Answer:

B. 3x + y = 4

Step-by-step explanation:

y = -3x + 4

Check:

3x + y = 4

-3x        -3x

y = -3x + 4

Answer:

It is B

Step-by-step explanation:

This is because if you use the point (1,1) for example then both x and y are 1.

1 X 3 = 3 and 3 + 1 = 4.

Answer:

If you take a look at, 1.5 kilometers you can see that Mercury from the Sun is 5.8, it is also asking how many more kilometers is the distance of earth, so if you look at 5.1 and D which is 5.7 you would add those last digits together and get 5.8 so therefore your answer could possibly be D) 5.7 ⋅ 109 kilometers

Answer:

He would pay $287 if he races 39 times

Thus, the membership fee is $14.

Step-by-step explanation:

Linear Modeling

The situation described in the problem can be modeled as the equation of a line which has the form:

[tex]y=ax+b[/tex]

Where y is the cost of the course, x is the number of races, a is the cost per race, and b is the membership fee.

We know the course charges $7 per race, so a=7. Since your friend has raced x=28 times and paid y=210, we can find the value of b:

[tex]210=7(28)+b[/tex]

Operating:

[tex]210=196+b[/tex]

b=14

Thus, the membership fee is $14.

The linear model is now:

[tex]y=7x+14[/tex]

If he races x=39 times, your friend would pay:

[tex]y=7(39)+14=287[/tex]

y=287

He would pay $287 if he races 39 times

PEMDAS - Please Excuse My Dear Aunt Sally - Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

Answer: 88 cones.

Step-by-step explanation:

We know that:

price of a cone = $1.10

price of a sundae = $2.35

A total of 172 cones and sundaes were sold for $294.20

Then we can define two variables:

C = number of cones sold

S = number of sundaes sold.

C + S = 172 (the total number of sundaes and cones sold is 172)

C*$1.10 + S*$2.35 = $294.20  (that is how much the won).

Then we have the system of equations:

C + S = 172

C*$1.10 + S*$2.35 = $294.20

And we want to find how many cones were sold.

To solve this, we first need to isolate the other variable, S, in one of the equations, i will isolate S in the first equation:

S = 172 - C

Now, let's replace this in the second equation:

C*$1.10 + (172 - C)*$2.35 = $294.20

Now we can solve this for C, and find the number of cones that were sold.

C*$1.10 + $404.20 - C*$2.35 = $294.20

C*($1.10 - $2.35) = $294.20 - $404.20

-C*1.25 = -110

C = 110/1.25 = 88

88 cones were sold.

5>0-3

Step By Step- 5 is greater than 0-3 because 0-3 would equal a negative number, and all positive numbers are greater than negative numbers

Answer:

5>0-3

Step-by-step explanation:

The inequality is represented by the given graph is y ≤ -x/3+1.

The correct option is B.

An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.

We have,

A graph of an inequality, passing by (0, 1) and (3, 0).

A and D are eliminated since the line is solid.

C is disregarded because the line is shaded below as well.

Then, the inequality will be y ≤ -x/3+1

Hence, the inequality is represented by the given graph is y ≤ -x/3+1.

Answer: the best coupon for this case is WELCOME25, and the cost will be $30.

Step-by-step explanation:

We know that:

Price for pans = $22

Price for pots = $9.

If the customer buys two pots and one pan, he would pay::

C = 1*$22 + 2*$9 = $40.

If the customer uses the coupon 2POTSFOR1

Then he will pay only one of the pots, and the total cost will be:

C = 1*$22 + 1*9 = $31.

If the customer uses the WELCOME25 coupon, then the cost will be a 75% of the original cost.

if 100% = $40

then:

 75% = C

Where

We can take the quotient of these equations and get:

 (C/$40) = (75%/100%)

C = (75%/100%)*$40

C = 0.75*$40 = $30

Then the best coupon for this case is WELCOME25, and the cost will be $30.

Answer:

y = 2x - 4

General Formulas and Concepts:

Alg I

Slope-Intercept Form: y = mx + b

Parallel Lines have the same slope but different y-intercepts.

Step-by-step explanation:

Step 1: Define

y = 2x + 1

Step 2: Break function

Slope m = 2

y-intercept = 1

Step 3: Set up parallel line

y = 2x + b

8 = 2(6) + b

8 = 12 + b

b = -4

y = 2x - 4

Answer:

y = 2x - 4

Step-by-step explanation:

y - y1 = m(x - x1)

y - 8 = 2(x - 6)

y - 8 = 2x - 12

 + 12       + 12

y + 4 = 2x

  - 4     - 4

y = 2x - 4  ------- formula for slope-intercept form: y = mx + b
