D. 1/8Step-by-step explanation:
Use the slope formula:
[tex]m=(y_2-y_1)/(x_2-x_1)[/tex][tex]m=(-4-(-5))/(0-(-8))=1/8[/tex]Calculate the slope of the line, given the points (-3, -4) and (-2, 1)
Answer:
The slope of the line is m=5
Step-by-step explanation:
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
Challenge A gold mine has two elevators, one for equipment and another for the miners. The
equipment elevator descends 6 feet per second. The elevator for the miners descends 15 feet per
second. One day, the equipment elevator begins to descend. After 21 seconds, the elevator for the
miners begins to descend. What is the position of each elevator relative to the surface after
another 17 seconds? At that time, which elevator is deeper?
The position of the equipment elevator relative to the surface is feet.
Step-by-step explanation:
The equipment elevator is at a depth of 176 feet (-176 feet), while the miners elevator is at a depth of 210 feet (-210 feet) below the surface
ii. The miners elevator is deeper than that of the equipment.
The speed of an object is the rate at which the object moves.
i.e speed = \frac{distance}{time}
time
distance
Thus,
Speed of the equipment elevator = 4 feet per second
Speed of the miners elevator = 15 feet per second.
Time of descent of the equipment elevator = 30 + 14
= 44 seconds
So that, the distance of the elevator at this time is;
speed = \frac{distance}{time}
time
distance
⇒ distance = speed x time
= 4 x 44
= 176
distance = - 176 feet
The distance of the miners elevator after 14 seconds is:
speed = \frac{distance}{time}
time
distance
⇒ distance = speed x time
= 15 x 14
= 210
distance = - 210 feet
Thus after another 14 seconds, the equipment elevator is at a depth of 176 feet (-176 feet), while the miners elevator is at a depth of 210 feet (-210 feet) below the surface.
Therefore, the miners elevator is deeper than that of the equipment.
Calculate the slope between the points: (4,-9) and (5,1)
Answer:
10
Step-by-step explanation:
1. The formula to find the slope of a line given two points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. All we have to do is plug in the values and simplify.
2. (Solving)
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex] [tex]\frac{1-(-9)}{5-4}[/tex] [tex]\frac{1+9}{1}[/tex] [tex]\frac{10}{1}[/tex] [tex]10[/tex]Therefore, the slope is 10.

Is the relationship shown by the data linear? If so, model the data with an equation.
A. The relationship is linear; y + 7= 1/2(x - 5).
B. The relationship is linear; y - 5= -1/2(x + 7).
C. The relationship is not linear.
D. The relationship is linear; y – 5 = 2(x + 7).
Answer:
D. The relationship is linear; y – 5 = 2(x + 7).
Step-by-step explanation:
The correct answer is:
The relationship is linear, and the equation is
y-5 = 2(x+7).
Explanation:
To determine if the relationship is linear, we find the slope between each pair of points. Slope is given by the formula:
The slope between the first two points is given by:
The slope between the second pair of points is given by:
The slope between the third pair of points is given by:
Since the slope is the same throughout the data, the relationship is linear and the slope is 2.
To write the equation, we use point-slope form, which is:
y-y₁ = m(x-x₁)
Using the first point, we have:
y-5 = 2(x--7)
y-5 = 2(x+7)
The answer is The relationship is linear; y - 5 = 2(x + 7).

- 4x + 11y = 15
X = 2y
Y =
X =
Answer:
x = - (15 - 11y)/4
y = x/2
Step by step explanation:Let's first solve for x
=>- 4x + 11y = 15
=>- 4x + 11y - 11y = 15 - 11y
=>- 4x = 15 - 11y
=>(- 4x)/- 4 = 15/- 4 - (11y)/- 4
x = - (15 - 11y)/4
let's solve for y
=>x = 2y
=>2y = x
=>(2y)/2 = x/2
y = x/2
Answer:
x = 10y = 5Step-by-step explanation:
Given system:
- 4x + 11y = 15 x = 2ySolve by substitution:
- 4(2y) + 11y = 15- 8y + 11y = 153y = 15y = 5Find x:

write each equation explicitly in terms of x: (with steps)
1) y^2 -x^2 + 1 = 50
2) y^2 +6y +9 = x + 8
Step-by-step explanation:
y2−x2+1=50
Step 1: Add -y^2 to both sides.
−x2+y2+1+−y2=50+−y2
−x2+1=−y2+50
Step 2: Add -1 to both sides.
−x2+1+−1=−y2+50+−1
−x2=−y2+49
Step 3: Divide both sides by -1.
−x2
−1
=
−y2+49
−1
x2=y2−49
Step 4: Take square root.
x=√y2−49 or x=−√y2−49
Answer:
x=√y2−49 or x=−√y2−49
y2+6y+9=x+8
Step 1: Flip the equation.
x+8=y2+6y+9
Step 2: Add -8 to both sides.
x+8+−8=y2+6y+9+−8
x=y2+6y+1
Answer:
x=y2+6y+1
What is the domain and range of the following function
Answer:
domain: (–∞,∞) or all real numbers
range: (–∞,∞) or all real numbers
Step-by-step explanation:
domain is left to right (x-axis). looking at the graph, as you go from left to right, the x-values are infinitely getting more negative and positive.
range is bottom to top (y-axis). as you go from bottom to top, the y-values are infinitely getting more negative and positive.

0.34156020 as a scientific notation
Answer:
3.4156020*10^-1 for scientific notation if you want to keep that ending zero (I'd normally write it 3.415602*10^-1)
Step-by-step explanation:
So the idea of scientific notation (or engineering notation) is to make things smaller and more manageable. The idea is to move the variables so that one is in front of the point.
So if you had something like this:
12342300000000000000
It'd be equal to 1.23423*10^19
Or something like this
0.0000095675
Would be 9.5675*10^-6

Answer:
The remainder is 40.
Step-by-step explanation:
We're applying synthetic division here.
The coefficients of this function are {1, 6, -3, 0}. The divisor (x + 5) is represented by the monomial divisor -5.
Setting up synthetic division, we get:
-5 1 6 -3 0
-5 -5 40
---------------------
1 1 -8 40
The remainder is 40.

5. m∠8 is 114°
6. m∠6 is 124°
7. m∠7 is 66°
8. m∠2 is 66°
What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
1. If two parallel lines are cut by a transversal then the pair of consecutive interior angles are supplementary.
2. If two parallel lines are cut by a transversal then pair of alternate interior angles are equal.
3. m∠2 is 74° then m∠1 is (180 - 74)° = 106°. (linear pair of angles)
4. m∠2 is 74° then m∠3 is 74°. (vertically opposite angles)
5. m∠1 is 114° then m∠8 is 114° (alternate angles)
6. m∠4 is 56° then m∠6 is (180 - 56)° = 124° (180° - m∠5)
7. m∠1 is 84° then m∠7 is (180° - m∠8) = 180° - 114° = 66°.
8. m∠8 is 114° then m∠2 is m∠7 = 66°

The degrees on a triangle add up to 180.
(x) + (x-7) + (3x+12) = 180 ; Just shwoing what i'm doing.
x + x-7 + 3x + 12 = 180
5x + 5 = 180 ; x + x + 3x = 5x , 12 - 7 = 5
5x = 175 ; Subtract 5 from 180
x = 35 ; 175/5 = 35
x=35
P: x - 7 = 35 - 7 = 28
Q: 3 (x) + 12 = 3 (35) + 12 = 105 + 12 = 117
R: x = 35
P= 28 degrees, Q= 117 degrees, R= 35 degrees.

Hey there!
2(p + 1) + 8(p - 1) = 5p
2(p) + 2(1) + 8(p) + 8(-1) = 5p
2p + 2 + 8p - 8 = 5p
10p - 6 = 5p
SUBTRACT 5p to BOTH SIDES
10p - 6 - 5p = 5p - 5p
SIMPLIFY IT!
5p - 6 = 0
ADD 6 to BOTH SIDES
5p - 6 + 6 = 0 + 6
CANCEL out: -6 + 6 because it gives you 0
KEEP: 0 + 6 because it helps solve for the p-value
5p = 0 + 6
5p = 6
DIVIDE 5 to BOTH SIDES
5p/5 = 6/5
CANCEL out: 5/5 because it gives you 1
