Answer:

Option 4. x = 0

Step-by-step explanation:

we know that

The rule of the reflection of a point across the y-axis is equal to

(x,y) -----> (-x,y)

The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the y-value the same

The coordinates of triangle PQR are

P(1, 4), Q(3, 6), and R(5, 2)

Applying the rule of the reflection across the y-axis we have

P(1, 4) -----> P'(-1, 4)

Q(3, 6) ----> Q'(-3, 6)

R(5, 2)----> R'(-5, 2)

The reflection line is the y-axis

Remember that the equation of the y-axis is x=0

therefore

The equation of the reflection line is x=0

What Is the y-intercept of the two points that cross through (8,1) and (-3,1)?
kramer

Answer:

(0,1)

Step-by-step explanation:

The line made by these two points is perfectly horizontal since the value of y in both points is the same. When the y value is the same in all given points, that number is also the y-intercept and the line doesn't cross the x axis.

(The opposite applies as well: If the x value is the same in all given points, that number is also the x-intercept and the line doesn't cross the y axis. In that case, that means the line is vertical)

Emerson struck out 112 times in 350 at-bats. Write a proportion to represent the percent of strike outs per at-bats.
Alex Ar [27]

Answer:

32% of his bats were stuck out.

Step-by-step explanation:

emerson struck out 112 times out of the total of 350 times. therefore, this can be represented as the fraction 112/350, which can be simplified to 8/25.

marta [7]

0 =  - 4.9t {}^{2}  + 27t + 2.4
Convert decimals to fractions

0 =  -  \frac{49}{10} t {}^{2}  + 27t +  \frac{12}{5}
Multiply both sides by 10

0 =  - 49t {}^{2}  + 270t + 24
Move expression to the left.

0 + 49t {}^{2}  - 270t - 24 = 0
Remove zero.

49t {}^{2}  - 270t - 24 = 0Solve the quadratic equation.

t =  \frac{ - ( - 270) +  -  \sqrt{( - 270) {}^{2} - 4 \times 49 \times ( - 24) } }{2 \times 49}
Remove parenthesis and calculate.

t =  \frac{270 +  -  \sqrt{72900  + 4704} }{98}
Add the numbers

t =  \frac{270 +  - 77604}{98}
Separate the solutions

t =  \frac{270  +  \sqrt{77604} }{98}  \\ t =  \frac{270 -  \sqrt{77604} }{98}
The final solution are
t1 =  \frac{270 -  \sqrt{77604} }{98} , t2 =  \frac{270 +  \sqrt{77604} }{98}
