Mathematics

1 answer:

Whitepunk [10]3 years ago

3 0

Answer:

n = {-1, 7}

Step-by-step explanation:

8n² - 56 = 48n

Subtract 48n from both sides

8n² - 48n - 56 = 0

Divide both sides by 8

n² - 6n - 7 = 0

Factor

alternately use the quadratic equation or complete the square

(n - 7)(n + 1) = 0

n = {-1, 7}

Which way do you move when a question is asking which pair is located 5 units from point F? Point F being (3,-2)

valina [46]

Answer:

Ann direction

Step-by-step explanation:

Given

$F = (3,-2)$

Required

Move 5 points from F

Generally, the direction to move the point is always stated. Since none is stated in this question, you can move the point in the positive or negative direction of the x and y coordinates (in other words, any direction).

So, the possible locations are:

$(3 + 5, -2) = (8, -2)$

$(3 - 5, -2) = (-3, -2)$

$(3, -2+ 5) = (3, 3)$

$(3, -2- 5) = (3, -7)$

Each of the above points are 5 units away from F
