Just the first one, r is 4x+2, and h is 5x+4, plug them into the formula pls
Answer:
(2,1)
Step-by-step explanation:
3x+y = 7
-2x +y = -3
Solve the second equation for y by adding 2x to each side
-2x+2x +y = -3+2x
y = -3 +2x
Substitute into the first equation
3x+ (-3+2x) = 7
Combine like terms
5x -3 = 7
Add 3 to each side
5x-3+3 = 7+3
5x = 10
Divide by 5
5x/5 = 10/5
x=2
Now we need to solve for y
y = -3 +2x
y = -3 +2(2)
y = -3+4
y =1
Answer:
the answer should be B
Step-by-step explanation:
the first part is basically finding the difference between the terms, as we know that d=T2-T1
so by comparing the T2-T1 and T3-T2 we can find the difference with the two variables h and k
afterwards do the same with T4-T3 and T3-T2, comparing them and you will get another equation
now that you have two equations, you can do simultaneous equation to get the answers
hope i helped :D
Answer:
B
Step-by-step explanation:
The y-int. is -5 like the equation and the slope is positive
Answer: (d)
Step-by-step explanation:
Given
XYZA is a rhombus and side XY is 8 units
We know, In a rhombus
- All sides are equals
- Diagonals bisect each other perpendicularly
Using the above property, we can write

Thus, option (d) is correct.
