ii. Tyler made no mistake.
<em>Algebraic expressions</em> include both <u>alphabet</u> and <u>number</u> so that the <em>value</em> of the <u>alphabet</u> is to be determined. The <u>value</u> of the <u>alphabet</u> in the <em>expression</em> would be determined by applying <em>mathematical operations</em> appropriately.
To solve the <u>question</u> given to Tyler, we have:
= -5
<u>square</u> both <em>sides</em> of the equation to have;
(x + 3) = 
x + 3 = 25
collect <em>like terms</em> to get;
x = 25 - 3
= 22
x = 22
1. Thus the equation is true if x = 22.
2. <u>Tyler</u> did not make any <u>mistake</u> in solving for x.

Answer:
292.5 miles per day
Step-by-step explanation:
The map shows it is 1170 miles from my school to Wall, South Dakota, a place well-advertised in the Midwest. If I want to take 4 days to get there, the required division is ...
... (1170 mi)/(4 da) = 292.5 mi/da
Answer:
B.
Step-by-step explanation:
factored form actually contains the x intercepts right in it. Basically whatever sets the whole equation equal to zero.
On the graph you can see that it passes through both positive and negative 4. so (x+4)(x-4) is the answer because plugging in 4 for x will make it zero. Same for plugging in negative 4
Hope this helps!
Answer:
.
Step-by-step explanation:
Start by finding the slope of the line perpendicular to
.
The slope of
is
.
In a plane, if two lines are perpendicular to one another, the product of their slopes would be
.
Let
denote the slope of the line perpendicular to
. The expression
would denote the product of the slopes of these two lines.
Since these two lines are perpendicular to one another,
. Solve for
:
.
The
is a point on the requested line. (That is,
and
.) The slope of that line is found to be
. The equation of that line in the point-slope form would be:
.
Rewrite this point-slope form equation into the slope-intercept form:
.
