Write an equation of the line in slope intercept form.
Answer:
y=[tex]\frac{-1}{2}[/tex]x+1
Step-by-step explanation:
First, let's do the easiest part, finding the y-intercept, which shows up at the end of your slope intercept equation, y=mx+b, where slope is rise over run!
- Simply look for where the coordinate is on the y-intercept, which is at y = 1!
Then, we need to find our rise over run, which is basically counting from point a to point b. To get to the lower coordinate from the top, we go down two (-2), and over 4. Which means we "rose" -2, and "ran" 4! It's -2 because we went DOWN, and positive 4 because we went FORWARD. This gave us 2 over 4, which is the same as 1 over 2!

write an equation and solve round to the nearest hundredth where necessary. 21 is 35% of what number
Answer:
21 is 35% of 60.
35% * x = 21
Multiply both side by 100 and divide both sides by 35.
x = 21 * 100/35
21 * 100 = 2100
2100/35 = 60.

Step-by-step explanation:
A locker combination has three nonzero digits, and the digits cannot be repeated. The first two digits are 1 and 2. What is the probability that the third digit is 3?
Answer:
Approximately 14% or 1/7
Step-by-step explanation:
To solve this problem, first find the ratio of 3 to the possible numbers.
There are 9 possible digits in one space on a non-zero combination lock. However, digits cannot be repeated, and 1 and 2 are already taken. Therefore, there are 7 possible digits (9 - 2 = 7). Therefore, the ratio of getting a 3 to possible digits is 1:7, as there is 1 '3' and 7 others.
As a fraction, 1:7 is 1/7. As a percentage, 1/7 is about 14%. Therefore, there is approximately a 14% chance that the third digit will be 3.
What is the equation of the line in the slope intercept form
Answer:
Equation of line; y = - 6x
Step-by-step explanation:
As we can see from this graph, point ( 0, 0 ) lying on this graph intersects the y - axis such that it forms a y - intercept of 0;
At the same time we can note that the change in y / change in x, in other words the slope, differs by a rise of 6 / run of - 1, 6 / - 1 being a slope of - 6;
If this equation is in slope - intercept form ⇒
y = a * x + b, where a ⇒ slope, and b ⇒ y - intercept,
Equation of line; y = - 6x
Answer:
y = -6x
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
the y intercept is 0 since it crosses the y axis at 0
To find the slope we need to points (0,0) and (10,-60)
m = (y2-y1)/(x2-x1)
= (-60-0)/(10-0)
= -60/10
= -6
The equation for the line is
y = -6x +0
y = -6x
if 3 kg of flour needs 4 1/2 cups of sugar how much is 4 kg Of flour
Answer:
This is the formula of how to answer this question hopefully it helps :)
Sugar = Flour
A cup of sugar weighs about 7 ounces, and a cup of all-purpose flour weighs about 4-1/2 ounces. So, if we're building a recipe with 1 cup sugar, we'll need about 1-1/2 cups flour (about 6-3/4 ounces).

suppose a 3-digit number is to be formed using the digits 1,2,3,4,5. How many different numbers can be formed. (digits can be repeated)
Answer:
125
Step-by-step explanation:
For the first digit of our number, we have 5 options (1, 2, 3, 4, 5). For the second and third digits, we still have 5 options because the digits can be repeated. This means that the total different numbers we can make is 5 * 5 * 5 = 125 numbers. Hope this helps!
Ben is buying a book that costs $14.75 and a magazine that costs $5.25. If he has a store cupón for 15% off and sale tax is 8%, how much will he pay in total?
Answer:
$18.36
Step-by-step explanation:
14.75+5.25=20
20 x 0.15 = 3
20 - 3 = 17
17 x 0.08=1.36
17+ 1.36 =18.36
total is $18.36

The measure of GI is 80 degrees. What is the measure of
Answer:
∠ GHI = 40°
Step-by-step explanation:
The inscribed angle GHI is half the measure of the intercepted arc GI, thus
∠ GHI = 0.5 × 80° = 40°
The measure of the ∠GHI is 40°.
What is an Inscribed Angle?An inscribed angle is the angle that an arc at any point on the circle subtends.
From the Inscribed angle theorem:
A circle's inscribed angle is half of the central angle that subtends the same arc on the circle, according to the inscribed angle theorem.
That means,
The measure of the ∠GHI
= the measure of the arc GI /2
= 80°/2
The measure of the ∠GHI = 40°
Therefore, the measure of center angle is 40°.

Round the number 5,370,288 to the nearest 100,000
Answer: 5,400,000
Step-by-step explanation:

5,400,000 is the final answer.
Step-by-step explanation:
5,370,288

Answer:
I think the answer would be B
Step-by-step explanation:
solve the diagram below to write an equation and solve for x.
Answer: The equation is (3x) + (2x + 20) + (x+10) = 180, and the x = 25.
Step-by-step explanation:
First, you know that all the measures of angles equal 180°.
So, we can make this equation:
(3x) + (2x + 20) + (x+ 10) = 180
Then, solve for x:
3x + 2x + 20 + x + 10 = 180
Combine the like terms that have the variable, x, in them:
6x + 20 + 10 = 180
Now combine the constant numbers:
6x + 30 = 180
Next, subtract 30 from that side:
6x = 180 - 30
6x = 150
Then, divide:
[tex]\frac{6x}{6}[/tex]= [tex]\frac{150}{6}[/tex]
x = 25
Therefore, the equation is (3x) + (2x + 20) + (x +10) = 180, and the x is 25.
Hope this helps! :)
Answer:
x = 25°
Step-by-step explanation:
Hello!
The sum of angles in a triangle is equal to 180°. If we add all the measures and set it to 180°, we can solve for x.
Solve for x3x + 2x + 20 + x + 10 = 1806x + 30 = 1806x = 150x = 25The value of x is 25°.
