Complete the steps to find the value of x.
Answer:
72+(7x+24)=180
7x+96=180
7x=84
x=12
Step-by-step explanation:
Answer: x = 12.
Step-by-step explanation:
72 + (7x + 24) = 180 Now we add like terms
96 + 7x = 180 Take away 96 from both sides
7x = 84 Divide both sides by 7
x = 12 X equals 12.
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
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).

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
---------------------

Find the measure of Z8 given angle 2 is 70 degrees.
Angle 8 and Angle 2 are supplementary. So Angle 8 + 70 would equal to 180.
180-70 is 110 hence angle is 110 degrees.
For the figure shown on the right, find the value of the variable and the measures of the angles.
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.
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.
Find the area of the triangle below.
Be sure to include the correct unit in your answer.
14 yd
15 yd
17 yd
Answer:
A = 42.5 yd²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 17 and h = 5 , then
A = [tex]\frac{1}{2}[/tex] × 17 × 5 = [tex]\frac{1}{2}[/tex] × 85 = 42.5 yd²
- 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:
x = 2*5 = 10Three less than the product of a number and four

Step-by-step explanation:
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.
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.

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∠1 is 106°.
4. m∠3 is 74°
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°

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

Given the arithmetic sequence {-12, -7, -2, 3, ...} what is the 15th term of the sequence?
Group of answer choices
58
33
43
48
63
Answer:
58
Step-by-step explanation:
We are given the arithmetic sequence:-
-12,-7,-2,3,...
First, find the common difference which we can obtain by:-
[tex] \displaystyle \large{d = a_{n + 1} - a_n}[/tex]
Check:-
-7-(-12) = -7+12 = 5
-2+7 = 5
3+2 = 5
Therefore, our common difference is 5.
General Arithmetic Term
[tex] \displaystyle \large{a_n = a_1 + (n - 1)d}[/tex]
Since we want to find the 15th term, substitute a1 = -12, n = 15 and d = 5.
[tex] \displaystyle \large{a_{15}= - 12 + (15 - 1)5} \\ \displaystyle \large{a_{15}= - 12 + (14)5} \\ \displaystyle \large{a_{15}= - 12 + 70} \\ \displaystyle \large{a_{15}= 58} \\ [/tex]
