Answer: His average speed is 8 miles an hour

Step-by-step explanation: First, two halves make a whole, so we simply multiply how many miles he ran in half an hour by 2!

4 x 2 = 8

Hope this helps :)

What is Y=2(3x+6)(5x-4)
Sliva [168]

Answer:

y=30x^2+36x+48 OR f(x)=30x^2+36x+48

This is an exponential function/exponential graph. Hope I helped!

Step-by-step explanation:

Given: y=2(3x+6)(5x-4)

Use the distributive property!: y=(6x+12)(5x-4)

Use the distributive property!: y=(5x(6x+12)-4(6x+12))

Use the distributive property!: y=(30x^2+60x)-(24x+48)

Remove parenthesis: y=30x^2+60x-24x+48y=30x^2+36x+48 OR f(x)=30x^2+36x+48

This is an exponential function/exponential graph. Hope I helped!

please explain the steps that are used to solve this??? Given:2(10 -13x)+9=-34x+60 Step 1:20-26x=-34x+60 Step 2:-26x=-34x+40 Ste
solmaris [256]
You left out the 9 in the whole equation. The 1st step you had right you just forgot to put +9. 2nd step you are combining the like terms and get 11-26x=-34x+40. Step 3: you are trying to isolate the x on one of the sides. You need to switch the 11 over to the 40 and get 29. Move -34x over to -26x and get 8x. Step 4 all you are doing in dividing 8 from both sides and get 5.

*HELP PLEASE* <br> Will get BRAINLIEST answer!!!!
photoshop1234 [79]

When solving these proportions we just remember when moving a number from one side to the other if it started in the numerator it ends up in the denominator and vice versa.


I'll do it in two steps here for teaching purposes; it's not too hard to go directly to the answer.


\dfrac{13}{7} = \dfrac{10}{v}


13 v = 7(10)


v= \dfrac{7 \cdot 10 }{13} = \dfrac{70}{13} \approx 5.4
