the inverse of y is =x+7

Step-by-step explanation:

y=5x-7

then solve for x

5x=y+7

x=(y+7)/5

then exchange x with y

y=(x+7)/5

What is the area of triangle ABC?<br> A(2,1) B(4,7) C(6,3)

Helen [10]

Answer: 10

Step-by-step explanation:

It appears that $\overline{AC} \perp \overline{BC}$ , so to check if this is the case, we can use the slope formula.

$m_{\overline{AC}}=\frac{3-1}{6-2}=\frac{1}{2}\\m_{\overline{BC}}=\frac{3-7}{6-4}=-2$

Since these slopes are negative reciprocals, we can see that this is the case. So, we can take $\overline{AC}$ as the base of the triangle and $\overline{BC}$ as the height of the triangle, and then use the formula $A=\frac{1}{2}bh$ .

Using the distance formula,

$AC=\sqrt{(6-2)^{2}+(3-1)^{2}}=\sqrt{16+4}=2\sqrt{5}\\BC=\sqrt{(4-6)^{2}+(7-3)^{2}}=\sqrt{4+16}=2\sqrt{5}$

So, the area is $\frac{1}{2}(2\sqrt{5})(2\sqrt{5})=\boxed{10}$

Segments PR and QT are diameters of Circle A.

Dafna11 [192]

Answer:

C. 320

Step-by-step explanation:

Given:

PR and QT are diameters

As we can see in the photo, PR and QR are perpendicular with each other at the angle PAQ => the angle QAR = 90°

=> arc PR = 360°/2 = 180°

=> mTAU = 180° - mRAS -mSAT - mPAU = 180° - 50° + 40° + 40° = 50°

Hence, mPRU = mRAS + mSAT + mTAU + arc PQ

= 50° + 40° + 50° + 180°

= 320°
