Solve the system and enter the smallest x-coordinate first

Mathematics
1 answer:
ankoles [38]1 year ago
4 0
Answer:
(2,-3)(6,5)
Step-by-step explanation:
We can use substitution to get the equation: x^2-6x+5 = 2x-7
Solve:
x^2-6x+5 = 2x-7
x^2 = 8x-12
x^2-8x+12 = 0 (we now have a polynomial)
(x-6)(x-2) = 0 (set each equation to equal 0 and solve)
x-6 = 0 --> x=6
x-2 = 0 --> x=2
To get the Y coordinates:
y=2(2)-7 --> y = -3
y = 2(6)-7 --> y = 5

Check work:
5 = 6^2-6(6)+5 --> 5 = 36-36 +5 --> 5=5
-3 = 2^2-6(2)+5 --> -3 = 4-12+5 --> -3=-3

If the graph of the equation y=(x+2)^2 is reflected with respect to the y-axis, what is the equation of the resulting graph?
alexandr1967 [171]

Answer:

Is important to remember that the reflection of the point (a,b) across  the y-axis is the point (-a,b).

Our original equation is y= (x+2)^2

And after the reflection respect x we got:

y= (-x+2)^2

Step-by-step explanation:

Is important to remember that the reflection of the point (a,b) across  the y-axis is the point (-a,b).

Our original equation is y= (x+2)^2

And after the reflection respect x we got:

y= (-x+2)^2

Find the value of x. Round to
Leno4ka [110]

Answer:

X= 10

Step-by-step explanation:

let the vertex of angle 17° named A

then the other two B and C

then by using trigonometry:

sin(A) = opposite side divided by hypotenuse

opposite side is. X

Wich makes Sin(A) = X/47

then by crossing X= sin(A) × 47 = 13.74147

rounding to the nearest tenth: X= 10

amm1812

Answer:

102

Step-by-step explanation:

The least common multiple of 6 and 17

For us to determine the L.C.M of 6 and 17,

First find the prime factors of 6 and 17

Prime Factor of 6

6 = 2 × 3

Prime factor of 17

17 = 1 × 17

Secondly;

Multiply all the factors together to find the L.C.M:

L.C.M = 1 × 2 × 3 × 17

L.C.M = 102
