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.

Jun 30, 2015 · 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.

Mar 21, 2021 · The product of the fractions is 12/35, or 2/5 x 6/7 as a fraction is equal to 12/35. Given that we need to convert 2/5 x 6/7 in a fraction. To multiply fractions, you** simply multiply** the numerators (top numbers) together and the denominators (bottom numbers) together. In this case, you have: (2/5) x (6/7)

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 ...

Feb 3, 2025 · The frequency of ultraviolet (UV) light ranges from about 7.5 x 10^14 Hz to 3 x 10^16 Hz, corresponding to wavelengths of approximately 10 nm to 400 nm. UV light is divided into different ...

When we multiplied both sides of the equation by the LCD, (x+7)(x-7), we multiplied by something that might be zero. In fact, if x = -7 like our solution says, we can see that the LCD was zero. And since a solution found by multiplying both sides by a zero in invalid. We must reject this solution!

(-7,4) y+5x =-11 The slope-intercept form of a line is: y = m*x + b where m is the slope of the line and b is the value of y where the line crosses the y axis (that is when x=0). If we take the line y + 5*x = -11 and rewrite it in slope-intercept form we have: y = -5x - 11 In this form we can see the slope of the line is -5.

The amount of numbers that are multiples of 5 in this product is 7 (one multiple of 5 in each range 1 - 9; 11 - 19; 21 - 29; 31 - 39; 41 - 49; 51 - 59 and 61 - 69). When such a multiple of 5 is married with the factor "2" from 1024, it produces one zero at the end. In this way, we get 7 zeroes at all at the end, for now.

Mar 11, 2025 · Abraham lived to 175 (5 X 5 X 7) Isaac lived to 180 (6 X 6 X 5) Jacob lived to 147 (7 X 7 X 3) An analysis of these ages shows: Each lifespan involves a perfect square (5, 6, then 7 in a numeric ...
