Answer:
7212.53, i belive
Step-by-step explanation:
56 x 6.33 = 354.48
91 x 2.85 = 259.35
259.35 + 354.48 = 613.83
1547.76 - 613.83 = 933.93
6278.60 + 933.93 = 7212.53
if f(x) = x^2, and
g(x) = x-1, then
g(f(x))=x^__+__
Answer:
(x^2) + (-1)
Step-by-step explanation:
the equation f(x) BECOMES x in the g(x)
x-1
(x^2) -1
Answer:
g(f(x)) = x^2 + (-1)
Step-by-step explanation:
f(x) = x^2
g(x) = x - 1
Therefore, for g(f(x)), we need to substitute the value of x in f(x) in g(x).
Therefore,
g(x) = (x^2) - 1
= (x^2) + (-1)

GEOMETRY: need some help on these equations, i'm giving a lot of points for this.
Answer:
1) ML=93
2) GE=58
Step-by-step explanation:
1)
We want to find ML.
So, we need to find x first.
Note that the entire segment, NK, is the addition of the segments NM, ML, and LK. So:
[tex]NM+ML+LK=NK[/tex]
And we know their equations. So, substitute 110+4x for NM, x+103 for ML, 70 for LK, and x+243 for NK. Thus:
[tex](110+4x)+(x+103)+(70)=x+243[/tex]
On the left, combine like terms:
[tex](4x+x)+(110+103+70)=x+243[/tex]
Add:
[tex]5x+283=x+243[/tex]
Subtract 283 from both sides:
[tex]5x=x-40[/tex]
Subtract x from both sides:
[tex]4x=-40[/tex]
Divide both sides by 4:
[tex]x=-10[/tex]
So, the value of x is -10.
Substitute this into ML to find it. So:
[tex]ML=(-10)+103[/tex]
Add:
[tex]ML=93[/tex]
And we're done!
2)
Here, we want to find GE. This means solving for x again.
Note that HF plus FE equates to the entire segment.
HG plus GE also equates to the entire segment.
Thus:
[tex]HF+FE=HG+GE[/tex]
Substitute 3x-129 for HF and 4 for FE.
Substitute 13x-993 for HG and 3x-185 for GE. Thus:
[tex](3x-129)+(4)=(13x-993)+(3x-185)[/tex]
Combine like terms on both sides:
[tex](3x)+(-129+4)=(13x+3x)+(-993-185)[/tex]
Add or subtract:
[tex]3x-125=16x-1178[/tex]
Add 1178 to both sides:
[tex]3x+1053=16x[/tex]
Subtract 3x from both sides:
[tex]1053=13x[/tex]
Divide both sides by 13:
[tex]x=81[/tex]
So, the value of x is 81.
To find out GE, GE is the 3x-185. So:
[tex]GE=3(81)-185[/tex]
Multiply:
[tex]GE=243-185[/tex]
Subtract:
[tex]GE=58[/tex]
And we're finished!

Solve for x:
X- 6 = -3x + 22
Answer:
Your answer is x=7
Step-by-step explanation:
[tex]x - 6 = -3x + 22[/tex] add 6 to both sides
[tex]x - 6(+6) = -3x + 22(+6)[/tex] cross out -6(+6) and add 22+6=28
[tex]x = -3x + 28[/tex] add 3x on both sides
[tex]x (+3x) = (+3x)-3x + 28[/tex] x+3x=4x and cross out (+3x)-3x
[tex]4x = 28[/tex] divide 4 on both sides
[tex]\frac{4x}{4} = \frac{28}{4}[/tex] cross out 4 leave x and divide 28 and 4 =7
[tex]x=7[/tex]
Answer:
x=7

divide both side by 8
y=0
solve for X in equation 1
4(X)-9(0)=28
4x-0=28
4x =28
divide both side by 4
4x/4=28/4
X= 7

what is the slope of the line that passes through the points (5,10) and (11,-12)
Answer:m=-11/3
Step-by-step explanation:
Answer:
-11/3
Step-by-step explanation:
We have two points so we can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( -12-10)/(11 -5)
= -22/6
= -11/3

The measure of G is six more than twice the measure of H. If G and H are supplementary angles, find the measure of H pls I need help pls
Answer:
G=2H+6. -(1)
Also, G and H are supplementary angles which mean their sum would be180.
G+H=180
G=180-H. -(2)
From (1)&(2)
2H+6=180-H
3H=174

1. A point is named or labeled using? 2. Three distinct points are collinear if ? 3. Three distinct points are coplanar if ? PLZ HELP
Answer:
1) A point P is named or labeled by using a coordinate pair, where the regular notation is:
P = (x, y).
Where x and y are the horizontal and vertical components.
2) Three distinct points are collinear if exists a line that passes through the 3 points.
3) Three distinct points are complanar if they are not collinear, this means that:
We can have two colinear points (so one line connects them) and another point outside that line.
Then the set of 3 points is coplanar.
