Answer:

Step-by-step explanation:

Subtract the "Y" values from the ordered pairs -1 - (-7)= 6

Subtract the "X" values from the ordered pairs 1-5 = -4

Remember slope is rise over run or y over x so the answer is -6/4 or -3/2 reduced

I always bring my negative to the top after I finish solving

Since you didn't provide the choices your answer is either going to be 3/-2 or -3/2 depending if your teacher makes you bring the negative to the top

Answer:

-3/2

Step-by-step explanation:

the formula for slope is y1-y2/x1-x2

where

y1 is the first point's y coordinate

x1 is the first point's x coordinate

y2 is the second point's y coordinate

x2 is the second point's y coordinate

so now we can plug our points in

-1-(-7)/1-5

6/-4

simplify

-3/2

Step-by-step explanation:

6x+9=12

6x=12-9

6x=3

x=3/6

x=1/2

---------------

Because 2x+3=4, 2x=4-3, 2x=1, x=1/2.

Mr. Vu can drive his new electric car 194 miles before he needs to charge his battery. How far can Mr. Vu’s car go on 15 battery

const2013 [10]

Answer:

Mr. Vu can go 2910 miles on 15 battery charges (D).

Step-by-step explanation:

If 1 battery charge lasts 194, then we can multiply 15 by 194 to find this amount of miles.

15 times 194 equals 2910, so with 15 battery charges, he would go 2910 miles.

When an object is thrown upwards with a speed of 64 ft/sec, its height above the ground is given by the function h(t)=−16t2+64t

Svet_ta [14]

Answer:

The object will reach its highest point 0.5 seconds after it has been thrown.

Step-by-step explanation:

The object reaches its maximum height when velocity is equal to zero, the velocity is the derivative of function height. That is:

$v(t) = \frac{d}{dt}h(t)$ (1)

Where $v(t)$ is the velocity of the object at time $t$ , in feet per seconds.

If we know that $h(t) =-16\cdot t^{2}+64\cdot t$ and $v(t) = 0\,\frac{ft}{s}$ , then the time when object reaches its highest point is:

$v(t) = -32\cdot t+64$

$-32\cdot t + 64 = 0$

$t = 0.5\,s$

The object will reach its highest point 0.5 seconds after it has been thrown.
