Find MN

LM = 3y + 4
MN = 7y + 9
LN = 143

Let's solve your equation step-by-step.

3x−5x+14=26

Step 1: Simplify both sides of the equation.

3x−5x+14=26

3x+−5x+14=26

(3x+−5x)+(14)=26(Combine Like Terms)

−2x+14=26

−2x+14=26

Step 2: Subtract 14 from both sides.

−2x+14−14=26−14

−2x=12

Step 3: Divide both sides by -2.

−2x

−2

=

Answer:

The difference between the times is just 6.09

Step-by-step explanation:

Here, we are interested in finding the difference between the times when two athletes finished their races.

While one finished at 24.53, the other finished at 18.44; So the difference between the two will be calculated by subtracting the time which was less from the time which was more;

Mathematically, that would be 24.53 - 18.44 = 6.09

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 3}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{ - 4x + 1 = 2x - 17}[/tex]

Move 2x to left hand side and change it's sign

Similarly, move 1 to right hand side and change it's sign

[tex] \dashrightarrow{ \sf{ - 4x - 2x = - 17 - 1}}[/tex]

Collect like terms

[tex] \dashrightarrow{ \sf{ - 6x = - 17 - 1}}[/tex]

The negative integers are always added but posses the negative ( - ) sign

[tex] \dashrightarrow{ \sf{ - 6x = - 18}}[/tex]

Divide both sides by -6

[tex] \dashrightarrow{ \sf{ \frac{ - 6x}{ - 6} = \frac{ - 18}{ - 6}}} [/tex]

Calculate

[tex] \dashrightarrow{ \sf{x = 3}}[/tex]

36 + 26(2) =

36 + 52 =

88

Answer:

88

Step-by-step explanation:

Given

d² + 26f , substitute d = 6 and f = 2 into the expression

= 6² + 26(2)

= 36 + 52

= 88

Answer:

c = -1

Step-by-step explanation:

6 - (3 - c) = 2

6 - 3 + -(-c) = 2

3 + c = 2

c = 2 - 3

c = -1

Check:

6 -(3-(-1)) = 2

6 - (3+1) = 2

6 - 4 = 2

Answer:

C=-1

The coordinates of the midpoint will be (-2,-3).

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

A midpoint is a point that lies on a line connecting two other locations and is in the middle of the line. Given that the midpoint of AB is M(3,-4) and the coordinates of A are (8, -5).

The midpoint will be calculated by using the formula below:-

( 8 + x ) / 2 = 3

( 8 + x ) = 6

x = -8 + 6 = -2

( -5 + y ) / 2 = -4

( -5 + y ) = -8

y =  -8 + 5 = -3

Therefore, the coordinates of the midpoint will be (-2,-3).

Step-by-step explanation:

sec (thita) = squrt (5)

squaring on both sides:

sec^2 (thita) = 5 - equation 1

1 + tan^2 (thita) = 5

tan^2 (thita) = 4

tan (thita) = 2.

= tan (thita) - squrt(5)sin(thita)

= 2 - squrt(5) x 2/ squrt(5)

= 0

from eqn - 1

sec(thita) = squrt(5)

cos(thita) = 1/ squrt(5)

sin(thita) = squrt ( 1- 1/(squrt (5))^2)

sin(thita) = 2/ squrt(5) .

Answer:

The numbers or measurements being compared are called the terms of the ratio. A rate is a special ratio in which the two terms are in different units. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.

Step-by-step explanation:

Answer:

Unit rate is used to compare quantities in which the second quantity is one. Common examples of unit rate would include, miles per hour earnings per hour cost per gallon.

Step-by-step explanation:

It's also your rise over run, remember to look at the unit of measurement when counting. Example, If rise over run is 1Mile/15min. That's a unit rate.

Step-by-step explanation:

Answer: L, J, K

Step-by-step explanation:

L, J, and K are collinear because they all lie on the same line.

Answer:

1,3

Step-by-step explanation:

Sorry if my English is bad

or if my answer is wrong but from my understanding,

as you can recognize from the photos, we need to understand what a collinear is. Collinear are points that are lying in the same straight line. Thus, we can transform the ratio to fractions which means 1 : 3 into 1/3

Hence, the coordinate R is 1/3 between P and S.

Therefore, to determine coordinate R, we must use the formula that is provided. P is (X1, Y1), S is (X2,Y2), M1 is 1 or the Numerator and M2 is 3 or The denominator.

Answer: Midpoint= (3,3)

Step-by-step explanation: Midpoint formula [tex]MP= (\frac{x_{1}+x_{2} }{2}), (\frac{y_{1}+y_{2} }{2} )[/tex]

[tex]MP= (\frac{8+-2 }{2}), (\frac{12+-6 }{2} )[/tex]

[tex]MP= (\frac{6 }{2}), (\frac{6 }{2} )[/tex]   6 divided by 2 = 3

[tex]MP= (3,3)[/tex]

Answer:

The answer is C, zero solutions.  

Step-by-step explanation:

y = 5/2x + 2

2y = 5x + 8

Multiply 2 to the first equation.  

2y = 5x + 4

Compare it with the other equation

2y = 5x + 4

2y = 5x + 8

Cancel 2y and 5x on both sides.  

Remaining:

4 = 8

4 ≠ 8.  Therefore, the answer is C, zero solutions.

Answer:

PQ = 1 ft

QR = 4 ft

Step-by-step explanation:

From the picture attached,

Segment PR has been divided into two parts by a point Q.

Length of segment PR = 5 feet

Length of segment PQ = (15x - 2) ft

Length of segment QR = (5x + 3) ft

Since, PR = PQ + QR

5 = (15x - 2) + (5x + 3)

5 = 20x + 1

20x = 4

x = [tex]\frac{4}{20}[/tex]

x = 0.2

PQ = 15x - 2

     = 15(0.2) - 2

     = 3 - 2

     = 1 ft

QR = 5x + 3

     = 5(0.2) + 3

     = 1 + 3

     = 4 ft
