Y = - 5 x + 10
A ) x = - 15, y = 5
5 = 75 + 10
5 ≠ 85
B ) x = 2, y = 0
0 = - 5 · 2 + 10
0 = 0  ( correct )
C ) x = - 1,  y = - 5,
- 5 = 5 + 10
- 5 ≠ 15
D ) x = 3, y = 25
25 = - 15 + 10
25 ≠ - 5

4 0

Answer:

B. (2,0)

Step-by-step explanation:

The given equation is;

y=-5x=10

If an ordered pair is a solution, then the ordered pair must satisfy the given equation.

For (-15,5),we have

5=-5(-15)+10

5=75+10,this is FALSE.

For (2,0), we have

0=-5(2)+10

0=-10+10, this is TRUE

For (-1,-5), we have;

-5=-5(-1)+10

-5=5+10, this is FALSE.

For (3,25), we have;

25=-5(3)+10

25=-15+10, this is FALSE

Consider the functions: f(x) = x2 + 4x – 1 and g(x) = 2x + 5. See graphs alongside. a) Identify each curve b) Find the coordinat
Nutka1998 [239]

Step-by-step explanation:

try the option shown in the attachment.

Finally,

A(-2-\sqrt{3};0);

B(-1-\sqrt{7};3-2\sqrt{7});

C(-2+\sqrt{3};0);

D(-1+\sqrt{7};3+2\sqrt{7});

E(0;5);

F(-\frac{5}{2};0);

G(-2;-5).

in order to calculate the points E & F it is needed to solve the equations y=2*0+5 and 2x+5=0;

in order to calculate the vertex G it is needed to find x-coordinate:

x=(-4)/(2*1)=-2 and to substitute x=-2 into y=x²+4x-1 (y=-5).
