How do you do these problems

Mathematics

Elden [556K]3 years ago

Well for the first one, that is presumably a straight line and straight lines all have 180 degrees. So you add 61 and 23 to get 84 and subtract that from 180. You then get 96 degree.

For the second one corresponding angles on a transversal are congruent so x+95=4x-10 and then you solve the equation.;

For the third one you need to make the change from 9 to 12 be the same as the change from 3 to t. 9 to 12 is 4/3 so 3 times 4/3 is 4. t=4

DaniilM [7]

Answer:

Slope of PQ = 0

Slope of MN = infinity

PQ and MN are perpendicular to each other

Step-by-step explanation:

for any two points  (x1, y1),  (x2, y2)given in coordinate plane slope is given by

y1 - y2/x1-x2\\\\For \ line \ PQ\\slope = 2 - 2/-8-4 = 0\\\\For \ line \ MN \\slope = 6 - (-8)/8-8 = 1/0 = infinity\\\\

For any line if slope is zero it is parallel  to X axis and perpendicular to Y axis

For any line if slope is infinity it is parallel  to Y axis and perpendicular to X axis

Also we know X and Y are perpendicular to each other.

Since slope of PQ is zero it is parallel  to X axis and perpendicular to Y axis

Since slope of MN is infinity it is parallel  to Y axis and perpendicular to X axis.

Thus two lines PQ and MN are perpendicular to each other.

The x-intercept of f(x)= log 4^x is?
Naily [24]

Answer:

The x-intercept of this equation is at the point (0,0).

Step-by-step explanation:

The graph starts at the origin because the log of 4^0 = 0.

I graphed the equation on the graph below to show you how I got my answer.

What is the answer of 1/2 x 2 1/3 =
OlgaM077 [116]

Answer:

7/6 or 1 1/6

Step-by-step explanation:

First convert 2 1/3 into just a normal fraction

2 1/3 = 7/3

Next set up the equation and multiply from left to right on both the top and bottom.

1/2 x 7/3 = 7/6

1 x 7 = 7

2 x 3 = 6

Answer: 7/6 or 1 1/6
