Answer: second and fourth choices have infinitely many solutions
Step-by-step explanation:
When you combine the like terms in those two equations you end up with an "identity." Both sides of the equation are the same.
x - 1/3(3x) = 0 . 1/3 of 3x is 1x
x - x = 0 any number minus itself is 0
or add x to both sides x-x+x = 0 + x
x = x is an identity. An identity has infinite solutions.
3x + 2 - 1/3(3x) = 2 + 2x
3x + 2 -x = 2 + 2x
2x +2 = 2 + 2x . same thing! Infinite solutions.

if the value of c is negative, you would need zero pairs to model the factorization of the polynomial. the x-tiles on the board determine what the constants are in the factors. the product of these constants is equal to the value of c, so you would need positive tiles on one side of the x-squared tile and negative x-tiles on the other side to have opposite signs on the constants. opposite signs on the constants will result in a negative value for c when multiplying the factors.

Find the Average Rate of Change between the points given below.
(3, -7) and (5, 20)
Your answer:
Answers
13.5
Explanation:
The equation to find the slope (another word for the rate of change) of the line is (y2-y1)/(x2-x1) when the given points are (x1,y1) and (x2,y2).
When we plug in the given points, (3,-7) and (5,20) we can start solving.
(y2-y1)/(x2-x1)
(20-(-7))/(5-3)
Two negatives make a positive
= (20+7)/(5-3)

Calculate the height of a right circular cylinder with a surface area of 300 square inches and a radius of 5 inches. a. 2.45 inches c. 8.25 inches b. 4.55 inches d. 3.65 inches
Answers
Answer:
The height of the right circular cylinder is 4.55 inches ⇒ b
Step-by-step explanation:
The formula of the surface area of a right circular cylinder is
S.A = 2πrh + 2πr², where
r is its radiush is its height∵ The surface area of a right circular cylinder is 300 square inches
∴ S.A = 300 in.²
∵ Its radius is 5 inches
∴ r = 5 in.
∵ π = 3.14
→ Substitute them in the rule above
∵ 300 = 2(3.14)(5)(h) + 2(3.14)(5)²
∴ 300 = 31.4h + 157
→ Subtract 157 from both sides
∵ 300 - 157 = 31.4h + 157 - 157
∴ 143 = 31.4h
→ Divide both sides by 31.4
∵ 4.554140127 = h
∴ 4.55 = h
∴ The height of the right circular cylinder is 4.55 inches

solve for x
Answers
-7.2 -7.2
4x+0.8=5x
-4x -4x
0.8 = x
Hope this helps.
Answer:
x = 0.8
Step-by-step explanation:
We are given this equation:
4x+8=7.2+5x
And we want to solve it for x.
To solve equations, we need to isolate the variable (x) on one side, and the numbers on the other side.
First, we can clear the numbers from the right side by subtracting 7.2 from both sides.
4x + 8 = 7.2 + 5x
-7.2 -7.2
_______________
4x + 0.8 = 5x
Now, we can subtract 4x from both sides.
4x + 0.8 = 5x
-4x -4x
_______________
0.8 = x
This can be rewritten to be: x = 0.8
The value of x is 0.8

Write an equation of the line with a slope of -2/7 and a y-intercept of 5
Y=_____
Answers
Answer:
y= -2/7 +5
Step-by-step explanation:
The equation of the line with a slope of -2/7 and a y-intercept of 5 is y=-2/7 x+5.
Given that, slope (m) =-2/7 and y-intercept (c) =5.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The standard form of the slope intercept form is y=mx+c.
Put m=-2/7 and c=5 in y=mx+c, we get
y=-2/7 x+5
Therefore, the equation of the line with a slope of -2/7 and a y-intercept of 5 is y=-2/7 x+5.

6 Find the value of x' and each angle
Answers
The value of x=10 and m∠SOP=50° and m∠ROQ=50° .
When two straight lines intersect each other at a point then vertical angles are formed , there are two pair of vertically opposite angles and also , the vertically opposite angles are equal.
In the given question
m∠SOP = (5x)° ...(i)
and
m∠ROQ = (4x+10)° ...(ii)
and Since the angles m∠SOP and m∠ROQ are vertically opposite , they will be equal .
On equating we get ,
m∠SOP=m∠ROQ
Substituting the values from equation (i) and (ii) we get ,
5x=4x+10
5x-4x=10
x=10.
Substituting the value of x in equation (i) we get ,
m∠SOP = (5*10)° = 50°
Substituting the value of x in equation (ii) we get ,
m∠ROQ = (4*10+10)° = (40+10)° = 50°
Therefore , the value of x=10 and m∠SOP=50° and m∠ROQ=50° .

if θ is an angle in standard position and its terminal side passes through the point (-3,-4), find the exact value of \sin\thetasinθ in simplest radical form.
Answers
Here it is given,terminal side passes through the point.
I assume you want to find sinθ?
We know that sinθ = opposite/hypotenuse and that our coordinate point is in Quadrant II. If we construct a right triangle with a height of -4 units and a length of -3 units from right to left, then the side opposite of θ is -3 and the side adjacent to θ is -3. We need to determine the hypotenuse, which can easily be solved with the Pythagorean Theorem:
opp² + adj² = hyp²
-3²+ (-4)² = hyp²
9 + 16 = hyp²
25 = hyp²
5 = hyp
Therefore, sinθ=3/5.

x=11+2y-----(i)
Now,
i) -7x-2y= -13
or, -7(11+2y)-2y= -13
or, -77-14y-2y = -13
or -14y-2y = -13+77
or -16y = 64
or y =64÷(-16)
