Answer:
100 m3
Step-by-step explanation:
2*5*10 = 10*10 *100
Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 3y + 2x = 1 into this form
Subtract 2x from both sides
3y = - 2x + 1 ( divide all terms by 3 )
y = - 
x + 
← in slope- intercept form
with slope m = - → A
Answer:
10
Step-by-step explanation:
isolate y by adding 5 to each side. Now you have y=x+10. 10 is the c value, which is the y-intercept
Answer:
downwards
Step-by-step explanation:
the equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
• if a > 0 then parabola opens upwards
• if a < 0 then parabola opens downwards
for
f(x) = - 4(x - 3)² + 9 with a = - 4 < 0 , then
the parabola opens downwards
