Answer:

x = 6

Step-by-step explanation:

Slope = (y(2) - y(1))/(x(2) - x(1))

(-1 - 1) / (-1 - x)

If the slope is 2/7, it would be (-2/-1-x, where x would have to be 6)

(-2)/(-7) = 2/7, so x = 6

Check:

(-1 - 1) / (-1 - 6)

(-2)/(-7)

2/7 (Correct :))

Hope it helps :D

TRUE OR FALSE? The equation of a line with slope m = -3 and including point (5, 5) is y = -3x + 20.

kodGreya [7K]

Answer:

True.

Step-by-step explanation:

y = -3x + 20

Put x as 5, then y output should be 5.

y = -3(5) + 20

y = -15 + 20

y = 5

True, the line with slope -3 passes through points (5, 5).

Solve the inequality 3x - 5 < 4.

Pachacha [2.7K]

Answer:

x < 3

Step-by-step explanation:

Since 3x - 5 < 4 then we can transpose the inequality to make x the subject of the equation:

If 3x - 5 < 4

⇒ 3x < 4 + 5

⇒ x < 9 ÷ 3

⇒ x < 3

Simplify quantity 10 x squared minus 32 end quantity over 4 quantity 5 x squared minus 32 end quantity over 2, quantity 5 x squa

irina1246 [14]

Answer:

Option B.

Step-by-step explanation:

The given expression is

$\dfrac{10x^2-32}{4}$

We need to find the simplified form of given expression.

Taking out GCF from the numerator.

$\dfrac{2(5x^2-16)}{4}$

Cancel out common factors.

$\dfrac{5x^2-16}{2}$

The expression $\dfrac{5x^2-16}{2}$ is the simplified form of given expression.

Therefore, the correct option is B.
