Answer: 1/2

Step-by-step explanation: we have formula y = mx + b

x - 2y = 4

2y = x - 4

y = x/2 - 4/2

y = x/2 - 2

m = 1/2

The graph of f(x) = StartRoot x EndRoot is reflected across the x-axis and then across the y-axis to create the graph of functio

allsm [11]

Answer:

The true statements:

The only value that is in the domains of both functions is 0.

The range of g(x) is all values less than or equal to 0.

==================================

Step-by-step explanation:

See the attached figure:

As shown: f(x) = √x with blue color

When f(x) is reflected across the x-axis the result will be (-√x) with red color.

Then the is reflected result across the y-axis to create the graph of function g(x) = -√(-x) with green color.

Domain of f(x) = [0,∞) & Range of f(x) = [0,∞)

Domain of g(x) = (-∞,0] & Range of g(x) = (-∞,0]

So, according to previous, we will check the statements:

1) The functions have the same range. (Wrong)

2) The functions have the same domains. (Wrong)

3) The only value that is in the domains of both functions is 0. (True)

4) There are no values that are in the ranges of both functions. (Wrong)

5) The domain of g(x) is all values greater than or equal to 0. (Wrong)

6) The range of g(x) is all values less than or equal to 0. (True)

Answer:

The second: $\bold{f (x) =4(x+\frac34)^2-\frac{21}4}$

Step-by-step explanation:

$f (x) =4x^2+6x-3\\\\f (x) =4(x^2+\frac64x]-3\\\\f (x) =4[x^2+2\cdot x\cdot\frac34+(\frac34)^2-(\frac34)^2]-3\\\\f (x) =4[(x+\frac34)^2-(\frac34)^2]-3\\\\f (x) =4(x+\frac34)^2-4(\frac34)^2-3\\\\f (x) =4(x+\frac34)^2-\frac94-\frac{12}4\\\\\underline{f (x) =4(x+\frac34)^2-\frac{21}4}$

Please explain the answer

Answer:

yes

Step-by-step explanation:

The side lengths satisfy the Pythagorean theorem, so the triangle is a right triangle.

7.5² +10² = 12.5²

56.25 +100 = 156.25

_____

You may recognize that the ratios of side lengths are ...

7.5 : 10 : 12.5 = 3 : 4 : 5

A 3-4-5 triangle is a well-known right triangle, as this is the smallest set of integers that satisfy the Pythagorean theorem. They also happen to be consecutive integers, so form an arithmetic sequence. Any arithmetic sequence that satisfies the Pythagorean theorem will have these ratios.

_____

If you're familiar with trigonometry, you know the law of cosines tells you ...

c² = a² + b² - 2ab·cos(θ) . . . . where θ is the angle between sides a and b. This reduces to the Pythagorean theorem when θ=90°, which makes cos(θ)=0. If the sides do not satisfy the Pythagorean theorem, cos(θ)≠0 and the triangle is not a right triangle.

Cassandra wants to solve the equation 30=2/5p.Whta operation should she perform to isolate the variable?

frosja888 [35]

Well, if you want to get p by itself, you will have to multiply both sides by 5/2. 2/5 times 5/2 gives you 1p, or just p.
