2x - 3(x-1) = -1
2x -3x + 3 = -1
-1x + 3 = -1
-1x = -4
x = 4
y = 4 - 1
y = 3
You plug in number for number getting 194.8 which is equal to 2931
Answer:
2/2 = 1
Step-by-step explanation:
y2 - y1 4 - 2 2 Equals 1
x2 - x1 8 - 6 2
Below are the choices:
A. 80 mL of the 3.5% solution and 120 mL of the 6% solution
<span>B. 120 mL of the 3.5% solution and 80 mL of the 6% solution </span>
<span>C. 140 mL of the 3.5% solution and 60 mL of the 6% solution </span>
<span>D. 120 mL of the 3.5% solution and 80 mL of the 6% solution
</span>
Let fraction of 3.5% in final solution be p.
<span>p * 3.5 + (1 - p) * 6 = 4.5 </span>
<span>3.5p + 6 - 6p = 4.5 </span>
<span>2.5p = 1.5 </span>
<span>p = 3/5 </span>
<span>3/5 * 200 = 120 </span>
<span>Therefore the answer is B. 120 ml of 3.5% and 80 ml of 6%.</span>
Answer:
(11, 0)
Step-by-step explanation:
to find the y intercept, set y to 0.
60x + 55y = 660
60x + 55 * 0 = 660
60x = 660
60x/60 = 660/60
x = 11
y intercept is (11, 0)
