Answer: (2.6, 0.4), (3.6,0.6) is the solution of given equations.

Explanation: Given Functions are:

f(x)=log(x) and g(x)=|x-3|

Since, the solution of the above equations will be get after solving these two equations. Or we can say that, the intersection point of the curves made by the above equation is the solution of  the system.

After making the graph of functions f(x) and g(x)  we observed that, f(x) and g(x) are intersecting at points (2.587, 0.413) ≈(2.6,0.4) and (3.55,0.55)≈(3.6,0.6).

Thus, solution of f(x) and g(x) are (2.6,0.4) and (3.6,0.6).

Therefore, options first and fourth is correct.

Answer:

a=7,\\b=3

Step-by-step explanation:

The area of a rectangle is equal to A=l\cdot w, where l is the length of the rectangle and w is the width of the rectangle. In a rectangle, opposite sides are equal.

Therefore, we can write the following system of equations:

\begin{cases}a\cdot (9+b)=84,\\a\cdot b=21\end{cases}

Expand the first equation:

9a+ab=84

Substitute the second equation into the first (ab=21):

9a+21=84,\\9a=63,\\a=\boxed{7}

Solving for b:

7b=21,\\b=\frac{21}{7}=\boxed{3}

I don’t understand this assignment!!

Answer:

Equation of the Line: y = 1.25x + 5

Equation in Standard Form: 5x - 4y = -20

Step-by-step explanation:

y = mx + b

\frac{17.5 - 22.5}{10 - 14} = \frac{-5}{-4} = \frac{5}{4} or 1.25

y = 1.25x + 5

Ax + By = C  (A must be positive, and no fractions or decimals)

y = 1.25x + 5

-1.25x + y = 5

times -4

5x - 4y = -20

A board 1.2 m long is cut into two so that the length of the longer piece is 15cm longer than twice the length of the shortest p
MAXImum [283]

Answer:

The length of the shorter piece=0.35 m

Step-by-step explanation:

Let the lengths be as follow;

Shorter piece=x

Longer piece=15 cm longer than twice shorter piece(x)

Since 1 m=100 cm, 15 cm=15/100=0.15 m

Longer piece= (2×x)+0.15=2x+0.15

Total length=1.2 m

Total length=shorter piece+longer piece

Replacing;

1.2=x+2x+0.15

3x=1.2-0.15

3x=1.05

x=(1.05/3)=0.35

The length of the shorter piece=x=0.35
