What is the degree of x raise to 3 - x raise to 2 y raise to 2 + 2 |
|
Answer» Answer: 4 Step-by-step explanation: x³ - x²y² +2 The degree for a polynomial with ONE variable is the largest exponent of that variable (or term). But the degree of a polynomial having TWO or more variables is the largest sum of the degrees of the terms. Degree of x³ = 3 Degree of x²y² = 2 + 2 = 4 Degree of 2 = 0 Hence the largest sum among the above 3 is 4. Hence the degree of the given polynomial is 4.

If one angle of a parallelogram is 70 degree find the measure of other angles step by step |
|
Answer» in a PARALLELOGRAM, opposite angles are sane therefore, ANGLE opposite of 70 DEGREE will also be 70 degree and in a parallelogram, adjacent angles are supplementary which add up to 180 degree therefore, 180-70=110° 110 degree will be the angle of its adjacent side now only one angle is remaining to find the angle which is 110 degree, the opposite angle of this will also be 110 degree . thus we found all the angles. Ans- measure of other angles of a parallelogram are 70°,110°, 110°. |

X-y = 10x+y = 4ySolve that by elimination: |
|
Answer» Answer: For 2 EQUATIONS, you NEED to EITHER eliminate one or SUBSTITUTE one into another. By elimination: (eliminate y from the equation) Add both equations together. x+y+x-y = 10+4 2x=14 x=7 Then substitute the value of x into any of the equations. 7-y=4 y=3 By SUBSTITUTION: From one equation, x+y=10 so x=10-y Substitute this equation into the other one. (10-y)-y=4 10–2y=4 2y=6 y=3 Then substitute the value of y into the equation made. x=10–3=7 |

modi spends 60% oh his income and saves the rest. if his income increases by 20% and his expenditures increases by 10%, then what is the percentage increase in his savings |
|
Answer» ★ A man USUALLY spends 60% of his INCOME EVERY month and saves the rest. If his income increases by 20% and his expenses also increases by 10 %, Find the percentage of change in his savings.
———————————————————————————— ★ 10 % ———————————————————————————— ★ Let income of person = Rs. 100 Spent on different expenses = Rs. 60 Savings = Rs. 100 - Rs. 60 = Rs. 40 Now, income after increment of 20 % = 100+ 100 20
×100=Rs.120 Expenses after increment of 10 % = 84 Rs. New saving = 120-84= Rs. 36 Now, percentage of decrease in savings = ( 40−36 /40 )×100=10 % ———————————————————————————— |
