No, it is a parabola. (assuming that you meant to write 6x² - 2y = 7).

Step-by-step explanation:

If there is a square in the x or y, this gives it away that it cannot be a straight line.

Find RS. A. 5 B. 10 C. 9 D. 12

777dan777 [17]

Answer:

x=9

Step-by-step explanation:

PQ + QR + RS = PS

2x-6 + 1 + x-4 = 18

Combine like terms

3x -9 = 18

Add 9 to each side

3x-9+9= 18-9

3x = 27

Divide by 3

3x/3 = 27/3

x = 9

angle A and angle B are complementary angles. If m angle A = (4x – 28)° And angle B = (4x - 8)°, then find the measure of A.

Flura [38]

Complementary angles have a submission of 90 degrees thus :

$angle \: \: A + angle \: \: B = 90°$

$(4x - 28)° + (4x - 8)° = 90°$

$4x + 4x - 28 - 8 = 90$

Collect like terms

$8x - 36 = 90$

Add both sides 36

$8x - 36 + 36 = 90 + 36$

$8x = 126$

Divide both sides by 8

$\frac{8x}{8} = \frac{126}{8} \\$

$x = 15.75$

_____________________________________________

Now let's find the measure of A :

$A = 4x - 28$

$A = 4 \times (15.75) - 28$

$A = 63 - 28$

$A = 35°$

And we're done...
