Hi everyone, God bless you all, I need help on this, Select each correct answer, thx.

Answer:

a) -4

b) 1/4

Step-by-step explanation:

a) -4. This is because parallel lines have the same slope.

b) 1/4. This is because the product of perpendicular slopes will be -1. (This can be seen as -4 * 1/4 = -1)

Step-by-step explanation:

d = number of dimes

n = number of nickels

q = number of quarters

d + n + q = 500

d×$0.10 + n×$0.05 + q×$0.25 = $72.50

n = d

we are focusing now on one variable (let's try d), and we are transforming the other equations to express the other variable by this one variable.

since n = d we have already

d + d + q = 500

2d + q = 500

q = 500 - 2d

with that we go into the main equation

d×0.10 + d×0.05 + (500 - 2d)×0.25 = 72.50

d×0.15 + (500 - 2d)×0.25 = 72.50

d×0.15 + 500×0.25 - 2d×0.25 = 72.50

d×0.15 + 125 - d×0.50 = 72.50

-d×0.35 = -52.50

d = 52.50/0.35 = 150

n = d = 150

q = 500 - 2d = 500 - 2×150 = 500 - 300 = 200

so, he has 200 quarters.

Step-by-step explanation:

Just search up square root of 12 and then subtract 3 from it.

Using the probability concept, it is found that there is a 0.6087 = 60.87% probability of a puppy having no spots.

A probability is the number of desired outcomes divided by the number of total outcomes, that is:

[tex]p = \frac{D}{T}[/tex]

In this problem:

Then, the probability is:

[tex]p = \frac{D}{T} = \frac{14}{23} = 0.6087[/tex]

0.6087 = 60.87% probability of a puppy having no spots.

the last graph is correct

Step-by-step explanation:

Answer:

$180

Step-by-step explanation:

(12*10)+(12*5)

12*5 = 120/2 = 60 (half of 12*10)

12*10= 120

120 + 60= $180

You don't even have to calculate (12*5) you can just do 12*10/2

Step-by-step explanation:

-7/3 ( 12q + 1/3r + 6 )

multiply each number in the parentheses separately by - 7/3

- 7/3 ( 12q) = - 84/3 q   or  - 28q

- 7/3 ( 1/3r) = - 7/9 r

- 7/3 ( 6) = -42/3  or - 14

Putting back together you get

-28q - 7/9r - 14

Step-by-step explanation:

4100*0.01=41

41*(2/10)=8.2

The equation of perpendicular line is [tex]$y=-\frac{11}{6} x+\frac{43}{6}[/tex].

The equation of the straight line is represented by

y = mx + c

where m is the slope , and c is the intercept on y axis.

Calculate the slope m of BC using the slope formula

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

with [tex]$\left(\mathrm{x}_{1}, \mathrm{y}_{1}\right)=\mathrm{B}(8,4)$[/tex] and [tex]$\left(\mathrm{x}_{2}, \mathrm{y}_{2}\right)=\mathrm{C}(-3,-2)$[/tex]

[tex]$m_{B C}=\frac{-2-4}{-3-8}=\frac{6}{11}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]$m_{\text {perpendicular }}=-\frac{1}{m}=-\frac{1}{\frac{-6}{11}}=-\frac{11}{6}$[/tex], then

[tex]$y=-\frac{11}{6} x+c[/tex]  is the partial equation

To find c substitute A(3,8) into the partial equation

[tex]$9=-\frac{-11}{6}+C[/tex]

[tex]$-\left(-\frac{11}{6}\right)+C=9$$[/tex]

Apply rule -(-a)=a

[tex]$\frac{11}{6}+C=9$$[/tex]

Subtract [tex]$\frac{11}{6}$[/tex] from both sides

[tex]$\frac{11}{6}+C-\frac{11}{6}=9-\frac{11}{6}$$[/tex]

Simplify

[tex]$C=\frac{43}{6}$$[/tex]

[tex]$y=-\frac{11}{6} x+\frac{43}{6}[/tex] be the equation of perpendicular line.

Therefore, the value of c = 43/6.

Answer:

The answer is C, 17 and | -17|

Step-by-step explanation:

We can solve this using the process of elimination.

Looking at the first one, we know that those | | around the 7 mean to find the absolute value. The absolute value is the number of units the number is from zero, and it is always positive. This means that it is saying 7 and -7. Those are opposites, so we know that this isn't right.

17 and -17 are opposites, since the opposite of a positive is a negative.

The last one is the same. 71 and -71 are opposites. That leaves us with C.

Remember that those | | mean to find the absolute value of. -17 is 17 unites from zero. So is 17 the oppostie of 17? No, so these are not opposites, and therefore are our answer.
