Find the point 3x - 7x₂ =5. of the lines x, - 5x2 = 1 and of intersection

tia_tia [17]

Answer:

( $\frac{9}{4},\frac{1}{4})$

Step-by-step explanation:

We are given that two lines

$x_1-7x_2=5$ and $x_1-5x_2=1$

We have to find the intersection point of two lines

Let $3x_1-7x_2=5$ (equation 1)

$x_1-5x_2=1$ (Equation 2)

Multiply equation 2 by 3 then subtract from equation 1

$-7x_2+15x_2=5-3$

$8x_2=2$

$x_2=\frac{2}{8}=\frac{1}{4}$

Substitute $x_2=\frac{1}{4}$ in the equation 1

Then, we get

$3x_1-7\frac{1}{4}=5$

$3x_1-\frac{7}{4}=5$

$3x_1=5+\frac{7}{4}=\frac{20+7}{4}=\frac{27}{4}$

$x_1=\frac{27}{4\times 3}=\frac{9}{4}$

Hence, the intersection point of two given lines is ( $\frac{9}{4},\frac{1}{4})$

Ayden wrote 54.077 as the standard form for fifty-four and seventy-seven hundredths. Is he correct? Explain.

cestrela7 [59]

Answer:

No, Ayden is incorrect

Step-by-step explanation:

Because the last 7 is in the thousandth place so therefore he is wrong, but this would be the correct answer 54.77 since the last 7 is in the hundredth place.
