Answer:
Step-by-step explanation:
Find the roots of x² - 17x - 60
Quadratic formula
x = [17 ± √(17² – 4·1(-60))] / [2·1]
= [17 ± √529] / 2
= [17 ± 23] /2
= -3, 20
x² - 17x - 60 = (x+3)(x-20)
Answer:
(x+3)(x-20)
Step-by-step explanation:
x^2+3x-20x-60
x(x+3)-20(x+3)
= (x+3)(x-20)

Write down a different ratio equivalent to 42 : 12
Step-by-step explanation:
simplify it maybe
try it with 2 and 3
Answer:
Another ratio that is equivalent to this is 7:2.
Step-by-step explanation:
If we divide both sides by 6, we get 7 and we get 2. Since 42 comes first, we put the 7 in place of the 42. Then we replace 12 with 6. After this, we get the ratio 7:2.

Write an equation in slope-intercept form for the line that passes through the given point and is parallel to the graph of the equation.
(4,−3); y=3x−5
Answer:
[tex]y=3x-15[/tex]
Step-by-step explanation:
Slope intercept form: [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of y when the line crosses the y-axis)
1) Find the slope of the line ([tex]m[/tex])
When it comes to parallel lines, they will always have the same slope but different y-intercepts. The given equation is [tex]y=3x-5[/tex]. Because 3 is in the place of m, we know that the slope of the line is 3. Therefore, the slope of the line parallel to it will also be 3. So far, this is what our equation looks like:
[tex]y=3x+b[/tex]
2) Find the y-intercept ([tex]b[/tex])
To find the y-intercept, we plug the given point (4,-3) into the equation we currently have and solve for b.
[tex]y=3x+b\\-3=3(4)+b\\-3=12+b[/tex]
Subtract both sides by 12
[tex]-3-12=12+b-12\\-15=b[/tex]
Therefore the y-intercept of our line is -15. Plug -15 back into the original equation as b.
[tex]y=3x+(-15)\\y=3x-15[/tex]
I hope this helps!

Write an expression that represents the height of a tree that begins at 9 feet and increases by 3 feet per year. Let y represent the number of years.
Answer:
h=3y+9
Step-by-step explanation:
We will write an expression using the y=mx+b format.
h in this case will be the height at any given year.
3 is the rate at which the three grows, y will represent any given year.
9 is the starting rate, or your y intercept.
Answer:
h=3y+9
Step-by-step explanation:

Answer:
A=80
B=31
C=64
Step-by-step explanation:
A, 69, and b will equal 180 since it forms a straight line
A+69+b=180
to solve for A we subtract 53+47 from 180 and get 80
80+69+b=180
to get B we subtract 80+69 from 180 and get 31
to get c we add 85+b and subtract it from 180 getting c=64
Answer:
Hey it's me again the life saver ;)
To find b we can use the linear pair property but since only 1 angle is given, we owuld need at least 2 angles on this situation to find b so, to do that we are first going to find a
a=>
53 + 47 + a = 180
a=180 - 100
a=80°
Now to find b=>
80 + 69 + b =180 (Because of Linear pair property)
b = 180-149
b=31°
Now that we have got b, to solve c, we can again use the sum of all angles in a triangle are 180°
c=>
31 + 85 + c =180
c=180 - 116
c=64

what is the coefficient of x in (x +3) (x-1)
2
Step-by-step explanation:
Solving; ( x + 3 ) ( x - 1 )
x ( x - 1 ) + 3 ( x - 1 )
x² - x + 3 ( x - 1 )
x² - x + 3x - 3
x² - 2x - 3
The coefficient of x in x² + 2x - 3 is 2

Points a and b both lie on the line y=3x+7. Work out the missing y coordinate for a and the missing x coordinate for B?
Answer:
y coordinate = 13
x coordinate = -1
Step-by-step explanation:
Trail and error lol
The missing [x] - coordinate of point A is -2 and point B is -1.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have the equation of line as -
y = 3x + 7
Refer to the graph attached of the equation -
y = 3x + 7.
Since, the graph is not given we will mark two random points on it. It can be seen that the missing [x] - coordinate of point A is -2 and point B is -1.
Therefore, the missing [x] - coordinate of point A is -2 and point B is -1.
