24:05 couldn't u use -b/2a for this one to set up an equation? you know 3.5 = -b/2a ,so solving for b you'd get b = -7a. so a+b would be a-7a or -6a. So, the only answer choice that works here is D
Yes, that also works. If you know that the x-coordinate of the vertex can be found by getting the mid-point of the 2 x-intercepts that is another good way to solve!
Sorry! Mentioned it in the original videos series (October SAT Predictions) that I transcribed answer choice D incorrectly...so in the way I transcribed it D could be correct.
Hey I am one of your biggest fans. I wrote the October sat. There was a question about four consecutive odd numbers and I know you have heard about it, it was a student response question. Please on your opinion is it meant to be an experimental question because me and my friends have never seen a math question like that before
There is no way to know if it is experimental. I haven't seen any questions like that in many years on the SAT, so it is possible it is the experimental one and maybe they will use it on future tests depending on student performance on this one. Let me know what you score when results come out! =)
@@EziokwuMgbeokwere It was manageable lol I managed to get it just come up with an equation, odd numbers differ from each other by two, create something like, x, for the first odd number, x+2, for the second odd number, x+4, the third odd number, x+6, the fourth odd number
Please for the last question do you mean the exact wording of the question because I get the same format of question but not the exact numbers. Because you making afraid

I can confirm the questions #1,2,,5,6 were exactly in my test. I could not quite recall the rest of them. (and I am not from the us, so I took the international one)
Hello, there was a question which is a bit unclear. This is the question: "During the decades-long movement to codify the rights of Latinos in the US, certain events were pivotal: the founding of veteran rights group the American GI Forum in _____ Mendez v. Westminster court decision in 1946, which affirmed the rights of Latino students, is another such event." The answer choices are: A) 1948, for one. The B) 1948. For one, the C) 1948, for one, the D) 1948 for one, the
I believe it would be A. Put "For one" at the beginning right after the colon. It would read ":for one, the founding of veteran rights group the American GI Forum in 1948. It definitely is not c as "Mendez v. Westminster court decision in 1946, which affirmed the rights of Latino students, is another such event." is an independent clause and c creates a comma splice.
Please would you mind answering this question today? The function f is defined by f(x)= a(3.7^x+ 3.7^b), where a and b are integer constants. The functions g and b are equivalent to function f, where k and m are constants. Which of the following equations displays the y-coordinate of the y-intercept of the graph of in the xy-plane as a constant or coefficient? I. g(x)=a(3.7^x+k) II. h(x)=a(3.7)^x +m A) I only B) II only C) I and II D) Neither I nor II
just finished the video after pausing and doing every problem I could on my own, thanks for this, it really helps me cuz I left studying so late since I was working on my college apps xd
hi so for the question at 56:54 why isnt II correct becuase the equation for ax+ab would have to equal to 9x+9b and if u plug in 5 the slope would have to be different right?
Confused on the problem that details: Circle perimeter of equilateral triangle = 642 cm and is inscribed in a circle. I'm confused when you split up the triangle into two 30-60-90 triangles and you draw the lengths and state x is 107 and xsqrt3 is 107sqrt3 but you then solve for xsqrt3 when you already stated it was 107sqrt3. Slightly confused there, would love if you could explain. Great advice though
I won't have time for this exam. I am swamped! However, my Reading from predictions for August are relevant to this exam =) : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-9stuR0Ma8iA.html
3/5 questions are similar to what can be found on collegeboard....the unique ones are the right triangular prism and the equilateral inscribed in the circle (haven't seen them on collegeboard, but they are similar questions from paper-based SAT). =)
