1000 divided by 5 equals 200. You can think of it as breaking down the problem into easier parts, using basic division facts to find the answer.
Yes, x-intercepts remain unchanged when a graph is reflected over the x-axis. Since x-intercepts lie on the x-axis, their y-value is always zero, making them invariant under reflection.
The most important point in a quadratic function is the vertex. It serves as the turning point where the graph switches from decreasing to increasing (or vice versa).
To calculate the volume of a triangular prism, use the formula V = Base Area × Height. For surface area, add the areas of all faces, including the two triangular bases and three rectangular sides.
To solve sticker word problems, start by identifying how many stickers are given away or used. Use subtraction for these actions to find out how many stickers remain.
When reflecting a point over the x-axis, the x-coordinate remains the same while the y-coordinate changes sign. For example, the point (2, 25) reflects to (2, -25). Reflecting over the y-axis changes the sign of the x-coordinate instead.
To multiply binomials, use the distributive property by multiplying each term in the first binomial by each term in the second. For example, when multiplying (2x - 5)(x + 12), you get 2x² + 24x - 5x - 60.

Here are 5 math review questions for 4th graders: 1) What is 23 + 45? 2) Subtract 67 from 100. 3) What is 5 x 6? 4) Divide 36 by 4. 5) What is the area of a rectangle with a length of 8 and width of 3?
To solve the equation 15 = (x + 2)/-3, multiply both sides by -3 to isolate x. This gives x = -47 after performing the necessary arithmetic.
To solve the equation F - 1 - 2F = -2 × 3 + F, first simplify both sides and combine like terms. You will find that F = 2.5.
To find f(-3) for the function f(x) = x² + 10x + 6, substitute -3 for x. This gives you f(-3) = (-3)² + 10(-3) + 6 = -15.
To write a quadratic equation in vertex form, use the format y = a(x - h)² + k. Complete the square if necessary, or identify perfect square trinomials directly.
To find the axis of symmetry for the parabola given by the equation y = x² + 3x, use the formula x = -b/(2a). Here, a = 1 and b = 3, resulting in an axis of symmetry at x = -3/2.
To evaluate a quadratic function like f(x) = x² - 5x + 7, substitute the value of x into the formula. For f(-4), the answer is 43, confirming your choice was correct!
To solve the equation $$\frac{2f}{5} - \frac{8}{5} + 2f = 8$$, first combine like terms and isolate the variable. The solution is $$f = 4$$.
To find the average rate of change for functions like y = 4^x and y = 4x^2, calculate the values at the given points and use the formula for slope. Both functions will yield the same average rate of change on the interval [0, 1].
To solve inequalities like x + 2 ≥ 6 and 3x ≥ 6, isolate x in each. The solution is where both inequalities hold true, resulting in x ≥ 4.
