Answer:

<h2>The slope m = -1</h2>

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

(x₁, y₁), (x₂, y₂) - points on a line

We have (-6, 6) and (4, -4).

Substitute:

x₁ = -6, y₁ = 6, x₂ = 4, y₂ = -4

$m=\dfrac{-4-6}{4-(-6)}=\dfrac{-10}{4+6}=\dfrac{-10}{10}=-1$

4x-11y=68 ; 6x+5y=-27 by elimination

zimovet [89]

Answer:

$x=\frac{1}{2}\\\\y=-6$

Step-by-step explanation:

Given the following system of equations:

$\left \{ {{4x-11y=68} \atop {6x+5y=-27}} \right.$

In order to solve the system of equations using the Elimination Method, you can follow these steps:

- Multiply the first equation by -6 and the secondd equation by 4.

- Add both equations.

- Solve for "y".

Then:

$\left \{ {{-24x+66y=-408} \atop {24x+20y=-108}} \right\\.........................\\86y=300\\\\y=\frac{-516}{86}\\\\y=-6$

- Substitute the value of "y" into one of the original equations and solve for "x":

$6x+5(-6)=-27\\\\6x=-27+30\\\\x=\frac{3}{6}\\\\x=\frac{1}{2}$

0. Juan has been saving for a new bike for two months. So far, he has saved

antiseptic1488 [7]

<u>Given</u>:

Juan has been saving for a new bike for two months. So far, he has saved $150 for the bike.

The money that he has saved so far is 30% of the cost of the bike.

We need to determine the total cost of the bike.

<u>Total cost of the bike:</u>

Let x denote the total cost of the bike.

The total cost of the bike is given by

$30\% \ of \ x=150$

The value of 30% can be written as $\frac{30}{100}$

Thus, we get;

$\frac{30}{100} \times x=150$

Multiplying both sides by $\frac{100}{30}$ , we have;

$x=150 \times \frac{100}{30}$

Simplifying, we have;

$x=\frac{15000}{30}$

$x=500$

Thus, the value of x is 500.

Hence, the total cost of the bike is $500.

HELPPP!!! And explain please.

Answer:

After correcting error of Mia and solving the expression $0.38 \times 3 \div(-1/20)\times5\div(-8)$ we get 14.25

Step-by-step explanation:

The given expression is: $0.38 \times 3 \div(-1/20)\times5\div(-8)$

First I solve the expression, and then will point the error

$0.38 \times 3 \div(-1/20)\times5\div(-8)\\Converting \ \div \ sign \ into \ \times the \ term \ is \ inverted\\=0.38 \times 3 \times(-20)\times5\times(-1/8)\\=0.38\times 3 \times-20\times5\times-1/8\\=1.14 \times-20\times5\times-1/8\\=-22.8\times5\times-1/8\\=-114\times-1/8\\=\frac{-114}{-8}\\=14.25$
