7 + 3 (2x - 5) = 3x + 7
Answer:
x = 5
Step-by-step explanation:
Given
7 + 3(2x - 5) = 3x + 7 ← distribute parenthesis and simplify left side
7 + 6x - 15 = 3x + 7
6x - 8 = 3x + 7 ( subtract 3x from both sides )
3x - 8 = 7 ( add 8 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
f(x) = 2x2 + 12x + 16
Answer:
[tex]x=-2;x=-4[/tex]
Step-by-step explanation:
The solution of the quadratic equation f(x) = 2x² + 12x + 16 will be negative 2 and negative 4.
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.
It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The function is given below.
f(x) = 2x² + 12x + 16
The root of the equation will be given as,
f(x) = 0
2x² + 12x + 16 = 0
x² + 6x + 8 = 0
x² + 4x + 2x + 8 = 0
x(x + 4) + 2(x + 4) = 0
(x + 4)(x + 2) = 0
x = -2, -4
The solution of the quadratic equation f(x) = 2x² + 12x + 16 will be negative 2 and negative 4.

Your pay rate is $20 per hour and you have a weekly pay period. You have worked overtime and accumulated 50 hours for the week. You get paid time and a half for overtime hours. Calculate your gross pay. *
Answer:
$1200 gross pay
Step-by-step explanation:
if you worked 40 hours normally and had 10 hours over time, that equation for the gross pay would be X = 20(40) + 30(10)
X = 20(40) + 30(10)
X = 800 + 300
X = 1200
The Johnson family pays 1,783 per month for rent. If the cost of their rent remains the same, how much will they pay for rent over 15 years?
Answer:
1 year= 12 months
1 months rent=1783
1783x12=21396
15 years = 180 months
the equation would be
1783x180=320940
or
21396x15= 320940

Can anyone help me with this question? I can’t find the answer for the ? Box
The question(s) are :
-4 - ? = -7
? - (-3) = 5
All we need to do is get the ? by itself in both equations.
-4 - ? = - 7
-? = -7 + 4
-? = -3
? = 3
? - ( -3) = 5
? + 3 = 5
? = 5 - 3
? = 2
Answer:
First ?: 3
Second ?: 2
Step-by-step explanation:
Do the inverse operation of what is shown to get the answer.
First ?:
-4 - ? = -7
-7 + 4 = -?
-3 = -?
3 = ?
Second ?:
? + 3 = 5 (Two negatives in a row make a positive.)
5 - 3 = ?
2 = ?

Find x and the size of each angle
in this triangle.
6x + 20
4.2
80 - 2.0
Answer:
6x + 20 + 4x + 80 - 2x=180
6x + 4x - 2x= 180 - 80 - 20
8x = 80
x = 10
The value of x in the triangle is 10, the value of each angle are; 80, 40 , 60 respectively
How can the value of x be gotten?The total angle can be added as
note that the total angle in the triangle is 180
[tex]6x + 20 + 4x + 80 - 2x=180[/tex]
[tex]6x + 4x - 2x= 180 - 80 - 20[/tex]
[tex]8x = 80x = 10[/tex]
Then we can know the angles as ;

What is the slope represented in the table ?
Answer:
slope:2
Step-by-step explanation:
Slope is rise/run, or change in y/change in x.
With that being said, we only need two points to solve this.
Let's take the points (0,7) and (1,9)
The formula for finding the slope from two points is m=(y2-y1)/(x2-x1).
M is the slope.
y2 would be the y-value of the second point,9. y1 would be the y-value of the first point, 7.
x2 would be the x-value of the second point, 1. x1 would be the x-value of the first point, 0.
Plugging those values in to the formula, we get m=(9-7)/(1-0)
Simplifying, we get m=2/1, which is m=2.
