Answer:

x = 4y + 6

Step-by-step explanation:

x-4y=6

2x-8y=12

multiply 2 on both side in equation 1, and multiple - on both side in equation 2:

2x-4x=12

-2x+8y=-12

so the equation becomes:

4y=0

y=0

put the value of y in both of the equations:

x=6 equation 1

x=6 equation 2

so,

x = x

then,

x = 4y + 6 equation 1

-2 ( x - 4y ) = -12

x - 4y = -12/ -2

x - 4y = 6

x = 4y + 6

so the ans is:

x = 4y +6

Hello!

[tex]\large\boxed{x = -2}[/tex]

3(x + 4) = 6

Distribute the terms inside of the parenthesis with the coefficient outside:

3(x) + 3(4) = 6

Simplify:

3x + 12 = 6

Subtract 12 from both sides:

3x + 12 - 12 = 6 - 12

3x = -6

Divide both sides by 3:

3x/3 = -6/3

x = -2

The relative frequency for males in the age group 60-69 is 1/2. So, option A is the correct one.

Given that,

Total number of residents in the retirement home who are in the age group 60-69 = 10 + 10 = 20

Number of males who are in the age group 60-69 = 10

The formula to find the relative frequency is,

Relative frequency = Number of counts in the subgroup / Total counts

Substituting,

Relative frequency = 10/20 = 1/2

Answer:

(a) 83% of the scores were at or below her score.

(b) 17% was above her score.

Step-by-step explanation:

Given that:

Percentile score of Angela in the general aptitude test = 83rd percentile

To find:

a) Percentage of scores which were at or below her score?

b) Percentage of score which were above her score?

Solution:

First of all, let us learn about the term "Percentile"

Percentile is the value below which the certain percent of people/marks fall.

Therefore, when we say percentile of someone's score is [tex]x[/tex], then there are [tex]x\%[/tex] of scores are at the same level or below.

And [tex](100-x)\%[/tex] of the scores are above this level.

Therefore, we can say that:

83% of the scores were at the same level or below the score of Angela.

And [tex](100-83)\% = 17\%[/tex] of the scores were above the score of Angela.

B. y= -4x + 28

Step-by-step explanation:

To find the equation of this line first put it into slope-point form, [tex]y-y_{1} =m(x-x_{1})[/tex] where [tex]y_{1}[/tex] and [tex]x_{1}[/tex] are the y and x coordinates and m is the slope. So plug in the information to get the equation, y-8=-4(x-5). Then solve for y,

First, distribute the -4

y-8=-4x+20

Next, add 8 to both sides

y=-4x+28

Answer:

0.14secs

Step-by-step explanation:

Given the equation that models the height expressed as;

h(t)=-4.9t^2-v_0 t+h_0

Given v0 = 12m/s

h0 = 1.8m

The equation becomes

h(t)=-4.9t^2-12t+1.8

The height of the ball on the ground level is zero

Substituting into the equation

0 = -4.9t^2-12t+1.8

Multiply through by -10

49t²+120t-18 = 0

Factorize and get t:

t = -120±√120²-4(49)(-18)/2(49)

t = -120±√14400+ 3528/98

t = -120±√17928/98

t = -120±133.89/98

t = 13.89/98

t = 0.14secs

Hence it takes 0.14secs until it reaches the ground

Answer: Part A An equivalent expression of 4(a + 12) + 5(8) is 4a + 4(12) + 5(8)

or 4a + 48 + 40

Part B:  using 15 in place of a,  the Rodriguez family spent $148 on tickets.

Step-by-step explanation: We can use the distributive property to create equivalent expressions.

Part B:  Substitute 15 in place of a and do the calculations

4(15 + 12) + 5(8)

60 + 48 + 40

The time taken to grow to $8000 is 17 years and 4 months.

The formula used to find the time compounded continuously.

t = ln(A/P) / r

It is the interest we earned on the interest.

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + r/n)^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

We have,

P = $4000

A = $8000

r = 4%

The formula used:

t = ln(A/P) / r

t = ln(8,000/4,000) / 0.04

t = 17.329 years

This means,

= 17 years 4 months

Thus,

The time taken to grow to $8000 is 17 years 4 months.

Answer:

The gradient of the straight line that passes through (2, 6) and (6, 12) is [tex]m = \frac{3}{2}[/tex].

Step-by-step explanation:

Mathematically speaking, lines are represented by following first-order polynomials of the form:

[tex]y = b + m\cdot x[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]m[/tex] - Slope.

[tex]b[/tex] - Intercept.

The gradient of the function is represented by the first derivative of the function:

[tex]y' = m[/tex]

Then, we conclude that the gradient of the staight line is the slope. According to Euclidean Geometry, a line can be form after knowing the locations of two distinct points on plane. By definition of secant line, we calculate the slope:

[tex]m = \frac{y_{B}-y_{A}}{x_{B}-x_{A}}[/tex] (2)

Where:

[tex]x_{A}[/tex], [tex]y_{A}[/tex] - Coordinates of point A.

[tex]x_{B}[/tex], [tex]y_{B}[/tex] - Coordinates of point B.

If we know that [tex]A(x,y) = (2,6)[/tex] and [tex]B(x,y) = (6,12)[/tex], then the gradient of the straight line is:

[tex]m = \frac{12-6}{6-2}[/tex]

[tex]m = \frac{6}{4}[/tex]

[tex]m = \frac{3}{2}[/tex]

The gradient of the straight line that passes through (2, 6) and (6, 12) is [tex]m = \frac{3}{2}[/tex].

D. y <-x - 3

Step-by-step explanation:

-3x + 2y > 5y + 9

Subtract 2y from 5y on the other side

5y - 2y = 3y

-3x > 3y + 9

Add 3x and put it the other side

0 > 3x + 3y + 9

Subtract 3y and put it on the other side

0 - 3y = -3y

-3y > 3x + 9

Divide by -3 on both sides

-3y/-3 > 3x + 9/-3

-3y/-3 = y

3x + 9/-3 = -x - 3

y > -x - 3

MOST IMPORTANT STEP OF ALL: Switch the inequality sign around because you divided with a negative number which is -3. That's a rule in inequality.

y < -x - 3

So your final answer is y < -x - 3

Answer:

C. [tex] \frac{h}{j} = \frac{k}{i} [/tex]

Step-by-step explanation:

Given that [tex] \overline{TU} [/tex] is parallel to [tex] \overline{QR} [/tex], therefore:

[tex] \frac{ST}{TQ} = \frac{SU}{UR} [/tex]

ST = h

TQ = j

SU = k

UR = i

Therefore substituting these into the equation, we have:
