The distance a spring will stretch varies directly with how much weight is attached to the spring. If a spring stretches 6 inche

Iteru [2.4K]

The correct answer is:

C.4.1 in

Explanation:

We will use a proportion for this problem.

In the first ratio, we have 6 inches: 80 pounds. This can also be written as 6/80.

For the second ratio, we do not know the length; this is x. The weight is 55; this gives us x/55.

This makes our proportion

6/80 = x/55

Cross multiplying, we have

6(55) = 80(x)

330 = 80x

Divide both sides by 80:

330/80 = 80x/80

4.125 = x

This means the answer is 4.1.

Find the slopes of the liner functions

LuckyWell [14K]

Answer:

The slope of the line given by the linear equation is -2

The slope of the line shown in the graph is -1

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

m is the slope

b is the y-intercept

The rule of the slope of a line is m = $\frac{y2-y1}{x2-x1}$ , where

(x1, y1) and (x2, y2) are two points lie on the line

Let us use these rules to answer the question

∵ The linear equation is y = -2x + 7

→ By comparing it with the form of the linear equation above

∴ m = -2

∵ m is the slope of the line represented by the given equation

∴ The slope of the line given by the linear equation is -2

From the given figure

∵ The line passes through points (6, 0) and (0, 6)

∴ x1 = 6 and y1 = 0

∴ x2 = 0 and y2 = 6

→ Substitute them in the rule of the slope above to find it

∵ m = $\frac{6-0}{0-6}=\frac{6}{-6}$

∴ m = -1

∵ m is the slope of the line shown in the graph

∴ The slope of the line shown in the graph is -1

ASAP HELPPPPPPPPPPPPPP MEEEEB PLEASE

Andru [333]

Answer:

250 questions

Step-by-step explanation:

65 is equal to 26% of the total number of questions so:

65 / total number of questions (x) is equivalent to 26 / 100

(65 and 26 are a fraction of the whole thing. it doesn't matter whether they go on the numerator or denominator, as long as they are either both on one or the other)

65/x = 26/100

you can simplify this into

26x = 6500

/26 /26

then you divide by 26 on both sides to isolate the variable

x = 250

Determine the value(s) of k such that the system of linear equations has the indicated number of solutions. (Enter your answers

Ratling [72]

Answer:

k=3

Step-by-step explanation:

The given system of equations are

$9x+ky=24$

$kx+y=8$

We need to find the value of k if the given system of equation have infinite number of solutions.

If two equations $a_1x+b_1y+c_1=0$ and $a_2x+b_2y+c_2=0$ have infinite number of solutions, then

$\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}$

Using this we get

$\dfrac{9}{k}=\dfrac{k}{1}=\dfrac{-24}{-8}$

$\dfrac{9}{k}=\dfrac{k}{1}=3$

$\dfrac{k}{1}=3$

$k=3$

Therefore, the value of k is 3.

What are the x and y- intercepts for the line 4(y+3)=−2(x+6)?

Elodia [21]

X - intercepts y = 0, then
4(0+3)=−2(x+6)
12 = -2x -12
2x = -24
x=-24/2
x = -12

y- intercepts x = 0 then
4(y+3)=−2(0+6)
4y +12 = -12
4y = -24
y = -24/4
y = -6
