Answer:
Y= -x-4
(-1,-3)
Step-by-step explanation:
Simply plot the point (-5,1) and draw in a line with a slope of -1. Take the slope of this line and the point it crosses the y-axis and use them to set up slope intercept form.
Which expression can you substitute in the indicated equation to solve the system below 5x+y =8 x+4y=2
Answer:
x = 1.58 and y = 0.105
Step-by-step explanation:
Given equations are :
5x+y =8 ...(1)
x+4y=2 ...(2)
Multiply equation (2) by 5.
5x+20y=10 ..(3)
Subtract equation (1) from (3).
5x+20y-(5x+y) = 10-8
5x+20y-5x-y = 2
19y = 2
y = 0.105
Put the value of y in equation (2).
x+4(0.105)=2
x = 2-0.42
x = 1.58
Hence, the values of x and y are 1.58 and 0.105.

What is the number? I did many ways but i didn't found it, please guys help me with it.
Answer:
A). 15
B). -1.2
Step-by-step explanation:
A). [10(x+3)]-20 = 160
10x+30-20 = 160
10x+10 = 160
10x = 160-10
10x = 150
x = 150/10
x = 15
B). 5{[4(8+(5x))]-9} = 85
5(32+20x+9) = 85
5(32+9+20x) = 85
5(41+20x) = 85
205+100x = 85
100x = 85-205
100x = -120
100x/100 = -120/100
x = -1.2

The hypotenuse of a right triangle is 13 inches long. The shorter leg is 7 inches shorter than the longer leg. Find the side lengths of the triangle.
Answer:
5 and 12 inches
Step-by-step explanation:
Let the shorter leg be x.
13²=x²+(x+7)²
169=x²+x²+14x+49
169=2x²+14x+49
120=2x²+14x
120=2x(x+7)
60=x(x+7)
60=x²+7x
x=5
shorter length=5, longer length=12
9. The functions f and g are such that
f(x) = 3(x – 4) and g(x) = x/5+1
a) Find the value of f(10)
b) Find g-'(x)
c) Show that ff(x) = 9x - 48
Answer:
a) f(10) = 18
b) g-¹(x) = 5x-5
c) 3((3(x-4))
= 3((3x-12)-4))
= 3(3x-16)
= 9x-48
The value of f(10) = 18, g'(x) = 1/5 and ff(x) = 9x - 48
What is function?A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.
Given that, The functions f and g are such that f(x) = 3(x – 4) and
g(x) = x/5+1
a) f(10) = 3(10-4)
= 3(6)
= 18
b) g'(x) = d/dx(x/5+1)
= 1/5d/dx(x) = 1/5
c) ff(x) =
= 3((3(x-4))
= 3((3x-12)-4))
= 3(3x-16)
= 9x-48
Hence, The value of f(10) = 18, g'(x) = 1/5 and ff(x) = 9x - 48

Question 3 (1 point)
A cylinder has a radius of 13 feet and a
height of 28 feet. Which statement about
the cylinder is not true?
a
The circumference is about 82 ft.
The area of one base is about 531 ft2
ОООО
The lateral area is about 2,286 ft?
The total surface area is about 2,818 ft?
Question 4 (1 nointi
Step-by-step explanation:
The radius of a cylinder, r = 13 feet
Height of the cylinder, h = 28 feet
The circumference of the cylinder is given by :
[tex]C=2\pi r\\\\=2\pi \times 13\\\\=81.68\ ft\\\\C=82\ ft[/tex]
The area of one base is given by :
[tex]A=\pi r^2\\\\=\pi \times 13^2\\\\=530.92\ ft^2\\\\=531\ ft^2[/tex]
The lateral area of the cylinder is given by :
[tex]A=2\pi r h\\\\A=2\pi\times 13\times 28\\\\A=2287.07\ ft^2[/tex]
Total surface of the cylinder is given by :
[tex]A=2\pi r h+2\pi r^2\\\\=2287.07+2\pi \times (13)^2\\\\=3348.92\ ft^2[/tex]
The total surface area of the cylinder is not matched with the given data. Hence, option (4) is not correct.

the school store has1200 pendls in stock and sells and sells an average of 25 pencils per day the manager reorders when the number of pencils in stock in 650
Answer:
Number of pencils in stock = 1200
Average number of pencils sold by the manager per day = 24
Number of pencils that would be sold before reordering = 1200 - 500
= 700
Then
The number of days after which the manager will reorder = 700/24
= 29.16
So the manager has to reorder after about 30 days. Since the answer comes in fraction of more than 29 days, so it has to be 30 days. I hope the procedure is clear for your understanding.
Just to be clear, this answer is not mine, but I remember seeing this question so I just copied someones' answer. Still, you might find this helpful.
