Answer:
Step-by-step explanation:
use the formula y=mx+b. the first number in the parenthesis is -3 so that is x. 3 is y and the slope is m
so it is 3=4(-3)+b
Answer: The dimensions of the rectangle are 6ft and 16ft.
Step-by-step explanation:
Let the width of the rectangle be y
Let the length of the rectangle be y+10
Area= 96ft
Since area of a rectangle is length multiplied by width
y(y+10) = 96
y^2 +10y =96
y^2 +10y -96= 0
Solving algebraically,
y^2 +16y - 6y - 96= 0
y(y+16) - 6(y+16)= 0
(y-6)(y+16)= 0
y-6= 0
y =6ft
Recall that the width was denoted as y. That means the width is 6ft.
Since length is y+10= 6+10 = 16ft
Length is 16ft, width is 6ft.
Answer:
The correct answer is 3. -88
Step-by-step explanation:
24 / 3 + 24 x -4
24 x -4 = -96
24 / 3 = 8
8 + -96 = -88
Answer:
30
Step-by-step explanation:
25£ : 650 rubles
x£ : 780 rubles
25/x = 650/780
(cross multiply)
650x = 25×750
650x = 18 750
divide 18 750 by 650
which is = 30
thus x = 30
