Answer:
k = 1/2
Step-by-step explanation:
g(x) = 3 - kx g^-1(4) = -2
y = 3 - kx
x = 3 - ky
x - 3 = -ky
(x-3) / (-k) = y
(x-3) / (-k) = (g^-1(x))
4-3 / (-k) = -2
1 / (-k) = -2
1/k = 2
1 = 2k
1/2 = k

Solve the following system of equations.
x-3y=17
x+7y=-23
x=
y=
Answer:
-4y=40
y=-10
x-3(-10)=17
x-30=17
x=17+30
x=47
Step-by-step explanation:
Answer:
x= 5
y= -4
Step-by-step explanation:
x= 17+3y so you substitute what you got for x in so
17 +3y +7y = -23
10y=-40
y=-4 now you put -4 in for y in the first equation
x = 17 + (3 times -4)
x = 17 - 12
x=5
Carlos has 38 apples. He puts 8 apples into each bag. If he fills as many bags as possible, How many apples are left
A .6

The equation y=9.50 +0.4 represents the line of best fit for the distance in feet) that Marcella traveled over time
(in seconds) based on several races she ran.
Based on this equation what is Marcella's average speed in feet per seconds?
Enter the answer as the correct value without units.
marking brainlist
Answer:
9.9 feet per second
Step-by-step explanation:
y=9.5+0.4
y=9.9
Marcella's average speed in feet per seconds is,
⇒ y = 9.54 feet
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The equation which represents the line of best fit for the distance in feet) that Marcella traveled over time (in seconds) based on several races she ran is,
⇒ y = 9.50x + 0.4
Hence, Marcella's average speed in feet per seconds is,
y = 9.50x + 0.4
Put x = 1;
y = 9.50 × 1 + 0.4
y = 9.50 + 0.4
y = 9.54 feet
Thus, Marcella's average speed in feet per seconds is,
⇒ y = 9.54 feet

Find the slope of the line with f(6) = -2 and f(-4) = 3
Answer:
m=-1/2
Step-by-step explanation:
f(6)=-2 is (6,-2) and f(-4)=3 is (-4,3)
the equation for slope (m) is (y2-y1)/(x2-x1)
label the points:
x1=6
y2=-2
x2=-4
y2=3
now substitute into the equation:
m=(3--2)/(-4-6)
m=5/-10
m=-1/2
the slope is -1/2

Answer:
area of trapezoid==1/2 h(d1+d2)=7.5/2(10+(5+2×3+5))=97.5in²
area of semi circle=1/2 πr²=1/2 ×3.14×3²=14.13in²
area of shaded region=97.5-14.13=83.37in²
Answer:
outside shape = (10x7.5)+(2)(0.5)(7.5x3) = 97.5 in^2
circular cutout = (3.14)(3^2)(0.5) = 14.1 in^2
97.5-14.1 = 83.4 in^2

x = {-0.44, 1.69}
Step-by-step explanation:
Multiply by the denominator to eliminate the fraction.
3 = x(4x -5)
4x^2 -5x -3 = 0 . . . . . subtract 3 and put in standard form
Using the quadratic formula with a=4, b=-5, c=-3, we have the solutions as ...
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-(-5)\pm\sqrt{(-5)^2-4(4)(-3)}}{2(4)}\\\\x=\dfrac{5\pm\sqrt{73}}{8}\approx \{-0.443, 1.693\}[/tex]
Solutions rounded to hundredths are ...

What is the equation of the line that passes through point (-1,4) and is perpendicular to the following equation? y= -1/2x - 4
Answer:
y=2x-4
Step-by-step explanation:
To find an equation perpendicular to another one, you must find the negative inverse of the slope.
In this case, -1/2 has an inverse of -2, but because we're finding the negative inverse, the two negatives cancel out and we get 2, the slope of our perpendicular equation, which crosses the initial equation, making a right angle.
