Answer:
78 ml of 7% vinegar and 312 ml of 12% vinegar.
Step-by-step explanation:
Let x represent ml of 7% vinegar brand and y represent ml of 12% vinegar brand.
We have been given that chef wants to make 390 milliliters of the dressing. We can represent this information in an equation as:
We are also told that 1st brand 7% vinegar, so amount of vinegar in x ml would be .
The second brand contains 12 vinegar, so amount of vinegar in y ml would be .
We are also told that the chef wants to make 390 milliliters of a dressing that is 11% vinegar. We can represent this information in an equation as:
Upon substituting equation (1) in equation (2), we will get:
Therefore, the chef should use 78 ml of the brand that contains 7% vinegar.
Upon substituting in equation (1), we will get:
Therefore, the chef should use 312 ml of the brand that contains 12% vinegar.
Hi there!
h(x) = 5x + 11
To find h(7) - 3, we can substitute 7 for x and subtract 3:
h(7) = 5(7) + 11 - 3
Simplify:
h(7) = 35 + 11 - 3
h(7) = 43
Point symmetry is a 180 degree rotation around the origin.
It maps (x,y) to (-x,-y).
So (2,6) and (-1,2) map to
(-2,-6) and (1,-2), third choice
