f(x)=0 has at least two solutionsin the interval {2,9}
True

could be true or false
Answers
Function may return true or false.
What does "continuous function" mean?A continuous function is one in which a continuous variation of the input (i.e., a change without a jump) results in a continuous modification of the function's value. This indicates that there aren't any discontinuities, or sudden changes in value.
Here, the function f(x) is continuous.
It follows that if x = 2 then f(x) = 3,
if x = 5 then f(x) = -9,
if x = 7 then f(x) = -15,
if x = 9 then f(x) = -13.
There are at least two solutions in the interval {2,9} for the graph of the function cross x axis f(x) = 0, hence it is not provided.
Therefore, it may be true or false.

What are angles?When two rays are linked at their ends, they create an angle in geometry. The sides or arms of the angle are what are known as these rays.
When two lines meet at a point, an angle is created.
An "angle" is the measurement of the "opening" between these two rays. It is symbolized by the character. The circularity or rotation of an angle is often measured in degrees and radians.

Substituting 5 for y in #1 gives us the equation [tex]\frac{b^9}{b^5}=b^4[/tex]. This is the same as saying [tex]b^9^-^5=b^4[/tex], which is true.

Find the coordinate using the subtraction method
-2x+9y=-9
-3x+5y=12
Answers
The co-ordinates will be(x,y) by the given equation the co-ordinates (9,1).
How to co-ordinate using subtraction method?
The technique of subtracting one vector's coordinates from another vector's coordinates is known as vector subtraction.Addition is represented by travelling up the -axis and to the right on the -axis. Subtraction is represented by going left and down the -axis. Since we are travelling below, we can deduct from our coordinate point, and since we are heading rightward, we can add to it.So, the given equations are
-2x+9y=-9 ⇒ (i)
-3x+5y=12 ⇒ (ii)
(i) * 5 ⇒ -10x + 45y = -45
(ii) * 9 ⇒ -27x + 45y = 108
⇒ 17x = 153
x = 9
Now, substitute x=9 in equation (i)
-2(9) + 9y = -9
-18 + 9y = -9
9y = -9 + 18
y = 9/9
y = 1
Hence, the co-ordinates will be(x,y) by the given equation the co-ordinates (9,1).

Answers
Identify the points on the original figure.
Apply the transformation to each point to find the corresponding point on the image.
Connect the points on the image to form the image of the figure.
Here are the steps for each of the transformations you listed:
translation: (x, y) →(x+3, y-5)
To perform this transformation, we need to shift each point 3 units to the right and 5 units down. For example, if the original figure has a point at (1, 2), the image of that point would be at (1+3, 2-5) = (4, -3).
92.) translation: (x,y) →(x,y -2)
To perform this transformation, we need to shift each point 2 units down. For example, if the original figure has a point at (1, 2), the image of that point would be at (1, 2-2) = (1, 0).
reflection across x = -2
To reflect a figure across the line x = -2, we need to negate the y-coordinates of each point. For example, if the original figure has a point at (1, 2), the image of that point would be at (1, -2).
94.) reflect across y = 1
To reflect a figure across the line y = 1, we need to negate the x-coordinates of each point. For example, if the original figure has a point at (1, 2), the image of that point would be at (-1, 2).
rotation 180° about the origin
To rotate a figure 180° about the origin, we need to negate both the x- and y-coordinates of each point. For example, if the original figure has a point at (1, 2), the image of that point would be at (-1, -2).
rotation 90° counterclockwise about the origin
To rotate a figure 90° counterclockwise about the origin, we need to swap the x- and y-coordinates of each point and negate one of them. For example, if the original figure has a point at (1, 2), the image of that point would be at (-2, 1).
I hope this helps! If you provide the points on the original figure, I can help you graph the image for each of the transformations.
The image after the transformations of rotation, translation or reflection can be found by certain operation or rotation.
We can find how to know the image of certain figures after the given transformations are done.
91) Here it is translation.
x coordinates are shifted to right by 3 units and y coordinates are shifted to down by 5 units.
So the entire graph will be shifted to right by 3 units and down by 5 units.
92) Here, the translation is by not shifting the x coordinates and shifting the y coordinates 2 units to the down.
So the entire graph will be shifted to down by 2 units.
93) When a graph is reflected across x = -2, then the graph is moved horizontally such that the original figure and the image will be at the same distance from x = -2.
94) When a graph is reflected across y = 1, then the graph is moved vertically such that the original figure and the image will be at the same distance from y = 1.
95) When a graph is rotated about the origin 180°, if it is clockwise or anticlockwise, each of the coordinates (x, y) in the graph will become (-x, -y).
96) If the rotation is 90° counterclockwise about the origin, the coordinates (x, y) in the original graph becomes (-y, x).

What is the rational root theorem?The rational root theorem, also known as the rational root test, is an algebraic theorem that states that for a polynomial equation in one variable with integer coefficients to have a solution (root) that is a rational number, both the constant term (the term without a variable) and the leading coefficient (the coefficient of the highest power) must be divisible by the fraction's denominator.
An anXn+ an− 1xn − 1 + … + a1x1 + a0 = 0 is a polynomial equation in one variable (x), where a0, a1,..., and an are regular integers. Therefore, q must divide a and p must divide a0 for a polynomial equation to have a rational solution, p/q.
It is given in the question,
F(x)=2x^2-3x+7
Here, p is a 7-fold factor.
p, thus, might have a value of 1, -1, 7, or -7.
and q is a two-fold factor.
Thus, q might have a value of 1, -1, 2, or -2.

In this problem we have the case of recipe that requires 3 / 2 cups of flour in terms of certain number of measuring cups with an amount of 1 / 2 cups. The number of measuring cups (n) is equal to the total required by the recipe (M) divided by the amount of the measuring cup (m), both in cups. That is:
n = M / m
If we know that m = 1 / 2 cup and M = 3 / 2 cup, then the number of measuring cups is:

8m = 800cm
Remember that when multiplying by 100 you only have to add zeros.
For km, as it is bigger than m you have to divide by 1000, when dividing this time you only have to carry an imaginary point starting from right to left, the amount of zeros there are:

Answers
The slope is m = RISE / RUN, and the change in y is frequently referred to as "RISE."
Step-by-step explanation:[tex]5*x-6*y-(42)=0[/tex]
Tiger understands that this is a straight line equation. Typically, this equation is expressed as y=mx+b (or "y=mx+c" in the UK).
A straight line drawn using the Cartesian coordinate system has the formula "y=mx+b," where "y" denotes the vertical axis and "x" denotes the horizontal axis.
In this equation, y represents how high the line rises, x represents how far it travels along, m represents the slope or gradient, or how steep the line is, and b represents the Y-intercept, or the point at which the line crosses the Y axis.
The X, Y, and slope are collectively referred to as the line properties. We will now plot the line 5x-6y-42 = 0 and determine its characteristics.
x = 0 the value of y is 7/-1 so this line "cuts" the y axis at y=-7.00000
y-intercept = 42/-6 = 7/-1 = -7.00000
y = 0 the value of x is 42/5 Our line therefore "cuts" the x axis at x= 8.40000
x-intercept = 42/5 = 8.40000
Slope = 1.667/2.000 = 0.833 x-intercept = 42/5 = 8.40000 y-intercept = 42/-6 = 7/-1 = -7.00000To learn more about 5x+6y=-42 refer to:
