Which ordered pair is a solution of y=x-4?
(-1,-5)
(0, -3)
(2, 6)
(3, 1)

an absolute value equation is always a twin equation in disguise, so

[tex]6|x-7|=48\implies |x-7|=\cfrac{48}{6}\implies |x-7|=8\implies \pm(x-7)=8 \\\\[-0.35em] ~\dotfill\\\\ +(x-7)=8\implies \boxed{x=15} \\\\[-0.35em] ~\dotfill\\\\ -(x-7)=8\implies x-7=-8\implies \boxed{x=-1}[/tex]

Answer:

1) Center = A → centermost point of a circle.

2) Radius = AB, AC → distance from centre to any point on the surface of the circle.

3) Diameter = BC → longest chord; distance from 1 point of the circle to another which passes through the centre of the circle.

4) Chord = IH → distance from 1 point on the circle to another.

5) Tangent = GF → external line which passes through only 1 point of the circle.

6) Secant = DE → external line which passes through 2 points on the circle.

The cost per person for 25 people is 15.20

An inverse variation is represented as:

k = xy

Where:

So, we have:

40 * 9.50 = 25 * y

Divide both sides by 25

y = 15.20

Hence, the cost per person for 25 people is 15.20

Answer: 900 degrees

Step-by-step explanation:

The formula for the sum of the interior angles is (n-2)*180 where n is the number of sides.

In this case, there are 7 sides so the sum of the interior angles would be

(7-2)*180

= 5*180

= 900 degrees

Answer:

$5.37

Step-by-step explanation:

Given the information, it will be easier to start with the pennies, dimes, and nickels and end with the quarters.

50 * 0.14 = P

50 * 0.14 = 7 pennies

50 * 0.38 = D

50 * 0.38 = 19 dimes

6 + P = N

6 + 7 = 13 nickels

50 - (P + D + N) = Q

50 - (7 + 19 + 13) = 11 quarters

(7 * 0.01) + (19 * 0.1) + (13 * 0.05) + (11 * 0.25) = 5.37

Answer:

A gum and a cracker

Step-by-step explanation:

She receive 3 of the same type of coin as change => the leftover change should be divisible by 3

If she buy a gum and a cracker, she would be leftover with 100 - (50+35) = 15 cents.

And that is divisible by 3, so we can conclude she bought a gum and a cracker.

Answer:

[tex](6, 9)[/tex]

Step-by-step explanation:

The point of intersection is also the solution to this system of equations.

We can solve this system using substitution:

[tex]x+y=15\\x+2x-3=15\\3x-3=15\\[/tex]

Add 3 to both sides:

[tex]3x=18[/tex]

Divide both sides by 3

[tex]x=6[/tex]

Then, substitute 6 for x to solve for y:

[tex]y=2x-3=2(6)-3=12-3=9[/tex]

Therefore the point of intersection is:

[tex](x, y)=(6, 9)[/tex]

Answer:

The profit percentage is 25%.

Step-by-step explanation:

Solution :

Selling price = Rs. 600

Profit = 1/5 of the selling price

Profit percentage = ??

Profit = 1/5 of the selling price

600 × 1/5 = 120

Profit = Rs. 120

Cost price = Selling Price - Profit

= 600 - 120

= 480

Profit pecentage -

P% = (SP - CP)/CP × 100

= (600 - 480)/480 × 100

= 120/480 × 100

= 1/4 × 100

= 25%

Hence, the profit percentage is 25%.

In order to calculate the tangential speed of the orbiting object   Hannah need the distance of the orbiting object to Earth.

The tangential speed of an object is the linear component of the speed, which is moving in a circular path.

In terms of  the gravitation constant, the tangential speed can be given as,

[tex]v=\sqrt{\dfrac{Gm}{r}}[/tex]

Here, {G} is the gravitation constant, (m) is the mass and (r) is the radius.

Hannah has information about an object in circular orbit around Earth.

The mass of the earth is.

[tex]m_E=6. 0 \times10^{24} kg[/tex]

The value of gravitational constant is,

[tex]G=6. 67\times 10{-11}\rm Nm^2/kg^2[/tex]

The radius of the earth is,

[tex]r_E=6. 0 \times 10^6 \rm m[/tex]

Here, only the distance of the orbiting object to Earth is need to find the tangential speed of the object.

Hence, in order to calculate the tangential speed of the orbiting object   Hannah need the distance of the orbiting object to Earth.

Polynomial Roots Calculator is a set of methods aimed at finding values of k for which F(k)=0

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers k which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 4 and the Trailing Constant is 1.

The factor(s) are:

Set the denominator as the highest number possible, 100.

[tex]\frac{400}{100}[/tex]

That is an improper fraction. Convert that to a mixed number.

[tex]\frac{400}{100} = 4[/tex]

Do the equation, 4 to the power of 2.
