Answer:

1.

Step 1: Flip the equation.

4x−6=y

Step 2: Add 6 to both sides.

4x−6+6=y+6

4x=y+6

Step 3: Divide both sides by 4.

4x

=

y+6

2.

Step 1: Add 4y to both sides.

5x−4y+4y=−9+4y

5x=4y−9

Step 2: Divide both sides by 5.

5x

5

=

4y−9

Answer:

a¹⁸b²⁴c⁵⁴

Step-by-step explanation:

(aᵇ)ᶜ = aᵇᶜ = aᵇ×ᶜ

(-aⁿ)ᵒᵈᵈ = -aⁿ

(-aⁿ)ᵉᵛᵉⁿ = aⁿ

aⁿ × aⁿ = aⁿ⁺ⁿ

_________

In this situation, 6 is an even exponent which means that the negative coefficient of this 9th degree monomial will be positive. Now the only step is to multiply the exponents by the exponent outside of the perenthesis which is 6.

so (-a³b⁴c⁹)⁶ = ((-a³)⁶(b⁴)⁶(c⁹)⁶) = ((a³ˣ⁶)(b⁴ˣ⁶)(c⁹ˣ⁶)) = ((a¹⁸)(b²⁴)(c⁵⁴)) = <em>a¹⁸b²⁴c⁵⁴</em>

PLEASE HELPPP i would really appreciate it :)
qaws [65]

Answer:

Y = - 12.55X1 + 276.52

Step-by-step explanation:

Given the data:

Age of child :(X) : 4, 6, 10, 13, 14, 17

Time (seconds) (Y) : 230, 205, 132, 119, 108, 62

Using technology, the linear regression equation obtained using the data Given is :

Y = - 12.55X1 + 276.52

Where :

Slope = - 12.55

Intercept = 276.52

This also indicates that a negative slope is present and hence a negative relationship between age of Child and time in seconds.

Solve for the value of k. (k+8) 400​
pashok25 [27]

Answer:

value of k = 6

Step-by-step explanation:

sum of all angles forming a straight line = 180°

so,

  • 7k + 8 + 90 + 40 = 180
  • 7k + 138 = 180
  • 7k = 180 - 138
  • 7k = 42
  • k = 42/7
  • k = 6

hence the value of k = 6
