Answer:
Step-by-step explanation:
If it's parallel, that means it has the same slope: -1/5.
Use point-slope form to write the equation:
y - 4 = -1/5 (x - 7)
If you wish to write in point-intercept form:
y - 4 = -1/5 x + 7/5
y = -1/5 x + 27/5
If two lines are parallel, it means that they will have the same gradient:
And remember, the equation of a line is y = mx +c
-----------------------------------
So we know that the equation of the parallel line is:
y = - [tex]\frac{1}{5}[/tex]x + c through point (7, 4)
All we need to do now is to work out what c is
Note: at point (7, 4) x = 7 , and y = 4.
So to work out c, we substitute in the values of x and y, and solve:
y = - [tex]\frac{1}{5}[/tex]x + c
4 = - [tex]\frac{1}{5}[/tex] * 7 + c
4 = -1.4 + c
5.4 = c
----------------------------------
Finally, we just put the value of c back into the original equation
y = - [tex]\frac{1}{5}[/tex]x + 5.4
------------------------------------------
Answer:
The equation of the a line parallel to y = - [tex]\frac{1}{5}[/tex]x + 3 through point (7,4)
is: y = - [tex]\frac{1}{5}[/tex]x + 5.4

What is the equation of the line graphed below?
Answer:
y = 3x - 2
Step-by-step explanation:
(1,1) and (2,4)
Slope = (4 - 1)/(2-1) = 3, y- intercept b = -2
Equation
y = 3x - 2
Answer:
Y = 3x - 2 will be the answer.
Step-by-step explanation:
A line has been graphed in the figure attached.
It passes through two points ( 1,1) and (2,4)
Y-intercept of the given line is (-2)
Since equation of a line in the intercept form is
y = mx + c
where m = slope and c = y-intercept
and slope m = [tex]\frac{y-y'}{x-x'}[/tex]
Therefore, slope m = [tex]\frac{4-1}{2-1}[/tex]

Therefore, equation of the given line will be y = 3x - 2
In right triangle PQR, if sinP=5/13, then tanP=
5/12
12/13
12/5
Answer:
A
Step-by-step explanation:
Given sinP = [tex]\frac{5}{13}[/tex] = [tex]\frac{opposite}{hypotenuse}[/tex]
Then the right triangle has a hypotenuse of 13 and a leg 5
Use Pythagoras' identity to find the other leg x ( adjacent)
x² + 5² = 13²
x² + 25 = 169 ( subtract 25 from both sides )
x² = 144 ( take the square root of both sides )
x = [tex]\sqrt{144}[/tex] = 12 , hence
tanP = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{5}{12}[/tex]
The value of the tanP when sin is equal to 5/13 is 5/12.
We have given that,
[tex]sinP = \frac{5}{13}[/tex]
What is the formula for the sin ratio?[tex]sin(\theta)=\frac{Opposite}{hypogenous}[/tex]
Then the right triangle has a hypotenuse of 13 and a leg of 5
Use Pythagoras' identity to find the other leg x ( adjacent)
x² + 5² = 13²
x² + 25 = 169 ( subtract 25 from both sides )
x² = 144 ( take the square root of both sides )
taking square root on both sides
[tex]x=\sqrt{144} \\x=12[/tex]
Therefore we get the value of the tanP.
[tex]tanP = \frac{opposite }{adjucent} = \frac{5}{12}[/tex]
Therefore the value of the tanP is 5/12.

i tried working this out but it doesnt make sense, at least the table doesnt... did you make this question up or get it off of a school assignment??
Answer: Option A; 19
Step-by-step explanation:
The data is:
We have 40 students.
16 play football
9 play basketball
4 play bot sports.
We want to find the number of students that do not play either sport, for this we should add the number of students that play football and the number of students that play basketball, subtracting the number of students that play both sports (because we sill be counting those two times, this is because those 4 students are included in the 16 for football and also in the 9 for basketball.)
N = 16 + 9 - 4 = 12 + 9 = 21
the number of students that do not play basket or football is equal to:
40 - N = 40 - 21 = 19
The correct option is A

An isosceles triangle ABC with the base BC is inscribed into a circle. Find the measure of angles of it, if measure of arc BC=102°.
Answer:
25.5°, 25.5°, 129° and 51°, 64.5°, 64.5°
Step-by-step explanation:
if you read the problem carefully you will notice that there are actually 2 ways of solving this problem. the first is by looking at the arc as if it is across from angle A, while the second is so the arc is across from side BC and bisected by point A (because the triangle is isosceles).
first way:
102/2=51°=m∠A
180-51=129°=m∠B+m∠C
129/2=m∠B=m∠C=64.5°
answers: 64.5°, 64.5°, 51°
second way:
102/2=51
51/2=m∠B=m∠C=25.5°
180-51=129°=m∠A
answers: 25.5°, 25.5°, 129°

The central angle BOC is twice the measure of arc BC, so it is 204°. Since the circle is 360°, the sum of the other two angles is 156°. Being an isosceles triangle, angles ABC and ACB are equal, thus each is 78°.
Explanation:To find the measure of the angles of an isosceles triangle ABC inscribed in a circle, with the measure of arc BC being 102°, we utilize the properties of a circle and the fact that an isosceles triangle has two equal angles. In a circle, the angle subtended by an arc at the center is twice the angle subtended on the circumference. Thus, if the measure of arc BC is 102°, the central angle BOC would be 204° (since it's twice the angle at the circumference).
This central angle separates the circle into two segments, one of which is the base of the isosceles triangle. The other two angles of the triangle, angles A and ABC or ACB (since it's an isosceles triangle, these angles are equal), will each occupy the remaining portion of the circle that amounts to 360° - 204° = 156°. Since the angles at B and C are equal in an isosceles triangle, we divide the remaining 156° by 2 to find each angle. Therefore, angle A = 204°, and each of the other two angles is 78°.

Angles C and D are supplementary, meaning they add up to 180 degrees. So, if we add 8u-48 to 5u+46, we get 13u-2. We set that equal to 180, so 13u-2=180. Add the two, so 13u=182. Divide the 13, so u=14. To double check, plug in 14 to both expressions. 8(14)-48 and 5(14)+46. 8(14)-48 is 64. 5(14)+46 is 116. If you add 64+116, you get 180, which proves your answer right! So u= 14

I need help on how to solve this question. I’ve researched how to do inequality’s and still Stuck.
Answer:
J
Step-by-step explanation:
The amount he is spending PER DAY is always a variable multiplied by its rate. That will be 8d.
Then you have a MAXIMUM amount of 3,000. That means the amount has to be less than or even equal to 3,000 but no more.
So 8d ≤ 3000 would be the answer
I believe the answer would be J. whenever the open part of the sign is towards a number or value, that means it is greater than the other number on the other side. For example 5 is less than 6 so 5 < 6. whenever the sign in between and has a line underneath it, it means it can also be equal to the number. therefore d is the amount per day and you pay that much for 8 days, so you get 8d. Now we know you can spend $3000, but no more. so you would use this sign < with a line drawn underneath it. now you would have 8d <(with a line underneath) 3000. this means that I'd must be equal to $3000 or less than $3000.

Answer:
Step-by-step explanation:
when the two angles are added they are equal to 180 degree. (corresponding angles property)
x+8+3X+2=180
4X+10=180
4X=170
X=44.25 DEGREES
Question 1:
For this case we have that by definition, if a and b are two parallel lines, then the corresponding angles are congruent, that is, we can write 3x + 2 and x + 8 as supplementary angles:
[tex](3x + 2) + (x + 8) = 180\\3x + 2 + x + 8 = 180\\4x + 10 = 180\\4x = 180-10\\4x = 170\\x = \frac {170} {4}\\x = 42.5[/tex]
We look for the value of the angles:
[tex]3 (42.5) + 2 = 129.5\ degrees\\42.5 + 8 = 50.5 \ degrees[/tex]
ANswer:
[tex]x = 42.5\\3 (42.5) + 2 = 129.5\ degrees\\42.5 + 8 = 50.5 \ degrees[/tex]
Question 2:
For this case we have that by definition, the equation of a line of the slope-intersection form is given by:
[tex]y = mx + b[/tex]
Where:
m: It's the slope
b: It is the cutoff point with the y axis
Now, in the equation [tex]y = 2x + 3[/tex]
[tex]m = 2\\b = 3[/tex]
By definition, if two lines are parallel, their slopes are equal. Also, if two lines are perpendicular, then the product of their slopes is -1.
So:
The slope of a line parallel to the given line is:
[tex]m = 3[/tex]
The slope of a line perpendicular to the given line is:

Since we want to solve for x, we take the log_3 of both sides.
So [tex]log_{3}3^x[/tex]=[tex]log_{3}6.87[/tex]
Using the laws of logs, we get
[tex]x*log_{3}3[/tex]=[tex]log_{3}6.87[/tex]
since [tex]log_{3}3[/tex] is 1, we get
X=[tex]log_{3}6.87[/tex]
