Answer:
y= -2x +2
Step-by-step explanation:
The equation of a line can be written in the form of y= mx +c, where m is the gradient and c is the y-intercept. This form is known as the slope-intercept form.
To find the value of m, use the gradient formula below:
[tex]\boxed{gradient = \frac{y1 - y2}{x1 - x2} }[/tex]
[tex]m = \frac{6 - ( - 4)}{ - 2 - 3}[/tex]
[tex]m = \frac{6 + 4}{ - 5} [/tex]
[tex]m = \frac{10}{ - 5} [/tex]
m= -2
Substitute m= -2 into the equation:
y= -2x +c
To find the value of c, substitute any pair of coordinates that the line passes through into the equation. Here, I am going to substitute the coordinates (3, -4).
y= -2x +c
When x= 3, y= -4,
-4= -2(3) +c
-4= -6 +c
c= -4 +6
c= 2
Thus, the equation of the line is y= -2x +2.

Use the distance formula to calculate the distance between the following two points:
(-1,1) and (4, 11)
The distance between the two points is approximately
units.
Answer:
d = 11 units if rounded to nearest whole number
Step-by-step explanation:
Distance formula:
d=√((x_2-x_1)²+(y_2-y_1)²)
Your ordered pairs (-1, 1) and (4, 11)
d=√((4-(-1))²+(11-1)²)
d=√((4+1))²+(10))²)
d=√((5)²+ 100)
d = √125
d = 11.18
d = 11 units if rounded to nearest whole number

Step-by-step explanation:
Cone:
r = 8/2 = 4 ft
h = 16 - 12 = 4 ft
Volume = [tex]\frac{1}{3}\pi r^{2}h\\[/tex]
[tex]= \frac{1}{3}*3.14*4*4*4\\\\=\frac{200.96}{3}\\\\= 66.98\\\\= 67 cubic feet\\[/tex]
Cylinder:
r = 4 ft
h= 12 ft
Volume = πr²h
= 3.14*4*4*12
= 602.88
= 603 cubic feet
Step-by-step explanation:
the formular for finding the volume( how much it can contain in this instance) of the cone(spout) is
[tex] \frac{1}{3} \times \pi \times {r}^{2} \times l[/tex]
r is the radius of the cone l is the height of the cone π = 22/7
1/3 × 22/7 × 4 × 4 × 4
diameter divide by 2 gives the radius 8/2 = 4
the height of the whole shape - the height of the upper part(cylinder) gives the height of the cone
16 - 12 = 4
volume of spout(cone)=22/21 × 64 =67 cubic feet(f^3)

Answer:
L= 90, M=53, K=37
Step-by-step explanation:
Tilt your phone/computer to the right, and you'll see the 90° angle for L. Now you're left with two more, and just compare which angle is bigger, K or M. M is bigger, so you apply the bigger number out of the you got which is 53. Now no doubts, K is 37.
What is the slope of the line?
Answer:
1
Step-by-step explanation:
Two ordered pairs that can be seen are (0,1) and (1,2)
Using delta y/ delta x,
(2-1)/(1-0) = slope
slope = 1/1
slope = 1
Answer:
slope = 1
Step-by-step explanation:
To find the slope of the line, use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], in which [tex]m[/tex] represents the slope. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, while the [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point.
Thus, locate two points on the line. We can see that the line intersects (-1,0) and (0,1), thus we can use them for the formula. (Any other two points that are also on the line will also work.) Substitute their x and y values into the appropriate places in the formula and solve:
[tex]m = \frac{(1)-(0)}{(0)-(-1)}\\m = \frac{1-0}{0+1} \\m = \frac{1}{1} \\m = 1[/tex]
Thus, the slope is 1.

Answer:
1. Complementary Angles.
2. x=60°
Step-by-step explanation:
Part 1:
*Note: A complementary angle is when the sum of two angles equal 90 degrees. A Supplementary angle is when the sum of 2 angles equals 180 degrees.
In this instance, the 2 angles equal 90 degrees, as indicarted by the box on the angle. Therefore, the the angles are complentary.
Part 2:
1. Since we know that the sum of the two angles (x-30 and x) is 90 degrees, we can write an equation which says: (x-30) + x=90.
2. Then we'd simplify the equation by adding the like variables, and adding 30 to both sides:
2x=120
3. Now we will divide both sides by 2
[tex]\frac{2}{2} x=\frac{120}{2} \\x=60[/tex]
4. As a result, we get x=60, now label your answer with the degree sign, and enjoy your answer.

Answer:
x = 63
Step-by-step explanation:
a triangle is always 180 degrees, so you equation would be:
180 - 42 - 43 - 32 = x
180 - 42 - 43 - 32 = 63
so x = 63
Answer:
Step-by-step explanation:
a straight line = 180 degrees
on the right side, where the angle is 32 it is vertically opposite to the right angle of the triangle then

Answer:
f(x) = 2ˣ + 1
Step-by-step explanation:
Based on the exponential increase, you know that it will be an exponential equation, meaning that you can cancel out the first two options.
The easiest way to do pick the between the two remaining equations is by plugging in an x-value and seeing if the y-value for that equation matches the y-value from the equation.
For (3, 9):
f(x) = 3ˣ = 3³ = 27
f(x) = 2ˣ + 1 = 2³ + 1 = 8 + 1 = 9
The last equation is the equation that is represented by the table.
