**Answer:**

**Step-by-step explanation:**

First, let’s flip the first term.

2^-x = 8^2-x

we can take ^3 out of the 8 to simplify

2^-x = 2^3(2-x)

-x = 3(2-x)

Now we solve for x.

x = 6

Solve for the variable 2y<14 A) y<12 B) y>-7 C) y>7 D) y<7

**Answer:**

D) y < 7

**Step-by-step explanation:**

So we have 2y < 14:

To solve, we will simply divide by 2 on both sides in order to isolate the y value. Now we have **y < ****7**.

∠A and \angle B∠B are vertical angles. If m\angle A=(2x-10)^{\circ}∠A=(2x−10) ∘ and m\angle B=(x+8)^{\circ}∠B=(x+8) ∘ , then find the measure of \angle A∠A.

**Answer:**

m∠B=52

∘

Step-by-step explanation:

Two or more angles are said to be complementary if they sum up to 90 degrees.

Given that angles A and B are complementary, then:

\begin{gathered}\angle A+\angle B=90^\circ\\m\angle A=(2x+18)^{\circ}\\m\angle B=(6x-8)^{\circ}\\$Therefore:\\(2x+18)^{\circ}+(6x-8)^{\circ}=90^\circ\\2x+6x+18-8=90^\circ\\8x+10^\circ=90^\circ\\8x=90^\circ-10^\circ\\8x=80^\circ\\$Divide both sides by 8\\x=10^\circ\\$Therefore:\\m\angle B=(6x-8)^{\circ}\\m\angle B=(6(10)-8)^{\circ}\\=60-8\\m\angle B=52^{\circ}\end{gathered}

the three altitudes of a triangle intersect at the:

Explanation:

An altitude of a triangle extends from one vertex to the opposite side, where this altitude is perpendicular to the opposite side. The term "altitude" is often interchanged with "height". Think of a tall mountain that has a lot of altitude, so it's got a lot of height.

Any triangle has 3 different altitudes (one per corner). For any triangle, those three altitudes always intersect at exactly one point: the **orthocenter**. This is one of the many centers of a triangle. Other centers are the centroid, incenter, and circumcenter.

FURNITURE A modern table is constructed with four legs made

of concrete cubes with cube-shaped notches.

a. Define one or more variables and write an expression that

represents the volume of one table leg.

b. Marisol determined that she will use 12,636 cubic inches of

concrete to construct the four table legs. If the sides of the

notches are 40% of the sides of the legs, how long are the sides of the legs?

The **volume **of a shape is the amount of space in it.

(a) The volume of one table leg

Represent the **side length **of the **leg **with l, and the **side length **of the **notch **with n.

So, the **expression **that represents the **volume **of **one table leg **is:

[tex]V = l^3 + n^3[/tex]

(b) The length of the sides

From the question, we have:

[tex]n = 40\% \times l[/tex]

Express 40% as decimal

[tex]n = 0.40 \times l[/tex]

[tex]n = 0.4l[/tex]

Substitute 0.4l for n in [tex]V = l^3 + n^3[/tex]

[tex]V =l^3 + (0.4l)^3[/tex]

[tex]V =l^3 + 0.064l^3[/tex]

[tex]V =1.064l^3[/tex]

The **volume **of the **4 legs **is given as: 12636

So, the **volume **of **one leg **would be 12636/4

So, we have:

[tex]1.064l^3 = \frac{12636}{4}[/tex]

[tex]1.064l^3 = 3159[/tex]

Divide both sides by 1.064

[tex]l^3 = 2968.985[/tex]

Take cube roots of both sides

[tex]l = 14.37[/tex]

Hence, the **sides **of the **legs **is 14.37 inches long

**Step-by-step explanation:**

Which equation, when graphed, has x-intercepts at (2, 0) and (4, 0) and a y-intercept of (0, â€"16)? f(x) = â€"(x â€" 2)(x â€" 4) f(x) = â€"(x 2)(x 4) f(x) = â€"2(x â€" 2)(x â€" 4) f(x) = â€"2(x 2)(x 4).

To find the **equation**, for the **x-intercepts** at (2, 0) and (4, 0) and a **y-intercept** of (0, –16) we have to find the nature of the** curve**.

The **correct option **is f**(x) = –2(x – 2)(x – 4)**.

Given:

The x-intercepts at (2, 0) and (4, 0).

The y-intercept of (0, –16).

The nature of the **graph **is** quadratic curve**. Write the **general equation **for x-intercept.

[tex]y=a(x-2)(x-4)[/tex]

Where is [tex]a[/tex] **number**

Substitute 0 for [tex]x[/tex].

[tex]y=a(0-2)(-4)\\y=8a[/tex]

We have y-intercept of (0, –16).

[tex]-16=8a\\a=-2[/tex]

The **equation **would be,

[tex]f(x) = -2(x - 2)(x - 4).[/tex]

Thus, the correct option is f(x) = –2(x – 2)(x – 4).

In the equation, y=3x+2, is the point (2,8) a solution the equation?

1: Yes, the point is solution

2: No, the point is not a solution

**Answer:**

Given: The equation of the line y = 3x+2

The condition for a point to be on a line is to satisfy its equation

(i) Let us consider (1/3, 3), substitute x = 1/3 and y = 3 in given equation

3 = 3(1/3) + 2

= 1 + 2

= 3

Hence, (1/3, 3) lies on the line

(ii) Let us consider (2, 8) and substitute x = 2 and y = 8 in given equation

8 = 3(2) + 2

= 6 + 2

= 8

Hence, (2, 8) lies on the line

(iii) Let us consider (0, 2) and substitute x = 0 and y = 2 in given equation

2 = 3(0) + 2 = 2

Hence, (0, 2) lies on the line(iv) Let us consider (7, 19) and substitute x = 7 and y = 19 in given equation

19 = 3(7) + 2

= 21+ 2

= 23 ≠ 19

hence, (7,19) doesn’t lie on the line• Therefore ,Yes the point is a solution .**Step-by-step explanation:**

Yes, the point is a solution

The point (2,8) means that whenever x=2, the y=8.

If you substitute x=2, then y=3(2)+2=8!

The point (2,8) means that whenever x=2, the y=8.
