Answer:

-4

Step-by-step explanation:

We know it's a linear equation and the slope is a whole number. Using point slope form we will write the equation:

y - y1 = m (x - x1) in which y1 is -7, m is 3, and x1 is -1

y - (-7) = 3(x-(-1))

y+7 = 3(x+1)

y+7 = 3x +3

Change to slope-intercept form:

y = 3x + 3 - 7

y = 3x = -4

the y intercept is -4

Han and Priya were making a kite. Han cut out a piece of fabric so

Lemur [1.5K]

A kite is a quadrilateral which has two equal adjacent sides. Therefore measuring the lengths accurately would make the pieces of wood perpendicular. Since the diagonals of a kite are at right angle to each other.

Quadrilaterals are shapes which has four straight sides. Examples are; square, trapezium, kite, rectangle etc.

A kite is a shape which has adjacent sides to have equal lengths. It has two diagonals, and one line of symmetry.

The lengths of the sides of the fabric being exact imply that the pieces of wood would be perpendicular as suggested by Priya when fixed appropriately to the piece of fabric. This is because the diagonals of a kite are always perpendicular. Thus measuring the angles as suggested by Han is not necessary.

A number divided by 40 has a quotient of six with the remainder of 16

djverab [1.8K]

So a number (x because unknown) divided by 40 (x divided into 40 parts or x/40) has a quotient of 6 with a remainder of 16 (answer=6 with 16 remainder)

remember that remainder is not involved in division, just leftover
x/40=6+16 remainder
to get rid of the fraction, multiply the whole equation by 40 and add the remainder (since it wasn't involved in division)
x=240+16
x=256
check: use calculator/head

number=256
