Determine the value of y, if x is-9.
Answer:
[tex]y=82[/tex]
Step-by-step explanation:
We know the value of x is -9 so we can plug it in as -9.
[tex]y=x^2+1\\y=(-9)^2+1\\y=81+1\\y=82[/tex]
Answer:
82=y
Step-by-step explanation:
-9 x -9 = 81
81 + 1 = 82

5/x=-9
find the variable
Answer:
x = -5/9
Step-by-step explanation:
5/x = -9
multiply by x on both sides
5 = -9/x
multiply by 1/-9 on both sides
-1/9*5 = -1/9 *-9/x
-5/9 = x

2x + 8 = 2(x + 4)
Answer:
All real numbers are solutions
Step-by-step explanation:
2x + 8 = 2(x + 4)
~Simplify right side
2x + 8 = 2x + 8
~Subtract 8 to both sides
2x = 2x
~Divide 2 to both sides
0 = 0
Best of Luck!
Answer: the answer is infinite
Step-by-step explanation: so first you need to distribute the 2 into the () and you would get 2x+8 and since it is the same on both sides it cancles eachother out therefore there is infinite answers
Tucker got in his car and started driving toward his grandmother's house. After driving for 1 hour and 30 minutes, Tucker took a break for 40 minutes to have a snack. Then Tucker drove 1 hour and 40 minutes and finally arrived at his grandmother's house at 6:05 P.M. What time did Tucker start driving?
Answer: He started driving at 2:15 P.M.
Step-by-step explanation:
Answer:
3:05 P.M
Step-by-step explanation:
6:05 - 1 hour and 30 min = 5:25
5:25-40 minutes = 4:45

Answer:
The slope is -(1/3)
Step-by-step explanation:
For every 3rd step, the y-value decreases by 1 and the line intersects the y-axis in (0,1).
This observation yields the following equation for your line:
f(x) = y = -(1/3)x + 1
Therefore, the slope is -(1/3).

What is the solution to 5x-2<13
Answer:
x<3
Step-by-step explanation:
Step 1: Add 2 to both sides.
5x−2+2<13+2
5x<15
Step 2: Divide both sides by 5.
5x/5 < 15/5
x<3
Write the equation of the line that passes through the points (8, 14) and (-2,-16) in slope-intercept form.
Answer:
y = 3x - 10
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (8, 14) and (x₂, y₂ ) = (- 2, - 16)
m = [tex]\frac{-16-14}{-2-8}[/tex] = [tex]\frac{-30}{-10}[/tex] = 3 , then
y = 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, 14 ) , then
14 = 24 + c ⇒ c = 14 - 24 = - 10
y = 3x - 10 ← equation of line
An isosceles triangle includes two 72°
angles. Which equation could be used to
find the measure of the third angle?
A X + 72 = 180
B X = 180 - 72
C 72-X= 180
D 180 - 2(72) = X
I don't understand the options but I will explain it to u!
Step-by-step explanation:
An Isosceles triangle has two equal sides that means , In this question it is given that there are two 72°angles so,
72+72+x =180
(Transpose)
x = 180-(72+72)
x = 180-(144)
Therefore, x= 36
In an isosceles triangle, two sides are equal and their opposite angles are also equal. Then the correct option is D.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
An isosceles triangle includes two 72° angles.
In an isosceles triangle, two sides are equal and their opposite angles are also equal.
And the sum of the angles of the triangle is 180°.
Let the third angle be x. Then we have
72° + 72° + x = 180°
180° - 2(72°) = x
Thus, the correct option is D.

subtract (2y + 3x-x²) from (5x²-y2-2x)
Answer:
6x² - 5x - y² - 2y
Step-by-step explanation:
We have
5x² - y² - 2x - (2y + 3x - x² ) ← distribute parenthesis by - 1
= 5x² - y² - 2x - 2y - 3x + x² ← collect like terms
