Find the slope of the line y=-1/4x+9
Basile [38]

Answer:

slope = - \frac{1}{4}

Step-by-step explanation:

The equation of a line in slope0 intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - \frac{1}{4} x + 9 ← is in slope- intercept form

with slope m = - \frac{1}{4}

Solve. −1.2z− 8.2>−9.7 Drag and drop a number or symbol into each box to show the solution. <>1.25 1.5 −1.25 −1.5
Varvara68 [4.7K]
The correct answer is: x < 1.25

To solve this, we following the same steps as when solving inequalities. We just have to remember to reverse the sign if we multiply or divide by a negative number.

-1.2x - 8.2 > -9.7
-1.2x > -1.5
x < 1.25

The expression into a single logarithm is log[(x)^{10}][(2)^{30}]

Step-by-step explanation:

Let us revise some logarithmic rules

  • log(a)^{n}=nlog(a)
  • log(ab)=log(a)+log(b)
  • nlog(a)+mlog(b)=log[(a)^{n}][(b)^{m}]

∵ 10 log(x) + 5 log(64)

- At first re-write 10 log(x)

∴  10 log(x) = log(x)^{10}

- Then re-write 5 log(64)

∴  5 log(64) = log(64)^{5}

∴ 10 log(x) + 5 log(64) = log(x)^{10} + log(64)^{5}

- Use the 3rd rule above to make it single logarithm

∵ log(x)^{10} + log(64)^{5} = log[(x)^{10}][(64)^{5}]

∴ 10 log(x) + 5 log(64) = log[(x)^{10}][(64)^{5}]

∵ 64 = 2 × 2 × 2 × 2 × 2 × 2

∴ We can write 64 as 2^{6}

∴ (64)^{5}=(2^{6})^{5}

- Multiply the two powers of 2

∴ (64)^{5}=(2)^{30}

∴ 10 log(x) + 5 log(64) = log[(x)^{10}][(2)^{30}]

The expression into a single logarithm is log[(x)^{10}][(2)^{30}]
