The graph shows two lines, A and B:A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 3, 0 and the ordered pair 0, 6. Another straight line labeled B joins the ordered pair 0, 0 and the ordered pair 5, 5.

Based on the graph, which statement is correct about the solution to the system of equations for lines A and B?

A (0, 6) is the solution to both lines A and B.
B(0, 6) is the solution to line B but not to line
C(2, 2) is the solution to both lines A and B.
D (2, 2) is the solution to line A but not to line

Answers

The correct answer for the question that is being presented above is this one: "A (0, 6) is the solution to both lines A and B." The statement that is correct about the solution to the system of equations for lines A and B is that (0, 6) is the solution to both lines A and B.

Answer:

C(2, 2) is the solution to both lines A and B.

Step-by-step explanation:

Line A is given as:

A straight line labeled A joins the ordered pair 3, 0 and the ordered pair 0, 6.

We know that the equation of a line passing through (a,b) and (c,d) is calculated as:

$y-b=(d-b)/(c-a)* (x-a)$

Hence, the equation of line is:

$y-0=(6-0)/(0-3)* (x-3)\n\ny=(6)/(-3)* (x-3)\n\ny=-2* (x-3)\n\ny=-2x+6$

Hence, equation of line A is:

$y=-2x+6$

Similarly B is a line passing through (0,0) and (5,5).

Hence, the equation of line B is:

$y=x$

So, from the graph we observe that, the point of intersection of the two lines is (2,2).

Thus, option C is correct.

How to solve linear equations by substitution?

5x+2y=9
x+y=-3

Answers

5x+2y=9 x+y=3

change x+y=3 into x=3-y

plug that equation into 5x+2y=9 where x is.

5(3-y)+2y=9

then distribute.

15-5y+2y=9

15-7y=9

minus 15.

-7y=-6

divide both sides by -7.

y is equal to -6/7.

then go back to the first equation and plug in for y.

and then you will get x.

then you will have (y,x)

$\begin{cases} 5x+2y=9 \n x+y=-3\end{cases} \n \n\begin{cases} 5x+2*(-3-x)=9 \n y=-3 -x\end{cases} \n \n\begin{cases} 5x-6-2x =9 \n y=-3 -x\end{cases}\n \n\begin{cases} 3x =9+6 \n y=-3 -x\end{cases}$

$\begin{cases} 3x =15 \ \ /:3 \n y=-3 -x\end{cases} \n \n\begin{cases} x =5 \n y=-3 -5\end{cases} \n \n\begin{cases} x =5 \n y=-8\end{cases}$

B. rhombus-4 equal sides
C. squaer - 4 equal sides and 4 right angles (both a rhombus and rectangle)
D. kite. 2 pairs of paralell sides that are next to each other (looks like a kite)

5. 4 equal sides, no right angle: rhombus
6. 4 right angles, all sides equal legnth:squaer
7. 1 pair of paralel sides:trapezoid
8. 4 right angles:rectangle
9. if a rectangle has 4 equal sides it is technically a squaer and a rhombus
all squares are recangles and rhombuses, but not all rhombuses and rectangles are squaers

5. rhombus
6. square
7. trapezoid
8. rectangle
9. it is has 4 equal sides, then yes

Solve 10^6x=93. round to the nearest ten thousand.A) 11.8109

B) 1.0986

C) 13.3801

D) 0.3281

Answers

10^(6x) = 93

10⁶ˣ = 93

Take the logarithm of both sides to base 10.

Log₁₀ 10⁶ˣ =Log₁₀ 93

6x * (Log₁₀ 10) = Log₁₀ 93

6x = (Log₁₀ 93) / (Log₁₀ 10)

By laws of logarithm Log₁₀ 10 = 1

6x = (Log₁₀ 93) / 1

6x = Log₁₀ 93 With Calculator Log₁₀ 93 ≈ 1.9685

6x ≈ 1.9685

x ≈ 1.9685/6

x ≈ 0.3281

Option D.

Hope this explains it.
