Answer:
Step-by-step explanation:
Slope is m
in this case slope is -50
b is the y-int,
in this case the y-int is 8000
so your equation: y = -50x + 8000

y² - 2y - 4x + 9 = 0 (*)
a = 1 b = -2 c = -4x + 9
Δ = b² - 4ac = 4 - 4(9 - 4x) = 4 - 36 + 16x = 16x - 32

a typical car releases 36 tons of carbon dioxide and six years at a constant rate how many times will a car release in 10 years ?
Answer:
60 Tons
Step-by-step explanation:
36 divided by 6 equals 6. So that six is used for the for extra years
36+6+6+6+6
The number of tonnes of carbon dioxide released in 10 years will be 60 tonnes.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
A typical car releases 36 tonnes of carbon dioxide and six years.
Let 'x' be the amount of carbon dioxide.
At a constant rate, the number of tonnes of carbon dioxide released in 10 years will be given as,
x / 10 = 36 / 6
Simplify the equation, then we have
x / 10 = 36 / 6
x / 10 = 6
x = 60 tons
The number of tonnes of carbon dioxide released in 10 years will be 60 tonnes.

We can clearly see in the diagram that a transversal is intersecting two parallel lines.
When a transversal intersects two parallel lines, eight angles are formed.
The angles which are in the same position on same side of each line intersected by the transversal, are called corresponding angles.
Corresponding angles are congruent.
So,
Angle 6x+4° and 100° will be congruent or equal
[tex]6x+4 = 100\\6x =100-4\\6x = 96\\\frac{6x}{6} = \frac{96}{6}\\x = 16[/tex]
Hence,
The value of x is 16
675 grams of sweets were distributed among 9 children. How much sweet was given to each child?
Answer:
75 Sweets
Step-by-step explanation:
To get the answer you have to divide the number of sweets by the number of children. If there are 675 grams and 9 children, then you divide 675/9 to get your answer of 75 sweets.
Each child was given 75 grams of sweets as per linear equation when distributed.
What is a linear equation?A linear equation is an equation where the highest degree of the variable is one.
Given, there are a total of 675 grams of sweets.
There are a total of 9 children among which the sweets is to be distributed equally.
Therefore, each children will get sweets of
(675 ÷ 9) grams
= 75 grams.
Therefore, each child will get 75 grams of sweets when it is distributed equally.

Answer:

Step-by-step explanation:
The picture gives us that two sides are congruent. We can see that an angle is congruent as well because they share a common point at their tip.
If we look at just the area of intersection, it looks like an X. Think of the X as two lines intersecting. Each side equals 180°, and because both triangles are made up of those sides, we can conclude that the angles are congruent as well.

A scooter travels 30 feet in 2 seconds at a constant speed.
What is the speed of the scooter in feet per second?
Answer:
15
Step-by-step explanation:
Since it goes 30 in 2 seconds, we need to divide 30 and 2 and end up with 15.
To make sure our answer is correct we know that 15 is one second, so we can add 15+15= which will give us 30, and will also land at 2
Brainliest pls
The speed of the scooter is 15 feet per second.
To calculate the speed of the scooter in feet per second, you can use the formula:
Speed = Distance / Time
The distance traveled by the scooter is 30 feet, and the time taken is 2 seconds.
Plugging these values into the formula, we get:
Speed = 30 feet / 2 seconds
Speed = 15 feet/second
Therefore, the speed of the scooter is 15 feet per second.

The Ironman endurance race has a 2.4 miles swim. Javier can swim 0.5 miles in 20 minutes. If he can continue this pace, it will take him hours to finish the swim event.
Given :
The Ironman endurance race has a 2.4 miles swim.
Javier can swim 0.5 miles in 20 minutes.
To Find :
How much time in hours it takes to complete the race.

[tex]s=\dfrac{2.4}{\dfrac{20}{60}}\ mph\\\\s= 7.2\ mph[/tex]
Let, time taken to cover 2.4 miles is t .
So,
[tex]t = \dfrac{2.4}{7.2}\ hours\\\\t = 0.33\ hours[/tex]

=8/8
=1
The value of (f o g)(-1) is 1 if the function f(x) = 8/(x + 2) and g(x) = 4x² + 2 the answer is 1.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
Two functions:
f(x) = 8/(x + 2)
g(x) = 4x² + 2
g(-1) = 4(-1)² + 2
g(-1) = 4 + 2
g(-1) = 6
f(g(-1)) = 8/(x + 2)
f(g(-1)) = 8/(6 + 2)
f(g(-1)) = 8/8
f(g(-1)) = 1
Thus, the value of (f o g)(-1) is 1 if the function f(x) = 8/(x + 2) and g(x) = 4x² + 2 the answer is 1.

what is the answer to 4(x + 1) = 4x + 10
Answer:
No solution
Step-by-step explanation:
First we would have to see if anything has to be distributed and yes the 4 in the expression 4(x + 1) has to be distributed to the x and 1. So we would multiply the 4 by x and 1. Now we have 4x + 4 = 4x + 10. We have to get the x's on 1 side of the equation so we would do the inverse of one of the x's and we can only subtract. So we can subtract 4x on both sides. So now we have
4 = 10. That isn't a correct statement so there is no solution.
4 does not equal 10.
