A participant in a 21-mile walkathon walks at a steady rate of 3 per hours. He thinks, "the relationship between the number of m
Gnom [1K]

Answer:

<u>Yes. I agree with his claim because the equation relating the miles left to walk and the number of miles left to walk is :</u> y=-3t+21

Step-by-step explanation:

Given :

  • <em>It's a 21 - mile walkathon</em>
  • <em>The rate at which he is moving is 3 miles per hour.</em>

Let the number of miles walked be x ;

∴,

The number of miles 'y' left to walk will be : y=21-x

<em>Thus the time 't' for which he walked :</em>

t=\frac{distance}{speed} \\t=\frac{x}{3}:

∴

From these equations , we get :

x=21-y\\x=3t\\21-y=3t\\y=21-3t

Thus , when we compare this with y=mx+c ,

y=mx+c\\y=-3t+21\\m=-3,c=21

<u>Thus this is an equation of a Line with slope -3.</u>

What’s the standard form of the quadratic equation
Finger [1]
 y = ax^2 + bx + 7    because when  x = 0 y = 7

when x = -1 y = 14 so we have
14 = a - b + 7
so a - b = 7...............(1)
when x =  1 y = 4
so 4 = a + b + 7
a + b = -3.................(2)
Adding equations (1) and (2) we eliminate b so:-
2a = 4
a = 2
Substitute  a = 2 in equation (1)
2 - b = 7
b = -5 

so our equation is y = 2x^2 - 5x + 7

[Help Asap, I will mark brainliest] In the figure below, g, || l. Find the values of y and x.
ohaa [14]

Answer:

x = 23

y = 110

Step-by-step explanation:

70 and  3x+1 are alternate exterior angles and that means they are equal

70 =3x+1

Subtract 1 from each side

69 = 3x

Divide by 3

69/3 =3x/3

23 =x

70 and y are same side exterior angles and that means they are supplementary ( add to 180)

70+y = 180

y = 180-70

y = 110

Olenka [21]

Answer:

5^2 + h^2 = 10^2

Step-by-step explanation:

This is a clear example of the Pythagorean Theorem, a relation of all sides in a right triangle. The equation itself is a^2 + b^2 = c^2. By simply plugging in the given values into the triangle, you would get the answer.
