2023年2月24日 · Matrix B, when multiplied with matrix A (5 x 3), must be sized 3 x 7 in order to yield a product of 5 x 7. If the product BC results in a 5 x 4 matrix, then matrix C must have 4 rows, confirming that B has 3 rows. Therefore, B is a 3 x 7 matrix.

2016年5月10日 · Understanding the Function: The function f (x) = 5 x − 7 consists of an exponential function 5 x and a constant − 7. Exponential functions are defined for all real numbers. This means you can plug in any real number for x. Exponential Function Behavior: The graph of 5 x will never touch or cross the x-axis, and it will always be positive ...

2017年5月8日 · 25 - x^2. Now we need to set it equal to the other side and solve for 0. 25 - x^2 = 7 ----> subtract 7 from both sides. 18 - x^2 = 0 -----> now readjust the order-x^2 + 18 = 0. So, once we've reached here, the a value is always the coefficient of the x^2 term (-1), b is the value of the coefficient of the x term (0) and c is the constant (18).

2017年2月13日 · Start with the expression: 5 (x + 7). Distribute 5 to both x and 7: Multiply 5 by x: 5 × x = 5 x; Multiply 5 by 7: 5 × 7 = 35; Combine the results from both multiplications: 5 (x + 7) = 5 x + 35. Therefore, the equivalent expression is 5 x + 35. Out of the answer choices provided: A. 5 x + 12 B. 5 x + 35 C. 5 x + 7 D. 40 x. The correct answer ...

First Option: y = 5 (x − 6) 2 + 5. This is in vertex form, where the vertex is at (6, 5). Since the coefficient of the squared term is positive, this parabola opens upwards. Second Option: y = 5 (x − 7) (x − 5) This is in factored form, which indicates its roots are at x = 7 and x = 5. This graph also opens upwards as the leading ...

2022年5月19日 · 5 x 7 = 35. So, you have 35/20. Now, both the numerator and the denominator have common factors that can be divided out to simplify the fraction. The greatest common divisor of 35 and 20 is 5. So, if you divide both the numerator and the denominator by 5, you get: 35 ÷ 5 = 7. 20 ÷ 5 = 4. Thus, the simplest form of the fraction is 7/4.

2015年6月30日 · To simplify (x+5)(x-7), multiply the first, outer, inner, and last terms and combine like terms to get x^2 - 2x - 35. To simplify the expression (x+5)(x-7), you need to apply the distributive property, also known as the FOIL method, which stands for First, Outer, Inner, Last.

2024年2月24日 · x=ln(7) / ln(4) +2. x=ln(7) / ln(4) +2 / 5. x=ln(7)+2ln(4) / 5ln(4) This expression represents the exact solution for x in terms of natural logarithms. If you want a numerical approximation, you can substitute the values of ln(7) and ln(4) and evaluate the expression. This would give you an approximate value for x. COMPLETE QUESTION: Solve each ...

2019年2月27日 · To find an expression equivalent to the expression 5 (x + 7), we can use the distributive property, which says to multiply each term inside the parentheses by the term outside. Step 1: Write down the expression. 5 (x + 7) Step 2: Apply the distributive property. This means we multiply 5 by both x and 7: 5 ⋅ x + 5 ⋅ 7. Step 3: Perform the ...

2020年10月2日 · To find the value of x given the options, we need to look at each provided value for x: x = 7; x = 5; x = 16; x = 34; It seems like the question is presenting multiple possible values for the variable x, but it is important to note that each instance presents a different potential definition of x without any context or relation between them.
