A person's Body Mass Index (BMI) is a measure of the mount of fat in their body. The relationship between antioxidant food consu

mption per day in cups and the BMI of an individual is modeled by the following line of best fit: y = -0.1x + 22. Interpret the slope and intercept of the trend line within the context of the data.

Answer:

Check explanation

Step-by-step explanation:

Given:

y = -0.1x + 22

Where,

y = BMI of an individual

x = antioxidant food consumption per day in cups

Equation of a slope

y = mx + c

Where,

m = slope

c = y - intercept

Therefore,

From the equation

y = -0.1x + 22

slope, m = -0.1

y - intercept, c = 22

Solve each equation by graphing the related function. If th equation has no real number solution, write no solution. X^2 + 7 = 0
Brrunno [24]
Answer:
The equation x² + 7 = 0 has no solution

Explanation:
1- using graph:
To solve the equation means graphically means to find the x-intercepts.
The attached image shows the graph of the given function.
We can note that there are no x-intercepts. This means that the given function has no real solutions

2- using algebra:
To solve the equation algebraically means to find the values of x that would make the equation equal to zero.
Solving the given equation, we would find that:
x² + 7 = 0
x² = -7
x = <span>± </span>√-7
The square root of a negative number will always give imaginary values. This means that the equation has no real solutions

Hope this helps :)

A square number and a multiple of 3 have a total of 90 what r the 2 numbers
Alecsey [184]

Hello,

Let's x² the square number

and 3*y the multiple of 3.

x^2+3y=90\\\\\boxed{y=-\dfrac{1}{3} x^2+30}\\\\

2 solutions : for (x,y) as integers : (-6,18) and (6,18)

but one solution for (x²,3y) as integers :<u> (36,54) </u>

Which ordered pair tells the location of the smiley face on the coordinate system?
Jet001 [13]

Answer:

(5,2)

Step-by-step explanation:

You have to look to the X axis and you'll see the smiley face 5 bars/lines across from the vertex or 0.

Next, you'll need to look at the Y axis and see that the smiley face is 2 bars/lines vertically from 0.

So all you need to do is put the numbers into (x,y) and you'll get (5,2)


Hope this helps!
