What is the solution of the following system
8x + 14y = 4
-6x - 7y = -10

a) (4,-4)
b (4,-2)
c (2,5)
d (6,-4)

Answers

Answer 1

Step-by-step explanation:

8x + 14y = 4 ...1

-6x - 7y = -10 ...2

...2 × 2 in 2 sides of the equation

-12x -14y = -20 ...3

...1 + ...3

8x + 14y +(-12x -14y) = 4 +(-20)

8x + 14y - 12x -14y = 4 - 20

-4x = -16

x = (-16)/(-4)

= 4

replace x in ...1 or ...2 you will reserve y value

and answer in the term of (x,y)

Write the equation of the line fully simplified slope-intercept form.

Answers

Answer:

The equation of the line in slope-intercept form is y = -x + 6

Step-by-step explanation:

The form of the slope-intercept form of the linear equation is

y = m x + b, where

m is the slope of the lineb is the y-intercept

The rule of the slope is [tex]m=\frac{y2-y1}{x2-x1}[/tex] , where

(x1, y1) and (x2, y2) are two points on the line

Let us choose two points on the line to form the equation

∵ Points (6, 0) and (0, 6) lie on the line

∴ x1 = 6 and y1 = 0

∴ x2 = 0 and y2 = 6

→ Substitute them in the rule of the slope to find it

∵ [tex]m=\frac{6-0}{0-6}=\frac{6}{-6}=-1[/tex]

m = -1

→ Substitute it in the form of the equation above

∵ y = -1(x) + b

y = -x + b

∵ b is the y-intercept

∵ The y-intercept is the value of y at x = 0

∵ At x = 0, y = 6

b = 6

→ Substitute the value of b in the equation

∵ y = -x + 6

The equation of the line in slope-intercept form is y = -x + 6

Josh practices free throws during basketball practice on Monday and Tuesday, On Monday, he attempts 15 free throws and 6 basketballs
went in the basket. Over both days, Josh wants at least 80% of his balls to go in the basket. If he makes every free throw on Tuesday,
what is the minimum number of free throws required on Tuesday to reach his goal?

Answers

Answer:

30

Step-by-step explanation:

For the minimum free throws, he must put every throw to the basket.

So, let n be the number of throws for Tuesday, in which all the throws are successful.

So, over both the days, total free throws he makes= 15+n.

Total numbers of throws that went in the basket= 6+n.

As he wants at least 80% of his balls to go in the basket.

So, 6+n is greater than or equal to 809% of 15+n, i.e

[tex]6+n\geq \frac{80}{100}\times (15+n)[/tex]

[tex]\Rightarrow 30+5n\geq 60+4n[/tex]

[tex]\Rightarrow n\geq 30.[/tex]

Hence, the minimum number of free throws required on Tuesday to reach his goal is 30.

The students at Norton School were asked to name their favorite type of pet. Of the 430ilar results, about students surveyed, 258 said that their favorite type of pet was a dog. Suppose that only 100 students were surveyed, with similar results about how many students would say that a dog is their favorite types of pet?

Answers

Answer: 60

Step-by-step explanation:

From the question, we are informed that 430 students were surveyed and 258 said that their favorite type of pet was a dog. The fraction/decimal of those that chose dog as their favorite pet will be:

= 258/430

= 3/5

= 0.6

Suppose that only 100 students were surveyed, the number of students that would say that a dog is their favorite types of pet will be:

= 0.6 × 100

= 60

i know she graphed it correctly but i don't know the steps she took to graph it

Answers

She graphed it correctly.

The inequality [tex]3y \le 2x[/tex] is the same as [tex]y \le \frac{2}{3}x[/tex] after dividing both sides by 3 to isolate y.

From here you graph [tex]y = \frac{2}{3}x[/tex] which is a straight line through (0,0) and (3,2). This line is made solid because of the "or equal to" as part of the inequality sign above.

We shade below the solid boundary due to the "less than" portion of the inequality sign.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.

Suppose the number is x,

700% of x is 154

Apply the multiplication arithmetic operation.

(700/100) × x =154

7x=154

Divide 7 from both sides in the equation,

x=154/7

x=22

Thus, the obtained number will be 22. As a result, 700% of x is 154.

Explain why the slope of line is 26.

Answers

Answer:

Your question is lacking some details.

However, slope is determined by rise over run. You can get the rise by subtracting the change in y-values (coordinates) and the rise by subtracting the change in x-values (coordinates) .

Having 26 as slope means that the slope has gone up 26 units in the coordinate plane then 1 unit to the right.

Elizabeth won a $300 gift certificate at silver gym. A membership costs $15 a month and has a one- time fee of $50. Complete the equation that models the number of months,x, her gift certificate is will pay for a Silver gym.

Answers

The correct answer is 15 x + 50 = 300

Explanation:

In an equation, the different values show a specific mathematical relationship, and the equality represented by the symbol (=) is used to find an unknown value. In the case presented, the unknown value is the number of months Elizabeth can pay using her $300 gift certificate. This means the letter x in the equation represents the number of months.

Moreover, this x should be multiplied by the month membership or $15 considering Elizabeth will need to pay this fee each month and this should be added to the one-time fee of $50. This implies the first part of the equation is 15x + 50. Finally, this value should be equal to the total money in the certificate or 300. According to this, the equation is 15x + 50 = 300.
