Identify the slope and y-intercept of the line. y = 4x − 11<br> slope=<br> y-intercept (x, y) =

MArishka [77]

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

From the question the equation is

y = 4x − 11

Comparing with the general equation above

<h3>Slope = 4</h3><h3>y - intercept = - 11 or ( 0 , - 11)</h3>

A batting machine uses an automatic baseball feeder. During baseball

Inessa05 [86]

The feeders in battling machine are represented in proportions and fractions.

The equation that represents the problem is: $\mathbf{\frac 16x + 15 = \frac 23x}$
The feeder can hold <em>30 baseballs</em>, when full

The given parameters are:

<em /> $\mathbf{Initial = \frac 16x}$ <em> ------ 1/6 full</em>

<em /> $\mathbf{Additional = 15}$ <em> --- baseballs added</em>

<em /> $\mathbf{Final = \frac 23x}$ <em> ---- 2/3 full</em>

<em />

So, the equation that represents the problem is:

$\mathbf{Initial + Additional = Final}$

So, we have:

$\mathbf{\frac 16x + 15 = \frac 23x}$

The number of baseballs it can hold is calculated as follows:

$\mathbf{\frac 16x + 15 = \frac 23x}$

Multiply through by 6

$\mathbf{x + 90 = 4x}$

Collect like terms

$\mathbf{4x - x = 90 }$

$\mathbf{3x = 90 }$

Divide through by 3

$\mathbf{x = 30 }$

Hence, the feeder can hold 30 baseballs, when full

PLZ HELP I BEEN SUCK FOE SO LONG PLZ RIGHT ANSWER I WILL CRY

mel-nik [20]

Answer:

40 students

Step-by-step explanation:

In this problem, one is given the ratio ( 8 : 3 ), since a ratio is another way of writing a fraction one can rewrite it as; $\frac{8}{3}$ (8) represent the number of students who want to learn about magnets, and (3) represents the number of students who want to learn about magic tricks.

In the problem, it is also given that 25 more students wanted to learn about magnets compared to magic tricks. If one uses the parameter (x) to represent the factor by which the fraction $\frac{8}{3}$ is reduced, then one can get the equation;

8x = 3x + 25

Use inverse operations to solve,

8x = 3x + 25

-3x

5x = 25

/5

x = 5

Substitute back in to find out how many students want to learn about magnets,

8x

= 8(5)

= 40
