Answer:
2.3
Step-by-step explanation:
Use Pythagorean theorem:
9i-j = sqrt (9^2 - 1^2) = sqrt(81-1) = sqrt80
now divide both terms in V by that:
u = 9/sqrt(80)i - 1/sqrt(80)j

Answer:
9 is your answer for x.
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Do the opposite of PEMDAS.
PEMDAS is the order of operations, & =
Parenthesis
Exponent (& Roots)
Multiplication
Division
Addition
Subtraction
First, subtract 13 & 8x from both sides:
2x (-8x) + 13 (-13) = 8x (-8x) - 41 (-13)
2x - 8x = -41 - 13
Simplify. Combine like terms:
-6x = -54
Isolate the variable, x. Divide -6 from both sides:
(-6x)/-6 = (-54)/-6
x = (-54)/(-6)
x = 9
x = 9 is your answer.

That’s a very good question but i don’t know the answer however it may be animals
Answer:
Step-by-step explanation:
it is hard to know exactly by eye balling the graph I can't dissern the y intercept it might be 4.5 but it could be 4.33, but it looks for sure like the x intercept equals 6 but does it
the dots on the line are at (-2, -6) and (2, 3) so we can find the slope m
in the y = mx + b line equation b is the y intercept
m = Δy/Δx = (y1 - y2) / (x1 - x2)
= (-6 - -3) / (-2 - 2)
= -3 / -4
m = 3/4
y = 3x/4 + y intercept which i can't dissern (read directly from the
graph, but we believe y = 0 when x is six
0 = 3(6)/4 + y intercept
-18/4 = 18/4 -18/4 + y intercept
-9/2 = y intercept
-4.5 = y intercept
y = 3x/4 - 9/2 i think exact number means NO FRACTIONS but that is whole number so let me gaggle it What are exact numbers? Gaggle indicates exact numbers are integers example 3 ft in a yard 12 eggs in a dozen
y = 3x/4 - 9/2 multiple both sides by 4
4y = 3x - 36/2
4y = 3x - 18 <------------------ FINAL ANSWER
