Y = - 2/3x + c , ( -9 , 7 )
7 = - 2/3 ( - 9 ) + c
c = 13
y = - 2/3x + 13
i am a mathematics teacher. if anything to ask please pm me
It is understood without being written that the slope of this line is 1. If we rewrite the point-slope form of the line it would be y-8=1(x-4) where 1 is the slope. We move the -8 over by addition to get y = 1x-4+8, or, simplified, y=x+4, the first choice in your answers.
Answer:
blue question mark = –
Step-by-step explanation:
6(2x -1) uses the distributive property, which means that both 2x and -1 are multiplied by 6 when expanding the brackets.
6(2x - 1)
= (6 x 2x) + (6 x -1)
= 12x - 6

b. FALSE.❌
c. FALSE❌
d. TRUE.✅
Step-by-step explanation:
To determine if each statement is true or not, let's find the slope/unit cost of each lotion.
Slope of lotion C using a point of line C, (6, 3):
Slope/unit cost = y/x = 3/6 = $0.50 per oz
Slope of lotion D using a point of line D, (4, 3):
Slope/unit cost = y/x = 3/4 = $0.75 per oz
Now let's determine whether each statement given is true or false:
a. Statement A is TRUE. Lotion C cost $0.50 per oz ✅
b. Statement B is FALSE. Lotion D cost $0.75 per oz not $2.00 per oz.❌
c. Statement C is FALSE. Lotion D is more costlier because it has a greater slope than C.❌
d. Statement D is TRUE because for any amount on the x-axis, the cost of lotion D is always greater than that of lotion C.✅
