what’s the solution of 4= -2(x-3)
Step-by-step explanation:
Simplifying 4 + -2(x + -3) = 24 Reorder the terms: 4 + -2(-3 + x) = 24 4 + (-3 * -2 + x * -2) = 24 4 + (6 + -2x) = 24 Combine like terms: 4 + 6 = 10 10 + -2x = 24 Solving 10 + -2x = 24 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + -2x = 24 + -10 Combine like terms: 10 + -10 = 0 0 + -2x = 24 + -10 -2x = 24 + -10 Combine like terms: 24 + -10 = 14 -2x = 14 Divide each side by '-2'. x = -7 Simplifying x = -7

What is the horizontal shift for the absolute value function below? Explain how you know using complete sentences.
F(x)=3 | x+6 | +9
Answer:
The horizontal shift is 6 units left (so -6).
Step-by-step explanation:
The horizontal shift is located inside the absolute value bars. While F(x) adds 6 to x, so you may think it's 6 units right, horizontal shifts are backwards as opposed to vertical shifts: we go 6 units left.

Which kind of function best models the data in the table? Graph the data and write an equation to model the data.
A. linear; y = x – 1
B. quadratic; y = x2 – 1
C. exponential; y = 3x – 1
D. linear; y = –x – 1
Answer:
D. linear; y = –x – 1
Step-by-step explanation:
Linear; y=-x - 1
The slope is negative since it’s decreasing. So it’s not the first equation. It’s not a quadratic equation because there is no forming U shape for this data. It’s not a exponential function because the slope is not 3 and a exponential function is in the form y=a(b)^x
Answer:
The correct answer is D) linear; y = –x – 1
Step-by-step explanation:
To find this, use any values in the table and it will produce a true statement. This is how we check to see if a model is correct. See the two examples below for proof.

To find out the answer, we need to first find how much money it is to buy 1 kg of almonds.
So, do 34 divided by 4.
[tex]\frac{34}{4} = 8.5[/tex]
Now, multiply 8.5 by 5.
8.5 × 5 = 42.5

The length of a rectangle is 11cm more than the width. The perimeter is 90cm. Find the length and width of the rectangle.
Answer:
Length=22.5cm, Breadth=11.5cm
Step-by-step explanation:
Let length be l and width be w.
w+22=l
w+w+w+22+w+22=90
4w=90-22-22
=46
w=46 divided by 4
=11.5
l=11.5+11
=22.5
Hence,
Length of rectangle=22.5cm
Breadth of rectangle=11.5cm
Supposed a certain game is fair and costs $4 if you lose and has a net payoff of $9 if you win. The only
possible outcomes of the game are winning and losing.
What is the probability of winning?
Answer:
32.5% Win Rate
Step-by-step explanation:
I got this answer by first:
( 9 ) * x + ( -4 ) * ( 1 - x ) = 0
9x - 4 + 4x = 0
13x = 4
then finally:
13/4 = 3.25 | And to get that into percent you multiply that by 10, giving you a 32.5% win rate. or 325 / 1000. Meaning you will win 325 out of 1000 games you play. Hope this helped!
Probability of winning is 0.69.
What is probability?Probability denotes the possibility of the outcome of any random event. The meaning of this term is to check the extent to which any event is likely to happen.
According to the question
Supposed a certain game is fair and costs $4 if you lose and has a net payoff of $9 if you win.
The only possible outcomes of the game are winning and losing.
The probability of winning = [tex]\frac{9}{4+9}[/tex]
= [tex]\frac{9}{13}[/tex]
= 0.69
Hence, probability of winning is 0.69.

Answer:
Step-by-step explanation:
I don't think they are. It sounds like a direct proportion to me. The more rice you buy, the higher the cost.
Cost = k * quantity.

Given: angle 1 = angle2,
m angle 1 = x + 14,
m angle 2 = y - 3
Solve for y in terms of x.
The solution of the given angle of the equation is y＝17＋x
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that performs the arithmetic operations are called arithmetic operators.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
We have given angle as:
angle 1 = angle2,
m∠1＝m∠2
m∠ 1 = x + 14,
m∠2 = y - 3
Since m∠1＝m∠2
Substitute the value of m∠1 and m∠2 in the above equation,
⇒ x＋14＝y－3
Rearrange the terms in the above equation and solve for y,
⇒ －y＝- 3－x－14
⇒ －y－17－x
⇒ y＝17＋x
Thus, the solution of the given angle of the equation is y＝17＋x

Answer:
A) 29
Step-by-step explanation:
DG = GJ
GJ = DG = 4x + 17
DJ = DG + GJ
11x + 25 = 4x + 17 + 4x + 17
11x + 25 = 4x + 4x + 17 + 17 {Combine like terms}
11x + 25 = 8x + 34
Subtract 25 from both sides
11x = 8x + 34 - 25
11x = 8x + 9
Subtract 8x from both sides
11x - 8x = 9
3x = 9
Divide both sides by 3
x = 9/3
x = 3
DG = 4x + 17
= 4*3 + 17
= 12 + 17
DG = 29
Answe]here g is apoint on dj sdj = dg + gj 11x + 25 = dg + 44x + 14 11x - 44x + 25 - 14 = dg - 33x + 11 = dg

What are nudibranch? Only some of the most colorful sea creatures on Earth! These marine mollusks boast a variety of
unique shapes and colors, and they live anywhere in the world's oceans, from the tropics to Antarctica. There are many
different types of nudibranchs, some no longer than an inch, and some as long as two feet! Some use toxic appendages
to defend themselves, while others use camouflage. Some even make their own chemicals to keep predators at bay.
Why do nudibranchs have these defenses? Because they are naked! Nudibranch means "naked gills," so named for
their soft bodies and their exposed gills, which sit atop their backs. While common to the ocean, these unusual creatures
can be spotted on underwater dives.
In 2-3 sentences, summarize the information in the paragraph.
Nudibranchs are a detachment of marine gastropods, close to the snails, but without shell and with a pronounced mantle.
Their secondary cutaneous gills are soft, unprotected outgrowths of integuments of various shapes and are located on the sides or on the dorsal side of the body; some species have no gills at all. They inhabit mainly warm seas and oceans. Some species are poisonous and have a bright color. All nudibranchs are hermaphrodites. They are very picky about their food.

Answer:
((down below))
Step-by-step explanation:
If A is the midpoint of Line Segment XY, then we can conclude that the length of XA = the length of AY. ((in other words, XA = AY))
Find XA
Insert equations // 2x = 10x - 8It's best to solve for "x." So we do this by flipping the equation (you can do this in any way you want, but this seemed easier) // 8 = 10x - 2x8 = 8x // Divide for x // x = 1Finding the Length of AY (Calculating Length)
Substitute x = 1 from XA // 10(1) - 8We get an answer of 2 ((this is the length of AY))Finding the Length of XA
Substitute x = 1 from XA // 2(1)We get an answer of 2 ((this is the length of XA)Finding the Length of XY
XA = AY // the length of XA is 2 (or 2 units, or whatever you are measuring in) and the length of AY is 2, then finding the length of XY means adding both lengths togetherXA = AY = 2 = 2 = 2 + 2 = 4 ((the length of XY is 4))
