Answer:

y=3x+5

Explanation:
Taking two coordinates
(-1,2). (0,5)
Solving for the slope (m) by using its rules
m= y2-y1/x2-x1
m= 5-2/0-(-1)
m= 3/1 =3

Solving for b
y=mx+b
2=3(-1)+b
2=-3+b
+3. +3
5=b

I hope this makes m sense by any chance :)

Leanne multiplied 8 x 4.3 and got 32.24. Is Leanne correct?Use an area model to explain your answer
dlinn [17]

Answer:

No, not correct.  

Step-by-step explanation:

Note that 8 * 4.3 can be broken up as follows:

8 * (4 + 0.3)

and that 4*8 =32, and that 0.3(8) = 2.4 (not 0.24).

Then 8 * (4 + 0.3) becomes 32 + 2.4 = 34.4

X^2+ 6x - 4 = 3x + 6
jolli1 [7]

Answer:

x=2

x=-5

Step-by-step explanation:

You need to get everything on one side to have a quadratic equation:

x^2+6x-4 -(3x+6) = x^2+3x-10

All factors of 10 are 1*10 and 2*5.

5-2 = 3 and 5*-2 = -10

Factoring x^2+3x-10 gives us (x-2)(x+5)

x=2

x=-5
