what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.

Answer:
B, one
Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

1/8 1/4 3/8 1/2 5/8 3/4
Step-by-step explanation:
First, we must organize the order of the numbers from least to greatest. This will keep the data organized, (and maybe get you extra points). So, let's convert all the fractions so that they will have a denominator of 8.
1/4 = 2/8, 1/2 = 4/8, 3/4 = 6/8.
Now in order we get: 1/8, 1/4, 3/8, 1/2, 5/8, 3/4.
Second, count the number of each fraction that occurs in the data set. Now, put them next to the fractions.
1/8 has 2, 1/4 has 3, 3/8 has 4, 1/2 has 3, 5/8 has 1, 3/4 has 2.
Third, let's put together all the data in to the line plot. First, draw a horizontal line. Then, put dashes intersecting the horizontal line, 6 of them. Beneath the dashes, write the fractions from least to greatest. Above the dashes, draw the number of X's to represent the number of occurrences on each fraction.

Banana Cupcakes
makes 10 cupcakes
1 cup granulated sugar
cup vegetable oil
1 large egg
4 tablespoons sour cream
2 medium-sized ripe bananas, mashed
1 cups all-purpose flour
1 teaspoon baking soda
teaspoon salt
1 teaspoon vanilla extract
pinch of nutmeg
You will use the recipe above to answer the following questions:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?

The graph represents a relation where x represents the independent variable and y represents the dependent variable. a coordinate plane with points at negative 5 comma 1, negative 2 comma 0, 0 comma 2, 1 comma negative 2, 1 comma 3, and 5 comma 1 Is the relation a function? Explain. No, because for each input there is not exactly one output No, because for each output there is not exactly one input Yes, because for each input there is exactly one output Yes, because for each output there is exactly one input
No the given relation is not a function because for one input we are getting two different values of output which negates the definition of the function.
A relation is said to be a function when each and every element of domain has a unique and distinct image means we will get only one output per input.So
statement 1: No, because for each input there is not exactly one output . This is true.statement 2: No, because for each output there is not exactly one input. This is false.statement 3:Yes, because for each input there is exactly one output .This is false.statement 4:Yes, because for each output there is exactly one input.This is also false.Hence the given relation is not a function.

The given relation is not a function because for each input (x-value), there is not exactly one output (y-value).
In a function, each input (x-value) should have only one corresponding output (y-value). However, in this relation, the input value of 1 has two different output values: -2 and 3. Therefore, it violates the definition of a function.
To illustrate this, let's look at the points (-2, 0), (1, -2), and (1, 3). The x-value of 1 appears twice in the relation, but it has two different y-values associated with it. This means that for the input value of 1, there is not exactly one output value, which is why the given relation is not a function.
In conclusion, the relation is not a function because for each input there is not exactly one output.

Answer
B 399.4 cm^2
Pls mark brainliest.
pls help me man, math is so hard
Answer:
199 cm^2
Step-by-step explanation:
1. First, we have to find the radius. Divide the circumference by pi (3.14): 50/3.14=15.92. This gives us the diameter.
2. Divide the diameter by 2: 15.92/2=7.96. This is the radius.
3. Use the formula for the area of a circle. Area=3.14*7.96^2.
4. Solve this equation and you get the answer: About 199 cm^2
Answer:199
Step-by-step explanation:
the formula for the area of a circle is \(\pi r^{2}\) (pi *radiusto the power of 2)
so the 50 metered wire is the circumference of the circle
to get the area of the circle you need the radius
to get the radius you need to divide 50 by 3.14 (\(\pi\)), that equals to 15.923566879 this is the diameter to get the radius you need to divide it by 2 . radius =7.961783439
formula for area =\(\pi r^{2}\)
\(\pi\)=3.14
3.14ˣ7.961783439ˣ7.961783439=199.044585975
round it to nearest number = 199
Use the table shown in the image! 1. Which equation expresses “y” in terms of “x”? A. y=17x B. y=25x C. x=51y D. x=85y 2. What is the charge for renting a machine for 3.5 hours? A. $51.50 B. $59.50 C. $65.50 D. $86.50
Please include all work!
Answer: 1. A. y=17x
2. $59.50
Step-by-step explanation:
1. In the table , it can be seen that as x increases y increases with the proportionality constant k = \(\dfrac{y}{x}=\dfrac{51}{3}=\dfrac{85}{5}=\dfrac{119}{7}=17\),.
Equation of direct variation between x and y : \(y=kx\)
Put k= 17 , we get
\(y=17x\) , which is the required equation.
So correct option is "A".
2. To find : The charge for renting a machine for 3.5 hours.
Put x= 3.5 in above equation , we get
\(y=17(3.5)=59.5\)
Hence, the charge for renting a machine for 3.5 hours is $59.50.
So correct option is "B".
whats the surface area?
Answer:
1108 in²
Step-by-step explanation:
You want the total surface area of the pentagonal prism shown.
Base areaThe area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...
A = LW +1/2bh
A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches
Lateral areaThe lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.
LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches
Total areaThe total surface area of the figure is the sum of the two base areas and the lateral area:
SA = 2(114 in²) +880 in² = 1108 in²
The surface area of the composite figure is 1108 in².
