Answer:

$y = \frac{4}{3} x +1$

Step-by-step explanation:

1: find the perpendicular gradient - this is the negative reciprocal of the original gradient:

$y=\frac{-3}{4}x+ 2 \\y=\frac{4}{3} x+c$

2: Substitute in the coordinate to find the value of c:

$y=\frac{4}{3}x +c\\5 = \frac{4}{3} (3) + c\\5 = 4+c\\c=1$

3: Put it all together:

$y=\frac{4}{3}x+1$

Expand. If necessary, combine like terms. (3 + 4x) (3 - 4x)

shepuryov [24]

(3 + 4x) (3 - 4x)

We know the algebraic identity: (a - b)(a + b) = a^2 + b^2. Therefore, we should square 3 and 4x.

= (3)^2 - (4x)^2
9 - 16x^2

Answer:

9 - 16x^2

PLEASE HELP ME, ILL BRAINLIEST YOU ill give u 30 points if you help

Answer:

$x = 58$

$y = 90$

Step-by-step explanation:

This is a rhombus becuase it a quadralterial and it has four right triangles, and it diagonals bisect each others so it cant be a trapezoid, and paralleolgram. and it doesnt have four right corner angles so it cant be a square or rectangle or kite.

A rhombus inner angle measure is 90 degrees.

$y = 90$

This means the upper left angle of the top triangle measure is 58 becuase triangle interior theorem.

Since a rhombus bisects angles, angle x measure 58.
