Hello there!

4(2x + 1) - 3 = -3(x - 4)

We need to distribute both sides

(4)(2x) + (4)(1) - 3 = (-3)(x) + (-3)(-4)

8x + 4 - 3 = -3x + 12

8x + 1 = -3x + 12

Now subtract 1 from both sides

8x + 1 - 1 = -3x + 12 - 1

8x = -3x + 11

Add 3x to both sides

8x + 3x = -3x + 11 - 3x

11x = 11

x = 11/11

x = 1

I hope this helps~!

Good luck with your career!

Answer:

$\frac{53}{6}$

Step-by-step explanation:

$\int\limits^4_3 {x^2-x} \, dx$

= [ $\frac{x^3}{3}$ - $\frac{x^2}{2}$ ] ← evaluate for upper limit - lower limit

= ( $\frac{64}{3}$ - $\frac{16}{2}$ ) - ( $\frac{27}{3}$ - $\frac{9}{2}$ )

= $\frac{64}{3}$ - 8 - 9 + $\frac{9}{2}$

= $\frac{155}{6}$ - 17

= $\frac{53}{6}$

What is the y intercept of 60x+55y=660 [with work shown]

adelina 88 [10]

Answer:

(11, 0)

Step-by-step explanation:

to find the y intercept, set y to 0.

60x + 55y = 660

60x + 55 * 0 = 660

60x = 660

60x/60 = 660/60

x = 11

y intercept is (11, 0)
