Answer:

$y=7x - 5$ is in slope intercept form

Step-by-step explanation:

$\frac{1}{2}(2y+10)= 7x$

We need to write the equation in slope intercept form

Slope intercept form of the equation is $y=mx+b$

where m is the slope and b is the y intercept

To get the equation in slope intercept form we need to get y alone

$\frac{1}{2}(2y+10)= 7x$

Multiply 1/2 inside the parenthesis

$y+5 = 7x$

To get y alone , subtract 5 from both sides

$y=7x - 5$ is in slope intercept form

Working alone, kali can pick forty bushels of apples in 15 hours,l. One day her friend Natalie helped her and it only took 6 hou

cluponka [151]

Answer:

The time it will take Natalie to pick the forty bushels alone is 10 hours

Step-by-step explanation:

The time it takes Kali to pick forty bushels of apples alone = 15 hours

The time it takes Kali and Natalie to pick forty bushels = 6 hours

The rate at which Kali picks bushels = 40/15 bushels per hour = 8/3 bushels per hour

Let x represents the rate at which Natalie picks bushels, we have;

8/3 × 6 + x × 6 = 40

x × 6 = 40 - 8/3 × 6 = 24

x = 24/6 = 4

Therefore;

The rate at which Natalie picks the bushels of apples = 4 bushels/hour

The time it will take Natalie to pick the forty bushels alone = (40 bushels)/(4 bushels/hour) = 10 hours.

for 2nd week= 2¢

for 3rd week= 4¢

for 4th week=8¢

for 5th week=16¢

for 6th week=32¢

for 7th week=64¢

for 8th week=64+64=128¢

for 9th week= 128+128=256¢

for 10th week= 256+256=512¢

.: he saved a total of

1+2+4+8+16+32+64+128+256+512=1023¢

1023¢=1023/100=$10.23

Jamie has a board that is 8 feet long. He cuts the board into three equal pieces. How long is each piece

Sav [38]

So picture a 8feet long board, and you basically cut it into 3 equal pieces as it says. so you should set it up as 8/3 which is 2.6666666. so you can round that up by 2.67 per each equal pieces.

Given the function f(x) = -5x + 1 + 3, for what values of x is f(x) = -12?

irina1246 [14]

Answer:

$x=\frac{16}{5}$

Step-by-step explanation:

The given function is

$f(x) = -5x +1+3$

Which can be rewritten also as

$f(x) = -5x +4$

We want to find the values of x for which

$f(x) = -12$

In order to do that, we just substitute -12 into f(x), and we solve the equation for x:

$-12 = -5x + 4\\-16 = -5x\\x=\frac{-16}{-5}=\frac{16}{5}$
