Answer: 2

Step-by-step explanation:

The given equation is in slope-intercept form. It is y=mx+b. In this equation, m stands for slope and b stands for y-intercept. Looking back at the equation, we see that in place of m is 2. That tells us that the slope is 2.

The slope is 2.

Remember:

• the formula for the equation of the line is
y = mx + b

Where m = slope, b = y-intercept, and x & y are coordinates

So if

y = mx + b
y = 2x - 5

The 2 is in place of the m which is the slope.

In other words, 2 = m = slope


Therefore, slope is 2.

An archway is modeled by the equation y = -2x2 + 8x. A rod is to be placed across the archway at an angle defined by the equatio
Nata [24]
1) y= - 2x² + 8x. It's a parabola open downward (a<0)  
2) x - 2.23.y + 10.34 = 0 . Re-write it : y = (x/2.23) + (10.34/2.23), a linear equation.
To find the intersections between 1) & 2), let 1) = 2)
-2x² + 8x = (x/2.23) + (10.34/2.23) 
-2x² + 8x - (x/2.23) - (10.34/2.23) =0 ; solve this quadratic for x values:

x' (that is A) = 0.772 & x" (that is B) = 3. (these are the values of x-intercept (parabola with line). To calculate the y-values, plug x' & x' in the equation:
for x' = 0.772, y = 0.34 → B(0.772 , 0.34)
for x" = 3, y = 0.016     → A(3 , 0.O16)
So B IS AT 0.34 Unit from the ground

The graph of f(x)=√x Is shifted four units up and five units to the right. What is the equation of the resulting graph?
RoseWind [281]

A vertical shift adds/subtracts a constant to/from every y-coordinate while leaving the x-coordinate unchanged. A horizontal shift adds/subtracts a constant to/from every x-coordinate while leaving the y-coordinate unchanged. Vertical and horizontal shifts can be combined into one expression.

Shifting up or to the right means add

Shifting down or to the left means subtract

the 3rd option is the correct one

A website charges $0.99 to download a game and a $12.49 membership fee. Write an equation that gives the total cost in dollars (
nata0808 [166]
C = Cost To Download 
M = Membership Fee.
T = 0.99C + M

Now, Plug In 6 For C.
And 12.49 For M
T = 0.99 * 6 + 12.49

0.99*6 = 5.94

T = 5.94 + 12.49

5.94+12.49 = 18.43

T = 18.43.

So, If You Want To Buy 6 Games On The Website, It Will Cost $18.43

Find the missing the side of the triangle A. 130−−−√ m B. 179−−−√ m C. 42–√ m D. 211−−−√ m
LuckyWell [14K]

Answer:

<h2>The answer is option A</h2>

Step-by-step explanation:

Since the triangle is a right angled triangle we can use the Pythagoras theorem to find the missing side

Using the Pythagoras theorem

That's

{a}^{2}  =  {b}^{2}  +  {c}^{2}

From the question

x is the hypotenuse or the longest side of the triangle

Substituting the values into the above formula we have

{x}^{2}  =  {9}^{2}  +  {7}^{2}

{x}^{2}  = 81 + 49

{x}^{2}  = 130

Find the square root of both sides

We have the final answer as

<h3>x = √130 m</h3>

Hope this helps you
