Answer:

x = 0, y = 3

Step-by-step explanation:

When using graphing to solve a system of equations, the intersection point is the solution. Most points on a graph follow a certain way of writing them and it looks like this: (x, y).

Here, the coordinates of the intersection point is: (0, 3). Thus the solution would be:

(x, y)

(0, 3)

x = 0, y = 3

Answer:

3

Step-by-step explanation:

Answer:

(0, 0) is the solution of the inequality y - 9 > 3x - 10.

Step-by-step explanation:

Given the solution point

Let us substitute the point (0, 0) in the inequality to determine which inequality satisfies the equation or not.

CHECKING FOR

y - 9 > 3x + 10

substiture (0, 0) i.e. x = 0, y = 0 in the inequality

0 - 9 > 3(0) + 10

-9 > 10

FALSE

CHECKING FOR

y - 9 > 3x - 10

substiture (0, 0) i.e. x = 0, y = 0 in the inequality

0 - 9 > 3(0) - 10

-9 > 10

True

CHECKING FOR

y + 9 > 3x + 10

substiture (0, 0) i.e. x = 0, y = 0 in the inequality

0 + 9 > 3(0) + 10

9 > 10

FALSE

Therefore, we conclude that only the second inequality i.e. y - 9 > 3x - 10 satisfies the inequality.

Hence, (0, 0) is the solution of the inequality y - 9 > 3x - 10.

Answer:

The equation is:

[tex]x=\frac{Total\:Expenses+Profit}{Cost\:of\:1\:shirt}[/tex]

Solving we get: Laura sold 19 shirts in the festival.

Step-by-step explanation:

Cost of 1 shirt = $6

Total expenses = $30

Profit made = $84.

We need to write equations that helps in finding the number of t-shirts Laura sold.

Let x= represents number of t-shirts

Since profit was $84, and expense was $30

So, Total money earned = Total expense + Profit

Now, 1 shirt cost 6 dollars, so if we divide Total Money earned by 6 we can find x (the number of shirts sold)

Writing equation:

[tex]\mathbf{x=\frac{Total\:Expenses+Profit}{Cost\:of\:1\:shirt}}[/tex]

Putting values we can find x

[tex]x=\frac{30+84}{6}\\x=\frac{114}{6}\\x= 19[/tex]

So, Laura sold 19 shirts in the festival.

Answer: 9

Step-by-step explanation:

27 ^ 2/3 is equal to [tex](\sqrt[3]{27})^2[/tex]

3 * 3 * 3 = 27

so, [tex]\sqrt[3]{27}[/tex] = 3

3 * 3 = 9

so, [tex]3^{2}[/tex] = 9

Answer:

The second one is correct as 108 is double 54

Step-by-step explanation:

Therefore since 54 licks gets one lollipop gone 108 would get 2 lollipops gone

Answer:

m=undefined; 12/0

Step-by-step explanation:

The classmate's mistake is that she should have placed the y and top and the x on the bottom.

m= 10+2/8-8

m= 12/0

The slope is undefined, meaning that it is a vertical line.

Answer:

5 and -8

Step-by-step explanation:

One number must be negative since the product of the 2 number is negative (5 x -8 = -40). They both cannot be negative, if they were the product would then be positive. The negative number must have a absolute value that is larger than the positive, the negative numbers distance from 0 must be larger than the positive, -8 has a distance of 8 and 5 has a distance of 5. The sum of the two numbers is

=5 + (-8)

=5 - 8  

= -3

Answer:

kool-aid - $1.74

Sugar - $7.84

Total =$9.58

Step-by-step explanation:

kool-aid = $ 0.29 × 6 = 1.74

×6 because she bought 6 packages of Kool-aid and the price of each was $0.29

sugar = $3.92×2 = 7.84

×2 because she bought 2 packages of sugar and price for each was $3.92

total = $9.58

Add $1.74 + $7.84

Answer: Subtract 3.1 from 12.9

Step-by-step explanation:

The first step in evaluating the expression (12.9 – 3.1) × 6.2 – 2 + 43 is to open the bracket first and then subtract 3.1 from 12.9 which will give 9.8.

This follows the rule of BODMAS which says that B which stands for Bracket must be opened and solved first in a given expression.

Complete question :

Answer:

Width = 14 yards ; length = 25 yards

Step-by-step explanation:

Given that :

The length of a rectangular garden is 3 yd less than twice its length. The perimeter of the garden is 78 yd. What are the width and length of the garden?

Width of garden (W) = w

Lenght of garden (L) = 2w - 3

Perimeter of a rectangle : 2 (L + W)

2(2w - 3 + w) = 78

2(3w - 3) = 78

6w - 6 = 78

6w = 78 + 6

6w = 84

w = 14 yards

Length = 2(14) - 3

Length = 28 - 3 = 25 yards

Answer:

3.) a. 9mm b. 10mm c. 8mm

Step-by-step explanation:

All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.

Formula:

a + b = (answer) > c

a + c = (answer) > b

b + c = (answer) > a

try to solve it yourself so you can do it on your own in the future.

Answer:

-5

Step-by-step explanation

Given the function  f(x)=-4x^2+2x-5, the y intercept occurs at x = 0

Substitute x = 0 into the function and find y as shown;

f(x)=-4x^2+2x-5

f(0)=-(0)^2+2(0)-5

f(0)=0-5

f(0) = -5

The coordinate point is (0, -5)

Hence the value of the y coordinated is -5
