Answer:

The solution to the system of equations will be:

[tex]x=9,\:y=6[/tex]

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}2x-9y=-36\\ -14x+18y=-18\end{bmatrix}[/tex]

Multiply 2x-9y=-36 by 7

[tex]14x-63y=-252[/tex]

so the system of equations becomes

[tex]\begin{bmatrix}14x-63y=-252\\ -14x+18y=-18\end{bmatrix}[/tex]

Adding both equations

[tex]-14x+18y=-18[/tex]

[tex]+[/tex]

[tex]\underline{14x-63y=-252}[/tex]

[tex]-45y=-270[/tex]

solve -45y = -270 for y

[tex]-45y=-270[/tex]

divide both sides by -45

[tex]\frac{-45y}{-45}=\frac{-270}{-45}[/tex]

Simplify

[tex]y=6[/tex]

For 14x-63y = -270 plug in y = 6

[tex]14x-63\cdot \:6=-252[/tex]

[tex]14x-378=-252[/tex]

Add 378 to both sides

[tex]14x-378+378=-252+378[/tex]

Simplify

[tex]14x=126[/tex]

Divide both sides by 14

[tex]\frac{14x}{14}=\frac{126}{14}[/tex]

Simplify

[tex]x=9[/tex]

Therefore, the solution to the system of equations will be:

[tex]x=9,\:y=6[/tex]

Answer:

x=12

Step-by-step explanation:

Subtract 2 from both sides

Subtract 2 from 12 to get 10

Divide both side by 5

Finally,divide 10 by 5 to get 2

5(2)+2=12

+t+ = traveler's speed in ft/sec

+w+ = walkway's speed in ft/sec

given:

+t+-+w+=+2+

+t+%2B+w+=+6+

-------------

Add the equations

+2t+=+8+

+t+=+4+

and

+t+%2B+w+=+6+

+4+%2B+w+=+6+

+w+=+2+

The traveler's speed off the walkway is 4 ft/sec

The speed of the moving walkway is 2 ft/sec

Answer:

3x+4y=-36

x= -4/3y-12

-2x+4y=-16

x= 2y+8

Answer:

80 pages

Step-by-step explanation:

Point slope Equation is :

y = mx + c

In the above question

y = 310 pages

x = number of days = 10 days

m= 23 pages per day

c = ?? Unknown

c = y - mx

c = 310 - 23 × 10

c = 310 - 230

c = 80 pages

She will still have 80 pages left to read after 10 days

Answer:

Answer:

3x

Step-by-step explanation:

The GCF would be 3x, if you took out 3x from those numbers you'd be left with x^2, 2x, and 5, which can't be reduced any further.

Answer: 116

Step-by-step explanation: simply divide 8 into 928

Answer:

=116

Debby would be able to buy 116 cokes from the coke machine.

Answer:

Infinite Many Solutions

Step-by-step explanation:

If I am correct the two lines are overlapping each other in more than one place so that means there are infinitely many solutions. Also, there can be no " two solutions" for this type of equation. There can only be one solution, no solution, or infinitely many solutions.

Answer:

176 of 12% vinegar

44 of 7% vinegar

Step-by-step explanation:

Percentage vinegar required = 11%

Volume = 220 mL

First brand % = 7%

Second brand % = 12%

Let p = volume of 12% vinegar material

Mixture :

0.12p + 0.07(220 - p) = 220 * 0.11

0.12p + 15.4 - 0.07p = 24.2

0.05p = 8.8

p = 8.8 / 0.05

p = 176

176 of 12% vinegar and

220 - 176 = 44

44 of 7% vinegar

Answer:

0 = 0 miles

1 = 1.5 miles

2 = 3 miles

3 = 4.5 miles

4 = 6 miles

5 = 7.5 miles

Step-by-step explanation:

multiply each hour by 1.5

If a garden snail travels 1.5 miles per hour, then when 0 hours pass, it would have travelled 0 miles (no time has passed).

After 1 hour, it would have travelled 1.5 miles.

After 2 hours, it would have travelled 3 miles (1.5 miles × 2 hours).

After 3 hours, it would have travelled 4.5 miles (1.5 miles × 3 hours).

After 4 hours, it would have travelled 6 miles (1.5 miles × 4 hours).

After 5 hours, it would have travelled 7.5 miles (1.5 miles × 5 hours).

I hope this helps!

Answer:

Slope: -1

Point-Slope Form: y - 2 = -1 (x - (-2))

Step-by-step explanation:

Answer: y-2=-1(x+2)

Step-by-step explanation: use whichever points you want I’m using (-2,2)

Find slope: y2-y1/x2-x1 so 2+2/-2-2 = 4/-4 = -1

Plug in these into y-y1= m(x-x1)

y-2= -1(x+2)

Answer:

first choice

Step-by-step explanation:

a^2 + b^2 = c^2

a^2 + 10^2 = 15^2

a^2 + 100 = 225

       - 100    -100

a^2 = 125

square 125

a = 11.18
