<span>If we add these two equations together, we can quickly follow the system via the elimination method as the y-terms cancel out. Doing so results in 6x= -30, so x = -5. Plug this in and solve for y. 2*(-5) + 3y = -7, -10 + 3y = -7, 3y = 3, y = 1. The solution is therefore (-5,1).</span>

Answer:

<u>In week 20, Seth will have 80 cards and Matt will have 60.</u>

Step-by-step explanation:

Let's find out the amount of cards that Math and Seth will have in week 20, using the information shown in the graph and table:

Amount of cards Seth has in week 20 = 20 * 4 = 80

The equation to find out the amount of cards, c, Seth has in week w:

c = 4w

Amount of cards Matt has in week 20 = 20 + (2 * 20) = 20 + 40 = 60

The equation to find out the amount of cards, c, Matt has in week w:

c = 20 + 2w

<u>In week 20, Seth will have 80 cards and Matt will have 60.</u>

Answer:

89.0°

Step-by-step explanation:

The segment from the centre of the circle to the chord is a perpendicular bisector, hence

third side of right triangle = 12.7 ÷ 2 = 6.35

The angle subtended at the centre by arc CD is twice the angle subtended by the right triangle at the centre

The triangle from the centre to C is congruent to the triangle from the centre to D

Calculate the angle (Θ ) in the right triangle using the sine ratio

sinΘ = \frac{opposite}{hypotenuse} = \frac{6.35}{9.06}

Θ = sin^{-1} ( \frac{6.35}{9.06} ) ≈ 44.5°

Hence

measure of CD = 2 × Θ = 2 × 44.5 = 89.0°

The equation of the line with a slope of 6 and y-intercept of -1 is:
Andrew [12]

Answer:

\bold{y=6x-1}

Step-by-step explanation:

Hi there!

Since we are given the slope and the y-intercept of the line, we can very easily identify the equation of the line.

Slope-intercept:

y=mx+b

Plug in the values:

\bold{y=6x-1}

Thus, \bold{y=6x-1} is the equation of the line.

Hope it helps! Enjoy your day!
