By working backwards,
<span>you get 76 as your answer because you have to remove the rightmost digit, right? so the three-digit number is </span>
<span>76x </span>
<span>(x stands for the rightmost digit, because we don't know what the rightmost digit is) </span>
<span>we are told we have to add six to the three digit number to get 76x, so we have to subtract 6 from 76x: </span>
<span>76x - 6 = ??? </span>
<span>since we assume that the original two-digit number is NOT 76, and any number from 760 to 765 inclusive minus 6 is logically in the 750-range, we can conclude that the original two-digit number is 75. </span>

Answer:
y = [-½]x + [-5]
Step-by-step explanation:
Equation describing how x and y are related can be written in slope-intercept form, y = mx + b.
m = slope = ∆y/∆x
Using two pairs of values from the table, (-2, -4) and (0, -5),
Slope (m) = (-5 - (-4))/(0 - (-2)) = -1/2
m = -½
b = y-intercept = the value of y when x is 0 = -5
b = -5
✔️To write the equation, substitute m = -½ and b = -5 into y = mx + b
Thus:
y = [-½]x + [-5]
Answer:
<em>2.399</em>
Step-by-step explanation:
Given the trigonometry expression:
tan(sin^-1((-12/13))
We are to find the exact value
tan(sin^-1((-12/13)) = tan(sin^-1((-0.9231))
tan(sin^-1((-12/13)) = tan(-67.38)
Also note that tan(-theta) = -tan theta
tan(-theta) = -tan67.38
tan(-67.38) = -2.399
<em>The exact value is 2.399</em>
Answer:
w=-2
Step-by-step explanation:
9(w-4)-7w=5(3w-2)
9w-36-7w=15w-10
9w-7w-15w=-10+36
-13w=26
w=-2
