If 7/35 = 4/y, what is y?

Answers

Answer:

y = 20

Step-by-step explanation:

[tex] \frac{7}{35} = \frac{4}{y} [/tex]

First of all cross multiply

That's

7y = 140

Divide both sides by 7

That's

[tex] \frac{7y}{7} = \frac{140}{7} [/tex]

We have the final answer as

y = 20

if
f(x)=x^2+2x-4
and
g(x)=3x+1
find
f(g(x))=__x^2+__x+__
​

Answers

Step-by-step explanation:

f(x) = x² + 2x - 4

g(x) = 3x + 1

f(g(x)) = f(3x + 1)

f(3x + 1) = [3x + 1]² + 2[3x + 1] - 4

= 9x² + 6x + 1 + 6x + 2 - 4

= 9x² + 12x -1

Tell whether the blue figure is a translation of the red figure.
The blue figure !
I a translation of the red figure.

Answers

Answer:it is a translation

Step-by-step explanation:a translation is just a movement up down left or right not diagonal you’re just moving it up down left or right across the grid

Answer:

Yes

Step-by-step explanation:

Because a translation moves a shape up, down, or from side to side but it does not change its appearance in any other way. The translation is an example of a transformation. A transformation is a way of changing the size or position of a shape. Every point in the shape is translated at the same distance in the same direction.

Erica has saved $2400.if she spends $45 per day then what is the first day that her balance will be $500 or less

Answers

Answer:

The 43rd day of spending $45.

Step-by-step explanation:

Let the number of days = x.

If she spends $45 per day, then in x days she spends 45x.

She starts with $2400, so 45x is subtracted from 2400.

2400 - 45x < 500

Subtract 2400 from both sides.

-45x < -1900

Divide both sides by -45. Remember to change the direction of the inequality sign when multiplying or dividing by a negative number.

x > 42.2

Answer: The first day is the 43rd day of spending $45.

A man (M) is standing halfway between a tree (T) and a lamppost (L). What is the value of x?
T
M
L
(2x + 8) m
(3x – 2) m
I don't understand what I have to do and how to get the answer is there anyway someone can tell me???

Answers

Answer :

The value of x is 10.

Explanation :

Given that,

TM = (2x+8) m

ML = (3x-2) m

If a man (M) is standing halfway between a tree (T) and a lamppost (L).

The half distance is TM and half distance is TL.

So, Both half distance will be equal.

We need to calculate the value of x

Using given data

[tex]TM=ML[/tex]

Put the value into the formula

[tex]2x+8=3x-2[/tex]

[tex]2x-3x=-8-2[/tex]

[tex]-x=-10[/tex]

[tex]x=10[/tex]

Hence, The value of x is 10.

An object is traveling at a steady speed of 9 4/5 mi/h. ​ How long will it take the object to travel 2 1/5 miles? ​First round to the nearest integer to find the estimated answer. Then find the exact answer.

Answers

Answer:

Time taken by the object = 14 minutes

Step-by-step explanation:

Speed of an object = [tex]9\frac{4}{5}[/tex] miles per hour ≈ 9.8 miles per hour

Distance covered by the object = [tex]2\frac{1}{5}[/tex] miles ≈ 2.2 miles

Formula to calculate the distance in the time 't' is,

Time taken by the object = [tex]\frac{\text{Distance traveled}}{\text{Speed of the object}}[/tex]

                                          = [tex]\frac{2.2}{9.8}[/tex]

                                          = 0.2245 hours

                                          = 13.47 minutes

                                          ≈ 14 minutes

Therefore, distance traveled by the object to cover 2.2 miles = 14 minutes.

x = 7 + 3y
5x + 6y = 14
Which ordered pair (x,y) is the solution to the system of equations above?

Answers

Given Equation:

x = 7 + 3y

or, x - 3y - 7 = 0 ........ (i)

5x + 6y = 14

or, 5x + 6y - 14 = 0 .........(ii)

To Find:

The value of x and y.

Solution:

By dividing eq. ii by 2, we get

5/2x + 3y - 7 = 0 ........ (iii)

By adding eq. i and eq. iii, we get

15/2x = 0

or, x = 0 ........(iv)

By putting eq.(iv) in eq. (i), we get

0 - 3y - 7 = 0

or, -3y = 7

or, y = -7/3

Answer: ( 0, -7/3 )

The value of x and y is 0 and -7/3 respectively.

(0,-7/3) is the answer please press thanks
