Answer:

it all depends on how many squares they actually equal but if they are equal to 1 the slope is -1

Step-by-step explanation:

you will probably be asked later so if you need it the y-intercept it is -2 and the complete equation would be y = -1x - 2

PLS help me Order four and seven tenths repeating, negative four and eight ninths, 490%, and −4.9 from least to greatest.

Digiron [165]

The order from least to greatest negative four and seven tenths repeating, negative four and eight ninths, 490%, and −4.9 from least to greatest is; option A

−4.9,
negative four and eight ninths
four and seven tenths repeating
490%,

<h3>Ascending order</h3>

four and seven tenths repeating

= 4.77777777

negative four and eight ninths

= -4 8/9

= -4.888888888888888

490%

= 490/100

= 4.9

−4.9

Rearranging from least to greatest (ascending order)

-4.9
-4.888888888888888
4.77777777
4.9

Can someone please help me with the answer

pychu [463]

Answer:

$x = \frac{46}{3}$

Step-by-step explanation:

A straight angle is equal to 180° degrees. Since both 9x +4 and 3x -18 is supplementary then I can make this claim below

$(9x + 4 ) + (3x - 8) = 180$

All we have to do now is to solve for x

$(9x + 4) + (3x - 8) = 180 \\ 9x + 4+ 3x - 8 = 180 \\ 12x - 4 = 180 \\ 12x = 184 \\ x = \frac{184}{12} \\ x = \frac{46}{3}$

Factor the expression. 35g^2 – 2gh – 24h^2

stiks02 [169]

Option C: $(7 g-6 h)(5 g+4 h)$ is the correct answer.

Explanation:

The given expression is $35 g^{2}-2 g h-24 h^{2}$

We need to determine the factor of the expression.

Now, let us break the given expression into two groups.

Hence, we get,

$35 g^{2}+28 g h-30 g h-24 h^{2}$

Simplifying, we get,

$\left(35 g^{2}+28 g h\right)+\left(-30 g h-24 h^{2}\right)$

Let us factor out 7g from the term $\left(35 g^{2}+28 g h\right)$

Hence, we have,

$7 g(5 g+4 h)+\left(-30 g h-24 h^{2}\right)$

Similarly, let us factor out -6h from the term $\left(-30 g h-24 h^{2}\right)$

Thus, we have,

$7 g(5 g+4 h)-6 h(5 g+4 h)$

Now, we shall factor out the term $5g+4h$ , we get,

$(7 g-6 h)(5 g+4 h)$

Thus, the factorization of the given expression is $(7 g-6 h)(5 g+4 h)$

Therefore, Option C is the correct answer.
