Y=-×+1 and y=2×+4 how many solutions when graphed
dedylja [7]

Answer:

One solution (-1,2)

Step-by-step explanation:

Since these two linear equations have different slopes, different y-intercepts, and are indeed linear, these equations will only have one crossing when graphed, and hence one solution.

To find that solution, we can simply set the equations equal to each other.

y = -x + 1

y = 2x + 4

-x + 1 = 2x + 4

-3 = 3x

-1 = x

Now plug that value back into one of the equations:

y = -x + 1

y = -(-1) + 1

y = 2

So now you know the crossing for these two equations occurs at (-1,2).

Cheers.

Consider the circle where QR = 7 units and UT= 4 units. What is the value of X, if x represents the length of segment ST? A. 15
julia-pushkina [17]

Option C:

x = 6  units

Solution:

QR = 7 units, RS = 5 units, UT = 4 units and ST = x

<em>If two secants intersect outside a circle, the product of the secant segment and its external segment s equal to the product of the other secant segment and its external segment.</em>

⇒ SR × SQ =  ST × SU

⇒ 5 × (5 + 7) =  x × (x + 4)

⇒ 5 × 12 =  x² + 4x

⇒ 60 =  x² + 4x

Subtract 60 from both sides.

⇒ 0 = x² + 4x - 60

Switch the sides.

⇒ x² + 4x - 60 = 0

Factor this expression, we get

(x - 6)(x + 10) = 0

x - 6 = 0, x + 10 = 0

x = 6, x = -10

Length cannot be in negative measures.

x = 6 units

Option C is the correct answer.
