Geometry What’s the answer to 5x-6y= 33 and 2x+y = -14

V125BC [204]

Answer:

X=-3 y=-8

Step-by-step explanation:

$5x - 6y = 33 \\ y = - 14 - 2x \\$

Put the second one in first

$5x - 6( - 14 - 2x) = 33 \\ 5x + 84 + 12x = 33 \\ 17x = - 51 \\ x = - 3$

$y = - 14 - 2 \times ( - 3) \\ y = - 8$

Someone please help me

lina2011 [118]

Answer:

$\displaystyle \boxed{\frac{60}{61}} = cos\:θ_1$

Step-by-step explanation:

$\displaystyle arcsin\: \frac{11}{61} ≈ 0,1813197744 \\ \\ cos\:0,1813197744 ≈ \frac{60}{61}$

Since this answer is in Quadrant I, this would be a positive-positive answer, which in this case, will remain a positive.

Extended Information on Quadrants

$\displaystyle Positive-Negative → Quadrant\:IIII \\ Negative-Negative → Quadrant\:III \\ Negative-Positive → Quadrant\:II \\ Positive-Positive → Quadrant\:I \\ \\$

Extended Information on Trigonometric Ratio Values

$\displaystyle y-values → sin\:θ \\ x-values → cos\:θ$

I am joyous to assist you anytime.

A line passes through the points (9,6) and (6,5). What is its equation in slope-intercept form?

Tju [1.3M]

Answer:

Y=X/3+3

Step-by-step explanation:

M= Y2-Y1/X2-X1

= 5-6/6-9

= -1/-3

= 1/3

sub x=6, y=5, M=1/3 into Y=MX+C

5=6/3+C

5=2+C

5-2= 2+C-2

3=C
