Answer: A
Step-by-step explanation:
The simplest solution:
y - intercept of the function on the graph is (0; 6).
Only function f(x) = (4x^2 - 7x - 2)(2x - 3) has that y-intercept
f(0) = (4 · 0² - 7 · 0 - 2)(2 · 0 - 3) = (-2)(-3) = 6
Other functions have y - intercept equal (0; -6).
f(0) = (0 ... - 2)(0 + 3) = (-2)(3) = -6 or f(0) = (0 ... + 2)(0 - 3) = (2)(-3) = -6
60+60 - hour heads up
80x-each hour travels 80miles
And both have a variable (x) that represent the number of hours
Equation:
60+60x=80x
Combine terms:
60=20x
Divide both sides by 20:
X=3
Soooo that means at 3:00pm two trains will be at the same distance from Chicago which is 240 miles
Hope this helps
Answer:
C) The triangles are not similar.
Step-by-step explanation:
These triangles are not similar. Similar triangles are triangles with the same angle measurements and proportionate side measures. However, these sides are not proportionate and therefore the triangles are not similar. You can tell the sides are not proportionate because on one triangle the two given sides (which are corresponding with the other two given sides) are congruent but the other triangle has no congruent sides. This also means that the smaller triangle is isosceles while the larger one is scalene, and different triangle types cannot be similar.
