Answer:

Multiply the first equation by 5 and the second equation by 2. Then add.

Multiply the first equation by 2 and the second equation by 5, then subtract.

Step-by-step explanation:

Given

[tex]- 2x + 5y = -15[/tex]

[tex]5x + 2y = -6[/tex]

Required

Steps to solve using elimination method

From the list of given options, option 2 and 3 are correct

This is shown below

Option 2

Multiply the first equation by 5

[tex]5(- 2x + 5y = -15)[/tex]

[tex]-10x + 25y = -75[/tex]

Multiply the second equation by 2.

[tex]2(5x + 2y = -6)[/tex]

[tex]10x + 4y = -12[/tex]

Add

[tex](-10x + 25y = -75) + (10x + 4y = -12)[/tex]

[tex]-10x + 10x + 25y +4y = -75 - 12[/tex]

[tex]29y = -87[/tex]

Notice that x has been eliminated

Option 3

Multiply the first equation by 2

[tex]2(- 2x + 5y = -15)[/tex]

[tex]-4x + 10y = -30[/tex]

Multiply the second equation by 5

[tex]5(5x + 2y = -6)[/tex]

[tex]25x + 10y = -30[/tex]

Subtract.

[tex](-4x + 10y = -30) - (25x + 10y = -30)[/tex]

[tex]-4x + 25x + 10y - 10y= -30 +30[/tex]

[tex]21x = 0[/tex]

Notice that y has been eliminated

Answer:

x = 18

Step-by-step explanation:

subtract 5 from both sides of the equation

2/3x=12

then multiply both sides by 3/2

x = 18

Answer:

18

Step-by-step explanation:

5 +2/3x =17 /×3

15 +2x =51

2x=51 - 15

2x=36

x=36 :2

x=18

Step-by-step explanation:

It dawned on me that if the coefficient of the x term is even, completing the square is much easier as can be seen here. The quadratic formula is simply completing the square as a compact expression, but when the coefficient of the x term is even, completing the square just seems cleaner.

Answer:

yes the answer is x = -2

Step-by-step explanation:

Answejust divide x on both terms and you left with 4x^2+3x then simple take a derivative which is 8x+3

Step-by-step explanation:

Answer:

1: 3 and 4      7:4     13: 0.3

2: 2 and 3     8: 6   14: 0.7

3: 7 and 8     9: 2   15: 0.6

4: 2 and 3    10: 9   16: 1.6

5: 8 and 9    11: 8    17: 1.4

6: 4 and 5    12: 15  18: 1.9

Step-by-step explanation:

Answer:

Step-by-step explanation:

Distribute 2/5 through the parentheses

2/5x-4/5=-1

multiply both sides by 5

2x-4=-5

move the constant to the right and change the sign

2x=-5+4

add the sum

2x=-1

divide both sides by 2

x=-1/2

Answer:X + Y ≥ 4

$2.20X + $2.95Y ≤ $10.00

Strawberries cost $2.20 per pound

Raspberries cost $2.95 per pound

Jada only has $10.00 to spend

She wants to buy at least 4 pounds

Assumption: She buys X pounds of strawberries and Y pounds of raspberries.

Solution:

Number of pounds can't be less than 4

i.e X + Y ≥ 4

The cost of buying strawberries and raspberries has to be $10.00 or less than $10.00

i.e $2.20X + $2.95Y ≤ $10.00

So the system of equations is;

X + Y ≥ 4

$2.20X + $2.95Y ≤ $10.00

Answer:

vertex = (- 3, - 8 )

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

f(x) = - 4(x + 3)² - 8 ← is in vertex form

with (h, k) = (- 3, - 8 ) ← vertex

Answer:

Answer is D.

Step-by-step explanation:

(x – 4)(x + 5)

= x(x + 5) -4(x + 5)

= x2 + 5x – 4x – 20

= x2 + x - 20

Answer:

50 degrees and 40 degrees

Step-by-step explanation:

50 degrees and 40 degrees

complimentary = add up to 90 degrees

5:4:9

50:40:90

Answer:

50° and 40°

Step-by-step explanation:

Complementary angles sum to 90°

sum the parts of the ratio, 5 + 5 = 9 parts

divide 90 by 9 for the value of one part of the ratio

90° ÷ 9 = 10° ← value of 1 part of the ratio, thus

5 parts = 5 × 10° = 50°

4 parts = 4 × 10° = 40°

The 2 angles are 50° and 40°

Answer:

y = 13x

Step-by-step explanation:

If "y" represents how much he earns total

and "x" represents the number of games sold

then the equation is [tex]y=65\frac{x}{5}[/tex]

which can be simplified to [tex]y = 13x[/tex]

Answer:

[tex]-\frac{11}{12}[/tex]

Step-by-step explanation:

Step 1- Add.

[tex]\frac{\frac{5}{8} +\frac{3}{4} }{\frac{-2}{3}-\frac{5}{6} }[/tex]  = [tex]\frac{\frac{11}{8} }{\frac{-3}{2} }[/tex]

Step 2- Divide and rewrite.

[tex]-\frac{\frac{11}{8} }{\frac{3}{2} }[/tex]  = [tex]-\frac{11}{12}[/tex]

Answer:

Step-by-step explanation:

Simplifying

6(2x + -6) = -7(-2x + 4)

Reorder the terms:

6(-6 + 2x) = -7(-2x + 4)

(-6 * 6 + 2x * 6) = -7(-2x + 4)

(-36 + 12x) = -7(-2x + 4)

Reorder the terms:

-36 + 12x = -7(4 + -2x)

-36 + 12x = (4 * -7 + -2x * -7)

-36 + 12x = (-28 + 14x)

Solving

-36 + 12x = -28 + 14x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-14x' to each side of the equation.

-36 + 12x + -14x = -28 + 14x + -14x

Combine like terms: 12x + -14x = -2x

-36 + -2x = -28 + 14x + -14x

Combine like terms: 14x + -14x = 0

-36 + -2x = -28 + 0

-36 + -2x = -28

Add '36' to each side of the equation.

-36 + 36 + -2x = -28 + 36

Combine like terms: -36 + 36 = 0

0 + -2x = -28 + 36

-2x = -28 + 36

Combine like terms: -28 + 36 = 8

-2x = 8

Divide each side by '-2'.

x = -4

Simplifying

x = -4
