I need help with substitution

Neporo4naja [7]

Answer:

(-7,-15)

Step-by-step explanation:

We can substitute first y in the second y. Both equations are also functions. We can merge the equations.

$2x - 1 = x - 8 \\ 2x - x = - 8 + 1 \\ x = - 7$

Substitute x = -7 in any given equations. I will choose the second equation to substitute in.

$y = x - 8 \\ y = - 7 - 8 \\ y = - 15$

Answer Check

Substitute both x and y in both equations.

$- 15 = 2( - 7) - 1 \\ - 15 = - 14 - 1 \\ - 15 = - 15$

The equation is true for (-7,-15).

$- 15 = - 7 - 8 \\ - 15 = - 15$

The second equation is true for (-7,-15).

Therefore our answer is (-7,-15)

Lines CD and DE are tangent to circle A shown below: If Arc CE is 112°, what is the measure of ∠CDE? a 124° b 136° c 68° d 56°

Elena-2011 [213]

Answer:

Step-by-step explanation:

The central angle of this is 112 degrees. That is CAE is 112 degrees. That being the case, CDE is 90 + 90 + 112 = 292 Tangents make a 90 degree angle with the center of the circle.

CDE = 360 - 292 = 68

(7q3r2 + 5qr2 + 23q) + (−5qr2 − qr² − 11q − 4q3r2) adding polynomials horizontally

zysi [14]

You can remove the parentheses:-

= 7q^3r^2 + 5qr^2 + 23q + −5qr^2 − qr^2 − 11q − 4q^3r^2 ( because there is + outside)

Bring like terms together

= 7q^3r^2 − 4q^3r^2 + 5qr^2 − 5qr^2 − qr^2 + 23q − 11q

= 3q^3r^2 - qr^2 + 12q answer
