Answer:

y=6x-5

Step-by-step explanation:

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

Finding the slope:

Use this...

[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

Plug in what you know...

[tex]y_{2} =-5\\y_{1}=7\\x_{2} =0\\x_{1}=2[/tex]

Now solve...

[tex]\frac{-5-7}{0-2}=\frac{-12}{-2} =6[/tex]

So the slope is 6.

Finding the y-intercept:

Use this...

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

Plug in what you know...

(2,7)    (I'll be using this pair but you can choose the other one)

[tex]y = 7\\x = 2\\m = 6[/tex]

Now solve...

[tex]7=6(2)+b\\7=12+b\\b=-5[/tex]

Writing the equation:

Use this...

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

Plug in what you know...

[tex]m=6\\b=-5[/tex]

Now write it out...

[tex]y=6x-5[/tex]

That's it

Answer:

2640 miles

Step-by-step explanation:

If the train goes 110 miles per hour, and there are 24 hours in a day, and you multiply them together, you get 2640, hope this helps!

Answer:

The train will go 2,640 miles in one day

Step-by-step explanation:

110*24 = 2,640

PEMDAS:

perenthesis, exponents, multiplication + division, addition and subtraction.

so you add first, to get 12+5=17.

then you multiply, to get 5*17 =85

Answer:

85

Step-by-step explanation:

PEMDAS:

First you do parenthesis so add the 12 and 5 together to get 17.

Now you are left with 5(17).

from there multiply to get your answer.

85

If it's just the 7 that's repeating, let

x = 0.1777...

Then

10x = 1.777...

100x = 17.777...

100x - 10x = 17.777... - 1.777...

90x = 16

x = 16/90 = 8/45

If both 1 and 7 are repeating, let

x = 0.171717...

Then

100x = 17.171717...

100x - x = 17.171717... - 0.171717...

99x = 17

x = 17/99

Answer:

FH=7

Step-by-step explanation:

If the whole thing FG is 22 and HG is 15 you subtract 22-15 and get 7

Step-by-step explanation:

[tex]\huge\bold\purple{ 7 }[/tex]

Solve

5x + 2x -6 = -2(x - 1)

7x - 6 = -2(x-1)

Distribute

7x - 6 = -2(x - 1)

7x - 6 = -2x + 2

Add 6 to each side

7x - 6 + 6 = -2x + 2 + 6

Simplify

7x = -2x + 8

x = 8/9

So your answer is B. I believe

5x + 2(x - 3) = -2(x - 1)

its 8/9

Answer:

[tex]-0.04b^{19}[/tex]

Step-by-step explanation:

We have the expression [tex](-0.2b^6)^3\times 5b[/tex] and we want to rewrite/simplify this to a monomial (only one term).

First, let's expand. We can use the power of a product exponent property, where [tex](ab)^x=a^xb^x[/tex]

We have:

[tex](-0.2b^6)^3\times 5b[/tex]

Using the above property, this will be:

[tex]=(-0.2)^3(b^6)^3\times5b[/tex]

(-0.2) cubed is -0.008. So, this becomes:

[tex]=-0.008(b^6)^3\times 5b[/tex]

We can now use the power of a power property, where [tex](x^a)^b=x^{ab}[/tex].

Therefore, this will give us:

[tex]=-0.008b^{6\times 3}\times 5b[/tex]

Evaluate:

[tex]=-0.008b^{18}\times 5b[/tex]

Notice that 5b is the same as 5 times b to the first power. So:

[tex]=-0.008\times b^{18}\times5\times b^1[/tex]

We can rearrange this to get:

[tex]=-0.008\times 5\times b^{18}\times b^1[/tex]

When we multiply exponents with the same base, we will simply add the exponents. -0.008 times 5 is -0.04. Therefore, this yields:

[tex]=-0.04b^{18+1}\\=-0.04b^{19}[/tex]

Therefore, our final answer is [tex]-0.04b^{19}[/tex].

And this is indeed a monomial since this only has one term.

Depends on what kind of expression you are talking about, A mathematical expression, or a normal expression.

Answer:

y = 15

Step-by-step explanation:

You can use the addition property of equality.

1) time 3 to +3 and 5

3 x /3 = 0

3 x 5 = 15

2) Now, we are left with y = 15

Therefore, y = 15

Answer:

Maximum: 74

Minimum: 70

Step-by-step explanation:

l s - 72 l = 2

s - 72 = 2

s = 74

s - 72 = -2

s = 70

The maximum score will be 74 and the minimum score will be 70.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Leona was in a golf tournament last week. All of her rounds of gold were within 2 strokes of par and par was 72.

The value of the maximum and minimum scores will be calculated as below:-

Maximum score:-

l s - 72 l = 2

s - 72 = 2

s = 74

Minimum score:-

s - 72 = -2

s = 70

Therefore, the maximum score will be 74 and the minimum score will be 70.

Answer:

5 1/2

Step-by-step explanation:

The calories contained are from grams of carbohydrates and other ingredients

One gram of carbohydrate contains 4 calories

The equation 4c + 5 = 27 represents the relationship between these quantities.

1. 5 from the equation represent calories from other ingredients

2. Neither 8 nor 3 is the solution to the equation

4c + 5 = 27

When 8 is the solution

4(8)+5=27

32+5=27

37=27

When 3 is the solution

4(3)+5=27

12+5=27

17=27

Neither 8 nor 3 is the solution to the equation because 8 gives a higher calories in the granola bite and 3 gives a lower calories in the granola bite.

3. Solution to the equation

4c + 5 = 27

4c= 27-5

4c = 22

Divide both sides by 4

c=22/4

=5 2/4

=5 1/2

The solution to the equation is 5 1/2

Answer:2 pi

Step-by-step explanation: The reason I know this is because I plugged into a graphing calculator and took the unit test.

At value D.2pi  the graph of y=4 cot^-1(2x) intersect the y-axis.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Here, given that,

y=4 cot^-1(2x)

we have to find the value at it  intersect the y-axis.

y-axis means x=0.

So, here the value is D.2pi.

Answer:

y = 23x/7 +48/7

Step-by-step explanation:

perpendicular slopes are always equal to -1

so the new slope is 23/7

slope intercept form is y = mx + b where m is the slope and b is the                 y-intercept

so plug in (-3, -3 ) to get -3 = 23(-3)/7 + b

isolate b

solve

-3 = 23*-3/7 + b

-3 = -69/7 + b

add 69/7 to both sides

69/7 - 3 = b

-3 = -21/7

69/7 - 21/7 = 48/7

b = 48/7

new equation is y = 23/7 + 48/7

Answer:

The second base of the trapezoid b2 is 2.5 inches

Step-by-step explanation:

Here, we want to calculate the second base of the trapezoid.

Mathematically, the area of a trapezoid can be given as;

A = 1/2(a + b) h

where a and b represents the parallel bases and h is the height of the trapezoid

so this, we have from the question

1/2(4.5 + b2) * 6 = 21

3(4.5 + b2) = 21

divide both sides by 3

4.5 + b2 = 7

b2 = 7-4.5

b2 = 2.5 inches

no beacuse of the x and y coordinate which is two points

Step-by-step explanation:

Answer:

x=36

Step-by-step explanation:

the triangle is a right angle triangle divided into 2 at the angle representing 90°. Since the second triangle has two equal sides the angles therefore are also equal, hence

180°-72°=108°

then 108°÷2=54°. ( we divided because the angles are equal.

x=180°-90°-54°

x=36°
