4x-y=10 as coordinates

These are possible solutions (0,−10), (2,-2), (4,6), (6,14)

Step-by-step explanation:

If you put this on a graph (try desmos and put it on a graph) those points line up with the equation.

Sorry if it doesn't help.

11/4 in decimal form 2.75

Step-by-step explanation: 4x−y=10

4x−y=10

Step 1: Add y to both sides.

4x−y+y=10+y

4x=y+10

Step 2: Divide both sides by 4.

4x/4=y+10/4

x=1/4y+5/2 = 11/4= 2.75

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm
