Answer:
y-int = (0, -6)
Step-by-step explanation:
The y-intercept is the b-value of the equation of the line y = mx+b
To find the y-intercept plug in 0 for the x-value:
y=3(0) - 6
y= -6
-> x = 0, y = -6
For b), the answer is 3^2 / 2^7
you just have to multiply the exponent of 2 with 2 and add it with 3
for c), the answer is -(3)^3
notice that the negative sign is outside the parenthesis
for d), the answer is 1
you just multiply -n with 3 and all the exponents since they all have the same base
for e), the answer is 2a^2 b
just distribute the exponent 2 to all the bases and cancel out the things that can be cancelled or just subtract exponents of the same bases if the operation is division
for f), the answer is b^4 / 2b^4
focus first on the things inside the parenthesis, then take not of the -1 exponent after

Answer:
322
Step-by-step explanation:
23 + 23 + 23 + 23 + 23 + 23 + 23 + 23 +23 + 23 23 + 23 +23 + 23 = 322
Answer:
Ignacio can make 5 clockwise rotations.
Step-by-step explanation:
Given that the Ignacio's legs are already at a height of 49.3cm and each rotation of the chair knob raises his legs another 4.8cm, we can set up an inequality to determine the number of rotations Ignacio could make without his legs touching the desk, which is at a height of 74.5cm:
4.8r + 49.3 < 74.5 where 'r' is equal to the number of rotations
The sum of the Ignacio's original leg height plus the amount of height increased from the rotations of the know must be less than 74.5 in order for his legs not to touch. Now, solve for 'r':
Subtract 49.3 from both sides: 4.8r + 49.3 - 49.3 < 74.5 - 49.3 or 4.8r < 25.2
Divide 4.8 from both sides: 4.8r/4.8 < 25.2/4.8 or r < 5.25
Since the number of rotations must be less than 5.25, he can make 5 complete rotations.
