Answer:
The perimeter is 44. Because we know the midpoints and distance between the sides of XR is half the side and YS is half the other side, those sides are 10 and 14. QS is a full side already so it is just 20. 20+14+10=44 for the perimeter.
Number 2 makes no sense, you've omitted something needed there.

Step-by-step explanation:
Given the 2 equations
y = x² + 2x + 7 → (1)
y - 7 = x → (2)
Rearrange (2) expressing y in terms of x by adding 7 to both sides
y = x + 7 → (3)
Substitute y = x + 7 into (1)
x + 7 = x² + 2x + 7 ( subtract x + 7 from both sides )
0 = x² + x ← factor out x from each term
0 = x(x + 1)
Equate each factor to zero and solve for x
x = 0
x + 1 = 0 ⇒ x = - 1
Substitute these values into (3) for corresponding values of y
x = 0 → y = 0 + 7 = 7
x = - 1 → y = - 1 + 7 = 6
The solutions are
(- 1, 6 ) and (0, 7 )
Answer:abudul should have divided by 4 ,not 6
Step-by-step explanation:
- 4(1/2)x - (3/7) = (1/4)
- 4(1/2)x = (1/4) + (3/7)
- (9/2)x = (7+12)/28
-(9/2)x = 19/28
x = (19/28) * 2 / 9
x = (19/14) / 9
x = 19 / (14*9)
x = 19 / 126
Answer:
well, okay. its basically what you wrote. assuming there was missing information.
let's dive right into it.
we'll assume that the problem asks for integers, whole numbers.
if x would be 0,
we would get 9 numbers out, 0, -1, -2, -3, -4, -5, -6, -7 and -8
if x would one, the range would be from 7 to -8, giving us 16 numbers
if x would be 2, the range would be from 14 to -8, giving us 23 numbers (7 more each time we increasex by one)
so the answer isn't a fixed value, but a function.
7x+9
the plus nine is true when x=0 and is still relevant for every other scenario
