Step-by-step explanation:

Just got a calculator out and started with an estimated guess and changed it till I got it correct.

Answer:

B

Step-by-step explanation:

Slope-intercept form:

y= mx +c, where m is the slope and c is the y-intercept.

Given that the slope is -4/5,

[tex]y = - \frac{4}{5} x + c[/tex]

To find the y-intercept, substitute a pair of coordinates.

When x= -5, y= -4,

[tex] - 4 = - \frac{4}{5} ( - 5) + c \\ - 4 = 4 + c \\ c = - 4 - 4 \\ c = - 8[/tex]

Thus, the equation of the line is

[tex]y = - \frac{4}{5} x - 8[/tex]

Answer:

there are a total of 20 boys and 30 girls in the choir of 50 students

Step-by-step explanation:

Scale the ratio 2:3. so that the numbers on either side sum to 50 . 2+3=5 , and 50÷5=10 , so we scale our ratio by a factor of 10 . So there are a total of 20 boys and 30 girls in the choir of 50 students

Answer:

5,376in^3

Step-by-step explanation:

find the volume of the smaller box first

10×4×12 = 480in^3

find volume of bigger box

17×12×24 = 4,896in^3

add both volumes 4,896 +480 = 5,376in^3

Answer:

v = 5,376

Step-by-step explanation:

So the first thing we have to do is figure out the volume for the first part of the cube figure.

To do this we just multiply H x W x L =

In this case v = 4,896

Now we do the same thing with the other rectangular prism:

10 x 4 x 12 = 480

Now that we have the 2 volumes we add them together:

4,896 + 480 = 5,376

Hence the total volume = 5,376

Answer  

1/5

Step-by-step explanation:

The slope of a perpendicular line is the negative reciprocal. Since y=-5x(m=-5), the slope is -(-1/5) which is 1/5

The slope of a line perpendicular to the line x - y = 6x is 1/5.

Here,

The equation of line whose equation is,

⇒x - y = 6x

We have to find the slope of a line perpendicular to the line x - y = 6x.

What is Equation of line?

The general equation of a straight line is,

y = mx + c

Where, m is the slope of the line.

Now,

The equation of line whose equation is,

⇒x - y = 6x

⇒ y = -5 x

Hence, the slope is -5.

The slope of a perpendicular line is the negative reciprocal.

So, The slope of a line perpendicular to the line x - y = 6x is,

⇒ [tex]-(\frac{1}{-5} )[/tex]

⇒ [tex]\frac{1}{5}[/tex]

The slope of a line perpendicular to the line x - y = 6x is 1/5.

Answer:

[tex]90[/tex]

Step-by-step explanation:

Let the unknown number be x

[tex]x \times \frac{70}{100} = 63 \\ x = \frac{63 \times 100}{70} \\ x = 90[/tex]

Hope this helps

Can I have the brainliest please?

~Hi1315~

Answer:

90

Step-by-step explanation:

If 70% of a number is 63, we can call that number x and make the following equation:

0.7x = 63

Now we just need to solve for x:

x = 63/0.7

x = 90

So the original number is 90.

How do we know we’re right? If you do 70% of 90 (aka 0.7*90), you’ll get 63, so we know it’s correct.

Answer:

[tex]y^2+x^2=9[/tex]

Step-by-step explanation:

Let's take a general point P(x,y). If there is a right angle at P then the slopes of the lines passing through AP and BP must be perpendicular.

Two lines of slopes m1 and m2 are perpendicular if:

m1*m2=-1

The slope of the line passing through P(x,y) and A(3,0) is:

[tex]\displaystyle m_1=\frac{y-0}{x-3}=\frac{y}{x-3}[/tex]

The slope of the line passing through P(x,y) and B(-3,0) is:

[tex]\displaystyle m_2=\frac{y-0}{x+3}=\frac{y}{x+3}[/tex]

Substituting in the equation:

[tex]\displaystyle \frac{y}{x-3}\cdot\frac{y}{x+3}=-1[/tex]

Operating:

[tex]\displaystyle \frac{y^2}{(x-3)(x+3)}=-1[/tex]

[tex]y^2=-(x-3)(x+3)[/tex]

[tex]y^2=-(x^2-9)[/tex]

[tex]y^2=-x^2+9[/tex]

The equation that represents the inequality in the graph is y < 2x + 2.

The solution of the system is (-1, -2).

At least two linear inequalities in the same variables make up a system of linear inequality in two variables. The graph of a linear inequality is the graph of all solutions to the system, and the solution of a linear inequality is the ordered pair that resolves all inequalities in the system.

To find the system of inequalities, first, we find the system of equations.

So, the first dotted line is passing through two points (-1, 0) and (0, 2),

then the equation of the line,

y - 0 = (2 - 0)/(0 + 1) (x + 1)

y = 2x + 2

From the diagram, the equation that represents the inequality in the graph is y < 2x + 2   ....(1)

Similarly, the equation of the second line is y ≤ 2x ...(2)

Now, the solution of the system is (-1, -2).

Therefore, the solution of the system is (-1, -2).
