Answer:
x= 4 or -10
Step-by-step explanation:
Answer:
x = - 10, x = 4
Step-by-step explanation:
Given
2(x + 3)² = 98 ( divide both sides by 2 )
(x + 3)² = 49 ( take the square root of both sides )
x + 3 = ± [tex]\sqrt{49}[/tex] = ± 7 ( subtract 3 from both sides )
x = - 3 ± 7
Thus
x = - 3 - 7 = - 10
x = - 3 + 7 = 4

4. Jeff and his brother Joe are saving money
to buy a video game that costs $52. Jeff
earns $8 each week mowing lawns and
spends $2 of it. Joe earns $10 each week
and spends $3 of it. Which expression can
be used to find out how many weeks it will
take for them to save for the video game?
52-[(8 + 2) - (10 + 3)]
b. 52 [(8-2) - (0 - 3)]
52 +[(8-2) + (10 - 3)]
d. 52 + [(8 + 2) + (10 + 3)1
a.
Answer:
52/[(8 - 2) + (10 - 3)]
Step-by-step explanation:
Jeff earns $8 and spends $2 each week.
Each week he keeps (8 - 2).
Joe earns $10 and spends $ each week.
Each week he keeps (10 - 3).
The total amount they keep each week is
(8 - 2) + (10 - 3).
If you divide the cost of the game by the amount they keep each week, you get the number of weeks.
Answer: 52/[(8 - 2) + (10 - 3)]

One line segment m is (3x + 5) units long and line segment n is (x - 10). What is the value of r if line segments m and n are congruent?
Answer:
I believe it is -17.5. Tell me if I am wrong
Step-by-step explanation:
3x + 5 = x - 10
-x -5 -x -5
2x = -15
x = -7.5
3(7.5) + 5
= 22.5 + 5
= -17.5

How many points need to be removed from this graph so that will be a function?
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The answer is you have to remove 4 points.
There is 6 points in all and for a function it only needs two points to become a function. A function needs to be a that line that passes the vertical line test. For example: A circle is not a function because when you perform the vertical line test you'll see that many points share a common x-value and a function needs only one output in every input.
Alberto wants to keep their favorite tree from being uprooted by heavy winds. They plan to tie 3 sections of rope to a band on the trunk of the tree, 5 feet above the ground. They will tie each section of the rope to a stake in the ground 12 feet out from the base of the tree. How much rope will he need altogether?
Answer:
39 ft
Step-by-step explanation:
Using the description as a guideline I have drawn out the situation (badly drawn) as seen in the picture below. From the picture, we see that we need to find x which is the length of one of the ropes. Once we have this length we simply multiply it by 3 to find out how much rope we need altogether. Since this is the diagonal of a triangle we can use the Pythagorean theorem to solve for x.
Pythagorean theorem: [tex]a^{2} +b^{2} = c^{2}[/tex] .... which a and b are the two sides while x is the diagonal.
[tex]5^{2} +12^{2} = x^{2}[/tex]
[tex]25 + 144 = x^{2}[/tex]
[tex]169 = x^{2}[/tex] ... now we square root both sides
[tex]13 = x[/tex]
Now that we have the length of one of the ropes we simply multiply this by 3 to find the total amount of rope needed.
13 * 3 = 39 ft
DO_ 1/2 of X is. please help
Answer:
x = 2
Step-by-step explanation:
Is it -1/2 or just 1/2 I'll just answer both
x = 4
So -1/2 of x or -1/2 of 4 is -2
And 1/2 of 4 is 2.
So the answer is most likely 2
and is probably point z
4/(-1/2) = -2
4/(1/2) = 2

8.5(4+3h)-h simplified
Answer:
24.5h + 34
Step-by-step explanation:
8.5(4 + 3h) - h
= 34 + 25.5h - h
= 24.5h + 34
I hope this helped!
The simplified form of 8.5(4+3h)-h is 24.5 + 34.
What is a numerical expression?A numerical expression is in the form of variables and constants separated by the operation of addition and subtraction. We can also form numerical expressions from statements.
Given an expression in variable h which is 8.5(4+3h)-h.
First, we'll apply distributive law to get rid of the bracket and separate the different terms. There are two more laws they are associative law and commutative law.
Distributive law state that a(b+c) = ab + bc.
34 + 25.5h - h.
24.5h + 34.

Answer: 46-3i
Step-by-step explanation: Use the FOIL method, (a+b)(c+d)=ac+ad+bc+bd. Collect like terms then simplify.
(6+7i)(3−4i)
18−24i+21i+28
(18+28)+(−24i+21i)
46-3i
- Hope this helps, have a blessed and wonderful day! :-)
In the standard form we can write (6 + 7i)(3 − 4i) as (- 3i + 46).
What are complex numbers?
A complex number is a number of the form a + bi, where [a] and [b] are real numbers and [i] is equal to [tex]\sqrt{-1}[/tex].
Given is the following complex expression -
(6+7i)(3−4i)
We have -
(6 + 7i)(3 − 4i)
On expanding, we get -
6(3 - 4i) + 7i(3 - 4i)
18 - 24i + 21i - 28i²
18 - 3i - 28i²
18 - 3i - 28 (-1)
18 - 3i + 28
46 - 3i
- 3i + 46
Therefore, in the standard form we can write (6 + 7i)(3 − 4i) as (- 3i + 46)

The drama club is selling tickets to their play to raise money for the
show's expenses. Each student ticket sells for $6 and each adult ticket
sells for $11. The auditorium can hold at most 100 people. The drama
club must make no less than $770 from ticket sales to cover the show's
costs. If x represents the number of student tickets sold and y
represents the number of adult tickets sold, write and solve a system of
inequalities graphically and determine one possible solution.
Answer:
Student tickets sold 66
Adult tickets sold 34
Step-by-step explanation:
x=6. y=11
x+y=100. Multiply by -6
6x+11y=770 Then combine terms
5y=170 Divide 5 on both sides
y=34 Then do 100-34
x=66
This is the solution for the club to not earn anything but able to cover the fees.
The inequality form can be written as,
total revenue=66x+34y in this case total revenue=0
Round 345,047 to the nearest thousand ten thousand hundred thousand
345,000 ; 350,00 ; 300,000.
Answer:
300,000
Step-by-step explanation:
the ten hundred thousands place would be
100,000
therefore the nearest ten hundred thousand would be
300,000
because the 345,047 isn't a high enough digit to be 5+ and make the nearest thousand 400,000 and not 300,000
If that doesn't help, think of it like this...
Anything before the place is what determines if the number will be higher or lower.
45 is lower than 50 and 50+ is the passing number to make the number 400,000.
Tip: when your rounding numbers the only numbers that stay the same and don't turn into 0's is like the 3 in "345,047" but the "45,047" part turns into 0's is because those aren't needed and because you rounded it, it's like it takes those numbers to make what you rounded to higher or lower.
so if you look at it like that the answer is 300,000.
