In baseball, Shintaro had 4 hits in his last 12 times at bat.
ikadub [295]

For this case we can propose a rule of three according to the Shontaro base performance.

4 hits ------------> 12 times at bat

x -------------------> 36 times at bat

Where "x" represents the number of hits he will have the following week, based on his previous performance.

x = \frac {36 * 4} {12}\\x = 12

So, Shintaro will have 12 hits in 36 times at bat

Answer:

Shintaro will have 12 hits in 36 times at bat

What is the initial value of y= 8x+7
allochka39001 [22]

Answer:

7

Step-by-step explanation:

The initial value is another name for the y-intercept. This equation is written in point slope form (y=mx+b). And before you think y-intercept means y, right? No that is incorrect, I got that wrong in the beginning too ;)

y=mx+b

y=8x+7

b in the point slope form equation is always the initial value or y-intercept or whatever people call it. So what substitutes b out here? 7. So 7 is the initial value!

:) Hope you understand now! Have a good day!

Enter an equation in point-slope form for the line.
MissTica

Answer:

y+1=4(x+2)

Step-by-step explanation:

Hi there!

Point-slope form: y-y_1=m(x-x_1) where m is the slope and (x₁,y₁) is the given point

y-y_1=m(x-x_1)

Plug in the slope and the point

y-(-1)=4(x-(-2))\\y+1=4(x+2)

I hope this helps!
