2x=1/4
x= 1/8
because dividing by 2 is the same as multiplying by 1/2

4x=-1/10
x=-1/40
because dividing by 4 is the same thing as multiplying by 1/4

Gemiola [76]

Answer:

See the explanation

Step-by-step explanation:

Given function

$Y=3x+1$

We need to find $y$ value corresponding to each $x$ value.

So, plug each $x$ value in equation we get,

$plug\ x=4\\y=3(4)+1\\y=12+1\\y=13\\\\plug\ x=6\\y=3(6)+1\\y=18+1\\y=19\\\\plug\ x=10\\y=3(10)+1\\y=30+1\\y=31$

Now in next part of question it ask us to check each ordered pair.

Let us plug each $x$ value and $y$ value in the function $y=-3x-5$

$plug\ (1,-8)\\-8=-3(1)-5\\-8=-3-5\\-8=-8\\\\plug(-5,0)\\0=-3(-5)-5\\0=15-5\\0\neq10\\\\plug\ (-2,1)\\1=-3(-2)-5\\1=6-5\\1=1\\\\plug\ (-1,-2)\\-2=-3(-1)-5\\-2=3-5\\-2=-2\\$

we can see ordered pair $(1,8),(-2,1)and(-1,-2)$ true for function $y=-3x-5$

Option D: $y-7=2(x+1)$ is the equation of line in point - slope form

Explanation:

Given that the slope is $m=2$ and the point $(-1,7)$

We need to determine the equation of the line in point - slope form.

The point - slope form can be determined using the formula,

$y-y_1=m(x-x_1)$

Let us substitute the point $(-1,7)$ and the slope $m=2$ in the above formula.

Thus, we have,

$y-7=2(x-(-1))$

Simplifying the terms, we get,

$y-7=2(x+1)$

Thus, the equation of the line in point - slope form is $y-7=2(x+1)$

Therefore, Option D is the correct answer.

What is the range of g(x) = - 2x + 3, if the domain is {-2, - 1,0, 1, 2}?

pshichka [43]

Answer:

{ - 1, 1, 7, 23 }

Step-by-step explanation:

To find the range substitute the values from the domain into g(x)

g(-2) = -2(- 2) + 3 = 4 + 3 = 7

g(- 10) = - 2(- 10) + 3 = 20 + 3 = 23

g(1) = - 2(1) + 3 = - 2 + 3 = 1

g(2) = - 2(2) + 3 = - 4 + 3 = - 1

Range is { - 1, 1, 7, 23 }

In a standard deck of cards there 52 cards of which 26 are black and 26 are red. Additionally, there are 4 suits, hearts, clubs,

stich3 [128]

Using probability concepts, it is found that P(S and D) = 0.1275.

-----------------------

A probability is the <u>number of desired outcomes divided by the number of desired outcomes</u>.
In a standard deck, there are 52 cards.
Of those, 13 are spades, and 13 are diamond.

The probability of selecting a spade with the first card is 13/52. Then, there is a 13/51 probability of selecting a diamond with the second. The same is valid for diamond then space, which means that the probability is multiplied by 2. Thus, the desired probability is:

$P(S \cap D) = 2 \times \frac{13}{52} \times \frac{13}{51} = \frac{2\times 13 \times 13}{52 \times 51} = 0.1275$

Thus, P(S and D) = 0.1275.

6. For what value of p, the binary number 110P/2 represents 25?

lions [1.4K]

Step-by-step explanation:

25 as binary number is

11001

1×2⁴ + 1×2³ + 0×2² + 0×2¹ + 1×2⁰ = 16 + 8 + 1 = 25

25×2 = 50 = 11001 × 2 = 110010

multiplying a binary number by 2 is the save effect as multiplying a normal decimal number by 10 : all digits move one position to the left, and a 0 is put into the empty right position.

and so, we see

110P = 110010

P = 010

FYI : you normally don't mix binary and decimal numbers. if one of the numbers is binary, then all the others have to be binary too.

so, the problem should have looked like

110P/10 = 11001

110P = 11001×10 = 110010

P = 010
