Answer:

y = 2 + x

Step-by-step explanation:

Line is passing through the points (0, 2) and (1, 3)

y-intercept (b) = 2

Slope of line (m) = (3 - 2)/(1 - 0) = 1/1 = 1

Equation of line in slope intercept form is given as:

y = mx + b

Plugging the values of m and b.

y = 1x + 2 = x + 2

y = 2 + x

Answer:

D. Y = x + 2

Step-by-step explanation:

The slope increases at a rate of 1 / 1, which is written as just x. The line starts at 2, which is at the y-intercept, a.k.a, where you get the +2 from.

for In the given expression, calculate as indicated. Express your answer as a single polynomial in standard form. 4x^(3)-2x^(2)

matrenka [14]

Answer:

The polynomial in standard form is $y = 14 + 6\cdot x - 8\cdot x^{2}+4\cdot x^{3}$ .

Step-by-step explanation:

A polynomial in standard fulfills the following condition:

$y = \Sigma_{i=0}^{m}\,c_{i}\cdot x^{i}$ , $\forall\,i\in \mathbb{N}$ , $0 \leq i \leq m$

Let be $y = (4\cdot x^{3}-2\cdot x^{2}+9)-(6\cdot x^{2}-6\cdot x + 5)$ , which is now handled algebraically:

1) $(4\cdot x^{3}-2\cdot x^{2}+9)-(6\cdot x^{2}-6\cdot x + 5)$ Given

2) $(4\cdot x^{3}-2\cdot x^{2}+9) +(-1)\cdot (6\cdot x^{2}-6\cdot x + 5)$ $(-1)\cdot a = -a$

3) $(4\cdot x^{3}-2\cdot x^{2}+9) +[(-1)\cdot (6\cdot x^{2})+(-6\cdot x)\cdot (-1)+5]$ Definition of substraction/Distributive property

4) $(4\cdot x^{3}-2\cdot x^{2}+9)+(-6\cdot x^{2}+6\cdot x + 5)$ $(-1)\cdot a = -a$ / $(-a)\cdot (-b) = a\cdot b$

5) $4\cdot x^{3}+ (-2\cdot x^{2}-6\cdot x^{2})+6\cdot x + (9+5)$ Associative and commutative properties

6) $4\cdot x^{3}-8\cdot x^{2}+6\cdot x + 14$ Distributive property/Definition of addition

7) $14 + 6\cdot x -8\cdot x^{2}+4\cdot x^{3}$ Commutative property/Result

The polynomial in standard form is $y = 14 + 6\cdot x - 8\cdot x^{2}+4\cdot x^{3}$ .

The expression 2x−(2x+3)2+4(x−1)+x3 can be simplified into the form Ax3+Bx2+Cx+D. Find the missing constants A, B, C, and D belo

Talja [164]

Answer:

Step-by-step explanation:

Before solving this we have to know that,

(-) ×(-)=(+)

(+)×(+) =(+)

(+)×(-)=(-)

Lets solve now,

$2x-(2x+3)2+4(x-1)+x^{3} \\2x-(2x-3)^{2} +4x-4+x^{3} \\2x-(4x^{2} -12x+9)+4x-4+x^{3} \\2x-4x^{2} +12x-9+4x-4+x^{3} \\2x+12x+4x-4x^{2} -9-4+x^{3} \\14x-4x^{2} -13+x^{3} \\\\So,\\x^{3} -4x^{2} +14x-13\\\\Therefore,\\A = 1\\B = (-4)\\C = 14\\D = (-13)$

Hope this helps you

Let me know if you have any other questions :-)

WITCHER [35]

Step-by-step explanation:

$8 {x}^{8} + 28 {x}^{6} + 18 {x}^{4} \\ \\ = 2 {x}^{4} (4 {x}^{4} + 14 {x}^{2} + 9) \\ \\ \therefore \: Ax^B = 2 {x}^{4} \\ \\ \implies \: A = 2 \: \: \: \: \\\\\& \: \: \: \: \: \: \: \:B = 4$
