Answer:
32
Step-by-step explanation:
f(x) = 7, so:
5 · 7 - 3= 35 - 3 = 32
Answer:
x = 2
Step-by-step explanation:
f(x) = 5x - 3
7 = 5x - 3
10 = 5x
2 = x
So, x = 2

[tex] \frac{3x}{x - 1} + 2 = \frac{3}{x - 1} [/tex]
[tex] \frac{3x}{x - 1} + \frac{2(x - 1) }{ x - 1} = \frac{3}{x - 1} [/tex]
[tex] \frac{3x}{x - 1} + \frac{2x - 2}{ x - 1} = \frac{3}{x - 1} [/tex]

Jenna works in an ice cream shop. When she starts her shift the tub of chocolate ice cream is 2/3 full. When she finishes her shift 6 1/2 h later,
there is only 1/6 of the tub left. What was the average hourly change in tub fullness?

Answer:
1/13
Step-by-step explanation:
Ice cream
starting = 2/3 full
After Jenna's shift = 1/6 of the tub
Total Time = 6.5hours
Amount of ice cream consumed = [tex]\frac{2}{3} - \frac{1}{6}[/tex]
= [tex]\frac{1}{2}[/tex] = 0.5
Rate per hour = amount of ice cream consumed -=/ total time
= 0.5/6.5 = 1/13 ice cream consumed per hour
Write a unit rate for the situation.
$12.50 for 5 ounces
$__ per ounce
Answer:
The correct answer is $2,50.
Step-by-step explanation:
The unit rate is what we use to determine the price of a single unit, when something is sold in a group, as in this case 5 ounces.
We have been told that $ 12.50 is the price for 5 ounces, but what we want to know is how much 1 ounce costs.
To determine this, what we must do is divide the total price by the quantity of ounces, in order to determine the unit price:
12.50 / 5 = 2.50
In this way we can verify that the unit price of 5 ounces is $ 2.50
1.If a number a is always less than another number b, which of the following expressions expresses their relationship?
A.a≤b
B.a≥b
C.a>b
D.a 0
D.x 9
Which of the following sentences is the word equivalent of the expression above?
A.The product between 3 and a number is no less than 9.
B.The product between 3 and a number is greater than 9.
C.The product between 3 and a number is no more than 9.
D.The product between 3 and a number is less than 9.
Answer:
Let's define the symbols:
x < y
means that x is strictly less than y.
x ≤ y
means that x is less than or equal to y.
(both of these signs can be in the other direction, take that in mind).
A) " a is always less than another number b"
Here we should have:
a < b.
a is always less than the other number b.
This is not in the options, so i suppose that there is a mistake in the question.
B) The expression "above" is not shown here, so i will just writhe the correspondent expression for each option, and you can see which one matches with the expression above.
a) "The product between 3 and a number is no less than 9"
3*n ≥ 9.
b) "The product between 3 and a number is greater than 9."
3*n > 9
c) "The product between 3 and a number is no more than 9"
3*n ≤ 9
d) "The product between 3 and a number is less than 9"
3*n < 9

Each square in the grid is a unit square with an area of 1 square unit. What is the area of the figure? square units
Answer:
The total area of the figure is: 16 square units
Step-by-step explanation:
The Area is basically a measure of how much space in square units there is inside an object.
Given that each square in the grid is a unit square with an area of 1 square unit.
The figure clearly shows that there are 14 complete squares and 4 half square units.
Thus, the total area of the figure is:
(1 × 14) + (1/2 × 4)
=14 + 2
= 16 square units
Therefore, the total area of the figure is: 16 square units

When two parallel lines are intersected by a transversal, the same-side exterior angles are supplementary. That means that their sum is 180.
Using that logic, if the two roads were parallel, then the sum of their same-side exterior angles will add up to 180. Yet their same-side exterior angles add up to 170 (130 + 40 = 170), hence they can't be parallel.
See the drawing attached below.
Using supplmenatry angles (two angles whose sum of measures add up to 180 or a straight line), we can say that:
m<DIE + m<HID = 18
40 + m<HID = 180
m<HID = 140
Similarly:
m<BHC + m<CHI = 180
130 + m<CHI = 180
m<CHI = 50
Using verticle angles therome, (when two lines intersect, the angles opposite to eachother are congruent, or have the same measure), we can say that:
m<DIE = m<GIH = 40
m<GIE = m<HID = 140
m<CHI = m<AHB = 50
m<BHC = m<AHI = 130

5/6 multiplied by 1/5
Show you work please
Answer:
The answer is 5/30
Step-by-step explanation:
The answer is 5/30 because when multiplying a fraction by a fraction you have to multiply the numerator by the numerator and the denominator by the denominator so if you multiply 5 by 1 you get 5 and when you multiply 6 by 5 you get 30 so the answer is 5/30

Answer:
A''(3/2, -3)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and rotation.
If a point A(x, y) is reflected over the x axis, the new point would be A'(x, -y).
If a point A(x, y) is dilated by a factor k, the new point would be A'(kx, ky).
Given that Trapezoid QUAD has vertices at Q(-4, 0), U(-2, 4), A(2, 4) and D(4, 0). If the trapezoid is reflected over the x-axis to create trapezoid Q'U'A'D', the vertices would be at Q'(-4, 0), U'(-2, -4), A'(2, -4) and D'(4, 0).
If trapezoid Q'U'A'D'is dilated by a factor of 3/4 respect to the origin to create trapezoid Q"U"A"D", the vertices would be at Q''(-3, 0), U''(-3/2, -3), A''(3/2, -3) and D''(3, 0)
