Answer:

1). Yes

2). Yes

3). No

Step-by-step explanation:

1). y = 3

We can rewrite this equation in the slope-intercept form as,

y = 0.x + 3

Here, slope = 0

y-intercept = 3

Therefore, it's a linear relation.

YES.

2). 2x - 5y = 10

5y = 2x - 10

y = $\frac{2}{5}x-2$

Therefor, it's a linear function.

YES

3). y = x(x + 3)

y =x² + 3x

Since, this equation is a quadratic equation,

It's not a linear function.

Two steamers leave a port on a river at the same time, traveling in opposite directions. Each is traveling 22 mph. How long will

vivado [14]

It took both 2.5 hours to be 110 miles apart

Speed is the ratio of distance travelled to time taken. Speed is given by:

Speed = distance / time

Since both steamers is travelling at 22 mph. therefore they cover the same distance at the same time. For them to be 110 miles apart, they need to each have covered 55 miles in the opposite direction

22 = 55/time

time = 2.5 hours

Therefore after 2.5 hours they would have covered 55 miles each therefore being 110 miles apart.

Answer:

The "inverse operation" is just a way of saying "what do you do to isolate the variable". In this case, we isolate y, so we have to move all terms to the right side. To do that, we subtract 12 from each side to there will only be "y" on the left side.

The latest poll of 400 randomly selected residents showed that 288 of them are hoping that the old town cinema stays open on Mai

Varvara68 [4.7K]

The approximate margin of error is 4%.

Using the formula given and our information, we have:

$E=1.96\times \sqrt{\frac{\frac{288}{400}(1-\frac{288}{400})}{400}}
\\
\\=1.96\times \sqrt{\frac{0.72(1-0.72)}{400}}=1.96\times \sqrt{\frac{0.72(0.28)}{400}}
\\
\\=0.044\approx 0.04=4%$

My answer is 8, but I'm not completely sure, if I'm wrong could someone please explain how to find the length.

Verdich [7]

By knowing that S is bisected by the line shown, we will conclude that PD = 8

So here we know that PC = 8, we also can see that:

PCS is a right triangle
PDS is a right triangle.

Notice that because the blue line bisects S, the angle at "S" on both of these right triangles is the same, and because both of these are right triangles, both must have a 90° angle.

Finally, if two angles are equal, then the 3 angles must be equal between these two triangles.

And notice that both of these triangles share one side, then:

Triangles we know for sure that triangles PCS and PDS have the same angles and one equal side.

This implies that the triangles are congruent, thus, the <u>measures of the corresponding sides must be the same.</u>

<u />

Then the length of the shorter side of both triangles must be the same, in triangle PCS the short leg measures 8 units, then in triangle PDS the short leg, PD, also must measure 8 units.

So you are correct.
