Write y + 1 = –2x – 3 in standard form.
sladkih [1.3K]

Answer:

b) 2x + y = -4

Step-by-step explanation:

To go from the Point-Slope Formula [y - y₁ = m(x - x)₁] to the Slope-Intercept Formula [y = mx + b], move -1 to the RIGHT side of the equivalence symbol to get this: y = -2x - 4. Although this is a correct answer choice, this is NOT what the question is looking for because you have to go an extra step further, Standard Formula. To go from the Slope-Intercept Formula to the Standard Formula [Ax + By = C], move 2x to the LEFT side of the equivalence symbol, and you will end up with this: 2x + y = -4. So, your answer is b).

The measures of the angles in a triangle are in the ratio of 2:2:4. Find the exterior
scoray [572]

Given:

The measures of the angles in a triangle are in the ratio of 2:2:4.

To find:

The exterior angle that is adjacent to the largest angle.

Solution:

Let the interior angles of the triangle are 2x, 2x and 4x respectively.

According to the angle sum property, the sum of interior angles of a triangle is 180 degrees.

2x+2x+4x=180^\circ

8x=180^\circ

x=\dfrac{180^\circ}{8}

x=22.5^\circ

Clearly, x=22.5>1, so 4x is the largest angle between 2x, 2x and 4x.

Now,

\text{Largest angle}=4x

\text{Largest angle}=4(22.5^\circ)

\text{Largest angle}=90^\circ

Let the required exterior  angle that is adjacent to the largest angle be y.

Interior angle and adjacent exterior angles are supplementary, so their sum is 180 degrees.

\text{Largest angle}+y=180^\circ

90^\circ+y=180^\circ

y=180^\circ-90^\circ

y=90^\circ

Therefore, the exterior  angle that is adjacent to the largest angle is 90°.
