What are the zeros of the function below? F(x)=(x-2)(x+5)/(x+3)(x-1) PLEASE HELP!!!
Answer:
x = 2 & −5
Step-by-step explanation:
The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for x.
Rosa is putting carpet in her rectangular bedroom. She made a scale drawing using the scale 1 in = 3 ft. In the drawing the length is 5.5 in and the width is 3.25 inches. If the carpet is $2.58 per square foot, how much will it cost to carpet the bedroom?
Answer:
Total cost of carpet = $415 (Approx)
Step-by-step explanation:
Given:
Scale = 1 in = 3 ft
Length = 5.5 in
Width = 3.25 in
Carpet cost = $2.58 square foot
Find:
Total cost of carpet
Computation:
Actual Length = 5.5 x 3 = 16.5 ft
Actual Width = 3.25 x 3 =9.75 ft
Area = 16.5 x 9.75 = 160.875
Total cost of carpet = 2.58 x 160.875
Total cost of carpet = $415.0575
Total cost of carpet = $415 (Approx)

Find the distance between the points (2, -5) and (-6, -11)
Answer:
Step-by-step explanation:
(2, -5) ; (-6 , -11)
Distance = [tex]\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
[tex]=\sqrt{(-6-2)^{2}+(-11-[-5])^{2}}\\\\=\sqrt{(-6-2)^{2}+(-11+5)^{2}}\\\\=\sqrt{(-8)^{2}+(-6)^{2}}\\\\=\sqrt{64+36}\\\\=\sqrt{100}\\\\=10[/tex]

Describe and correct the error in finding the solution.
-4.2x=21
-4.2x/4.2=21/4.2 x=5
Answer:
The error is that the person divided both sides by positive 4.2 rather than negative 4.2. Here's how to correct it:
-4.2x ÷ -4.2 = x, 21 ÷ -4.2 = -5So, x = -5.I hope this helps!

The cost of renting a car is $ 30 /week plus $ 0.25 /mi travelled during that week. An equation to represent the cost would be y = 30 + 0.25 x , where x is the number of miles. What is your cost if you travel 35 miles? $ If you were charged $ 42.50 , how many miles did you travel? miles Get Help: VIDEO LicensePoints possible: 1
Answer:
Amount charged for 35 miles is $ 38.75
If amount charged is $ 42.50 then distance travelled is 50 miles
Step-by-step explanation:
Equation that represents the cost is [tex]y=30+0.25x[/tex]
Here,
x denotes the number of miles
$ 30 is the amount of rent per week
$ 0.25 is amount charged for 1 mi
To find cost if distance travelled is 35 miles, put [tex]x=35[/tex] in [tex]y=30+0.25x[/tex]
Cost (y) = [tex]30+0.25(35)=\$38.75[/tex]
So,
Amount charged for 35 miles is $ 38.75
To find number of miles for which amount charged is $ 42.50, put [tex]y=42.50[/tex] in [tex]y=30+0.25x[/tex]
[tex]42.50=30+0.25x\\42.50-30=0.25x\\12.5=0.25x\\x=\frac{12.5}{0.25} \\x=50[/tex]
So,
if amount charged is $ 42.50 then distance travelled is 50 miles.
Explain how you would graph the line containing a slope of-1/5 that goes through the point (1,-4)
Answer:
y= -1/5x + 1/5
Step-by-step explanation:
y- y1 = m(x - x1)
Slope m=-1/5
(1, -4)
1 = y1
-4 = x1
y- 1 = -1/5(x-(-4))
y-1 = -1/5(x+4)
y-1= -1/5(x)+ -1/5(4)
y-1 = -1/5x + -4/5
add one to both sides
y= -1/5x + -4/5 + 1
y = -1/5x + 1/5
