Answer:

-12

Step-by-step explanation:

3(x-4)+2x^2

when x =5 , sub 5 into x

3(5-4)+2(5)-(5)^2

=15-12+10-25

=-12

Answer:

Step-by-step explanation:

3(x-4)+2x-x^2 first you should eliminate the parentheses

3x-12+2x-x^2 now replace x for 5

3(5)-12+2(5)-(5)^2

15-12+10-25

Answer:

The right answer is [tex]\frac{2}{9}[/tex].

Step-by-step explanation:

To multiply two fractions we multiply numerator by numerator and denominator by denominator. In this case:

[tex]\frac{-1}{4} x\frac{-8}{9} = \frac{8}{36}[/tex]

Notice that both numerator and denominator are divisible by 4. Dividing both by 4 we get [tex]\frac{8}{36} = \frac{2}{9}[/tex]  

First, 12.6 times 9 is 113.4. So withouth the space, that is how long the busses are. Then you do 2meters times 8 is 16 meters between the busses. 113.4+16 equals 129.4, the final answer.

Answer:  The total length from the front of the first bus to the end of the last bus is 129.4 meters.

Step-by-step explanation:

Hi, to answer this question we have to multiply:

The number of buses by the length of each one

The number of spaces between buses by the length of each space.

Since there is no space in front of the first bus and behind the last bus, there are 8 spaces in between.

Answer:

x = - 3 is extraneous

Step-by-step explanation:

Given

[tex]\sqrt{x+7}[/tex] - 1 = x  ( add 1 to both sides )

[tex]\sqrt{x+7}[/tex] = x + 1 ( square both sides )

x + 7 = (x + 1)² ← distribute right side

x + 7 = x² + 2x + 1 ( subtract x + 7 from both sides )

0 = x² + x - 6 ← in standard form

0 = (x + 3)(x - 2) ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 2 = 0 ⇒ x = 2

As a check

Substitute these values into the equation and if both sides are equal then they are the solutions.

x = - 3 : [tex]\sqrt{-3+7}[/tex] - 1 = [tex]\sqrt{4}[/tex] - 1 = 2 - 1 = 1 ≠ - 3

x = 2 : [tex]\sqrt{2+7}[/tex] - 1  = [tex]\sqrt{9}[/tex] - 1 = 3 - 1 = 2

x = 2 is a solution and x = - 3 is extraneous

Answer:

60 cm

Step-by-step explanation:

Parallelogram ABCD is shown in attached diagram. The diagonals of the parallelogram bisect each other, so

AE = EC

BE = ED

Ib DE = 3y + 6 cm, BE = 5y - 10 cm, then

[tex]3y+6=5y-10\\ \\3y-5y=-10-6\\ \\-2y=-16\\ \\2y=16\\ \\y=8\ cm[/tex]

Now, EC = 2y + 4, so

[tex]EC=2\cdot 8+4=16+4=20\ cm[/tex]

Since AE = EC, then AE = 20 cm

The brace that connects points B and D has the length

[tex]BD=BE+ED=3y+6+5y-10=8y-4=8\cdot 8-4=64-4=60\ cm[/tex]

a = 7/2

Step-by-step explanation:

2x - y - 5 = 0

2x = y + 5

y = 2x - 5

m = -1/2

y - 5 = -1/2(x - (-2))

y - 5 = -1/2(x + 2)

y - 5 = -x/2 - 1

y = -x/2 + 4

a = -1/2 + 4

a = 7/2

Answer:

x = 10

Step-by-step explanation:

collect like terms, so add 5 to both sides: 2x = 20

divide both sides by 2 to get the value of x: x = 10

Answer:

x=10

Step-by-step explanation:

first, add 5 to both sides. the -5 and +5 cancel out, and 15 + 6 is 20. 2x=20. now divide 2 on both sides. the 2s cancel out and 20/2 is 10, so x=10.

Answer:

A sentence that has  or is conveying  a question.

Step-by-step explanation:

Answer:

Step-by-step explanation:

sentence that asks a question.

Answer:

it will take 80 minutes

Step-by-step explanation:

Total no.of rows=10

Time taken to plant 3 rows = 24 min

So,find time taken for planting 1 row

which is =24/3=8min

total time taken to plant 10 rows=8×10=80min

so it takes 80 min to plant 10 rows

It takes 8 minutes to plant one row of the garden and therefore to plant all 10 rows, it will take a total of 80 minutes.

This question is asking for the total time it would take to plant a garden with 10 rows of vegetables if it took 24 minutes to plant the first 3 rows. First, we need to understand how long it takes to plant one row. To find this out, we divide the total amount of time (24 minutes) by the number of rows planted in that time (3 rows). This gives us how long it takes to plant one row: 24 minutes ÷ 3 rows = 8 minutes per row. Now that we know this, we can work out how long it would take to plant all 10 rows. We do this by multiplying the time it takes to plant one row (8 minutes) by the total number of rows we need to plant (10 rows). This gives us the total time: 8 minutes per row x 10 rows = 80 minutes. So, it would take 80 minutes to plant all 10 rows of the garden.

Answer:

d=1/2

Step-by-step explanation:

9(8d-5)+13=12d-2

1) Use the distributive property:

72d-45+13=12d-2

2) Combine alike terms:

72d-32=12d-2

3) Add 32 to both sides:

72d=12d+30

4) Subtract 12d on both sides:

60d=30

5) Divide both sides by 60:

d=30/60

6) Simplify 30/60 to 1/2

To solve the system of equations y = 2x - 5 and y = x² - 5, use algebraic methods such as factoring or the quadratic formula to find the x-values. Then plug these values back into one of the original equations to find the corresponding y-values. The solutions to the system of equations are (5, 5) and (-2, -9).

To solve the system of equations y = 2x - 5 and y = x² - 5, we can set the two equations equal to each other since they both equal y. This gives us the quadratic equation x² - 2x - 10 = 0. We can solve this quadratic equation by factoring, completing the square, or using the quadratic formula.

Factoring the quadratic equation, we get (x - 5)(x + 2) = 0. This means that x - 5 = 0 or x + 2 = 0. Solving these two equations gives us x = 5 or x = -2. Substituting these values back into either of the original equations, we can find the corresponding y-values. For x = 5, y = 2(5) - 5 = 5. For x = -2, y = 2(-2) - 5 = -9. Therefore, the solutions to the system of equations are (5, 5) and (-2, -9).

Answer:

For points :  (2, 12) and (6, 11)

, option A. is correct.

For points : (6, –1) and (–3, –1), option B. is correct

Step-by-step explanation:

We are given points in both the questions and we need to find the slope.

Slope refers to steepness of curve .It is basically change in y with change in x.

For two points [tex]P\left ( x_1,y_1 \right )\,,\,Q\left ( x_2,y_2 \right )[/tex], slope of line PQ is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

For points : (2, 12) and (6, 11)

Let [tex]P\left ( x_1,y_1 \right )=(2, 12)\,,\,Q\left ( x_2,y_2 \right )=(6, 11)[/tex],

Slope is [tex]\frac{11-12}{6-2}=\frac{-1}{4}[/tex] i.e, - 1 over 4

So, option A. is correct.

For points : (6, –1) and (–3, –1)

Let [tex]P\left ( x_1,y_1 \right )=(6, -1)\,,\,Q\left ( x_2,y_2 \right )=(-3, -1)[/tex]

Slope is [tex]\frac{-1+1}{-3-6}=\frac{0}{-9}=0[/tex]

So, option B. is correct

The required slope of the lines with the given coordinates are as follow,

For first line option A. -1/4

For second line option B.0.

For the first set of coordinates of the line,

Points  are (2, 12) and (6, 11)

let (x₁ , y₁ ) = (2, 12 )

( x₂ , y₂ ) = (6, 11 )

Slope of the line for the two coordinates (x₁ , y₁ ) = (2, 12 ) and

( x₂ , y₂ ) = (6, 11 ) is equal to

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substitute the value ,

m = ( 11 - 12 ) / ( 6 - 2 )

   = -1 / 4

For the second set of coordinates of the line,

Points  are (6, -1) and (-3, -1)

let (x₁ , y₁ ) = (6, -1 )

( x₂ , y₂ ) = (-3, -1 )

Slope of the line for the two coordinates (x₁ , y₁ ) = (6, -1 ) and

( x₂ , y₂ ) = (-3, -1 ) is equal to

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substitute the value ,

m = ( -1 - (-1) ) / ( -3 - 6 )

   =0 / -9

   = 0

Therefore, slope of the lines are option A. -1/4 and option B.0.
