Find the slope of the line 5x-2y=10A. 2/5B. -5C. -2/5D. 5/2

sammy [17]

5x - 2y = 10

Isolating y:

-2y = 10 - 5x

y = (10 - 5x)/(-2)

y = 10/(-2) + (-5x)/(-2)

y = -5 + 5/2x

This equation has the slope-intercept form with a slope of 5/2 and a y-intercept of -5

nikdorinn [45]

Answer:

160 cups of lemonade and 80 packages of cookies.

Step-by-step explanation:

l = lemonade

c = cookies

l+1.5c=280

2c=l

Substitute.

3.5c=280

Simplify.

c=80

Substitute into the second equation.

l=160.

Plug it back into the equations to check.

His new employer has offered Malcom Davis a choice of profit-sharing plans. For Plan A, he can receive 1/90 of the company’s gro

Strike441 [17]

Malcom Davis earnings is an illustration of equations and proportions.

The equation is: $\mathbf{\frac{1}{90}G= \frac{1}{60}(G- 100000)}$
The gross income must be $300000, for Dave to earn the same amount with either plan.
His earning is $3333.33 when the plans are the same.

Let the profit be P, and the gross income be G.

So, we have:

$\mathbf{P= G - 100000}$

<u>(a) The equations</u>

For plan A, we have:

<em /> $\mathbf{A = \frac{1}{90}G}$ <em> ----1/90 of the company's gross income</em>

For plan B, we have:

<em /> $\mathbf{B = \frac{1}{60}P}$ <em> ----1/90 of the company's profit</em>

When both are the same, we have:

$\mathbf{A= B}$

This gives

$\mathbf{\frac{1}{90}G= \frac{1}{60}P}$

Substitute $\mathbf{P= G - 100000}$

$\mathbf{\frac{1}{90}G= \frac{1}{60}(G- 100000)}$

Hence, the equation is: $\mathbf{\frac{1}{90}G= \frac{1}{60}(G- 100000)}$

<u>(b) Solve the equation in (a), and intepret</u>

$\mathbf{\frac{1}{90}G= \frac{1}{60}(G- 100000)}$

Cross multiply

$\mathbf{60G = 90G - 9000 000}$

Collect like terms

$\mathbf{90G - 60G = 9000 000}$

$\mathbf{30G = 9000 000}$

Divide both sides by 30

$\mathbf{G = 3000 00}$

The gross income must be $300000, for Dave to earn the same amount with either plan.

<u>(c) His earnings based on (c)</u>

We have:

$\mathbf{A = \frac{1}{90}G}$

Substitute $\mathbf{G = 3000 00}$

$\mathbf{A = \frac{1}{90} \times 300000}$

$\mathbf{A = 3333.33}$

His earning is $3333.33 when the plans are the same

<u>(d) If the gross income in less than (b)</u>

If the gross income is <em>less than $300,000</em>, then plan A would better for Malcom Davis, because his earnings in plan A would be <em>greater than </em>plan B

The measure of major arc TBU is_degrees.

Elina [12.6K]

Answer:

46°

Step-by-step explanation:

The alternate segment theorem states that for a circle, the angle between a chord and a tangent through the endpoint of one of the chord is equal to the angle in the alternate segment.

Therefore from the diagram attached, chord TU and the tangent UV form an angle (arc TBU). The alternate segment to arc TBU is ∠ TUV .

Therefore arc TBU = ∠ TUV. But arc TBU = 46°. Therefore:

∠ TUV = 46°
