Answer
7.5 pounds
Step-by-step explanation:
Since adding x grams of salt will bring th percentage of the salt to 25
Hence. 10% of the 50 gram gives. 5 gram initial salt before it is added.
5+ x/ 50 * 100= 25/
5+x /50 = 0.25
5+x = 12.5
X= 12.5- 5
X= 7.5pounds
Answer:
Option B
Step-by-step explanation:
Given equation is
The original graph would be
From this transformations done are
a) horizontal shift of 5 units to the left
b) shrink vertical by scale factor 1/5
c) vertical shift of 2 units up
Hence option A is not right
Option B is right.
Similarly C and D are not right.
Step-by-step explanation:
option C
Answer:
I think this question needs more information.
Step-by-step explanation:
to figure out 110% of the students who walk, we need to know how many students walked to school.
All answer choices show the boundary line going through (0,-2) and (2,2). This is because y = 2x-2 goes through these two points. We make the boundary line a dashed line to indicate that solution points are not found on the boundary (because there is no "or equal to" portion in the inequality sign).
The shading is below the boundary line because of the "less than" sign. Any solution point (x,y) will have its y coordinate smaller than the y coordinate of points on the boundary line. So if (a,b) is on the boundary, then (a,c) is a solution where c < b.
In summary, the graph has a dashed boundary line and the shading is below the boundary
