<span>What is the simplified form of the expression 7[63÷(5^2-2^2)-1]?
</span>7[63÷(5^2-2^2)-1]
= 7[63÷(25-4)-1]
= 7[63÷(21)-1]
= 7[3-1]
= 7 (2)
= 14
answer is <span>C. 14
</span><span>Which is a solution of the equation y=4x+3?
answer is
C. (4,19)
</span>y=4x + 3
19 = 4(4) +3
19 = 16 +3
19 = 19
1. x=3.03
2.x=0.5
3.x=4/3
4.x=2
5.x=10
Answer:
y=1/2x-3
gradient = 1/2
also should satisfy the given coordinates
Answer:
Any radical in the form can be written using a fractional exponent in the form . The relationship between and works for rational exponents that have a numerator of 1 as well. For example, the radical can also be written as , since any number remains the same value if it is raised to the first power.
