Simplify the polynomial. Then find its value for the given value of the variable.
(full question attached as image)
Answer:
simplified: xy²value: 4Step-by-step explanation:
The polynomial is simplified by combining like terms. Like terms are identified more easily if the variables in each term are written in the same order. We usually like to use alphabetical order. Two of the like terms have opposite coefficients, so they cancel. The result is ...
(3 1/2 -2 1/2)xy² +(-2 4/5 +2 4/5)x²y
= xy² . . . . simplified expression
__
For x = 1, y = -2, the value of the expression is ...
(1)(-2)² = 4

The two rules are :-
15 - 10(n - 1)
25 - 10n
Answer:
25 - 10n15 - 10(n - 1)Explanation:
sequence: 15, 5, -5, -15, -25
solve:
1st rule 25 - 10n:
25 - 10(0) = 15
25 - 10(2) = 5
25 - 10(3) = -5
25 - 10(4) = -15
25 - 10(5) = -25
second rule using 15 - 10(n - 1):
15 - 10(1 - 1) = 15
15 - 10(2 - 1) = 5
15 - 10(3 - 1) = -5
15 - 10(4 - 1) = -15
15 - 10(5 - 1) = -25

Answer:
18
Step-by-step explanation:
you take away -9 from both sides
27-9=18
Answer:
9
Step-by-step explanation:
so first you send +9 to the right , it will become -9
2p + 9 = 27
2p = 27 - 9
you substract -9 from 27
2p = 18
next step you send 2 to the other side... since it multiply on the left side...it will become divide on the right side, so that p can be alone
2×p = 18
p = 18 ÷2
p = 9
i rewrote it without explication
full step is : 2p = 27 - 9
2p = 18
p = 18 ÷ 2
p = 9
let the marked price be Rs x, s.p is rs 180 and discont percent is 10 percent . find the marked price
Answer:
Step-by-step explanation:
Discount % = 10 %
Discount price = 10% of marked price = 10% of x
Marked price - discount =SP
[tex]x-\dfrac{10}{100}x=180\\\\\\\dfrac{100}{100}x-\dfrac{10}{100}x=180\\\\\\\dfrac{90}{100}x=180\\\\\\x=180*\dfrac{100}{90}=2*100\\\\\\[/tex]
x= 200
Marked price = 200

Answer:
x = 7
Step-by-step explanation:
The 2 right triangles are similar by the AA postulate, then the ratios of corresponding sides are in proportion, that is
[tex]\frac{x}{4}[/tex] = [tex]\frac{3.5}{2}[/tex] ( cross- multiply )
2x = 14 ( divide both sides by 2 )
x = 7
Will recommend to see attached picture as name of angles are based on it.
[tex] \\ [/tex]
We can only find value of x if both triangles i.e triangle DOC and triangle AOB are similar.
[tex] \\ [/tex]
[tex]\sf \underline{In \: \triangle \: DOC \: and \: \triangle\:AOB: }[/tex]
[tex] \\ [/tex]
[tex] \sf1. \angle DOC = \angle AOB[/tex]
Reason :-
VOC (Vertically opposite angle)
How to recognize either it is VOC (Vertically opposite angle) or not?
So it's basically very easy to recognize, when ever u see lines intersect each other just like a multiply sign ( × ) either horizontal or parallel they are considered as VOC ans are always equal.
[tex] \\ [/tex]
[tex] \sf2. \angle CDO = \angle BAO[/tex]
Reason:-
Both are of 90°.
So how we recognized that these both angles were in 90°?
When ever you see that angle is marked in square ( □ ) like shape instead of curve shape then it means the angle is 90°.
[tex] \\ [/tex]
[tex]\sf\triangle \: DOC\simeq \triangle\:AOB: [/tex]
By :- AA (angle angle)
[tex] \\ \\ [/tex]
Now Finally Let's find value of x.
[tex] \\ [/tex]
[tex] \dashrightarrow \sf\dfrac{DC}{AB} = \dfrac{OC}{OB} = \dfrac{OD}{OA} [/tex]
Reason :- Corresponding sides of similar triangle are in proportion.
[tex] \\ [/tex]
So:-
[tex] \\ [/tex]
[tex] \dashrightarrow \sf\dfrac{DC}{AB} = \dfrac{OC}{OB}[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf\dfrac{2}{3.5} = \dfrac{4}{x}[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf\dfrac{3.5}{2} = \dfrac{x}{4}[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf\dfrac{35}{2 \times 10} = \dfrac{x}{4}[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf\dfrac{ \cancel{35}}{2 \times \cancel{10}} = \dfrac{x}{4}[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf\dfrac{7}{2 \times 2} = \dfrac{x}{4}[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf\dfrac{4 \times 7}{2 \times 2} = x[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf\dfrac{ \cancel4 \times 7}{\cancel2 \times 2} = x[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf\dfrac{ 2 \times 7}{1 \times 2} = x[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf\dfrac{\cancel 2 \times 7}{1 \times \cancel2} = x[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf\dfrac{1 \times 7}{1 \times 1} = x[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf\dfrac{7}{1 } = x[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf7= x[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \bf x = 7[/tex]

Which y-intercept is smaller?
-6, -2, 1, or 1 1/2
Answer:
-6
Step-by-step explanation:
if you put all on a number line negitive six is the furthest to the left. meaning its the lowest number
Answer:
Coordinates on a graph cannot be larger or smaller than each other. They are just locations. If you are asking which number has the lowest value, it would be the negative with the highest number. In this case, -6 is the smallest value.

Which choice is equivalent to the expression below?
5^9.969
A. 59+9/10 + 9/10 + 6/1000
B. 59 +59/10 + 66/100
C. 59. 59/10. 56/100 . 59/1000
D. 59.596/10.59/100
==================================================
Explanation:
We can rewrite the exponent 9.969 as 9 + 0.9 + 0.06 + 0.009
Then convert each decimal to a fraction
0.9 = 9/100.06 = 6/1000.009 = 9/1000Your teacher is choosing not to reduce any of these fractions.
Then you'll use this rule [tex]a^{b+c} = a^b*a^c[/tex] to break up the exponent into the pieces mentioned.
So,
[tex]5^{9.969} = 5^{9 + 0.9+0.06+0.009}\\\\5^{9.969} = 5^{9 + 9/10+6/100+9/1000}\\\\5^{9.969} = 5^{9}\cdot 5^{9/10}\cdot 5^{6/100}\cdot 5^{9/1000}\\\\[/tex]
john paid $9.25 for a number of packets of instant noodles costing $1.85 for 5. How many packets of noodles did john buy? If he were to buy 40 packets of the same noodles, would $15 be enough to pay for them?
Every 5 packets cost $1.85
John can afford 9.25 : 1.85 = 5 (times)
So, John bought 5 x 5 = 25 packets of noodles.
If he were to buy 40 packets, he would've had to pay 40 : 25 = 1.6 times more money.
So, he would've had to pay : 9.25 x 1.6 = 14.8 (dollars)
Since 14.8 < 15, $15 would be enough to pay for 40 packets of instant noodles.

where p and q are the roots.
Here the roots are
