Answer:

The values are a=6, b=8

Step-by-step explanation:

System of Equations

We are given the system of equations:

ax - by = 4

bx - ay = 10

And it's known the solutions are: x=2, y=1.

Plugging in the solutions:

2a - b = 4      [1]

2b - a = 10      [2]

Now we have to solve the system above. Multiply [1] by 2:

4a - 2b = 8

Now we add with [2]:

3a = 18

a = 18/3 = 6

a = 6

From [2]:

2b - 6 = 10

2b = 16

b = 16/2 = 8

b = 8

The values are a=6, b=8

Answer:

To find the GCF, do the prime factorization of both numbers.

42 = 2 x 3 x 7

28 = 2 x 2 x 7

The GCF uses the numbers that appear in BOTH, 2 x 7 = 14 is the GCF of the numbers.  There is no variable GCF because there isn't a variable that appears in both.

Taking out the GCF gives you:

14(3x + 2y)

Step-by-step explanation:

Answer:

14(3x + 2y)

Find the GCF.

It is 14.

Use the distributive property.

Then, multiply each term.

Answer:

a. 8.5

b. 10

Step-by-step explanation:

a.) 1, 1, 2, 7, 7, 10, 12, 16, 20, 34

Since 7 and 10 are tied in the middle, then we need to find a number in the   middle of the two.

8.5 is in the middle of 7 and 10, therefore 8.5 is the mean.

b.) We need to do the same thing we did before, except add 22 to it's directed place:

1, 1, 2, 7, 7, 10, 12, 16, 20, 22, 34

Since 10 is in the middle, 10 is the new mean.

Hope this helps! :D

Ignore the negative sign, since that only affects the sign of the final product

3415₇ × 432₇

You can compute the product by considering the digit expansion, by which I mean first expanding each number as sums of powers of 7:

3415₇ = 3000₇ + 400₇ + 10₇ + 5₇

(It's the same thing as writing, for example, the decimal 3415 as 3000 + 400 + 10 + 5, just in a different base.)

Similarly,

432₇ = 400₇ + 30₇ + 2₇

Then apply the distributive property:

= (3000₇ + 400₇ + 10₇ + 5₇) × (400₇ + 30₇ + 2₇)

= 3000₇ × (400₇ + 30₇ + 2₇)

… + 400₇ × (400₇ + 30₇ + 2₇)

… + 10₇ × (400₇ + 30₇ + 2₇)

… + 5₇ × (400₇ + 30₇ + 2₇)

= {12}00000₇ + {9}0000₇ + 6000₇

… + {16}0000₇ + {12}000₇ + {8}00₇

… + 4000₇ + 300₇ + 20₇

… + {20}00₇ + {15}0₇ + {10}₇

where I use the curly braces to indicate products (written in base 10) of digits that exceed 6. Anything in these braces needs to be properly converted to base 7. For example,

{12}₇ = 7 + 5 = 15₇

So you would have

= 1500000₇ + 120000₇ + 6000₇

… + 220000₇ + 15000₇ + 1100₇

… + 4000₇ + 300₇ + 20₇

… + 2600₇ + 210₇ + 13₇

Add everything up:

• In the 7⁰ place,

3₇

• In the 7¹ place,

1₇ + 1₇ + 2₇ = 4₇

• In the 7² place,

2₇ + 6₇ + 3₇ + 1₇ = {12}₇ = 15₇

• Carry the 1 (underlined). In the 7³ place,

2₇ + 4₇ + 1₇ + 5₇ + 6₇ + 1₇ = {19}₇ = 25₇

• Carry the 2. In the 7⁴ place,

1₇ + 2₇ + 2₇ + 2₇ = {7}₇ = 10₇

• Carry the 1. In the 7⁵ place,

2₇ + 1₇ + 5₇ + 1₇ = {9}₇ = 12₇

• Carry the 1. In the 7⁶ place,

1₇ + 1₇ = 2₇

So, we end up with

3415₇ × 432₇ = 22045543₇

and thus

3415₇ × (-432₇) = -22045543₇

Answer:

23 ft

Step-by-step explanation:

The computation of the maximum length of the base of the triangle is as follows:

Area of triangle is = 4 × 6 ÷ 2

= 12 ft²

Now the maximum area of the rectangle is

= 150 - 12

= 138 ft²

L = ?

W = 6 ft

Area of rectangle is  = L × W

L × 6 = 138

L = 138 ÷ 6

= 23 ft

Answer:

math way

Step-by-step explanation:

Answer:

8. Not similar

9. Similar

Step-by-step explanation:

8. You could try to us the AA theorem which means that two angles in the triangle are equal, which would mean that the triangles are similar. But 46+58=104 and 180-104=76 so there are not two similar angled between the triangles.

9. You can use the same theorem for this problem (AA). So 106+31=137 and then 180-137=43 which is one of the angles in the second triangle. Since at least two of the angles are equal, you can use AA theorem yo prove they are similar.

Hope this helps!

Answer:

The two triangles in 8 are not similar. The two triangles in 9 are similar.

Step-by-step explanation:

The three angles of all triangles must add up to 180°.

The left triangle in 8 has these angles:

46  58  and (180 - (46+58)) = 76

The right triangle in 8 has these angles:

58  78  and (180 - (58+78)) = 44

So, 46 | 44 and 76 | 78 are dissimilar.

The left triangle in 9 has these angles:

106  31  and (180 - (106+31)) = 43

The right triangle in 9 has these angles:

31  43  and (180 - (31+43)) = 106

But the triangles in 9 all have the same angles: 31  |  43  |  106.

Answer:

Store A

Step-by-step explanation:

Store A

50/100=0.5

0.5×5=2.5

The watch will be 50-2.5=47.5

Store B

60/100=0.6

0.6×20=12

The watch will be 60-12=48

So the watch price in store A is better

Answer:

You should buy from Store A because you're paying $0.50 less than if you were to buy from Store B.

Step-by-step explanation:

First, don't subtract if it's a percentage. You will want to multiply to get the amount you're removing from the original price.

Let's look at Store A. $50 and 5% discount. 50 * 0.05 = 2.5. Remove 2.5 from 50.

50 - 2.5 = 47.5

When you buy from Store A, you will pay $47.5

Let's look at Store B. $60 and 20% discount. 60 * 0.20 = 12. Remove 12 from 60.

60 - 12 = 48

When you buy from Store B, you will pay $48

Ultimately, Store A is the best option because you're paying less.

Answer:

The equation shows the temperature over time will be:

Hence, option (C) is correct.

Step-by-step explanation:

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

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

where m is the rate of change or slope and b is the y-intercept

Given that one very cold morning, it was -7°F.

Thus, the y-intercept = b = -7

Given that as the day went on, the temperature rose 3 degrees each hour.

Thus, the rate of change = slope = m = 3

Thus, substituting m = 3 and b = -7 in the equation

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

[tex]y = 3x + (-7)[/tex]

[tex]y = 3x - 7[/tex]

Therefore, the equation shows the temperature over time will be:

Hence, option (C) is correct.

Answer:

Option A

Step-by-step explanation:

From the graph attached,

Vertical asymptote of the given function → x = -4

Horizontal asymptote → y = 0

Oblique asymptote → None

Therefore, graph that has been given in the picture is,

F(x) = [tex]\frac{1}{(x+4)^2}[/tex]

Option (A) will be the answer.
