Solve by substitution
y = -5x
y + 4x = -1
Explain PLZ
Answer:
x= 1
Step-by-step explanation:
The value of y = -5x
Plug it in the equation of y + 4x = -1
So it becomes, -5x + 4x = -1
Combine like terms which are -5x and 4x which equals to -x
Eliminate the negative sign because x cannot be negative. Apply that to -1. It becomes 1.
Hope you find this helpful!
Answer:
Step-by-step explanation:
Equation 1: y = -5x
Equation 2: y + 4x = -1
Step 1. Substitute y in equation 2 using equation 1
You would get, -5x + 4x = -1
Step 2. Combine like terms
-x = -1
Step 3. Cross out the negatives
x = 1
Step 4. Substitute x in Equation 1 to get y
y = -5(1)
y = -5
Hope this helps :)

What is the permutation and combination?Permutation and Combination form the principles of counting and they are applied in various situations.
A permutation is a count of the different arrangements which can be made from the given set of things. In permutation the details matter, as the order or sequence is important.
Here given that,
A blood bank needs 5 people to help with a blood drive. 10 people have volunteered.
Here, We get;
The different groups of 5 can be formed from the 10 volunteers is,
⇒ ¹⁰C₅
⇒ 10! /5! 5!
⇒ 10×9×8×7×6 / 5×4×3×2

Answer:
[tex]tan(A) = \frac{4}{3}[/tex]
Step-by-step explanation:
Here we see tan(B) has opposite side of 12 and adjacent of 9
using the formula:
[tex]tan(A) = \frac{opposite }{adjacent}[/tex]
[tex]tan(A) = \frac{12}{9}[/tex]
[tex]tan(A) = \frac{4}{3}[/tex]
Answer:
[tex]\textsf{tan(A)}=\frac{4}{3}[/tex]
Step-by-step explanation:
The trig ratio for tan is: [tex]\textsf{tan}(x)=\mathsf{\frac{O}{A}}[/tex] where
[tex]x[/tex] is the angle O = side OPPOSITE to the angleA = side ADJACENT to the angleFor angle A:
O = 12
A = 9
[tex]\implies \textsf{tan(A)}=\frac{12}{9}\\\\\implies \textsf{tan(A)}=\frac{4}{3}[/tex]

An ellipse has vertices along the major axis at (0, 8) and (0, –2). The foci of the ellipse are located at (0, 7) and (0, –1). What are the values of a, b, h, and k, given the equation below? a = b = h = k =.
The values of a, b, h, and k, given the equation below;
[tex]\rm \dfrac{(x-h)^2}{b^2}+\dfrac{(x-k)^2}{a^2}=1\\\\ \dfrac{(x-0)^2}{3^2}+ \dfrac{(x-3)^2}{5^2}=1[/tex]
Given
An ellipse has vertices along the major axis at (0, 8) and (0, –2).
The foci of the ellipse are located at (0, 7) and (0, –1).
EllipseIt can be seen that the major axis is parallel to the y axis.
The major axis points are;
(h, k +a) = (0, 8)
(h, k -a) = (0, -2)
Here, k + a = 8
k - a = -2
Subtracting the equations;
k + a - k + a = 8 + 2
2a = 10
a = 10/2 = 5
The foci are;
(h, k +c) = (0, 7)
(h, k -c) = (0, -1)
Here, k + c = 7
k - c = -1
Subtracting the equations;
k + c -k + c = 7+ 1
2c = 8
c = 8/2 = 4
The foci are given by;
[tex]\rm c^2=a^2-b^2\\\\b=\sqrt{a^2-c^2} \\\\b = \sqrt{5^2-4^2}\\\\b = \sqrt{25-16} \\\\ b =\sqrt{9}\\\\ b=3[/tex]
The equation is;
[tex]\rm \dfrac{(x-h)^2}{b^2}+\dfrac{(x-k)^2}{a^2}=1\\\\ \dfrac{(x-0)^2}{3^2}+ \dfrac{(x-3)^2}{5^2}=1[/tex]

Napoleon's route through the alps involved a climb of 6km and a descent of 4km. His army travelled twice as fast downhill as it did uphill, the whole journey took 8 hours. How long did it take to reach the top?
Answer:
6 hours.
Step-by-step explanation:
since that is true we can use trial and error. if every km took an hour it would take six hours up and 4 hours down but they said they were twice as fast going down so that means it would take 2 hours going down. 6 add 2 is 8 which is our total meaning that 6 hours is the right answer

Consider the information in the previous questions (Henry only has quarters, nickels, dimes and pennies). Is it mathematically possible for Henry to have exactly 23 pennies if he has a total of $2.41? Defend your conclusion with an equation for the sum of the coins and two or more complete sentences explaining your conclusion.
Answer:
NoStep-by-step explanation:
The total amount is $2.41.
If the are 23 pennies, then the amount excluding the pennies is:
$2.41 - $0.23 = $2.18This amount comprises quarters, nickels and dimes.
Each of them is multiple of 5:
Quarter = $0.25Nickel = $0.05Dime = $0.10Any amount made by the combinations of these has to be multiple of 5 cents. But the sum is $2.18, which is not multiple of 5 cents.
It means Henry can't make it.

Answer:
1a) A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound.
1b)An ionic compound formed by acid-base reactions and without those ions is called a salt. Water is definitely one of the most important inorganic compounds to all living things. It is a compound comprised of two hydrogen atoms and one oxygen atom.
The four major classes of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
2a)Regulates body temperature. Moistens tissues in the eyes, nose and mouth. Protects body organs and tissues. Carries nutrients and oxygen to cells.
2b)If a cell is seriously deprived of water,
this lack of water would most likely affect
the cell's enzymes because:
• The cytoplasm and plasma
membrane would not function
properly
Both the plant and animal cell needs
water in order to perform their basic
functions which include transport of
materials, waste distribution, production
of genetic information, and many more.
As a result of this, we can see that there
would be a serious problem if any
of these cells are deprived of water
which would lead to the cytoplasm and
plasma membrane to partially shut
down because they would not be able to
engage in protein synthesis and other
important functions.
3a)Carbohydrates provides energy rich for organic compounds made of elements carbon, hydrogen and oxygen. The lipids contain the element nitrogen. The carbohydrates contain the only elements carbon, hydrogen, and oxygen.
3b)Organic nitrogen occurs in many forms, including amino acids, proteins, nucleic acids, nucleotides, and urea.
3c)A carbohydrate has only Carbon, Hydrogen and Oxygen, with the hydrogen and oxygen in the ratio 2:1. A protein is made of amino acids. ... So without nitrogen atoms the compound can not be a protein.

Answer:
a. length: 20-2x; width: 12-2x; height: x
b. V = 4x^3 -64x^2 +240x
c. cubic trinomial
d. 262.7 cubic inches maximum for a 2.4 inch square
e. 15 × 7 × 2.5 inches for 262.5 in³ volume
Step-by-step explanation:
a.If the square cut from each corner has side length x, the dimensions are ...
height: xwidth: 12 -2xlength: 20 -2x__
b.The volume is the product of length, width, and height.
V = LWH
V = (20 -2x)(12-2x)(x) = 4(x-10)(x-6)x = 4(x^2 -16x +60)x
V = 4x^3 -64x^2 +240x
__
c.The volume function is a cubic trinomial.
__
d.The maximum volume will be found where the derivative of the volume function is zero.
V' = 12x^2 -128x +240 = 0
x^2 -32/3x +20 = 0 . . . . divide by 12
(x -16/3)^2 = 76/9 . . . . . complete the square
x = (16 -√76)/3 ≈ 2.4 . . . . size of the square
V = 4(2.4)(10 -2.4)(6 -2.4) ≈ 262.7 . . . cubic inches
The maximum box volume is about 262.7 cubic inches when the square is about 2.4 inches on each side.
__
e.A graphing calculator shows there to be two solutions for a volume of 262.5 cubic inches. The rational solution is x = 2.5 inches. The box dimensions would be ...
length = 20 -2(2.5) = 15 incheswidth = 12 -2(2.5) = 7 inchesheight = 2.5 inchesA wooden building has the shape of a rectangular pyramid. The buildings base is 100 meters long and 50 meters wide. The height of each triangular face is 40 meters. How much wood was used to make the entire building?
