Answer:
32
Step-by-step explanation:
Calculation for how much birdseed does she have left over
First step
(3*8*6*12) - 4-2*30
Second step
=[24+6*(10+2)] - 4-60
Third step
Let remove the bracket of (10+2)
=[24+6*10+6*2] - 4-60
Fourth step
=(24+60+12) - 4-60
Fifth step
=(84+12)-4-60
Sixth step
=96-4-60
Seventh step
=92-60
=32
Therefore the amount of birdseed that she have left over will be 32
Answer:
7
Step-by-step explanation:
get the x on the same side.
subtract 2x from both sides
30=3x+9
then get the variables on one side by themselves. subtract 9 from both sides.
21=3x
now divide by 3 on both sides.
there's your answer.
The value of a will be 0.125. Then the value of a is positive then the parabola will be upward.
<h3>What is the parabola?</h3>
It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.
A parabola opening up or down has vertex (0,-4) and passes through (-12,14).
The equation of the parabola is given as
y = a(x - h)² + k
where (h, k) is the vertex of the parabola.
(h, k) = (0, -4)
Then the equation of the parabola will be
y = a(x)² - 4
The parabola is passing through (-12, 14). Then the value of a will be
14 = a(-12)² - 4
14 = 144a - 4
144a = 18
a = 1/8
a = 0.125
Then the equation of the parabola will be
y = 0.125x² - 4
If the value of a is positive then the parabola will be upward.
