angles are less than 90 degrees.
Isosceles means they have 2 sides of equal length. In the triangle, there are 2 sides with the length of 6 in, making this an isosceles triangle

Rita had a roll of film developed for $7.38. Her flash wasn't working so only 9 pictures turned out. How much did each picture cost her?
A.
$16.38
B.
$1.64
C.
$0.82
D.
$66.42
Answer:
D. $66.42
Step-by-step explanation:
If I'm correct (which I highly doubt...)
You multiply 7.38 and 9
That should give $66.42
Sorry if I'm wrong...
And if I'm wrong, my second option would be C. $0.82
What is the percent of change in the cost of a DVD set that originally sold for$69.99 and is now on sale for $44.99? Round your answer to the nearest whole number.
Answer: 36%; yes, the % change is equal to the percent discount
Step-by-step explanation:
Initial price = $69.99
Final price = $44.99
change in price = |(final - initial)|
change in price = |(44.99 - 69.99)|
change in price = $25
25/69.99 = x/100
100(25/69.99) = x
100(0.357) = x
35.7% = x
x = 36%
Use sigma notation to represent the sum of the first six terms of the following sequence: −10, −13, −16, …
Answer:
c
Step-by-step explanation:
i took the test and got it right so... and do you have Mr. Hoffman
The sum of the first six terms of the following sequence is ∑(from i=1 to 6) (-10 - 3(i-1)), the correct option is A.
What is the sum of terms of a geometric sequence?Lets suppose its initial term is f=a , multiplication factor is r
and let it has total n terms, then, its sum of a geometric sequence is given as:
[tex]S_n = \dfrac{a(r^n-1)}{r-1}[/tex]
(sum till nth term)
We are given that;
The sequence; −10, −13, −16, …
Now,
The given sequence is an arithmetic sequence with first term (a1) = -10 and common difference (d) = -3.
Using this formula, we can find the first six terms of the sequence as follows:
a1 = -10
a2 = -10 + (-3) = -13
a3 = -10 + 2(-3) = -16
a4 = -10 + 3(-3) = -19
a5 = -10 + 4(-3) = -22
a6 = -10 + 5(-3) = -25
We can represent the sum of the first six terms using sigma notation as:
∑(from i=1 to 6) ai = (-10) + (-13) + (-16) + (-19) + (-22) + (-25) = -105
The sum of the first six terms of the given sequence is -105.
Using sigma notation, we can write this as:
∑(from i=1 to 6) (-10 - 3(i-1)) = -105
Therefore, by the geometric sequence the answer will be ∑(from i=1 to 6) (-10 - 3(i-1)).

Meera has been visiting banks all day trying to find the best compound interest rate for her savings account. The banks have decided that instead of telling her their rate, they are going to give her the equation that will calculate her current balance after t years. Below are the equations each bank gave to Meera, where f(t) is the balance after t years and P is the principal amount to be placed in the savings account. Select the equation of the bank that has the greatest compound interest rate. Select one:
A. f(t) = P(1.07)t
B. f(t)= P(1.03)2t
C. f(t) = P(1.02)4t
D. f(t) = P(0.90)t
Answer: C.
f(t) = P(1.02)4t
Step-by-step explanation:
f(t) = P(1.02)4t will have the greatest compound interest because the interest is on quarterly bases with an increment of 1.02 and the rate of 8%
Note : 8/100 × 1/4 = 0.02
There is no increment in D and A is yearly based. Option C is for 6 month.

Answer:
25) x = 18 26) x = 50
Step-by-step explanation:
25) 108 + 4x = 180
108 + 4x = 180
-108 -108
4x = 72
x = 18
26)
101 + (x + 29) = 180
101 + 29 + x = 180
130 + x = 180
-130 -130
x = 50

What's the eleventh term of a sequence with an explicit rule of ƒ(n) = 2 + 3(n – 1)?
Question 16 options:
A)
ƒ(11) = –31
B)
ƒ(11) = 32
C)
ƒ(11) = 23
D)
ƒ(11) = –22
Answer:
B. F(11) = 32
Step-by-step explanation:
From the explicit equation,
F(n) = 2 + 3(n - 1)
F(11) = 2 + 3(11 - 1)
F(11) = 2 + 33 - 3
F(11) = 35 - 3
F(11) = 32
The 11th term of the sequence with an explicit rule is 32

51 – 2z - 8z = 23
Answer: z=2.8
This is how I do!
Step-by-step explanation:
51-2z-8z=23
We simplify the equation to the form, which is simple to understand
51-2z-8z=23
We move all terms containing z to the left and all other terms to the right.
-2z-8z=+23-51
We simplify left and right side of the equation.
-10z=-28
We divide both sides of the equation by -10 to get z.
z=2.8
Answer:
Z=2.8
Step-by-step explanation:
51-10z=28
