Answer:
7.5
Step-by-step explanation:
draw the triangles separately then write a fraction for the small one x/6 and 10/8 then to get rid of the 6 to get x by itself you multiply by 6 to get X and for the other side you do 10/8 then multiply 1.25 times 6 to get 7.5
please add a thanks and a brainliest
hope this helped
Answer:
Step-by-step explanation:
Four
Start by trying to understand what f(x) means. First of all it is the same thing as y in the equation given in question 4. It is a shorthand that tells you that you put an x in wherever you see an x on the right.
More important, it tells you what to put in for x on the right.
f(z) would tell you to put z in for x anywhere there is an x on the right.
f(z)=2z+1. It is just a shorthand to tell you what to do on the right.
f(2) means put a 2 in for the x on the right. Read all of this carefully. You need to know it.
f(2) = 2(2) + 1
f(2) = 4 + 1
f(2) = 5
=================
Five
f(x) = -x - 5 The minus 4 is not going to change what you do.
f(-4) = -(-4) - 5 Wherever you see an x you put in a minus 4
f(-4) = 4 - 5
f(-4) = - 1
======================
Just so you know, consider a more complicated example
f(x) = 20x^3 + 7x^2 + 4x + 19
Where ever you see an x put in 2
f(2) = 20*(2^3) + 7*(2^2) + 4(2) + 19
f(2) = 20*8 + 7*4 + 4*2 + 19
f(2) = 160 + 28 + 8 + 19
f(2) = 215
Note x can be anything the question tells you it is.
f(5) means put a 5 in for every x.
Answer:
Carla pays $21.4 for the dress with tax.
Step-by-step explanation:
Here we are given that :
Price of dress = $20
Sales tax = 7%
Price of dress with tax = $20 + 7% of 20
Price of dress with tax = 20+1.4 = 21.4
Price of dress with tax = $21.4
Carla pays $21.4 for the dress with tax.
Answer:6908 (miles) ^2
Step-by-step explanation:
diameter=2200 miles
π=3.14
Circumference=π x diameter
Circumference=3.14 x 2200
Circumference=6908 (miles)^2
