2/7 = x/10
cross multiply:
10 * 2 = 20
7 * x = 7x
7x = 20
x = 2.857
You could re-write this to make it into an equation, you want to isolate the y, for a slope-intercept form. So you +8 to the other side; so it would be 7x+8=14y, then divide it by 14. And your equation would be y=4/7+x/2.
Answer:
b) three terms
c) -1
d) 7
e) 4
Step-by-step explanation:
put the expression in decreasing exponent order with the constant at the end
-x⁴ - 2x + 7
With this format it is easy to find the leading coefficient which is the coefficient of the term with the highest exponent; in this case you only see a negative sign but every variable, if no other coefficient is present, has an invisible '1'
