Answer:
[tex]x=-\dfrac{41}{14}[/tex]
Step-by-step explanation:
[tex]7(2x+6)=1[/tex]
Expand parentheses:
[tex]14x+42=1[/tex]
Subtract 42 from both sides:
[tex]14x=-41[/tex]
Divide both sides by 14:
[tex]x=-\dfrac{41}{14}[/tex]
Hope this helps!
Answer:
x = -41/14
Step-by-step explanation:
7(2x+6)=1
Distribute
14x +42 =1
Subtract 42 from each side
14x+42-42 = 1-42
14x = -41
Divide each side by 14
14x/14 = -41/14
x = -41/14

Select all polynomials that are divisible by (x + 3).
Choose all answers that apply:
© A(x)= x3 + 4x2 – 9
® B(x) = x3 – 22 – 18
© C(x) = x3 – 6x – 9
© D(x) = x3 + 3x +3
Answer:
x³+4x²-9
Step-by-step explanation:
x+3=0
x=-3
put x=-3 into x³+4x²-9, if it is equal to zero then it is dividsble
so, (-3)³+4(-3)-9=0

The polynomial A(x) is divisible by (x+3).
What is factor?
A factor is a number or expression that divides another number or expression leaving no remainder.
What is factor theorem?If p(x) be the polynomial, then p(x) is divisible by q if q is the factor of p(x).
According to the given question
we have different polynomials
[tex]A(x) = x^{3} +4x^{2} -9[/tex]
When we divide A(x) by (x+3) we get remainder 0.
⇒ (x+3) is a factor of A(x).
Hence, the polynomial A(x) is divisible by (x+3).
[tex]B(x) = x^{3} -22 -18[/tex]
⇒ [tex]B(x) = x^{3} -30[/tex]
When we divide B(x) by (x+3) we get remainder -57.
⇒ (x+3) is not a factor of B(x)
Hence, the polynomial B(x) is not divisible by (x + 3).
[tex]C(x) =x^{3} -6x -9[/tex]
By dividing C(x) by (x +3) we get remainder -18
⇒ (x+3) is not a factor of C(x).
Hence, C(x) is not divisible by (x+3).
[tex]D(x) = x^{3} + 3x + 3[/tex]
By dividing D(x) by (x+3), we get remainder -33.
⇒ (x+3) is not a factor of D(x).
Hence, D(x) is not divisible by (x+3).
Thus, the polynomial A(x) is divisible by (x+3).

The human body has a normal temperature of 98.6°F. Doctors will get worried if a sick patient has a temperature that
varies from the normal by more than 3°F. Create an absolute value inequality and solve it to determine what body
temperatures would be considered unhealthy.
Answer: | t- 98.6 | ≤ 3
Temperatures less than 95.6 and higher than 101.6 will be considered unhealthy.
Step-by-step explanation:
Hi, to answer this question we have to write an inequality
.
| t- 98.6 | ≤ 3
Where t is the body temperature.
The absolute value inequality has 2 solutions:
1st solution
t-98.6≤ 3
t ≤ 3+98.6
t≤ 101.6
2nd solution
-(t-98.6) ≤ 3
-t+98.6 ≤ 3
98.6-3 ≤ t
95.6≤ t
Both:
95.6≤ t ≤ 101.6
Temperatures less than 95.6 and higher than 101.6 will be considered unhealthy.

does a definite offer must include enough information to reasonably infer the terms?
Answer: Yes, it must.
Step-by-step explanation:
By definition, a definite offer must offer enough information to the offerer to understand the offer. In other words, the terms must be clear enough for the offerer to understand the offer and decide if he/she accepts the offer or not.
So yes, a definite offer must include enough information to infer the terms, if not, this is not a definite offer.

In the picture above, parallel lines p and q are cut by transversal line t. If the measure of angle 1 is 11x+7 and the measure of angle 8 is x+17, then x is equal to and the measure of angle 1 is degrees. The measure of angle 8 is degrees. *please hurry*
Answer:
x = 13
Angle 1 = 150 degrees
Angle 8 = 30 degrees
Step-by-step explanation:
11x + 7 + x + 17 = 180
12x + 24 = 180
12x = 180 - 24
12x = 156
x = 13
11(13) + 7 = 150
(13) + 17 = 30
The co-interior angles are solved and x = 13
The measure of angle 1 = 150°
The measure of angle 1 = 30°
Given data:
Angles in parallel lines are angles that are created when two parallel lines are intersected by another line.
Alternate angles are equal
Corresponding angles are equal
Co-interior angles add up to 180°
The angles 1 and 8 are co-interior angles.
So, 11x + 7 + x + 17 = 180
12x + 24 = 180
12x = 180 - 24
12x = 156
x = 13
So, the measure of angle 1 = 11(13) + 7 = 150°
The measure of angle 8 = (13) + 17 = 30°
Hence , the parallel lines are solved.

Step-by-step explanation:
We can substitute y for x+3 in the second equation
4x + x + 3 = 18
5x = 15
x=3
Plug x back into the equation
y = 3 + 3
y = 6

y = x + 3
4x + y = 18
4x + (x + 3) = 18
5x = 18 - 3
5x = 15
x = 3
y = x + 3
y = 3 + 3

The graph of a line in the xy - plane passes through the point (8,6) and
crosses the y axis at the point(0, -18). What is the x-intercept of the
line?
Answer:
(6,0)
Step-by-step explanation:
First, let's find the line. We can do that by using the slope-intercept form of a line which is y = mx + b where m and b are the slope and y-intercept respectively. We know b = -18 and we can find m by doing (-18 - 6) / (0 - 8) = -24 / -8 = 3. Therefore, the equation of the line is y = 3x - 18. To find the x-intercept, we'll set y equal to 0. We get 0 = 3x - 18 → 3x = 18 → x = 6. Therefore, the x-intercept is (6,0). Hope this helps!
