Select the point that satisfies

Vika [28.1K]

Answer:

A. (5,5)

Step-by-step explanation:

Plug in (5,5) for the x and y values according to the ordered pair. In this case the equation should turn out like this :5 ≤ 5²- 4(5) + 2

Simplify the equation : 5 ≤ 25 - 20 + 2
5 ≤ 7
A is the answer because it satisfies the inequality as 5 is less than or equal to seven. Though, in this case it is just less than, but not equal to.

if the area of a right isosceles triangle is 128 sq . m, what will be length of the identical side of the triangle

kolezko [41]

Let's see. What is a right isosceles triangle?

A right isosceles triangle is a triangle with one right angle with at least two equal sides. In this case, it would have to be ONLY two because it has a right triangle.

What is the formula for the area of an isosceles triangle?

When y = the identical side lengths of the triangle,

and A = area,

(y × y) ÷ 2 = A

Note: Remember to compute from left to right! :)

We divide by two because when you multiple the two identical sides, you would get a square. However, we're trying to find the right isosceles triangle, and we divide by two.

Now, we can plug-in our values!

(y × y) ÷ 2 = 128

(y × y) = 64

Now, we square root both sides!

y = √64

y = 8

The length of the identical sides of the triangle is 8 meters.

A store sells televisions for $360 and DVD burners for $270. The entire stock is worth $52,920 and there are a total of 164 tele

bogdanovich [222]

Answer: 96 Televisions, 68 DVD burners

Step-by-step explanation:

Let T represent the quantity of televisions

Let D represent the quantity of DVD burners

Given:

value of television (T) = 360

value of DVD burners (D) = 270

Total value = 52,920

Equations:

Value: 360T + 270D = 52,920

Quantity: T + D = 164

We can solve the system of equations using the Elimination Method:

-1(360T + 270D = 52,920) → -360T - 270D = -52,920

360(T + D = 164) → 360T + 360D = 59,040

90D = 6,120

÷90 ÷90

D = 68

Input the value of D into one of the equations to solve for T

T + D = 164

T + 68 = 164

T = 96

You are knitting a blanket. You want the area of the planet to be 24ft^2. You want the length of the blanket to be 2ft longer th

frosja888 [35]

The area of the blanket - 24 ft²
length being longer than the width means that blanket is a rectangle
width of the blanket = x
length of blanket = x +2
area = length * width
area = x * (x+2)
= x² + 2x
since area = 24
x² + 2x = 24
x² + 2x - 24 = 0
we have a quadratic equation and we need to now solve for x
x² + 6x - 4x - 24 = 0
x (x + 6) - 4(x + 6) = 0
(x-4) (x+6) = 0
x-4 = 0 or x + 6 = 0
x = 4 or x = -6
x could be either 4 or -6. since dimensions cannot have negative values,
x ≠ -6
therefore x = 4
width = 4 ft
length = 6 ft
