The ratios are equivalent because 30 * 4 is 120 and 12 * 4 is 48
Answer:
Step-by-step explanation:
2x² + 6x - 5 = 0
D = 36 + 40 = 76 = (2√19)²
= ( - 6 - 2√19) / 4 = <em>( - 3 - √19) / 2</em>
= <em>( - 3 + √19) / 2</em>
Answer:
Yes
Step-by-step explanation:
This relation is a function. Functions must have unique x-values for every y-value, this relation meets those requirements. Also, since this is a graph you can use the vertical line test. To pass the vertical line test you must be able to draw a vertical line on the graph and have it intersect with the function in no more than one place.
Answer:
h(-4) = -4/3 = -1 1/3
h(2) = -2
h(5) = - 13/3 = -4 1/3
Step-by-step explanation:
h (-4) = -1/3 *16 + 4 = -16/3 + 12/3= -4/3 = -1 1/3
h(2) =2
h(5) = -1/3 *25 +4 = -25/3 +12/3= -13/3 = -4 1/3
A "True Proportion" is an equation which states that two ratios are equal.
