The relationship between the distance run and the time for Amy can be represented by the equation Y equals 17.45X, where she ran

Kipish [7]

Question;

Assumption:

Let us assume Brandon's running speed is = 18.30 and

Ruben's running speed is = 16.50 and

Answer:

The two equations that can represent the relationship between the meters and second for Brandon and Ruben are;

Brandon → Y₁ = 18.3·X₁ and

Ruben → Y₂ = 16.5·X₂

Step-by-step explanation:

The equation is of the form

Y = 17.45·X

That is Amy ran Y meters in X seconds

Therefore we have

$17.45 = \frac{Y}{X}$ or the value 17.45 is the running speed of Amy

Therefore, where the running speed of Brandon is 18.30 and the running speed of Ruben is 16.50 we have

Y meters ran by Brandon in X seconds given by

Y₁ = 18.3·X₁ and

For Ruben we have Y meters ran in X seconds given by

Y₂ = 16.5·X₂.

A.The y-intercept of the function is 3.

Marrrta [24]

Answer:

D. The slope of the function is positive.

Step-by-step explanation:

I think the best thing to start with is the slope. Lets figure it out using the slope formula, (y2-y1)/(x2-x1).

Using the points, (-4, -7) and (-3, -4),

(-4 - (-7)) / (-3 - (-4))

= 3 / 1

= 3

Right off the bat, you can see that C is incorrect.

Lets go through the other choices and check now.

Using our slope, lets write an equation in the slope intercept form.

y = -3x + b (derived from y=mx+b)

Now, lets plug in a point (let's say, (-4,-7)) to verify if 3 really is the y intercept.

-7 = 3(-4) + b

-7 = -12 +b

5 = b

Since 3 is not equal to 5, A is incorrect. That leaves us with choice B and D.

We know that the x-intercept is found as (0, a), meaning that this x intercept is (0, 5/3). Let's plug it into the equation!

0 = 3(5/3) + 5

0 = 5 + 5

0 = 10

Since this is obviously incorrect, our answer is D, the slope of the function is positive. Let me know if you have any other questions.

3a-2/3+2a+3/2=a+7/6.find a

S_A_V [24]

I think your question seems to be ;

${\:\implies \quad \sf 3a-\dfrac23 +2a+\dfrac32 =a+\dfrac76}$

So I will be solving for that ;

${\:\implies \quad \sf 3a+2a+\left(\dfrac32 -\dfrac23\right)=a+\dfrac76}$

${\:\implies \quad \sf 5a+\left(\dfrac{9-4}{6}\right)=a+\dfrac76}$

${\:\implies \quad \sf 5a+\dfrac56 =a+\dfrac76}$

${\:\implies \quad \sf 5a-a=\dfrac76 -\dfrac56}$

${\:\implies \quad \sf 4a=\dfrac{7-5}{6}}$

${\:\implies \quad \sf 4a=\dfrac26}$

${\:\implies \quad \sf 4a=\dfrac13}$

${\:\implies \quad \sf a=\dfrac{1}{3\cdot 4}}$

${\:\implies \quad \bf \therefore \quad \underline{\underline{a=\dfrac{1}{12}}}}$
