What is the slope of the line that passes through the points (0, -4)) and (-2, -1)
Answer:
Step-by-step explanation:
y = mx + b
m is the slope (what you want)
b is the y-intercept, which is the value of y when x = 0
Oh, right, we already have b, isn't that great!
Given point (0, -4), so b = -4
Point (-2, -1), where x = -2 and y = -1
-1 = -2m -4 (solve for m)
3 = -2m
m = -3/2
Check:
y = -3x/2 -4
y = -3(-2)/2 -4 -> should get y = -1
y = 3 -4 = -1
Yay, we have the answer!
Yall plzz helpp I dont want to fail math "what is the longest walking stick that can be placed in the bottom of a truck of length 80 cm and width 60cm"
Given:
Length of the truck = 80 cm
Width of the truck = 60 cm
To find:
The longest walking stick that can be placed in the bottom of a truck.
Solution:
The longest walking stick that can be placed in the bottom of a truck is the diagonal of the truck.
We know that, the diagonal of a rectangle is:
[tex]d=\sqrt{l^2+w^2}[/tex]
Where, l is the length and w is the width.
Putting [tex]l=80[/tex] and [tex]w=60[/tex], we get
[tex]d=\sqrt{(80)^2+(60)^2}[/tex]
[tex]d=\sqrt{6400+3600}[/tex]
[tex]d=\sqrt{10000}[/tex]
[tex]d=100[/tex]
Therefore, the length of the longest walking stick that can be placed in the bottom of a truck is 100 cm.
Solve this trinomial
Z^2 + z = -20
Answer:
your answer is a complex number making your question wrong
Step-by-step explanation:
First z²+z+20=0, just to make it a quadratic equation, so we can use the quadratric formula:
x=( -b±√b²-4ac)/2a
so to find a b and c we compare
YOUR QUESTION SHOULD BE Z² +Z-20=O.
The approximate areas of two states are listed below.
Texas: 2.69×10^5 square miles
Rhode Island: 1.21×10^3 square miles
Determine the difference, in square miles, between the area of Texas and the area of Rhode Island. Write your answer in scientific notation.
Answer: _________________ square miles
Answer:
2.6779*10^5
Step-by-step explanation:
2.69 * 10^5 - 1.21 * 10^3
This is 2.6779*10^5 :)
The difference between the areas of Texas and the area of Rhode Island is given by equation A = 2.6779 x 10⁵ miles²
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the area of Texas be p = 2.69 x 10⁵ miles²
Let the area of Rhode Island be q = 1.21 x 10³ miles
Now , the difference of areas A = p - q
On simplifying the equation , we get
The difference between the area of Texas and the area of Rhode Island A = 2.69 x 10⁵ miles² - 1.21 x 10³ miles
A = 2.69 x 10⁵ miles² - 1.21 x 10³ miles
A = 10³ ( 2.69 x 100 - 1.21 )
On further simplification , we get
A = 10³ ( 269 - 1.21 )
A = 267.79 x 10³
A = 2.6779 x 10⁵ miles²
Hence , the difference in areas is 2.6779 x 10⁵ miles²

cent when calculating.)
Part B: Sales tax for all 3 retailers is 7.5%. What is the cost to purchase the cheapest coffeepot? (Round your answer to the nearest cent.)
Answer:
American Discounters is the cheapest.
Step-by-step explanation:
American Discounters:
149.49 - 30%
149.49 - (149.49 * 0.3) = 44.847
149.49 - 44.847 = 104.643
The Coffee Hut:
91.99 + 15%

A student worked out the following problem: Solve: 8x + 10 – 6x + 4 = 24 Step 1: 2x + 14 = 24 Step 2: 2x = 38 Step 3: x = 19
A) There is an error in step 1
B) There is an error in step 2
C) There is an error in step 3
D) There is no error
Answer
b
Step-by-step explanation:
Answer:
B) There is an error in step 2.
Step-by-step explanation:
When solving 8x+10-6x+4=24, you have to first combine your like terms. These are 8x and -6x (giving you 2x) and 10 and 4 (giving you 14).
After combing your like terms, you now have the equation 2x+14=24.
You need to get x alone and the first step to do that is to subtract 14 from both sides of the equation. This cancels out 14 from the side with x on it and leaves you with 10 on the other side. Your equation is now 2x=10
This is where the student made the mistake. Instead of subtracting 14, they added 14.
The final step would be to divide by 2 on both sides.
At the end of the problem, you are left with x=5.
