can someone help and explain the answer?

Answer:

x = -4, y = 9

or

(-4, 9)

Step-by-step explanation:

x - 5y = -49

y = -2x + 1

substitute y for -2x + 1

x - 5(-2x + 1) = -49

x + 10x - 5 = - 49

add 5 to both sides

x + 10x - 5 + 5 = - 49 + 5

x + 10x = -44

11x = -44

divide both sides by 11

11x/11 = -44/11

x = -4

substitute x for -4 in any of the original equations

y = -2x + 1

y = -2 * -4 + 1

y = 8 + 1

y = 9

Answer:

x = -4, y = 9 or (-4,9)

Answer:

D 12

Step-by-step explanation:

Answer:

D. 12 cm

Step-by-step explanation:

Because the sum of two sides of a triangle must always be greater than the 3rd side, 12 cannot be the third side because 5+7=12.

Answer:

x=15

Step-by-step explanation:

4x+2x=90 degrees

6x=90

x=15

Answer:

The missing sides are 13 (small) and 2424 (big)

Step-by-step explanation:

The bigger triangle is bigger by 2 so multiply or divide the sides you do know by 2 to find the missing sides.

BC=12

ED= 12*2= 24

FD= 26

AC= 26/2= 13

Answer:

it is true.................

Answer: Your answer is TRUE

Step-by-step explanation:

Answer:

k = 12

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (8, 20)

m = [tex]\frac{20-4}{8-2}[/tex] = [tex]\frac{16}{6}[/tex] = [tex]\frac{8}{3}[/tex]

Repeat using (5, k) as one of the points and equate to [tex]\frac{8}{3}[/tex]

(x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (5, k) , then

m = [tex]\frac{k-4}{5-2}[/tex] = [tex]\frac{k-4}{3}[/tex] = [tex]\frac{8}{3}[/tex] ( cross- multiply )

3(k - 4) = 24 ( divide both sides by 3 )

k - 4 = 8 ( add 4 to both sides )

k = 12

Answer:

1: 9 & -8

2: -4 & -5

3: -10 & 6

4: -8 & 6

5: 3 & 8

Step-by-step explanation:

Given:

The depth, d , of a lake is 57 m, rounded to the nearest integer.

To find:

The error interval for d in the form a ≤ d < b.

Solution:

The depth, d , of a lake is 57 m, rounded to the nearest integer.

If the depths of the lake is 56.5m or greater than this up to 57 m, then the depth, d , of a lake is 57 m, rounded to the nearest integer.

[tex]56.5\leq d\leq 57[/tex]             ...(i)

If the depths of the lake is 57m or greater than this up to 57.5 m but not 57.5 m, then the depth, d , of a lake is 57 m, rounded to the nearest integer.

[tex]57\leq d<57.5[/tex]             ...(ii)

Using (i) and (ii), we get

[tex]56.5\leq d<57.5[/tex]

Therefore, the error interval for d is [tex]56.5\leq d<57.5[/tex].

Answer:

translation

Step-by-step explanation:

Based on the information provided the type of transformation would have been a translation of one or both points. This means that either one or both points were moved. If only one point was moved it would have moved 5 units. If both were moved equally then they would have moved 2.5 units apart. Since we are not told the initial and end values of each point we cannot tell if the translation was a vertical or horizontal translation.

Answer:

The answer is 4

Step-by-step explanation:

1/2+(-5/6)= 1 1/3

1 1/3 + 1/4= 1 7/12

Answer:

A least degree polynomial, having rational coefficients and a leading coefficient of 2, with,-4, 0, 2, and 4 as the zeros of the polynomial is;

f(x) = 2·x⁴ - 4·x³ - 32·x² + 64·x

Step-by-step explanation:

The given parameters of the polynomial are;

The leading coefficient of the polynomial = 2

The zeros of the polynomial = -4, 0, 2, 4

We note that zeros of -4, and 4 gives a factor of the form, (x² - 4²)

For a zero of the polynomial equal to 0, one of the factors of the polynomial is equal to 'x'

To have a leading coefficient of 2, we can add '2' as a factor of the polynomial

Therefore, we can have the factors of the polynomial as follows;

(x² - 4²)·2·x×(x - 2) = 0

From the above equation, using a graphing calculator, we get the following possible polynomial;

(x² - 4²)·2·x×(x - 2) = 2·x⁴ - 4·x³ - 32·x² + 64·x = 0

Therefore, a polynomial, function of least degree that has rational coefficients, a leading coefficient of 2,and the zeros, -4, 0, 2, and 4 is  f(x) = 2·x⁴ - 4·x³ - 32·x² + 64·x.

Answer:

[tex]P(7)=\$208,752[/tex]

Step-by-step explanation:

Exponential Growth

The natural growth of some magnitudes can be modeled by the equation:

[tex]P(t)=P_o(1+r)^t[/tex]

Where P(t) is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.

It's given the annual sales for a surf shop are Po=$130,000. They are increasing at a rate of r=7% = 0.07 per year. Substituting values, the function is:

[tex]P(t)=\$130,000(1+0.07)^t[/tex]

[tex]\boxed{P(t)=\$130,000(1.07)^t}[/tex]

The value of the function after t=7 years is

[tex]P(7)=\$130,000(1.07)^7[/tex]

Computing:

[tex]P(7)=\$130,000*1.6058[/tex]

[tex]\mathbf{P(7)=\$208,752}[/tex]

Answer: same bro

Step-by-step explanation:

Answer:

So basically the hypotenuse will be the side directly opposite from the right angle (the square marked on the triangle), it will always be the longest side

the "opposite" will be the side directly across from the curved angle marked

the "adjacent" will be the side that the curved angle touches, i.e. the one "next to it"

hope this helped!
