Answer:

350000

Step-by-step explanation:

500 × 700 = 350000

Answer:

500 × 700 = 350000

Answer:

x=0, y = 3/2

Step-by-step explanation:

Ok, for substitution, you need to solve for y in terms of x, I'll do this for the first eqyation

8y=-7x+12

y=-7/8x+3/2, now plug in y in the second equation

-4x+2(-7/8x+3/2)=3, solve for x now

-4x-7/4x+3=3,

-4x-7/4x=0, x=0 now plug in 0 for either equation to solve for y

-4(0)+2y=3

2y=3, y=3/2

Answer:

Slope: 7/4 Equation: y = 7/4x

Step-by-step explanation:

To find the slope check how much the line goes up when it goes to the right by 1. You can see in the picture that every time it goes to the right 8, it goes up by 14, so the slope is 14/8 = 7/4.

Since it goes through the point (0, 0) and the slope is 7/4,  you know the equation would just be y = 7/4x

Answer: slope= 7/4

               equation= y=7/4x

Step-by-step explanation: rise over run for the slope and y=mx+b for the equation

Answer:

z=2256

did you mean

2z=4512?

i hope this was the question and that the answer is correct!^^

Answer:

34cm

Step-by-step explanation:

To find the missing sides you have to see how much the bottom is, then the other sides so in the case the bottom is 10cm and top is 3cm on each side. and you want to find the middle. so you would do 10 - 3 - 3 = 4

I think it is a and b if am not wrong good luck

Answer:

Step-by-step explanation:

f(x) = ln x

g(x) = - f(x - 4)

g(x) = - ln (x - 4)

g(5) = - ln (5 - 4) = - ln 1 = 0

Answer:

n=4

Step-by-step explanation:

Combine multiplied terms into a single fraction

3 4 = 3 3 4 = 3 2

Multiply all terms by the same value to eliminate fraction denominators

3 4 = 3 4 ⋅ 3 4 = 4 ⋅ 3 3

Simplify

Cancel multiplied terms that are in the denominator

Multiply the numbers

3 = 1 2 4

Divide both sides of the equation by the same term

3 = 1 2 3n 3 = 1 2 3 5

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

= 4

Solution

= 4

Answer:

(x+4)(x+3)

Step-by-step explanation:

x^2+4x+3x+12

take x out of each

x(x+4)+3x+12

take 3 out

x(x+4)+3(x+4)

(x+3)(x+4)

Answer:

128degrees

Step-by-step explanation:

Note that the given triangle ABC is an isosceles triangle with base angles equal, hence;

m∠BAC = m∠BCA

7x+1 = 5x+9

7x - 5x = 9-1

2x = 8

x = 8/2

x = 4

m∠BAC = 5x+6

m∠BAC = 5(4)+6

m∠BAC = 26 degrees

The vertex angle = 180 - (26+26)

The vertex angle = 180 - 52

The vertex angle = 128degrees

Answer: x=12

brainliest plzzz

I don't expect you to pay me or give me brainliest. Just want to help.

Step-by-step explanation:

I'll start with the answers to each one, then explain exponents.

1) 5^4 = 625

2) x^3 = 0

3) 2^-1 = 0.5

4) 2^0 = 1

An exponent is a quantity representing the power to which a given number or expression is to be raised. (Don't use this exact definition in your answer.)

I'll use 5^4 as an example.

5^4 has a positive exponent, which means 5 is multiplied by itself 4 times.

5 * 5 * 5 * 5 = 625.

The number 5 here is considered the base.

In x^3, x is the base.

In 2^-1, 2 is the base, and so on.

If the exponent is 0, like 2^0, the answer is 1, regardless of the base.

5^0 = 1, 10^0 = 1, 3^0 = 1, and so on.

If the exponent is negative, like 2^-1, you will use this process;

2^-1 = 1/(2^-1) = 1/2 = 0.5

Here's a better example.

2^(-4) = 1/(2^4) = 1/(2*2*2*2) = 1/16 (or) 0.0625

Good luck mate. :)

Answer:

To prove that N is a proper subset of M, show that every element of N is an element of M but there exists some elements of M which are not in N.

M= {4, 8, 12, 16, 20, 24...}

N= {12, 24, 36, 48, 60...}

Similar to example 6, 12 is a multiple of 4.

If x∈N,

then x= 12m for some positive integer m.

∴ x= 4(3m)

Hence, x is a multiple of 4.

i.e. x∈N.

Thus, every element of N is an element of M, but there exists some elements of M which are not elements of N. For example, 4, 8 and 16 are elements of M but are not elements of N. Thus, N is a proper subset of M. (shown)

Explanation:

∈ is the symbol of 'element of'. Thus, x∈N means that x is an element of N.

☆ Think of subsets like subtopics:

If differentiation is a subtopic of calculus, differentiation is a part of calculus but calculus is not only about differentiation since it includes integration too. Thus, there are numbers, which we call elements, in M that are not in N but all elements in N are in M.

Answer: Poggers

Explanation: Yeah

Answer:

w = 1.5m + 8

Step-by-step explanation:

Basically what the question says is that the weight of a baby is equal to 8  plus the weight he gained. So then we can make the following equation...  

w = (weight he gained) + 8

(the weight gained is equal to the age in months times 1.5 pounds, so now the formula becomes.....)

w = 1.5m + 8

Answer:

The result in standard form is:

[tex]\left(-5t+4t^2-t\right)-\left(8t^2+t\right)=-4t^2-7t[/tex]

Step-by-step explanation:

Given the polynomials

subtracting 8t² + t from -5t+ 4t² – t.

[tex]\left(-5t+\:4t^2\:-\:t\right)\:-\:\left(8t^2\:+\:t\right)[/tex]

Remove parenthese: (-a) = -a

i.e. - (8t² + t) = 8t² - t

so the expression becomes

[tex]=-5t+4t^2-t-8t^2-t[/tex]        

grouping the like terms

[tex]=4t^2-8t^2-5t-t-t[/tex]

Add similar elements: 4t² - 8t² = -4t²

[tex]=-4t^2-5t-t-t[/tex]

Add similar elements: -5t - t - t = -7t

[tex]=-4t^2-7t[/tex]

Therefore, the result in standard form is:

[tex]\left(-5t+4t^2-t\right)-\left(8t^2+t\right)=-4t^2-7t[/tex]

Answer:

$123.48 per week

Step-by-step explanation:

$ = (13.72)(9)

Multiply:

$123.48

The earnings of Adam based on the given rate will be $123.48.

The rate of change is the change of a quantity over 1 unit of another quantity.

Most of the time the rate of change is the change with respect to time.

For example the speed 3meter/second.

As per the given,

Adam earns $13.72 each hour.

For 9 hours the earnings will be,

⇒ $13.72/hour × 9 hour

⇒ $123.48

Hence "The earnings of Adam based on the given rate will be $123.48".
