PLZ HELP ME WITH THIS ITS DUE SOON AND IDK HOW TO DO IT :(

Answer: b, 12

explanation: combine -3/2 * x and u get -3/2x. then isolate the variable by doing the inverse of subtraction on both sides. (add 9 on both sides). then do the inverse of multiplication on both sides. (divide by -3/2 on both sides)

To solve this system, we will use the graphing method.

Based on the graph shown below, we can conclude that this system has infinite solutions, because they are the same line.

Answer:

Step-by-step explanation:

Given equations

Rewriting the first equation

As we see it is same as the second equation. So same two lines, overlapping when graphed and the system has infinitely many solutions

15 x 2 = 30

12 ÷ 3 = 4

Have a wonderful day!

x (x + 4) = 5

x² + 4x = 5

x²+ x + (-5) = 0

(x+3)²+(t+3)²=9

x² + 6x + 9 + t² + 6t + 9 = 9

x² + t² + 6x + 6t + 18 + (-9) = 0

x² + t² + 6x + 6t + 9 = 0

x² + t² + 6(x + t) + 9 = 0

3/x + 4/2x = x - 1

6/2x + 4/2x = x - 1

10/2x = x - 1

10 = (x - 1) 2x

10 = 2x² - 2x

0 = 2x² + (-2x) + (-10)

Answer:

When it is in parentheses.

Step-by-step explanation:

In PEMDAS, first is always parentheses, no matter what operation.

If it is subtraction, do that first.

hope this helped!

Answer:

the 3rd one

Step-by-step explanation:

this is only true when it is in perenthisis because when you do PEDMAS you go in that order. P (perenthisis) beng first. so TECHNECLY perenthisis is first, but the first actual MATH PROBLEM being done is subtraction.

Answer:

80 cm

Step-by-step explanation:

The diagonals divide the rhombus into four congruent triangles.  The height of each triangle is 18/2 = 9, and the hypotenuse is 41.  Using Pythagorean theorem, the width of each triangle is:

c² = a² + b²

41² = 9² + x²

x = 40

Therefore, the longer diagonal is 2×40 = 80.

Answer:

should be 8.

Step-by-step explanation:

As the picture shows, FG is 8. It also shows that FG and GD are congruent, so they are both equal to 8

Answer: Maximum tickets she can buy is 52

Step-by-step explanation:

After she bought the fries and drinks she was left with $49.81. If she spent the rest of her money on rides/tickets for the rides then she bought 52 tickets to be exact. 0.95x52=49.40

Answer:

There are 2,000 grams left after 300 years.

Step-by-step explanation:

Giving the following information:

The half-life of a radioactive substance is 200 years. There are 8000 grams of the substance initially.

First, we need to calculate the reduction of the substance each year:

Yearly reduction= 8,000/400= 20 grams per year

Now, for 300 years:

300 year reduction= 20*300= 6,000

There are 2,000 grams left after 300 years.

LCM of 8 and 4 = [tex]8[/tex]

LCM of 8 and 6  [tex]=24[/tex]

LCM of 8 and 10 = [tex]40[/tex]

Step-by-step explanation:

Least common multiple (LCM) of numbers is their smallest common multiple.

First find prime factorization of [tex]4,6,8,10[/tex]

[tex]4=2^2\\6=2(3)\\8=2^3\\10=2(5)[/tex]

LCM of 8 and 4 = [tex]2^3=8[/tex]

LCM of 8 and 6  [tex]=2^3(3)=8(3)=24[/tex]

LCM of 8 and 10 = [tex]2^3(5)=8(5)=40[/tex]

▹ Answer

Her dad's swimsuit costs $65.

▹ Step-by-Step Explanation

Since Monica's swimsuit is $35, we will subtract that from the total amount spent, $170.

$170 - $35 = $135

Since Monica's mom's swimsuit costs 2x Monica's we will multiply 35 * 2:

$35* 2 = $70

We will now add Monica's cost and her moms' cost:

$35 + $70 = $105

To find Monica's dads' cost, we will subtract 105 from 170:

$170 - $105 = $65

Her dad's swimsuit costs $65.

Hope this helps!

Answer:

18 gallons of paint could paint 10 classrooms.

Step-by-step explanation:

Given that the school bought 18 gallons of paint, and that each classroom requires 1 4/5 of paint to be painted, to determine how many classrooms can be painted with that amount of paint, the following calculation must be performed:

4/5 = 0.8

1 + 0.8 = 1.8

18 / 1.8 = 10

Therefore, 18 gallons of paint could paint 10 classrooms.

Answer:

b) 18

c) 80.78

Step-by-step explanation:

While we can solve this equation with separation of variables, it isn't necessary.  The coffee is originally at 95°, and the ambient temperature is 18°.  The top right graph is the only one that shows this trend.

As t approaches infinity, y approaches the ambient temperature of 18°.

yₙ₊₁ = yₙ + Δt F(tₙ, yₙ)

yₙ₊₁ = yₙ + 2 (-0.02 (yₙ − 18))

yₙ₊₁ = yₙ − 0.04 (yₙ − 18)

yₙ₊₁ = 0.96 yₙ + 0.72

When n=0:

y₁ = 0.96 y₀ + 0.72

y₁ = 0.96 (95) + 0.72

y₁ = 91.92

When n=1:

y₂ = 0.96 y₁ + 0.72

y₂ = 0.96 (91.92) + 0.72

y₂ = 88.96

When n=2:

y₃ = 0.96 y₂ + 0.72

y₃ = 0.96 (88.96) + 0.72

y₃ = 86.12

When n=3:

y₄ = 0.96 y₃ + 0.72

y₄ = 0.96 (86.12) + 0.72

y₄ = 83.40

When n=4:

y₅ = 0.96 y₄ + 0.72

y₅ = 0.96 (83.40) + 0.72

y₅ = 80.78

Answer:

a.(-1,8), (2,9) b. (2,0) (3,5)

Step-by-step explanation:

a.

for (-4, 7) slope is [tex]\frac{1}{3}[/tex]

slope is m=rise /run =rise 1/run3 so to go to the next point

from (-4,7)

rise 1 so now you are at (-4,8) and run 3 and you are at (-1,8)

from (-1,8)

rise 1 to (-1, 9) and run 3 to (2,9)

b

(1,-5) slope is [tex]\frac{5}{1}[/tex]

from (1,-5) rise 5 to (1,0) and run 1 to (2,0)

from (2,0) rise 5 to (2,5) and run 1 to (3,5)

Answer:

Please check the explanatio.

Step-by-step explanation:

Solving Part b)

We know that the slope-intercept form of the equation line is

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept

Given the equation

[tex]4x+2y=16[/tex]

Re-writing the equation in the slope-intercept form

[tex]4x+2y=16[/tex]

[tex]y=-2x+8[/tex]

Here, m=-2 and b=8

Thus, the equation in the slope-intercept form will be:

[tex]y=-2x+8[/tex]

Solving Part c)

As you sold two pounds of cheddar cheese.

i.e. y=2

substituting y=2 in the slope-intercept form of the line equation

[tex]y=-2x+8[/tex]

[tex]2=-2x+8[/tex]

Subtract 8 from both sides

[tex]-2x+8-8=2-8[/tex]

[tex]-2x=-6[/tex]

Divide both sides by -2

[tex]\frac{-2x}{-2}=\frac{-6}{-2}[/tex]

[tex]x=3[/tex]

You sold 3 pounds of swiss cheese.

Solving Part d)

[tex]y=-2x+8[/tex]

putting x=2.5 in the equation

[tex]y=-2x+8[/tex]

[tex]2=-2\left(2.5\right)+8[/tex]

[tex]2=3[/tex]

The sides are not equal

FALSE

Thus, x=2.5 does not make any sense in the context of the problem.
