A line passes through the point (-3, -3) and has a slope of 1/2. What is the equation of the line? A y= 1/2x + 3/2 B y= 1/2x -3/

garik1379 [7]

Answer:

$(B.) y= 1/2x -3/2$

Step-by-step explanation:

$(-3, -3) = (x_1,y_1)\\m = 1/2\\\\y-y_1=m(x-x_1)\\\\y -(-3)=\frac{1}{2} (x -(-3)\\\\y+3 = \frac{1}{2}(x+3)\\\\ y+3 = \frac{1}{2} x+\frac{3}{2}\\\\ y = \frac{1}{2} x +\frac{3}{2} -3\\\\y = \frac{1}{2} x - \frac{3}{2}$

For what value of r is the parallelogram a rhombus

Gre4nikov [31]

Answer:

9

Step-by-step explanation:

7r+18=r²

r²-7r-18=0

factorizing

r²+2r-9r-18=0

r(r+2)-9(r+2=0

(r-9)(r+2)=0

r-9=0

r=9

check

(r²)=(9*9)=81

7r+18=7(9) + 8=81

How to show opposite sides on a parallelogram are congruent

Marta_Voda [28]

Answer:

I am attaching a image to understand my proof.

Step-by-step explanation:

PROVE:-

AB = DC

AD = BC

∠ ABD = ∠ BDC (alternate angles are equal )

∠ DBC = ∠ ADB (alternate angles are equal )

∴ Δ ADB ≅ Δ CBD ( by ASA rule )

DC = BA ( corresponding sides of ≅ Δ )

AD = CB ( corresponding sides of ≅ Δ )

Hence it is proved that opposite sides of parallelogram are congruent )
