Solve for the slope (rate of change) of the given table.
Answer:
3
Step-by-step explanation:
The slope is found by using two points:
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
We can just plug in the first two points:
[tex]\frac{19-13}{4-2}=\frac{6}{2} =3[/tex]
‘That’s the slope! :)
In the past month, Brian rented 5 video games and 1 DVD. The rental price for each video game was $2.60. The rental price for the DVD was $4.30. What is the
total amount that Brian spent on video game and DVD rentals in the past month?
Pls help!
Answer:
$17.30
Step-by-step explanation:
So each video game is $2.60 and Brian rented 5 of them.
5 * 2.60 = 13
He spent $13 on just the video games. Now, he also rented 1 DVD, priced at $4.30.
13 + 4.30 = 17.30
Brian spent a total of $17.30 on rentals in the past month.

c = 20

с
b = 16
The length of the missing side of the right triangle is a =
The third side of the triangle is 12 units and the measure of the angle θ is 37°.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
The third side of the triangle 'a' is calculated by Pythagoras' theorem. Then we have
c² = a² + b²
20² = a² + 16²
400 = a² + 256
a² = 400 - 256
a² = 144
a = 12
Then the value of the angle θ is calculated as,
sin θ = 12 / 20
sin θ = 3 / 5
sin θ = sin 37°
θ = 37°
The third side of the triangle is 12 units and the measure of the angle θ is 37°.

Answer:
[tex] {27.5}^{2} [/tex]
Step-by-step explanation:
[tex]area \: of \: a \: triangle = \frac{1}{2} bh [/tex]
to make the method easy we can divide the fingure into 2 parts
first part
[tex] \frac{1}{2} \times b \times h \\ \\ \frac{1}{2} \times 8 \times 5[/tex]
(because 3+2=5)
[tex] \frac{1}{2} \times 8 \times 5 = {20}^{2} [/tex]
second part
[tex] \frac{1}{2} \times 5 \times 3 = {7.5}^{2} [/tex]
add the 2 areas

Can someone please do this for me?
Answer:
64°
Step-by-step explanation:
So supplement angles are equal to 180, so first our two angles added together will be 180:
x + x = 180
Now one of these angles is 6 greater than half:
x + (x/2 + 6) = 180
Then we will solve for x:
x + (x/2 + 6) = 180
x + x/2 + 6 = 180
x + x/2 = 174
[tex]\frac{3}{2}[/tex]x = 174
x = 116
Plug it back in:
x + (x/2 + 6) = 180
/\
x/2 + 6
(116)/2 + 6
64
To check:
116 + 64 = 180 ✓

Find the slope of the line that passes through (7, 10) and (5, 13).
Answer:
it is -3/2
Step-by-step explanation:
use rise/run or y/x to find slope. Start with the lower x value, so the run (movement on the x axis) is 2 so plug that in, rise/2. Fine the rise whish is -3, plug that in and you get -3/2
Put the following equation of a line into slope-intercept form, simplifying all fractions.
2x+2y=-4
Answer:
y = -x-2
Step-by-step explanation:
slope-intercept form: y=mx+c
2x+2y=-4
2y= -2x -4
y= -x -2
slope: -1
intercept: -2
Can anyone please help me solve for x, y, and z?
Answer:
z= 3
y = 105
x= 90
Step-by-step explanation:
y-12 = 90+z

y = z + 102
z + 102 - 18 + z = 90
2z = 90 - 84

0.25 < x < 2
Step-by-step explanation:
The quadratic can be factored as ...
4x^2 -9x +2 < 0
(4x -1)(x -2) < 0
The factors are zero for x = 1/4 and x = 2. The product of the factors will be negative, satisfying the inequality, for values of x that make one factor positive and the other one negative. Those values of x are between x=1/4 and x=2.
The solution is 1/4 < x < 2.
The graph on the number line has open circles at x=1/4 and x=2, and is shaded between those values.
_____
Additional comment
The circles on the graph are open because those x-values are not part of the solution set.

A store buys a TV for $100. They sell it for a 70% mark-up. What is the new cost of the TV?
Answer:
170
Step-by-step explanation:
Since the TV is worth $100 initially but has a 70% markup, it means they increased the price by the percent markup
100 x .70 = 70
100 + 70 = $170
The new cost of the TV sold at this store is equal to $170.
Given the following data:
Cost price = $100Markup = 70%To determine the new cost of the TV sold at this store:
How to calculate markup price.We would calculate the markup price by multiplying the cost price by the markup.
[tex]Markup\;price = \frac{70}{100} \times 100\\\\Markup\;price = 0.7\times 100[/tex]
Markup price = $70
Now, we can find the new cost of the TV:
[tex]New\;cost = Markup\;price + Cost\;price\\\\Total\;cost = 70 + 100[/tex]
Total cost = $170.

Use the graph to determine the following.
a. the function's domain
b. the function's range
c. the x-intercepts, if any
d. the y-intercept, if any
e. the function values, f(1) and f(4).
Assume that the graph of the function
continues its trend beyond the displayed coordinate grid.
From the graph of function,
a. Domain = (-∞, ∞)
b. Range = [-2, -∞)
c. x-intercept = NA
d. y-intercept = (0, -4)
e. f(1) = -3 and f(4) = -4
What is domain of a function?"It is a set of points which for which the function is well defined."
What is the range of the function?"It is the set of all possible output values."
What is intercept?"It is a point at which the graph of the function intersects the x-axis or y-axis."
For given example,
From the graph of a function we can observe that, function takes all values of x
So, domain = (-∞, ∞)
The value of the function starts from -2 and it tends towards -∞.
So, Range of f(x) = [-2, -∞)
From the graph of a function we can observe that the graph of a function does not intersect the x-axis.
So, for given function has no x-intercept.
The graph of the function intersects y-axis at (0, -4).
So, y-intercept = (0,-4)
We need to find the value of f(1) and f(4)
From the graph,
for x = 1,
⇒ f(1) = -3
for x = 4,
⇒ f(4) = -4
Therefore, from the graph of function,
a. Domain = (-∞, ∞)
b. Range = [-2, -∞)
c. x-intercept = NA
d. y-intercept = (0, -4)
e. f(1) = -3 and f(4) = -4

2. A coupon has been issued for crackers at the local grocery store. The crackers originally retail for $3.79 a box and the coupon is good for 10% off the price marked on the shelf. When you arrive at the store the crackers are already marked down by 15%. What is the price you will pay for the box of crackers?
Answer:
$3.54
Step-by-step explanation:
$3.79-25% (because you add the 15% + 10%)
which is $3.54
Answer:
$2.90
Step-by-step explanation:
start with original price
$3.79
marked down 15%
3.79 × .15 = .5685 or .57
3.79 - .57 = 3.22 price on shelf
minus 10% coupon
3.22 × .1 = .322 or .32
$3.22 - .32 = $2.90

Answer:
a) x = 3
b) 4x
c ) 9x - x
Step-by-step explanation:
a)2x + 4(x -1) = 2 + 4x
2x + 4x - 4 = 2 + 4x
2x[ + 4x [- 4 = 2 [+ 4x
2x + 4x - 4x = 2+4
2x = 6
(Simply both sides by 2)
X = 3
b)25 - x = 15 - (3x + 10)
25 - x = 15 - 3x + 10
25[ - x = [15[ - 3x [+ 10
25 - 15 - 10 = 3x + x
0 = 4x
4x
c)4x = 2x + 2x + 5 (x - x)
4x = 2x + 2x + 5x - 5x
