What is the equation of the line that passes through the point ( 2 , − 3 ) (2,−3) and has a slope of 2

Answers

Answer 1

Answer: y = 2x -7

Step-by-step explanation:

The equation of a line is in the form y = mx + b

We know m = 2

So, y = 2x + b

we need to find b, and we can use either point given to find it:

lets use (2, -3):

-3 = 2(2) + b

-7 = b

now we know, the line's equation is y = 2x -7

Step-by-step explanation:

your teacher wrote most of the solution in this picture.

all we need to do is simplify and transform the equation

28/4 = 21/N

7 = 21/N

7N = 21

N = 21/7 = 3

formally, the ratio of corresponding (side) lengths is the same for all corresponding sides or other lines (like heights) in similar shapes.

so, the rate 28/4 = 7/1 = 7 asked also to 21 and N.

28/7 = 4

and

21/7 = N = 3

Answer:

[tex]\huge\boxed{\boxed{N=3}}[/tex]

Step-by-step explanation:

Hello.

We have the proportion

[tex]\displaystyle\frac{28}{4} =\frac{21}{N}[/tex]

In order to solve a proportion, we should cross-multiply:

28×N=4×21

28N=84

Divide both sides by 28.

N=3

What was the percent increase in the number of phone calls from the second month to the third month? Remember to show your thinking! Use proportions when you can.

Answers

Answer:

20%

Step-by-step explanation:

First month = 4264 phone calls

Second month = 25% more phone calls than the first month

⇒ second month = 4264 × 1.25 = 5330

Third month = 6396 phone calls

[tex]\mathsf{percentage \ change=\dfrac{|final \ value - initial \ value|}{initial \ value}\times 100\%}[/tex]

[tex]\implies \mathsf{percentage \ change=\dfrac{6396 - 5330}{5330}\times 100\%}[/tex]

Question: write an equation for each parabola with vertex at the origin

Problem: through (3,2); symmetric with respect to the x axis

Answers

Step-by-step explanation:

Since the axis of symmetry is the x axis, we have a sideways parabola,

[tex] {y}^{2} = x[/tex]

Since the vertex is at the orgin, our answer will be

[tex]a(y - k) {}^{2} + h = 0[/tex]

[tex]a {y}^{2} = x[/tex]

It passes through (3,2).

[tex]a(2) {}^{2} = 3[/tex]

[tex]a(4) = 3[/tex]

[tex]a = \frac{3}{4} [/tex]

So our function is

[tex] \frac{3}{4} {y}^{2} = x[/tex]

Answer:

[tex]x=\dfrac34y^2[/tex]

Step-by-step explanation:

A graph with x-axis symmetry means that for every (x, y) point there is also a (x, -y) point on the graph, i.e. the x-axis acts like a mirror.  Therefore, it is a sideways parabola.

The general form of this type of equation is [tex]x=ay^2+by+c[/tex]

Since we know that the curve has a vertex of (0, 0) then [tex]c=0[/tex]

Therefore, [tex]x=ay^2+by[/tex]

Given that (3, 2) is on the curve, then (3, -2) is also on the curve.

Substituting the given point (3, 2):

[tex]3=a(2)^2+b(2)[/tex]

[tex]3=4a+2b[/tex]

Substituting the given point (3, -2)

[tex]3=a(-2)^2+b(-2)[/tex]

[tex]3=4a-2b[/tex]

Adding the equations together to eliminate [tex]b[/tex]:

[tex]\implies 6=8a[/tex]

[tex]\implies 3=4a[/tex]

[tex]\implies a=\dfrac34[/tex]

Therefore,

[tex]x=\dfrac34y^2+by[/tex]

Again, substituting point (3, 2) means that b = 0

Therefore, the final equation is:

[tex]x=\dfrac34y^2[/tex]

Which equation determines d, the cost in dollars to clean r rooms?

To check :--

=> d = 29r + 10

according to the table lets insert 3 to check if it's correct

=> d = 29r + 10

=> d = 29(3) + 10

=> d = 87 + 10

=> d = 97

so therefore it gave us the correct answer according to the table the cost in dollar where 97 and since it gives us 97 it's correct

ur question is incompleteness

The value of the investment at the end of 3 years would be [tex]\£7,524.6[/tex].

Used the formula of the total amount that is,

[tex]A = P (1 + r)^n[/tex]

Where A = Total amount.

P = Principal amount

r = Interest rate (in decimal form)

n = Number of years

Given that,

Chloe invests £6500 for 3 years at 5% per annum compound interest.

Here the given values are,

P = £6500

n = 3 years

r = 5% = 0.05

Substitute all the values in the above formula,

The value of the investment at the end of 3 years is,

[tex]A = P (1 + r)^n[/tex]

[tex]A = \£6500 (1 + 0.05)^3[/tex]

[tex]A = \£6500 \times (1.05)^3[/tex]

[tex]A = \£6500 \times 1.05 \times 1.05 \times 1.05[/tex]

Therefore, the investment at the end of 3 years is,
