x = -9 and x = 8 when y = 0 is the answer
Answer: x= -9,8
Step-by-step explanation:
x=?
y=0
y=x^2+x-72
0=x^2+x-72
0=(x+9)(x-8)
x+9=0 x-8=0
-9 -9 +8 +8
x= -9 x=8

Which is the graph of the linear equation x - 2y = 6?
Answer:
All you have to do is turn x-2y=6 into y=mx+b form. That would mean you need to get y by itself. Subtract x from 6. Then you have -2y=6-x. Now you have to divide both sides of the equation by -2. So then you have -2y/-2 = 6-x/-2. That turns out to y=3-1/2x Which is easier read by: y=1/2x - 3

Answer:
y = 15∠abc = 68°∠bac = 78°∠acb = 34°Step-by-step explanation:
It is helpful to realize that the exterior angle is equal to the sum of the remote interior angles:
146° = (5y+3)° +(4y+8)°
135 = 9y . . . . . . . . . . . . . . divide by °, subtract 11
15 = y . . . . . . . . . divide by 9
∠abc = (4y+8)° = (4·15 +8)° = 68°
∠bac = (5y+3)° = (5·15 +3)° = 78°
∠acb = 180° -146° = 34°

answer is 50
Thanks so much
Answer:
(3x +2)° + 28° = 180°
=> 3x + 30 = 180
=> 3x = 180–30
=> x = 150/3
=> x = 50

Step-by-step explanation:
3/4 (6x + 1) - 3x = 1/4 (2x - 1)
3/4 (6x + 1) - 3x = 1/4 (2x - 1) . The purpose of this question is to solve for x.
[tex]\mathbf{x = \dfrac{-4}{13}}[/tex]
Given that:
3/4 (6x + 1) - 3x = 1/4 (2x - 1)When calculating algebraic expression, we take note of integers in bracket first, then we collect the like terms in order to find the value of x.
[tex]\mathbf{\dfrac{3}{4} (6x + 1) - 3x =\dfrac{1}{4} (2x - 1) }[/tex]
Let's multiply both sides by 4 to eliminate the fraction.
[tex]\mathbf{(\dfrac{3}{4} \times 4) (6x + 1) - 3x =(\dfrac{1}{4} \times 4 ) (2x - 1) }[/tex]
[tex]\mathbf{(3) (6x + 1) - 3x =(1 ) (2x - 1) }[/tex]
Open brackets;18x + 3 - 3x = 2x - 1
By rearrangement;18x - 3x + 3 = 2x - 1
15x + 3 = 2x - 1
Collect like terms15x - 2x = - 3 - 1
13x = - 4
Divide both sides by 13[tex]\mathbf{\dfrac{13x}{13} = \dfrac{-4}{13}}[/tex]
[tex]\mathbf{x = \dfrac{-4}{13}}[/tex]

Five days a week, from Monday to Friday, Betsy takes the bus to school. Each day she has a probability of 90% of taking bus 1. If she does not take bus 1 then she will take bus 2.
What is the probability that she will take bus 1 on all five days?
Answer:
0.59
Step-by-step explanation:
Given that :
Probability of taking bus 1
P(b1) = 90% = 0.9
What is the probability that she will take bus 1 on all five days?
Five days from Monday to friday:
On Monday : p(b1) = 0.9
On Tuesday : p(b1) = 0.9
On Wednesday : p(b1) = 0.9
On Thursday : p(b1) = 0.9
On Friday : p(b1) = 0.9
Here we have an independent event:
Hence, probability of taking bus 1 on all five days :
(0.9 * 0.9 * 0.9 * 0.9 * 0.9)
= 0.59049
= 0.59

A plumber earns $50 for a repair job, plus an additional $75 per hour he works. On Tuesday, he completed 3 repair jobs and earned a total of more than $600. Part A: Write an inequality that can be used to determine h, the number of hours the plumber worked Tuesday.
Answer:
[tex]150 + 75h > 600[/tex]
Step-by-step explanation:
The inequality that can be used to determine h is shown below:-
As per the given situation, it is mentioned that a plumber could earns $50 for a repair job, so for three jobs he earned $150 as a total amount
Now
We presume h be the number of hours
Also he earns additional $75 per hour worked so $75
Total amount is $150 + $75h)
The total amount is more than $600
So, the inequality equation is as given below:
[tex]150 + 75h > 600[/tex]

-4 = -1/7(-2)
-4 = -2/7
-4 + -2/7 = b
b = -6/7
