Answer:

2.65

Step-by-step explanation:

Using a calculator's square root key, we get √7 = 2.64575....

To the nearest hundredth, that'd be √7 = 2.65.

Answer:

Answer

2x+3y=14,2x−3y=2

Adding :

2x+3y=14

2x−3y=2

__________

4x=16

x=4

∴xy=4×2

=8

2×4+3y=14

8+3y=14

3y=6

y=2

Step-by-step explanation:

here you go

Answer: The y-intercept is found by substituting known values for x and y in the equation and solving for b. the known values are (x,y) = (2,8.4) Equation of y = 4.2*x + b becomes 8.4 = 4.2*2 + b

Answer:

kiloliters

Step-by-step explanation:

The amount of water a family uses in a year is a large amount of water - more than the amount of water in a pool! This means kiloliters would be the best unit of measurement.

Answer:

3--1/-2-4=4/-6=2/-3

y=-2/3x+b

-2*-2/3=4/3

3-4/3=5/3

y=-2/3x+5/3

Step-by-step explanation:

Answer:

[tex]\displaystyle y=-\frac{2}{3}x+\frac{5}{3}[/tex]

Step-by-step explanation:

We want to find the equation of the line that passes through the two points:

(4, -1) and (-2, 3).

First, we will find the slope of the two points. So:

[tex]\displaystyle m=\frac{3-(-1)}{-2-4}=\frac{4}{-6}=-\frac{2}{3}[/tex]

Now, we will use the point-slope form given by:

[tex]y-y_1=m(x-x_1)[/tex]

Use either point. I'm going to use (4, -1). So, substitute:

[tex]\displaystyle y-(-1)=-\frac{2}{3}(x-(4))[/tex]

Simplify and distribute:

[tex]\displaystyle y+1=-\frac{2}{3}x+\frac{8}{3}[/tex]

Subtract 1 from both sides. Therefore:

[tex]\displaystyle y=-\frac{2}{3}x+\frac{5}{3}[/tex]

Answer: X is equal to -3

Step-by-step explanation: I isolated x and then divided both sides by x

Answer:

y = 3 cm

Step-by-step explanation:

We'll begin by calculating the value of x. This can be obtained as follow:

2x + 6 = 5x – 9 (opposite side of rectangle are equal)

2x + 6 = 5x – 9

Collect like terms

6 + 9 = 5x – 2x

15 = 3x

Divide both side by 3

x = 15 / 3

x = 5 cm

Next, we shall determine the length of the rectangle. This can be obtained as follow:

L = 2x + 6

x = 5 cm

L = 2(5) + 6

L = 10 + 6

L = 16 cm

Finally, we shall determine the value of y. This can be obtained as follow:

Length (L) = 16 cm

Width (W) = y =?

Area (A) = 48 cm²

A = L × W

48 = 16 × y

Divide both side by 16

y = 48 / 16

y = 3 cm

Answer: While there are plenty of quality options on the shelves that fall between the $15 and $30 range, “trendy” olive oils like Brightland and Fat Gold cost more, at $37 and $44.75, respectively. Some even have price tags in the three digits.

Hi there!

Let think about this...

-6.3-6.3=h

h+6.3=-6.3

negative plus positive is negative...

h=negative number..

6.3+6.3=12.6 add a negative point=-12.6

Final Result: -12.6

Answer:

Step-by-step explanation:

Let x be the total number of medals won by the Russians.

The way to do this is to add the ratios together

1 + 8 + 5 = 14

(5/14) x = 25

Multiply by 14

5*x = 25 * 14

5x = 350              

divide by 5

70

8/14 = x / 70

14x = 8 * 70

14x = 560

x = 560 / 14

x = 40

The USA won 40 medals.

1/14 = x / 70

14x = 70

x = 5

Canada Won 5 medals.

Check

Russia       Won 25 medals

Canada     Won   5 medals

USA           Won 40 medals

Total 70

Answer:

y = (x+2)²-2

Step-by-step explanation:

Use the vertex form y = a(x-h)²+k. Plug in the vertex for h and k. Solve for a and you will get 1 for that value. You can check your answers by plugging in both of those points to make sure.

Given:

Consider the given square is

[tex](2xy+5y)^2[/tex]

To find:

The value of given square by using the identities.

Solution:

We know that,

[tex](a+b)^2=a^2+2ab+b^2[/tex]            ...(i)

We have,

[tex](2xy+5y)^2[/tex]

Using the identity (i), we get

[tex](2xy+5y)^2=(2xy)^2+2(2xy)(5y)+(5y)^2[/tex]

[tex](2xy+5y)^2=4x^2y^2+20xy^2+25y^2[/tex]

Therefore, the value of given square expression is [tex]4x^2y^2+20xy^2+25y^2[/tex].

there isn't an answer since all the letters are different and you can't add or subtract or do anything to uncommon values. 3x+x = 4x but u can't do 3x +y because they're not in common

Answer:

D. 48

Step-by-step explanation:

In the experiment, 16/40 landed exactly on heads. If you do 16/40 * 3/3 = 48/120.

This means that you can estimate 48 of the next 120 trials have 2 coins showing heads.

My guess is % 1/400

Answer:

0.5 is 0.25% of 200.

Step-by-step explanation:

1 is 1/200 of 200.

Therefore, 0.5 is 1/400 of 200.

1/400 = 0.0025 = 0.25/100

Therefore, 0.5 is 0.25% of 200.
