Answer:
y = - x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 1) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line
m = [tex]\frac{-1-1}{0+2}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1
The line crosses the y- axis at (0, - 1 ) ⇒ b = - 1
y = - x - 1 ← equation of line
Answer:
y= - x -1
Step-by-step explanation:
ran it through Desmos
I can't find a way to expllain
it if i would put y= - 1 (becaues remember -1 is where the lines intersected with the y axis)
all there would be was a straight
line across -1 but since its goin down 1
you need the - x to give it a negative tilt

Answers
Answers:
x = 6 and P = 128
=================================================================
Explanation:
The tangents CT and CU are equal to each other. The rule is that tangent segments that meet at a common point are the same length.
Let's solve for x
CT = CU
3x = 18
x = 18/3
x = 6
Because CT = 18, this makes BC = BT+TC = 12+18 = 30
---------------------------
For similar reasoning as mentioned earlier, we can say tangents BT and BV are the same length. This means BV = 12.
Segment CD = 52 and CU = 18, which makes UD = CD-CU = 52-18 = 34
From there, we can say segment DV = 34 also. This leads to BD = BV+VD = 12+34 = 46
Triangle BCD has the three sides
BC = 30CD = 52BD = 46The perimeter is
P = sum of the three sides
P = (side1)+(side2)+(side3)
P = BC + CD + BD
P = 30+52+46
P = 82+46
P = 128

A dolphin jumps out of the water with an initial velocity of 20 feet per
second (assume its starting height is O feet). Use the vertical motion
model, h = - 16t2 + vt +8, where v is the initial velocity in feet per
second and s is the height in feet, to calculate the amount of time the
dolphin is in the air before it hits the water again. Round your answer
to the nearest tenth if necessary.
Time in air: seconds
Answers
Answer:
1.6 Seconds
Step-by-step explanation:
The equation would be h(t)=-16t^2+20t+8 since 20 is the velocity, and once you input that onto a graph the answer of when it hits the ground is 1.569 seconds, so rounded is 1.6 seconds.

Find the value of r so the line that passes through each pair of points has the given slope.
(1, r), (7, 5), m = 2/3
Answers
Answer:
r = 1
Step-by-step explanation:
slope = change in y / change in x, so:
change in y / change in x = 2/3
5 - r / 7 - 1 = 2/3
5 - r / 6 = 2/3
[tex]\frac{5-r}{6}=\frac{2}{3}[/tex]
now solve this equation.
first, multiply both sides by 6 to get rid of the fraction:
[tex]5 - r = 4[/tex]
subtract 5 from both sides
[tex]-r=-1[/tex]
multiply both sides by -1
[tex]r=1[/tex]
Write down the solution to these simultaneous equations. y=2x + 1 and y= 0.5x - 2
Answers
Answer:
(-2, -3)
Step-by-step explanation:
y=2x + 1
y= 0.5x - 2
2x+1= 0.5x -2
1.5x= -3
x= -2
y= 2x+ 1
y= 2(-2)+1
y= -3
The solution is (-2,-3)
The solution to the set of simultaneous equations is; (-2, -3)
We are given the equations;
y = 2x + 1 ---(eq 1)
y = 0.5x - 2 ---(eq 2)
subtract eq 2 from eq 1 to get;
0 = 2x - 0.5x + 1 - (-2)
0 = 1.5x + 3
x = -3/1.5
x = -2
Thus;
y = 2(-2) + 1
y = -4 + 1
y = -3

My steps:
First thing we do is: Rearrange terms

−4x+15=2(3+1)−4x+15=6x+2Third thing we do is : Subtract 15 from both sides of the equation
−4x+15=6x+2−4x+15−15=6x+2−15Then you carry on and find solution:

1 and 2 I need this before 10 pm please ASAP I need it quick or I get a bad grade
Answers
Answer:
A. 6 feet
B. 38 feet of fencing total
Step-by-step explanation:
a. We are given 78 square feet as the total area that the fence encloses. Given this, we can use the A=l*w to solve for the side lengths.
A=l*w
Plug in known variables and simplify...
Step 1: Subtract 78 from both sides.
x^2+7x−78=78−78
x^2+7x−78=0
Step 2: Factor left side of equation.
(x−6)(x+13)=0
Step 3: Set factors equal to 0.
x−6=0 or x+13=0
x=6 or x=−13
For this case we will need to use the positive value.
so to check the answer, we can plug in 6 for x and check if it will equal 78.
(6+7)(6)
13*6
78
b. now given the value of x, we need to solve for the total amount of fencing by finding the perimeter.
We already know that one side is 6+7 or 13, and the other side is 6, so to find perimeter we use the formula 2l+2w
and solve...
2*13+2*6
26+12
38
