Answer:
The linear equation is .
Step-by-step explanation:
Given : A loaf of bread of similar quality in the store costs $1.60. This is the rate for a loaf of bread (the slope). As there is no other cost, your beginning point (y-intercept) is zero.
To find : Write the linear equation y = mx + b for the total cost.
Solution :
The linear equation for the total cost
Where, m is the slope m=1.6
b is the y-intercept b=0
Substitute the value,
Therefore, the linear equation is .

Answer:
D. The correct value of c = 7.4
Step-by-step explanation:
According to Tangent-Secant theorem:
"When a tangent and a secant are drawn from one single external point to a circle, square of the length of tangent segment must be equal to the product of lengths of whole secant segment and the exterior portion of secant segment."
Here, the external length of tangent segment = 10
Also, the length of internal segment is 14 and c.
So, by the SECANT THEOREM:
or, c = 7. 1428
Now, rounding off the value of c = 7. 14 to the nearest tenth, we get
c = 7. 4
Hence the correct value of c = 7.4
