Answer:
Since the above triangle is Iscocleles we can make our equation-
5x - 8 = 2x + 7
5x - 2x = 8 + 7
3x = 15
x = 5

Answer:
7x⁴ + 5x³ + 7x² + 6x + 5
Step-by-step explanation:
The given expression is
(5x4 + 5x3 + 4x - 9) + (2x4 + 7x2 + 2x + 14)
The first step is to open the brackets by multiplying each term inside each bracket by the term outside each bracket. Since the term outside each bracket is 1, the expression becomes
5x⁴ + 5x³ + 4x - 9 + 2x⁴ + 7x² + 2x + 14
We would collect like terms by combining each term with the same exponent or raised to the same power. The term would be arranged in decreasing order of the exponents. It becomes
5x⁴ + 2x⁴ + 5x³ + 7x² + 4x + 2x - 9 + 14
7x⁴ + 5x³ + 7x² + 6x + 5
Answer:
Using points ( 2 , - 4) and ( 0 , 2)
Slope = 2+4/0-2 = 6/-2 = - 3
Since the lines are parallel their slope will be the same
So the slope of the line parallel to the one in the picture is - 3
That's option A.
Hope this helps.
Answer:
lines b and c are perpendicular
Step-by-step explanation:
Use slope
slope for parallel is the same
slope for perpendicular is negative reciprocal
line a slope- 1-3/-2-0 is -2/-2 or 1
line b slope- 1-4/4-6 is -3/-2 or 3/2
line c slope- 3-1/1-4 is 2/-3 or - 2/3
none are the same so none are parallel
- 2/3 is the negative reciprocal of 3/2 so lines b and c are perpendicular
Percent of increase = delta change/total first week x100
delta change = 25- 20 = 5
percent increase = 5/20 x 100 = 100/4 = 25 percent
