Slope = 5-(-3)/-1-1
Slope = 8/-2 = -4
The eq of the function is
y = -4x + 1
The equation in black:
Slope=4/4 = 1
The equation of the function is
y = x - 4
Solving the two equations:
Subtract 1 from 2
-4x +1 - x + 4 = 0
-5x = -5 so x = 1
Replacing in the second equation
y = 1 - 4 = -3

Trey bought 3 and 3 fourths pounds of apples from the grocery store. Corinne bought 1 and 1 third pounds of grapes from the grocery store. How many more pounds of fruit did Trey buy
Answers
Answer: 2 5/12
Step-by-step explanation:
Trey bought 3¾ pounds of apples from the grocery store. Corinne bought 1⅓ pounds of grapes from the grocery store.
To know how many more pounds of fruit that Trey bought, we have to find the difference between the value given above and this will be:
= 3¾ - 1⅓
= 3 9/12 - 1 4/12
= 2 5/12
Trey bought 2 5/12 pounds more.

Find the exact values of sinø , cosø, and tanø if the terminal side of ø in standard position contains the given point.
P(-3,4)
I need sinø, cosø, and tanø please.
Answers
Answer:
See below for answers and explanations
Step-by-step explanation:
Given P(-3,4) we can solve for the third side:
c=√[(-3)²+4²]
c=5
If the terminal side of ø in standard position contains the given point, then it is located at that point, making -3 the opposite side (the side length is 3), 4 the adjacent side, and 5 the hypotenuse.
Therefore:
cos∅=adjacent/hypotenuse=4/5
sin∅=opposite/hypotenuse=3/5
tan∅=opposite/adjacent=3/4

Part A: Mike wants to join a gym. He has to pay an initiation fee of $16 and equal monthly payments for the year. The most he wants to pay is $580 for the year for his gym membership. a.) Write an inequality that you can use to determine the most he would want to spend for his monthly payments.
Part B: Now use your inequality from 15a to determine how much Mike’s monthly gym payment can be if the most he wants to pay is $580 for the year for his gym membership..
Answers
Answer:
Part A: [tex]12x+16\leq 580[/tex]
Part B: $47 per month
Step-by-step explanation:
Part A: 12 months in a year. Pays x amount of $ per year, with an additional $16 initiation fee. He wants to spend less than $580 total a year. Thus, [tex]12x+16\leq 580[/tex].
Part B: Solve the inequality for x.
$580 - $16 = $564
x = $564/12 = $47

The minimum charge for first 175 of telephone calls
is Rs. 300. If the charge of each additional call is Rs.
3.50 , how much will be charge for 389 telephones
calls?
Answers
Answer:
Rs. 1,049
Step-by-step explanation:
Charge for 175 of telephone calls
= Rs. 300
Additional charge per call = Rs.
3.50
how much will be charge for 389 telephones calls?
389 telephones calls - 175 telephones calls = 214 telephones calls
Charge for 389 telephones calls = charge of 175 telephone call + (charge of 389 telephones calls - 175 telephones calls)
= Rs. 300 + charge of 214 telephones calls
= Rs. 300 + 214(Rs. 3.50)
= Rs 300 + Rs. 749
= Rs. 1,049

$8.88
Step-by-step explanation:
24yds needed = 864 inches
864/150 = 5.76 so he'll need 6 spools
6x 1.48 = $8.88
Answer:
$7.40
Step-by-step explanation:
First, take 78% of 24, which is 18.72. So 18.72 yards of ribbon will be blue. Then, convert the number of yards to inches. You can multiply it by 3 to get the number of feet and then that number by 12 to get the number of inches. So you'll have 673.92. Next, figure out how many spools Jordan needs. Divide 673.92 by 150. You get around 4.4, but since you can't buy 0.4 spools, Jordan will need to buy 5 of them.
So multiply 1.48 dollars by 5 spools and you'll get $7.40. Which is how much Jordan spent on blue ribbon.

Andrea uses 9.8 pints of white paint and blue paint to paint her bedroom walls. 1 4 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answers
Answer:
7.35
Step-by-step explanation:
Andrea uses 9.8 pints of white and blue paints to paint her bedroom walls
1/4 of this amount is white paint
= 1/4 × 9.8
= 0.25×9.8
= 2.45
Therefore the amount of blue paint can be calculated as follows
9.8-2.45
= 7.35
Hence 7.35 are blue paint

A chord consists of notes that sound good together. The C major chord, starting at middle C, has the following
frequencies:

E-330 Hz
G-392 Hz
a.
Determine the ratio of the frequency of G to C. Express the answer in a simple integer ratio. (Due to rounding the ratio
will be approximate.) How many G waves will fit in the length of four C waves?
6
b. 5
c. 4
d. 3
Please select the best answer from the choices provided
Answers
Answer:
D. 3
Step-by-step explanation:
I mathed it
Answer:
To determine the ratio of the frequency of G to C, we divide the frequency of G by the frequency of C:
G/C = 392/262
Simplifying the ratio by dividing both numbers by 2, we get:
G/C = 196/131
This is an approximate ratio, since we rounded the frequencies to the nearest whole number.
To find out how many G waves will fit in the length of four C waves, we need to compare the wavelengths of the two notes. The wavelength is the distance between two corresponding points on a wave, such as the distance between two peaks or two troughs.
The wavelength is inversely proportional to the frequency, so we can use the ratio of frequencies we found above to determine the ratio of wavelengths:
λ(G)/λ(C) = f(C)/f(G) = 262/392 = 0.668
This means that the wavelength of G is about 0.668 times the wavelength of C. Since the frequency of G is higher than the frequency of C, we can also say that G has more waves per second than C.
To find out how many G waves fit in the length of four C waves, we need to multiply the wavelength of G by the number of waves in four C wavelengths:
4λ(C)/λ(G) = 4/(λ(G)/λ(C)) = 4/0.668 ≈ 5.988
So, approximately 6 G waves fit in the length of four C waves.
Therefore, the answer is (A) 6
The January record high temperature in Austin, Texas is 92 degrees. The January record low temperature is -1 degree. What is the difference between the record high and low temperatures?
Answers
Answer:
93
Step-by-step explanation:
The forecast high is the highest temperature expected to occur that day, which in most cases is in the afternoon. When referring to the recorded high/low from a previous day, the high and low-temperature values are the actual temperature extremes that were recorded during that 24-hour calendar day.
Given: Texas is 92 degrees. January's record low temperature is -1 degrees.
To find: What is the difference between the record high and low-temperatures?
Solution: Subtract -1 from 92, 92 - (-1) = 93
