3x + 2 = 17
Step 2: Solve for x
[Subtraction Property of Equality] Subtract 2 on both sides: 3x = 15[Division Property of Equality] Divide 3 on both sides: x = 5Answer:
you subtract two both side, then divide three both side, you'll get x = 5.
Step-by-step explanation:
3x + 2 = 17
(3x + 2) -2 = (17) -2. First, you subtract 2 for both sides
3x = 15
(3x)/2 = (15)/2. Second, you divide 3 both side
x = 5. Last, you get your answer

X - 6 = -24
Solve for x.
Answer:
x= -18
Step-by-step explanation:
x= -24 + 6
Add -24 and 6.
x= -18
Answer:
X = -18
Step-by-step explanation:
You want to isolate X by itself. To isolate X on one side of the = sign, use the addition property of equality (to undo the subtraction of 6 from x) by adding 6 to both sides of the equation. We use the addition property of equality because this is the inverse operation. It is important to add 6 to both sides of to maintain an equivalent equation.
1. Set up your equation
X - 6 = -24
+6 +6
2. Solve out
X - 6 = -24
+6 +6
X = -18
Answer: -18

Find the slope of a line passing through the given points.
(-4, 2) and (5,6)
slope =
Answer:
4/9
Step-by-step explanation:
To find slope without a graph, you subtract the 2 y-coords and the 2 x-coords, then divide the y-coord by the x-coord.
The formula is (y²-y¹)/(x²-x¹).
So we just plug in the coordinates.
(6-2)/(5-(-4))
(6-2)/(5+4)
4/9
So the slope is 4/9

Suppose that, as course instructor, you decide instead that you want to calculate a 95% confidence interval for the population proportion of all Cal Poly students who have ever marched in a Memorial Day Parade, and that you would like the margin of error of your 95% confidence interval to be .05, and that you would like to use a (most) conservative sample size for this task. What sample size should you use
Answer: 385
Step-by-step explanation:
If prior population proportion p is unknown, then the formula to compute sample size will be:
[tex]n= 0.25(\frac{z^*}{E})^2[/tex]
where, E= Margin of error, z* = Critical zvalue
Given: E= 0.05
Critical value for 95% confidence = 1.96
Required sample size: [tex]n=0.25(\frac{1.96}{0.05})^2[/tex]
[tex]\\=384.16\approx385[/tex]
Hence, the required sample size = 385

A rectangular garden 800 square feet in area is to be fenced off against rodents. Find the dimensions that will require the least amount of fencing if one side of the garden is already protected by a barn.
Step-by-step explanation:
the area of a rectangle is
a × b
with a, b being the length and width (in any sequence).
a×b = 800
a = 800/b
the perimeter is
2a + 2b
one side is not needed, so we take one of them off. e.g. we take off one a.
a + 2b need to be a minimum
800/b + 2b
f(b) = 800/b + 2b
the extreme value(s) we find as the zero points of the first derivative.
f'(x) = -800/(b²) + 2 = 0
2 = 800/(b²)
2b² = 800
b² = 400
b = ±20 ft
negative lengths don't make sense, so, 20 ft is the solution.
a×b = 800
a×20 = 800
a = 40 ft
so, the minimum fencing is for
a = 40 ft
b = 20 ft (2 times)
the second a is covered by the barn.

A teacher has a box of 88 colored pencils. He gave 46 away. The teacher put the rest of the colored pencils into 7 equal groups
How many colored pencils are in each group?
Answer:
6 pencils in each group
Step-by-step explanation:
Total = 88
Gave away = 46
Balance = 88 - 46 = 42
Divided into 7 groups, means : 42/7 = 6
So each group has 6 pencils

The bisector goes through photosynthesis causing the qordinates of the triangle to find the spectrum
(-2,-3) (-1,2) write the equation in y=mx+b
Answer:
y = 5x + 7
Step-by-step explanation:
(-2, -3) & (-1, 2)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(2 - (-3)) / (-1 - (-2))
Simplify the parentheses.
= (2 + 3) / (-1 + 2)
= (5) / (1)
Simplify the fraction.
5/1
= 5
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 5x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (-1, 2). Plug in the x and y values into the x and y of the standard equation.
2 = 5(-1) + b
To find b, multiply the slope and the input of x(-1)
2 = -5 + b
Now, add 5 to both sides to isolate b.
7 = b
Plug this into your standard equation.
y = 5x + 7
This is your equation.
Check this by plugging in the other point you have not checked yet (-2, -3).
y = 5x + 7
-3 = 5(-2) + 7
-3 = -10 + 7
-3 = -3
Your equation is correct.
Hope this helps!

Tom has a 490-page book to read. If he has already read 56 pages, how many more pages should he read each week
o finish in 6 weeks?
Write an equation for the situation and then answer the question.
If he has read 56 pages and there are a total of 490, then how many are left? That's 490 - 56 = 434.
To read 434 pages in 6 weeks, he should read 434 / 6 pages each week. That's 72 1/3 pages per week.
