Answer:
4.3 cm is the length of the object being measured by caliper
The solutions of the system of equations are (0 , 13) , (3 , 34)
Step-by-step explanation:
To solve an system of equations, one of them linear and the other is quadratic do that
- Use the linear equation to find one variable in terms of the other variable
- Substitute this variable in the quadratic equation
- Solve the quadratic equation to find the values of the other variable
- Substitute the values of the other variable in the linear equation to find the first variable
The system of equation is:
y = x² + 4x + 13 ⇒ (1)
y = 7x + 13 ⇒ (2)
Substitute y in equation (1) by equation (2)
x² + 4x + 13 = 7x + 13
Subtract 13 from both sides
∴ x² + 4x = 7x
Subtract 7x from both sides
x² - 3x = 0
Take x as a common factor
x(x - 3) = 0
Equate each factor by 0
x = 0
x - 3 = 0
Add 3 to both sides
x = 3
The values of x are 0 and 3
Substitute the values of x in equation (2) to find y
When x = 0
y = 7(0) + 13
y = 0 + 13
y = 13
When x = 3
y = 7(3) + 13
y = 21 + 13
y = 34
The values of y are 13 and 34
The solutions of the system of equations are (0 , 13) , (3 , 34)

Cisnero discusses writing three stories in one weekend at Iowa, which later connects with friends workshopping stories in her apartment, to show readers how dedicated she has become to her craft. In this way, she creates the effects of a foreshadowing.
<h3>What is
foreshadowing?</h3>
In literature, foreshadowing refers to the subtle reference to an event that is yet to occur.
Foreshadowing could occur or be deployed in several ways. Some of them are:
- Through the use of dialogue
- Through the use of symbols
- Through the use of character reactions etc.
