Answer:

y = 5/4x + 10

Step-by-step explanation:

First, we need to use point-slope form which is:

y - y₁ = m(x - x₁)

Now, we substitute the numbers:

y - 5 = 5/4(x - (-4))

y - 5 = 5/4(x + 4)

y - 5 = 5/4x + 5

y = 5/4x + 10

You can check by substituting the points into the equation:

5 = 5/4(-4) + 10

5 = -5 + 10

5 = 5

Answer:

$275

Step-by-step explanation:

30% + 15%=45%

45% of 500 is 225, because 500 x 0.45=225. Then subtract the discount from the total, 500 - 225, and you get 275

OPTION A = 7/24

Answer:

-2

Step-by-step explanation:

Let's solve your equation step-by-step.

−(3v+1)+7(6v+6)=−37

Step 1: Simplify both sides of the equation.

−(3v+1)+7(6v+6)=−37

−3v+−1+(7)(6v)+(7)(6)=−37(Distribute)

−3v+−1+42v+42=−37

(−3v+42v)+(−1+42)=−37(Combine Like Terms)

39v+41=−37

39v+41=−37

Step 2: Subtract 41 from both sides.

39v+41−41=−37−41

39v=−78

Step 3: Divide both sides by 39.

Answer:

47.5

Step-by-step explanation:

47.5=100%

57=120%

The input value is 47.5 when the output is 57.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

When the output is 120%, the input is 100%.

And the output is 1.2 times the input.

So, we have the output 57.

To find the input number:

Use division process,

The required number = 57 /1.2

The required number = 47.5.

Therefore, the number is 47.5.

$126

Step-by-step explanation:

$252/$18=$14 dollars per hour.

now take 14*9 and you get $126.

Answer:

$126

Step-by-step explanation:

Okay, so to solve this question, we need to get from 18 (hours) to 9. To do this, we obviously divide 18 by 2. Since we did this, we now have to do the same thing with the other side ($252.) 252 divided by 2 is 126. This means that if Chau made $252 in 18 hours,  he will make $126 in 9 hours.

y=3-2x/x

Answer:

[tex]y = - \frac{3}{ x} + 2[/tex]

Step-by-step explanation:

So we want y to be on a side by itself.

2x-xy=3

Subtract 2x from each side

-xy=3-2x

divide each side by -x

Answer:

The ball will hit the ground at 10 seconds and its maximum height is 1024 feet.

Step-by-step explanation:

Height of a mountain, h = 90 feet

Upward velocity of a ball, u = 64 ft/s

Its height as a function of time can be written by using the second equation of motion as follows :

[tex]f(x) = -16t^2 + 64t + 960[/tex] .....(1)

When it will hit the ground, f(x) = 0

[tex]-16t^2 + 64t + 960=0\\\\16(-t^2+4t+60)=0\\\\-t^2+4t+60=0[/tex]

It is quadratic equation.

t = -6 s and t = 10 s

Neglecting -6 seconds, the ball will hit the ground at 10 seconds.

For maximum height,

Put f'(x) = 0

[tex]-32t+64=0\\\\\\t=\dfrac{64}{32}\\\\t=2\ s[/tex]

Put t = 2 in equation (1)

[tex]f(2) = -16(2)^2 + 64(2) + 960\\\\=1024\ \text{feet}[/tex]

Hence, the ball will hit the ground at 10 seconds and its maximum height is 1024 feet.

Answer:

b=(3a/(2h)), x=(y-b)/m

Step-by-step explanation:

Simply isolate b ;

a=2/3bh, Divid both sides by 2/3 and h

a/(2/3h)=b, simplify

b=(3a/(2h))

Simply isolate x;

y=mx+b; subtract b from both sides and divide by m

y-b=mx

(y-b)/m=x

Answer: #3

Step-by-step explanation:

Answer: 8%

Step-by-step explanation:

Original Perimeter of the rectangle is:

= 2 * ( Length * Width)

= 2 * (20 + 30)

= 100 cm

The length increased by 10%. It therefore increased to:

= 30 * ( 1 + 10%)

= 30 * 1.1

= 33 cm

The width increased by 5%. It increased to:

= 20 * ( 1 + 5%)

= 21 cm

New Perimeter is therefore:

= 2 * ( 33 + 21)

= 108 cm

Percentage increase in perimeter is:

= (New perimeter - old) / old perimeter

= (108 - 100) / 100

= 8%

Answer:

x = 4

Step-by-step explanation:

x + 4(x+5) = 40 (Given)

x + 4x + 20 = 40 (Distribute the 4 into the x and 5)

5x + 20 = 40 (Add like terms)

5x = 20 (Subtract 20 on both sides)

x = 4 (Divide 5 on both sides)

Answer:

x=-1

Step-by-step explanation:

4(x-3(-2))=6(x-3(-2)) => 4(x+6)=6(x+6) => 4x+24=6x+26 => -2=2x => x=-1

Answer:

O1: b) linear, proportional

O2: a) linear, non-proportional

O3: c) nonlinear

Step-by-step explanation:

Recall that a proportional function can be drawn as a straight line (linear function) through the origin (0,0).

O1 is a proportional function since it is linear and goes through the origin.

O2 has a y-intercept of y = 5; therefore, it is not proportional because it does not go through the origin (0,0), although it is linear.

O3 resembles a quadratic function, which means it's not a linear function (nonlinear).

Answer:

Step-by-step explanation:

Answer:

No possible solution

Step-by-step explanation:

Let:

Shirt = x

Pant = y

x + y = 9 - - - - - - - - - (1)

38x + 38y = 222 - - - (2)

From (1):

y = 9 - x

Put y = 9 - x in (2)

38x + 38(9 - x) = 222

38x + 342 - 38x = 222

Based on the Given parameters, we can conclude that the equation does not have a possible solution.
