Answer:

<em>i got u</em>

<em>Answer: </em>

<em>The slope is  </em>

<em>− 2 5 . </em>

<em>The y-intercept is  </em>

<em>1 . </em>

<em>The point is  </em>

<em>( 0 , 1 ) . </em>

<em>The x-intercept is  </em>

<em>2 5 . </em>

<em>The point is  </em>

<em>( 2 5 , 0 ) . </em>

<em> </em>

<em>Explanation: </em>

<em>y < − 2 5 x + 1 </em>

<em> is in the slope-intercept form of a linear equation,  </em>

<em>y = m x + b , where  m </em>

<em> is the slope and  b </em>

<em> is the y-intercept. The y-intercept is the value of  y </em>

<em> when  x  is  0 . </em>

<em>Find the  </em>

<em>x  and  y </em>

<em> intercepts. </em>

<em> </em>

<em>The y-intercept is  + 1 . </em>

<em> </em>

<em>The point for the y-intercept is  </em>

<em>( 0 , 1 ) . </em>

<em>Find the  x </em>

<em> intercept by substituting  </em>

<em>0  for  y </em>

<em> and solving for  </em>

<em>x .  0 = − 2 5 x + 1  </em>

<em>Subtract  1 </em>

<em> from both sides. </em>

<em> − 1 = − 2 5 x </em>

<em> </em>

<em>Multiply both sides by  </em>

<em>5 5 × − 1 = − 2x − 5 = − 2 x </em>

<em> </em>

<em>Divide both sides by  − 2 .  − 5 − 2 = x5 2 = x  </em>

<em>Switch sides. </em>

<em> x = 5 2 </em>

<em>The x-intercept is  </em>

<em>5 2 . </em>

<em>The point for the x-intercept is  </em>

<em>( 5 2 , 0 ) . </em>

<em> </em>

<em>Plot the two points on a graph. Draw a straight dashed line through the points to indicate that the line is not part of the inequality. Then shade the area below the line. </em>

An 8-sided die is formed when two square pyramids are attached by their bases. The perimeter of the base shape is 6 centimeters.
lawyer [7]

Answer:

7.5cm²

Complete question:What is the surface area of the 8-sided figure?

Step-by-step explanation:

Consider the half of the 8-sided die i.e the pyramid ABCDE:

As the base is 6 of the perimeter, so each side of the base is 6/4=3/2

Now, the distance between the tallest points is 2 cm, so the height of Pyramid ABCDE is 1 cm.

Considering the right triangle EOM:

EO=1, OM= 3/4 (it is half of AB=3/2) and EM is the hypothenuse, so by the pythagorean theorem length of EM is 

\sqrt{1+ ( \frac{3}{4} )^{2} }=  \sqrt{1+ \frac{9}{16} }= \sqrt{ \frac{25}{16} }= \frac{5}{4}   (cm)

5. So side EBC has area  

\frac{1}{2}BC*EM=  \frac{1}{2}* \frac{3}{2}* \frac{5}{4}= \frac{15}{16}

6. The total area is 8*Area(EBC)=8* \frac{15}{16}= \frac{15}{2}=7.5 ( cm^{2} )

7. for normal situations, the minimum speed limit throughout the u.s. interstate highway system is 72 km/hr which is 45 miles pe
gladu [14]

Answer:

Question 7: Distance = 237.6 km

Question 8: Distance = 399.3 km

Step-by-step explanation:

Question 7:

Given:

Minimum speed (s) = 72 km/hr

Time taken (t) = 3.3 hours.

We know that, distance traveled is equal to the product of speed and time.

Therefore using distance formula, we get:

Distance = Minimum speed × Time

Distance = s\times t

Distance = 72\times 3.3 = 237.6\ km

Therefore, distance traveled at this speed is 237.6 km.

Question 8:

Maximum speed (S) = 121 km/hr

Time taken (T) = 3.3 hours.

We know that, distance traveled is equal to the product of speed and time.

Therefore using distance formula, we get:

Distance = Maximum speed × Time

Distance = S\times T

Distance = 121\times 3.3 = 399.3\ km

Therefore, distance traveled at this speed is 399.3 km.
