Answer
Perimeter = 1.75 times larger
Area = 3.0625 times larger
Step-by-step explanation:
Let the original quadrilateral have sides of a, b, c, d
Perimeter of the New Photograph
- Then the perimeter of the original is P = (a + b + c + d)
- Now the perimeter of the new quad is P = 1.75a + 1.75b + 1.75c + 1.75d
- Using the distributive Property we get P = 1.75(a + b + c + d) So the new perimeter is 1.75*the old perimeter.
Area of the New Photograph
The area is a little harder. Suppose the Old figure had an Area found by the formula of
- Area = e * f Each measurement is increased by a factor of 1.75
- Area_new = 1.75e * 1.75f
- Area_new = 3.0625 * e * f
- Area_new = 3.0625 * old area

Answer:
(10, -2)
Step-by-step explanation:
The inequalities are:
y < x - 7 (1)
y < (1/5)x - 2 (2)
To solve this problem, we have to solve both equations simultaneously and then find the value of x and y that makes the inequality true.
To solve the inequality, subtract inequality (2) from inequality (1) which gives:
0 < (4/5) x - 5
-(4/5)x < -5
Dividing both sides of the equation by -4/5 gives:
-(4/5)x / (-4/5) < -5/ (-4/5)
x > 6.25
Put x > 6.2 in inequality 1
y < 6.25 - 7
y < -0.75
The solution of the inequality is x > 6.25 and y < -0.75
From the list of option, the correct answer is (10, -2) since 10 > 6.25 and -2 < -0.75
Fraction - 1/1 or 1
Decimal - 1
Percentage- 100%
If this is wrong oh well
