Answer:
3/4
Step-by-step explanation:
5 3/8 - 4 5/8
We need to borrow from the whole number
5 becomes 4 and the one becomes 8/8
4 + 8/8+ 3/8 - 4 5/8
4 11/8 - 4 5/8
Subtract the fractions
6/8
Simplify the fractions
3/4
Answer:
False, False, A. 180
Step-by-step explanation:
A flat line is 180 degrees. A right isosceles triangle has one right angle. None of the sides on a scalene triangle are the same.
Answer:
(x+7)(x-7)
The factors are -7 and 7
Step-by-step explanation:
Given the function x²-49, to find the factors, we will factorise the expressed using the different of two square.
If a and b are two numbers, then based on difference of two square;
a²-b² = (a+b)(a-b)
Applying this to the function in question
x²-49
= x²-7²
= (x+7)(x-7)
The factors can be gotten by equating the function to zero according to factor theorem.
(x+7)(x-7) = 0
x+7 = 0 and x-7 = 0
x = -7 and 7
Answer:
So the slope in this case is m = -2. Using point (0, 7) and m =-2 with point-slope we have y - 7 = -2(x-0) => y = -2x +7. Then we realize (0,7) actually is the y-intercept. We could have gone directly to y = -2x + 7. If we use (3,1) and m = -2 we get y-1=-2(x-3) => y -1 = -2x+6 => y = -2x+7. Another way to find y-intercept is to use y = mx +b directly. If we use the point (3,1) that means when x=3, y = 1. So 1=-2(3) + b => 1=-6+b => b = 7. So, y = -2x+7. Same result in all cases. I like to use point-slope. Others prefer to use y = mx+b, substituting for x, y, and m to solve for b.
Step-by-step explanation:
The Distributive Property is an algebra property which is used to multiply a single term and two or more terms inside a set of parentheses.so the resulting expression when you of apply the distributive property to 14(−3n+32)= (14) (-3n) + (14) (32)= -42n + 448
