Y=2x+1 x+y=7 pls help meeeeeeeee

Gala2k [10]

Answer:

$y=2,\:x=\frac{5}{2}$

Step-by-step explanation:

$\begin{bmatrix}x+1\cdot \:x+y=7\\ y=2\end{bmatrix}$

x+1· x+2=7

Simplify x+1· x+2: 2x+2x+1· x+2

Add similar elements: x+1· x=2x=2x+2

2x+2=7[ 2x+2=7 ]

Isolate x for 2x+2=7: x=52 2x+2=7

Subtract 2 from both sides

2x+2−2=7−2

Simplify

2x=5

Divide both sides by 2

2x2 =52 Simplify

Solve the equation for the specified variable.<br> T= BA-9, for B<br> What does b=

NARA [144]

9514 1404 393

Answer:

$B=\dfrac{T+9}{A}$

Step-by-step explanation:

Add 9 to both sides of the equation, and divide by the coefficient of B.

T = BA -9

T +9 = BA

(T +9)/A = B

We can rewrite that with B on the left:

B = (T +9)/A

What is the center of the circle whose diameter has endpoints (18, -13) and (4, -3)?

jeka94

Answer:

Step-by-step explanation:

The center of the circle whose diameter has endpoints (18, -13) and (4, -3) will be the midpoint of the coordinates.

The ormua for calculating mid point is expressed as;

M(X,Y) ={(x21+x2/2, y1+y2/2}

X= x1+x2/2

Y = y1+y2/2

From the coordinates

x1 = 18 x2 = 4

X= 18+4/2

X = 22/2

X = 11

y1= -13, y2= -3

Y = -3-13/2

Y = -16/2

Y = -8

Hence the required centre will be at (11,-8)
