Answer:
the y-intercept is 22 spaces higher.
Step-by-step explanation:
I don't know, what special operations you want to express with 3(5)x.
as it is written this simply means
3×5×x
no exponents or other special things are visible.
but it should not matter.
whatever is the first function is unchanged the first part of the second function.
so, the only difference is the "+ 22" part.
and that simply means that all y values (the functional result values) are increased by 22.
you know that "f(x) =" has the same meaning as "y =".
and with that also the y-intercept (the y value when x = 0, and therefore the point, where the curve intersects the y-axis) is increased by 22 spaces.
does someone mind helping me with this problem? Thank you!

∠A + ∠B + ∠C = 180°
Here the value of ∠B and C is given below...we need to find the value of ∠A ....
a + 120° + 40° = 180°
a + 160° = 180°

What is the equation of the line that is perpendicular to the line y = 4x + 3 and
passes through the point (4, -1)?
O A y-¹-x-2
O B. y=-x+1
OC. y= 4x-17
O D. y=-1x
Step-by-step explanation:
perpendicular means at a 90° angle.
the slope (incline) of a line is always the factor of x. in our case of the original line 4.
it is the ratio of
y change / x change
so, the "4" is actually 4/1.
a perpendicular slope is just turning y/x upside down and flips the sign.
so, the slope of our new line is
-1/4
and the new line looks like
y = -1/4 x + b
to get b we simply use the point coordinates for x and y :
-1 = -1/4 × 4 + b
-1 = -1 + b
so, b = 0
the final equation for our new line is
y = -1/4 x or -x/4
so I guess you left something out at the answer options, and the answer would be D.
Gabriel is raising money for a school trip by selling lollipops and bags of chips. The price of each lollipop is $1 and the price of each bag of chips is $1.50. Yesterday Gabriel made $30 from selling a total of 26 lollipops and bags of chips. Graphically solve a system of equations in order to determine the number of lollipops sold, x,x, and the number of bags of chips sold, yy.
Answer:
[tex]x + \frac{3}{2} y = 30[/tex]
and
[tex]x + y = 26[/tex]
Answer:
18 lollipops8 bags of chipsStep-by-step explanation:
The equations we want to graph are one for the revenue, and one for the number of items sold.
__
revenueThe revenue from each lollipop is $1, so the revenue in dollars from selling x of them is 1·x = x. The revenue from each bag of chips is $1.50, so the revenue from selling y of them is 1.50·y = 1.5y. The total revenue from selling x lollipops and y bags of chips is ...
x +1.5y = 30 . . . . . dollars
__
item countThe total number of items sold is ...
x + y = 26
__
solutionThe graph shows the solution to these two equations is ...
(x, y) = (18, 8)
The number of lollipops sold is 18; the number of bags of chips sold is 8.

n a large high school, 37% of the teachers believe that five minutes is not enough time for students to change classes. However, 89% of the students believe that five minutes is not enough time for students to change classes. Let p hat Subscript Upper F and p hat Subscript Upper S be the sample proportions of teachers and students, respectively, who believe that five minutes is not enough time for students to change classes. Suppose 28 teachers and 100 students are selected at random and asked their opinion on the amount of time students have to change class. Which of the following is the correct shape and justification of the sampling distribution of p hat Subscript Upper F Baseline minus p hat Subscript s ?
The difference (faculty-student) in the sample proportions of those who believe that five minutes is not enough time for students to change classes typically varies about 0.096 from the true difference in proportions. Option D is correct.
What is the standard deviation?It is a measurement of statistical data dispersion. The degree to which the value varies is known as standard deviation.
The standard deviation of the sampling distribution is found as;
[tex]\rm \sigma_F-\sigma_s= \sqrt{\frac{0.37 \times (1-0.37)}{28}+\frac{0.89 \times (1-0.89)}{100} } \\\\ \sigma_F-\sigma_s=0.096[/tex]
The difference in the sample proportions of those who think five minutes is not enough time for students to switch classrooms generally differs by roughly 0.096 from the actual difference in proportions.
Hence option D is correct.

If a and b are negative real numbers and
a
Answer:
[tex]a^{2} > b^{2}[/tex]
Step-by-step explanation:
if a<b<0
then the absolute value for a is greater than that of b
as a results, the square of a should be greater than that of b
Step-by-step explanation:
remember,
e.g. -12 < -8
or -741 < -589
but then the corresponding positive numbers
12 > 8
741 > 589
so, if we have 2 negative numbers a, b with a < b, then
a² > b²
because the square is always delivering a positive number.
and as positive a > positive b, then so is a² > b².
3.) What is the measure of angle a in the triangle below?
a

40°
Step-by-step explanation:
∠ACB = ∠DCE ( vertically opposite angle )
Now...
a + 90° + 50° = 180° ( the sum of interior angle of triangle is 180° )
a + 140° = 180°

Step-by-step explanation:
so you have sum of 9 which is 9
sum less than 5 which is 4,3,2,1
And a sum greater than 9 but less than 11 so 10
10 +9 is greater than 11
10 +4, 10 + 3, 10 +2, 10 + 1 would work too
9+5, 9+4,9+3, 9+2 would work as well the only one who wouldn’t is 9+1 but you have more that work than don’t

"What is the cost of an orange?" Sue asked the store clerk. "If you buy two oranges and give me a dime, I will give you forty cents change from two dollars, " replied the store clerk. How much does one orange cost?
From the calculation done below, it can be seen that the cost of one orange is 85 cents.
How do we determine the cost of a product?The cost of one orange can be determined as follows:
One dime = 10 cents
2 dollars = 200 cents
Total amount given by Sue to the store clerk = One dime + 2 dollars = 10 cents + 200 cents = 210 cents
Cost of two oranges = Total amount given by Sue to the store clerk –

Find the slope intercept form of 24 = 4y - 8x
Answer:
y = 2x + 6
Step-by-step explanation:
The slope-intercept form is y = mx + c ,
where m is the slope and c is the y-intercept.
So we have to make our equation look similar to the one above.
We can do this by isolating y, by adding 8x to both sides:
4y = 24 + 8x
Now divide both sides of the equation by 4:
y = 6 + 2x
∴ y = 2x + 6
This equation is of the same form as the one given above, so this will be our solution.
Answer:
y=2x+6
Step-by-step explanation:
Step 1) Add 8x to each side of the equation.
24=4y-8x
+8x +8x
8x+24=4y
Step 2) Divide all terms by 4 to isolate y
2x+6=y
Optional: Flip equation

Suppose that you increase the height of this cylinder by 10 cm. By how much does the volume increase?
radius = 5 cm, height = 7 cm
Volume is a three-dimensional scalar quantity. The increase in the volume of the cylinder is 785.398 cm³.
What is volume?
A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
Given the radius of the cylinder is 5 cm, while the height of the cylinder is 7 cm, therefore, the volume of the cylinder,
Volume = πR² × H = π×(5²)×7 = 175π cm³
Now, if the height of the cylinder is increased by 10, then the height of the cylinder will become 17 cm(10+7), therefore, the volume of the cylinder will be,
Volume = πR² × H = π×(5²)×17 = 425π cm³
Now, the increase in the volume will be,
Increase in the volume = 425π - 175π = 250π = 785.398 cm³
Hence, the increase in the volume of the cylinder is 785.398 cm³.
