suppose a+b=10 and the value of a increases by 1. If the sum remains the same, what must happen to the value of b?

Answers

Answer:

[tex]b[/tex] decreases by [tex]1[/tex]

Step-by-step explanation:

If the value of [tex]a[/tex] increases by [tex]1[/tex] and the sum remains the same, then the value of [tex]b[/tex] decreases by [tex]1[/tex].

Example:

Suppose [tex]a=7[/tex] and [tex]b=3[/tex].

[tex]a+b = 10[/tex]

[tex]b = 10-a[/tex] (minus [tex]a[/tex] on both sides)

Now, let [tex]a = 8[/tex] ([tex]a[/tex] has increased by [tex]1[/tex]):

[tex]b = 10-8[/tex]

[tex]=2[/tex]

From the comparison of the previous value of [tex]b[/tex] to the current value of [tex]b[/tex], the value of [tex]b[/tex] has decreased by [tex]1[/tex].

Carson is a high school student with two part-time jobs. He earns $6 per hour for babysitting, and he earns $8 per hour doing clerical work for his father's business. His goal is to earn at least $96 a week, but because of school, he does not want to work more than 15 hours each week. Suppose Carson worked as a babysitter for 5 hours one week. What is the minimum number of full hours he would need to work at his father's business to earn at lease $96 that week?

Answers

Step-by-step explanation:

Step one:

let the hours for babysitting be x

and the hours for doing clerical be y

we are told that Carson would like to earn $96 weekly

She babysits for $6 per hour

and earned $8 per hour doing clerical work

6x+8y=96---------------1

Carson cannot work more than a total of 15 hours per week

5x+y≤15-------------2

The system of equation for the situation is

6x+8y=96

5 x+y≤15

y=15-5 x

put y=15-5 x in eqn 1

6x+8(15-5 x)=96

6x+120-40x=96

collect like terms

6x-40x=96-120

-34x=-24

x=24/34

x=0.7

Approximately 1 hour babysitting

put x= 0.7 in 5x+y≤15

5(0.7)+y≤15

3.52+y≤15

y≤15-3.52

y=11.4

Approximately 11 hours doing clerical work

can someone help me plz 2a+1=1

Answers

Answer:

Step-by-step explanation:

2a+1=1

2a=0

--- ---

2 2

a=0

Answer:

A=0

Step-by-step explanation:

2a+1=1

2a=1-1 (i moved +1 to the other side ...coz our goal is to isolate "a", and in order to do this, look for numbers that are freer)(moving the +1 to the other side made it -1)(you just need to remember that when we move any number to the other side it will claim its opposite operation so +1 will turn to -1)

2a=0 (1-1=0)

a=0/2 (now, 2 is being multiplied with a, and to isolate "a" we move 2 to the other side, and this will make to divide ((because the opposite of multiplication is division)) )

a=0 (the ans!)

Either Table A or Table B shows a proportional relationship.

Table A

x −2 −1 0 1
y 2 3 0 5

Table B

x −1 0 1 2
y −3 0 3 6

Plot the points from the table that shows a proportional relationship.

Answers

Answer:

the answer is table B

Step-by-step explanation:

Answer:

Table B shows a proportional relationship

Explanation:

In a proportional relationship two quantities vary directly with each other.

So,

y ∝ x

y = kx

Where, k is the constant of variation.

The ordered pairs of table A are (-2,2), (-1,3), (0,0) and (1,5).

From these ordered pairs we can conclude that the value of y-coordinate is not changing according to the x-coordinate because the values of x increased by 1 for each ordered pair but the value of y is not increasing in the same proportion..

The ordered pairs of table B are (-1,-3), (0,0), (1,3) and (2,6). The value of y increasing at a constant rate 3 and the value of y-coordinate is 3 times of x-coordinate.

Choose any two ordered pairs of table B. Let the two points are (0,0) and (1,3).

The proportional relationship is defined as

y = 3x

Therefore, 3 is the constant of variation and rate of change.

So, Table B shows a proportional relationship.

Read this excerpt from President Ronald Reagan's Address to the Nation following the explosion of the Challenger space shuttle. I've always had great faith in and respect for our space program, and what happened today does nothing to diminish it. We don't hide our space program. We don't keep secrets and cover things up. We do it all up front and in public. That's the way freedom is, and we wouldn't change it for a minute. We'll continue our quest in space.

Emma Abrams choked with deep conviction. "You mean everything to me. I can't live without you!" This was the part of the script where Emma was supposed to burst into real tears, yet her big blue eyes were like a desert. Emma tried to think of something despairing, like the time her toddling brother sliced his finger on a piece of broken glass while she was watching him, or the devastation she felt when learning that her cat had run away. These sad reflections did nothing to moisten her eyes. "Well, don't panic, Emma," she coached herself. "When it counts in the audition today, you'll cry real tears. You've just got to!"2It was difficult to study the script in the car with all of the bumps, turns, and sudden stops typical of trips into New York City, but Emma was determined to make sure that she had each line memorized word for word. She had studied every line nonstop since her agent had called with the good news. It was her first Broadway audition and her entire family had helped her to prepare. Her older sister helped her choreograph a dance, her father improvised with her by playing the part of Grandpa at the dinner table, and her little brother listened to her read her lines. No one was more constant in helping Emma realize her thespian ambitions than her mother, though. Mom was the one who accompanied Emma to her piano, voice, dance, and drama lessons each weekday after school. She went to every audition and performance with Emma, and Emma wished with all her heart that Mom was here with her now.3Emma appreciated her mother's constant companionship and support of her acting career. Her mother was always present backstage at the Dutch Apple Dinner Theater where Emma was currently starring in Annie on Friday and Saturday nights. Mom was the driving force behind her daughter's acting career, but she refused to drive in New York City. The big city frightened Mrs. Abrams and made her jittery. Since she was already nervous about Emma's big audition, Mrs. Abrams thought it best if she just stayed home. Emma tried to behave like a grown-up when her mother told her she wouldn't be going, but inside Emma felt panicky and alone.4Emma's father continued to navigate through the heavy traffic streaming into the city. As the skyline of New York City came into view, Emma started to cry. She knew she should have begged her mother to come with her but now it was too late! Her father looked into the rearview mirror and said, "Wow, honey! If you can do that during the audition, you're a shoo-in." He was genuinely impressed and didn't realize that her tears were real. Emma stared out the window, feeling sorry for herself.5Emma watched her dad hand his car keys to the parking attendant. They walked in silence for several blocks, with Emma holding her father's arm. She wanted to ask her father to come in to the audition with her, but she knew he'd be uncomfortable around a bunch of stage mothers. Emma soon found herself being escorted into a crowded lobby. She waved good-bye to her father and disappeared inside the theater.6When she emerged from the audition several hours later, Emma was exhausted but triumphant. "I don't ever want Mom to come to an audition where I have to cry again!" she declared as they left the theater together.7Knowing his daughter's flair for the dramatic, Mr. Abrams quickly said, "Now don't be angry with your mother because she couldn't come today, Emma. That's not fair."8Emma realized her father misunderstood her, so she explained that when she'd cried in the car earlier, it wasn't an act; she was genuinely upset that her mother wasn't with her. "When I went into the audition, all the other girls' mothers were there, but I was all alone. I was terrified without Mom there, so when they called on me to read my lines, I was on the verge of tears anyway. I just thought about how alone I felt without Mom there, and the tears came pouring down. It was perfect timing, and I think I just might get the part! Mom is the secret to my success." She bowed and curtsied to an imaginary audience, saying "Thank you, Thank you."9Mr. Abrams smiled and said, "I'm not sure, but I think that just this once, your mother will be extremely happy to hear that she made you cry."How does the resolution of the story develop the theme? A. Emma was able to make herself cry with hard work and dedication. B. Emma finally realized she did not need anyone else to be successful. C. Emma concluded that her father was just as supportive as her mother. D. Emma understood that it was not right for her to be angry with her mother.
