Solve the system of equations using substitution 4x + 2y = 16 =−12+5

mario62 [17]

Answer:

$x=\frac{70}{11},\:y=\frac{20}{11}$

Step-by-step explanation:

$\begin{bmatrix}4x+2y=16y\\ y=-\frac{1}{2}x+5\end{bmatrix}$

$\mathrm{Substitute\:}y=-\frac{1}{2}x+5$

$\begin{bmatrix}4x+2\left(-\frac{1}{2}x+5\right)=16\left(-\frac{1}{2}x+5\right)\end{bmatrix}$

$Simplify$

$\begin{bmatrix}3x+10=16\left(-\frac{1}{2}x+5\right)\end{bmatrix}$

Isolate x for 3x+10=16(-1/2x+5): $x=\frac{70}{11}$

$\mathrm{For\:}y=-\frac{1}{2}x+5$

$\mathrm{Substitute\:}x=\frac{70}{11}$

$y=-\frac{1}{2}\cdot \frac{70}{11}+5$

$-\frac{1}{2}*\frac{70}{11}+5=\frac{20}{11}$

$y=\frac{20}{11}$

$\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}$

$x=\frac{70}{11},\:y=\frac{20}{11}$

Which of these points lies on the line described by the equation below?

zmey [24]

The equation y – 5 = 6(x – 7) is written in point slope form. Remember, the equation for point slope form is: y - y1 = m(x - x1).

In this equation, -5 is y1, 6 is the slope (m), and -7 is x1.
Lets see if any of the coordinate pairs you gave matches (-7, -5).
Answer C. is the correct answer.

Find the measure of each angle of a regular pentagon. 36° 108° 144° 72°

iragen [17]

Answer:

The Correct Option is Second one 108°.

Hence, the measure of each internal angle of a regular Pentagon is 108°.

Step-by-step explanation:

Given:

A Regular Pentagon.

Accordingly, for a Pentagon, the total of the internal angles is given by,

$\textrm{Total Measure Internal Angles}=(5-2)\times 180\° = 3\times 180\°= 540\°$

In case of a regular Pentagon, all internal angles are equal.

Hence, divide the total above by 5.

$\textrm{Measure of each angle of regular Pentagon}=\dfrac{540}{5}=108\°$

Hence, the measure of each internal angle of a regular Pentagon is 108°.

Measure of two angles is 80 degrees and 55 degrees.Are these supplementary angles?

Contact [7]

Answer:

Step-by-step explanation:

No, because supplementary angles add up to 180 degrees, and these two do not.
