Answer:
Step-by-step explanation:
using Pemdas rule
here in this problem first multiply and then add
Answer:
Step-by-step explanation:
perimeter =76 m
L=3+w
w
2L+2W=76
2(3+W)+2W=76
6+2w+2w=76
4w=70
w=70/4
w=17.50
L=17.50+3=20.50
A=L*W=17.50*20.50=358.75m^2
1) These angles are actually equal so set the equation to…
58=5x-2
60=5x
X=12
2) These angles are also equal to each other
16x+22=134
16x=112
X=7
3) These angles are equal too
7x-1=125
7x=126
X=18
4) These angles are supplementary so they add to 180 degrees
9x+2+133=180
9x+135=180
9x=45
X=5
5) These angles are equal as well
8x-77=3x+38
5x-77=38
5x=115
X=23
6) These angles are also equal
11x-47=6x-2
5x-47=-2
5x=45
X=9
7) these also sum to 180
13x-21+5x+75=180
18x+54=180
18x=126
X=7
8) These angles add to 180 as well
9x-33+5x+3=180
14x-30=180
14x=210
X=15
In conclusion, just know how to solve simple one variable equation and know which angles are congruent and supplementary and this will be easy.
Average rate of change over interval [a,b]: r=[f(b)-f(a)]/(b-a)
In this case the interval is [0,2], then a=0, b=2
r=[f(2)-f(0)]/(2-0)
r=[f(2)-f(0)]/2
1) First function: h(x)
r=[h(2)-h(0)]/2
x=2→h(2)=(2)^2+2(2)-6
h(2)=4+4-6
h(2)=2
x=0→h(0)=(0)^2+2(0)-6
h(0)=0+0-6
h(0)=-6
r=[h(2)-h(0)]/2
r=[2-(-6)]/2
r=(2+6)/2
r=(8)/2
r=4
2) Second function: f(x)
A function, f, has an
x-intercept at (2,0)→x=2, f(2)=0
and a y-intercept at (0,-10)→x=0, f(0)=-10
r=[f(2)-f(0)]/2
r=[0-(-10)]/2
r=(0+10)/2
r=(10)/2
r=5
3) Third function: g(x)
r=[g(2)-g(0)]/2
From the graph:
g(2)=6
g(0)=2
r=(6-2)/2
r=(4)/2
r=2
4) Fourth function: j(x)
r=[j(2)-j(0)]/2
From the table:
x=2→j(2)=-8
x=0→j(0)=4
r=(-8-4)/2
r=(-12)/2
r=-6
Answer:
Pairs
1) h(x) 4
2) f(x) 5
3) g(x) 2
4) j(x) -6
That's a test! A hell no I'm not gonna help
