Write an equation of the line containing the given point and parallel to the given line.
(6,-2); 4x - 3y = 8
Answer:
y = (4/3)x − 10
Step-by-step explanation:
Rewrite in slope-intercept form.
The slope-intercept form is y = mx + b, where m is the slope and b is they-intercept.
y = mx + b
Subtract 4x from both sides of the equation.
−3y = 8 − 4x
Divide each term by −3 and simplify.
Divide each term in −3y = 8 − 4x by −3.
(−3y/−3)= (8/−3) + (−4x/−3)
Cancel the common factor of −3.
y= (8/−3) + (−4x/−3)
Simplify (8/−3) + (−4x/−3)
y= (4x/3 - 8/3)
Reorder terms.
y= 4x/3 - 8/3
Using the slope-intercept form, the slope is 4/3
m = 4/3
To find an equation that is parallel, the slopes must be equal. Find the parallel line using the point-slope formula.
Use the slope 4/3 and a given point (6, −2) to substitute for [tex]x_{1}[/tex]and [tex]y_{1}[/tex]in the point-slope form. [tex]y[/tex] − [tex]y_{1}[/tex] = [tex]m[/tex] ([tex]x[/tex] − [tex]x_{1}[/tex]) which is derived from the slope equation[tex]m=[/tex] ([tex]y_{2}[/tex]− [tex]y_{1}[/tex])/([tex]x_{2}[/tex] - [tex]x_{1}[/tex])
y − (−2) = (4/3) ⋅ (x − (6))
Simplify the equation and keep it in point-slope form.
y − (−2) = (4/3) ⋅ (x − (6))
solve for y
y = (4/3)x − 10
whats 3(x + 2) = 21?
show work please !!
Answer:
x=5
Step-by-step explanation:
[tex]3(x+2)=21[/tex]
[tex]3x+6=21[/tex]
[tex]3x+6-6=21-6\\\\3x=15\\\\\frac{3x}{3} = \frac{15}{3} \\\\x=5[/tex]
Answer:
x = 5
Step-by-step explanation:
You first have to multiply 3 by x and 2, and you would get 3x and 6. 3(x + 2)=3x +6
Then you have to move the 6 to the other side and it will become negative. 3x= -6 +21
Then you subtract 21-6 to get 15. 3x = 15
Then you are left with 3x = 15.
Divide 3 from both sides and you get x =5.

In the figure below, determine the perimeter of triangle EFG
Answer:
82 units
Step-by-step explanation:
From the image, we can see that the 2 triangles are similar triangles.
Thus:
BC = EF
BD = EG
CD = FG
Now, BD = 4x - 9 and EG = 2x + 15
Thus;
4x - 9 = 2x + 15
4x - 2x = 15 + 9
2x = 24
x = 24/2
x = 12
Thus, in triangle EFG where EG = 2x + 15, then EG = 2(12) + 15 = 39
Also, EF = BC = 17
FG = 26
Thus, perimeter of triangle EFG is;
P = 26 + 17 + 39
P = 82 units
What is the y-intercept of the equation of the line that is perpendicular to the line v= x -x+ 10 and passes through the
point (15,-5)?
O y=xx-20
O y=-3x+20
Ov=3x-2
Ov=-3x+20
Answer:
[tex]y=-\frac{5}{3}x+20[/tex]
Here, m=-5/3, and b=y-intercept=20
Here, the y-intercept is: 20
Thus, option (d) is true.
Step-by-step explanation:
Given the equation
[tex]y=\frac{3}{5}x+10[/tex]
comparing the equation with the slope-intercept form
[tex]y=mx+b[/tex]
Here,
m is the slope y is the interceptso the slope of the line is 3/5.
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
The slope of the perpendicular line will be: -5/3
Therefore, the point-slope form of the equation of the perpendicular line that goes through (15,-5) is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-5\right)=\frac{-5}{3}\left(x-15\right)[/tex]
[tex]y+5=\frac{-5}{3}\left(x-15\right)[/tex]
simplifying the equation to convert it into the slope-intercept form
We know that the slope-intercept form of the line equatio is
[tex]y=mx+b[/tex]
here 'm' is the slope and 'b' is the y-intercept
[tex]y+5=\frac{-5}{3}\left(x-15\right)[/tex]
subtract 5 from both sides
[tex]y+5-5=\frac{-5}{3}\left(x-15\right)-5[/tex]
[tex]y=-\frac{5}{3}x+20[/tex]
Here, m=-5/3, and b=y-intercept=20
Here, the y-intercept is: 20
Thus, option (d) is true.

Judy is baking 5 cheesecakes. A recipe for one of the cheesecakes requires 1 1 2teaspoons of vanilla. Judy's bottle of vanilla contains 12 teaspoons of vanilla. After Judy bakes the 5 cheesecakes, how many teaspoons of vanilla will be left in the bottle?
Answer:4 1/2 Teaspoons of vanilla will be left in the bottle
Step-by-step explanation:
Step 1
Recipe for 1 cheesecake = 1 1/2 teaspoons of vanilla
Since she s making 5 cheesecakes, she will requite = 5 x 1 1/2 teaspoons
= 5 x 3/2= 15/2 = 7 1/2 teaspoons of vanilla.
Step 2
If a bottle of vanilla contains = 12 teaspoons of vanilla
After baking 5 cheesecakes which consumed = 7 1/2 teaspoons of vanilla
Teaspoons left of vanilla = Total teaspoons of vanilla-teaspoons of vanilla used for 5 cheesecakes= 12 - 7 1/2 =4 1/2
Therefore 4 1/2 Teaspoons of vanilla will be left in the bottle

HELP ASAP PLZ What value of d makes the equation (3d – 2) = }(d + 5) true?
1 Remove parentheses.
3d-2=d+5
2 Add 22 to both sides.
3d=d+5+2
3 Simplify d+5+2 to d+7.
3d=d+7
4 Subtract d from both sides.
3d-d=7
5 Simplify 3d-d to 2d.
2d=7
6 Divide both sides by 2.
7/2=d
7 Flip sides.
d=7/2
(Optional decimal form)
d=3.5
So 7/2 or 3.5

A small business has 15 full-time employees. How many people does the small business employ if the full-time workers make up 30% of the employees the company has?
Answer:
50 employees
Step-by-step explanation:
The total number of employees the business has will have to be made up the full-time employees and part-time employees.
The number of full-time employees = 15
Let the total number of employees = x
[tex]15 = 30 percent of x[/tex]
[tex]15 = 30/100 \times x\\x=1500/30 = 50[/tex]
The company has a total of 50 employees

The earth spins 360 degrees about its axis in 24h. How many degrees does it spin in 10h?
if I get another unreasonable answer OHFUSHASHDF
Answer:
150
Step-by-step explanation:
To find out how much it spins in one hour do 360 divided by 24= 15, and you need to find how much it spins in 10 hours so do 15 x 10=150
Answer:
150 degrees.
Step-by-step explanation: Just divide 360 by 24 then times by 10.
Ella swims four times a week at her club's pool. She swims the same number of laps on Monday, Wednesday, and Friday, and 15 laps on Saturday. She swims a total of 51 laps each week. Write an equation for the problem.
Answer:
Equation for the problem
3x + 15 = 51 laps
Hence
She swims on
Monday: 12 laps
Wednesday : 12 laps
Friday = 12 laps
Step-by-step explanation:
Ella swims four times a week at her club's pool.
We are told that:
She swims the same number of laps on Monday, Wednesday, and Friday.
Hence, the number rod times that she swims on Monday, Wednesday and Friday is represented by x
Also, she swims 15 laps on Saturday. She swims a total of 51 laps each week. Equation for the problem
= x + x + x + 15 = 51 laps
3x + 15 = 51 laps
Hence
3x = 51 - 15
3x = 36
x = 36/3
x = 12 laps
Therefore, She swims on:
Monday: 12 laps
Wednesday : 12 laps
Friday = 12 laps
