What number needs to be added to 5 and 3 so that the ratio of the first number to the second becomes 3:2?
sukhopar [10]

Answer:

7

Step-by-step explanation:

x + 3 : x + 8 : : 2 : 3

(x + 3) \times 3 = (x + 8) \times 2 \\ 3x + 9 = 2x + 16 \\ 3x - 2x = 16 - 9 \\ x = 7 \\ x + 3 = 7 + 3 = 10 \\ x + 8 = 7 + 8 = 15 \\  

10 : 15

raketka [301]
Green family=15n
n is number of hours
Bryant family= 40x
x is number of hours
15n+40x=1450L
n+x=55
use simultaneous equations
(15n+40x=1450)-(15n+15x=825)
25x=625
x=25hours
n=55-x
n=55-25=30hours

Write an equation of a line that passes through the point (4, 3) and is perpendicular to the graph of the equation y=-1/3 +4.​
likoan [24]

Answer:

y=3x-9

Step-by-step explanation:

Hi there!

we are given a point (4,3), and a line (y=-1/3x+4)

Perpendicular lines have slopes that are negative and reciprocal; if they are multiplied together, the result is -1

first, let's find the slope of the new line.

we can find it with this formula: (m=slope)

-1/3m=-1

multiply both sides by -3

m=3

here's our equation so far, written in y=mx+b form, where m is the slope and b is the y intercept

y=3x+b

we need to find b

Because the line passes through the point (4,3), we can use it to find b

substitute x as 4 and y as 3

3=3(4)+b

multiply

3=12+b

-9=b

substitute into the equation

<u>y=3x-9</u>

Hope this helps!

What is the answer plz help!!!

Answer:

  B.  horizontal stretch by a factor of 3

Step-by-step explanation:

Replacing x by x/k in a function causes its graph to be stretched horizontally by a factor of k. (This makes sense because it means x needs to be k times as large to give the same argument to the function.)

Here, the value of k is 3, so the function graph is horizontally stretched by a factor of 3.

Find the distance between the two points rounding to the nearest tenth
mixas84 [53]

Answer:

8.54

Step-by-step explanation:

formula:

d=\sqrt{(x2-x1)^2 + (y2-y1)^2}

d=\sqrt{(-4 - (-7))^2 + (0-(-8))^2}

d=\sqrt{3^2 + 8^2}

d=\sqrt{9 + 64}

d=\sqrt{73}

d= 8.54
