Answer 1

Answer:
9x+2y=-10

Explanation:
First, we would need to organize the information given into slope-intercept form.

Slope-intercept form: y=mx+b

Here’s what the variables mean:
Y=the y coordinate
M=the slope
X=the x coordinate
B=the y-intercept (the point on the line that intercepts the y-axis)

When a linear equation in slope-intercept form is complete, the x and y variables are left just as they are. Knowing this, we just have to plug in the values given for the coordinate and solve for b, the y-intercept.

(-2,4),
y=mx+b
4=m(-2)+b
4=-2(-9/2)+b
4=9+b
Subtract 9 on both sides
4-9=9+b-9
-5=b

Awesome! Now, we know that the equation in slope-intercept form is:

y=-9/2x-5

To organize it into standard form, we need to move some things around.

Standard form: Ax+By=C

(A, B and C don’t have any kind of direct interpretation on a graph.)

y=-9/2x-5
Move the x variable to the other side
9/2x+y=-9/2x-5+9/2
9/2x+y=-5

It may look like we’ve finished here, but A, B and C need to be integers, meaning we cannot have any fractional values in these places.

9/2x+y=-5
Multiply both sides by 2 since it is the denominator
9x+2y=-10

I hope this helps! Please comment if you have any questions.

Write the ratio as a unit rate. Simplify. 216 diving student and 12 instructor

Answers

Answer:

Ratio students to classroom in school A equals 216:12 which simplifies to 18:1. Ratio students to classroom in school B equals 104:4 which simplifies to 26:1.Total students combining school A and B equals 216+104=320 and Total classroom 12+4=16, if both school combined are assumed to be a single school C, than ratio of of students to the classroom in school C equals 320:16 which simplifies to 20:1 which means 20 students in every classroom, now total students in 4 classroom of School C equals 20x4=80, these 4 classroom are separated as School B and other 12 classroom School A, now ratio still 20:1 (same in both schools). initially students in School B were 104 and now are 80, then total students transferred equals 104-80= 24.

Anybody please ? I suck at math !

Answers

Answer:

C. f(x) = x - 7 all over 4

Step-by-step explanation:

NB: Let f(x) = y

Exchange X and Y

Make y the subject

f(x) = 4x + 7

y = 4x + 7

x = 4y + 7

x - 7 = 4y

x - 7 all over 4 = 4 ÷ 4

y = x - 7 all over 4

Four friends made 55 cupcakes and shared them equally.
How many cupcakes did each friend get?

Answers

The answer would be 13.75 so 13 cupcakes each with leftovers

Out of the 55 cupcakes shared equally among four friends each friend will have 13 cupcakes.

What is the unitary method?

A unitary method is a mathematical technique for finding the value of a single unit and then deriving the required units by multiplying with the single unit.

To find how many cupcakes each friend gets we can use the unitary method.

Given four friends made 55 cupcakes, therefore each friend can have (55/4) = 13.75 cupcakes, But the no. of cupcakes should be integers.

∴ Each friend can have 13 cupcakes.

A relation between two variables a and b is a rule that takes some values a from a domain set and returns some value b in the range set.

The table says that, if you give 0, the relation returns 2. If you give 1, you get 6. If you give 4, you get -9. If you give 8, you get 8 back.

The domain is the set of values the relation can take, so here it is the set {0, 1, 4, 8}.

From the given choices, only 0 belongs to the domain.

14 is the GCF of a number M and 210. What are possible values of M?

Answers

Answer:

Hello,

we know that to find the GCF we descompose the numbers and then we multiply the common terms with the lowest exponent. So we first descompose 210:

210 | 2

105 | 3

35 | 5

7 | 7

210= 2x3x5x7

Now one possible solution is 14 because:

14 | 2

7 | 7

As you can see 2 and 7 are common terms, so:

GCF= 2x7

GCF=14 --> It's correct

Then, if we analyze it, we'll realize that we have an infinitive number of solutions. The only requirement is that "M" must have 2 and 7 when we descompose it.

For example:

M= 2²x7x3x11

M=924

924 is another possible solution, it doesn't matter if 2 or 7 repeat, since I said the GCF is the multiplication of the common terms with the LOWEST exponent. That's all.

The table shows the outputs, y, for different inputs, x:
Input (x) 3 4 5 6
Output (y) 3 4 5 6
Part A: Do the data in this table represent a function? Justify your answer. (3 points)
Part B: Compare the data in the table with the relation f(x) - 2x + 16. Which relation has a greater value when x = 6? (2 points)
Part C: Using the relation in Part B, what is the value of x if f(x) - 40? (5 points)
(10 points)

Answers

Answer:

A) is a function

B) f(x) is greater

C) x = 12

Step-by-step explanation:

A) Yes, the relation is a function.

A function has a unique input value for each output value. There are no repeated x-values, so this relation is a function.

B) The table says y=6 for x=6.

f(6) = 2(6)+16 = 28

f(x) has a greater value for x=6.

C) Substituting the given information, we have ...

40 = 2x +16

24 = 2x

12 = x

The value of x is 12 when f(x) is 40.

Sales tax is calculated as a percentage of the sales price. If sales tax is 6%, what is the sales tax on clothing that costs $180? (3 points)

Answers

Answer:

10.80

Step-by-step explanation:

Sales price x sales tax rate = sales tax

180 x .06 (6%) = 10.80

The amount of sales tax for the clothing that costs $180 is $10.8.

Given that,

Cost of a clothing = $180

We have to find the sales tax amount.

Sales tax is calculated as a percentage of the sales price.

Here,

Sales tax percentage = 6%

In order to find the actual sales tax amount, we have to multiply the cost with the percentage of sales tax.

Sales tax amount = 6% of 180

= (6/100) 180

= 0.6 × 18

= 10.8

Hence the sales tax amount is $10.8.
