Answer:

(1) False

(2) False

(3). False

(4) False

Step-by-step explanation:

According to the problem, calculation of the given data are as follows,

(1). Given,  149 + 769 = 819

By calculating 149 + 769 = 918  

Hence, False

(2). Given,  556 + 336 = 826

By calculating 556 + 336 = 892  

Hence, False

(3). Given,  458 - 248 = 238

By calculating 458 - 248 = 210  

Hence, False

(4). Given,  658 - 228 = 438

By calculating 658 - 228 = 430  

Hence, False

Hello there!

First of all, find the slope of the right side of the graph. The slope is 2. So far we have:
y=2

Now look at the x coordinate of the point. Now we have:
y=2|x-0|
y=2|x|

Next the graph is shifted down 2 so add a negative two.
y=2|x|-2

I hope this helps!
Best wishes.

URGENTTTTTTTTTTTTT!!!!!!!!!!!

3^3 + 2^7

Step-by-step explanation:

There really is no other way that I can think of other than guessing and checking. 3^3 is 27, when subtracted from 155 gives you 128. 128 can be rewritten as 2^7, leaving your final answer as 3^3 +2^7.

Answer: <em>60°</em>

<em>First let's notice how all of the angles are on a straight line</em>

<em>We know that straight lines must equal to </em><em>180°</em>

<em>Let's take our given angles and add the together </em>

<em>63°+26°+31°=120°</em>

<em>Now we take 180° and subtract is from 120° to give us angle x</em>

<em>180°-120°=60°</em>

Graph the line with a slope of −1 that contains the point (3,6).
aksik [14]

Answer:

The equation of the line is y = -1.x + 9

Graph is provided in the attached figure

Step-by-step explanation:

The slope intercept equation of a line in 2D(x,y) coordinates is given by the equation

y = mx + c

where m is the slope of the line and c the y-intercept i.e. where the line crosses the y axis at x = 0

Given slope = -1, we can find c and the equation of the line

Since (3,6) is a point on the graph, these coordinates must satisfy the above equation

Substitute for y = 6 and x = 3

6 = (-1)3 + c\\\\c = 9\\\\\textrm{Equation of line is }\\y = -1.x + 9 \\y = 9-x

In the attached figure you can see that (3,6) is on the line
