Long division here. Divide h^2+3h-10 by h-2 to get h+5. That means when you multiply h-2 by h+5, you get what you started with, h^2+3h-10
Answer:
1 : 2
Step-by-step explanation:
Since the quadrilaterals are similar then the ratios of corresponding sides are equal, that is
= 
= 
Thus the ratio of perimeters is also 1 : 2
Answer:
a; 2,305 houses
b; Year 2002
Step-by-step explanation:
In this question, we are tasked with calculating the number of homes in 2015 and the year when the town will have 1213 houses.
To work with both questions, we will need to go back to the equation of the line
y = 84x + 625
To the first question, since we want to find the number of houses in 2015, we are definitely looking to calculate the value of y here.
hence y = 84(2015-1995) + 625
y = 84(20) + 625
y = 2,305 houses
Kindly note that we had to subtract 1995 from 2015 because we were made to know that 1995 is the y we start to count the number of years making it a point that whatever x value we want to calculate, we need to subtract the value
Now to the second part, we insert the value 1213 here for y so as to get x
1213 = 84x + 625
84x = 1213 - 625
84x = 588
x = 588/84
x = 7 years
Now from the question, we were made to know that x is the number of years since 1995. This means that the year in which the number of houses will be 1213 will be 1995 + 7 years = 2002
Answer:
Quarters = 8
Nickles = 6
Step-by-step explanation:
Call their numbers x and y.
The number equation is
x + y = 14
The value equation is
5x + 25y = 230
5x + 25y = 230-(5x + 5y = 70)
20y = 160
y = 8
x= 6
Answer:
x = -7
Step-by-step explanation:
The vertical line through (-7, -5) will be of the form ...
x = constant
To make the line go through the given point, the constant must be the x-coordinate of that point:
x= -7
