Answer: f (-1) = 9
Step-by-step explanation:
You just have to substitute -1 for x
f (-1) = -3 (-1)^2 + 2 (-1) - 5
f (-1) = 3^2 + -2 - 5
f (-1) = 9 - 7
f (-1) = 2
I think I'm correct so I hope this helped!
[tex]f(-1)=-3.(-1)^{2} +2.(-1)-5\\=\\-3.1+(-2)-5\\-3+(-2)-5\\-5-5=-10[/tex]
p=1/2 q=-1/4 r=1/6 evaluate this: 48pqr(p+q+r)/(p+q)(p+r)
Answer:
-2
Step-by-step explanation:
48pqr x (p + q + r) / (p + q) x (p + r)
48(1/2)(-1/4)(1/6) x (1/2 + (-1/4) + 1/6) / (1/2 + (-1/4)) x (1/2 + 1/6) dear lord..
48(1/2)(-1/4)(1/6) x (0.4) / (0.25) x (0.7)
-1 x (0.4) / (0.25) x (0.7)
-0.4 / 0.2
= -2

rearrange equations to form y=mx+b
-2x+4=2y
-x+2=y
-y=-2x-5
y=2x+5
use these equations to find slope and y intercepts, and match those with the right graph
slope of first: -1
slope of second: 2
y-int of first: 2
y-int of second:5
An art teacher has a total of 5/8 pound of clay.The teacher puts 1/32 pound of clay at each work station.How many total work station will the art teacher be able to set up
Answer: Total work stations = 20
Step-by-step explanation:
Total clay = [tex]\dfrac58[/tex] pound
Clay at each work station = [tex]\dfrac1{32}[/tex] pound
Total work stations = (Total clay ) ÷ (Clay at each work station )
[tex]=\dfrac58\div\dfrac{1}{32}\\\\=\dfrac58\times32\\\\= 5\times4\\\\= 20[/tex]
Hence, Total work stations = 20

Write your answer using only positive exponents. Evaluate any numerical powers
36/w^6 is the correct answer
The simplified form of the given expression is -1/w¹.
What is a positive exponent?A positive exponent tells us how many times to multiply a base number, and a negate
ve exponent tells us how many times to divide a base number. We can rewrite negative exponents like x⁻ⁿ as 1 / xⁿ.
The given expression is [tex](-w^{\frac{3}{6} })^{-2}[/tex]

b/c this is an isosceles triangle we know that either leg is the same length.. so we can use many trig functions :)
SOH CAH TOA to remember how trig functions fit on the triangle...
we know the hypotenuse and the angle and we want to find the adjacent leg ( which for this triangle is also the opposite leg )
use Cos = Adj / Hyp
Hyp*Cos(45) = adj
16* [tex]\sqrt{2}/2[/tex] = adj
8*[tex]\sqrt{2}[/tex] = adj
each leg is the same [tex]8\sqrt{2}[/tex]
An Avon sales lady buys a make-up kit for $120 and sells it for $65 more. What is the percent of markup? 37.5%
Answer: 54.2%

In this case, the woman bought it for $120 and sold it for $65 more.
Cost = $120
Markup = $65
Markup percentage = 65 / 120 * 100%
= 54.2%
