what is the equation of the line
Answer:
y=-x+3.
Step-by-step explanation:
The graph goes down one and right one before making another point. This means that the slope is -1/1. Simplify and you get -1. So far we have y=-1x. -1x is the same as -1. Now we have y=-x. The graph intersects the y-axis at the point (0,3). This makes our y-intercept 3. Our final equation is y=-x+3.

OVERDUE PLEASE HELP OR I’LL CRY
Answer:
x = 9
Step-by-step explanation:
combine all the equations and set it equal to 360
10x+ 7 + 88 + 127 + 5x+3 = 360
then combine like terms
15x + 225 = 360
then solve the equation by moving 225 to the right side of the equation
15x = 135
divide both sides by 15
x = 9

The measure of the exterior angle of the triangle is
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that's supplementary to the third interior angle
2x - 2 = 45 + x
2x - x = 45 + 2
x = 47°
Answer:
x = 47
Step-by-step explanation:
Finding the third angle (y) of the triangle:
- Since angles on a straight line add up to 180:
2x -2 + y = 180
y = -2x + 2 + 180
= -2x + 182
Hence, the third angle of the triangle is -2x + 182.
Since all 3 angles of a triangle add up to 180°:
-2x + 182 + x + 45 = 180
-2x + x + 227 = 180
-2x + x = 180 - 227
-x = -47
x = 47
Hence, x = 47

Vanessa wants to determine the perimeter around her garden. She makes an small model of her garden and combines all the sides: 3x + (x + 10) + 5x + (2x + 2). She concludes that the total perimeter of her garden is 56.
Solve the following equation to determine the value of x:
3x + (x + 10) + 5x + (2x + 2) = 56
Answer:
4
Step-by-step explanation:
since it's all addition, we can remove the parentheses
[tex]3x + x + 10 + 5x + 2x + 2 = 56[/tex]
Now we combine like terms
[tex]3x+x+5x+2x+10+2=56[/tex]
[tex]11x+12=56[/tex]
We subtract both sides by 12 to get,
[tex]11x=44[/tex]
now we divide both sides by 11
[tex]x=\frac{44}{11}[/tex]
[tex]x=4[/tex]
Find the coordinates of the x intercept and y intercept
Answer:To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. ...
To find the x-intercept, set y = 0 \displaystyle y=0 y=0.
To find the y-intercept, set x = 0 \displaystyle x=0 x=0.
answer is in there at the bottem
Step-by-step explanation:
Seven less than the sum of p and t is as much as 6.
P + t -7 =6
10+3-7=6
10+3=13
13-7=6
P=10 t=3
The values of the numbers p and t will be 10 and 3 respectively.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The value of the numbers will be calculated as:-
P + t -7 =6
10+3-7=6
10+3=13
13-7=6
P=10 t=3
Therefore, the values of the numbers p and t will be 10 and 3 respectively.

The side length of a square with an area of 49
Answer:
7
Step-by-step explanation:
A square has 4 sides, all of equal length. We can simply find the square root of the area to find the length and width, or length of each side. So to find the length, you find the square root of the area.
[tex] \sqrt{49} = 7[/tex]

Most intruments produce notes across ranges called octaves which are made up of 8 notes how many octaves do 51 notes span?
Answer: 51 notes span 6 octaves.
Step-by-step explanation:
The word "octave" is a Latin word that means "eight".
In an instrument, Each octave is made up of 8 musical notes.
If we have 51 notes , the number of octaves can be made in it = [tex]\dfrac{51}{8}[/tex]
[tex]=6.375\approx6\ \ \ \ \ \text{[Rounded to the nearest whole number]}[/tex]
Hence, 51 notes span 6 octaves.

6 + 4x - 9 what is the awnser
Answer:
y = 5
Step-by-step explanation:
4×(x -3y = -6 ) ➡ 4x - 12y = -24
4x -12y - 4x +9y = 9 - 24 ➡ -3y = -15
y = 5 use this value to find x
x - 3×5 = -6

PLEASE EXTRA POINTS I REALLY NEED HELP!!! 1. A ski lift carries Carol up a slope at a rate of 5 mph.
She skis down the slope, parallel to the lift, at a speed of
20 mph. The round trip takes 45 minutes.
Write and solve a system of equations to determine
how far she skis.
System:
Defined variables:
Solve:
Solution as a sentence:
Hi sorry for the late response, I know the assignment was due at 5pm today but anyway here is the answer.
System:
d= 5(0.75-t)
d= 20t
20t = 3.75 -5t
Define Variables:
d = how far Carol Skied
t = time it took Carol to go up/down
Solve:
20t = 3.75 -5t
20t + 5t = 3.75 -5t + 5t
25t = 3.75
25t/25 = 3.75/25
t = 0.15
Now we plug in the time into the Distances:
20t = 3.75 - 5t
20(0.15) = 3.75 - 5(0.15)
3 = 3.75 - 0.75
3 = 3
