What is the slope of a vertical line?

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x−2−7x=10x+4

3x+−2+−7x=10x+4

(3x+−7x)+(−2)=10x+4(Combine Like Terms)

−4x+−2=10x+4

−4x−2=10x+4

Step 2: Subtract 10x from both sides.

−4x−2−10x=10x+4−10x

−14x−2=4

Step 3: Add 2 to both sides.

−14x−2+2=4+2

−14x=6

Step 4: Divide both sides by -14.

−14x−14=6−14

x=−3/7

Answer:

x=−3/7

The  value of x is -3/7.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

3x-2-7x = 10x + 4

Now, solving for x

3x-2-7x = 10x + 4

-4x - 2= 10x + 4

-4x - 10x = 4 + 2

-14x = 6

x= -6/14

c= -3/7

Hence, the value of x is -3/7.

Answer: m∠PQR = 134°

Step-by-step explanation:

Given:  PS is line segment. Q is the point between segment PS. QR is another line segment passes through segment PS.

That means ∠PQR and ∠SQR are linear pair  [Linear pair is a pair of two angles made on one line and their sum is 180°]

⇒  ∠PQR +  ∠SQR  = 180°  (i)

Since, ∠PQR is (3x + 5)° and ∠ SQR is (x + 3)°   [given]

Put this in (i), we get

(3x + 5)° + (x + 3)° = 180°

⇒ 3x + 5 + x + 3 = 180

⇒ 4 x + 8 = 180

⇒ 4 x = 180-8

⇒ 4 x = 172

Divide both sides by 4

⇒  x= 43

So,  ∠PQR=  (3(43) + 5)° = 134°

Hence, m∠PQR = 134°

The measure of m ∠PQR is 134 degrees.

PS is a line segment.

Q is the point between segment PS.

QR is another line segment that passes through segment PS.

The sum of two angles made on one line is equal to 180 degrees.

[tex]\angle \rm PQR + \angle SQR = 180[/tex]

Where the angle QPR is (3x + 5) degree and angle SQR is (x + 3) degree.

Substitute all the values in the equation

[tex]\angle \rm PQR + \angle SQR = 180\\\\(3x+5) + (x+3) =180\\\\3x+5+x+3=180\\\\4x+8=180\\\\4x=180-8\\\\4x=172\\\\x = \dfrac{172}{4}\\\\x =43[/tex]

The value of x is 43 degrees.

Therefore,

The measure of m ∠PQR is;

[tex]\rm m \angle PQR = 3x+5 = 3(43) + 5= 129+5=134[/tex]

Hence, the measure of m ∠PQR is 134 degrees.

Answer:

The coordinates of k are (-2,-1)

Step-by-step explanation:

Here, we are interested in calculating the coordinates of point k.

Mathematically, we will use the internal division formula for this;

This would be;

(x,y) =( nx1 + mx2)/(m + n), (ny1 + my2)/(m + n)

where m = 1 , n = 4

x1 = -2 , x2 = 8

y1 = -4 , y2 = 11

we now make the substitutions into the formula;

(x,y) = 4(-2) + 1(-2)/(1+4) , 4(-4) + 1(11)/(4 + 1)

(x,y) = (-8-2)/5 , (-16 + 11)/5

(x,y) = -10/5 , -5/5

(x,y) = (-2, -1)

Answer:

Answer:

So, cost of 1 pair of shorts =$12

Step-by-step explanation:

Let cost of 1 pair of jeans =x

Cost 1pair of shorts =y

cost of 1 pair of shirts=z

We can set up equations as

x+4 y+2 z=84

2 x+1 y+3 z=76

x+2 y+z=52

Solve the equations for y.

Take first and second equations multiply first equation by -2 and add it with second equation.

-2 x-8 y-4 z=-168

2 x+1 y+3 z=76

Add them, it gives -7 y-z =-92

Now, take second and third equations, multiply the third equation by -2 then add them together.

2 x +1 y +3 z =76

-2 x-4 y-2 z=-104

Add them together,

-3 y +z =-28

Now, take the -7 y -z =-92 and -3 y +z =-28

Add the equations

-10 y = -120

Divide both sides by -10

y =12.

So, cost of 1 pair of shorts =$12

z=8

It will take 6 weeks for you and your friend to have the same balance.

First, you must set up your equation, with [tex]x[/tex] representing the amount of weeks

until you and your friend have the same balance.

[tex]121+12x=91+17x[/tex]

Then, you must subtract 91 on both sides.

[tex]30+12x=17x[/tex]

Next, subtract 12x on both sides.

[tex]30=5x[/tex]

Finally, divide 5 on each side

[tex]x=6[/tex]
