Solve for 2x-4y =20
X=4
Answer:
So -1-9= -10
And if x =4 then 2(4)-4y=20
Y= -3
Step-by-step explanation:
2(4)-4y=20
8-4y=20
-4y=12
y=-3
Answer:
-1 - 9 = -10 &
y = -3
Step-by-step explanation:
2x - 4y = 20
2(4) - 4y = 20
8 - 4y = 20
-4y = 12
y = -3

Convert the equation to vertex form.
y = x2 – 8x + 10
Answer:
Step-by-step explanation:
y = (x² - 8x) + 10
Complete the square
coefficient of the x term: -8
divide it in half: -4
square it: (-4)² = 4²
use 4² to complete the square and keep the equation balanced:
y = (x²-8x + 4²) - 4² + 10
y = (x-4)² - 6
Answer:
y = (x - 4)² - 6
Step-by-step explanation:
use the 'completing the square' method:
x² - 8x + 10 = 0
x² - 8x + 16 = -10 + 16
(x - 4)² = 6
y = (x - 4)² - 6
Which value is the solution to the equation 20=y+12 ? ( use substitution to find solutions to equations.)
Answer:
8 = y
Step-by-step explanation:
In order to find a solution to an algebraic equation such as this one we simply need to isolate the variable. We do this by applying the opposite operation to each side in order to get rid of the other factors and get the variable alone. Like so...
20 = y + 12 ... we need to subtract 12 from both sides to get rid of the 12 on the right side with the variable y.
20 - 12 = y + 12 - 12
8 = y
Finally, we can see that the value of the variable y is 8

Question 7: Which type of probability distribution best describes the problem
Answer:
Hypergeometric distribution
Step-by-step explanation:
The hypergeometric distribution is the type of geometric distribution that best describes this problem.
The hypergeometric distribution is a distribution function where weake selections from 2 groups and by doing so no members of the groups are replaced. The 2 groups are the two sections of probability and statistics.
if i buy 4m of cloth at N1.75 per m how much change shall I receive out of N10.00
Answer:
$3
Step-by-step explanation:
4 x 1.75 = $7
$10 - $7 =
$3
Hope that helps!
The amount of change you will receive after buying the cloth is N3.00.
What is function? Differentiate between equation and expression? function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that you bought 4m of cloth at N1.75 per meter.
The amount of change you will receive after buying the cloth is -
N10 - N(1.75 x 4)
N{10 - 1.75 x 4}
N{10 - 7}
N3.00
Therefore, the amount of change you will receive after buying the cloth is N3.00.

will received a 2% increase in pay, He was making $1,190/biweekly.
a. How much was his raise?
b. How much is he making now?
Answer:
A: His raise was $23.8
B: He is making $1213.8
Step-by-step explanation:
Do 1190 divided by 100 and your answer will be
11.9 which is 1%, then do (11.9 + 11.9) + 1190 which will equal 1213.8
a. Will's raise was the amount of $23.80. b. Will is now making $1,213.80 biweekly.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If Misha obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.
Will receive a 2% increase in pay, He was making $1,190/biweekly.
a. Will's raise was $23.80. This can be calculated by multiplying his original biweekly payments of $1,190 by 2% (0.02).
b. Will is now making $1,213.80 biweekly. This can be calculated by adding his raise of $23.80 to his original biweekly payments of $1,190.

One of the legs of a right triangle measures 4 cm and the other leg measures 19 cm. Find the measure of the hypotenuse. If necessary, round to the nearest tenth.
Answer:
A2 + B2 = C2, so 4 squared + 19 squared = C2, 16 + 361 = 377. 377's square root is 19.4.
Step-by-step explanation:
The measure of the hypotenuse is 19.4 cm.
Given that, one of the legs of a right triangle measures 4 cm and the other leg measures 19 cm.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
Let the measure of the hypotenuse be x.
Using Pythagoras theorem,
x² = 4² + 19²
⇒ x² = 16 + 361
⇒ x² = 377
⇒ x = √377
⇒ x = 19.4 cm
Therefore, the measure of the hypotenuse is 19.4 cm.

Answer:
[tex]\theta = 4.8^\circ[/tex]
It is possible
Step-by-step explanation:
Given
See attachment for the construction
Solving (a): The minimum angle
This is calculated as thus:
[tex]tan(\theta) = \frac{Opposite}{Adjacent}[/tex]
[tex]tan(\theta) = \frac{15}{180}[/tex]
[tex]tan(\theta) = 0.0833[/tex]
Calculate [tex]\theta[/tex]
[tex]\theta = tan^{-1}(0.0833)[/tex]
[tex]\theta = 4.761[/tex]
[tex]\theta = 4.8^\circ[/tex] --- approximated
Solving (b):
First; calculate the height of the building using the following equivalent ratio.
[tex]h : 420 = 15 : 180[/tex]
Where h is the height of the building
[tex]\frac{h }{ 420 }= \frac{15 }{ 180}[/tex]
[tex]h= \frac{15 }{ 180}*420[/tex]
[tex]h= \frac{15*420 }{ 180}[/tex]
[tex]h= \frac{6300}{ 180}[/tex]
[tex]h= 35[/tex]
This means that it is possible that the builder builds a 32 feet high building
From the picture attached,
Angle of depression = Angle of elevation (θ) [Alternate angles]
Apply tangent rule in ΔCDP,
[tex]\text{tan}\theta=\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
[tex]\text{tan}\theta=\frac{CD}{DP}[/tex]
[tex]=\frac{15}{180}[/tex]
[tex]=\frac{1}{12}[/tex]
[tex]\theta=\text{tan}^{-1}(0.08333)[/tex]
[tex]\theta=4.76^\circ[/tex]
Similarity of two triangles:If two triangles are similar, their corresponding sides will be proportional.Use this property to get the height of the new building.
Since, ΔABP and ΔCDP are the similar triangles, their corresponding sides will be proportional.
[tex]\frac{AB}{BP}=\frac{CD}{DP}[/tex]
[tex]\frac{AB}{420}=\frac{15}{180}[/tex]
AB = [tex]\frac{420\times 15}{180}[/tex]
= 35 feet
But the construction for a new building has a maximum height restriction of 32 feet.
And the height of the building is more than the restricted height.
Therefore, it is not possible for the builder to have a rooftop patio with a view of the ocean.

Answer:Melissa's mom, dad, and brother each drove 312miles, 168miles and 0 miles respectively
Step-by-step explanation:
If Mellisa's dad drove 35% of the way
and Melissa's mum drove 65% of the way,
Then
Melissa's brother did not drive at all because
Miles covered by her dad = 35% x 480 = 0.35 x480= 168 miles
Miles covered by her mum= 65% x 480 = 0.65 x 480=312miles
