Answer:

y=√x+5 -1

the answer is option C,,

x=-7,y=√-7+5 -1=√-2 -1

we can't find the square root of negative values, therefore it displays as error

x=-6,y=√-6+5-1=√-1 -1

same reason

x=-5,y=√-5+5-1=√0-1=-1

x=-4,y=√-4+5-1=√1-1=0

x=-1,y=√-1+5-1=√4-1=1

x=4,y=√4+5-1=√9-1=2

1/2 + 1/3 - 1/4 = I don't know
larisa [96]
Use "PEMDAS"
First we'll add then subtract

\frac{1}{2} + \frac{1}{3} =  \frac{2}{6} +  \frac{2}{6} =  \frac{4}{6}= \frac{2}{3}

\frac{2}{3} -  \frac{1}{4} =  \frac{8}{12} -  \frac{3}{12} =  \frac{5}{12}

\frac{1}{2} +  \frac{1}{3} -  \frac{1}{4} =  \frac{5}{12}

I will make u a brainliest plz help me
satela [25.4K]

Answer: B) Infinitely many solutions; both equations are equivalent

==============================================================

Work Shown:

x+y = 4 ... start with the first equation

x + (-x+4) = 4 ... replace y with (-x+4)

x-x+4 = 4

0x+4 = 4

0+4 = 4

4 = 4 ... this is a true statement regardless of what x you pick

So there are infinitely many solutions. Each solution (x,y) is of the form (x,-x+4). All solutions fall on the line y = -x+4 which is equivalent to x+y = 4. Note how we add x to both sides.

Or you could start with x+y = 4 and subtract x from both sides to get y = -x+4. Either way, we're dealing with the same equation which is why they both graph out the same line.

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC b
iragen [17]

The student made the mistake in Step 2.

It should be m∠o + m∠p = 180 (Supplementary angles)

If this is corrected, then, since m∠m + m∠n + m∠o = 180 from Step 1,

we have,

m∠m + m∠n + m∠o = m∠o + m∠p which is Step 3.

Cancelling m∠o both sides, we get,

m∠m + m∠n = m∠p which is Step 4.

Find the quotient: (x2−5x+8)÷(x+2)
Aneli [31]

Answer:

Quotient = x - 7

Step-by-step explanation:

We are dividing x^2 - 5x +8 by x + 2

x + 2√x^2 - 5x + 8

Starting with dividing by x

x - 7

x + 2√ x^2 - 5x + 8

Multiplying x by x + 2

x

x + 2√ x^2 - 5x + 8

-

x^2 + 2x

= -7x + 8

Step ii, pick -7 for division

-7x + 8

-

-7x - 14

= +8 -(-14)

= 8+14

= 22

The answer is

( x - 7) remainder 22

(x - 7) is the quointent

22 is the remainder
