Answer:

(1, - 2 )

Step-by-step explanation:

x + 3y = - 5 → (1)

5x - 2y = 9 → (2)

multiplying (1) by - 5 and adding to (2) will eliminate x

- 5x - 15y = 25 → (3)

add (2) and (3) term by term to eliminate x

0 - 17y = 34

- 17y = - 34 ( divide both sides by - 17 )

y = - 2

substitute y = - 2 into either of the 2 equations and solve for x

substituting into (1)

x + 3(- 2) = - 5

x - 6 = - 5 ( add 6 to both sides )

x = 1

solution is (1, - 2 )

Answer:

Step-by-step explanation:

1 + 3 = 4

so find the point 1/4 of the way from (-1, 2) to (7, 8)

x coordinate

Δx = ¼(7 - (-1)) = 2

x = x₀ + Δx

x = -1 + 2 = 1

y coordinate

Δy =  ¼(8 - 2) = 1½

y = y₀ + Δy

y = 2 + 1½ = 3½

(1, 3½)

Function g can be thought of as a translation (shifted) version of f(x)=x^2
Natasha_Volkova [10]

Answer:

Step-by-step explanation:

f(x)=x^2  represents a parabola with vertex at (0, 0), that opens up.

If we translate this graph h units to the right, then g(x) will be:

g(x) = (x - h)^2.

If we translate the graph of  f(x)=x^2 k units up, then g(x) will be:

f(x)=x^2 + k

Next time, please indicate whether you are shifting the original graph to the right or to the left, and/or up or down.
