Answer:

x = -3/10

Step-by-step explanation:

Solve for x by substituting y = 3x into the other equation:

2x - 4y = 3

2x - 4(3x) = 3

Simplify and solve for x:

2x - 12x = 3

-10x = 3

x = -3/10

So, x = -3/10

Answer:

[tex]x=-\frac{3}{10}[/tex]

Step-by-step explanation:

2x - 4y = 3

y = 3x

2x - 4(y = 3x) = 3

2x - 4(3x = 3)

2x - 12x = 3

- 10x = 3

- 10x ÷ - 10 = 3 ÷ - 10

[tex]x=-\frac{3}{10}[/tex]

If I'm not mistaken the answer is 44

Answer:

x = 9

Step-by-step explanation:

Corresponding sides are in proportion, that is

[tex]\frac{x}{24}[/tex] = [tex]\frac{3}{8}[/tex] ( cross- multiply )

8x = 72 ( divide both sides by 8 )

x = 9

Answer:

Step-by-step explanation:

4 + (-7) = -3

First mark the the first number (4) in the number line. Then check the second number. Here it is (-7). As it is negative, we have to move to left hand side in the number line  - 7 jump towards left.  The final number where the jump ends will give the answer.

Answer:

Step-by-step explanation:

125=2x+17(being vertically opposite angle)

125-17=2x

108/2=x

54=x

Answer:

Slope = rise/run

Rise = 0

So zero divided by any run is 0.

B

Answer:

B

Step-by-step explanation:

slope or gradient = rise/run

rise=0 0/anything= 0

Line B has no graidient so it is considered as 0.

[tex] - \frac{2}{3} a + 6 = - 14[/tex]

[tex](3)( - \frac{2}{3} a + 6) = ( - 14)(3)[/tex]

[tex] - 2a + 18 = - 42[/tex]

[tex] - 2a + 18 - 18 = - 42 - 18[/tex]

[tex] - 2a = - 60[/tex]

[tex] - 2a \div - 2 = - 60 \div - 2[/tex]

[tex]a = 30[/tex]

Answer:

x+4 + 3x +2

x+3x+4+2

4x+6

4x+6=90

4x=90-6

4x=84

4x/4 = 84/4

x= 21

Answer:

X is a variable and can represent any number that is unknown

Answer:

B. Decreasing

Step-by-step explanation:

From the table, we can see that as variable x increases, variable y decreases relatively.

If the data points are plotted on a scatter plot, the trend line would be sloping downwards from our left to our right. This shows that the trend line is decreasing because the sloping downwards from the left to the right shows implies a decrease.

both triangles are isosceles

done!

Answer:

The answer is 3/4 because 2/4 + 1/4 = 3/4.

Answer:

x = 3

Step-by-step explanation:

8x- 5= 19

8x= 19+5

8x= 24

x= 24/ 8

x= 3

Explanation:

Vertical angles are always opposite one another, and they form after intersecting two lines. Vertical angles are always congruent (i.e. the same measure).

Answer:

the solution is the whole line y = -x + 7

Step-by-step explanation:

both equations are identical

2y = 14 - 2x

=> y = 7 - x

which is exactly the same information as y=-x+7

so, there is no single crossing point. they are exactly covering each other. what "remains" is simply the whole line.

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.

Translation is the movement of a point either up, down, right or left in the coordinate plane. If a point A(x, y) is moved a units up and b units right, then the new point is at A'(x + b, y + a).

Given that the knight is moved from (3, 2) to (5, 1), hence it is moved 2 squares right and 1 square down.

If the knight is moved from (5, 1) to (6, 3), it is moved 1 square right and 2 squares up.

Answer:

7x + 6 = - 48

Step-by-step explanation:

Given

[tex]\frac{7}{8}[/tex] x + [tex]\frac{3}{4}[/tex] = - 6

Multiply through by 8 ( the LCM of 8 and 4 ) to clear the fractions

7x + 6 = - 48 ← same equation without fractions

Answer:

3 hours 39 minutes

Step-by-step explanation:

6 to 10 = 4 hours

35 to 14 = -21

4 x 60 = 240

240 - 21 = 219

220 to hours and minutes = 3 hours and 39 minutes

I was taught this before and my teacher always said if its a open circle then its > or < if its a closed circle then it should have the line under it, and the line is going down so it would be Less than sign

Answer:

Step-by-step explanation:

f(x)= x²

the shape of f (x ) and g( x ) is same.

and those graphs lower point is ( 0 , 0 )

therefore,

will, g(x) = kx²    (k ∈ real numbers)

the g(x) graph goin through the point ( 1 , 4 )

therefore,

4 = k × 1²

k = 4

∴ g(x) = 4x²
