Answer:
0
Step-by-step explanation:
8x + 4 = 3x - 3 +7
u first expand the bracket as I have done above
then u evaluate those who have like terms close like -3 + 7
8x + 4 = 3x + 4
then u group like terms ie. the values with the variable x on one side of the equation and the ones without x on the other side of the equation
8x - 3x = 4 - 4
8x - 3x = 0
5x = 0
then u divide both side by the coefficient of x
0/5 but any number divided by 0 is 0, so x = 0
Answer: b = -6
Step-by-step explanation:
-233 = 6(3+7b) +1
-233 = 18 + 42b +1
-233 - 18 - 1 = 42b
-252 = 42b
-252/42 = b
b = -6
Hello to Mr Fowler's science class from brainly!!!
I'm sorry but your question doesn't make sense. Maybe you worded it wrong.
Answer:
Step-by-step explanation:
A line goes through the points (-2, 4) and (8, 9). We see that x increases by 10 and y increases by 5.
Thus, the slope of this line is m = rise / run = 5/10 = 1/2 (the slope)
Starting with the point slope equation y - k = m(x - h) and substituting 9 for y, 8 for x and 1/2 for m, we get:
y - 9 = (1/2)(x - 8) (point-slope form)
y = (1/2)x + 5 (slope-intercept form)
