Can someone please help me with this question

Answer:

you substitute x for 4

Step-by-step explanation:

so its f(x) and f(4) so you use 4 for x so you would solve f(x)=3(4)+2

Answer:

  1. 2x +2y = 310; x -y = 55

  2. y = 50, x = 105

Step-by-step explanation:

Let the numbers be represented by x and y. Double the numbers would give 2x and 2y. We're told the sum of the doubled numbers is 310, so one equation is ...

  2x + 2y = 310

The difference of the numbers is (x-y). We're told that difference is 55, so the other equation is ...

  x - y = 55

__

We can divide the first equation by 2, and subtract the second.

  1/2(2x +2y) -(x -y) = 1/2(310) -(55)

  2y = 100 . . . . . . . simplify

  y = 50 . . . . . . . . . divide by 2

  x -50 = 55   ⇒   x = 105 . . . . use the second equation to find x

The two numbers are 105 and 55.

Answer: C. [tex]4(\dfrac13g-3)[/tex]

Step-by-step explanation:

Given: Robin braided g inches of a friendship bracelet.

Number of inches braided by Olivia = [tex]\dfrac13g-12[/tex]

The total number of inches braided by Robin and Olivia = Number of inches braided by  Robin + Number of inches braided by Olivia

[tex]=g+\dfrac13g-12\\\\=\dfrac43g-12\\\\\=4(\dfrac13g-3)[/tex]

The total number of inches braided by Robin and Olivia = [tex]4(\dfrac13g-3)[/tex]

Hence, C. is the correct option.

Answer:

The paper is right.

Step-by-step explanation:

The fraction is [tex]\frac{4}{5}[/tex] multiplied by [tex]\frac{3}{3}[/tex] and the answer is [tex]\frac{12}{15}[/tex]. How did it do that? Well, the numerator (top number),4, was multiplied by the other numerator ,3, which is 12. The same thing with the denominator (bottom number), the denominator,5, was multiplied by the other denominator ,3, which is 15. But as seen in the paper, the fraction

Answer:

Now how did I find the translation rule ( x - 1, y + 4). Well basically, I did was

8 - 9 = -1

-4 - (-8) = 4

Now if you use the same translation rule for (9, -8), you will get :-

(x - 1, y + 4)

( 9 - 1, -8 + 4)

( 8, -4)

I get the same answer that is given in the problem.

Hope this helps, thank you !!

Answer:

200

Step-by-step explanation:

so the expression is what is 66 is 13% of what number ( i think)

first turn the percent into a decimal by divided it by 100

33/100 = 0.33

because we are trying to find the whole we divide the given part by the decimal so,

66/0.33 =200, so

66 is 13% of 200

25 if im not wrong......

Răspuns:

292,50

Explicație pas cu pas:

Dobânda totală% = (1% + 16%) = 17% = 17/100 = 0,17

Suma principală depusă, P = 250

Suma totală, A după 1 an poate fi calculată astfel:

A = P (1 + rt)

Unde ; r = rata dobânzii; t = timp

A = 250 (1 + (0,17 * 1))

A = 250 (1,17)

A = 292,5

Answer:

126 :)

Step-by-step explanation:

Answer:

Step-by-step explanation:

first find angle ∠U,

As sum of angle in triangle = 180°

Now ∠U+∠V+∠W=180°

88°+38°+∠U=180°

∠U=54°

Now total horizontal line = 180°

∠NUV=180°-54°=126°

The slope is 1/4 and 2 is the y intercept

Answer:

it's b

Step-by-step explanation:

the reason it's b is because conduction happens when something hot comes in contact with something cold which heats the cold thing up and cooling the hot thing eventually they will both be room temperature

Answer:

5/8

Step-by-step explanation:

8/8-3/8=5/8

Answer:

The answer is C

Step-by-step explanation:

I got this by these steps:

1. Since you have the transversal FH you know that H is going to equal 180

2. So all you do know is subtract 180-82

3. You get 98

4. M<FHJ is 98

Hope that helps

Answer:

=28

Step-by-step explanation:

since its made of two triangles, you can calculate one of the triangles and multiply by two

the degrees of a triangle is 180 degrees

70+82= 152

180-152= 28

Step-by-step explanation:

There is no possible answer to this equation but this is the most accurate equation, since you cant go any further, this is your simplified form.

Answer:

you need to post a picture of the options, but the answer is add seven to both sides.

Step-by-step explanation:

Answer:

add 7 to 5

Step-by-step explanation:

1. 2x - 7 = 5  

2. 2x = 5 + 7     (reverse the 7)

3. 2x = 12          (simplify)

4. 12/2               (divide number by the unknown value)

5. x= 6           (solve?)

6. 2(6) - 7 = 5    (CHECK)

Answer:

C

Step-by-step explanation:

this is because this is the only value that will yield 40 when you have 0 as a x value

40(1/4) to the 0

which is 40*1=40

if my answer helps please mark as brainliest.

Answer:

C. 40(0.25)^x

Step-by-step explanation:

Given that it is an inverse function we can see that when x = 0, y = 40 and when x = 1, y = 10. Then you look for which function fits the criteria, given that only 40(0.25)^x does it is C.

Answer:

x=2

Step-by-step explanation:

First you add 1/4 to both sides this cancels it out on the left and makes 1 on the right. Secondly you divide by 1/2. 1 divided by 1./2 is 2.

Answer:

x = 2

Step-by-step explanation:

To solve:

[tex]\frac{1}{2} x =\frac{3}{4} +\frac{1}{4}[/tex]

[tex]\frac{1}{2} x = \frac{4}{4}[/tex]

[tex]\frac{1}{2} x = 1[/tex]

[tex]x = 1 x 2[/tex]

x = 2
