Which inequality is equivalent to 8x - 6y < 10?

1 answer:

7 0

If you would like to know which inequality is equivalent to 8 * x - 6 * y < 10, you can calculate this using the following steps:

8 * x - 6 * y < 10 /2
4 * x - 3 * y < 5
or you can also put this into another form:
4 * x - 5 < 3 * y /3
y > 4/3 * x - 5/3

Answer:

$14\sqrt{3}-8\sqrt{5}$

Step-by-step explanation:

we have

$2\sqrt{20}-4\sqrt{45}+7\sqrt{12}$

we know that

$2\sqrt{20}=2\sqrt{2^{2}5} =2(2)\sqrt{5}=4\sqrt{5}$

$4\sqrt{45}=4\sqrt{3^{2}5} =4(3)\sqrt{5}=12\sqrt{5}$

$7\sqrt{12}=7\sqrt{2^{2}3} =7(2)\sqrt{3}=14\sqrt{3}$

substitute the values in the expression above

$4\sqrt{5}-12\sqrt{5}+14\sqrt{3}$

Combine like terms

$14\sqrt{3}-8\sqrt{5}$

PLZ HELP!<br> find the value of f(-2) for the function f(x)=4x+10<br> Show work please

natita [175]

Answer:

f(-2) = +2

Step-by-step explanation:

Let x = -2

So,

f(x) = 4x + 10

Substituting the value of x gives ,

f(-2) = 4 × (-2) + 10 = 10 - 8 = 2

Sal and Jen went to the store together, and each bought the same car stereo.

scZoUnD [109]

Answer: Sal used a debit card and paid a total of $324.80 for the stereo. (I took the test too)

Step-by-step explanation: Multiply $21.30 by 18 months. Then subtract the interest, $58.60, from the product because Sal paid immediately with a card which implies using a debit card. You get $324.80.

Step-by-step explanation:

you can simplify it by turning a²+b²/a-b

into

(a-b)²+2ab / a-b

eliminate the fraction

a-b +2ab

a=-1

b=-5

-1-(-5)+2*-1*-5

Can someone answer question 10-11-12 for me.

tresset_1 [31]

Width of the rectangle is 12 cm.

Solution:

The length of a rectangle is 4 cm more than its width , and the area of the rectangle is 96 cm². Find the width of the rectangle.

Given data:

Let x be width of the rectangle.

Length of the rectangle = (x + 4) cm

Area of the rectangle = 96 cm²

length × breadth = 96

$(x+4)\times x =96$

$x^2+4x=96$

Subtract 96 from both sides.

$x^2+4x-96=0$

Let us factor the polynomial.

$x^2+8x-12x-96=0$

Take x common in 1st two terms and -12 common in next two terms.

$x(x+8)-12(x+8)=0$

Now, take (x + 8) common in both terms.

$(x+8)(x-12)=0$

x + 8 = 0 and x - 12 = 0

x = -8 and x = 12

Dimension cannot be in negative terms, so ignore x = -8.

Width = 12 cm

Width of the rectangle is 12 cm.
