Answer:

y ≥ -2

Step-by-step explanation:

5y - 3 ≥ -13

+3 +3

5y ≥ -10

5/5y ≥ -10/5

y ≥ -2

and since we didn't divide by any negative numbers the sign stays the same

In the diagram below, we have ST parallel to QR. angle P= 40 degrees, and angle Q= 35 degrees. Find the measure of angles STR in

Drupady [299]

Answer:

$m\angle S = 35^\circ, \ m\angle T = 105^\circ,\ m\angle R = 105^\circ$

Step-by-step explanation:

<u>Similar Triangles</u>

Lines ST and QR are parallel. Thus, angles S and Q are congruent, and angles T and R are congruent.

Considering the triangle PQR, the sum of its internal angles must be 180°:

$m\angle P + m\angle Q + m\angle R = 180^\circ$

Substituting the known values:

$40^\circ + 35^\circ + m\angle R = 180^\circ$

Solving for R:

$m\angle R = 180^\circ - 40^\circ - 35^\circ$

$m\angle R = 105^\circ$

Angles S and Q are congruent, thus

$m\angle S = 35^\circ$

Angles T and R are congruent, thus

$m\angle T = 105^\circ$

Summarizing:

$\mathbf{m\angle S = 35^\circ, \ m\angle T = 105^\circ,\ m\angle R = 105^\circ}$

Determine the solution to the equation x²6x=-13

Citrus2011 [14]

Answer:

x = $\frac{\sqrt[3]{468}}{6}$

or x =~ -1.29399

Step-by-step explanation:

Calculate the product. x^2 * 6x = 6x^3

divide both sides by 6. x^3 = -13/6

Take the root of both sides. x = $\frac{\sqrt[3]{468}}{6}$
