3 4. What is the slope of the line that passes through (-2, 1) and (8,5)?
Answer: 2/5
Explanation: Ask if you want an explanation!
The question gives us two points, (-2, 1) and (8,5), from which we can find the slope and later the equation of the line.
Finding the Slope
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (5 - 1) ÷ (8 - (-2))
= ⁴/₁₀
= ²/₅
Checking my answer:
We can check to see if the answer is correct by drawing the line and seeing if it passes through both points. If it does, then the slope is correct.
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - 1 = ²/₅ (x + 2)
In the graph below (created using Desmos), the line passes through both points. This suggests that we calculated the slope correctly.

The cost of $ 385 in 2004 was 10% more than the cost in2003. Calculate the cost in 2003.
9514 1404 393
Answer:
$350
Step-by-step explanation:
Let c represent the cost in 2003. Then we have the cost in 2004 is ...
c + 0.10·c = 385
1.1c = 385
c = 385/1.1 = 350
The cost in 2003 was $350.
Given (x – 7)2 = 36, select the values of x.

Using a set of numbers find the mean round to the nearest tenth median mode and range 8,6,3,7,1,6,5,6
Answer:
Mean 5.3, Median 6, Mode 6, Range 7
Step-by-step explanation:
First we arrange the numbers from smallest to the largest. (When you are done count them to see if you have the same amount of numbers that you had before you arrange them.)
1, 3, 5, 6, 6, 6, 7, 8
Mean: is the average of all the numbers :add all numbers / how many numbers we have
(1+ 3+ 5+ 6+ 6+ 6+ 7+ 8) /8 = 42/8 = 5.25 ≈5.3 (rounded to the nearest tenth)
Median: is average of the 2 numbers that are in the middle 1, 3, 5, 6, 6, 6, 7, 8
(6+6)/2 = 6
Mode: is the number that appears the most so is 6
1, 3, 5, 6, 6, 6, 7, 8
Range: is the difference between the highest and the lowest value
1, 3, 5, 6, 6, 6, 7, 8
8-1 = 7
Answer:
Mean- 42
Median- 6
Mode- 6
Range- 7

Preliminary:
Fractions in Mathematics are rational numbers that can be written in the form x/y, where x and y are integers, and y 0 and the number x is not a multiple of y. In fractions x is called the numerator while y is called the denominator.
Fraction Types:
Common Fraction = is a fraction expressed in the form x/y, x as the numerator and y as the denominator. x and y are integers and y 0Mixed fraction = is a combination of whole numbers and fractions, expressed in the form a [tex] \frac{b}{c} [/tex]Decimal fractions are indicated by a comma (,) as a separator between the round and fractional parts. The round part is in front of the comma and the fraction part is behind it. One digit after the comma means the denominator of the fraction 10, two digits after the comma means the denominator of the fraction 100, and so on.A percent fraction is a fraction that has a denominator of 100, expressed in the form a%. example 50% is the same as [tex] \frac{50}{100} [/tex]Answer:
[tex] \frac{1}{2} [/tex]
Step-by-step explanation:
[tex]3( \frac{6}{8} - \frac{1}{2} ) + 0.25 = \frac{3 \times 2}{4 \times 2} - \frac{1}{2} = \frac{3 - 2 \times 1}{4} = \frac{1}{4} + 0.25 = \frac{50}{100} = \frac{1 \times 50}{2 \times 50} = \frac{1}{2} [/tex]

Given m∠14+m∠3=180° .
Which lines are parallel, if any must be parallel, based on the given information?
a∥b by the converse of the same-side interior angles theorem.
c∥d by the converse of the corresponding angles theorem.
Not enough information to make a conclusion.
a∥b by the converse of the alternate interior angles theorem.
description of picture : Two nearly horizontal lines, line c and line d, where line c is above line d. These lines are intersected by two diagonal lines, line a and line b. Line a is to the left of line b. The angles created by each intersection are numbered. From top left, going clockwise, the angles where line a intersects line c are labeled eleven, ten, nine, and twelve. The angles where line b intersects line c are labeled seven, six, five, and eight. The angles where line a intersects line d are labeled fifteen, fourteen, thirteen and sixteen. The angles where line b intersects line d are labeled three, two, one and four.
Answer:
c∥d by the converse of the corresponding angles theorem.

A line passes through the points (0, 9) and (9, 19). What is its equation in slope-intercept form?
Answer:
y = 10/9x + 9
Step-by-step explanation:
To write the equation in its slope-intercept form, y = mx + b, we need to find the slope (m) of the line and its y-intercept (b).
Given the points (0, 9) and (9, 19), we can solve for the slope of the line using the following formula:
[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]
Let (x1, y1) = (0, 9)
and (x2, y2) = (9, 19)
Substitute these values on the formula:
[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{19 - 9}{9 - 0} = \frac{10}{9}[/tex]
Therefore, the slope (m ) = 10/9.
Next, the y-intercept is the point on the graph where it crosses the y-axis, and has the coordinates, (0, b ). It is also the value of the y when x = 0.
One of the given points is the y-intercept of the line, given by (0, 9). The y-coordinate, 9, is the value of b.
Therefore, the linear equation in slope-intercept form is: y = 10/9x + 9
i know its easy but i forgot how to do this pls heeeelp me
Answer:
First number line: 3rd line from 0
Second number line: 7th line from 0
(Sorry if I explained it kinda weird, hope this helps!)
Step-by-step explanation:
On the first number line, you would put the dot on the 3rd line from zero. From 0 to one, it's split into 5 equal parts. 0 is 0/5 and 1 is 5/5. So all you do is plot the dot on 3/5, or the 3rd line from 0.
Same thing with the second number line. Except for this time, it's split into 8 equal parts. Just count to the 7th line in between 0 and 1 and plot the dot.
please write the answers with explanation..if nonsense answers I will report.....so answer properly
Answer: 86 degree
Step-by-step explanation:
The Straight line is 180 degrees so if we minus 180 by the outward degree there will be the degree for inward degree
P: 95 degrees T: 160 degree S: 88 degrees R: 91 degree
The degree for the pentagon is 540 degrees so If I minus 540 by all the four inward degrees there will be the missing last degree
95 + 160 + 88 + 91 = 434 degree
540 - 434 = 106 degree
180 - 106 = 94 degree
So the last inward degree is 94
Finally, if I minus 180 by 94 (the way I used to find inward degree and to find outward degree for now) it equals 86 degree
so X is 86 degree
Sorry if this was too confusing:)
Answer:
1st--> x=135
2nd-->x=74
Step-by-step explanation:
1st:
triangle =180°
180-90=90
90÷2=45
straight line=180°
180-45=135
therefore x=135°
2nd:
pentagon=540°
straight line=180°
180-92=88 for line s
180-20=160 for line q
180-85=95 for line p
180-89=91 for line r
160+95+88+91=434
540-434=106
180-106=74
therefore x=74°
hope that's okay

what is the percent change from 450 to 117
Answer:
Change ≈ 284.6154%
Step-by-step explanation:
To calculate the percent change of two numbers such as 450 to 117, you use the Percent Change Formula, where a is the start value and b is the end value.
(b-a)/a x 100
When we insert a = 450 and b = 117 in the formula above, then we get the following that we can simplify and solve to get the percent change from 450 to 117.
(117-45)/450 x 100
-333/450 x 100
Change = -74%
Now you know that the percentage change from 450 to 117 is -74%. Since it is a negative answer, it means that if you subtract 74% from 450, then you will get 117.

Given the explicit rule, F(n) = 250 + 130(n-1), what is the 12th term?
Of(12)=-$1180
Of(12)= $1810
O f(12)= $1680
Of(12)=-$1050
Answer:
f(12) = 1680
Step-by-step explanation:
Substitute n = 12 into f(n) , that is
f(12) = 250 + 130(12 - 1) = 250 + 130(11) = 250 + 1430 = 1680

Answer:
x=20
Step-by-step explanation:
add 5 to both sides
x/20=-4+5
simplify -4+5 to

The Ferrari Testarossa and the Porsche 911 Turbo are 400 miles apart and headed straight toward each other. The Ferrari is going 120mph, and the porsche is going 130 mph. How many hours will it take for the accident to occur?
Answer:
1.6 hours
Step by step explanation;
1 hour would make them only 150 miles apart, 60% of 120 and 60% of 130 added together is 150 mph, so 1.6 hours
