Answer: 61 people have worked on this worksheet so far.
Step-by-step explanation:
Given: 80% people try to do this ratio and proportion worksheet find they need some help with the problems.
Let x be the total number of people worked on this worksheet so far.
People need some help with the problems. =80% of x = 0.80x
As per given,
0.80x=49

Hence, 61 people have worked on this worksheet so far.
Answer:
The number before a variable. For example, 4x. 4 would be the coefficient, and x would be the variable.
Answer:
C
Step-by-step explanation:
The exponent is negative so you put the number under 1 with the exponent positive
Answer:
{-2, -1, 1}
Step-by-step explanation:
Domain is a list of x values
=
{-2, -1, 1}
The answer is D) y = 3x^2 - 2, because the x is squared, making the function a quadratic function. Quadratic functions will be in the shape of a parabola (a u or upside down u).
Meanwhile any function whose degree (highest exponent of x) is one is a linear function. It will have be a straight line.
