Which does not describe the same situation y=3x+5

1 answer:

3 0

Given the function. y = 3x + 5

For, x = -3; y = 3(-3) + 5 = -9 + 5 = -4
For x = 1; y = 3(1) + 5 = 3 + 5 = 8
For x = 4; y = 3(4) + 5 = 12 + 5 = 17

Thus the table representing the function is the table with: -3, 1 and 4 as x-values and -4, 8, 17 as y-values.

For x = 0; y = 3(0) + 5 = 0 + 5 = 5
For y = 0; 0 = 3x + 5; 3x = -5 and x = -5/3

Thus the graph of the function is a straight line passing through points (0, 5) and (-5/3, 0).

To illustrate the fuction as a word statement we say that y is five more than three times x

From the given descriptions, the graph does not represent the graph of y = 3x + 5.

Therefore, the one that does not describe the same situation is the graph.

For the following polynomial, find P(a), P(-x) and P(x + h).<br><br> P(x) = 7x-6

torisob [31]

Answer:

Step-by-step explanation:

Hello, please consider the following.

P(a) = 7 * a - 6

P(-x)= 7 *(-x) - 6 = -7x - 6

P(x+h) = 7 * (x+h) - 6 = 7x + 7h - 6

Hope this helps.

Thank you.

Answer:

Step-by-step explanation:

47 + 70 + 9p = 180

117 + 9p = 180

Subtract 117 from both sides

9p = 63

Divide both sides by 9

p = 7

If ghj=lmk with a scale factore of 5:6 find perimeter of ghj

jeyben [28]

Perimeter of the triangle GHJ is 35cm.

<h3>What is perimeter?</h3>

A perimeter is a closed path that includes, encircles, or delineates a one-dimensional length or a shape with two dimensions.

The perimeter's units are equal to the sides of a polygon's length.

Given Data

The perimeter of a triangle is, by definition, the total length of its sides.

Next, the triangle LMK's perimeter is:

ΔLMK = 14+ 11 + 17

ΔLMK = 42

The perimeter of the triangle LMK must be multiplied by the scale factor if both triangles are congruent and the scale factor is 5:6 (which can be written as a fraction: $\frac{5}{6}$ ).

Next, you have that the triangle GHJ perimeter is:

ΔGHJ = 4( $\frac{5}{6}$ )

ΔGHJ = 35

Perimeter of the triangle GHJ is 35cm.

Given f (x) = x2 + 5x + 6, what is f of the quantity 2 plus h end quantity minus f of 2 all over h equal to?

scoray [572]

We want to get the difference quotient for the given function, we will get see that the difference quotient is equal to:

f'(x) = 2x + 5

<h3>The difference quotient:</h3>

For a given function f(x), we define the difference quotient as:

$\lim_{h \to 0} \frac{f(x + h) - f(x)}{h}$

In this case, we have:

f(x) = x^2 + 5x + 6

Replacing that in the difference quotient we get:

$\lim_{h \to 0} \frac{(x + h)^2 + 5*(x + h) + 6 - x^2 - 5x - 6}{h}\\\\\lim_{h \to 0} \frac{x^2 + 2xh + h^2 + 5*x + 5*h + 6 - x^2 - 5x - 6}{h}\\\\\lim_{h \to 0} \frac{ 2xh + h^2 + 5*h }{h}\\$

Now we can cancel the factor h to get:

$\lim_{h \to 0} 2x + h + 5 = 2x + 0 + 5 = 2x + 5$

So the difference quotient is equal to 2x + 5.

M is the midpoint of AB has coordinates(5, −4), if A has coordinates(6,1). What are thecoordinates of B. (1.5pts)?

Alexandra [31]

Answer:

coordinates of A are (11/2, -3/2)

Step-by-step explanation:

midpoint = M(5, −4)

start point = A(6, 1)

endpoint = B(x, y)

equation :

x = m1 × x2 + m2 × x1 y = m1 × y2 + m2 × y1

_____________ _____________

m1 + m2 m1 + m2

x = (1 × 6) + (1 × 5) y= (1 × 1) + (1 × -4)

_____________ ____________

1 + 1 1 + 1

x = (6+5 )/ 2 = 11 / 2 y = (1+(-4))/2+(1-4)/2 = -3/2

∴coordinates of A are (11/2, -3/2)
