The values of the expression h(1), h(-7) and h(9) are 6, 50 and 62
Function and valuesAfter dividing one number by another, the modulo operation yields the remainder or signed remainder of the division.
Given the following modulus function shown below;
h(x)= |1 - 7x|, we are to find the following.
h(1)
h(-7)
h(9)
If x = 1, then;
h(x)= |1 - 7(1)|
h(1) = |1-7|
h(1) = |-6|
h(1) = 6
If x = -7, then;
h(-7)= |1 - 7(-7)|
h(-7) = |1--49)|
h(-7) = |1+49|
h(-7) = |50|
h(-7) = 50
If x = 9, then;
h(x)= |1 - 7(7)|
h(1) = |1-63|
h(1) = |-62|
h(1) = 62
This gives the equivalent values of the expression

Kevin and Randy Muise have a jar containing 69 coins, all of which are either quarters or nickels. The total value of the coins in the jar is $7.25 How many of each type of coin do they have?
Taking into account the definition of a system of linear equations, Kevin and Randy Muise have 19 quarters and 50 nickels.
System of linear equationsA system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. In this way, the values of the unknowns must be sought, with which when replacing, they must give the solution proposed in both equations.
Amount of quarters and nickelsIn this case, a system of linear equations must be proposed taking into account that
"q" is the amount of quarters."n" is the amount of nickels.You know that:
Kevin and Randy Muise have a jar containing 69 coins, all of which are either quarters or nickels. The total value of the coins in the jar is $7.25The system of equations to be solved is
q + n= 69
0.25q + 0.05n= 7.25
It is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, isolating the variable "q" from the first equation:
q= 69-n
Replacing this expression in the second equation:
0.25(69 - n) + 0.05n= 7.25
Solving:
0.25×69 - 0.25n + 0.05n= 7.25
17.25 - 0.25n + 0.05n= 7.25
- 0.25n + 0.05n= 7.25 - 17.25
-0.2n= -10
n= (-10)÷ (-0.2)
n= 50
Remembering that q= 69 -n, you get:
q=69 - 50
q= 19
Finally, there are 19 quarters and 50 nickels.

triangle ABC has vertices A(-2,-1), B (1,2) and C (2,-4), if triangle A'B'C' is a dilation of triangle ABC with a scale factor of 2,5 and center of dilation (0,0), give the coordinates of the vertices of triangle A'B'C'
After a dilation with a scale factor of 2.5 and center of dilation (0, 0), the coordinates of the vertices of triangle A'B'C' are A' (-5, -2.5), B' (2.5, 5), and C' (5, -10).
What is dilation?Dilation simply refers to a type of transformation which changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.
What is scale factor?A scale factor can be defined as the ratio of two (2) corresponding length of sides or diameter in two similar geometric figures such as triangles.
For the given coordinates, the dilation with a scale factor of 2.5 and center of dilation (0, 0) should be calculated as follows:
Point A (-2, -1) → Point A' (-2 × 2.5, -1 × 2.5) = Point A' (-5, -2.5).
Point B (1, 2) → Point B' (1 × 2.5, 2 × 2.5) = Point B' (2.5, 5).
Point C (2, -4) → Point C' (2 × 2.5, -4 × 2.5) = Point C' (5, -10).

13) Three adjacent angles are at a point. The first angle is represented by x, the second angle is 20° more than the
first, and the third angle is 20° more than the second angle. Find the measurements of all three angles.
Answer:
x=40 degrees
Step-by-step explanation:
adjacent angles add up to 180 degrees
First angle=x
second angles=x+20
third angle =x+40
add all and equate to 180 degrees i.e.
x+x+20+x+40=180
3x=180-60
x=40 degrees
x+20=40+20=60 degrees
x+40=40+40=80 degrees

What is fraction?A number that is stated mathematically as a quotient, where the numerator and denominator are divided. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator. A fraction is a number that is a component of a whole. By breaking a whole into a number of parts, it is evaluated. For instance, the symbol for half of a complete number or item is 12. The components of a whole or group of items are represented by fractions. A fraction consists of two components. The numerator is the figure at the top of the line. It details the number of equal portions that were taken from the total or collection.
Given Data
Length = 5[tex]\frac{5}{6}[/tex]
Length = [tex]\frac{35}{6}[/tex]
Straight section = 1[tex]\frac{1}{4}[/tex]

The equation of the line perpendicular to the given line and passing through (-3, 7) is; y = (-2/3)x + 5
What is the equation of the Line in slope intercept form?
We are given the equation of a line as; y = (3/2)x - 1
Now, the general form of equation of a line in slope intercept form is;
y = mx + c
where;
m is slope
c is y-intercept
Thus, for our given equation we have;
Slope; m = 3/2
y-intercept; c = -1
Now, for a line perpendicular to this, will have a slope of -1/(3/2) = -2/3
Thus, equation of the line perpendicular to the given line and passing through (-3, 7) is;
y - 7 = (-2/3)(x - (-3))
y - 7 = (-2/3)(x + 3)
y = 7 - 2 - (2/3)x

Answer:
Step-by-step explanation:
it's below
Answer:
(1, - 2 )
Step-by-step explanation:
7x - 3y = 13 → (1)
9x + 10y = - 11 → (2)
multiplying (1) by 10 and (2) by 3 and adding will eliminate y
70x - 30y = 130 → (3)
27x + 30y = - 33 → (4)
add (3) and (4) term by term to eliminate y
97x + 0 = 97
97x = 97 ( divide both sides by 97 )
x = 1
substitute x = 1 into either of the 2 equations and solve for y
substituting into (2)
9(1) + 10y = - 11
9 + 10y = - 11 ( subtract 9 from both sides )
10y = - 20 ( divide both sides by 10 )
y = - 2
solution is (1, - 2 )

Let the number of weeks be represented by w
Amount saved = $24
Amount needed = $850
Number of weeks = w.
This will be illustrated as:
24 + 40w = 850
Collect like terms
40w = 850 - 24
40w = 826
Divide
w = 826 / 40
w = 20.65 = 21 approximately
