X+ 3y = 1 -----(first equation)
-2x+7 = -23 ---(second equation)
-2x = -23-7
x = 30/2
x = 15
Now, Substitute the value of x in first equation,
15 + 3y = 1
3y = 1 - 15
y = -14/3
In short, Final Answers are: x = 15 & y = -14/3
Hope this helps!
Answer:
-2.45
Step-by-step explanation:
You are asked to EVALUATE 8.722÷(−3.56). Here you are dividing a positive number by a negative one, and so you expect that the result (quotient) will be negative.
Thus, 8.722÷(−3.56) becomes -8.722÷(3.56) = -2.45
Answer:
Area of the Rectangle is (length×breadth)
Third option is the right answer.
Answer:
The numbers are 42 and 49
Step-by-step explanation:
Let's make it into a simple equation. Make the ratios into a single variable like this: 6x+7x=91. If you simplify it more you would get 13x=91. From here divide both sides by 13. This will result with x being 7. But the problem wants you to find 6x and 7x. If you multiply 7 with 6 you would have an answer of 42. If you multiply 7 with 7 you get 49. If you want to check add 42 and 49. If you get 91, this means that the answer is correct
P(1, 2), Q(3, 4)
we find the slope dividing the y over the x, that is:
m = (4 - 2)/(3 - 1) = 2/2
m = 1
and then use the line equation for a point and slope:
y - y1 = m(x - x1)
where (x1, y1) is a point through which the line passes, we use P(1,2):
y - 2 = 2(x - 1)
y - 2 = 2x - 2
y = 2x
therefore the slope is 2 and the y-axis intercept is 0
