Can you help me with this math problem please?

Answer:

x - y = 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

x + y = - 5 ( subtract x from both sides )

y = - x - 5 ← in slope- intercept form

with slope m = - 1

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-1}[/tex] = 1 , thus

y = x + c ← is the partial equation

To find c substitute (7, 3) into the partial equation

3 = 7 + c ⇒ c = 3 - 7 = - 4

y = x - 4 ← equation in slope- intercept form

subtract y from both sides

0 = x - y - 4 ( add 4 to both sides )

4 = x - y , that is

x - y = 4 ← equation in standard form

Answer:

1/2=0.5

Step-by-step explanation:

Answer:  4/9

Step-by-step explanation:

Let x represent the denominator. Then the fraction is: (x - 5)/x

Add 1 to the numerator and denominator   →     (x - 5 + 1)/(x + 1) = 1/2

Cross Multiply:                   1(x + 1) = 2(x - 4)

Distribute:                             x + 1 = 2x - 8

Subtract x from both sides:       1 = x - 8

Add 9 to both sides:                  9 = x

Numerator:  x - 5    →     9 - 5 = 4

Denominator:  x     →     9

So the fraction is: 4/9

Answer:

1/5 (one fifth)

Step-by-step explanation:

if x is the length of the bedroom and y is the width then we can do big brain maffs

Length of floor = x

Width of floor = y

Length of bed = 3/5*x or 3x/5

Width of bed = 1/3*y or y/3

Area of floor = xy

Area of bed = 3x/5 * y/3 = xy/5

Area of bed/Area of floor = (xy/5) / xy = 1/5

Answer:

(- 5, 0 )

Step-by-step explanation:

A translation of 1 unit left means subtract 1 from the x- coordinate.

A translation of 2 units down means subtract 2 from the y- coordinate.

(- 4, 2 ) → (- 4 - 1, 2 - 2 ) → (- 5, 0 )

The translated coordinate is (-5, 0).

A transformation known as a translation involves shifting each point in a figure by the same amount and in the same direction.

Translation is the act of moving a shape or a figure from one location to another. A figure can move in translation up, down, right, left, or anywhere else in the coordinate system. Only the object's position changes during translation; its size stays the same.

Given:

Image point (-4, 2)

And, now we have to translate the figure left 1 unit and down 2 units

So, A translation of 1 unit left means subtract 1 from the x- coordinate.

and translation of 2 units down means subtract 2 from the y- coordinate.

Thus, (- 4, 2 ) ----> (- 4 - 1, 2 - 2 ) ----> (- 5, 0 )

Hence, the translated coordinate is (-5, 0).

Answer:

400 seconds

Step-by-step explanation:

150/20=7.5 meters per second

3000/7.5=400 seconds

Priya will take 400 seconds to cover distance of 3,000 meters.

In unit time, the distance covered by any object is called speed.

In mathematical term, Speed is express as S=D/T,

where S=speed, D=distance, T= time.

Given that,

Distance covered by Priya in 20 seconds = 150 meters.

The speed of Priya = 150 / 20 = 15/2 meters per second

To find the time to cover the distance of 3,000 meter,

Use formula,

Time = distance / speed

Time = 3,000 / (15/2)

Time = 400 seconds

To cover 3,000-meter distance, Priya will take 400 seconds.

Answer:

x = 73

Step-by-step explanation:

so a circle is 360degrees,

the components that make up the 360 degrees are given, so form an equation and solve

295 + 38 + x - 46 = 360

solve with inverse operations and simplifying

295 + 38 + x - 46 = 360

-295                        -295

38 + x - 46 = 65

-38               -38

x  - 46 = 27

   + 46   +46    

x = 73

Step-by-step explanation:

Answer:

Step-by-step explanation:

If two line 'm' and 'n' are parallel and a transversal line 't' i intersecting these lines at two distinct points,

Sum of interior consecutive angles should be 180°.

(Property of the angles formed between parallel lines and a transversal line)

Therefore, 114° + 64° = 180°

178° = 180°

Which is not true.

Therefore, lines 'm' and 'n' are not the parallel lines.
