Answer: Can I see an image of the word problem?
Answer:(6,4)
Step-by-step explanation: y=4
y=2x-8
4=2x-8
X=6
Y=4
25 degrees
15-25=-10
-10+25=15
7.5y - z/9 + 50 + 2y
Okay, so it would be best to organize and simplify this expression: 9.5y -z/9 + 50
Alright, now let's eliminate some answers.
True or false: The constant is 7.5. This is <em>false. </em>7.5 is a coefficient, 50 is a constant.
True or false: The coefficients are 7.5 and -9. This is <em>false. </em>Sure, 7.5 is a coefficient, but -9 is not. Actually, z/9 is also equal to (1/9)z, so <em>technically </em>1/9 is the coefficient.
True or false: The variables are x and y. This is <em>false. </em>Where is x? Nonexistent.
True or false: The like terms are 7.5y and 2y. This is <em>true. </em>When we simplified the equation, we first combined like terms. 7.5y and 2y are like terms and therefore able to be combined. That's how we got 9.5y.
The answer, I believe, is D. Hope this helps!
“A” : because a proportional relationship has to go through the origin. “A” has a y-intercept of 8 so it’s not considered proportional.
