The equation, y=4x+15 represents the relationship shown in the graph.
Finger [1]3 years ago
4 0

Answer:

4. -4x+y=15

Step-by-step explanation:

We have been given a graph of a linear function and we are asked to find the correct equation representing the relationship shown in the graph.

Since we know that the standard form of an equation is in form: Ax+By=C, where A, B and C are integers.

First of all we will find the slope of our line and write equation of line in slope-intercept form. Then we will change it into standard form.

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{23-15}{2-0}

m=\frac{8}{2}=4

Slope of our line is 4. We can see that y-intercept (b) is 15. Now let us write equation of our line in slope-intercept form.

y=mx+b

y=4x+15

Now we will change our given equation into standard form by subtracting 4x from both sides of our equation.

-4x+y=4x+15-4x

-4x+y=15    

Therefore, the equation -4x+y=15 represents the relationship shown in the graph in standard form and 4th option is the correct choice.

A cardboard box without a lid is to be made with a volume of 44 ft3. Find the dimensions of the box that requires the least amou
-BARSIC- [3]

Answer:

x =  3.53 ft

y - 3.53 ft

z = 3.53 ft

Step-by-step explanation:

given details

volume = 44 ft^3

let cardboard dimension is x and y and height be z

we know that area of given cardboard without lid is given as

A = xy + 2xy + 2yz

xyz   = 44 ft^3

To minimize area we have

A = xy + 2x (44/xy) + 2y(44/xy)

A = xy + (44/y) + (44/x)

we have

Ax = y - \frac{44}{x^2}

0 = yx^2 = 44................1

Ay = x - \frac{44}{y^2}

0 = x - \frac{44}{y^2}

xy^2 = 44 ..............2

from 1 and 2

yx^2 = xy^2

xy(y-x) = 0

xy = 0 or y = x

from geometry of probelem

x ≠ 0 and y ≠ 0

so y = x

x^3 = 44

x =  3.53 ft = y

z = 44/xy = 3.53

A hole needs to be at least 40 feet below ground level. This means it needs to be more than 2 times its current depth.
Alex Ar [27]

The current depth of the hole is at least 20 feet below ground level.

Inequality is an expression that shows the non equal comparison of numbers and variables.

Let d represent the current depth of the hole.

To be at least 40 feet below ground level, he need more than 2 times its current depth.

2d < -40

d < -20

Hence the current depth of the hole is at least 20 feet below ground level.

This is a problem that I have to solve with matrixes, Please show me all of the work. I will award brainliest.
Elina [12.6K]

Answer:

The total points by Washington High School =  162 points

The total points by  Johnson High School   =  159 points

The total points by  Roosevelt High School =  108 points

The total points by  Lewis High School =  196 points

Washington High School  has WON the meet.

Johnson High School came second.

The difference in the points= 2 points

Step-by-step explanation:

Points awarded for first place = 10 points

Points awarded for second place = 8 points

Points awarded for third place = 7 points

About Washington High School

10 first places  = 10 x ( 10) = 100 points

6 second places  = 6 x ( 8) = 48 points

2 first places  = 2 x ( 7) = 14 points

So, the total points by  Washington High School  = Sum of all points  

=  100 + 48 + 14   =  162 points     .............. (1)

About Johnson High School

8 first places  = 8 x ( 10) = 80 points

9 second places  = 9 x ( 8) = 72 points

1 first places  = 1 x ( 7) = 7 points

So, the total points by  Johnson High School  = Sum of all points  

=  80 + 72 + 7   =  159 points    .............. (2)

About Roosevelt High School

4 first places  = 4 x ( 10) = 40 points

5 second places  = 5 x ( 8) = 40 points

4 first places  = 4 x ( 7) = 28 points

So, the total points by  Roosevelt High School  = Sum of all points  

=  40 + 40 + 28   =  108 points  .............. (3)

About Lewis High School

3 first places  = 3 x ( 10) = 30 points

3 second places  = 3 x ( 8) = 24 points

6 first places  = 6 x ( 7) = 42 points

So, the total points by  Lewis High School  = Sum of all points  

=  30 + 42 + 24   =  96 points      .............. (4)

Now, comparing all four equation, we get that:

Washington High School  has WON the meet.

Johnson High School came second.

The difference in the points  = 162 - 159 = 2 points

How do you divide fractions the way they taught it on 7th grade math edgenuidy * sorry I spelt it wrong it wouldn’t let me spell
Aleksandr [31]

Answer:

I'm old and the way I was taught about fraction division was:

INVERT AND MULTIPLY.

SO: (5/8) divided by (1/4) equals

(5/8) multiplied by (4/1) which equals (20/8) or 2.5
