which shape has right angles AND sides that are the same?

Formula used to calculate the y-intercept when coordinates of two points are given is as follow: y = mx + c where 'm' represents the slope and 'c' represents the y-intercept.

As given in the question,

Let us consider points of two coordinates be equal to

( x₁ , y₁ ) =  ( 2, 3 )

( x₂ , y₂ ) = ( 4, 7 )

Equation of the line is equal to :

( y - y₁ ) / ( x - x₁ )  = ( y₂ - y₁ ) / ( x₂ - x₁ )

⇒ ( y - 3 ) / ( x - 2 ) = ( 7 - 3 ) / ( 4 - 2 )

⇒ ( y - 3 ) / ( x - 2 ) = 2

⇒ y - 3 = 2x - 4

⇒ y = 2x - 1

Same as y = mx + c

Here c = -1

Here y-intercept is equal to -1 by substituting x = 0 we can get                 y - intercept.

Therefore, the value of y-intercept can be calculated with the coordinates of the given points using formula given by :

y = mx + c where 'c' represent y-intercept.

The given question is incomplete, I answer the question in general according to my knowledge:

If you're given coordinates of 2 points, how do you find the y-intercept?

Answer:

Step-by-step explanation:

using the rise over run method:

1 up and three to the right

the slope is 1/3
m = 1/3

The value of y after solving the given equation is -8.

We can calculate the value of y through the following method,

We have been provided with an exponential equation [tex]8^{y} = 16^{y+2}[/tex]

As we know, an exponential equation is an equation whose exponent or part of the exponent is a variable.

For solving an exponential equation, we need to use logarithms and their properties.

We can write [tex]8^{y}[/tex] also as [tex]2^{3y}[/tex] since we know that 2³ = 8

Similarly, we can write [tex]16^{y+2}[/tex] also as [tex]2^{4(y+2)}[/tex] since we know that [tex]2^{4}[/tex] = 16

Therefore we get the new equation as,

[tex]2^{3y}[/tex] = [tex]2^{4(y+2)}[/tex]

Now we will add log with base 10 on both the sides

Therefore the equation will become,

log₁₀ [tex]2^{3y}[/tex] = log₁₀ [tex]2^{4(y+2)}[/tex]

Since, according to the property of logarithm,

log₁₀ aᵇ = b log₁₀ a

Therefore,

3y log₁₀ 2 = 4(y + 2) log₁₀ 2

We can cancel out log₁₀ 2 on both sides

We get the equation as,

3y = 4(y + 2)

3y = 4y + 8

y = -8

Althea volunteers 10.25 hours a week.

Given that Althea volunteers in the school library for 2 1/4 hours on Mondays, Wednesdays, and Fridays.

She volunteers 2 1/4 hours a day.

First we convert the improper fraction 2 1/4 to a proper fraction.

2 1/4 = 9/4

So by unitary method for three days the number of hours she volunteer:

3 × 9/4 = 27/4

Also, she volunteers for 1 3/4 hours on Tuesday and Thursday.

She volunteers 1 3/4 hours a day.

First we convert the improper fraction 1 3/4 to a proper fraction.

1 3/4 = 7/4

So by unitary method for two days the number of hours she volunteer:

2 × 7/4 = 14/4

So, the total number of hours Althea volunteers for a week,

27/4 + 14/4

= 41/4

The equation of equilibrium states that the sum of the forces in the x-direction must be zero.

Equation of equilibrium:

F_x = 0 = mgsinθ - mgsinϕ

mgsinθ = mgsinϕ

sinθ = sinϕ

θ = ϕ

The equation of equilibrium states that the sum of the forces in the x-direction must be zero. This means that the force due to gravity in the x-direction, mgsinθ, must be equal to the force due to gravity in the x-direction, mgsinϕ. This can be rearranged to sinθ = sinϕ, which means that the angles θ and ϕ must be equal. Thus, the relationship between angles θ and ϕ is that they are equal.

At Nation Office Supply, pens are $1.69 per dozen and notepads are $4.59 per dozen.

Here, Marley purchases 9 dozen pens, and spend total $56.52.

Let number of notepads can she purchase = x

So, We can formulate;

⇒ 9 × $1.69 + $4.59x = $56.52

⇒ 15.21 + 4.59x = 56.52

⇒ 4.59x = 56.52 - 15.21

⇒ 4.59x = 41.31

Answer:

roots are real and rational

Step-by-step explanation:

given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 ) , then the discriminant is

b² - 4ac

the discriminant informs on the nature of the roots

• if b² - 4ac > 0 then roots are real and irrational

• if b² - 4ac > 0 and a perfect square, then roots are real and rational

• if b² - 4ac = 0 , then roots are real and equal

• if b² - 4ac < 0 , then the roots are not real

for 2x² + 7x + 6 = 0 , in standard form

with a= 2, b = 7 , c = 6 , then

b² - 4ac = 7² - (4 × 2 × 6) = 49 - 48 = 1

since b² - 4ac > 0 and a perfect square, then the roots are real and rational
