Answer:
The answer to the first question is (5,1).
Answer:
?
Step-by-step explanation:
Dam what kind of math u doing
5.
3x - 1 = x + 9
Subtract x on both sides
2x - 1 = 9
Add one on both sides.
2x = 10
Divide by 2 to get the x.
x = 5
Hope this helps!
Hello! And thank you for your question!
First move all the terms to one side:
<span>x^<span><span>2</span><span></span></span></span>−4x−9−29=<span>0
</span>
Then simplify x^2−4x−9−29:
<span><span><span>x<span><span>^2</span><span></span></span></span>−4x−38=0</span><span>
Then use the quadratic formula:
x = 4 + 2</span>√42 over 2 , 4 - 2√42 over 2
Finally simplify:
x = 2 + √42, 2 - √42
Final Answer:
x = 2 + √42, 2 - √42
</span>
56/72 can be simplified to 14/18, then to 7/9 *dividing by 4, then by 2*
28/32 can be simplified to 7/8 *dividing by 4*
70/90 can be simplified to 7/9 *dividing by 10*
7/9 and 7/9 are equivalent, so 56/72 and 70/90 are equivalent.
