Answer: X= -9
Step-by-step explanation: solve for x by simplifying both sides of the equation then isolating the variable
Answer:
k = -3/4
Step-by-step explanation:
The lines will be parallel if their slopes are equal. To find the slope of each line, write its equation in slope-intercept form (y = mx + b). In other words, solve each equation for y and look at the coefficient of x.
2x + 3y = 4k
3y = -2x + 4k
y = (-2/3)x + 4k/3
The slope of the first line is -2/3.
x - 2ky = 7
-2ky = -x + 7
y = [1/(2k)]x - 7/(2k)
The slope of the second line is 1/(2k).
If the slopes are equal, then
1/(2k) = -2/3
Multiply by 2k.
1 = (-2/3)(2k) = (-4/3)k
1 = (-4/3)k
k = -3/4
Hello.
Here's our explanation: First, you had to multiply line them up. , then 3*3=9. Bring down the zero, then multiply 2*2=4. And 3*2=6, which gives us equal to 640. Finally, add it up, 96+640=736. 736 is the final answer.
Hope this helps!
Thanks!
Have a great day!
The correct answer is B :)
Answer:the area increases by 6square unit
Step-by-step explanation:
First area. 1/2b×h
1/2×4×3=6squre unit
Second area..1/2×4(2×3)
1/2×4×6=12 square units...
Difference is 6 square units
