Answer:
y = 5x + 3 is a nonproportional relationship.
Step-by-step explanation:
We need to find the equation that represents a nonproportional relationship.
If y is directly proportional to x, it would mean that,
y ∝ x
y = kx
Option (b) shows the equation of a line i.e. y=mx+x, where m is slope and x is y-intercept.
Hence, we can say that option (b) represents a nonproportional relationship.
PLEASE SOMEONE!!HELP!! I need the answer right now
Answer:
m = -1, b = 5.
Step-by-step explanation:
We can find the slope, m, by plugging in our coordinates into the slope formula: [tex]\frac{y2-y1}{x2-x1} =\frac{2-7}{3-(-2)}=\frac{-5}{5}=-\frac{5}{5}=-\frac{1}{1}=-1[/tex]. That gives us the slope. Now we can fill that in the slope intercept formula: [tex]y=-1x+b[/tex]. We know one of the coordinates and the slope, which allows to find the y-intercept. We know that for every 1 unit down on the line, we move 1 unit right, and vice versa. Meaning we can just count down (or up in this case), so, (-2, 7), (-1, 6), (0, 5). Therefore, our y intercept is 5.
Felipe planted some seeds for a science project. One of his plants grew 6 1/2 inches in the first week, and then it grew 5 3/4 inches during the second week. How much did the plant grow during these two weeks? The answer should be written as a proper mixed number and should be simplified, if possible. *ill give brainliest*

AABC is dilated by a factor of 4 to produce AA'B'C'.
What is A'C, the length of AC after the dilation? What is the measure of ZA?
Answer:
A
Step-by-step explanation:
because the sky is blue
The length of AC after dilation will be 20. Then the measure of the angle ∠A' will be 37°.
We have given that,
AABC is dilated by a factor of 4 to produce AA'B'C'.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.
The triangle ΔABC is dilated by a factor of 4 to produce the triangle ΔA'B'C'.
Then the length of AC after dilation. We have
A'C' = scale factor x AC
A'C' = 4 x 5
A'C' = 20
Then the measure of the angle ∠A' will be
There is no effect of dilation on the angle.
∠A = ∠A' = 37°
Thus, the correct option is A.

In ATUV, the measure of _V=90°, the measure of ZT=66°, and TU = 93 feet. Find
the length of VT to the nearest tenth of a foot.
U
93
660
T
V
X
Answer:
VT = 37.8 ft
Step-by-step explanation:
Here, we want to get the measure of VT
We need the diagram of the triangle here
We can get this in the attachment
From the diagram, we have it that the hypotenuse is the length UT since it faces the right angle
VT does not face the given angle , nor the right angle; this mean VT is the adjacent
Mathematically, the trigonometric ratio that connects the adjacent to the hypotenuse is the cosine
Thus;
cos 66 = VT/UT
cos 66 = VT/93
VT = 93 * cos 66
VT = 37.83
To the nearest tenth of a foot, VT = 37.8 ft
The sculpture consists of four identical prisms. Jane says the surface area of the sculpture is 4 times the surface area of one prism. Which statement about jane's method is true?
Options:
A.) Jane should multiply volumes, not areas.
B.) Jane should also subtract the areas of six hidden surfaces.
C.) Jane should also add the areas of six hidden surfaces.
D.) Jane is correct.
Answer:
B.) Jane should also subtract the areas of six hidden surfaces.
Step-by-step explanation:
When three-dimensional solids are joined together to form a solid, some surfaces will be visible while others won't.
When calculating the surface areas of such shapes, we only consider the visible parts (i.e. the areas of the hidden parts will be subtracted from the total areas of the individual shapes).
Since the sculpture is not attached to this question, we can assume that there are 6 hidden surfaces (as suggested by the options). The areas of these 6 hidden surfaces must be subtracted to get the actual surface area.
Answer:
Jane should also subtract the areas of six hidden surfaces.

Solve Each system using elimination
Answer:
No solution
Step-by-step explanation:
The given system of equations are ,
3x - y = -1 y = 3x - 5 = y-3x = -5Adding both equations ,
=> 3x - y + y -3 x = -1-5
=> 0 = -6
Since we arrived at a contradiction the given pair of equations have No solution .

Mila buys a two liter soda bottle. She accidentally drops the soda bottle and spills 287 milliliters of soda. How much soda is left?
Answer:
1713 milliliters
Step-by-step explanation:
1 liter is 1000 milliliters, so 2 liters is equal to 2000 milliliters.
2000 mL - 287 mL = 1713 mL
So 1713 mL are left.

Answer:
x = 5.56
Step-by-step explanation:
Apply trigonometric function to find x
Reference angle = 46°
Hypotenuse = 8
Adjacent length = x
Apply CAH:
Cos 46 = Adj/Hyp
Cos 46 = x/8
8 × Cos 46 = x
5.55726696 = x
x = 5.56 (nearest hundredth)

What is the domain of the function y= (square root) x+4
Answer:
0 ≤ x ≤ ∞
Step-by-step explanation:
Square roots always need to be either equal to or greater than zero because it should be positive inside (unless we're working with imaginary numbers).
So the domain would be that x ≥ 0 (or the third choice ⇒ 0 ≤ x ≤ ∞).

Sean's party will cost $60 if he invites 12 guests. Which expression does NOT equal the amount that Sean will spend per party guest in dollars?
Options :
A) 12⟌60
B) 60 ÷ 12
C) 60⟌12
Answer:
C) 60⟌12
Step-by-step explanation:
Given that :
Total cost of inviting 12 guests to a party = $60
To obtain the cost per guest :
Total cost of invitation / number of guests
That is ; we divide the cost of inviting the guests by the number of guests invited
$60 / 12 = 12⟌60
The expression 60⟌12 is incorrect as this means 12 / $60

The curved surface area of a cylinder of height 28cm is 352sq.cm. Find the diameter of the base of the cylinder
Answer:
d = 4cm
Step-by-step explanation:
curved surface area (CSA) of cylinder = [tex]2\pi rh[/tex]
h = 28cm and CSA = 352[tex]cm^{2}[/tex]
[tex]2\pi rh[/tex] = 352
2 * [tex]\frac{22}{7}[/tex] * r * 28 = 352
[tex]r = \frac{352*7}{2*22*28}[/tex]
after calculating, you will get r = 2cm
so diameter = 4cm
