Answer:
3(7-2y)=9
Because there is no symbol between the 3 and the "(" we can tell that it wants you to multiply.
With the distributive property you must distribute the 3 within (7-2y)
To that you would multiply 7 by 3, and multiply -2y by 3. This would get you:
21-6y=9
To get y you must isolate it, the first step to isolate it is remove the number with no "y" next to it. Which is "21" Also for further problems your way, You should add/subtract/divide/multiple the number that does not have the same or even a variable as the variable you are trying to find to the other side.
In this case it would be subtracting 21 from the left side and subtracting it to the right side which would give us: 6y=-12
(Because there was already a number with no variable: "9" you will subtract 21 from 9 which is why you get -12).
Next you will further isolate the y by removing the -6. "-6y" means -6 multiplied by y. So you will divide -6 from the left side AND the right side.
-6y ÷ -6 = y ; -12 ÷ -6 = 2
y=2
More tips: When you are moving something to the other side always do the opposite to remove it from one side and move it to the other. Example: -12 + y = 5
You want to move the -12 to the right side. So you need to remove "-12" from the left side by ADDING 12 because -12 + 12 = 0.
Now you simply add it to the right.
Another example: 4y = 8
Because 4y is multiplication (4 times y) you must divide it from each side to isolate the y! : y=2
If you divide a number from the left side, you must also divide it from the right side. If you add a number on the left side, you must also add it on the right side. Same goes for subtraction and multiplication. Think like that!

8x2 - 6x + 3 – 2x – 10x?
Answer:
8[tex]x^{2}[/tex] + 3 + -6x
Step-by-step explanation:
First we need to find the like terms so that we could add them. In this case the like terms are,
1. 6x , -2x , -10x
So, these are the only terms that we can add in this expression.
Hence,
=> 8[tex]x^{2}[/tex] + 3 + (6x - 2x - 10x)
=> 8[tex]x^{2}[/tex] + 3 + -6x
And this is as simple as this expression can go until we find the value of "x" which is not yet told.

The equation of the parabola that represents the given graph is y = 3x².
The correct option is B.
What is a parabola?A plane curve produced by a moving point such that its separation from a fixed point equals that of a fixed line is a parabola.
If the vertex of the parabola is at (0, 0), then the equation of the parabola has the form:
y = a x²
where "a" is a constant that determines the shape of the parabola. We need to find the value of "a" using the fact that the parabola passes through the point (1, 3).
Plugging in the coordinates of the passing point (1, 3), we get:
3 = a (1)²
3 = a
Therefore, the value of "a" is 5.
Hence, the equation of the parabola is:
y = 3x²

The temperature at 6.00 am was - 12 the temperature increased by 1/2 each hour for 6 hours what was the temperature in degrees Fahrenheit at noon
Answer: -9 degrees Fahrenheit
Step-by-step explanation:
Given: Temperature at 6:00 AM = -12 degrees Fahrenheit
Temperature increased each hour = [tex]\dfrac12[/tex] degrees Fahrenheit
Temperature increase in 6 hours = [tex]6\times\dfrac12=3\text{ degrees Fahrenheit}[/tex]
Temperature at noon = Temperature at 6:00 AM+Temperature increase in 6 hours
= -12+3 degrees Fahrenheit
= -9 degrees Fahrenheit
Hence, the temperature in degrees Fahrenheit at noon= -9 degrees Fahrenheit

Answer:
Area = 144 inches2
or
Area = 1 feet2
Steps:
1.5 feet = 18 inches
Area = l × w
= 8 × 18
= 144 inches2
or
8 inches = 0.66666666666667 feet
Area = l × w
= 0.66666666666667 × 1.5

50 ml of water is poured into a beaker. 50 ml of another liquid is poured into the same beaker. The beaker is left undisturbed for some time. After some time, it is observed that the liquid forms a clear layer on top of water. If the density of water is 1 g/cc, what could be the density of the second liquid?
Answer:
Well if you combined 50 ml to a beaker that already had 50 ml of water in it total you have 100 ml of water. The density of the second liquid would be the same as the first beaker but sense they are combined it would be 2 g/cc.

How can an area model help you set
up an equation for a problem situation?
Answer: In mathematics, an area model is a rectangular diagram or model used for multiplication and division problems, in which the or the and define the length and width of the rectangle.
We can break one large of the rectangle into several smaller boxes, using number bonds, to make the calculation easier. Then we add to get the area of the whole, which is the or quotient.
Step-by-step explanation:
For example, you can find the product 23 × 37 by finding the area of a rectangle with a width of 23 and a length of 37: Of course, there is little gained if you simply multiply 23 × 37! What makes the area model useful is that area is a conserved quantity.

solve for x -1/2x + 1/3 > 3/5
Answer:
x > 8/15
Step-by-step explanation:
x -1/2x + 1/3 > 3/5
Combine like terms
2/2x - 1/2x +1/3 > 3/5
1/2x + 1/3 > 3/5
Subtract 1/3 from each side
1/2x + 1/3 -1/3 > 3/5 -1/3
1/2x > 3/5 -1/3
Get a common denominator
1/2x > 9/15 - 5/15
1/2x > 4/15
Multiply each side by 2
2 * 1/2x > 4/15 * 2
x > 8/15

Answer:
Ok if you look at the figure, it is a vertical angle. This means that the angle opposite to each other is congruent.
m<1 is congruent to m<3
m<2 is congruent to m<4
m<3 is 60⁰ and is congruent to m<1. This means that m<1 is 60⁰. m<4 is 30⁰ and is congruent to m<2. This means that m<2 is 30⁰.
m<1 = 60⁰
m<2 = 30⁰
m<3 = 60⁰
m<4 = 30⁰

The function below shows the cost of a hamburger with different numbers of toppings (t). f(t) = 1.90 + 1.40t What is the y-intercept, and what does it mean?
Answer:
[tex]1.9[/tex]
the cost of the hamburger will be [tex]\$1.9[/tex] if no toppings are added.
Step-by-step explanation:
The function is
[tex]f(t)=1.9+1.4t[/tex]
Let cost of toppings be [tex]y[/tex]
[tex]y=1.9+1.4t[/tex]
The y-intercept of a function is the value of the function when [tex]x=0[/tex]. Here number of toppings [tex]t=0[/tex].
So, the intercept of the function is [tex]1.9[/tex]
This means the cost of the hamburger will be [tex]\$1.9[/tex] if no toppings are added.
