Answer:

[tex]x=-1+\sqrt{17},\:x=-1-\sqrt{17}[/tex]

Step-by-step explanation:

[tex]x ^ 2 + 2x + 1 = 17[/tex]

[tex]\mathrm{Subtract\:}17\mathrm{\:from\:both\:sides}[/tex]

[tex]x^2+2x+1-17=17-17[/tex]

[tex]\mathrm{Simplify}[/tex]

[tex]x^2+2x-16=0[/tex]

[tex]\mathrm{Solve\;with\;Quadratic\;formula}[/tex]

[tex]x_{1,\:2}=\frac{-2\pm \sqrt{2^2-4\cdot \:1\cdot \left(-16\right)}}{2\cdot \:1}[/tex]

[tex]\sqrt{2^2-4 \cdot1\cdot(-16)} =\sqrt[2]{17}[/tex]

[tex]x_{1,\:2}=\frac{-2\pm \:2\sqrt{17}}{2\cdot \:1}[/tex]

[tex]\mathrm{Separate\:the\:solutions}[/tex]

[tex]x_1=\frac{-2+2\sqrt{17}}{2\cdot \:1},\:x_2=\frac{-2-2\sqrt{17}}{2\cdot \:1}[/tex]

[tex]\mathrm{The\:solutions\:to\:the\:quadratic\:equation\:are:}[/tex]

[tex]x=-1+\sqrt{17},\:x=-1-\sqrt{17}[/tex]

Hence, Answer is [C] [tex]x=-1+\sqrt{17},\:x=-1-\sqrt{17}[/tex]

Answer:C

Step-by-step explanation:

The value of a = 24 and b = 32. Let the original numbers be 3x and 4x since they are in the ratio 3 : 4.

Step 1: Form the new ratios after the given decreases.

The first number decreased by 4 becomes 3x - 4, and the second number decreased by 2 becomes 4x - 2. The new ratio is 2 : 3.

Step 2: Set up the equation based on the new ratios.

We have the following equation based on the new ratios:

(3x - 4) / (4x - 2) = 2 / 3

Step 3: Solve the equation for x.

To solve the equation, we can cross-multiply:

3(3x - 4) = 2(4x - 2)

Expand and simplify:

9x - 12 = 8x - 4

Now, isolate the variable on one side:

9x - 8x = 12 - 4

x = 8

Step 4: Find the values of a and b.

Now that we have the value of x, we can find the values of a and b:

a = 3x = 3 * 8 = 24

b = 4x = 4 * 8 = 32

So, a = 24 and b = 32.

Answer:

Triangle STU is not similar to Triangle VWU

Step-by-step explanation:

For two triangles to be similar, they both should have the same angle measures. To find out if they have the same angle measures, we have to solve for the unknown angles. Remember, a triangle is worth 180°.

Triangle STU:

Triangle VWU:

As you can see, the angles don't have the same angle measures. Thus, they are not similar.

Answer: 400%?

Step-by-step explanation: 2 is 1/4 of 8 which means to get from 2 you need to multiply it by 4, 1=1.00 which is 100% so it is 400%

Step-by-step explanation: If you're asked to solve a quadratic equation by the method of your choice, you should always check to see if the quadratic factors before you try any other method.

In this case, we have a trinomial that

factors as the product of two binomials.

In the first position for each binomial, we will use

our factors of 6x² which are either 6x · x or 3x · 2x.

It's a good idea to try less extreme extreme factors.

That means choose factors a little closer together.

So 3x and 2x would be first on our list.

We do the same for the factors of -35.

Since our constant term is negative, it will factor

as the product of a positive times a negative.

So the factors of -35 are +7 · -5, -5 · +7, -7 · +5, +5 · -7.

Remember to reverse the order of the

factors is your lead coefficient is not 1.

The factors that work in this case are -5 and +7.

So we have (3x - 5)(2x + 7).

To check, take the product of the outer terms and inner terms.

So we have -21x + 10x which is our middle term.

Now set it equal to 0.

So we have (3x - 5)(2x + 7) = 0.

Now use the zero product property.

So either 3x - 5 = 0 or 2x + 7 = 0.

Solving each equation from here, we have x = 5/3 or x = -7/2.

Answer:

k=60

Step-by-step explanation:

k+2k=180

3k=180

k=60

Answer:

k = 60

Step-by-step explanation:

Because supplementary angles are either 2 angles where the sum equals 180, if we take 60 for [tex]\angle {1}[/tex], and then add it to [tex]\angle {2}[/tex], we get 2(60) = 120 for [tex]\angle 2[/tex] and 60 for [tex]\angle 1[/tex], meaning that if we add the values of both angles together, it will be 120 + 60 = 180.

Answer:

1,400 children attend the school

Step-by-step explanation:

If 20% is 280, we can set up a proportion to solve for how many attend the school. I will put the percentages on top and the number of children on the bottom:

-> Please note that a percentage divided by 100 becomes a decimial

[tex]\frac{20}{280}=\frac{100}{x}[/tex]

Cross multiply:

.2 * x = 280 * 1

.2x = 280

Divide both sides of the equation by .2:

1,400 children attend the school

We can check our work by multiplying 1,400 by 0.2:

1,400 * 0.2 = 280 ✓

Using linear function concepts, it is found that:

A linear function is modeled by:

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

In which:

For Company A, the equation is:

y = 1.35y + 100.

The slope is of m = 1.35, hence the unit rate is of $1.35.

For Company B, as already stated in the problem, the unit rate is of $2.05.
