Answer:
x=-4/k
Step-by-step explanation:
Let's solve for x.
kx+8=4
Step 1: Add -8 to both sides.
kx+8+−8=4+−8
kx=−4
Step 2: Divide both sides by k.
kx
k
=
−4
k
x=
−4
k
Answer:
x=
−4
k
Step-by-step explanation:
1- 3x-3= 6 (x-10) organise the terms
2- 3x-3= 6x- 60 calculate (always brackets first)
2- 3x-6x= 3-60 Put the like terms on the correct side. Always put terms with x on the left.
3- -3x= -57 Calculate sums
4- x= -57÷-3=19 Divide
5- x= 19
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
----> inequality A
The solution of the inequality A is the shaded area below the dashed line
The slope of the dashed line A is positive m=2
The y-intercept of the dashed line A is (0,-5)
The x-intercept of the dashed line A is (2.5,0)
----> inequality B
The solution of the inequality B is the shaded area above the dashed line
The slope of the dashed line B is negative m=-3
The y-intercept of the dashed line B is (0,1)
The x-intercept of the dashed line B is (1/3,0)
The solution of the system of inequalities is the shaded area between the two dashed lines
using a graphing tool
The graph in the attached figure
9 times 4 is $36 which is the price of the belt
$36 + $9 = 45
$45 + $ 10 = 55 so
<u>Keith had $55 dollars before he bought the shirt and the belt
