Go up the y axis 3 points and place a dot there. This is the y intercept
Then, from that point, go down 1 unit and over 2 units
It should look like a line going downwards with a y intercept of 3
Hope this helps!
Answer:
f(x) = (4x - 1)(2x + 1)
The zeros of the function are 
and 
.
Step-by-step explanation:
The given quadratic expression is 8x² - 2x - 3.
Now, the factorization of this quadratic expression gives:
f(x) = 8x² - 2x - 3
⇒ f(x) = 8x² - 6x + 4x - 3
⇒ f(x) = 2x(4x - 3) + 1(4x - 3)
⇒ f(x) = (4x - 1)(2x + 1)
Hence, the zeros of the function are and . (Answer)
Answer:
Amount of vinegar. 100% : 20 milliliters
Amount of Italian dressing: 140 milliliters
Step-by-step explanation:
Let's call A the amount of vinegar. 100%
Let's call B the amount of Italian dressing . 12% vinegar
The resulting mixture should have 23% vinegar, and 160 milliliters.
Then we know that the total amount of mixture will be:
Then the total amount of pure antifreeze in the mixture will be:
Then we have two equations and two unknowns so we solve the system of equations. Multiply the first equation by -1 and add it to the second equation: We substitute the value of B into one of the two equations and solve for A.
The magnitude is what it equals
