Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

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

[tex]m[/tex] - slope

[tex]b[/tex] - y-intercept

Given

[tex]m=-\dfrac{8}{7}[/tex]

and point [tex](7;\ -5)[/tex]

Substitute the value of the slope and the coordinates of the point ot the equation of a line:

[tex]-5=-\dfrac{8}{7\!\!\!\!\diagup}\cdot7\!\!\!\!\diagup+b[/tex]     cancel 7

[tex]-5=-8+b[/tex]           add 8 to both sides

[tex]-5+8=-8+8+b[/tex]

[tex]3=b\to b=3[/tex]

Therefore we have the equation of the line:

[tex]y=-\dfrac{8}{7}x+3[/tex]

Substitute (x, 3) to the equation:

[tex]3=-\dfrac{8}{7}x+3[/tex]          subtract 3 from both sides

[tex]3-3=-\dfrac{8}{7}x+3-3[/tex]

[tex]0=-\dfrac{8}{7}x[/tex]           divide both sides by (-8/7)

[tex]0=x\to x=0[/tex]

Answer:

1.99 * 10^4

Step-by-step explanation:

Here, we want to write the addition in standard form

= (1 * 10^4) + (9 * 10^3) + (9 * 10^2)

= 10,000 + 9000 + 900

= 19,900

so the number in standard form is;

1.99 * 10^4

Step-by-step explanation:

Answer:

y= 5x-20

Step-by-step explanation:

I didn't understand if I had to find the perpendicular line or parallel haha.

You’re welcome :)

Answer:

y = 5x -20

Step-by-step explanation:

for the line to be perpendicular it must have the inverse slope

therefore m = 5

no substitute the point (2, -10) in for (x, y) respectively to find the y intercept

-10 = 5(2) + b

-10 = 10 + b

b = -20

the equation will be y = 5x -20

Answer:

48 students total in the school play

Ratio of boys to girls is 5:7  

How many more girls are there than boys in the play?

Let's let "5x" represent the number of boys in the school play and "7x" represent the number of girls in the school play.

5x = boys

7x = girls

 If we know that the total number of students in the play equals 48, then that must me that both the number of boys and girls combined must equal 48:

5x + 7x = 48

12x = 48

x = 4

Now, take your x-value and plug it into both the boys' and girls' values to figure out how many boys and girls there are in the play:

5x = 5 (4) = 20 boys  

7x = 7 (4) = 28 girls

To find out how many more girls there are than boys in the play, just subtract the number of girls minus the number of boys:

# girls - # boys = 28 - 20 = 8

This means that there are 8 more girls than boys in the school play.

Step-by-step explanation:

Answer:

1. Y = 6

2. Y = 8

3. Y = 1

4. Y = 3

Step-by-step explanation:

1. Y = -(-1) + 5 = 1 + 5 = 6

2. Y = -(-3) + 5 = 3 + 5 = 8

3. Y = -4 + 5 = 1

4. Y = -2 + 5 = 3

Answer:  Choice (3)

2 + log(a) + 2*log(b)

======================================================

Work Shown:

The log rules we'll use are

So,

c = log(100ab^2)

c = log(100) + log(a) + log(b^2) ......... use log rule 1

c = log(10^2) + log(a) + log(b^2)

c = 2*log(10) + log(a) + 2*log(b) ......... use log rule 2

c = 2*1 + log(a) + 2*log(b) .................... use log rule 3

c = 2 + log(a) + 2*log(b)

Note: The use of rule 3 assumes that all logs shown are in base 10, which is the default assumed base. Rule 3 doesn't work for any general base. The more generalized rule is [tex]\log_b(b) = 1[/tex]. If b = 10, then we get rule 3 above.

Answer:

5. a^3 + b^3 = (a+b)^3 - 3ab(a+b)

Step-by-step explanation:

(a+b)^3

= (a+b) (a+b) (a+b)

={(a+b) (a+b)} (a+b)

={a(a+b) + b(a+b)} (a+b)

=(a^2 + ab + ab + b^2) (a+b)

=(a^2 + b^2 + 2ab) (a+b)

=a^2(a+b) + b^2(a+b) + 2ab(a+b)

=a^3 + a^2b + ab^2 + b^3 + 2a^2b + 2ab^2

=a^3 + b^3 + 3a^2b + 3ab^2

=a^3 + b^3 + 3ab(a+b)

(a+b)^3 = a^3 + b^3 + 3ab(a+b)

(a+b)^3 - 3ab(a+b) = a^3 + b^3

a^3 + b^3 = (a+b)^3 - 3ab(a+b)

Hope this helped!

The rest are wrong.

Hi there! :)

We are given the slope of the line and its y-intercept.

So, we write the equation in slope-intercept form (y=mx+b)

m is the slope of the line, and b is the y-intercept.

y=mx+b

y=-4x-3

Hence, that's the equation (Option A)
