Use the algebra tiles to help you solve the equation. 4x-2=10

Answer:

164 round = 160

your answer now can you please help me

Step-by-step explanation:

Given the domain of values D = {-3, -2, -1, 0, 1, 2, 3}

1) If the set of range is one less than the domain, the required range will be:

Range = {-4, -3, -2, -1, 0, 1, 2}

2) If the set of range is 2 more than the domain, the required range will be:

Range = {-1, 0, 1, 2, 3, 4, 5}

The table of values is given as:

x       y

-3  |  -1

-2  |   0

-1  |   1

0   |   2

1    |   3

2   |   4

3   |   5

2) For equation 1, we will use the coordinate points (0. -1) and (1, 0)

The equation in slope-intercept form is given as y = mx + b

m = 0-(-1)/1-0

m = 1/1 = 1

Since the y-intercept is at (0, -1), hence b = -1

Substitute the given value into the formula:

Recall that y = mx + b

y = 1x + (-1)

y = x - 1

Hence the equation 1 will be y = x - 1

For equation 2, we will use the coordinate points (-1, 1) and (0, 2)

The equation in slope-intercept form is given as y = mx + b

m = 2-1/0-(-1)

m = 1/1 = 1

Since the y-intercept is at (0, 2), hence b = 2

Substitute the given value into the formula:

Recall that y = mx + b

y = 1x + 2

y = x + 2

Hence the equation 2 will be y = x + 2

4) The graph of each equation on a different coordinate plane is attached.

Answer:

x = 2

Step-by-step explanation:

First, let's write out our equation:

[tex]2x-4=6-3x[/tex]

I want to isolate x on one side, so first, I'll add 4 to both sides to remove the -4 from next to 2x:

[tex]2x-4+4=6-3x+4\\2x=-3x + 10[/tex]

Notice that I combined like terms with the -4 and 4 (to get 0) and the 6 and 4 on the right side (to get 10). Next, I'll add 3x to both sides:

[tex]2x + 3x = -3x + 3x + 10[/tex]

And then I'll add like terms:

[tex]5x=10[/tex]

Now, all we have to do is divide both sides by 5:

[tex]5x/5=10/5\\x=2[/tex]

And there's our answer. Hopefully that's helpful! :)

Answer:

12, 1260

Step-by-step explanation:

Andrew paid $10 for a burger. The burger had a discount of 20%. This means that the $10 is 80% of the original price.

100% - 80% = 20%

To find the original price, you can multiply by 120%

10 * 120% = 12

Abby Matthews needs to mark up a refrigerator that costs $900 to 140% of the original price. To do this, you can directly multiply.

900 * 140% = 1260

The area of the room is equal to 100 m² and perimeter is 40m

The area is the space covered by the object. It is the region occupied by any shape. While measuring the area of a square, we consider only the length of its side. All sides of a square are equal; hence, its area is equal to the square of the side and the perimeter of a square = 4 ×  side units.

Given here: Unit rate of painting per meter square=15 and it cost 1500 in total

Thus Area = 1500/15

                  =100 m²

Then a²=100 and a=10

∴Perimeter of the square room is = 4×10

                                                        =40 m

Hence, The area of the room is equal to 100 m² and perimeter is 40m

Answer:

2√6

Step-by-step explanation:

1. First, let's solve for the base of the triangle with the help of the Pythagorean Theorem (a^2 + b^2 = c^2).

2. Now, let's find the factors of 24 and see which one is a perfect square:

Therefore, the answer is 2√6.

Answer:

[tex]b=2\sqrt{6}[/tex]

Step-by-step explanation:

The triangle shown is a right triangle.

Because this triangle is a right triangle, we can use they Pythagorean theorem to find the missing side length.

Pythagorean theorem : [tex]a^2+b^2=c^2[/tex]

where a and b = length of legs and c = hypotenuse ( longest side )

we have the hypotenuse ( 7 ) and a leg (5) and need to find the other leg.

So we know that a = 5 and c = 7 and we need to find b

Using the Pythagorean theorem:

[tex]a^2+b^2=c^2[/tex]

a = 5 and c = 7

[tex](5)^2+b^2=(7)^2[/tex]

simplify exponents 5² = 25 and 7² = 49

[tex]25+b^2=49[/tex]

subtract 25 from both sides

[tex]b^2=24[/tex]

take the square root of both sides

[tex]b=\sqrt{24}[/tex]

simplify radical

[tex]b=2\sqrt{6}[/tex]

Answer:

y=65x+30

Step-by-step explanation:

Using y=mx+b, we see that they need 65 dollars per hour, and since x represents the # of hours, we put 65 there as our "slope." Then 30 is the starting amount, or our y-intercept

Wednesday reported -20 compared to the other days recording -5, 15, and 20 degrees. In this case, Wednesday had the coldest temperature.

Answer: Wednesday

Step-by-step explanation: Think of it like this; all temperatures are cold for us human beings. The question is being asked which days did Elizabeth record the lowest (coldest) temperature.

You can put this figures into a number line. Any number going to the right of a number line is an increase. So Monday and Tuesday can be eliminated. Any number going the left of a number line is decreasing. - 5 is very cold but -20 is colder than -5. Therefore, the lowest (coldest) temperature is -20 which was Wednesday,

Ok done. Thank to me :>

Step-by-step explanation:

Annie = x

Brianna = y

Carly = z

Now,

x + y + z = 105 ...(1)

Carly has sold ten more than three times Brianna's sales.

z = 10 + 3y ...(2)

Brianna sold five more than Annie.

y = 5 + x ...(3)

Now,

z = 10 + 3y

z = 10 + 3(5 + x)

z = 10 + 15 + 3x

z = 25 + 3x

Now,

x + y + z = 105

x + (5 + x) + 25 + 3x = 105

5x + 30 = 105

5x = 105 - 30

5x = 75

5x/5 = 75/5

x = 15

So,

y = 5 + x

y = 5 + 15

y = 20

Now,

z = 25 + 3x

z = 25 + 3(15)

z = 25 + 45

z = 70

Thus,

Annie Sold 15 boxes

Brianna Sold 20 boxes

Carly Sold 70 boxes

Below.

Step-by-step explanation:

Using Pythagoras theorem, let's find y.

=> y² = 3² + 3²

=> y² = 9 + 9
