# Find the slope for 3, 8 and 7, -7

-3 3/4

Step-by-step explanation:

First, you make a table.

x  |  y

3  |   8

7   |  -7

Since in the table it shows that it goes up 4 x's for every -15 y's, that means for every 1 x it goes down -3.75 y's, so -3.75 (-3 3/4)  is the slope.

Nik, a social worker for a county, helps county residents who are struggling with different issues. Nik logs the following hours meeting with clients (c) or doing other work (o):_______ Mon: 6 c, 4 o
Tue: 8 c, 2 o
Wed: 9 c, 1 o
Thu: 7 c, 3 o
Fri: Off
What percent of time did Nik spend with clients on Thursday?
a. 10%
b. 70%
c. 30 %
d. 80%

Step-by-step explanation:

Given : Nik logs the following hours meeting with clients (c) or doing other work (o) :

Mon: 6 c, 4 o

Tue: 8 c, 2 o

Wed: 9 c, 1 o

Thu: 7 c, 3 o

Fri: Off

The number of hours Nik spend with clients on Thursday = 7 [Number of corresponding to c is 7 in the table]

Total hours he spend in work on Thursday =  7+3 = 10

The percent of time Nik spent with clients on Thursday :

Hence, the Nik spent 70% of his time with clients on Thursday.

Thus , the correct option is b. 70%.

Step-by-step explanation:

Write the slope-intercept form of the equation of each line. 8x + 3y = -9

this is becoming a serious problem. my math teacher CANNOT teach.

Step-by-step explanation:

Slope-intercept form is y = mx + b.

You are given 8x + 3y = -9, so to convert this into slope-intercept form you would solve for y and rearrange the terms (if needed) to follow the format of mx + b.

Start by subtracting 8x from both sides of the equation.

3y = -9 - 8x

Divide both sides by 3 to isolate y.

y = -3 - 8/3x

Rearrange the terms so the "x" variable is first.

y = -8/3x - 3

Determine whether each x-value is a solution (or an approximate solution) of the equation.  log4(3x)=3
a. x≈21.333
b. x=-4
c. x=64/3

Log4(3x) = 3
is the same as:

4³ = 3x
64 = 3x
64 / 3 = 3x / x
x = 64 / 3

x ≈ 21.333

Therefore, c is an exact solution, and a is an approximate solution (not showing all the repeating digits, so it's not exact).
Hope this helps! :)

Two sections of statistics are offered, the first at 8 a.m. and the second at 10 a.m. The 8 a.m section has 25 women, and the 10 a.m. section has 15 women. A student claims this is evidence that women prefer earlier statistics classes than men do. What information is missing that might contradict this claim? Choose the best answer below. A.The professor may be female in one class and male in the other, which could affect the female students class preference.
B. The age and class standing of the students is unknown. Older female students may prefer later classes, so it may be only younger female students who prefer earlier classes.
C. The percentage of female students in the two classes is unknown. There may be more females in the in the 8 a.m. because there are more students in the 8 a.m. class than the lo a.m. class. This claim could be true only if the classes were the same size.
D. No information is missing, this claim is true.

Step-by-step explanation:

Given that two sections of statistics are offered, the first at 8 a.m. and the second at 10 a.m. The 8 a.m section has 25 women, and the 10 a.m. section has 15 women.

Unless we know the total number of persons in the class or number of men in each class we cannot come to any conclusion about this.

C. The percentage of female students in the two classes is unknown. There may be more females in the in the 8 a.m. because there are more students in the 8 a.m. class than the lo a.m. class. This claim could be true only if the classes were the same size.

To compare we must have the percentage of women in each class then only we can come to conclusion.

Mere number of women will not help us to decide.

A cathedral has a large,circular stained glass window. A visitor measures the window and calculates that it has a circumference of 12.56 yards. What is the windows area

First, we find the diameter.
12.56 divided by 3.14 = 4.
4 divided by 2 = 2.
Then, use the formula to calculate the area.
2 times 2 times 3.14 = 12.56 is your area.
In this case, the area and the circumference are the same. Sometimes that is not that case though. Hope it helps! :)

To keep up with rising cost a carpenter needs to increase his \$30.00 per hour rate by 18% what will be his hour rate ?

In order to keep up with rising cost carpenter needs to increase his \$30.00 per hour rate to 35.40 \$.

Explanation:

To keep up with rising cost a carpenter needs to increase his \$30.00 per hour rate by 18%.

So hour rate of carpenter = 30.00 \$

Rate of increase = 18 % = 0.18

New hour rate = Initial hour rate + Rate of increase x Initial hour rate

= 30 + 0.18 x 30 = 30 + 5.4 = 35.40 \$

So in order to keep up with rising cost carpenter needs to increase his \$30.00 per hour rate to 35.40 \$.
