true or false, the ratios 4:10 and 8:20 are equivalent
PLEASE HELP IF I FAIL MY MOM IS GONNA-
Answer:
True
Step-by-step explanation:
If you multiply both 4 and 10 by two, you get 8 and 20
The ratios 4:10 and 8:20 are Equivalent.
What is ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
As, when the two ratios are equal after simplifying then they are equivalent ratio.
So, 4/10
= 2/5
and, 8/20
= 2/5
As, both ratios are giving equal value after simplifying.

(e) If f(x+3) = f(x) + f(5) then prove that: f(2)= 0 and f(5) = -f(-1)
Answer:
See below.
Step-by-step explanation:
f(x + 3) = f(x) + f(5) (Given) so:
f(2 + 3) = f(2) + f(5)
and f(2) = f(2 + 3) - f(5)
= f(5) - f(5) = 0.
f(-1) = f(-1 +3) - f(5)
= f(2) - f(5)
= f(-3)
So - f(-1) = f(3)
Also:
f(5) = f(x + 3) - f(x)
= f(x + 3 - x)
= f(3).
But f(3) = -f(-1) ( shown above),
So f(5) = -f(-1).

Identify the most precise name for the angle pair shown in the picture.
1. Adjacent Angles
2. Supplementary Angles
3. Vertical Angles
4. Linear Pair
5. Complementary Angles
Answer:
Complementary Angles
Step-by-step explanation:
Complementary angles are angles whos measures add up to 90 degrees! The angles in the picture can also be described as adjacent angles, because they share the same vertex.
So these angles are technically both complementary and adjacent, but they are more specifically, complementary.

It was -8°F in the morning. The temperature increased throughout the day, and in the afternoon, it was 11°F. How much did the temperature change?
Answer:
19
Step-by-step explanation
This is simple
I will teach you a simple technique
Count them, don't count the -8
-8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11
You are just subtracting, but instead counting.
I said not to count -8, because normally in subtraction, we normally don't count the number we are subracting.
for example
8 - 7 = 1
so counting technique
8 - 7, 6, 5, 4, 3, 2, 1
there are 7 numbers, if i didn't count the 8
so it is right.
hope you understand :-)
Jim is investing in the stock market. Jim is hoping to earn $2,000 in interest in order to take a trip to Mexico. Stock A earns 4% interest and Stock B earns 7% interest, and Jim has a total of $32,000 to invest. How much should he invest in each in order to earn $2,000 interest?
Given:
Total amount for investment = $32000
Rate of interest for Stock A = 4%
Rate of interest for Stock B = 7%
Jim is hoping to earn $2,000 in interest.
To find:
The amount of investments in Stock A and Stock B.
Step-by-step explanation:
Let amount of investments in Stock A = $x
Amount of investments in Stock B = $y
Total amount for investment = $32000
[tex]x+y=32000[/tex] ...(i)
Rate of interests in Stock A and Stock B are 4% and 7%. Total interests is $2000.
[tex]0.04x+0.07y=2000[/tex] ...(ii)
From (i) and (ii), we get
[tex]0.04x+0.07(32000-x)=2000[/tex]
[tex]0.04x+2240-0.07x=2000[/tex]
[tex]-0.03x=2000-2240[/tex]
[tex]-0.03x=-240[/tex]
Divide both sides by -0.03.
[tex]x=\dfrac{-240}{-0.03}[/tex]
[tex]x=8000[/tex]
Put x=8000 in (i).
[tex]8000+y=32000[/tex]
[tex]y=32000-8000[/tex]
[tex]y=24000[/tex]
Therefore, the amount of investments in Stock A and Stock B are $8000 and $24000 respectively.
Why would someone choose to use a graphing calculator to solve a system of linear equations instead of graphing by hand? Explain your reasoning
Answer:
A graphing calculator is more accurate than graphing by hand. If the slope and/or y-intercept is a fraction or decimal, it is more difficult to accurately graph by hand.

To find:
The interpretation for the given statement.
Solution:
We know that,
[tex]f(x)=y[/tex] ...(i)
Here, x is the input value and y is the output value.
We have,
[tex]f(3)=75[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]x=3,y=75[/tex]
It means, the output value of the function f(x) is 75 at x=3.

Answer:
x = 12 and y = 24 Can I get brainiiest
Step-by-step explanation:
We know (3x + 34) and (2x + 46) are vertical to each other so they equal the same measure. We will solve it like this.
3x + 34 = 2x + 46 (subtract 34 on each side)
3x = 2x + 12 (subtract 2x on both sides)
x = 12
Now plug in
3(12) + 34 = 2(12) + 46
36 + 34 = 24 + 46
70 = 70
Now all you have to do is do the other pair of angle
4y + 14 + 70 = 180 (we are using what we already know about 70)
(collect like terms)
4y + 84 = 180 (subtract 84 on both sides)
4y = 76 (divide by 4)
y = 24
(plug in)
4(24) + 14 = 6(24) - 34
96 + 14 = 144 - 34
110 = 110
x - y = 5 in slope intercept form
Step-by-step explanation:
Hey there!
Given;
x-y = 5
Slope intercept form: y = mx+c.
Now try to make it in y= mx+c form.
Take"-y" to right side and and 5 to left side.
x-5= y
Therefore, y = x-5

The work W required to move a particle from a far distance to within radius r of another particle varies jointly as the product of the two particles' charges q1 and q2 and inversely as the radius r. Write a formula that models this proportion. (Use k as the constant of variation.)
Answer:
W = kq1q2 / r
Step-by-step explanation:
W varies jointly as the product of q1 and q2 and inversely as radius r
Product of q1 and q2 = q1q2
W = (k*q1"q2) / r
W = kq1q2 / r
Where,
W = work
q1 = particle 1
q2 = particle 2
r = radius
k = constant of proportionality
The answer is W = kq1q2 / r
Using proportions, it is found that the formula is:
[tex]W = k\frac{q_1q_2}{r}[/tex]
Work varies jointly as the charges, thus, the charges are in the numerator.Inversely as the radius, thus, the radius is in the denominator.There is a constant of proportionality k, which multiplies the fraction;Then, the formula is:
[tex]W = k\frac{q_1q_2}{r}[/tex]

Step-by-step explanation:
When you are dividing exponents you subtract. So for this problem -8 - -4 = -8 + 4 = -4. This means that the new exponent would be -4.
When you have a negative exponent, the equation is a fraction. As an example x^-5 would be equal to 1/x^5. For this equation, since you know that the new exponent is -4, an equivalent equation would be 1/3^4.

Which of the following name an angle in the drawing?
Answer:

Step-by-step explanation:
Select all the equations where b=11b=11b, equals, 11 is a solution. Choose 2 answers: Choose 2 answers: (Choice A) A 2b=2112b=2112, b, equals, 211 (Choice B) B b+18=7b+18=7b, plus, 18, equals, 7 (Choice C) C 77=7b77=7b77, equals, 7, b (Choice D) D 9=b-29=b−29, equals, b, minus, 2 (Choice E) E 11=33\div{b}11=33÷b
Answer:
Step-by-step explanation:
We are to choose all the equation that evaluates b to be 11. The following equations are true;
77 = 7b
To get b, we will divide both sides by 7
77/7 = 7b/7
11 = b
b = 11
This shows that the equation is correct since b = 11
Also 9 = b-2
To get b, we will add 2 to both sides of the expression
9+2 = b-2+2
11 = b
b = 11
This shows that the equation is correct since b = 11
