The slope-intercept form of the equation for a line with a slope of -4 and a y-intercept of -2 is ...
y = -4x -2
Answer:
C
Step-by-step explanation:
1)Non- zeros (1,2,3,....) are always significant.
2)Captive zeros are significant too( zeros between non- zeros ).
3)Trailing zeros (zeros at the end) aren't significant always unless if there is a decimal point.
Such this question we have decimal point so we count them
Answer:
33
Step-by-step explanation:
-66 / (-3 + -4 - -5)
That equals to
-66 / (-3 -4 + 5)
That equals to
-66 / -2
That equals to
33.
1) To graph y = 2x +3, give 2 different value for x & find its related y value:
for instance if x = 0 , then y = 3
if x = 1, then y = 5
Plot The coordinates of A(90,3) & B(1,5). You need just 2 point to draw a line.
2) The inverse of y=2x+3
a) Switch the x & y ===> x=2y+3
b) subtract 3 from both sides ===> x-3=2y+3-3===> x-3 = 2y
c) divide both sides by 2 ===> (x-3) / 2 =2y / 2 ==> 1/2(x-3)=y
And the inverse function of y = 2x+3 is y= 1/2(x+3)
