Answer:

Step-by-step explanation:

When a slope is undefined, it is always x = ?

The point (-5, -8) tells us that x = -5

Option A also has a point with x = -5

Help???<br> Its a two step inequality problem. I dunno what X equals too.

Verizon [17]

Answer:

$x \geq -1$

Step-by-step explanation:

$-4x + 2 \geq -6x$

Add $6x$ to both sides:

$-4x + 2 + 6x \geq -6x + 6x$

$2x + 2 \geq 0$

Subtract 2 from both sides:

$2x + 2 - 2 \geq 0 - 2$

$2x \geq -2$

Divide both side by 2:

$\frac{2x}{2} \geq \frac{-2}{2}$

$x \geq -1$

I need to know the surface area of these

anastassius [24]

Answer:

245 cm²

Step-by-step explanation:

The surface area of a cone is given by ...

SA = πr(r +s) . . . . where r is the radius, and s is the slant height

Filling in the given values, we have ...

SA = (3.14)(3 cm)(3 cm +23 cm) = (3.14)(3)(26) cm² ≈ 245 cm²

The surface area of the cone is about 245 cm².

Two pairs of statements about Jeff's housing expenditures are given below. How can both pairs of statements be true?

Irina18 [472]

Explanation:

Pair 1 is true if Jeff's monthly income is $600/20% = $3,000.

Pair 2 is true if Jeff's monthly income is $1200/10% = $12,000.

Both pairs can be true if Jeff's monthly income increased by a factor of 4 in the 20 years from 1990 to 2010.

Obviously, Jeff spent more on housing in 2010. (Fortunately for Jeff, that larger expenditure was a smaller fraction of his income.)

Two ships leave a harbor together, traveling on courses that have an angle of 135°40' between them. If they each travel 402 mile

mario62 [17]

Answer:

Therefore they are 734.106 miles apart.

Step-by-step explanation:

Given that ,

Two ships have a harbor together. The angle between two ships is 135°40'. Each of two ships travel 402 miles.

It forms a isosceles triangle whose two sides are 402 miles and one angle is 135°40'. Since it is isosceles triangle then other two angles of the triangle is equal.

Let ∠B= 135°40', and AB = 402 miles , BC = 402 miles

Then the distance between the ships = AC

We know

The sum of all angles = 180°

⇒∠A+∠B+∠C=180°

⇒∠A+135°40'+∠C=180°

⇒2∠A= 180°- 135°40' [ since ∠A=∠C]

⇒2∠A=44°60'

⇒∠A= 22°30'

Again we know that,

$\frac{AB}{sin\angle C}=\frac{BC}{sin \angle A}=\frac{AC}{sin \angle B}$

Taking last two ratio,

$\frac{BC}{sin \angle A}=\frac{AC}{sin \angle B}$

Putting the value of BC , AC ,∠A,∠B

$\frac{402}{sin 22^\circ30'}=\frac{AC}{sin 135^\circ40'}$

$\Rightarrow AC=\frac{402 \times sin135^\circ40'}{sin 22^\circ30'}$

≈734.106 miles

Therefore they are 734.106 miles apart.
