if y = 2x + 7 were changed to y = 1/2 x + 7 , how would the graph of the new function compare with the original ?

Answers

Answer 1

y = 2x + 7.....the slope is 2 and the y int is 7
y = 1/2x + 7...the slope is 1/2 and the y int is 7

In comparison, the only difference is the slope. And if the original equation has a slope of 2, and it is changed to a slope of 1/2, then it will have a " less steep " slope. In other words, the slope will not be as steep....but the y intercepts will be the same.

Answer 2

Final answer:

The change from y = 2x + 7 to y = 1/2 x + 7 alters the slope, making the new function's graph less steep. The y-intercept remains at y = 7, ensuring the graphs coincide at this point.

Explanation:

The question asks how the graph of the function y = 1/2 x + 7 would compare to the graph of the original function y = 2x + 7. The key difference between these two functions is the slope part, which is the coefficient of x. In the original function, the slope is 2 indicating a rise of 2 on the vertical (y) axis for every increase of 1 on the horizontal (x) axis. But in the new function, the slope is 1/2, indicating a rise of only 1/2 on the y-axis for each increase of 1 on the x-axis. So, the new function's graph would be less steep than the original's. The y-intercept for both functions remains the same, at y = 7. These changes illustrate how the slope and y-intercept of the line equation (y = mx + b) determine the shape and position of the line on the graph.

a7=7/2[2(13)+(7-1)(3)]=7/2(44)=154

Ans:C

Answer:

C. 154

Step-by-step explanation:

Here we have given that,

First Term a₁ = 13

Common Difference d = 3

Term (n ) = 7

so, we have arithmetic sequence: 13, 16, 19, 22,... and so on

Thus Sum of first 7 terms = [tex]\frac{n}{2} [2a+(n-1)d][/tex]

= 7÷2 [2*13 + (7 - 1)*3 ]

= 3.5 [ 26 + 21 ]

Answers

now we sub
y - (-7) = 2/5(x - (-4)...not done yet
y + 7 = 2/5(x + 4) <===

Answer:

Correct option is:

y+7=2/5(x+4)

Step-by-step explanation:

The point-slope form of the line with slope m and passing through the point (x1,y1) is given by:

y-y1=m(x-x1)

Here, we are given line with slope m=2/5

and passing through (x1,y1)=(-4,-7)

i.e. x1= -4 and y1= -7

[tex]y-(-7)=\dfrac{2}{5}(x-(-4))[/tex]

[tex]y+7=\dfrac{2}{5}(x+4)[/tex]

Hence, Correct option is:

Mrs. Kuss received a $50 Itunes gift card for her birthday. She bought one album for $9.99 and would like to see how much money she has left to buy single songs. If each song costs $1.29, how many songs can Mrs. Kuss buy with her remaining money? Show your work.

Answers

Mrs kiss can buy about 31 songs

50.00-9.99 = 40.01
40.01 / 1.29 = 31.0

She initially has $50 and she bought an album of $9. 99 so you subtract those $9.99 from $50 and you are left with $40.01, now you can either divide it by $1.29 to skip the long process or subtract $1.29 at a time. Once you do so, you will get an answer of 31 more songs with $0.02 left. YOU'RE WELCOME :D

A packet of biscuits has a mass of 1 1/3 kg. Jason eats 2/5 of the packet. What is the mass of biscuits left?

Answers

11 / 3 = 55 / 15;
2 / 5 = 6 / 15;
So. 11 / 3 - 2 / 5 = 55 / 15 - 6 / 15 = 49 / 15 = 3.26 kg is the mass of biscuits left.

The mass of biscuits left after Jason eats 2/5 of the packet is approximately 0.8 kg.

To find the mass of the biscuits left after Jason eats 2/5 of the packet, we need to calculate the mass of the biscuits he ate and then subtract it from the initial mass of the packet.

Given:

Mass of the packet of biscuits = 1 1/3 kg

First, let's convert 1 1/3 kg to an improper fraction:

1 1/3 = 3/3 + 1/3 = 4/3 kg

Now, to find the mass of the biscuits Jason ate, we can use the fact that he ate 2/5 of the packet:

Mass of biscuits Jason ate = (2/5) * (4/3) kg

Now, perform the multiplication:

Mass of biscuits Jason ate = (8/15) kg

To find the mass of biscuits left, we subtract the mass Jason ate from the initial mass of the packet:

Mass of biscuits left = 4/3 kg - 8/15 kg

To subtract fractions, we need to find a common denominator, which is 15 in this case:

Mass of biscuits left = (20/15) kg - (8/15) kg

Now, perform the subtraction:

Mass of biscuits left = 12/15 kg

Finally, let's simplify the fraction:

Mass of biscuits left = (12/15) * (1/3) kg

Mass of biscuits left ≈ 0.8 kg

Therefore, the mass of biscuits left after Jason eats 2/5 of the packet is approximately 0.8 kg.

Answer: The original area of the square is 64 square feet

-------------------------------------
-------------------------------------

Let x be the original side length of the square. The original area is therefore going to be x*x = x^2. For now we don't know the area but once we figure out x, we can compute the area.

The original side length x is increased by 7 ft to jump up to (x+7) ft
At the same time, the other dimension is reduced to (x-2) ft, which is a decrease of 2 ft

The old square is x ft by x ft with area x*x = x^2

The new rectangle is (x+7) ft by (x-2) ft

Let's find the area of this rectangle

Have a look at the image attachment to see how to multiply out (x+7)*(x-2) using the box method

The terms in red are x^2, 7x, -2x and -14 which are found by multiplying the headers

x times x = x^2
x times 7 = 7x
-2 times x = -2x
-2 times 7 = -14

The like terms are 7x and -2x which combine to 5x

Overall the result of multiplying out (x+7)*(x-2) is x^2+5x-14

Note: we can get the same result if we use the FOIL or distribution rule. The box method is a handy way to visually keep track of all the terms.

-------------------------------------

The area of the rectangle, in terms of x, is x^2+5x-14

We are told that the area is 90 square feet

So equate the two expressions and solve for x

x^2+5x-14 = 90
x^2+5x-14-90 = 90-90
x^2+5x-104 = 0
(x-8)(x+13) = 0 ... see note below
x-8 = 0 or x+13 = 0
x = 8 or x = -13

note: find two numbers that multiply to -104 and add to 5. Those numbers are -8 and 13 which helps us factor

We ignore x = -13 as a negative side length makes no sense

The only practical root is x = 8

The side length of the original square is 8 feet

The area is
x*x = 8*8 = 64 square feet

We can check the answer by adding 7 to 8 to get 15, and subtracting 2 from 8 to get 6. The 8 by 8 square turns into a 15 by 6 rectangle. Since 15*6 = 90, we have confirmed the right answer.

Johnny is reading a novel for the read-a- Thon. The ratio of the number of pages she read to the pages that remain to be read is 7:3. If the book contains 500 pages in all, how many pages did Johnny reed and how many pages remain left?

Answers

There are several ways to answer this question and I will use this approach. Since Johnny reads at a ratio of 7:3 it can be stated that for every 10 pages in a book containing 500 pages Johnny will read 7 of those pages. There are 50 groups of 10 in a 500-page book (50 x 10). Take the ration 7:3 times 50 and use the distributive property: 7:3(50) = (7 x 50):(3 x 50) = 350:150. Based on this Johnny has read 350 pages and has 150 pages remaining.

A trail is 2940 miles long. it begins in city a and ends in city
b. manfred has hiked three sevenths 3 /7 of the trail before. how many miles has he hiked?

Answers

Final answer:

Manfred has hiked 1260 miles of the trail, which is calculated by multiplying the total length of the trail (2940 miles) by the fraction of the trail he has completed (3/7).

Explanation:

To calculate the distance Manfred has hiked on the trail, we multiply the total length of the trail by the fraction of the trail he has completed. In this case, Manfred has hiked three sevenths (3/7) of the trail. The total distance of the trail is 2940 miles.

Distance Hiked = (Total Distance of Trail) × (Fraction of Trail Completed)

Distance Hiked = 2940 miles × (3/7)

Distance Hiked = 2940 miles × 0.4286

Distance Hiked = 1260 miles

Therefore, Manfred has hiked 1260 miles of the trail.
