Answer:

y = 2 x – 5

Step-by-step explanation:

We can check all of them starting with equation 1.

y = x + 3

3 = 4 + 3

3 = 7

NOT TRUE

Equation 2:

3 = 3(4) - 4

3 = 12 - 4

3 = 8

NOT TRUE

Equation 3:

3 = 2(4) - 5

3 = 8 - 5

3 = 3

TRUE!

This means the last equation is not true.

Answer:

The pine is 12 m tall and the fir is 12 m tall

Step-by-step explanation:

System of Equations

Let's call:

x = height of a pine tree

y = height of a fir tree

The combined height of one fir tree and one pine tree is 21 meters. This leads to the equation:

x + y = 21       [1]

The height of 4 fir trees is 24 meters taller than one pine tree:

4y = x + 24       [2]

From [1]:

x = 21 - y         [3]

Substituting in [2]:

4y = 21 - y + 24

Adding y:

5y = 45

Dividing by 5:

y = 9

Substituting in [3]:

x = 21 - 9 = 12

The pine is 12 m tall and the fir is 12 m tall

What is logarithmic function?

A function of the form is a logarithmic function. "y equals the log of x, base b" or "y equals the log, base b, of x" is how it's written. x > 0 and b > 0, b 1 in both versions. y is not restricted in any way.

How to solve?

Answer:

A. 45°

Step-by-step explanation:

By exterior angle theorem:

x + 70° = 115°

x = 115° - 70°

x = 45°

Answer:

x= 45°

Step-by-step explanation:

triangles degrees all together are always 180°

x≠180°

a straight line is also 180°

180°-115°= 65°

70°+65°= 135°

180°-135°= 45°

Answer:

Answer:

10000 units of impact

Step-by-step explanation:

From the above question:

12 mph = 4000 units of impact

30 mph = x units of impact

Cross Multiply

12 mph × x units = 30 mph × 4000 units

x units = 30 mph × 4000 units/12 mph

x units = 10000 units of impact.

Therefore, 30 mph receives 10000 units of impact

Answer: All real numbers are solutions.

Step-by-step explanation:

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

2(3x−1)=6x−2

Step 1: Simplify both sides of the equation.

2(3x−1)=6x−2

(2)(3x)+(2)(−1)=6x+−2(Distribute)

6x+−2=6x+−2

6x−2=6x−2

Step 2: Subtract 6x from both sides.

6x−2−6x=6x−2−6x

−2=−2

Step 3: Add 2 to both sides.

−2+2=−2+2
