Let x equal a number
3x + 5 = 26
3x = 21
x = 7
the number is 7!
the only like-terms are on the right-hand-side, since the left-hand-side has only 1 term anyway.
Answer:
That is correct
Step-by-step explanation:
180° rotation about origin just means that you have to flip the pre-existing image across the x-axis
Good job!
You can first take out an x^2 from each number , 3x^6 - 39x^4 + 108x^2 = x^2 ( 3x^4 - 39x^2 + 108) Then just factor and solve for the zero's of the equation
Answer:
let c is a point between a and b we can find the coordinates of c by using mid-point formula
the coordinate x of c is equal to
x=(x1+x2)÷2
x=(3+27)÷2
x=30÷2
x=15
the coordinate y of c is equal to
y=(y1+y2)÷2
y=(2+30)÷2
y=32÷2
y=16
so the coordinates of c are (15,16)
