Joe had a balance of $34 on his credit card. He bought a sandwich and charged $40 on his credit card. 1a.) Write an equation that represents this scenario.

Answer:

D. $5.19

Step-by-step explanation:

Answer:

k = 146

m= 106

Kirchoff has $146

Maxi has $106

Step-by-step explanation:

For the purpose of the equations, I’ll call Kirchoff and Maxi a and b respectively.

a - 20 = b + 20 (equation 1)

2(b - 22) = a + 22 (equation 2)

We can juggle those around for

a = b +40 (equation 1r (re-arranged)) and

2b - 44 = a + 22 so 2b - 66 = a (equation 2r (rearranged))

The equations are now:

a = b + 40 (new equation 1) and

a = 2b - 66 (new equation 2)

Substitute from new equation 1 to new equation 2:

b + 40 = 2b - 66 so 40 = b - 66 making b = 106.

Plug b = 106 into new equations 1 and 2 for:

a = 106 + 40 (new equation 1) and

a = 212 - 66 (new equation 2)

This gives a = 146 and b = 106

TEST: There’s a gap of $40, so giving $20 from a to b makes them equal.

SECOND TEST: Subtracting $22 from b makes it $84 and giving that sum to a makes it $168, twice as much. The tests work.

Kirchoff has $146 and Maxi has $106.

so 3x2 equals 6 and 0 x 1 equals 0 so 0x6 equals 0 so its zero

Answer:

0

Answer:

12

Step-by-step explanation:

the answer is 12

Answer:    12sq. units

Step-by-step explanation: Because if you take it and say it has 2 for the side and down below it has 6 you times that and you get 12.

Can you mark me brainlest???!!! Please!!!!!

Answer:

  y = -3x - 23

Step-by-step explanation:

When a transversal of the two lines is constructed, the alternate interior angles formed by the transversal are congruent. This means line m and n are parallel to each other so their slope will be the same.

Given:

  line m:   y = -3x + 8                 <======= slope is -3

line n going through point (-4, -11) with same slope as line m:

  y = mx + b

  (-11) = -3(-4) + b

  -11 = 12 + b

  b = -23                                    <===== y-intercept of line n

Use the above slope and y-intercept to form equation of line n:

  y = mx + b

  y = -3x - 23

Answer:

a. Yes

b. minutes 3 to 6

c. yes, as long as they do not have the same x-value.

I got the answer from the question after getting it wrong

Answer:

Result after multiplication of polynomial is: [tex]6x^3+13x^2-5x[/tex]

Degree of polynomial = 3

Step-by-step explanation:

The given polynomials are:

[tex]x(3x-1)(2x+5)[/tex]

In order to multiply the given polynomials we have to work step by step. First of all the polynomials in the bracket will be multiplied and then their result will be multiplied with x.

So, multiplying the polynomials in round brackets first

[tex]=x(3x-1)(2x+5)\\= x\{3x(2x+5)-1(2x+5)\}\\=x\{6x^2+15x-2x-5\}\\=x(6x^2+13x-5)[/tex]

Now multiplying with x

[tex]= 6x^3+13x^2-5x[/tex]

Degree of a polynomial is the highest exponent of variable in the polynomial.

In the acquired result, the highest exponent of x is 3 so the degree is 3.

Hence,

Result after multiplication of polynomial is: [tex]6x^3+13x^2-5x[/tex]

Degree of polynomial = 3

Answer:

So the equation of the line that passes through (3, 1) and (0, 10) is y=-3x+10

Step-by-step explanation:

(3, 1) and (0, 10)

m=y²-y¹/x²-x¹

m=10-1/0-3

m=9/-3

m=-3

y=mx+b

y-y=m(x-x1)

y-1=-3(x-3)

y-1=-3x+9

+1 +1

y=-3x+10

Answer:

p = 1

Step-by-step explanation:

Multiply both sides of the equation by 5

2 + 5p = 3 + 3p

reraange for p

p = 1

Step-by-step explanation:

Theoretical probability is fixed/remains the same because it is based on theory which is calculated, while the experimental probability is based on data that is gained from actually doing it. According to the law of large numbers, the average experimental probability always approaches the theoretical probability.

Answer:

13

Step-by-step explanation:

∠Q ≅ ∠ P ⇒ RP = RQ = 13

Answer:

for an expression to be a polynomial term, it must contain no square roots of variables, no fractional or negative powers on the variables, and no variables in the denominators of any fractions. Here are some examples: This is NOT a polynomial termbecause the variable has a negative exponent.

Answer:

Points B and C are opposite

Step-by-step explanation:

0 on the number line marks the center of the number line. To the right on the number line are positive integers and to the left from zero are negative integers.

Points B and C are opposite because they are each half way between 0 and 1 on the right and 0 and -1 on the left

Answer:

b and c are opposites
