Answer:
7
Step-by-step explanation:
Move the -8 to the other side and use the rule change side change sign:
2x=6+8
2x=14
Move the 2 and convert the multiplication(as its 2×x ) into division:
x= 14÷2
x=7
Answer:
Their is a different question in the pic then the writing?
Answer:
(-5, -8)
Step-by-step explanation:
-3x+3y=-9
-3x+y=7
----------------
simplify -3x+3y=-9 into x-y=3
----------------------------------------
y=x-3
-3x+y=7
------------
-3x+(x-3)=7
-3x+x-3=7
-2x-3=7
-2x=7+3
-2x=10
x=10/-2=-5
y=-5-3=-8
x=-5, y=-8
The complete question in the attached figure
we have that
f(x)=x²-5x+6
and <span>g(x) has a vertex at (2,4) and the parabola opens downwards
using a graph tool
see the attached figure
</span><span> statements
a) </span><span>The y-intercept of function f is less than the y-intercept of function g
this is not correct, because the </span>y-intercept of function f is greater than the y-intercept of function g
b) <span>The minimum of function f is at (-5,6)
this is not correct, because the minimum of function f is at (2.5,-0.25)
c)</span><span>The y-intercept of function f is greater than the y-intercept of function g
this is correct
d) </span><span>The minimum of function g is at (2,4)
this is not correct because the maximum of function g is </span>(2,4)
the answer is the option
The y-intercept of function f is greater than the y-intercept of function g
Answer:
Because the demographic group is dictated by location of the college. In this case the students are all college bound and have like socio ecconomic backgrounds.
A true sampling would be a mixed demographic group. A sampling from several like areas: e.g. infront of the student store, infront of the regular store, infront if a food pantry, infront of ... or even better do a blind survey.
