<h2>♪Answer : </h2>

»f(x) = 7x² - 3x + 7

  • find f(2) in f(x)

»f(2) = 7(2)² - 3(2) + 7

»f(2) = 7(4) - 6 + 7

»f(2) = 28 - 6 + 7

»f(2) = 29

  • find f(-1) in f(x)

»f(-1) = 7(-1)² - 3(-1) + 7

»f(-1) = 7(1) + 3 + 7

»f(-1) = 7 + 3 + 7

»f(-1) = 17

  • find f(0) in f(x)

»f(0) = 7(0)² - 3(0) + 7

»f(0) = 7(0) - 0 + 7

»f(0) = 0 - 0 + 7

»f(0) = 7

so, f(2) + f(-1) + f(0) is

  • 29 + 17 + 7
  • = 53✅

Which of the following equations represents a line that passes through the points
Nonamiya [84]

Answer:

Option A is correct

A. Neither

Step-by-step explanation:

Given:

Two points are given (2, 15) and (0, 5)

Let (x_{1}, y_{1})=(2,15) and (x_{2}, y_{2})=(0,5)

The slope of the line m=\frac{y_{2}- y_{1}}{x_{2}- x_{1}}

Put all known value in above equation.

m=\frac{5- 15}{0- 2}

m=\frac{-10}{-2}

m=5

So the slope of the line m=5.

The equation of the is

y=mx+b -------------------(1)

Where m is the slope of the line and b is y-intercept of the line.

Take point (0, 5) to compute the value of b.

Put x=0,y=5\ and\ m=5 in equation 1.

y=mx+b

5=5(0)+b

5=0+b

b=5

Take point (2, 15) to compute the value of b.

Put x=2,y=15\ and\ m=5 in equation 1.

y=mx+b

15=5(2)+b

15=10+b

15-10=b

b=5

So the equation of the line is.

y=mx+b

Put m and b value in above equation.

y=5x+5------------(2)

5x-y=-5

add 10 both side in equation 2.

y+10=5x+5+10

y+10=5x+15

y+10=5(x+3)

So the equation of line that passes through the point (2,15) and (0,5) is.

y=5x+5 or 5x-y=-5 or y+10=5(x+3)

Therefore, Neither the following equations represents a line that passes through the points  (2,15) and (0,5).

ss7ja [257]

Answer:

(10, -10)

Step-by-step explanation:

since the point is at the origin, simply multiply.

2 * 5 = 10
