Ann: 21
Jim: 31
Miguel: 63
Let’s start by finding Ann’s number.
a + (a + 10) + 3a = 115
5a + 10 = 115
5a = 115 - 10
5a = 105
a = 105 / 5
a = 21
Now, just find the others’ numbers using Ann’s.
Jim sent ten more messages than Ann, and 21 + 10 = 31.
Miguel sent 3 times as many messages as Ann, and 21 * 3 = 63.
Answer:
the answer is the third one 3
Answer:
Step-by-step explanation:
Considering the polynomial 2x⁵ + 4x³ - 3x⁸. The polynomial is not yet in standard form. For a polynomial to be in standard form, the power of the variables must decrease as we progress to the right of the expression.
A) The polynomial in standard form is therefore<u> - 3x⁸ + 2x⁵ + 4x³</u>. <em>We can see that the power are reducing as we move through each terms i.e from 8 to 5 then to 3.</em>
<em />
B) The degree of a polynomial is the maximum degree among all the terms of the polynomial. The term that has the maximum degree is -3x⁸. Hence, the degree of the polynomial is 8
C) There are only 3 terms in the polynomial given. The terms are separated by mathematical signs. The terms if the polynomial are 2x⁵, 4x³ and - 3x⁸.
D) The leading term of the polynomial is the term that comes first after rewriting the polynomial in standard format. Given the standard from of the polynomial given as -3x⁸ + 2x⁵ + 4x³, the leading term will be - 3x⁸
E) Given the leading term to be - 3x⁸, the leading coefficient of the polynomial will be the coefficient of the leading term. The coefficient of -3x⁸ is -3
Answer:
y - 5 = 3(x - 2)
y - 5 = 3x - 6
y = 3x - 1
