If a = 24 and b = -6 then 24--6 = 30 because --6 = +6
5
Only when a and b have the same sign (or when a or b equals 0). Here are some examples: |2+4|=|2|+|4|--> |6|=|6|--> 6=6 TRUE |(-1)+(-3)|=|(-1)|+|(-3)|--> |(-4)|=1+3--> 4=4 TRUE |3+(-6)|=|3|+|(-6)|--> |(-3)|=3+6--> 3=9 FALSE
For a value to be a solution to an equation, when you substitute the value for the variable, the equation becomes true. 4+B=6 B is the variable. 2 is the solution Substitute 2 for B 4+2=6 The equation is true.
Y = mx + b such as y = 3x + 5 the y-intercept (b) = 5
30
30
If a = 24 and b = 6, then a - b = 24 - 6 = 18
If a = 26 and b = 6 then a - b = 20.
B/5 = 6 means that 6 x 5 = B 6 x 5 = 30 Therefore, B = 30
5........is this really a question? when b=5, then b=5
If a + b = 6, what is the value of 3a + 3b?
(b - 5) + 6 Also, (b + 1) .
If a = 24 and b = -6 then 24--6 = 30 because --6 = +6
If b = 5 then 15-10 = 5
6
Multiply the expression (fraction) by (6 + √5)/(6 + √5) (which is 1 and will not change its value).3/(6 - √5) x (6 + √5)/(6 + √5)= 3(6 + √5)/(6 - √5)(6 + √5)= 3(6 + √5)/(36-5) = 3(6 + √5)/31= 3/31(6 + √5)Remember:(a + b)(a - b) = a2 - ab + ab - b2= a2 - b2So if either a or b contains a square root, a2 and b2 will not, and so a2 - b2 will not!
