Answer:
a. 41
b. -31
c. 25/3, no
Step-by-step explanation:
when it says find f(14) the number inside the parenthesis is x, so you just plug that number into the equation which in this case is 3x-1. for c it says find the input if the output is 24. so basically the output is f(x) or y and the input is x. so 3x-1 = 24.

Write the linear equation of the line that passes through the points (4,-5) and (-6,5)
Answer:
y = -x -1
Brainliest, please!
Step-by-step explanation:
(4, -5)(-6, 5)
y = mx + b
m = slope, b = y-intercept
m = 10/-10
m = -1
y = -1x + b
We can plug in (4, -5):
-5 = -1(4) + b
-5 = -4 + b
b = -1
y = -x - 1

Point R is on line segment QS
. Given QR=3x−8, QS=3x, and RS=2x, determine the numerical length of RS .
Answer: 8
Step-by-step explanation:
QS = RS + QR
3x = 2x + 3x-8
3x = 5x - 8
8 = 2x
8/2 = x
4 = x
RS = 2x = 2(4) = 8
Ms. Jacobs is a photographer. For each job she charges $135 for the first hour she works and $100 for each additional hour. Ms. Jacobs charged a total of $535 for a job on Friday. Which equation can be used to determine h, the number of additional hours she worked on this job? MI - A 135h + 100 = 535 B 135 + h + 100 = 535 SI - C 135 + 100h = 535 PSA - D 135h = 535 + 100 is
Answer:
The answer is C, 135 + 100h = 535.
Step-by-step explanation:
H can't be multiplied by 135, since that's only for one hour. That value never changes, so it can't be A. It's not B because that implies that she starts out by charging $235 for the first hour, plus the # of additional hours, which doesn't make sense. And it's not D because the total amount of $ that she receives must EQUAL 535, but there is another number on the same side with 535. Therefore, the only answer that remains is C.
P.S. She worked 4 additional hours.
Ajay is on the swim team. He improved his time on
the 50-yard freestyle from 32 seconds to 31 seconds.
What's the percent decrease in his time?
Answer:
5%
Step-by-step explanation
50/32= 1.56yard per second ; 50/31= 1.61 yard per second
1.61-1.56= 0.05* 100= 5%
An airplane heads in the direction of N25°E at 325 mph. A tailwind is blowing in the direction N40°W at 50 mph. What is the actual velocity of the plane?
A) 315.786 mph
B) 349.084 mph
C) 438.064 mph
D) 121860.018 mph
In order to fully understand the actual velocity of the airplane bearing, we've carefully drawn out the sketch.
From the image below, by applying the cosine rule to calculate the actual velocity of the plane from the starting point, we have:
b² = a² + c² - 2ac Cos B
where;
a = 50 mph c = 325 mph∠B = 65° + 50° = 115°b² = (50² + 325²) - (2 × 50 × 325 × Cos 115°)
b² = 2500 + 105625 - (32500 × (-0.4226))
b² = 108125 - (-13734.5)
b² = 121859.5
[tex]\mathbf{b =\sqrt{121859.5 }}[/tex]
b = 349.08 mph
Therefore, we can conclude that the actual velocity of the airplane from its starting point is 349.08 mph.

1. How much interest
will Hannah earn in 4 years if she
deposits $630 in a savings account at
6.5% simple interest?
Answer:
$163.8 more.
Step-by-step explanation:
Let's use the formula Principle × Rate × Time, or PRT to find our simple interest. Let's fill in the blanks. Our principle is $630. Our rate is 6.5% and our time is 4 years. Next, we multiply all this. $630 × 13/200 × 4. Our answer would be 163.8. I hoped this helped.

(b) Four of the interior angles of a 12 sided polygon are each x °. The other angles are 2xº each. Calculate the value of x.
Answer:
Step-by-step explanation:
Sum of all the angles of 12 sided polygon= (n -2)*180
= (12 - 2 )*180 = 10 * 180 = 1800
Four interior angle each of xº + 8 interior angles each of 2xº = 1800
4*x + 8*2x = 1800
4x + 16x = 1800
20x = 1800
x = 1800/20
x = 90°
Answer:
x = 90
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 12 , then
sum = 180° × 10 = 1800
There are 12 interior angles
Given 4 are x, then 8 are 2x , so
4x + 8(2x) = 1800
4x + 16x = 1800
20x = 1800 ( divide both sides by 20 )
x = 90

fill in the dimensions and angle measures . Are the dashed segments parallel ?
Answer:
To see whether or not two lines are parallel, we must compare their slopes. Two lines are parallel if and only if their slopes are equal. The line 2x – 3y = 4 is in standard form. In general, a line in the form Ax + By = C has a slope of –A/B; therefore, the slope of line q must be –2/–3 = 2/3.
At the end of a snowstorm, Katherine had 18 inches of snow on her lawn. The temperature then increased and the snow began to melt at a constant rate of 2.5 inches per hour. Assuming no more snow was falling, how much snow would Katherine have on her lawn 4 hours after the snow began to melt? How much snow would Katherine have on her lawn after t hours of snow melting?
After 4 hours of snow melting, there would be 8 inches of snow with the rate of 2.5 inches per hour Katherine would have on her lawn and after t hours the snow would be = 18 - 2.5*t inches.
In this question, the amount of snow melted is required to calculate to know the amount of snow on the lawn, can be calculated by:
the melted amount = rate of melting × timeGiven:
The total amount of snow = 18 inches
Rate of melting = 2.5 inches
Time = 4 hours
Solution:
The amount melted needs to be calculated first in order to find left snow, therefore, putting values in the formula mention above,
the melted amount = rate of melting × time
the melted amount = 2.5 × 4 inches
the melted amount = 10 inches
Then the final amount would have on the lawn = starting amount−melted snow
= 18−10 inches
= 8 inches
Part b) Snow after t hours:
Starting amount= 18 inches
Melted snow= inches per hour×t
= 2.5×t
= 2.5t
Final amount = starting amount−melted snow
= 18 -2.5t
Thus, the correct answer is - 8 inches and 18 -2.5t

Answer:
1_ 129 , 51
2_ b
3_ 40
Step-by-step explanation:
1_ we can represent the bigger angle with x and smaller one with y
and as given, y is smaller than x by 78
so y = x - 78 (1)
as x + y = 180
we put y as we did in (1)
x + x - 78 = 180
so 2x = 258
so x = 129
and y will be 51
2_ from the figure we find the two angles form one angle = 90 degree
3_ from the defenition of complementary angles
m(c) + m(d) = 90
7r + 5 + 8r + 10 = 90
15r + 15 = 90
r = 5
so m(c) will be equal 7*5 + 5 = 40
