Okay so first
you have the constant (4) to the other side of the equation and change the sign.
since you have x=7+mn-4 now you gave to collect like terms (7-4).
leaving the equation x=3+mn
to finish the equation you have to rewrite the equation to parametric form. x=3+mn, m to R (all real numbers), n to R (all real numbers) hope it helped
I think a. 8x+7x=90
That's how i usually do these type of questions.
~
x= 6
8x=48
7x=42
Answer:
See below in bold.
Step-by-step explanation:
A. (x + 7)^2 + (y - 7)^2 = 10.
This is the equation of a circle.
It is NOT a function
One to many correspondence.
B. y = x^2 + 2x - 3
This is a parabola which opens upwards.
It is a function.
For 2 values of x ( except at the vertex) there is one value of y so it is
many to one correspondence.
Answer:
False -1
Step-by-step explanation:it is both less than 7 and 2 therefore that statement is false
