Answer:

<h3>The lines are perpendicular</h3>

Step-by-step explanation:

We determine whether lines are parallel or perpendicular by getting their slopes

For line 1; (1, 0), (7, 4)

Slope m = 4-0/7-1

M1 = 4/6

M1 = 2/3

Hence the slope of M1 is 2/3

For Line 2; (7, 0) , (3, 6)

M2 = 6-0/3-7

M2 = 6/-4

M2 = -3/2

Take the product of the slopes

M1 * M2 = 2/3 * -3/2

M1M2 = -1

Since the product of their slope is -1, hence the lines are perpendicular

sammy [17]

There are 14 girls in class five.

<h3>How many of the students are girls?</h3>

28 students were present in class five, such that 18 of them were boys.

The number of girls on Sunday is given by the difference:

28 - 18 = 10

And we know that 4 girls did not go to school on that day, so the total number of girls on class five is:

10 + 4 = 14

WILL GIVE BRAINLYST DUE IN 20 MINS
Darina [25.2K]

Answer:

1. x = -7

2. y = -1

Step-by-step explanation:

1.

-3x - 5 = 16              add 5 to both sides

-3x = 21                    divide -3 to both sides

x = -7

2.

-4(y-2) = 12             distribute -4

-4y + 8 = 12             subtract 8 from both sides

-4y = 4                divide -4 to both sides

y = -1
