Answer:
y = (1/3)x + 7
Step-by-step explanation:
Steps:
(y-y1)=m(x-x1) where m=slope
Using (x1,y1) is (-6,5):
1: (y-5)= (1/3)(x-(-6))
2: (y-5) = (1/3)(x+6)
3: y-5 = (1/3)x + 2 Distribute
4: y = (1/3)x + 7 Add 5 to both sides

Francesca and Irvin are painting the walls of their clubhouse. Working alone Francesca can paint the walls in 6 hours. Irvin can complete the same walls in 4 hours if working alone. How long will it take them, working together, to finish painting. Round your answer to the nearest hundredth is necessary.
Answer:
Step-by-step explanation:
Work finished by Francesca in one hour = 1/6
Work finished by Irvin in one hour = 1/4
Work finished by Francesca and Irvin in one hour = 1/6 +1/4
[tex]=\frac{4}{24}+\frac{6}{24}\\\\=\frac{10}{24}\\\\=\frac{5}{12}\\[/tex]
5/12 of the work is completed by both in an hour
Whole work will be completed in 1*12/5 =12/5 hours = 2 2/5 hours

Step-by-step explanation:

(x - (—— • x)) - — = 0
10 2
Simplify 1/2
1 9
(x - (— • x)) - — = 0
2 2
x = 9
Answer:
x = 9
Step-by-step explanation:
Firstly, you have to balance the equation.
Start by subtracting 0.5 from both sides. Remember, when solving algebraic equations such as this one, you use reverse PEMDAS, or SADMEP.
Now, you have 0.5x = 4.5
Now, for the next step: division. Divide both sides by 0.5, or in other words, multiply by 2.
x = 9

A triangle was dilated by a scale factor of 6. If sin a° = four fifths and segment DE measures 30 units, how long is segment EF?
triangle DEF in which angle F is a right angle, angle D measures a degrees, and angle E measures b degrees
15.5 units
24 units
30 units
37.5 units
Answer:
24 units
Step-by-step explanation:
From the description:
angle D measures a degreesopposite to angle D is side EFside DE (which measures 30 units) is the hypotenuse of the triangle.We also know that
sin(a) = 4/5
From definition:
sin(a) = opposite/hypotenuse
Replacing:
4/5 = EF/DE
EF = (4/5)*DE
EF = (4/5)*30 = 24 units
The length of the segment EF of the triangle DEF is 24 units.
Procedure - Determination of the resulting length after dilating a triangle by a scale factorIn the image attached below we summarize the triangle described in statement, by trigonometric relationship we find that the length of the segment EF is described by the following expression:
[tex]\sin a^{\circ} = \frac{EF}{DE}[/tex] (1)
If we know that [tex]DE = 30[/tex] and [tex]\sin a^{\circ} = \frac{4}{5}[/tex], then the length of the segment EF is:
[tex]EF = DE\cdot \sin a^{\circ}[/tex]
[tex]EF = 30\cdot \left(\frac{4}{5} \right)[/tex]
[tex]EF = 24[/tex]
The length of the segment EF of the triangle DEF is 24 units. [tex]\blacksquare[/tex]

Which function has a greater slope and y-intercept than the linear function represented in the table?
A) y=2x+8.5
B) y=3x+7.5
C) y=5x+6.5
D) y=10x+5.5
Answer:
B) y=3x+7.5
Step-by-step explanation:
The equation of the data in the table can be obtained by using any two points.
We will use points (3, 13) and (5,17)
The slope - intercept form is:
y = mx + bWe find the slope as:
m = (17-13)/(5-3) = 4/2 = 2The equation becomes:
y = 2x + bTo find the value of b, the y -intercept is:
13 = 2*3 + b ⇒ b= 13 - 6 = 7So the equation is:
y = 2x + 7Now let's compare this with the optionsA) y = 2x + 8.5
The slope is 2, and y- intercept is 8.5It has same slope and greater y-interceptAnswer is noB) y=3x+7.5
The slope is 3, and y- intercept is 7.5It has greater slope and greater y-interceptAnswer is yesC) y=5x+6.5
The slope is 5, and y- intercept is 7.5It has greater slope but smaller y-interceptAnswer is noD) y=10x+5.5

Andre and his dad have been fishing for 2 hours. In that time, they have caught 9 blue gills and 1 yellow perch. How many total fish are there?
There are 10 total fish. We are looking at how many fish there are, so we need to add 9 + 1 to get our answer of 10 fish.
The next time Andre gets a bite, what kind of fish do you think it would be?
My prediction is that it will be a blue gill.
How do you know your prediction is more likely to happen?
9 out of 10 times, they have caught a blue gill. This is more probable than 1 out of 10.
Can you make any other predictions?
I would say that Andre will catch less yellow perches than blue gills. This is because the probability of catching a blue gill is greater than catching a yellow perch. I would also say that Andre will catch 5 fish per hour, since he caught 10 fish in 2 hours.

How much time did a person spend at the library over a month for them to spend 40 hours reading a book?
Round your final answer to the nearest whole number.
Answer:
The correct answer will be "1.60 hours".
Step-by-step explanation:
Within this test case, let's suppose that the bookstore had been closed on Sundays every other day while there were a total of 5 Sundays throughout the month of thirty days, thus effectively.
Months = 30
Number of sundays = 5
⇒ [tex]Effective \ working \ days = Months - Number \ of \ Sundays[/tex]
⇒ [tex]=30-5[/tex]
⇒ [tex]=25[/tex]
As we know, the total spend time will be 40 hours, then
⇒ [tex]Time \ spend \ each \ day = \frac{Total \ time \ spens}{Working \ days}[/tex]
On putting the estimated values, we get
⇒ [tex]=\frac{40}{30}[/tex]
⇒ [tex]=1.60 \ hours[/tex]

Parking for 4 hours costs $10. Parking for 5 hours costs $12. Is this a proportional relationship, and if so, what is the constant of proportionality?
Answer:
Not a Proportional Relationship ; No Constant of Proportionality
Step-by-step explanation:
Consider the first example, 4 hours of parking costs $ 10. From this we can derive the ratio 4 : 10, so that hours parked : fee for parking is a common ratio among the two examples, the other being 5 : 12;
[tex]4 : 10, Simplify\\2 : 5, Take As Fraction,\\Solution; 2 / 5ths\\[/tex]
[tex]5 : 12, Simplify\\( Can't Be Simplified Further ) - Take as Fraction,\\Solution; 5 / 12ths[/tex]
Considering that the fractions when compared are not similar, ( 2 / 5, and 5 / 12 ) they don't have a proportional relationship, and thus have no constant of proportionality
Solution; Not a Proportional Relationship

P=2l+2w. solve for w. show all steps. please
Answer:
Step-by-step explanation:
You need to get w on one side by itself.
Start out by subtracting 2l from both sides.
p−2l=2w.
Now since w is being multiplied by 2 we need to divided both sides (all terms) by 2.
w=p2−I
Answer:
W=P-L
Step-by-step explanation:
P=2L+2W
Subtract 2L from both sides.
P-2L=2W
Divide both sides by 2
P-L=W

^thank you and stay safe
^^I will also mark some one the brainiest who ever answers this ;)
Answer:
10/3 lawn
Step-by-step explanation:
2/3 of a lawn in 1/5 hour
-> 1 hour cab mow = 2/3(lawn) ÷ 1/5(hour)* 1(hour)
= 10/3 = 3,666666667 lawns
Answer:
maria can mow 3 lawns
Step-by-step explanation:
if it takes 1/5 of an hour to mown 2/3 of one lawn
60 divide by .2 = 12
that means it takes 12 miuntes to mown 2/3 of a lawn, so it takes 6 minutes for each 1/3
so 12+6= 18 minutes for one whole lawn
so 18 plus 18 equals 36
so 36 minutes for 2 lawns
then add another 18 minutes and you'll get 54 minutes. That's almost a whole hour
so Maria can mown 3 lawns
( if im wrong, im sorry i tried)
Write the equation of the line that passes through the points (-1,-5) and (2,4).
Answer:
y=3x+1
Step-by-step explanation:
First, we have to find the slope. [tex]\frac{4-(-5)}{2-(-1)}[/tex] This comes out to 9/3. This becomes 3. Now we need to find the y-intercept. Now write out how to find the answer. 4=3(2)+b. 4=3+b. Subtract 3 from both sides to get 1=b. Now write out the equation. y=3x+1

m∠1 = (4x + 9)° and m∠2 = (x − 14)° in the given figure. Find x. answers: 19 7 8 37
Answer:
x = 19
Step-by-step explanation:
∠ 1 + ∠ 2 = 90° ( corresponding angle ), substitute values
4x + 9 + x - 14 = 90
5x - 5 = 90 ( add 5 to both sides )
5x = 95 ( divide both sides by 5 )
x = 19
The value of variable x is,
⇒ x = 19
We have to given that;
Measure of angles are,
m∠1 = (4x + 9)°
And, m∠2 = (x − 14)°
Now, We can see that,
Measure of angle 1 and 2 are complementary angle.
Hence, We get;
⇒ m ∠1 + m ∠2 = 90°
Substitute all the values, we get;
⇒ (4x + 9) + (x - 14) = 90
⇒ 5x - 5 = 90
⇒ 5x = 90 + 5
⇒ 5x = 95
⇒ x = 95 / 5
⇒ x = 19
Thus, The value of variable x is,
⇒ x = 19
