Answer:
y-10=5(x+2)
Step-by-step explanation:
y-y1=m(x-x1)
y-10=5(x-(-2))
y-10=5(x+2)
Answer:
y - 10 = 5(x + 2)Step-by-step explanation:
The Point-Slope form of equation of a line with slope of "m" and passing through point (x₁, y₁) is: y - y₁ = m(x - x₁)
m = 5
x₁ = -2
y₁ = 10
Therefore the equation:
y - 10 = 5(x + 2)Tell whether (2,0) is a solution of y=7x+ 2.
Answer:
No
Step-by-step explanation:
7x2=14, 14+2=16, 16 is not 0.
A number between 10 and 20 is both a foctor of 60 and
a multiple of 6.
What is the number?
Answer:
12
Step-by-step explanation:
List out factors of 60 =
1 x 60 = 60
2 x 30 = 60
3 x 20 = 60
4 x 15 = 60
5 x 12 = 60
6 x 10 = 60
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60 are factors of 60.
List out multiples of 6 from 10 to 20.
12 and 18.
Since 12 is seen on one of the factors of 60 and a multiple of 6 between 10 and 20, the answer is 12.

A shop owner increases some prices by 50%.
This is the same as:
choose one
multiplying the original price by 0.5, 1.5, 2.5 or 150?
The another way is same as;
Multiplying by 0.5 with original price.
Here,
A shop owner increases some prices by 50%.
We have to find another method to find same condition.
What is the percentage?
A relative value indicating hundredth parts of any quantity is called the percentage.
Now,
A shop owner increases some prices by 50%.
Let the original price is x.
Then, The increase value = x * 50% = x * 50/100 = 0.5x
Hence, To find the increase value we have to multiply by 0.5 with original price.

Will give brainliest for full answer
Answer:
x = 3 and x = 8
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, then
WA = DR , substitute values
12x - 9 = 5x + 12 ( subtract 5x from both sides )
7x - 9 = 12 ( add 9 to both sides )
7x = 21 ( divide both sides by 7 )
x = 3
------------------------------------------------------
The diagonals of a parallelogram bisect each other, then
QS = [tex]\frac{1}{2}[/tex] QT , that is
8x - 14 = [tex]\frac{1}{2}[/tex] × 100 = 50 ( add 14 to both sides )
8x = 64 ( divide both sides by 8 )
x = 8
Answer:
x = 3 and x = 8

a. How far is the spot on the beach from the parking lot?
b. How far will he have to walk from the parking lot to get to the refreshment stand?
Show work please.
The altitude of the right triangle is the geometric mean of the 2 parts of the side it separates.
a. The answer would be sqrt(18*32)=24
The question to the second question can be answered by using the Pythagorean theorem.
32^2+24^2=1600=40^2
b. The answer would be sqrt40^2=40
The beach, the parking lot and the refreshment stand are illustrations of similar triangles.
The distance between the spot and the parking lot is 24 mThe distance between the refreshment stand and the parking lot is 40 m(a) The distance between the spot and the parking lot
Represent this distance with d.
So, the equivalent ratio is:
[tex]\mathbf{32:d = d : 18}[/tex]
Express as fractions
[tex]\mathbf{\frac {32}d = \frac{d}{ 18}}[/tex]
Cross multiply
[tex]\mathbf{d \times d = 32 \times 18}[/tex]
[tex]\mathbf{d^2 = 576}[/tex]
Take square roots
[tex]\mathbf{d = 24}[/tex]
Hence, the distance between the spot and the parking lot is 24 m
(b) The distance between the refreshment stand and the parking lot
Represent this distance with d.
Using Pythagoras theorem we have:
[tex]\mathbf{d^2 = 32^2 + 24^2}[/tex]
[tex]\mathbf{d^2 = 1600}[/tex]
Take square roots
[tex]\mathbf{d = 40}[/tex]
Hence, the distance between the refreshment stand and the parking lot is 40 m

the mean temperature for the first 4 days in January was - 4 degrees the mean temperature for the first 5 days in January was - 6
degrees what was the temperature on the 5th day
Answer: The temperature on the 5th day is -14 degrees.
Step-by-step explanation:
If we have a set of N values:
{x₁, x₂, x₃, ..., xₙ}
The mean value of this set is:
M = (x₁ + x₂ + ... + xₙ)/N
Now, we know that the mean temperature for the first 4 days of January is -4°
Then if the temperatures for the first four days are {T₁, T₂, T₃, T₄}
We have:
M₄ = (T₁ + T₂ + T₃ + T₄)/4 = -4°
Where we can replace (T₁ + T₂ + T₃ + T₄) by K
Then:
K/4 = -4°
K = -4°*4 = -16°
Is the sum of the temperatures for the first four days.
Now when we consider the first 5 days, the mean is -6°, and let's define T₅ as the temperature of the fifth day, then we get:
M₅ = -6° = (T₁ + T₂ + T₃ + T₄ + T₅)/5
And we know that:
(T₁ + T₂ + T₃ + T₄) = K = -16°
We can replace that in the above equation to get:
M₅ = (-16° + T₅)/5 = -6°
Now we can solve this for T₅
(-16° + T₅) = 5*(-6°) = -30°
T₅ = -30° + 16° = -14°
T₅ = -14°
The temperature on the 5th day is -14 degrees.

Answer:
x = 12, 6
Step-by-step explanation:
Factor using the AC method.
Consider the form x² + bx + c. Find a pair of integers whose product is c and whose sum is b . In this case, whose product is 72 and whose sum is -18.
-12, -6
Write the factored form using these integers.
(x - 12)(x - 6) = 0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
x - 12 = 0, x = 12
x - 6 = 0, x = 6

a trapezoidal prism has a volume of 1260 cm^3. the height of the prism is 18 cm while the bases of the trapezoid are 12 cm and 8cm. Sketch the prism and find the height of the trapezoidal base
Answer:
7 cmStep-by-step explanation:
Volume of the prism is the product of its base area and height
V = AHV = 1260 cm³H = 18 cmFind base area:
A = 1260/18 = 70 cm²Area of the trapezoid:
A = 1/2(b₁ + b₂)hSubstitute given values and solve for h:
70 = 1/2(12 + 8)h70 = 10hh = 70/10h = 7 cmFind area of base

If , then what is mto the nearest degree?
Answer:
70 degrees
Step-by-step explanation:
If cosm<A = 342/1000, we are to find the value of a
Take arccos of both sides
cosm<A = 342/1000
cosm<A = .342
arccos(cosm<A) = arccos(0.342)
m<A = arccos(0.342)
m<A = 70 degrees
Hence the measure of m<A is 70 degrees

Answer:44
Step-by-step explanation:subtract 55-11 which would equal L
Answer:
If you are multiplying L*W the answer would be 5 because w=11 ok and we don't know what L is but we know what A is and a=55 so you have to think what do we multiply 11 by to get 55 weel it's 5 so that's how we would know it's 5 IF you were multiplying. now if you just adding L+W that answer would be 44 because 55-11=44
