Step-by-step explanation:
what is the equation of the line that passes through the point (-5,2) and has a slope of 4/5
Answer:
y = [tex]\frac{4}{5}[/tex] x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = [tex]\frac{4}{5}[/tex] , then
y = [tex]\frac{4}{5}[/tex] x + c ← is the partial equation
To find c substitute (- 5, 2 ) into the partial equation
2 = - 4 + c ⇒ c = 2 + 4 = 6
y = [tex]\frac{4}{5}[/tex] x + 6 ← equation of line
Answer:
Below.
Step-by-step explanation:
Use the point-slope form of a straight line.
y - y1 = m(x - x1)
Here m = 4/5, x1 = -5 and y1 = 2, so
y - 2 = 4/5(x - -5))
y - 2 = 4/5 x + 4
y = 4/5x + 6 is the answer in slope-intercept form.
Standard form:
Multiply through by 5:
5y = 4x + 30
4x - 5y = -30 is the answer in standard form.
Which set of angles is complementary?
Answer:
angles ECF and BCF
Step-by-step explanation:
Santiago is trying to earn experience points in his newest game. He knows that finding
gophers will get him the most points. His number of experience points after his first attempt
can be represented by the linear equation - 24x + 2y = 900, where y represents Santiago's
total number of experience points and x represents the number of gophers he finds.
What is the slope of the line? What does this represent?
F The slope is 12; he earns 1 point for every 12 gophers he finds.
G The slope is 450; he earns 1 point for every 450 gophers he finds..
# The slope is 12; he earns 12 points for each gopher he finds.
J The slope is 450; he earns 450 points for each Igopher he finds.

Directions: Find the value of x.
Round angle measures to the nearest degree.
Given:
The figure of a right triangle.
To find:
The value of x.
Solution:
In a right angle triangle,
[tex]\sin \theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]
In the given right triangle,
Hypotenuse = 15
Perpendicular = 12.5
Now,
[tex]\sin x^\circ=\dfrac{12.5}{15}[/tex]
[tex]\sin x^\circ=0.83333[/tex]
[tex]x^\circ=\sin^{-1}0.83333[/tex]
[tex]x^\circ =56.442345^\circ[/tex]
[tex]x\approx 56[/tex]
Therefore, the equation used to find x is [tex]\sin x^\circ=\dfrac{12.5}{15}[/tex] and the value of x is 56.

- 4/9 times - 5/8 in fractions.
Answer:
5/8 x 4/9 = 20/72 as simplified as 5/18 in fraction form. 5/8 x 4/9 = 0.2778 in decimal form.
Step-by-step explanation:
The product of -4/9 and -5/8 is 5/18.
Given are two negative fractions -4/9 and -5/8, we need to find their product,
To find the product of two negative fractions, you can multiply their numerators together and their denominators together, while keeping the negative sign.
Let's find the product of -4/9 and -5/8:
Product = (-4/9) x (-5/8)
To calculate the product, multiply the numerators and denominators:
Product = (-4 x -5) / (9 x 8)
Simplifying the multiplication:
Product = 20 / 72
Now, you can simplify the fraction by finding the greatest common divisor (GCD) of the numerator and denominator, which in this case is 4:
Product = (20/4) / (72/4)
= 5/18
Therefore, the product of -4/9 and -5/8 is 5/18.

Luis plans to purchase some new baseball bats and gloves before spring training begins. Luis wants to buy the same bats and gloves he purchased last spring, but he can’t remember the price of each item. Luis recalls making two purchases last spring, each totaling $135 and both tax exempt. The first purchase was for a glove and three bats. The second purchase was for two gloves and a bat. If the current prices of these items are the same as last spring, how much will Luis pay this spring for three gloves and four bats?
Answer:
Luis will pay for three gloves and four bats = $ 270
Step-by-step explanation:
Let the bats be represented by b and gloves by g, then according to the given conditions
3b+ g= $135----equation 1
b+ 2g= $135------equation 2
Subtracting equation 2 from eq. 1 gives
3b+ g= $135----equation 1
-b -2g= -$135------equation 2
2b -g = 0 --------- equation3
2b-g= 0
or 2b= g------ equation4
This means price of 2 bats is equal to price of 1 glove.
Putting value of g in eq. 1 from eq. 4
3b+ 2b= $ 135
5b= $135
b= 135/5= 27
Price of 1 bat = $ 27 and price of 1 glove= 2*27= $54
Luis will pay for three gloves and four bats
= 54*3 + 4*27
= 162+ 108
= $ 270

What does A equal: 3(6a+12)=9
Answer:
a = -3/2
Step-by-step explanation:
3(6a+12)=9
Divide each side by 3
3/3(6a+12)=9/3
6a+12 = 3
Subtract 12 from each side
6a+12-12 = 3-12
6a = -9
Divide by 6

Oliver is performing an experiment by spinning a metal weight around on the end of a nylon thread. How far does the metal weight travel if it
completes 10 revolutions on the end of a 0.88 m thread?
Give your answer correct to one decimal place.
Answer:
27.7m
Step-by-step explanation:
Step 1
We find the Circumference of the nylon thread.
The formula = 2πr
The diameter of the thread = 0.88m
Radius = Diameter/2
= 0.88m/2
= 0.44m
Circumference = 2 × π × 0.44m
= 2.7646015352m
Approximately = 2.765m
Step 2
We calculate the distance
Number of revolutions = 10
Therefore, the Distance or how far the metal weight can travel =
Circumference of the wheel × Number of revolutions
= 2.765m × 10
= 27.65m
Approximately to 1 decimal place = 27.7m

help me pls, question is on the picture
Answer:
I just learned this about a few weeks ago I hope this helps.
Step-by-step explanation:
Since it's cosine you're only looking at Adjacent and the hypotenuse which the adj is 20 and the hyp is 25 so since cosine is adj/hyp you do 20/25 then simplify it to 20/25 divide both by 5 so it's simplified to 4/5.
Then you do Cos-1(4/5)=36.869 which is rounded to the tenth 36.9 but rounded to the hundredth 36.87.

At Wegmans a 12 pack of paper towels costs $15.72. At Tops a 10 pack of paper towels cost $13.35. Which store has the better buy? What is the difference in unit prices?
Answer:
Wegman's, roughly 3 cents
Step-by-step explanation:
Divide the price by the number of paper towels in the pack to get the unit price.
$15.72/12= $1.31
$13.35/10= $1.335, round since it's money, $1.34
$1.34-$1.31= $0.03 or 3 cents
Wegmans has the better buy, as their unit price is lower.
The difference in unit prices between the two stores is $0.03 per paper towel.
To determine which store has the better buy, we need to compare the unit prices of paper towels at both Wegmans and Tops.
The unit price is the cost per paper towel.
For Wegmans:
Cost of 12 pack of paper towels = $15.72
Number of paper towels in the pack = 12
Unit price at Wegmans = Total cost / Number of paper towels
Unit price at Wegmans = $15.72 / 12 = $1.31 per paper towel
For Tops:
Cost of 10 pack of paper towels = $13.35
Number of paper towels in the pack = 10
Unit price at Tops = Total cost / Number of paper towels
Unit price at Tops = $13.35 / 10 = $1.34 per paper towel
Now, we compare the unit prices:
At Wegmans, the unit price is $1.31 per paper towel.
At Tops, the unit price is $1.34 per paper towel.
The store with the lower unit price has the better buy.
In this case, Wegmans has the better buy, as their unit price is lower.
To find the difference in unit prices:
Difference in unit prices = Unit price at Tops - Unit price at Wegmans
Difference in unit prices = $1.34 - $1.31 = $0.03 per paper towel
So, the difference in unit prices between the two stores is $0.03 per paper towel.
