Answer:

9,427) y=5

is correct answer

Answer:

a = 16

Step-by-step explanation:

[tex]y + 4 = \dfrac{3}{4}(x-8)\\\\y + 4 = \dfrac{3}{4}x- \dfrac{3}{4}*8\\\\y +4 = \dfrac{3}{4}x-3*2\\\\y+4+6= \dfrac{3}{4}x \\\\y+10= \dfrac{3}{4}x[/tex]

Now plugin x = a and y =2 in the above equation,

[tex]2+10= \dfrac{3}{4}*a\\\\12= \dfrac{3}{4}a\\\\12* \dfrac{4}{3}=a\\\\a=4*4\\\\a=16[/tex]

Answer:

5 <= x <= 8

Step-by-step explanation:

x/5 (*5) >= 1 (*5)

x >= 5

x-1 (+1) <= 7 (+1)

x <=8

If we compare both sides of the equation we get,

D. a = 4, b = 6 and c = 5

Answer:

Associative property of multiplication

Step-by-step explanation:

The word "associative" comes from "associate" or "group"; the Associative Property is the rule that refers to grouping. For addition, the rule is "a + (b + c) = (a + b) + c"; in numbers, this means 2 + (3 + 4) = (2 + 3) + 4. For multiplication, the rule is "a(bc) = (ab)c"; in numbers, this means 2(3×4) = (2×3)4.

Answer:

5

Step-by-step explanation:

If you want to divide ten blocks into two groups just imagine you split all of the blocks evenly, so you have ten and to have an equal amount of blocks on two sides you will put five on each side, then your answer is five because you are able now to equally divide them into two groups.

Happy Halloween if you celebrate it!

Answer:

Step-by-step explanation:

This is basically the same thing as the last question.

The domain goes from - 8 to 5. The 5 has an open circle for it's endpoint < does not include the end point

the range is a little tricky. It goes from - 6  to 9. The -6 is has a circle (because it is not included in the answer). I'm not sure how you show that on a graph.

I think the best answer is this: if either the domain or range is separated by < then you must change the one that uses ≤ into < so the endpoints of the domain are in agreement. You cannot have the domain using < when the range uses ≤. They both must be the same. I think the best choice is<

Answer:

  see attached

Step-by-step explanation:

The function can have virtually any shape between the ends of the domain and range. The function can have any value in the range at x = -8, and can have any value in the domain at y = 9.

The attachment shows two different functions having the required characteristics.

Answer:

The length is 83 and the width is 57

Step-by-step explanation:

The width is 26 meters less than the length, so we'll represent the width with: L-26. Since there are 2 widths to account for, we'll multiply this by 2.

Equation looks like this so far: 2(L-26)

Then, add the 2 lengths and set the expression equal to 280.

Equation: 2(L-26)+2L=280

Distribute the 2 in the first term, making the equation look like:

2L-52+2L=280

Add the 52 to both sides of the equation

4L=332

Divide by 4 on both sides

L=332/4=83

L=83

Width is 26 meters less, so 83-26=57

W=57

Answer:

A train leaves the station at 9:00 pm traveling east at 36 miles per hour. A second train leaves the station at 10:00 pm traveling west at 42 miles per hour. At what time will both trains have traveled the same distance?

------

Let t equal the time that passed right after 10 PM.

42t = 36 (t + 1)  

42t = 36t +36  

6t = 36  

t = 6 hours

Answer: 4 AM ✅

Step-by-step explanation:

The car traveled 200 m distance with a speed of 50 m / hr in 4 hr.

Given that,
To determine the total distance in meters of a car that travels due west at 50 m/hr west between 12:00 and 4:00 pm.

Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

Distance is defined as the object traveling at a particular speed in time from one point to another.

Here, the car travels due west at 50 m/hr west between 12:00 and 4:00 pm
Time = 12:00 - 4:00 = 4 hours
Speed = 50 m / hr
Distance = 50 * 4
             = 200 m

Thus, the car traveled 200 m distance with a speed of 50 m / hr in 4 hr.

Answer:

[tex]-\frac{4}{7} -\frac{8}{7} i\sqrt{5}[/tex]

Step-by-step explanation:

To rationalize the denominator, we would have to multiply by the complex conjugate of 6 + 2i√5 which is 6 - 2i√5:

[tex]\frac{8-8i\sqrt{5} }{6+2i\sqrt{5} } *\frac{6-2i\sqrt{5} }{6-2i\sqrt{5} }[/tex]

The denominator resembles the difference of squares:

6^2 - (2i√5)^2

36 + 20

56

Next we would need to multiply the numerator, but before, notice we can factor out 8 from 8 - 8i√5:

[tex]\frac{8(1-i\sqrt{5})(6-2i\sqrt{5}) }{56}[/tex]

We can cancel that 8 with that 56 in the denominator:

[tex]\frac{6-2i\sqrt{5}-6i\sqrt{5}-10}{7}[/tex]

This simplifies to:

[tex]\frac{-4-8i\sqrt{5} }{7}[/tex]

which is the same as:

[tex]-\frac{4}{7} -\frac{8}{7} i\sqrt{5}[/tex]

  D  y²/5 -x²/4 = 1

Step-by-step explanation:

The y-intercept is about 2.2, or √5. This point (0, √5) only satisfies the equation of the last choice:

Additional comment

The second attachment tells you the foci are located at (0, ±(a²+b²)), where a² and b² are the denominators in the above equation. That is the foci are ...

  (0, ±√(4+5)) = (0, ±3) . . . . as shown in the graph

This confirms the equation denominators are rightly 5 and 4, with 5 being the denominator of y².

The second attachment has the equation for a hyperbola that opens along the x-axis. Interchange the variables x and y to get the hyperbola shown in this problem statement.
