(1,5) (0,3) lie on the line y = 3+2x or not

PolarNik [594]

Answer:

yes

Step-by-step explanation:

To determine if the points lie on the line, substitute the x- coordinate into the equation and if the value agrees with the value of the y- coordinate then the point lies on the line.

(1, 5 )

y = 3 + (2 × 1) = 3 + 2 = 5 ← true

(0, 3 )

y = 3 + (2 × 0 ) = 3 + 0 = 3 ← true

Hence the 2 points lie on the line with equation y = 3 + 2x

Drag each number to the correct location on the table. Each number can be used more than once, but not all numbers will be used.

Ymorist [56]

See the attached figure.
===================================
The first equation is
4x + 2x²(3x-5) = 4x + 6x³ - 10x² = 6x³ - 10x² + 4x
So, The degree of the function = 3 , and the number of terms = 3
============================================================
The second equation is
(-3x⁴ + 5x³ - 12 ) + ( 7x³ - x⁵ + 6 ) = -x⁵ -3x⁴ +12x³ - 6
So, The degree of the function = 5 , and the number of terms = 4
============================================================
The third equation is
(3x² - 3)( 3x² + 3) = 9x⁴ - 9
So, The degree of the function = 4 , and the number of terms = 2

F(x)=4x+1 and g(x)=x^2-5find(f-g)(x)

Vinvika [58]

Answer:

<h2>-x²+4x +6</h2>

Step-by-step explanation:

Given f(x)=4x+1 and g(x)=x²-5

(f-g)(x) is derived by taking the difference of both functions

(f-g)(x) = f(x)-g(x)

(f-g)(x) = 4x+1 - (x²-5)

(f-g)(x) = 4x+1-x²+5

(f-g)(x) = -x²+4x +6

This gives the requires expression
