Answer:

2. (1) [tex]30[/tex]

3. (1) [tex]y=\frac{1}{4}x[/tex]

4. a) [tex]y=x+6[/tex]   b) [tex]42[/tex]

Step-by-step explanation:

In a proportional relationship, y=2 when x=8, the following lines will show this relationship,

1.   y = 1/4x

2.  y = x - 6

4.  y =  1/2x - 2

The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.

Given that,

The point,

x = 8 and  y = 2

We have to check all the given options,

1.   y = 1/4x

     y  = 1/4 × 8

     y  =  2

2.  y   = x - 6

         = 8 - 6

    y   =  2

3.  y   = 4x

         = 4 × 8

    y   = 32

4.  y   = 1/2x - 2

         = 1/2 × 8 - 2

         =  2

Hence, Option 1, 2, & 4 satisfies the given condition

Answer:

True

Step-by-step explanation:

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

Answer:

x= 20, y=95

Step-by-step explanation:

If you see the x angle, it makes 90 degree, and the straight line divides that angle into two. So by that;

x+25=45

x=20

Now if you add up all the angles on the straight line, it makes 180 degree,

by that,

x+25+y+40=180 (straight lines' angle=180 degree)

we now know that x=20, so now by adding that value, we get

20+25+y+40=180

y=180-40-25-20

y=180-85

y=95.

Answer:

  11.2

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relevant relation:

  Cos = Adjacent/Hypotenuse

  cos(37°) = x/14

  x = 14·cos(37°) ≈ 11.1809

The value of x is about 11.2.

Answer:

To eliminate a variable in the system, we will have to subtract both expressions from each other

Step-by-step explanation:

Given the equations

5x+8y=-1

5x -8y=-7

To eliminate a variable in the system, we will have to subtract both expressions from each other

5x - 5x +8y-(-8y) = 1-(-7)

0 + 16y = 8

16y = 8

You can see that the variable x has been eliminated by simply subtracting both equations

y = 8/16

y = 1/2

Answer:

here!

Step-by-step explanation:

so graphing lines are pretty hard but this one is fairly simple. here the slope formula format is y=mx+b

m being the slope

and b being the y-intercept

so as you can see your equation has no slope meaning your line is just going to be straight

and then if you take a look to find the only other thing your equation has in it is a 6 as the y-intercept meaning in order to graph this find where 6 is on the y-axis (the vertical line on the side) and draw a line going horizontal and put a dot or a point on (0,6) to mark that you have found the y-intercept and that this is the only known point on your line graph so far with the information given. i hope this makes sense, and have a great day!

The equation that is not equivalent to 2x + 14 = 4x - 6 is c) 2x - 4x = -20

To determine which equation is not equivalent, we need to simplify each option and see if it yields the same solution as the original equation.

Option c) simplifies to -2x = -20, which is different from the original equation. In the original equation, we have 2x + 14 = 4x - 6.

Therefore, the equation 2x - 4x = -20 is not equivalent to 2x + 14 = 4x - 6.

Answer:

ASA

Step-by-step explanation:

We can see that the triangle has at least one similar side and one similar angle. We can also see that the triangles meet at a point, so they must have the same angle at that point where they connect. So that leads us to our answer being ASA since they have two similar angles and one similar side. This is the answer that I think is correct just by looking at the image. I haven't take this class since last year, so this is simply from memory. Correct me if I am wrong!

Solve for L

L=A/W

Substitute

L=(32x^2+12)/4x

L=(8x^2+3)/x

Answer:

1250 students go to Excellent Elementary.

Step-by-step explanation:

Given that 4% of the students at Excellent Elementary are vegetarians, you can subtract 4% from 100% to find the percentage of students that are non-vegetarians:

100%-4%=96%

Now, since you know that 96% of the students are non-vegetarians and that they are 1200, you can use a rule of three to find the amount that represents 100% which would be the total amount of students that go to Excellent Elementary:

96%    →    1200

100%   →       x

x=(100*1200)/96

x=1250

According to this, the answer is that 1250 students go to Excellent Elementary.

Answer:

The cost of the house after one year = 84,750 rupees

Step-by-step explanation:

Explanation:-

Given that the cost of house = 13% in one year

Given that the house original price = 75000

We have to find that the house cost after one year

Solution:-

The cost of a house increase 13% per year

                        = 75000 X 0.13

                       = 9750

The total cost = 75000+9750

                      = 84,750 rupees

Final answer:-

The cost of the house after one year = 84,750 rupees
