Answer:
Step-by-step explanation:
Here is an example:
[tex]3x^{2} +7=55[/tex]
-7 on both sides of the equation
[tex]3x^{2} =48[/tex]
divide by 3 on both sides
[tex]x^{2} =16[/tex]
square root the [tex]x^{2}[/tex] and 16
x=±4
I’m thinking of a number. When you multiply it by 3 and subtract 10 you will get a number less than 5. Form an inequality and solve it to describe the range of possible numbers
Answer:
[tex]3x-10<5\\x<5[/tex]
Step-by-step explanation:
Let x be equal to the number.
We can use what the question gives us to directly form a mathematical statement. When you multiply it by 3 (3x) and then subtract 10 (3x-10) you will get a number less than 5 (<5). Using this, our mathematical statement would look like this:
[tex]3x-10<5[/tex]
To find the range of possible values, we must solve the inequality and isolate x.
[tex]3x-10<5[/tex]
Add 10 to both sides
[tex]3x-10+10<5+10\\3x<15[/tex]
Divide both sides by 3
[tex]\frac{3x}{3}<\frac{15}{3}\\x<5[/tex]
I hope this helps!

Answer:
30
Step-by-step explanation:
3x - 27 = x +11
3x -27 +27 = 11 + 27
3x - x = x -x + 38
2x = 38
2x ÷ 2 = 38
X = 19
19 × 3 -27 = 30
Part A: If PM =PN and MPQ=UNPQ which triangle congruency postulate can we
use to determine APMQ = APNQ given the information on the figure?
OSAS
O SSS
O AAS
O ASA
Part b:How did you determine your answer in part A/Question 2?
Answer:the answer for part A is SAS.
Step-by-step explanation:
We already know that side PQ is the same length for both the triangles. We were then given the information that sides PM and PN were equal. So now we already have two sides that are the same. Then we were given the information that angle MPQ and angle NPQ were also equal. So now we have two sides and an angle that are equal. This is how we got SAS (side angle side). I tried my best to explain. I added a photo so you could see what I was trying to explain. Hopefully this helped!

Which statement best describes the domain of the function represented in the graph?
Given:
The graph of a function.
To find:
The correct statement for the domain of the given function graph.
Solution:
Domain is the set of x-values for which the function is defined or it is the set of input values.
From the given graph it is clear that it is a linear function with end points (1,2) and (9,14).
So, the given function is defined for [tex]1\leq x\leq 9[/tex]. Here 1 and 9 are including in the set of x-values.
Therefore, the correct option is C, i.e., [tex]1\leq x\leq 9[/tex] or x between 1 and 9, inclusive.

For questions 7 and 8 find the unknown angle.
Answer:
58 degrees for Question 7, and 71 degrees for Question 8
Step-by-step explanation:
For question 7:
180 - 99 = 81
81 + 41 = 122
180 - 122 = 58
For Question 8:
142 / 2 = 71
Answer: 7) 58 degrees 8) 71 degrees
Step-by-step explanation:
7) 41 + x = 99 degrees (the two interior opposite angle is equal to the exterior angle)
subtract 41 on both sides
x = (99 - 41) degrees
x = 58 degrees
8) x + x = 142 degrees
2x = 142
divide 2 on both sides
x = 71 degrees

What is the answerrr i need helpp :((((
Answer:
2r
Step-by-step explanation:
2r is the answer because:
We have to switch the -3r in to +3r and positive + positive = positive.
Then we change the add sign in to subtracting sign and we subtract:
3r-5r and it will give us:
2r
And we keep the answer positive because our answer was a +5r so the bigger number keeps the sign the same.

To prove that the triangle is scalene, calculate all the lengths of the sides.
The formula for a line like this is basically pythagorean theorem, which is
[tex]p = \sqrt{ {(y2 - y1)}^{2} + {( x2 - x1})^{2} } [/tex]
(x1, y1) and (x2, y2) are the respective vertexes.

Multiplication is a method of finding the product of two or more numbers. After 8 months the cost of computer processor is $72
What is Multiplication?multiplication is a method of finding the product of two or more numbers.
It is given that,
A computer processor costs initially $96.00
It is expected that in 8 months the processor will cost 3/4 its current price.
Which means its cost will 3/4 times of 96.
Whenever we use times it means product or multiply.
Three by four times of ninety six

Ellen Greenberg loves to make and fly kites. Ellen is planning to open a shop that
sells custom-made kites. She asks for your advice to help her set financial goals.
Ellen estimates that after expenses, she can make a $15 profit on each kite she
sells. If her annual income goal is $15,400, how many kites will she have to sell?
Answer:
She must sell 1026.66666667 kites
Step-by-step explanation:
15,400/15
The number of kites that Ellen needs to sell to complete her annual goal is 1027.
What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that Ellen can make a $15 profit on each kite she sells. Also, Ellen's annual income goal is to have $15,400. Therefore, the number of kites that Ellen needs to sell is,
Number of kites that Ellen will sell = Annual income goal/Profit on each kite
Number of kites that Ellen will sell = $15,400 / $15
= 1026.6667
Since Ellen can not sell half kites, therefore, she needs to sell 1027 kites to complete her annual income goal.
Hence, the number of kites that Ellen needs to sell to complete her annual goal is 1027.
