Y=6x-11 -2x-3y=-7 solve each system of equation by substitution

Anit [1.1K]

Answer:

(2, 1 )

Step-by-step explanation:

Given the 2 equations

y = 6x - 11 → (1)

- 2x - 3y = - 7 → (2)

Substitute y = 6x - 11 into (2)

- 2x - 3(6x - 11) = - 7 ← distribute and simplify left side

- 2x - 18x + 33 = - 7

- 20x + 33 = - 7 ( subtract 33 from both sides )

- 20x = - 40 ( divide both sides by - 20 )

x = 2

Substitute x = 2 into (1) for corresponding value of y

y = 6(2) - 11 = 12 - 11 = 1

Solution is (2, 1 )

Angle DEF is an inscribed angle on a circle, and m∠DEF = 64°. What is the measure of arc DF?

Svetach [21]

Answer:

128°

Step-by-step explanation:

<u>The measure of an inscribed angle is half the measure of the intercepted arc.</u> That means that the intercepted arc is two times the inscribed angle.

Measure of the inscribed angle DEF is 64°, that means that the measure of the intercepted arc DF is 2×64°, which is 128°.

$m\overset{\huge\frown}{DF} = 2 \times m\angle DE F = 2 \times 64^\circ = 128^\circ$

Which statement about x2 + 10x = 11 is true?

Agata [3.3K]

Equations are statements that have equal values, when compared

The true statement about $x^2 + 10x = 11$ are x = 1 and x = -11

<h3>How to determine the true statement</h3>

The equation is given as:

$x^2 + 10x = 11$

Rewrite as:

$x^2 + 10x - 11 = 0$

Expand

$x^2 + 11x - x - 11 = 0$

Factorize

$x(x + 11) -1( x + 11) = 0$

Factor out x + 11

$(x -1)(x + 11) = 0$

Solve for x

x = 1 or x = -11

Hence, the true statement about $x^2 + 10x = 11$ are x = 1 and x = -11
