What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is the y-intercept.
The slope of the linear function that is represented by the table,
Slope, m = [(-3/5) - (-13/30)]/[(2/3)-(1/4)]
= [(-18+13)/30] / [(8-3)/12]
= -(12/30)
= -(2/5)
The y-intercept of the linear function that is represented by the table can be found by substituting the coordinate of any one point in the equation of the line.
[tex]y = mx + c\\\\-(\dfrac{2}{15}) = -(\dfrac{2}{5})(-\dfrac12) + C\\\\-\dfrac{2}{15} = \dfrac15 + C\\C = -\dfrac5{15}\\\\C = -\dfrac13[/tex]
Hence, The slope is Negative two-fifths, and the y-intercept is Negative one-third. Hence, the correct option is A.

Check all that apply
O A. x= 3
B. X= -7
O C. x = 21
O D. x= -5
O E. x= 4
Answer:
Step-by-step explanation:
Solving quadratics is easy. With no coefficient to the x^2, we can go right to finding factors. We want two numbers that multiply to -21, and add to 4. Our numbers are 7, and -3. Now, we move the numbers around to be (x-3) and (x+7). We know that these both equal 0, so we can do basic algebra to solve for x. We can subtract 7 to the other side to just get x, and add 3 over because it is subtracted by x. This leaves us with our answers:
x = -7, x = 3

If two sides of a triangle are 6 and 16, what is the range of the possible lengths of the third side?
Answer:
10 < x <22
Step-by-step explanation:
The smallest side must be larger than the difference of the two sides
16-6 = 10
x>10
The largest side must be smaller then the sum of the two sides
6+16 =22
x< 22
Put this together
10 < x <22
Answer:
10 < c < 22
Step-by-step explanation:
Remember the Triangle Inequality Theorem.
For a triangle with sides a, b, and c:
- a + b > c
- a + c > b
- b + c > a
Let's arbitrarily say a = 6 and b = 16. Then:
a + b > c
6 + 16 > c
c < 22
a + c > b
6 + c > 16
c > 10
b + c > a
16 + c > 6
c > -10
Thus, the range of possible lengths of the third side, c, is 10 < c < 22.

Answer: The first one is 144 . The second one is C.
Step-by-step explanation:
Answer:
1) Full surface area = 156unit^2 this is correct.
lateral surface area = 144unit^2, this wasn't asked.
2) C = 528unit^2 is correct.
Lateral = 480unit^2 this wasnt asked.
Step-by-step explanation:
yes the next one is C 528
The formula for finding the surface area is the same for all right prisms and is: Surface area = 2B + hP. In this formula, B is the area of one of the bases, while h is the prism's height, and P is the perimeter of the base.
In effect;
step 1 = parallel sides indicate the bases of all triangular prism
step 2 = perimeter = 3+4+5 = 12
step 3 = LA = P x H = P x Length which is lateral height
LA = 12 x 12 = 144
step 4 = SA = 1/2 b x h (height of triangle) +LA
SA = 1/2 4 x 3 + LA
SA = 2 x 3 = 6 = 1 base + LA (+base)
SA = 6+6 = 12 + 144 = 156 = 2b+LA
IF you remember LA is perimeter x length of prism but label L as H then use little h for triangle h. You can remember.

For what values of k the relation R:{(k2 , 5), (3k, 6)} is not a function?
Explanation:
If you have repeated x values, then you wont have a function. For example, the points (1,5) and (1,6) mean we don't have a function since the input x = 1 leads to multiple outputs y = 5 and y = 6 simultaneously. For a function to be possible, we must have any input lead to exactly one output only.
What we do is set the x coordinates (k^2 and 3k) equal to each other and solve for k
k^2 = 3k
k^2-3k = 0
k(k-3) = 0 .... factoring
k = 0 or k-3 = 0 .... zero product property
k = 0 or k = 3
If k = 0, then (k^2,5) becomes (0,5). Also, (3k,6) becomes (0,6). The two points (0,5) and (0,6) mean the graph fails the vertical line test.
Similarly, if k = 3, then (k^2,5) becomes (9,5) and (3k,6) = (9,6). Another vertical line test failure happens here to show we don't have a function.

Find the total volume of the figure.
Answer:
The Volume is 2,200
Step-by-step explanation:
10+8.8= 18.8
13.7+25= 38.7
18.8+38.7= 57.5
This is the incorrect way
__________________________________________________
Correct way:
Volume= L×H×W
25 × 8.8 × 10 = 2,200
The total volume of the figure is 693 m³.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
Given a composite figure consisting of a triangular pyramid and a triangular prism.
Total volume of the figure = Volume of pyramid + volume of prism
Volume of the pyramid = 1/3 × base area × height
Base area = 1/2 × √(13.7² - 8.8²) × 8.8
= 1/2 × 10.5 × 8.8
= 46.2 m²
Volume of the pyramid = 1/3 × 46.2 × (25 - 10)
= 231 m³
Volume of the prism = base area × height
= 46.2 × 10
= 462 m³
Total volume = 231 m³ + 462 m³ = 693 m³
Hence the total volume is 693 m³.
