Hello!

The slope intercept form of a line is

y = mx + b

m is the slope
b is the y-intercept

b is -5 so the y-intercept is -5

The answer is -5

Hope this helps!

Answer: 5

Step-by-step explanation: y=4x-5

y=mx+or-b

m=slope and b=y intercept

so the y intercept/b is 5 because it wouldn't be -5 because if it was -5 the equation would look like y=4x+5 because if the y intercept was -5 and the equation is subtracting it wuld be adding because when you have 2 - signs it turn into + sign so your answer is 5

and it wouldnt be 4 or -4 because the y intercept is b in the slope form (y=mx+or-b) and b=5 so you can automatically cross them out!

hope this helps

The diagram shows a parallelogram. work out the value of x

muminat

Answer:

x = 39

Step-by-step explanation:

The opposite angles of a parallelogram are congruent, so

3x - 15 = 2x + 24 ( subtract 2x from both sides )

x - 15 = 24 ( add 15 to both sides )

x = 39

Find the amount in an account if 7,650 is invested at 9.15 percent compounded quarterly for 8 years and 6 months

storchak [24]

We have been given that in an account an amount of 7,650 is invested at 9.15 percent compounded quarterly for 8 years and 6 months.

We will use compound interest formula to find our answer.

$A=Pcdot(1+\frac{r}{n}) ^{nT}$ ,

Where, P= principle amount, A= amount after T years, n= period of compounding and r = interest rate (decimal).

Let us substitute our given values in our formula.

$A=7650(1+\frac{0.0915}{4} )^{(8.5\times4)}$

$A=7650(1+0.022875)^{34}$

$A=7650(1.022875)^{34}$

$A=7650\cdot 2.15758136398$

$A=16505.4974$

Therefore, after 8 years and 6 months our amount will be 16505.497.

Answer:

( 6, pi/6)

Step-by-step explanation:

( 3 sqrt(3), 3)

To get r we use x^2 + y ^2 = r^2

( 3 sqrt(3) )^2 + 3^2 = r^2

9 *3 +9 = r^2

27+9 = r^2

36 = r^2

Taking the square root of each side

sqrt(36) = sqrt(r^2)

6 =r

Now we need to find theta

tan theta = y/x

tan theta = 3 / 3 sqrt(3)

tan theta = 1/ sqrt(3)

Taking the inverse tan of each side

tan ^-1 ( tan theta) = tan ^ -1 ( 1/ sqrt(3))

theta = pi /6

Noa was walking in the forest and measured the circumference of two trees that he found. The first tree measured 37 5/8 inches a

rodikova [14]

Answer:

Step 4: 44 32/24 - 37 15/24= 8 17/24

<u>Here we can finally find out the mistake done by Noa. The result is 7 17/24 and not 8 17/24.</u>

Step-by-step explanation:

1. Let's review carefully all the steps taken by Noa to calculate the difference of the circumferences of the two trees.

Circumference Tree 1 = 37 5/8 inches around

Circumference Tree 2 = 45 1/3 inches around

Step 1: 45 1/3- 37 5/8

The measures are correct, no issues copying them.

Step 2: 45 8/24 - 37 15/24

Noa looked for common denominators

1/3 * 8/8 = 8 /24 is correct; 5/8 * 3/3 = 15/24 is also correct.

Step 3: 44 32/24 - 37 15/24

Noa looked for making the fraction part higher on the left side:

45 8/24 = 44 32/24 is correct because 24/24 = 1

Step 4: 44 32/24 - 37 15/24= 8 17/24

<u>Here we can finally find out the mistake done by Noa. The result is 7 17/24 and not 8 17/24.</u>

MORE PROBABILITY :\ . In a family with family with 4 children, excluding multiple births, what is the probability of having 2 gi

Bond [772]

In order to solve or know the probability of having 2 girls and 2 boys, assumed that a girl is as likely as a girl at each birth, pascal’s triangle will be likely used. And we will be referring to the line 4 of pascal’s triangle, which was 1 4 6 4 1. Then it will look like this: 1 = 4 girls; 4 = 3 girls & 1 boy; 6 = 2 girls & 2 boys; 4 = 3 boys & 1 girl; 1 = 4 boys. And now for the solution in order to get the probability of having 2 girls and 2 boys is to divided into the sum of 1+4+6+4+1.
