Answer:

gradient = -1

Step-by-step explanation:

identify the y intercept ( the point where it meet the y- axis ) which denoted by c in the formula y =mx + c

in the graph :the y- intercept is 5 (c)

take the coordinate of any point that passes through the line :- for example (2,3)

in (2,3), the value of x is 2

the value of y is 3

using the formula y = mx + c find m with is the gradient ( unknown )

y = mx + c

3 = m2 + 5

2m + 5 = 3

we sent + 5 to the right and it changes sign to become -5

2m = 3 -5

we substract -5 from 3

2×m = -2

we send 2 to the other side so that m can be alone, it change to become divide since it was multiply

m = -2 ÷ 2

m = -1

the gradient ( unknown ) = -1

Which exponential equation is equivalent to this logarithmic equation log x5 + log x12 =7
trapecia [35]

Answer:

x⁷ = 60

Step-by-step explanation:

<u>Given</u><u> </u><u>:</u><u>-</u><u> </u>

  • log x⁵ + log x ¹² = 7 .

<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u><u> </u>

  • The expotential equation .

<u>Solution</u><u> </u><u>:</u><u>-</u><u> </u>

Given logarithmic equation is ,

⇒ log x⁵ + log x ¹² = 7

⇒ log x ⁵ * ¹² = 7 [ log aⁿ + log aⁿ' = log aⁿ * ⁿ' ]

⇒log x ⁶⁰ = 7

In expotential form we can write it as ,

⇒ x⁷ = 60
