We know that
the x-intercept is when y=0 and z=0
<span>-3x + 5y - 2z =60------------> -3x=60----------> x=-20
the point (-20,0,0)
</span>the y-intercept is when x=0 and z=0
-3x + 5y - 2z =60------------> 5y=60----------> y=12
the point (0,12,0)
the z-intercept is when y=0 and x=0
-3x + 5y - 2z =60------------> -2z=60----------> z=-30
the point (0,0,-30)
the answer is
(-20,0,0)
(0,12,0)
(0,0,-30)
So set up the equations
q-12=d
25q+10d=1105
plug in q-12 as d in the second equation:
25q+10q-120=1105, then simplify:
35q=1225
q=35
since there's 12 fewer dimes, we know that there's 23 dimes and 35 quarters.
Answer:
40 cups
Step-by-step explanation:
7 part nuts and 2 parts M&M makes up 1 trail mix
7 and 2 part = 9 parts in total
There are 180 cups in total, so each part would be:
180/9 = 20 cups = 1 part
Now, we know there are 2 parts M&Ms and there are 20 cups in a part, so:
M&Ms required = 2 * 20 = 40 cups
Answer:
y² = 36x
Step-by-step explanation:
Parabola opens right.
Thus equation is from; y² = 4ax
And focus is at (a, 0)
Since we are given focus at (9, 0),it implies that a = 9
Thus, equation of parabola is;
y² = 4 × 9 × x
y² = 36x
