Answer:

When p2 – 4p is subtracted from p2 + p – 6, the result is:

p2+p-6-(p2-4p)=p2+p-6-p2+4p=5p-6

To get p – 9, subtract from this result x:

5p-6-x=p-9

Solving for x:

5p-6-x+x-p+9=p-9+x-p+9

4p+3=x

x=4p+3

Answer:

1) When p2 – 4p is subtracted from p2 + p – 6, the result is 5p-6

2) To get p – 9, subtract from this result 4p+3

175 miles

Hi there !

4 gallons .......... 140 miles

5 gallons ...............x miles

x = 5×140/4 = 700/4 = 175 miles

Good luck !

Answer:

Length: 120cm, Width: 72cm

Step-by-step explanation:

Let x = length

Let 3x/5 = width

2x+2(3x/5)=384

2x+(6x/5)=384

16x/5=384

16x=1920

x=120cm

Substitute 120 for x in width

360/5 = width

width = 72cm

Answer:

Option 1

Step-by-step explanation:

look at the graph in bot cases y still positive in the upper part of the graph

only x moves from the right side to left side of the graph

Take one point A (2,2) to A'(-2,2)

from 2 to -2 (x-4=2-4=-2)

from 2 to 2 ( y still the same)

Answer:

The information with which the parabola is constructed is insufficient

Step-by-step explanation:

The vertex form of a quadratic equation is given as follows;

f(x) = a(x - h)² + k

The steps to draw the graph of a quadratic function given in vertex form, we are required to do the following;

1) Definition of the variables, (a, h and k) of the quadratic equation (given in vertex form)

The vertex of the quadratic equation in vertex form is (h, k)

2) Given that the vertex point is given, the vertex point is then plotted on the graph

3) Draw the parabola axis of symmetry that passes through the vertex point

4) Determine the direction to which the parabola opens from the sign of the variable a as follows;

i) When a is positive, the parabola opens upwards

ii) When a is negative, the parabola opens downwards

5) Determine if the parabola has x-intercepts and plot them

A parabola has x intercepts when;

i) The parabola opens downwards, that is, the variable, a, is negative and also the vertex (h, k) is above the x-axis or k is positive

ii) The parabola opens upwards, that is, the variable, a, is positive and also the vertex (h, k) is below the x-axis or k is negative

6)  Determine y-intercepts and plot them as follows;

At the y-intercept, x = 0, therefore;

f(x) = a(x - h)² + k

f(0) = a(0 - h)² + k = a·h² + k

6) If any additional points are required, they should plotted and then the graph of the function is then drawn making sure to be symmetrical about the vertex and to pass through all the plotted points.

Answer: 15 players.

Step-by-step explanation:

number of games played in the tournament = 105 games

nunber of games played by each player against another = 1 game each.

Solution:

Number if player who participated in the tournament.

if each player played a game against every other player, and they were 105 games played at the tournament.

n ( n – 1 ) /n = m

= n ( n – 1 ) 2 = 105

open the bracket

n^2 – n = 210

n^2 – n – 210 = 0

( n – 15 ) ( n + 14 ) = 0

n = 15

15 players Participated In the tournament.

Answer:

105 degrees

I can't see the question very well. I'm really upon this question please

Answer:

[tex]x = 6[/tex]

[tex]y = -7[/tex]

Step-by-step explanation:

We have the system of equations:

[tex]4x+2y=10\\x=y+13[/tex]

Let's solve by substituting. We know that [tex]x=y+13[/tex], so we can substitute [tex]y+13[/tex] in as [tex]x[/tex] in the equation [tex]4x+2y=10[/tex].

[tex]4(y+13) + 2y = 10[/tex]

Simplify this down so that we have [tex]y[/tex] on one side of the equation:

[tex]4y + 52 + 2y = 10\\\\6y + 52 = 10\\\\6y = -42\\\\y = -7[/tex]

Now that we know the value of [tex]y[/tex], we can substitute it in to the equation [tex]x = y+13[/tex] to find [tex]x[/tex].

[tex]x = -7+13\\\\x = 6[/tex]

Hope this helped!

Answer:  (6,-7)

Step-by-step explanation:

4x +2y = 10  

x = y + 13      Substitute the value of x into the first equation to solve for y.

4(y + 13) +2y = 10   apply the distributive property on the left side

4y + 52 + 2y = 10   Combine like terms on the left side

6y + 52 =  10    Subtract  52 from both sides

       -52     -52

6y = -42  

y= -7  

The value of y so input it into one of the equations to solve for x

4x + 2(-7) = 10  

4x - 14  =  10

       +14    +14

4x = 24

x= 6

Answer: It already tells you what DE= 60

Step-by-step explanation:

Since F is the midpoint of DE that means DF=FE

So create equation [tex]2x+6+2x+6=4x+12[/tex]

When DF and FE is added your answer should equal DE

So you write the equation [tex]4x+12=2x+36[/tex] to find x and once x is found substitute your answer for x

[tex]4x+12(-12)=2x+36(-12)[/tex] subtract 12 on both sides 36-12= 24

[tex]4x=2x+24[/tex] subtract 2x on both sides 4x-2x=2x

[tex]2x=24[/tex] divide 2 into both sides 24/2=12 x=12

[tex]4(12)+12=2(12)+36[/tex]  

4x12=48+12=60   2x12=24+36=60

AREA

To find the area of a parallelogram, you multiply the base by the height.

12(6)=72

The area is 72 square centimeters.

PERIMETER

The two diagonal sides are 8 cm and the two bases are 12 cm.

8+8+12+12=40

The perimeter is 40 cm.

Have a wonderful day! :D

Answer:

x=8.625

Step-by-step explanation:

ok so the lines mean absolute value so its actuall positive soyou get 3+8x+8=80

so add 3 and 8 to get 11+8x=80

subtract 11 to get 8x=69

then divide it by 8 so x is by itself

x=8.625 hope this helped :)

Answer:

x = 3 , x = -3

Step-by-step explanation:

3 | -8x | + 8 = 80

3 | -8x | = 72

Solve the negative and positive case:

Negative-

-3 ( -8x ) = 72

24x = 72

x = 3

Positive-

3 (-8x ) = 72

-24 = 72

-x = 3

x = -3

how to calculate slope-

(Y2 - Y1) / (X2 - X1)

Answer:

A

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 6, 3) and (x₂, y₂ ) = (3, - 9) ← 2 points on the line

m = [tex]\frac{-9-3}{3+6}[/tex] = [tex]\frac{-12}{9}[/tex] = - [tex]\frac{4}{3}[/tex] → A

Answer:

[tex]x=-3[/tex]

Step-by-step explanation:

[tex]9-2x=15[/tex]

Subtract 9 from both sides:

[tex]9-2x-9=15-9[/tex]

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

Divide both sides by -2:

[tex]\frac{-2x}{-2}=\frac{6}{-2}[/tex]

[tex]x=-3[/tex]

Answer:

It would be NEGATIVE because a positive number times a negative number, the answer is negative.
