Solve the equation 40 = -10(y+0.3). what does the y equal​
alexdok [17]

Answer:

y = -4.3

Step-by-step explanation:

40 = -10(y + 0.3) <em>{Step 1: Use the distributive property to multiply -10 by y + 0.3}</em>

40 = -10y + -10(0.3)

40 = -10y - 3 <em>{Step 2: Add 3 to both sides.}</em>

40 + 3 = -10y

43 = -10y <em>{Step 3: Divide both sides by -10}</em>

43/-10 = y

-4.3 = y

y equals -4.3.

Simplify (3x+2)(x-7)
vovangra [49]
The answer is
3 {x}^{2}  - 19x - 14
first you must multiply or use the FOIL method (First, Outer, Inner, Last)
First you multiply the first terms
(3x)(x)
this gives you 3x^2, then you multiple the outer terms
( - 7)(3x)
this gives you -21x, then you multiply the inner terms
(2)(x)
that gives you 2x, finally you multiply the last terms
(2)( - 7)
that gives you 14, now you combine like terms
- 21x + 2x =  - 19x
now you put all the terms together and end up with your solution
3 {x}^{2}  - 19x - 14
