Graph y = 4x - 1. When x = -2, what is the ordered pair of the solution?

Mathematics

(-9, -1)

(-9,-1) . -1 because that is the y intercept from the equation.

-9 because when you substitute -2 for x, and multiply by 4, you get -8. Then you subtract one, making the x value -9.

Therefore, the ordered pair of the solution is (-9,-1)

Hope this helps, please consider marking branliest if it did.

Solve the system and give your answer as a coordinate point in the form (k, c) k+c=100 51k+11c=2500
Aleks [24]

Answer:

k = 35, c = 65

Step-by-step explanation:

Solve the following system:

{c + k = 100 | (equation 1)

{11 c + 51 k = 2500 | (equation 2)

Swap equation 1 with equation 2:

{11 c + 51 k = 2500 | (equation 1)

{c + k = 100 | (equation 2)

Subtract 1/11 × (equation 1) from equation 2:

{11 c + 51 k = 2500 | (equation 1)

{0 c - (40 k)/11 = -1400/11 | (equation 2)

Multiply equation 2 by -11/40:

{11 c + 51 k = 2500 | (equation 1)

{0 c+k = 35 | (equation 2)

Subtract 51 × (equation 2) from equation 1:

{11 c+0 k = 715 | (equation 1)

{0 c+k = 35 | (equation 2)

Divide equation 1 by 11:

{c+0 k = 65 | (equation 1)

{0 c+k = 35 | (equation 2)

Collect results:

Answer: {c = 65 , k = 35

Need to use the properties of exponents to solve this equation. I'm a bit confused on how to do this problem so a step by step d
garik1379 [7]

Answer:

Step-by-step explanation:

The given expression is

(4×10^8)(4×10^-7)/(4×10^8)

Considering the property of exponents which is expressed as

y^a × y^b = y^(a + b)

Applying the above rule to the denominator of the given expression, it becomes

4×10^8 × 4×10^-7 = 16 × 10^(8 + - 7)

= 16 × 10^(8 - 7)

= 16 × 10 = 160

The expression becomes

16 × 10/(4×10^8)

We would apply the property of exponents which is expressed as

y^a ÷ y^b = y^(a - b)

It becomes

16/4 × 10^(1 - 8)

= 4 × 10^-7
