Solve the system of linear equations using elimination.

Mathematics
1 answer:
N76 [4]4 years ago
8 0

Answer:

C (-2,1)

Step-by-step explanation:

−2x − y = 3 (1)

−9x − y = 17 (2)

(1) y = -2x - 3

(2) y = -9x - 17

-2x - 3 = -9x - 17

7x = -14

x = -2

y = -2(-2) - 3

y = 4 - 3

y = 1

80 POINTS!!!!<br><br> Simplify 6 to the power of -3 over 6 to the power of 5
tigry1 [53]

6^-3 / 6^5

Because the numerator has a negative exponent, use the negative exponent rule b^-n = 1/b^n

To do this move 6^-3 to the denominator:

1 / (6^5 * 6^3)

When you multiply identical numbers with exponents you add the exponents so (6^5 * 6^3) becomes 6^8

Now you have 1 / 6^8

Now raise 6 to the power of 8 to get:

1/1679616

Depending on the format your answer needs to be in you have 3 different answers:

1) 1/6^8 ( Leaving it as an exponent)

2) 1 / 1679616 (As a fraction)

3) 5.9537 x 10^-7 (As a decimal, round as needed)

Write an equation of the line that passes through (2,-1) and is parallel to the graph of y = 5x – 2. Write your final equation i
slamgirl [31]

Answer:

The equation would be y = 5x - 11

Step-by-step explanation:

To find this line, start with the slope. Since it is parallel to the first line and parallel lines have the same slope, we know the slope to be 5. Given this we can use point-slope form and solve for y to get the equation.

y - y1 = m(x - x1)

y + 1 = 5(x - 2)

y + 1 = 5x - 10

y = 5x - 11
