PLZ HELP!!!! Explain 72. Determine the value of r so that a line through the points with the coordinates (r, 4) and (-2,3) has
slope 1/4
a. 4.5
b. 6
c. -2
d. 2
9514 1404 393
Answer:
d. 2
Step-by-step explanation:
The point-slope form of the equation for the line can make use of the given slope and point:
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y -3 = 1/4(x +2) . . . . line with slope 1/4 through point (-2, 3)
Filling in the unknown point values, we have ...
4 -3 = 1/4(r +2)
4 = r + 2
2 = r
_____
Alternate solution
The way the question is worded, you seem to be expected to use the slope formula.
m = (y2 -y1)/(x2 -x1)
For the given points and slope, you have ...
1/4 = (3 -4)/(-2 -r)
-2 -r = 4(-1) . . . cross multiply
2 = r . . . . . . . . add r+4 to both sides
44. Time to Complete a Task Two machines can complete a task in t hours, where t must satisfy the
equation t/8+t/12 = 1. How long will it take for the two machines to complete the task?
Answer:5 h 48 min
Step-by-step explanation:
t/8+t/12=1
=> 3t+2t =24
5t=24
t=24/5
t=5 and 4/5 h
That equal to 5 h and 8/10 h or 5h and 8*6 min
So the answer is 5 h 48 min

The above quadrilateral is a square because of the marking shown for the equilaterality of sides.
We have,
Side of the square = 13We need to find:
Variable x and y?Solution:
x is the side of the square and y is the diagonal. Hence,
[tex] \large{ \boxed{ \sf{x = 13}}}[/tex]
And for finding the diagonal which can use the Pythagoras theoram where the leg sides (p and b) are the sides of the triangle. Hence,
➝ y = √13² + 13²
➝ y = √338.
[tex] \large{ \boxed{ \sf{y = 13 \sqrt{2} }}}[/tex]
The correct option is Option (D)

Gabriela is weighing quarters on a scale. She weighs various numbers of quarters, n, and
records their total weight, w, in grams. Find the ratio of the weight of the quarters to the
number of quarters for all three columns of the table. Express your answer using decimals.
Number of quarters, n 4,10,24
Tirol weight, w 22,55,132
The ratio of the weight of the quarters to the number of quarters will be 11: 2
What is the ratio of two quantities?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b Remember that the ratio should always be taken of quantities with the same unit of measurement. Also, the ratio is a unitless(no units) quantity.
We have been given that Gabriela is weighing quarters on a scale. They weigh various numbers of quarters, n, and record their total weight, w, in grams.
Number of quarters, n; 4,10,24
Tirol weight, w; 22,55,132
The ratio of the weight of the quarters to the number of quarters will be;
w: n
22 : 4 = 11 : 2
Also, 55: 10
11: 2
Again,
132: 4
11: 2
Hence, The ratio of the weight of the quarters to the number of quarters will be 11: 2

Step-by-step explanation:
Anna is x years old, her sister Jane is y years younger. What will the sum of there ages be in 3 years. SORRY IM DUMB
You are not dumb. No one is dumb. Einstein failed math in high school.
Anna is x years old.
Jane is y years younger.
This means the Jane is x - y years old.
In three years, Anna will be x + 3 years old.
In three years, Jane will be (x - y) + 3 years old.
Let S = the sum of their ages in 3 years.
S = x + 3 + (x - y) + 3
S = 2x + 6 - y

what is 8 divided by 3/5
Answer:
13 1/3. have a great day!! :D
Step-by-step explanation:
To solve the equation, you first need to multiply 8 by 3/5's reciprocal, which is 5/3. Reciprocal basically means to flip the fraction. By multiplying 8 by 5/3 you'll get 40/3, which you can simplify to 13 1/3.

Write an equation of a line that passes through (-3, 5) and (-7, 5).
Answer:
y=5
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( 5-5)/( -7 - -3)
= ( 5-5) / ( -7+3)
= 0/-4
The slope is 0
This means it is a horizontal line
Horizontal lines are in the form
y =
The y coordinate is 5
y=5

4(3x + 2) = 4(2x + 3) + 4x
Answer:
x = -4
Step-by-step explanation:
4(3x + 2) = 4(2x + 3) + 4x (distribute the 4's on both sides)
12x + 8 = 8x + 12 + 4x (collect like terms)
12x + 8 = 13x + 12 (subtract 12x on both sides)
8 = x + 12 (subtract 12 on both sides)
-4 = x

Carly can paint 6/7 of a picture in 3/14 of an hour how many pictures can they paint in a full hour
Answer:
4 paintings in a full hour
Work:
Carly painted 6/7 of a picture in 3/14 hours:
6/7=3/14
Which means Carly painted 2/7 of a picture in 1/14 hours:
2/7=1/14
We need to find how many paintings she can paint in 1 full hour, or 14/14 of an hour, how do you get from 1/14 to 14/14? You do multiplication:
1/14 x 14 = 14/14
but there is a rule that says what you do to one side of the equation, you need to do it to the other side too so:
2/7 x 14=1/14 x 14
28/7=14/14
28/7=4

i can’t put the equal to thing on here but there is supposed to be a line under the greater than symbol
Answer:
[tex]g\geq +/- 3i[/tex]
Step-by-step explanation:
Using clues given in the problem, we can set up a solvable inequality.
A number g squared: [tex]g^{2}[/tex]
The sum of a number g squared and 4: [tex]g^{2}+4[/tex]
Is greater than or equal to: [tex]g^{2}+4\geq[/tex]
Greater than or equal to -5: [tex]g^{2}+4\geq-5[/tex]
Isolate [tex]g[/tex]:
[tex]g^{2}\geq -9[/tex]
Solve for [tex]g[/tex]:
[tex]\sqrt{g^{2}}\geq \sqrt{-9}[/tex]
This^ looks bad because of the negative, but as I'll show you in the next step it can be split up and you will use the value [tex]i[/tex], or [tex]\sqrt{-1}[/tex].
[tex]g\geq \sqrt{9} \sqrt{-1}[/tex]
[tex]g\geq +/-3i[/tex]
