A system of two equations is shown below: Equation C: a = 3b + 6
Equation D: a = 7b − 1
What value of a can be substituted into equation D to solve the system of equations?
A. 3b
B. 7b
C. 3b + 6
D. 7b − 1

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..

45

step-by-step explanation:

13cm

step-by-step explanation:

(apex)

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
