Answer:
A. [tex] y_1 = -m(x_2 - x_1) + y_2 [/tex]
Step-by-step explanation:
Given, slope formula = [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
To find an equivalent equation, let's make [tex] y_1 [/tex] the subject of the formula.
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Cross multiply
[tex] 1(y_2 - y_1) = m(x_2 -x_1) [/tex]
[tex] y_2 - y_1 = m(x_2 - x_1) [/tex]
Subtract [tex] y_2 [/tex] from both sides
[tex] y_2 - y_1 - y_2 = m(x_2 -x_1) - y_2 [/tex]
[tex] - y_1 = m(x_2 - x_1) - y_2 [/tex]
Divide both sides by -1
[tex] \frac{- y_1}{-1} = \frac{m(x_2 -x_1) - y_2}{-1} [/tex]
[tex] y_1 = -m(x_2 - x_1) + y_2 [/tex]
Mary has a \large 16\frac{1}{2} ounce bag of chocolate chips. She will only use \large \frac{1}{4} of the bag for decorating a cake. How many ounces will she use for decorating
Answer:
4 1/8 ounces
Step-by-step explanation:
Total bag of chocolate chips Mary has = 16 1/2 ounces
She will only use 1/4 of the bag for decorating a cake.
How many ounces will she use for decorating
Ounces used in decoration = 1/4 of 16 1/2
= 1/4 × 33/2
= (1*33)/(4*2)
= 33/8
= 4 1/8 ounces of chocolate chips
She will use 4 1/8 ounces of chocolate chips for decorating a cake
I need help. I have been searching for the answer but I cannot find the correct one. Elena rode her bike 2 miles in 10 minutes and 1 mile in 5. How many miles if it only took her 1 minute? Like how many miles would she have rode in 1 minute?
Answer:
0.2 miles
Step-by-step explanation:
From the above question:
2 miles = 10 minutes
Hence:
10 minutes = 2 miles
1 minute = x miles
Cross Multiply
10 minutes × x miles = 2 miles × 1 minute
x miles = 2 miles × 1 minute/10 minutes
x miles = 0.2 mile
Hence in 1 minute it would take her 0.2 miles

Sally rides her bike 164.45 miles in two weeks. She averaged 12.65 miles per hour each time she rode. How many hours did it take her to ride 164.45 miles?
Answer: It took 13 hours by her to ride 164.45 miles.
Step-by-step explanation:
Total distance = 164.45 miles
Average distance traveled = 12.65 miles per hour (speed)
[tex]Time = \dfrac{Distance}{Speed}[/tex]
[tex]Time = \dfrac{164.45}{12.65}=\dfrac{16445}{1265}\\\\=13\text{ hours}[/tex]
Hence, it took 13 hours by her to ride 164.45 miles.

Ulian pays $120 for soccer shoes that are on sale for 20% off from a specialty store. At a discount store, the same shoes cost $42 less than they cost at the specialty store. They are on sale for 61% off. Complete the proportions below. Highlight in yellow the sale price of the shoes at the discount store. Highlight in orange the original price of the shoes at the discount store.
Answer:
Sales price = $78
Original price = $61
Step-by-step explanation:
Ulian bought the shows for $120 at a specialty store. This discount store had it at $42 less. The price at the discount store is therefore:
= 120 - 42
= $78
The shoes at the discount store are 61% off and the discounted price is $78. Assume the original price is x. The original price will be:
x - (x * 61%) = 78
x - 0.61x = 78
0.39x = 78
x = 78/0.39
x = $200

Both company 1 and 2 charge $153.75 for cleaning 25 garment
Step-by-step explanation:
Equation 1
[tex]\frac{85.50-62.75}{10-5} =\frac{22.75}{5}=4.55[/tex]
y-62.75=4.55(x-5)
y-62.75=4.55x-22.75
c(n)=4.55x + 40
Equation 2
[tex]\frac{67.50-38.75}{10-5}=\frac{28.75}{5}=5.75[/tex]
y-38.75=5.75(x-5)
y-38.75=5.75x-28.75
c(n)=5.25x + 10
The system will be
f(x)=4.55x+40
g(x)=5.75x+10
30=1.2x
x=25
f(x) when x=25
f(x)=4.55x+40
f(25)=4.55(25)+40
f(25)=113.75+40
f(25)=153.75
Both company 1 and 2 charge $153.75 for cleaning 25 garments.

Find the measure of each acute angle. PLEASE HELP !!
Answer:
7x=42°
8x=48°
Step-by-step explanation:
Sum of all interior angles in a triangle=180°
90+8x+7x=180
90+15x=180
15x=180-90
15x=90
x=90/15
x=6
The measure of each acute angle is 42° and 48°.
what is an Acute angle?If an angle is less than 90 degrees, then it is called an Acute angle. Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.
Given there is a right triangle. since it's a right triangle angle one angle will always be 90 degrees.
Since the sum of all angles of any triangle is 180 degrees thus,
7x + 8x + 90 = 180
15x = 90
x = 6
since each acute angles were 7x and 8x
hence those angles would be 42 and 48 degrees.
therefore, Each acute angle is 42° and 48° in size.

[tex]m\angle 1=95^{\circ}[/tex]
Step-by-step explanation:
If we drew an auxiliary line parallel to line [tex]p[/tex] and line [tex]q[/tex] that intersects the vertex of [tex]\angle 1[/tex], we would form three angles, one of them being
The largest of these angles corresponds with the angle marked as [tex]148^{\circ}[/tex].
The angle on the bottom right corresponds with the angle next to the one marked as [tex]63^{\circ}[/tex]. Therefore, its measure is [tex]180-63=117^{\circ}[/tex].
Since there are [tex]360^{\circ}[/tex] in a circle, we can now write the following equation:

The way SkiffMacKinaw did this problem is the way it should be done. There is another way of doing it by extending both arms of <1 until they intersect p and q and solve the triangle hanging from p.
You then find the the angles of the triangle. The vertex angle is the supplement to <1.
