Answer:
19
Step-by-step explanation:
After x days, the boy will have read 10x. If this is less than 192, we have ...
10x < 192
x < 192/10
x < 19.2
If x is an integer, the largest possible value x could have is 19.
Y = 7x-2
Y = 7(4) -2
Y = 28-2
Y= 26
If that's what u mean!
If I helped mark as the Brainliest! I will really apppreciate that! Thankyou !
Add up all the numbers than divide by how many number they are so when you add them all you get 4432, divide it by 10.
For others, your answer is 443.2.
Answer:
Base = x = 18ft
Height = x - 4 = 14ft
Step-by-step explanation:
The formula for the area of A the triangle is given by the following equation:
1) A = (base * heigth)/(2)
From this problem, we know that
base = x and that the height is 4ft less than the base, so height = base - 4 = x - 4.
We also know that the area is 126ft², so A = 126 ft². Now we can replace these informations in equation 1).
126 = (x(x-4))/2
x² - 4x = 252
x² -4x - 252 = 0
The roots of this equation are x = 18 or x = -14. But we know that a triangle cannot have negative dimensions, so we use x = 18.
The base is x, so base = 18ft.
Height is 4ft less than the base, so height equals 18-4 = 14ft
Answer:
y = -8
Step-by-step explanation:
Since the line is perpendicular to the y-axis, it will be a horizontal line that runs through (-4,-8).
When a line is perpendicular to the y-axis, the x-coordinate doesn't matter because the line will be horizontal, meaning it will be the same y value regardless of the x value. In this case, the y value is −8 throughout the line.
