Daily SAT 8/13/2022 (Math No-Calculator)
This question is worded in a slightly weird way, but if you understand what the question is asking for, it can be solved in about 5 seconds. When the question says how many solutions does the equation have, it really means how many zeros does the equation have, or in other words, what x-values make…

To find an equation that doesn’t have a solution, we must show that said equation can represent something that isn’t true, so lets go through each option and determine if it has a solution or not. For choice A, we can combine the right side into 6x and we get 6x = 3x, which we…

To answer this question very quickly, we must know about what is called the discriminant. The discriminant is the part of the quadratic equation that is under the square root symbol, b^2-4ac. Using the discriminant, we can find out how many solutions, or zeros, there are for a function. If the discriminant is positive, there…

What is given to us in the question is the biggest key to the puzzle here. The question says that MP = PR, meaning that the large triangle in the middle is an isosceles triangle, which means that angles PMR and PRM are going to be equal. Since angle MPQ is equal to 180 degrees…

To solve any question like this, we must attempt to isolate the x on one side of the equation. To begin, add 2 to both sides to get 2x/3 = x/3 + 3. From there, we can multiply both sides by 3 to get rid of the denominators. When we do this, we will be…

It is important to know the vertex form of a quadratic equation to answer this question. The form is y=a(x-h)^2 +k. In this equation, the variable h corresponds to the x-coordinate of the vertex of the graph and k corresponds to the y-coordinate of the vertex of the graph. So, in this case, the vertex…

Although the square root in the answer may seem intimidating, this question is easier than it seems. The main thing to know to solve this problem is the quadratic equation (used to factor and find values of x that will set the function equal to 0), which is shown below. A, b, and c correspond…

Looking at the function of this graph, the +2 inside of the parentheses means that there is a horizontal translation of 2 to the left for this graph. This is because the base function is f(x)=(x-h)+k, and since h (which represents the horizontal translation) is negative in the parent function, and 2 is positive in…

Since we are given the radius of the circle, we can immediately calculate the circumference of this circle using the equation 2πr (2π(4) = 8π). Now that we know the circumference (C=8π), you can give the circumference a common denominator with arc AB (5). We can multiply 8π by 5/5 to get 40π/5. We can…

To begin solving this equation, subtract 4 from both sides to end with |2x + 6| = 4 (with absolute value questions, always isolate the number or function on one side). Now, split this equation into two equations: 2x+6=4 and 2x+6=-4 (make the non-absolute value side of the equation both negative and positive), and solve…
