Answer:
Kindly check explanation
Step-by-step explanation:
Given the information above :
A) Cost equation for Newton Telephone company :
y = 8x
Where x = number of minutes used
y = total cost for x minutes
Cost equation for Tryus telephone company :
y = connection fee + (fee per minute * number of minutes)
y = 42 + (2x)
Where x = number of minutes used
y = total cost for x minutes
Amount is in cent
It could be 1.85 meters for an adult bike.
Reasoning Criticism Lisa modeled 2 with a number line (3). Her logical number line is -6.
<h3>What is meant by number line?</h3>
- A number line is a graphical representation of numbers on a straight line. A number line has numbers that are sequentially placed at equal distances along its length.
- It can be extended in any direction indefinitely and is usually represented horizontally. A number line is a horizontal line with mathematical increments spaced evenly.
- The numbers on the line will determine how to answer the number on the line. The number's use is determined by the question that goes with it, such as plotting a point.
- The number line is a straight line with divisions at equal intervals, similar to a scale.
Therefore, Reasoning Criticism Lisa modeled 2 with a number line (3). Her logical number line is -6.

#SPJ1
<span>the correct equation is
- 4j² + 3j - 28 =0
ax² + bx + c,
a = -4, b=3 c =- 28.
The discriminent D = b² - 4.a.cD = 3² - 4(-4)(-28)D = -439
If D ≥ 0 there are either 2 roots or one double if = 0)if D< 0, there are no real roots (but 2 imaginary roots)Since D < 0, then there is no real roots
The answer there is no real roots</span>
Can you let me know when you get the answer?
