Step-by-step explanation:
let the first number be x
let the second number be y
½ of the first number= ½x
Double the second; 2*y=2y
the sum... that is ½x+2y=14
The equation that could represent this description will be (1/2)x + 2y = 14.
How to convert the sentence into an expression?The act of converting a specified statement into an expression or equation is known as a sentence-to-equation transformation.
A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
Diego then says, If we take half of the first number (x) and double the second (y), the sum is 14. Then the equation is given below.
(1/2)x + 2y = 14

This zigzag crystal vase has a height of 12 inches. The cross sections parallel to the
base are always rectangles that are 5 inches wide by 4 inches long.
(a) If we assume the crystal itself has no thickness, what would be the volume of the
base?
A cubic inches
(b) The crystal is actually half an inch thick on each of the sides and on the bottom.
Approximately how much space is contained within the vase?
A cubic inches
The volume of the vase when the crystal itself has no thickness will be 240 inches³.
How to calculate the volume?The volume of the vase when the crystal itself has no thickness will be calculated thus:
V = Bh
V = (4in × 5in) × 12
V = 240 inches³
When the crystal is half an inch thick on each of the sides and on the bottom, the volume will be:

Write a function t(I) that determines the number of
toothpicks in any given level of the pyramid.
Using the table, we will see that the function is:
t(l) = 3*l
How to write the function?
Here we only have a table to work with, so we need to use that.
In the table, we can see the pairs:
t(1) = 3t(2) = 6t(3) = 9t(4) = 12So, in each new level, we just add 3 more toothpicks. Even more, we can see that the number of toothpicks is 3 times the value of l (the level) for all the cases in the table. So this is a linear function.
From that we can conclude that the function will be:
t(l) = 3*l

3-) Martha O'Brien made a deposit to her checking account at an ATM and received
$75 in cash. The checks deposited totaled $50 less than twice the currency amount,
and the total deposit was $25 more than the check amount. Determine the amounts
Martha deposited in checks and in currency as well as the total deposit.
Answer:
The amount Martha deposited in checks is $150
The amount Martha deposited in cash is $100
The total deposit is $175
Step-by-step explanation:
Since Total deposit (T) = currency (C) + coins + check (Ck) - cash received (Csh)
T = C + Ck - Csh. (1)
Given that cash received (Csh) = $75,coins = 0 and the checks deposited totaled $50 less than twice the currency amount. So,
Ck = 2C - $50 (2)
Also, total deposit was $25 more than the check amount. So,
T = Ck + $25 (3)
Substituting equation (2) into (1), we have
T = C + Ck - Csh
T = C + 2C - $50 - Csh
T = 3C - $50 - $75
T = 3C - $125 (4)
Substituting equation (2) into (3), we have
T = Ck + $25
T = 2C - $50 + $25
T = 2C - $25 (5)
Equating equations (4) and (5), we have
3C - $125 = 2C - $25
Collecting like terms, we have
3C - 2C = $125 - $25
C = $100
Substituting C into (2), we have
Ck = 2C - $50
Ck = 2($100) - $50
Ck = $200 - $50
Ck = $150
We now compute T
T = C + Ck - Csh.
T = $100 + $150 - $75.
T = $250 - $75
T = $175
So, the amount Martha deposited in checks is $150
The amount Martha deposited in cash is $100
The total deposit is $175

PLEASE HELP! WILL CROWN!! I need statements and reasons on DC and EF!!! plzzz
Answer:
DC⊥EF as the 2 angles in smallest triangle are 30 and 60 degrees, so the last one is 90 making Line DC perpendicular to Line EF.
Step-by-step explanation:
DC⊥EF means that Line DC is perpendicular (90 degrees) to EF.
To prove this, we can use the two angles of the small triangle created by the intersection of the triangles AEF and DCB.
The remaining angle of triangle AEF is 60, as all angles of triangles add up to 180 (so 180 - 12 = 60). This angle at F is shared with the little triangle.
Now we will get the angle at D using the triangle DCB. Since we are given two angles 90 and 60, angle D has to be 30.
So of our little triangle, we have angles 30 and 60, meaning the last one is 90 degrees and hence, DC⊥EF

Which of the following is NOT true about the following equation? y=−3
A) It is the equation of a horizontal line.
B) Its slope is zero.
C) It is perpendicular to the equation y=13x+2.
D) The line does not cross the x-axis.
Answer:
The statement which is NOT true about the equation y = -3 is
It is perpendicular to the equation y = 1/3x + 2 ⇒ C
Step-by-step explanation:
Let us revise the facts of the horizontal line:
The line is horizontal if all points on it have the same y-coordinatesThe horizontal line is parallel to the x-axisThe slope of the horizontal line is zeroThe equation of the horizontal line is y = b, where b is the y-coordinate of all points on the lineThe y-intercept of the horizontal line is (0, b)∵ The equation of the line is y = -3
→ Which means the value of y = -3 at any value of x
∴ The line is horizontal
∴ Its slope = 0
∵ The horizontal line is parallel to the x-axis
∴ The line does not intersect the x-axis
∴ The true statements are:
It is the equation of a horizontal lineIts slope is zeroThe line does not cross the x-axisThe statement which is NOT true about the equation y = -3 is
It is perpendicular to the equation y = 1/3x + 2
