Translate the sentence into an equation.
Luba_88 [7]

Answer:

The expression of the given statement is 8 y - 2  = 6.

Step-by-step explanation:

Here, let the unknown number = y

Now, product of y and 8 =  8 times  y   =   8 y

Also, two less than the product    =  Product - 2

So, two less than the product  of 8 and y =  8 y - 2

Now, this above expression is equivalent to 6.

⇒8 y - 2  = 6

Hence the expression of the given statement is 8 y - 2  = 6.

Khan Academy Question
Mama L [17]

Answer:

84

Step-by-step explanation:

Since we are given line OP perpendicular to line DR, then angles PDR and ODR are right angles.

Angles PDA and ADR are complementary.

Angles ODU and UDR are complementary.

Angles ADR and UDR are given as congruent.

We can conclude that angles PDA and ODU are congruent.

By AA Similarity, triangles APD and UMD are similar.

DP/DM = PA/MU

3.75/10 = 4.5/MU

3.75MU = 10 × 4.5

MU = 12 (altitude of triangle DUO)

OD = OM + MD =  4 + 10 = 14 (base of triangle DUO)

area = base × height / 2

area = 14 × 12 / 2

area = 84

babunello [35]

To find the slope, you use the slope formula (m):

m=\frac{y_2-y_1}{x_2-x_1}    and plug in the two points

(-3, 4) = (x₁, y₁)

(2, -1) = (x₂, y₂)

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{-1-4}{2-(-3)}       [two negatives cancel each other out and become positive]

m=\frac{-1-4}{2+3}

m=\frac{-5}{5}

m = -1        The slope is -1

A parabola is represented by the equation y2 = 5x. which equation represents the directrix?
ivann1987 [24]

The value of the directrix is -5/4.

According to the statement

we have given that the equation of parabola is y2 = 5x. And we have to find that the which equation represents the directrix.

We know that the general equation of parabola is

(y - k)2 = 4a(x - h)  -(1)

and given parabola equation is

y2 = 5x.  -(2)

After comparing the both equations we get k=0 and h=0

And the formula to find the directrix is

x = h - a

Substitute the values of h and a in it then

x = 0-5/4

x = -5/4.

Here the directrix is -5/4.

So, The value of the directrix is -5/4.
