Answer:
If you solve by substitution then the answer for the first one would be (−7,−7) or x=−7,y=−7 and the second has no solution
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Please tell me if this is right
Answer:
128.7
Step-by-step explanation:
81.90 ÷ 7 = 11.7
11.7 x 11 = 128.7
Answer: a = c^(1/2) which is the first answer choice of the list
Work Shown:
a = b^(2/3) ... given equation
a = (c^(3/4))^(2/3) ... replace b with c^(3/4)
a = c^((3/4)*(2/3)) .... multiply exponents
a = c^(1/2) .... Simplify; note the 3's cancel, also 2/4 turns into 1/2
Answer:
115
Step-by-step explanation:
The measure of x is half the sum of the intercepted arcs. The arc on the left is a semicircle, so 180°.
The arc on the right is the difference between 180° and the two arcs shown, 60° and 70°, so is 180° -60° -70° = 50°.
Then half the sum of the intercepted arcs is ...
x° = (180° +50°)/2 = 230°/2 = 115°
x = 115
The Answer is -3/2
Below is how I got that answer
(-12) / 6+2
-12/ 8 (Simplify the problem by adding 6 and 2, remove the parenthesis).
-3/2 (Simplify -12/8 by dividing it by 4)
