The Hoskins family spend $600 per month on groceries for their family. If this is 15% of their monthly budget, what is there mon
Varvara68 [4.7K]

Hi!

We will find the monthly budget using proportions, like this:

15% = 0,15___________600$

100% = 1_____________x$

__________________________

x = (600*1)/0,15

x = 600/0,15

x = 4000

Their monthly budget is 4000$.

Hope this helps!

Question 12(Multiple Choice Worth 1 points)
daser333 [38]

The equation of a line is y=-1/4x-7, (option 1)

<h3>What is the equation of a line? </h3>

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis.

<h3>How do you find the equation of a line?</h3>

Write the equation in the form y = mx + b to find the slope m and the y-intercept. This will allow you to graph the equation using the slope and y-intercept.

Given:-

Equation of the line is y=4x+8 

The point through which the line passes (-8,4).

here the slope of the line is m1=4

To find the perpendicular line we know the formula

m1*m2=-1

By putting the value of m1 we get m2= -1/4

By using the one-point formula of the line we have

=>(y-y1)=m2*(x-x1)

By putting the values of y1 and x1 we get

(y1,x1)=(-8,4)

=>(y+8)=-0.25*(x-4)

y+0.25x+7=0

Hence the desired equation of the line is y=-1/4x-7

Tina is making a frame for a picture she drew. The length of the picture is 11 1/9 inches, and the width of the picture is 7 1/4
77julia77 [94]

Answer:

3 31/36 inches

Step-by-step explanation:

11 1/9 = 100/9

7 1/4 = 29/4

100/9 = 400/36

29/4 = 261/36

400/36 - 261/36 = 139/36

139/36 = 3 31/36

What are the first four solutions to the sequence: f(1) = 4 and f(n) = 2*f(n-1)+3
Marrrta [24]
F(1) = 4 is given


f(2) = 2*f(2-1)+3
= 2*f(1)+3
= 2*4+3
= 8+3
= 11
f(3) = 2*f(3-1)+3
= 2*f(2)+3
= 2*11+3
= 22+3
= 25
f(4) = 2*f(4-1)+3
= 2*f(3)+3
= 2*25+3
= 50+3
= 53
f(5) = 2*f(5-1)+3
= 2*f(4)+3
= 2*53+3
= 106+3
= 109

f(1) = 4
f(2) = 11
f(3) = 25
f(4) = 53
f(5) = 109
