Which equation has no solution?


A. −6|x|=−18

B. −5|x|=25

C. 6|x|=0

D. 5|x|=5

I'm not too sure but I think it's option

1. No, because only one angle of the triangle is congruent.

Answer:

The correct Option is Option A

Account B because the principal of Account B is $300 and the principal for Account A is $150

Step-by-step explanation:

Interest earned from Account A = $ 4.50

Interest earned from Account B = $22.50

Time t = 18 months

Interest rate for Account A = 2%

Interest rate for Account B = 5%

We need to find which account has greater principal

The formula used to calculate principal is: [tex]Interest=Principal\times r \times t[/tex]

where r is rate and t is time

Finding Principal for Account A:

Interest earned from Account A = $ 4.50

Time t = 18 months = 1.5 years

Interest rate for Account A = 2% = 0.02

Putting values and finding Principal

[tex]Interest=Principal\times r \times t\\4.50=Principal\times0.02\times1.5\\Principal=\frac{4.50}{0.02\times1.5} \\Principal=\frac{4.50}{0.03} \\Principal=150[/tex]

So, The Principal Amount for Account A = $150

Finding Principal for Account B:

Interest earned from Account B = $ 22.50

Time t = 18 months = 1.5 years

Interest rate for Account A = 5% = 0.05

Putting values and finding Principal

[tex]Interest=Principal\times r \times t\\22.50=Principal\times0.05\times1.5\\Principal=\frac{22.50}{0.05\times1.5} \\Principal=\frac{22.50}{0.075} \\Principal=300[/tex]

So, The Principal Amount for Account B = $300

So, the correct Option is Option A

Account B because the principal of Account B is $300 and the principal for Account A is $150

Answer:

Sheet metal costs $20 per square foot.

Step-by-step explanation:

7.6x - 2.3x = 106

We are finding the value of x.

5.3x = 106

Divide both sides by 5.3.

x = 106 ÷ 5.3

x = 20

                                       Answer and Explanation

__________________________________________________________

__________________________________________________________

Sheet metal costs 20 dollars per square foot, and we can figure this out by multiplying the 20 by the numbers and subtracting them.

__________________________________________________________

[tex]7.6x-2.3x=106[/tex] but what does x equal? ( 20 )

[tex]7.6\cdot20[/tex] = [tex]152[/tex]

[tex]2.3\cdot20[/tex] = [tex]46[/tex]

__________________________________________________________

[tex]152-46[/tex] = [tex]106[/tex]

Which is the same in the question, so x = 20.

You would take 19% of 30.12$ by doing 30.12x0.19 to get 5.72.

you then add 5.72 to 30.12 to get your total of 35.84$

Answer:

decrease

Step-by-step explanation:

Answer:

decrease

Step-by-step explanation:

Given:

[tex]\cos^4 \alpha+\sin^4\alpha=\dfrac{1}{4}(3+\cos 4 \alpha)[/tex]

To prove:

The given statement.

Proof:

We have,

[tex]\cos^4 \alpha+\sin^4\alpha=\dfrac{1}{4}(3+\cos 4 \alpha)[/tex]

[tex]LHS=\cos^4 \alpha+\sin^4\alpha[/tex]

[tex]LHS=(\cos^2 \alpha)^2+(\sin^2 \alpha)^2[/tex]

[tex]LHS=(\cos^2 \alpha+\sin^2\alpha)^2-2\sin ^2\alpha\cos^2 \alpha[/tex]     [tex][\because a^2+b^2=(a+b)^2-2ab][/tex]

[tex]LHS=(1)^2-2(1-\cos^2 \alpha)\cos^2 \alpha [/tex]      [tex][\because \cos^2 \alpha+\sin^2\alpha=1][/tex]

[tex]LHS=1-2\cos^2 \alpha+2\cos^4 \alpha [/tex]

Now,

[tex]RHS=\dfrac{1}{4}(3+\cos 4 \alpha)[/tex]

[tex]RHS=\dfrac{1}{4}[3+(2\cos^2 2\alpha-1)][/tex]        [tex][\because \cos 2\theta=2\cos^2\theta -1][/tex]

[tex]RHS=\dfrac{1}{4}[2+2\cos^2 2\alpha][/tex]

[tex]RHS=\dfrac{1}{4}[2+2(2\cos^2 \alpha-1)^2][/tex]        [tex][\because \cos 2\theta=2\cos^2\theta -1][/tex]

[tex]RHS=\dfrac{1}{4}[2+2(4\cos^4 \alpha-4\cos \alpha+1)][/tex]        [tex][\because (a-b)^2=a^2-2ab+b^2][/tex]

[tex]RHS=\dfrac{1}{4}[2+8\cos^4 \alpha-8\cos \alpha+2][/tex]

[tex]RHS=\dfrac{1}{4}[4+8\cos^4 \alpha-8\cos \alpha][/tex]

[tex]RHS=1+2\cos^4 \alpha-2\cos \alpha[/tex]

[tex]RHS=1-2\cos^2 \alpha+2\cos^4 \alpha [/tex]

[tex]LHS=RHS[/tex]

Hence proved.

Answer:

x≥25

Step-by-step explanation:

Step one:

given data

Jaxon must sell at least 49 rolls of wrapping paper to support the robotics club fundraiser

We are told that he has already sold 24 rolls of wrapping paper.

Step two:

let x be the number of rolls remaining to be sold,

hence,

x≥49-24

x≥25

Therefore the inequality for the situation is  x≥25

which reads that x must be greater than or equal to 25

Answer:

Step-by-step explanation:

.6(2k-3)=3(4k+5) foil

1.2K-1.8=12k+15 subtract 1.5k from both sides

-1.8=10.8k+15 subtract 15 from both sides

-16.8=10.8k divide by 10.8

k= -1.5

Answer:

All answers apply

Step-by-step explanation:

Although it may seem like it doesnt, the absolute value of -12 is just 12, which ends up still being less than 14.

Absolute value takes away the negative and leaves positive number as a result.

Answer:

all of them since it's absolute value all numbers are below 14

I'm not sure what you mean by 3 or 6a^9, since there are only variables in the photo, but we can try breaking it down.

Let's start with the bottom,

a^2 * a^3 would be a^5 because for exponents you add the exponents of what's multiplied (product rule)

Then using the quotient rule, where you subtract the exponents, a^5/a^5 = a^(5-5)

And anything to the 0th power is 1, so your answer should be 1

Hope that helps!

Answer:

C

Step-by-step explanation:

First of all, we can see for both of the slopes, the Y intercept is both -4, and +4. Now that we know that information, we can go on to "mx" or the slope. now since we've narrowed down the answers, we have C and D left. Now in C, the x for "x+4" doesn't specifically say the value. Now for the equation below x+4 (for C) shows -2x-4, which does show the value of X, which is correct, because it shows in the graph that there's -2x. Now on D, they put the negative symbol on X, which doesn't say the value, but there's no negative in "2x-4" for 2x. and there's no slope that goes through positive 2. Therefore it would be C.

Answer:

The different ways a football team cold score 63 points are by having;

1) 3 touchdowns and 14 field goals

2) 6 touchdowns and 7 field goals

Step-by-step explanation:

The given parameters are;

The worth of each touchdown = 7 point

The worth of each field goal = 3 points

The number of touch down ≥ 1

The number of field goals ≥ 1

Let x represent the number of touchdowns and let y represent the number of field goals, we have;

7·x + 3·y = 63...(1)

x + y ≥ 2...(1)

Making y the subject of the equation, 7·x + 3·y = 63, gives;

3·y = 63 - 7·x

y = 21 - (7/3)·x

Making y the subject of the inequality, x + y ≥ 2, gives;

y ≥ 2 - x

From the attached graph created with Microsoft Excel, we have the points where x ≥ 1, that have a whole number value of y ≥ 0 as follows;

1) When x = 3, y = 14 gives 7×3 + 3×14 = 63

2) When x = 6, y = 7 gives 7×6 + 3×7 = 63

Therefore, the different ways a football team cold score 63 points are;

1) 3 touchdowns and 14 field goals

2) 6 touchdowns and 7 field goals.

Answer:

63 points

1) 3 touchdowns and 14 field goals

2) 6 touchdowns and 7 field goals
