Answer:
C.
Step-by-step explanation:
1) the slope-interception form of the given line is:
y=s*x+i, where s - the slope, i - interception;
according to the condition it is
y=1/8*x+i;
2) if to substitute the coordinates of the given point (-10;4) into the slope-interception form, then:
4=1/8* (-10)+i, ⇒ i=21/4;
the equation of the given line is:
y=1/8*x+21/4
3) according to the condition the given point with the coordinates (-6;w) belongs to the line. It means, it is possible to substitute its coordinates into the equation, then calculate the value of the 'w':
w=1/8*(-6)+21/4; ⇒ w=9/2.
Answer C. 9/2
Note: the suggested option is not the only.
Answer:
C. 9/2Step-by-step explanation:
Given points:
(-6, w) and (-10, 4)The slope is:
m = 1/8Value of w = ?Use slope formula and solve for w:
m = (y2 - y1)/(x2 - x1)1/8 = (4 - w)/(-10 - (-6))1/8 = (4 - w)/(-4)4 - w = -4/8w = 4 + 1/2w = 9/2Correct choice is C

A cookie recipe calls for 1.5 teaspoons of vanilla for one batch. How many teaspoons of vanilla would be needed for 2.5 batches of cookies?
Answer:
3.75
Step-by-step explanation:
it said 2.5 batches to you need to 1.5x2 = 3 15 divided by 2 = .75
3.75
3.75 teaspoons of vanilla will be needed for 2.5 batches of cookies. If it requires 1.5 teaspoons of vanilla for one batch.
The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.
Given,
It requires 1.5 teaspoons of vanilla for one batch which can be interpreted as 1 batches of cookies requires 1.5 teaspoons of vanilla.
1 batches----->1.5 teaspoons of vanilla
Using unitary method,
To calculate the number of teaspoons of vanilla needed for 2.5 batch is as follows:
1 batches----->1.5 teaspoons of vanilla
Multiply 2.5 both sides.
(1 batches)X 2.5----->(1.5 teaspoons of vanilla)X 2.5
2.5 batches----->3.75 teaspoons of vanilla
3.75 teaspoons of vanilla will be needed for 2.5 batches of cookies

Jasper decorates flower pots to sell in his shop.
HE knows that it takes 12 minutes to decorate a flower pot.
Jasper works from 9:30am until 12:50pm on Tuesday.
HE takes 20 minutes for a coffee break at 10:30am
How many flower pots does Jasper decorate on Tuesday?
Answer:
He works from 9:30am to 12:50pm.
He takes a brake at 10:30 for 20 mins.
Now the time he works will be
(12:50 - 9:30) - 20

HELP PLEASE!!!!!!!!!!!
A cone has a volume of 33 cubic inches. If a cylinder has the same height and the same radius as the cone, what is the volume of the cylinder?
Answer:
C
Step-by-step explanation:
Step-by-step explanation:
The volume of a cylinder = πr²h
= 33 cubic inches
The volume of a cone = ¹/3 πr²h
If the cylinder and come share the same radius and height then ‘πr²h’ part of the formulas is the same for both;
It means the difference in proportionality is ¹/3 (because even π is the same across board). The volume of the cone is therefore;
¹/3 (33)
= 11
= 11 cubic inches

Solve pls (correctly) brainliest if correct! I, lots of points!
Answer:
5
Step-by-step explanation:
First, find the equation of the line:
put it in the form y = mx + b where m is the slope and b is the y-intercept
You already have m = 2, so y = 2x + b.
Then, since you know (1, 3) is a solution so you can plug x = 1 and y = 3 into the equation to find out what b is.
3 = 2 * 1 + b
3 = 2 + b
1 = b
This means the equation of the line is y = 2x + 1.
Then, since you're trying to find out what y is when x = 2, you can plug in x = 2 into the equation:
y = 2 * 2 + 1
y = 4 + 1
y = 5
5 is the answer

Enter your answer, rounded to the nearest percent, in the box.
Answer:
It is 9%
Step-by-step explanation:
I took the test
Below, enter x If the graph of the given equation is symmetric with respect to the x-axis, y if it is symmetric with respect to the y axis, o (lower
case O) if it is symmetric with respect to the origin, and n (for None) if it has none of these three symmetries.
y=xt
y = x2 +1
y=x²+x
y = (1 + x2)3
Answer:
Step-by-step explanation:
You can tell by looking at the form of each equation.
y = tx
This is a straight line that passes through the origin, so it symmetric with respect to the origin.
y = x²+1
This is an up-opening parabola with vertex at (0,1), so it is symmetrical about the y-axis.
y = x²+x = (x+½)² - ¼
This is an up-opening parabola with vertex at (-½,-¼). Not symmetrical to either axis nor to the origin.
Can't tell what "y = (1 + x2)3" means. Which terms are exponents?

Ms. Jones bought a box with 8 packages of felt paper for her class. The total box of paper was priced at $40. If she buys the paper in single packages, the cost is $5.50 per package. How much does she save on 8 packages of paper by buying the whole box? Explain how you got your answer.
Answer:
$4
Step-by-step explanation:
To answer, we have to find the base unit of how much each package would cost out of a box. To do this, we divide the total amount of the box of paper by how many packages were inside:
40 / 8 = 5
So, each package costed Ms. Jones $5, while the single packages cost $5.50, so Ms. Jones saved $0.50 per package she bought, which if you multiply by 8, you get 4, so Ms. Jones saved a total of $4.
Hope this helps :)
