Answer 1

Answer: The attachment is a bit difficult to read, and long.  I'll make some suggestions and add some detail to a few of the problems, but would ask that these suggestions be applied to other problems to find the answers.

Step-by-step explanation:

9.   Coinciding lines line on top of each other.  I.e., they are the same equation.  If we take A, for example, we can reduce the second expression by dividing by 2:  (2x+4y=6)/2 = (x + 2y = 3).  This matches the first expression (x + 2y = 3).  !   Whoa, that went fast.

10.   (x+8)(x-8) = x² +8x -8x - 64 = x² - 64

11.  I don't have the time to explain how one can factor, but practice is important.  And I don't know if this is completely factored, but it matches one of the options.  Try (n-2)(n²+2n + 4)  [n³ +2n² +4n - 2n² -4n -8 = n³ - 8.  It works.

12.  The denominators are the same, so add the numerators and keep the denominator.  (7x+4y)/x²y

13.  The slope is the "Rise" over the "Run."  (3,4), (8,-1)  Rise = (-1 - 4) = -5.  Run = (8-3) = 5  Slope = -(5/5) = -1

14.  A line with a positive slope will move upwards as x increases.  We can eliminate options C and D immediately.  That leaves A and B.  The line we are looking for is y = 5x + b.  We are not given b, the y-intercept, so determine the slopes of both lines:  I get 4 for A and 5 for B.  To confirm B is correct, we could calculate b for y=5x+b by using given point, (2,3).  3 = 5*2 + b, b = -7.  We can't see this point (0,-7) on the graph, but it appears correct.  B is the best answer.

15.  The line will have the form of y=mx+b.  Calculate m, the slope, from the two points (3,1) and (4,7).  Rise = 6, Run = 1  Slope = 6.  y=6x+b.  Find b by using either of the given poins and solving for b.  I'll choose (3,1).  y=6x+b;  1 = 18 + b; b = -17.  The equation is y=6x-17.  Rearrange option A (y =6x - 17).

16.  The second value in each factor must, when multiplied together, equal the final term of the original expression, -9y².  I see only one option for which that is true, C.  Multiply the two factors in C to be certain, and you'll find they result in the correct expression.

Step-by-step explanation:

a)

105/3 = 35

35/5 = 7

7/7 = 1

429/3 = 143

143/11 = 13

13/13 = 1

Not co-prime

For the other parts of the problem, do the same I did above. Find the prime factorizations of both numbers, and see if they have any prime factors in common.

3-1/8a=1/4

Pleasseeee help

Answers

3 - 1/8a = 1/4

The goal is to isolate "a" and its coefficient to make the simplification process easier.

Start by subtracting 3 from both sides:

3 - 3 - 1/8a = 1/4 -3

-1/8a = 1/4 - 3

Next, multiply 3 by 4/4 to convert it into a fraction:

-1/8a = 1/4 - [3 • (4/4)]

-1/8a = 1/4 - 12/4

-1/8a = - 11/4

Multiply both sides by -8:

(-8) -1/8a = - 11/4 (-8)

a = 88/4 = 22

Therefore, a = 22.
a = 22 the correct answer

Answer: (-1, 14) and (-8, 75)

Plug in the numbers and see if it’s true. We know that the x intercept is in the front and the y intercept is in the back.

(x,y)

So with the first choice the x = -1; y = 14

14 > -10(-1) -1

14 > 9

So this is an answer

Do the same with every choice and see what works

You pull horizontally on a 50-kg crate with a force of 450 n and the friction force on the crate is 250 n. the acceleration of the crate is​

Answers

Hello AljakeVillena!

[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]

You pull horizontally on a 50-kg crate with a force of 450 n and the friction force on the crate is 250 n. the acceleration of the crate is ?

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

Given,

mass of crate = 50 kgForce you pull it with = 450 NFrictional force = 250 NAcceleration = ?

__________________

Let's first find the total force/net force acting on the crate. The total force will be :-

450 N - 250 N = 200 N.

We subtracted the forces because both the forces act on opposite directions.

__________________

Now, let's find the acceleration of the crate. To find the acceleration we must divide the net force by the mass. So,..

Acceleration = Force/massa = F/ma = 200/50a = 4 m/s²

__________________

So, the acceleration of the crate is 4 m/s².

Force is mass times acceleration for linear motion. The acceleration of the crate in considered situation is  4 N/kg

How to calculate the acceleration from mass and force given?

If net force is applied on an object of mass "m" in linear direction, with magnitude F, then, acceleration of that object is:

[tex]a = \dfrac{\rm F}{\rm m} \: \rm[/tex]

(assuming one dimensional motion, force is also in that dimension).

Here, it is given that crate's mass m = 50kg

Force pulling the crate = 450 N (positive since it is in direction of motion (horizontal)

Force resisting the crate = -250 N (negative since it is opposite to the direction of motion).

Net force on crate = 450 N + (-250 N ) = 200N (positive, thus, in the direction of motion).

Acceleration of the crate = 200/50 = 4 N/kg

Thus,  the acceleration of the crate in considered situation is  4 N/kg
