What is the slope of the line given, f(0) = -5 and f(4) = 11?

Answers

Answer:

The slope is 4.

Step-by-step explanation:

We are given that f(0)=-5 and f(4)=11.

This means that we have the two points (0, -5) and (4, 11).

So, we can use the slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let (0, -5) be (x₁, y₁) and let (4, 11) be (x₂, y₂). Substitute appropriately:

[tex]m=\frac{11-(-5)}{4-0}[/tex]

Evaluate:

[tex]m=\frac{16}{4}=4[/tex]

Hence, the slope of the line given f(0)=-5 and f(4)=11 is 4.

Convert 4/7 to 42nds

1. 4-6 = -2

2. -4- -9 = 5

3. -2/5

Answer:

[tex]-\frac{2}{5}[/tex]

Step-by-step explanation:

slope formula is:

[tex]y2-y1/x2-x1[/tex]

so we plug in the coordinates

[tex](6-4)/(-9--4)[/tex]

which is

[tex]2/-5[/tex]

so the slope is

Which set of transformations would prove ΔQRS ~ ΔUTS?

Reflect ΔUTS over y = 2, and dilate ΔU′T′S′ by a scale factor of 2 from point S.
Reflect ΔUTS over y = 2, and translate ΔU′T′S′ by the rule (x − 2, y + 0).
Translate ΔUTS by the rule (x + 0, y + 6), and reflect ΔU′T′S′ over y = 6.
Translate ΔUTS by the rule (x − 2, y + 0), and reflect ΔU′T′S′ over y = 2.

Answers

Answer:

A

Step-by-step explanation:

The set of transformations would prove ΔQRS ~ ΔUTS is A. Reflect ΔUTS over y = 2, and dilate ΔU′T′S′ by a scale factor of 2 from point S.

How does transformation of a function happens?

The transformation of a function may involve any change.

Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.

Firstly, we need the general rotation method (x,y) to (-y,x)

So; U (-4,-2) becomes U’ (2,-4)

T(-2,0) becomes T’(0,-2)

S(-2,-2) becomes S’ (2,-2)

The set of transformations would prove ΔQRS ~ ΔUTS are;

Reflect ΔUTS over y = 2, and dilate ΔU′T′S′ by a scale factor of 2 from point S.

Thus, option A is correct.

Describe two different ways to solve 8y + 22 = 2y – 12 and tell whether the two solutions will be the same.

(written response)

Answers

8y+22=y-12

First way:
—> subtract 2y and 22 from both sides to get 6y= -34
—> divide both sides to get 3y= -17
—> divide both sides by 3 to get y= -(17/3)

Second way:
—> add 12 to both sides and -8y from both sides to get -6y= 34
—> divide both sides by 2 to get -3y= 17
—> divide both sides by -3 to get y= -(17/3)

There are at least 2 other ways to solve this. This is just two ways. The solution will ALWAYS be the same if you have done it correctly. Y will always = to -(17/3)

Y = -7x + b

Answer:

[tex]y=-\frac{7}{1}x+2[/tex]

Step-by-step explanation:

The slope of -7=

[tex]-\frac{7}{1}[/tex]

so fractional slope is

[tex]y=mx+b[/tex]

Substituting slope into a fraction,

[tex]y=-\frac{7}{1} x+b[/tex]

Point is 0,2 so substitute in x and y.

[tex]2=-\frac{7}{1} (0)+b[/tex]

Solve the equation.
