Answer:

add the = problome

Step-by-step explanation:

The property of equality is demonstrated moving from step a to step b is linear.

The linear equation is defined as the equation having a degree of one or the power of the variable will be one. The linear equation is represented by y = mx + c. Here y is the variable, m is the slope and, c is the intercept.

Given that  b = 3, and m = 5, and y = mx + b then, b. y = 5x + 3. The equation can be formed as below:-

y = mx + c

y = 5x + 3

Therefore, the property of equality is demonstrated moving from step a to step b is linear.

The two numbers after the three decimal numbers (4,0) are not up to “5”. Meaning that they are just zero.

Answer:

Function is a reflection and dilation of function f.

Step-by-step explanation:

A reflection gives the mirror image of function.

A function can be reflected about an axis by multiplying by -1.

To reflect function about the x-axis, multiply f(x) by -1 to get -f(x).

The correct option is: B. Function h is a reflection and a dilation of function f.

-----------------------

The functions are:

[tex]f(x) = 2^x[/tex]

[tex]g(x) = -3 \times 2^x[/tex]

It can be seed that g is f multiplied by -3.

In the image at the end of this question, it can be seen that the g, the blue graph, is a reflected and dilated version of f, the red graph.

Thus, the correct answer is:

B. Function h is a reflection and a dilation of function f.

Answer: −1−3k

Step-by-step explanation:

Distribute:

(−3+4k)−1(−2+7k)

(-3+4k)+{2-7k}

Eliminate redundant parentheses:

(−3+4k)+2−7k

-3+4k+2-7k

Add the numbers:

−3+4k+2−7k

−1+4k−7k

Add the same term to both sides of the equation:

−1+4k−7k

−1−3k

Answer:

x=-3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−21+6x=3(3x−5)−x

−21+6x=(3)(3x)+(3)(−5)+−x(Distribute)

−21+6x=9x+−15+−x

6x−21=(9x+−x)+(−15)(Combine Like Terms)

6x−21=8x+−15

6x−21=8x−15

Step 2: Subtract 8x from both sides.

6x−21−8x=8x−15−8x

−2x−21=−15

Step 3: Add 21 to both sides.

−2x−21+21=−15+21

−2x=6

Step 4: Divide both sides by -2.

Answer:

f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. ... When written in "vertex form": • (h, k) is the vertex of the parabola, and x = h is the axis of symmetry.

Answer:

y =0.25(x-4 )^{2}-1

Step-by-step explanation:

The formula of vertex form is as follows:

Y = a(x-h)^2+k

h = the x value for the vertex (in this case it is 4)

k = the y value for the vertex (in this case it is -1)

If you input these into the equation you are left with:

Y = a(x-4)^2-1

To find 'a' I just entered this equation into the Desmos calculator and messed around with the value until the y-intercept was (8,3)

I hope this was able to help! ^_^

Step-by-step explanation:

two negatives make a positve

Answer:

-9

Step-by-step explanation:

Whenever you are given an expression, first look at it. Since there are two negative signs in the equation, they cancel out, leaving a nine. The opposite value most likely means that the sign is the opposite, so you end up with -9 as the value.

Answer:

C. Two distinct lines are parallel if they are in the same plane and never intersect each other.

Step-by-step explanation:

Parallel lines are best defined as 2 different lines that are in the same plane and will never intersect each other at any point in the graph.

They are always the same distance apart and will never touch.

So, C is correct

Answer:

C

Step-by-step explanation:

The very definition of parallel lines is that they have the same slope, if they have the same slope, they will never meet.

Answer:

m∠1 + m∠3 = m∠2 + m∠4

Step-by-step explanation:

In the figure attached,

In the given trapezoid if two sides AB and CD are parallel and AD is a transverse,

m∠1 + m∠3 = 180°

Similarly, if AB and CD are parallel and BC is a transverse,

m∠2 + m∠4 = 180°

Therefore, m∠1 + m∠3 = m∠2 + m∠4 is the relation between these angles.

Answer/Step-by-step explanation:

The equation, [tex] \frac{20}{x} = -5 [/tex] has one solution, x.

The value of x that will make the equation true, that is the number we can substitute for x into the equation that will make what we have on our left side equal to what we have on our right side is -4.

Substitute -4 for x in the equation and simplify:

[tex] \frac{20}{-4} = -5 [/tex].

Simplifying the equation:

[tex] -5 = -5 [/tex] (this is true).

A value of x that can make the equation false is 4.

Thus, replace x with 4, then simplify.

[tex] \frac{20}{x} = -5 [/tex]

[tex] \frac{20}{4} = -5 [/tex]

[tex] 5 = -5 [/tex] (false. 5 ≠ -5)
