Answer:
2= 95 degrees
3= 25 degrees
1= 60 degrees
5= 25 degrees
4= 95 degrees
Step-by-step explanation:
2) Straight line is 180 degrees so
180-85=95 degrees
3) I got 25 degrees because it's a corresponding angle of X, which is parallel to 25.
1) A triangle is always 180 degrees, 95+25=120 180-120=60
5) Its another corresponding angle to 25
4) Straight line is 180 degrees 60+25=85 180-85=95
Or you could of worked out the bottom 85 and minus it from 180 which will also correspond to 4

Consider the following pair of equations:
y = 3x + 3
y = x − 1
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.
Answers
Answer:
(-2, -3)
Step-by-step explanation:
We are given y = 3x + 3 and y = x - 1.
We can substitute y = x + 1 into the y value for y = 3x + 3, so
x - 1 = 3x + 3 Now, we just subtract x from both sides.
-1 = 2x + 3 We subtract 3 from both sides.
-4 = 2x
2x = -4 We divide both sides by 2
x = -2 Now we have our x value - (-2, y)
Let's substitute the x value into both of the equations given.
1st equation:
y = 3(-2) + 3
y = -6 + 3
y = -3
2nd equation:
y = (-2) - 1
y = -3
We now know that both equations give us the same y value when x = -2 is substituted, therefore our solution is:
(-2, -3)
The solution for the pair of equations is (-2,-3).
What is a system of equation?A system of equations is a set or collection of equations that you deal with all together at once. For a system to have a unique solution, the number of equations must equal the number of unknowns.
For the given situation,
The pair of equations are
y = 3x + 3 ------- (1)
y = x − 1 -------- (2)
Substitute the equation 2 in equation 1, we get
⇒ [tex]x-1=3x+3[/tex]
⇒ [tex]3x-x=-1-3[/tex]
⇒ [tex]2x=-4[/tex]
⇒ [tex]x=-2[/tex]
Now substitute x in equation 2,
⇒ [tex]y=-2-1[/tex]
⇒ [tex]y=-3[/tex]
Hence we can conclude that the solution for the pair of equations is (-2,-3).

Solve each system by substitution.
y = 2x + 5
3x - y= -6
Answers
To solve this, because y is equal to 2x+5, you can substitute 2x+5 into the bottom equation for y.
You now have 3x - (2x + 5) =-6
This can be solved like a normal equation. Multiply each term in the parenthesis by -1.
3x - 2x - 5 = -6
Subtract 2x from 3x
x - 5 = -6
Add 5 to both sides
x=-1
Now you can solve for y by plugging -1 in for x in either equation. Im going to use the top one.
y= 2(-1)+5
y= -2+5
y=3
You can check your answer by plugging in the values for x and y into both equations and making sure both sides equal each other.

Answers
Answer: 8000
Step-by-step explanation:
From the question, we are informed that the expression 10³ × 2^w models the population of the bacteria after w weeks.
The number of bacteria that will be present in 3 weeks will then be:
= 10³ × 2^w
= 10³ × 2³

Step-by-step explanation:
Factoring will reveal the solution. So we divide the equation by the greatest common factor of the terms and use that factor as the coefficient. In this case the greatest common factor is just x.
2x^2+5x
x(2x+5) so the equation will equal zero when either of those expressions is zero because zero times anything is zero. x=0 and x=-5/2
Answer:
[tex]x = 0, -\frac{5}{2}[/tex]
Step-by-step explanation:
First move all terms to one side of the equation to set them equal to 0
That is already done in your problem
The try to factor, if possible. In your case, factor out x
x(2x + 5) = 0 Now, use the property that says if AB = 0, then A = 0 or B = 0 or both A and B equal 0
So, x = 0 or 2x + 5 = 0
2x = -5
x = [tex]-\frac{5}{2}[/tex]
Always check your results in the original equation to see if they work
[tex]2(0^{2} + 5(0) = 0 + 0 = 0\\[/tex]
and [tex]2(-\frac{5}{2} )^{2} + 5(-\frac{5}{2} )\\ = 2(\frac{25}{4} ) - \frac{25}{2} \\ = \frac{25}{2} - \frac{25}{2} = 0[/tex]
Both results make the equation true, so [tex]x = 0, -\frac{5}{2}[/tex]

Answer:
a) y = 4x - 2b) y = 3x + 2c) y = 2x - 6Step-by-step explanation:
a)
The slope as per two ordered pairs (-2, -10), (0, -2)
m = (-2 - (-10))/(0 - (-2)) = 8/2 = 4The y-intercept is -2
The equation for this function:
y = 4x - 2b)
The slope is
m = 3The line passes through (1, 5)
The line is:
y - 5 = 3( x - 1) in point-slope formy = 3x +2 in slope-intercept formc)
The slope as per points on the graph (3, 0), (4, 2)
m = (2 - 0)/(4 - 3) = 2The line in point slope form using point (3, 0):
y = 2(x - 3)The line in slope-intercept form:
y = 2x - 6a) substitute m = 4 and c = - 2 into the slope intercept equation, thus, the equation of the line is y = 4x - 2
The answer is y = 4x - 2
b) Let's begin by listing out the given information:
The line has a slope of 3
The equation of the line becomes:
[tex]y = mx + b \\ m = 3 \\ y = 3x + b[/tex]
The line passes through point (1, 5).
We will obtain the equation using the point-slope formula, we have:
[tex]y - y1 = m(x - x1) \\ (x1 \: y1) = (1 \: 5) \\ y - 5 = 3(x - 1) \\ y - 5 = 3x - 3 \\ y = 3x - 3 + 5 \\ y = 3x + 2[/tex]
Therefore, the equation of the straight line is y = 3x + 2
c) we use that point and the slope to replace in the expression:
[tex]y - y1 = m(x - x1)[/tex]
That is:
[tex]y - 0 = 2(x - 3) \: \: y = 2x - 6[/tex]
y = 2x - 6 is the answer

Answer:
The equation is:
y = -15*x + 1200
and:
a = 120
b = 70
c = -1500
Step-by-step explanation:
This seems to be a linear relationship.
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Here we know that our line passes through the points (60, 300) and (20, 900)
Then the slope of this line is:
a = (900 - 300)/(20 - 60) = 600/(-40) = -15
Then this line is something like:
y = -15*x + b
To find the value of b, we know that this line passes through the point (60, 300) then when x = 60, we have y = 300.
Replacing these values in the above equation we get:
300 = -15*60 + b
300 + 15*60 = b = 1200
Then:
y = -15*x + 1200.
Now that we have this equation, we can complete the table.
a is the value for y, when x = 72
Then we can replace x by 72 in the above equation:
a = -15*72 + 1200 = 120
a = 120
b is the value of x when y = 150, then we need to replace y by 150
150 = -15*b + 1200
150 - 1200 = -15*b
(150 - 1200)/-15 = b = 70
then:
b = 70
c is the value of y when x = 180, then we need to replace x by 180.
c = -15*180 + 1200
c = -1500
find the value of x .
