Answer:
1. 1.25 + .20x = 6
Step-by-step explanation:
You will most likely just buy one drink and multiple ounces of salad with the 6 dollars you have to purchase a whole meal.
.20x, where x equals how many ounces you purchase
1.125 for the one drink
When set equal to 6 dollars you are able to find how much salad plus a drink you can purchase in total.

If 5 bats and 4 balls weigh 58 kg, and 4 bats and 5 balls weigh 50 kg, then how much does a bat weigh?
The bat weighs 10kg.
Two equations can be gotten from the question:
5a + 4b = 58 equation 1
4a + 5b = 50 equation 2
Where:
a = weight of bats
b = weight of balls
The two equations are simultaneous equations and would be solved using the elimination method.
In order to determine the weight of balls, take the following steps:
Multiply equation 1 by 4 and equation 2 by 5
20a + 16b = 232 equation 3
20a + 25b = 250 equation 4
Subtract equation 3 from 4
18 = 9b
Divide both sides of the equation by 9
b = 2kg
In order to determine the weight of bats, take the following steps:
Replace for b in equation 1
5a + 4(2) = 58
5a + 8 = 58
5a = 58 - 8
5a = 50
Divide both sides of the equation by 5
a = 10kg

The value of y is directly proportional to the value of x. When x=3.5, the value of y is 14. What is the value of y when x = 28?
Answer:
x = 7
Step-by-step explanation:
y = 14
14 x 2 = 28
Therefore:
3.5 x 2 = 7
Value of y is 112 when value of x is 28
Given that;
Value of y is 14 when x = 3.5
Find:
Value of y when value of x = 28
Computation:
We know that, y is directly proportional to x
So,

What is the slope of the line whose equation is 2x+3y = -12?
Answer:
slope = - [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x + 3y = - 12 ( subtract 2x from both sides )
3y = - 2x - 12 ( divide all terms by 3 )
y = - [tex]\frac{2}{3}[/tex] x - 4 ← in slope- intercept form
with slope m = - [tex]\frac{2}{3}[/tex]
What is the rate of change for the equation y = 2x + 100?
+
The rate of change is
h
Answer:
Rate of change = 2
Step-by-step explanation:
The rate of change is equivalent to the slope of the line !
A line is written:
y=mx+b
"m" is the slope, and "b" is the y-intercept !
The line you gave was "y=2x+100"
The slope, or "m," in your equation, would be 2 !

A proportional relationship goes through the point (4, 10). Explain how to write a function in the form y = mx for this relationship.
Answer:
m = 5 / 2
Step-by-step explanation:
Given
(4, 10)
Here,
x=4 and y=10
Given equation,
y=mx _ equation 1
putting the value of x and y in equation 1. we get,
y = mx
or, 10 = m4
or, 10 / 4 = m
or, 5 / 2 = m
therefore, m = 5 / 2

An ostrich was 960meters east of its nest. It ran west at a constant velocity for 160seconds. In that time, it ran halfway to its nest. What was its velocity?
Answer is 3 m/s.
Step-by-step explanation:-The ostrich ran at a constant velocity, so it's velocity was :
[tex]velocity = \frac{distance}{time} [/tex]
It is said that the bird ran for 160 seconds and it made it half-way to its nest, so the distance was :
[tex]distance = \frac{960 \: metres}{time} [/tex]
[tex]distance = 480 \: metres[/tex]
And the velocity is :-
[tex]velocity = \frac{480 \: metres}{160 \: seconds} [/tex]
[tex]velocity = 3 \: m/s[/tex]
Therefore, the ostrich ran at a velocity of 3 m/s .

line l contains points (-2,4) and (1,-9). Point P has coordinates (14,-6) answer
We are given a line and a point, I assume that we want to see if the point is on the line or not.
We will see that the point does not belong to the line.
First, let's find the equation of the line.
A general line can be written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If the line passes through points (x₁, y₁) and (x₂, y₂), then the slope can be computed as:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Here we know that our line passes through the points (-2, 4) and (1, -9). Then the slope is:
[tex]a = \frac{4 - (-9)}{-2 - 1} = \frac{13}{-3} = -\frac{13}{3}[/tex]
Then our line is something like:
[tex]y = -\frac{13}{3} *x + b[/tex]
To find the value of b, we can use one of the two points that we know that are on the line.
For example, the point (-2, 4) means that when x = -2, we must have y = 4.
Replacing that in the equation we get:
[tex]4 = -\frac{13}{3} *(-2) + b\\\\4 = \frac{26}{3} + b\\\\4 - \frac{26}{3} = b\\\\\frac{-14}{3} = b[/tex]
Now we can write the line equation as:
[tex]y = -\frac{13}{3} *x - \frac{14}{3}[/tex]
Now we need to see if the point (14, -6) belongs to the line.
To see this, we evaluate the line in x = 14.
[tex]y = -\frac{13}{3} *14 - \frac{14}{3} = -\frac{196}{3}[/tex]
This is different than -6, so the point does not belong to the line.

What is the = to 5x+ 7 =42 please give details
Answer: x = 7
Step-by-step explanation:
5x + 7 = 42
We then take 7 away from both sides:
5x = 35
Then, we need to make it so x = answer. To make 5x into x, we divide by 5 meaning that we next need to divide both sides by 5.
x = 7
