The pair (-1, 1) is a solution to the equation 2y - 3x = 5. Find another (x, y) pair that is a

solution to the equation.

Answer:

The first one

Step-by-step explanation:

Parentheses are used to enclose incidental or extra information, such as a passing comment, a minor example or addition, or a brief explanation

Step-by-step explanation:

Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

2 −  − 12 = 0

= 1

= -1

= − 12

= −( −1) ± √ ( −1)2 − 4⋅1 ( −12)

                       2.1

Lets do

[tex]\\ \tt\longmapsto 2x^2+3x+5=0[/tex]

a=2

b=3

c=5

[tex]\\ \tt\longmapsto x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]\\ \tt\longmapsto x=\dfrac{-3\pm \sqrt{3^2-4(2)(5)}}{2(2)}[/tex]

[tex]\\ \tt\longmapsto x=\dfrac{-3\pm \sqrt{9-40}}{4}[/tex]

[tex]\\ \tt\longmapsto x=\dfrac{-3\pm\sqrt{-31}}{4}[/tex]

[tex]\\ \tt\longmapsto x=\dfrac{-3\pm \sqrt{31}i}{4}[/tex]

[tex]\\ \tt\longmapsto x=\dfrac{-3}{4}\pm\dfrac{\sqrt{31}}{4}i[/tex]

its -2

because the object increased in size but nothing else changed the slope stays the same the slope is the same as the original shape

Step-by-step explanation:

Answer:

m∠N = 72°

mNQ = 94°

Step-by-step explanation:

An inscribed angle is equal to half the measure of its intercepted arc

∠N is an inscribed angle and arc MP is it's intercepted arc

Thus, ∠N = 1/2 arc MP

if arc MP = 144

Then ∠N = 144/2

144/2 = 72

Hence, ∠N = 72°

For ∠P and arc NQ we are given the measure of the inscribed angle and need to find the measure of the intercepted arc.

If the measure of an inscribed angle equals half the measure of its intercepted arc, then the measure of the intercepted arc equals twice the measure of the inscribed angle.

Thus, arc mNQ = 2(∠P)

If ∠P = 47, then mNQ = 2(47)

2 * 47 = 94

Hence, mNQ = 94

Answer:

Volume of a cuboid = 42 cm³

Step-by-step explanation:

Volume of a cuboid = side A × side B × side C

Side A = 2 cm

Side B = 3 cm

Side C = 7 cm

Volume of a cuboid = side A × side B × side C

= 2 cm × 3 cm × 7 cm

= 42 cm³

Volume of a cuboid = 42 cm³

Answer:

86 would be the answer

Step-by-step explanation:

you add all the numbers then subtract by the number of number

Answer: 86 minutes

Step-by-step explanation:

To find the mean of something, you always add up the values and then divide by the amount.

So, in total there are 430 minutes because (170+150+45+30+35=430)

There are five different towns.

430/5=86

Answer:

$5,000,0000= total sales

Step-by-step explanation:

Giving the following information:

Commission rate= 4%

First, we need to calculate the total commission earned:

Commission= 350,000 - 125,000 - 25,000

Commission= $200,000

Now, using the following formulas, we can determine the total sales:

Commission= total sales*commission rate

200,000= total sales*0.04

200,000/0.04= total sales

$5,000,0000= total sales

Answer:

0

Step-by-step explanation:

Its prob 0 just because it does not show one, meaning that there is an invisible 0 in the y-intercept spot

Answer:

D

Step-by-step explanation:

Base area = (leg1 x leg2)/2 = (12 x 9)/2 = 54 in^2

V = (base area x height) = (54 x 12) = 648 in^3

Answer:

The angle the wire now subtends at the center of the new circle is approximately 145.7°

Step-by-step explanation:

The radius of the arc formed by the piece of wire = 15 cm

The angle subtended at the center of the circle by the arc, θ = 68°

The radius of the circle to which the piece of wire is reshaped to = 7 cm

Let 'L' represent the length of the wire

By proportionality, we have;

L = (θ/360) × 2 × π × r

L = (68/360) × 2 × π × 15 cm = π × 17/3 = (17/3)·π cm

Similarly, when the wire is reshaped to form an arc of the circle with a radius of 7 cm, we have;

L = (θ₂/360) × 2 × π × r₂

∴ θ₂ = L × 360/(2 × π × r₂)

Where;

θ₂ = The angle the wire now subtends at the center of the new circle with radius r₂ = 7 cm

π = 22/7

Which gives;

θ₂ = (17/3 cm) × (22/7) × 360/(2 × (22/7) × 7 cm) ≈ 145.7°.

Answer:

C?

Step-by-step explanation:

A) Jared makes x of a goodie bag per hour. How many

can he make in y of an hour?

B) Jared makes x of a goodie bag per hour. How many

can he make in y of an hour?

C) Jared has x of an hour left to finish making goodie  bags. It takes him y of an hour to make each goodie  bag. How many goodie bags can he make?

D) id k

Quotient is the answer to a division problem, so we need to find a problem that needs to divide x and y to find the answer. It isn't A or B, since they are asking for y, not the quotient. I have no idea what D is. C makes sense, so C might be the answer.

It tells us how much time he has(x), and how long it takes him to make 1 bag(y), and we need to find the answer, which is the quotient.

So C is the answer.

Answer:

y = 2

Step-by-step explanation:

The midline is the line that the graph is symmetrical about.

It is positioned midway between the maximum and minimum of the graph

Maximum = 3

Minimum = 1

Then equation of midline is

y =  = [tex]\frac{3+1}{2}[/tex] = [tex]\frac{4}{2}[/tex] = 2

That is y = 2
