I don’t know help. Please paying 80 points

Answer:

1st they should multiply 2 and 4 first because you need to fallow order of operations you will get 8 then you add the 1 getting you 9 finally you subtracted 12 and 9 getting 3 so NO THE STUDENTS WORK WAS NOT DONE CORRECTLY

Answer:

[tex] \sqrt{45} [/tex]

Step-by-step explanation:

(5,9) and (2,3)

then by distance formula

[tex]d = \sqrt{{(x1 - x2)}^{2} + {(y1 - y2)}^{2} } [/tex]

d²=3²+6²

d²=9+36

d²=45

[tex]d = \sqrt{45 } [/tex]

Answer:

You can use the intercepts to graph the line. The graph of 2x + 3y = 12 crosses the x-axis at (6, 0), so its x-intercept is 6. The graph of 2x + 3y = 12 crosses the y-axis at (0, 4), so its y-intercept is 4.

Step-by-step explanation:

Answer:

x = -6  y = 4

(-6,0)  (0,4)

Step-by-step explanation:

2x - 3y = -12

cancel out the y

2x - 3(0) = -12

2x = -12

divide both sides by 2

x = -6

2x - 3y = -12

cancel out the x

2(0) - 3y = -12

-3y = -12

divide both sides by -3

y = 4

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

10+5.50x=34+2.50x

-2.50x from each side

10+3x=34

-10 from each side

3x=24

divide both sides by 3

x=8

Answer:

x=1.4 or 21/15

Step-by-step explanation:

Answer:

x is equal to one and two fifths.

Step-by-step explanation:

Given:

12x - 15 = 6 - 3x

Let's start by noticing that every term in that equation is divisible by 3.  That means we can factor 3 out of it, giving us:

4x - 5 = 2 - x

Now we'll add x to both sides:

4x + x - 5 = 2 - x + x

5x - 5 = 2

An then we add 5 to both sides:

5x - 5 + 5 = 2 + 5

5x = 7

Finally, we can divide both sides by 5 to get the final answer:

5x ÷ 5 = 7 ÷ 5

x = 7/5

To put that in proper form it would be:

[tex]x = 1 \frac{2}{5}[/tex]

Answer:

Step-by-step explanation:

The  straight line equation is:

y = m*x  + b     Where m is the slope of the line and b the intercept with   y-axis, in our case y is the depth of the tank and x (time in lapsus of 3 hours).

The slope m  =  ( y₂ -  y₁ ) / (x₂ - x₁)

We have point  A ( 3 , 8 )  and point  B ( 6 , 7 )

m  = ( 6 - 3 ) / (7 - 8 )  m = -3

We see that  each 3 hours time-depth decreases  1 in.

Then   to find the depth at the beginning of x-axis

At  noon     12   tank was  9 inches, three hours before at 9 in the morning the depth was 10 inches and:

9  in the morning   10

6  in the morning   11

3  in the midnight   12

12 in the night         13

Then 13 is the intercept with y-axis

then the equation is:

h = - 3*x + 13

Note x is time in lapsus  of 3 hours

Answer:

Coincident

Step-by-step explanation:

Two lines that lie exactly on top of each other are called coincident.

[tex]4y+x=2[/tex] --------------(1)

is same as

[tex]8y+2x=4[/tex] -----------(2)

taking 2 common from equation (2)

[tex]4y+x=2[/tex]

which is same as equation (1)

The answer is A. [tex]\frac{(x-2)(x+6)}{x-6}[/tex].

Answer:

A. he sold the the car for 1350000

B. his cost price is 1500000

Step-by-step explanation:

A. 150000---> 10%

x-----> 90%

cross multiplication: x=150000×90/10=1350000

B. 10%( price) +90%(price)

1350000+150000=1500000

Answer:

[tex]\frac{21}{4}[/tex] quarts

12 days

Step-by-step explanation:

Given that:

Amount of water leaked in 4 days = 3 quarts

To find:

Number of quarts leaked in 1 week?

Number of days taken for the leakage of 9 quarts of water?

Solution:

We can simply use unitary method or the ratio to find the answers of the questions asked in the statement.

As per question statement:

Amount of water leaked in 4 days = 3 quarts

Dividing by 4 on both sides:

Amount of water leaked in 1 day = [tex]\frac{3}{4}[/tex] quarts

Multiplying by 7 on both sides:

Amount of water leaked in 7 days = [tex]\frac{3}{4}\times 7 = \frac{21}{4}[/tex] quarts

Number of days taken for the leakage of 3 quarts = 4 days

Multiplying by 3 on both sides:

Number of days taken for the leakage of 3 [tex]\times[/tex] 3 = 9 quarts = 4 [tex]\times[/tex] 3 = 12 days

Answer:

x = 8

Step-by-step explanation:

Given

- 4(- x + 8) = 0

- 4≠ 0, so

- x + 8 = 0 ( subtract 8 from both sides )

- x = - 8 ( multiply both sides by - 1 )

x = 8

Answer:

X=8
