can you all help me with this im stuck and imma need some help.

y = mx + b

m = slope or rate of change

b = y-intercept

x = input

y = output

Answer:

x= input

y= output

Step-by-step explanation:

Answer:

y=3/2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5y+ −1/2=7

Step 2: Add 1/2 to both sides.

5y+/−1/2+1/2=7+1/2

5y=15/2

Step 3: Divide both sides by 5.

5y/5

=

15/25

y=3/2

The solution of the given equation is y = 3/2.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operations is called the arithmetic operator.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

We have given the equation as

⇒ 5y - 1/2 = 7

Add 1/2 to both sides in the above equation.

⇒ 5y - 1/2 + 1/2 = 7 + 1/2

⇒ 5y = 15/2

Divide both sides by 5

⇒ y = 15/10

⇒ y = 3/2

Hence, the solution of the given equation is y = 3/2.

Answer:

Manny: 37 years old

Jeremey: 35 years old

David: 30 years old

Step-by-step explanation:

First, we must divide 102 by 3, since there are 3 people in this scenario.

102 ÷ 3 = 34

We know that 34 is an estimate of each person's age, but there's still more work to do.

Manny is seven years older than David:

30 + 7 = 37

Jeremey is 2 years younger than Manny:

37 - 2 = 35

37 + 35 + 30 = 102

Hope this helps! :)

Answer:

This is the given information for which system of equations would be used to find out how many dimes and quarters Amir has?

x = dimes          x = 0.10 or 0.1

y = quarters      y = 0.25

31 coins

worth $5.20       = 5.2

x + y = 31

0.1x + 0.25y = 5.2

Answer:

The width of the garden is 12 feet.

The length of the garden is 20 feet.

Step-by-step explanation:

Let l be the length and w be the width

Then according to given statements

[tex]l = 2w-4\ \ \ Eqn\ 1[/tex]

Second equation is:

[tex]2l+2w = 64\ \ \ \ Eqn\ 2[/tex]

Putting l = 2w -4 in equation 2

[tex]2(2w-4)+2w = 64\\4w-8+2w = 64\\6w -8 = 64\\6w = 64+8\\6w = 72\\\frac{6w}{6} = \frac{72}{6}\\w = 12[/tex]

Putting w = 12 in equation 1

[tex]l = 2(12)-4 = 24-4 = 20[/tex]

Hence,

The width of the garden is 12 feet.

The length of the garden is 20 feet.

Answer:

c = 6

a = 14

l = 28

t = 18

Step-by-step explanation:

Free throws are usually worth one point each. We can assign variables and use equations to link information between Adam, Cheryl, Laura, and Tom. Then, we can just substitute in our information and solve.

"Adam scored 8 more points than Cheryl"

a = c + 8

"Laura scored twice as many points as Adam"

l = 2a

"Tom scored 10 points less than Laura"

t = l - 10

"Together the four friends scored a total of 66 points"

a + c + l + t = 66

Now we substitute in our variables and solve from there (see attached image)

c = 6

a = 14

l = 28

t = 18

Answer:

The time the ball will hit the ground is 1.4s

Step-by-step explanation:

Given;

function of the ball's motion; h(t)= -5t²+ 14t + 3h

The final velocity of the ball, v , is given as;

v = dh/dt

v = -10t + 14

When the ball hits the​ ground, the final velocity, v = 0

v = -10t + 14

0 = -10t + 14

10t = 14

t = 14 / 10

t = 1.4s

Therefore, the time the ball will hit the ground is 1.4s

Answer:

[tex]\boxed {x = 4}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]7x - 21 = x + 3[/tex]

-Take [tex]x[/tex] and subtract it from [tex]7x[/tex]:

[tex]7x - 21 - x = x - x + 3[/tex]

[tex]6x - 21 = 3[/tex]

-Add both sides [tex]21[/tex]:

[tex]6x - 21 + 21 = 3 + 21[/tex]

[tex]6x = 24[/tex]

-Divide both sides by [tex]6[/tex]:

[tex]\frac{6x}{6} = \frac{24}{6}[/tex]

[tex]\boxed {x = 4}[/tex]

Thus, the value of [tex]x[/tex] is [tex]4[/tex].

Answer:

After solving the equation [tex]\frac{x+4}{4}=\frac{x}{x-2}[/tex] we get x=-2 and x= 4 i.e {-2,4}.

Option B is correct.

Step-by-step explanation:

We need to solve [tex]\frac{x+4}{4}=\frac{x}{x-2}[/tex]

Solving:

[tex]\frac{x+4}{4}=\frac{x}{x-2}[/tex]

Cross multiply

[tex](x-2)(x+4)=x*4[/tex]

Multiplying:

[tex]x(x+4)-2(x+4)=4x\\x^2+4x-2x-8=4x\\x^2+2x-8-4x=0\\x^2-2x-8=0[/tex]

Now, we have got quadratic equation [tex]x^2-2x-8=0[/tex]

Solving this quadratic equation using quadratic formula

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\[/tex]

We have a=1, b=-2 and c=-8 Putting values

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-(-2)\pm\sqrt{(-2)^2-4(1)(-8)}}{2(1)}\\x=\frac{2\pm\sqrt{4+32}}{2}\\x=\frac{2\pm\sqrt{36}}{2}\\x=\frac{2\pm6}{2}\\x=\frac{2+6}{2} \ or \ x=\frac{2-6}{2}\\x=\frac{8}{2} \ or \ x=\frac{-4}{2}\\x=4 \ or \ x=-2[/tex]

So,after solving the equation [tex]\frac{x+4}{4}=\frac{x}{x-2}[/tex] we get x=-2 and x= 4 i.e {-2,4}.

Option B is correct.

Answer: D) All real numbers greater than or equal to -4.

Explanation:

The lowest point occurs when y = -4, which is where the vertex is located.

The range consists of y values such that y = -4 or y > -4. We can shorten that last sentence to say [tex]y \ge -4[/tex]. So y is greater than or equal to -4.

As you can probably tell, the range is the set of all possible outputs of a function.

Answer:

[tex]-2^{\circ}\text{F}[/tex]

Step-by-step explanation:

Let [tex]x[/tex] be the temperature on the first day

Second day temperature

[tex]x+7[/tex]

Third day temperature

[tex]x+7-10[/tex]

Fourth day temperature was [tex]1^{\circ}\text{F}[/tex]

[tex]x+7-10+6=1\\\Rightarrow x+3=1\\\Rightarrow x=1-3\\\Rightarrow x=-2^{\circ}\text{F}[/tex]

On the first day the temperature was [tex]-2^{\circ}\text{F}[/tex]

Answer:

1st choice Music Equation: [tex]\$(x+5)[/tex]

Superstar Music Club Equation: [tex]\$3.50x[/tex]

Solution: 2

Step-by-step explanation:

Given that:

1st choice music club:

Charges for one song = $1

Charges for sign - up = $5

Let the number of songs = [tex]x[/tex]

Total cost = [tex]\$5+\$1\times x = \$(x+5)[/tex]

Superstar music club:

No sign up fee and

Charges for one song = $3.50

Total cost = [tex]\$3.50x[/tex]

Given that, cost of each music club becomes equal:

Putting them same:

[tex]x+5=3.5x\\\Rightarrow 2.5x = 5\\\Rightarrow \bold{x =2}[/tex]

After 2 songs, the cost of both the clubs will become equal.

Answer:

x = 50

Step-by-step explanation:

these are vertical angles meaning they are congruent so

[2(x+10)] = (3x-30) then use distributive property

(2x+20) = (3x-30) subtract 2x from both sides

20 = x - 30 add 30 to both sides

x = 50

Answer:

x = 50

Step-by-step explanation:

We know that 2(x+10) = (3x-30) because it is on opposite sides of an "x".

We just set them equal to each other and solve for x!

2(x+10) = 3x - 30

2x + 20 = 3x - 30

20 = x - 30

50 = x

Given:

Total debt ratio (total debt to total assets) = 0.365

Total debt = $500,000

To find:

The total assets.

Solution:

We know that,

[tex]\text{Total debt ratio}=\dfrac{\text{Total debt}}{\text{Total assets}}[/tex]

On substituting the given values, we get

[tex]0.365=\dfrac{500,000}{\text{Total assets}}[/tex]

[tex]\text{Total assets}=\dfrac{500,000}{0.365}[/tex]

[tex]\text{Total assets}=1369863.0137[/tex]

Therefore, the value of total assets is $1369863.0137.

Answer:

y=1x+1

Slope is 1

Step-by-step explanation:

Slope = rise/run.

We go up 1 and run 1. The slope is 1.

Let me double check.

The line passes through the points (-1,0) and (0,1).

m = delta y ÷ delta x

m = (0 - 1)/(-1 - 0)

m = -1/-1

m = 1

Yep. The slope is 1.
