What is the domain of the
quadratic parent function y=x2?

Answer:

The correct answer is 63k + 42m.

Step-by-step explanation:

To solve this problem, we must remember how to use the distributive property.  The distributive property tells us that if we have a coefficient outside of the parentheses (in this case, 7), we can multiply each term inside the parentheses by this coefficient and add the products together.  This is modeled below:

7(9k + 6m)

(7*9k) + (7 * 6m)

63k + 42m

Therefore, the correct answer is 63k + 42m.

Hope this helps!

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{8 = 8}}}}}[/tex]

Option C is the correct option

Step-by-step explanation:

[tex] \sf{8(2 \div 2) = 2(8 \div 2)}[/tex]

Left hand side ( L.H.S )

⇒[tex] \sf{8(2 \div 2)}[/tex]

Divide 2 by 2

⇒[tex] \sf{8 \times 1}[/tex]

Multiply the numbers : 8 and 1

⇒[tex] \sf{8}[/tex]

Again, Right hand side ( R.H.S )

[tex] \sf{2(8 \div 2)}[/tex]

Divide 8 by 2

⇒[tex] \sf{2 \times 4}[/tex]

Multiply the numbers : 2 and 4

⇒[tex] \sf{8} [/tex]

∴ 8 = 8

Answer:

wat number put the value there

The required sum of the number m and the number after it 2m + 1.

Given that,
To determine the sum of the number m and the number after it.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Let the number m and the number after m is m+1
Now the sum = m + m + 1
                      = 2m + 1

Thus, the required sum of the number m and the number after it 2m + 1.

Answer:

4 and 12

Step-by-step explanation:

Answer:

S varies partly directly as M and Q.

S=C.

S=KMQ+C.

For the first one...

speed=80,m=220,Q=30.

80=K20×30+C.

80=600K+C......(I).equation one.

For the second one....

speed=60,m=300,Q=40.

60=K300×40+C.

60=12000K+C.....(ii). equation two.

Minus eqtn(I) from eqtn(ii).

80=600K+C.

- 60=12000K+C.

K=0.01754~0.018.

Substitute K=0.018 into eqtn(I).

80=600K+C

80=600×0.018+C.

80=10.8+C.

C=80-10.8=69.2.

The relation is S=0.018MQ+69.2

when speed is 100 and mass is 250 find the volume.

100=0.018×250×Q+69.2.

100=4.5Q+69.2.

4.5Q=100-69.2

4.5Q=30.8.

Q=30.8/4.5.

Q=6.8~7litres.

Answer:

Step-by-step explanation:

Since ∠A and ∠B are complementary angles their angles sum up to 90°.

In order to find ∠B add both ∠A and ∠B and equate them to 90° and solve for ∠B

That's

∠A + ∠B = 90

42 + ∠B = 90

∠B = 90 - 42

We have the final answer as

Hope this helps you

Answer:

∠B = 48°

Step-by-step explanation:

A Complementary angles are total of 90°

If the measure of ∠A is 42°, find the measure of ∠B:

∠A + ∠B = 90°

42° + ∠B = 90°

∠B = 90° - 42°

∠B = 48°

Step-by-step explanation:

Hyperbola is the conic section described by the equation 4x² = 10 +y²

A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped.

To identify the type of conic section from an equation whether it is circle, or ellipse a let suppose the equation as,

Ax²+By²+Cx+Dy+E=0

The given equation is 4x² = 10 +y²

4x²-y²=10

Divide the whole equation by 10

4x²/10 - y²/10=1

2x²/5- y²/10=1

x²/(1/2)- y²/10=1

The given equation is in the form of hyperbola.

Hence, hyperbola is the conic section described by the equation 4x² = 10 +y²

Answer:

186.5 + 2x

Step-by-step explanation:

First, radify 25. Luckily it's a perfect square so it will be 5.

Second, divide within the parentheses. You're expression should look like this.

(93-5+x+42/8)2

Divide 42/8. The decimal form would be 5.25, while the fraction should be 5 1/4.

Third, solve within the parentheses from left to right. Right now you're expression should look like this:

(93-5+x+5.25)2

Add all like terms

93-5+5.25=93.25

Fourth, multiply. Right now the expression should look like this:

(93.25 + x) 2

186.5 + 2x

Answer:

f(x)⁻¹ = -3x + 15

Step-by-step explanation:

y = -1/3x + 5

x = -1/3y + 5

x - 5 = -1/3y

(x - 5)(-3) = y

-3x + 15 = y

Answer:

They will have the same amount of sugar in their canisters in 15 days

Step-by-step explanation:

Here in this question, we are concerned with knowing the number of days in which the amount of sugar in both canisters will be the same.

Since we do not know the number of days it will take, we have to represent it using a variable.

Let the number of days be x days

Now, we are told Li uses 8.4 g per day.

So in x days, the amount user will be 8.4 * x = 8.4x g

Thus, the amount of sugar remaining in her canister after x days will be 128 - 8.4x

For Sue, she uses 12.6 grams each day. So in x days, the amount of sugar used will be 12.6 * x = 12.6x g

So the amount of sugar left in her canister will be 191-12.6x

Since on the xth day , the amount of sugar remaining is same, we can equate the amount of sugar remaining in both canisters. That would be;

128-8.4x =191-12.6x

Collect like terms;

12.6x-8.4x = 191-128

4.2x = 63

x = 63/4.2

x = 15 days

Step-by-step explanation:

Hey, there!!

To solve this type of equation it is very easy from elimination method,

Here, the given equation are,

-9x+10y = -18..........(i)

3x-y = 6....................(ii)

Let's take LCM to solve for x.

To solve for "x" we must cancel "y".

LCM= 10 { lcm of 1 and 10 is 1}

So, let's multiply equation (ii) by 10 and add them.

Then,

-9x + 10y = -18

30x - 10y = 60

21x = 42 { as +10y and -10y gets cancelled}

[tex]x = \frac{42}{21} [/tex]

Therefore, x= 2.

Substituting the value of x in equation (i)

-9x + 10y = -18

-9 × 2 +10y = -18

-18 + 10y = -18

or, 10y = -18 +18

Therefore, y= 0.

So, the value of x is 2 and y is 0.
