Find the point below that lies on the line y-7=4(x-2)
Phantasy [73]

Step-by-step explanation:

y-7=4(x-2)

we need to simplify the y to het a

y-7=4x-8 (i did 4x-8 because of 4(x-2)

now y= 4x-8+(-7)

after calculating -8+(-7) IT becomes

y=4x-15

okay we have the guide Line

y=4x-15

the a is 4

because

a = {y=a.x+b}

now we need to find the points using this guide Line

y=4x-15

x= 2(you can add any number here ,we Just need to know where the point is )

y= 4(2)-15

y=8-15

y= -7

points are (2,7)

Riya is applying mulch to her garden. she applies it at a rate of 250 , 000 cm 3 250,000 cm 3 250, comma, 000, start text, space
Tatiana [17]

The rate in

\frac{ {m}^{3} }{ {m}^{2} }  \: is \:0.25\frac{ {m}^{3} }{ {m}^{2} }

<h3>How to find rate is riya applying mulch in m^3/m^2 ?</h3>

given that riya applies it at a rate of 250,000 cm^3 of mulch for every m^2 of garden space.

we already know that 1m = 100cm.

so, each side of this cube is 100cm in length.

so,100 \times 100 \times 100 \: {cm}^{3}  \: in \:  {m}^{3}

To find what is the volume in cubic metres.

\frac{250000}{10000000}  =  \frac{1}{4}  = 0.25 \frac{ {m}^{3} }{ { m}^{2} }

so, the rate is0.25 \frac{ {m}^{3} }{ {m}^{2} }

Geometry proofs<br> help me please :)
REY [17]

Answer:

2) Right angles always equal 90°

3) m∠F = 90° and m∠G = 90° which means they have the same angle measure.

4) Removing the m and replacing with the congruent symbol.

I'm not too sure how this goes but it should be something like that.
