Answer:
The equation of the desired line is thus y = 4
Step-by-step explanation:
A line parallel to y = 5 is a horizontal line. The x-coordinate of every point on this line can take on any x-value; the y-coordinate is always 5.
The line that passes through the point (1, 4) has the constant y-coordinate 4, whereas x can take on any value.
The equation of the desired line is thus y = 4; this line passes through (1, 4) as required and is parallel to y = 5.

A store has a 25% off sale on coats. Marcy saved $18.75 on the coat she bought. What was the original price of the coat?
Answer:
$25
Step-by-step explanation:
18.75 is 75% of a value. You can easily find the answer by dividing 18.75 and 0.75.
When you have a problem like x*5=30, you divide 30/5 to get 6. Same here, x*0.75=18.75. Divide 18.75/0.75 to get the answer.
Answer:
25 dollars

Line segment AB is divided by point C in the ratio 1:2. Point A is at (-6, 6) and point C is at (2, 4). What are the coordinates of point B?
9514 1404 393
Answer:
B(10, 2)
Step-by-step explanation:
The division by point C means ...
B -C = 2(C -A)
B = 3C -2A . . . . . add C and simplify
B = 3(2, 4) -2(-6, 6) = (3·2 -2(-6), 3·4 -2(6)) . . . . fill in the coordinate values
B = (6+12, 12-12)
B = (18, 0)
There are 31 pink beads and 15 purple beads on Violet's necklace. What is the ratio of the number of beads to the number of pink beads?
Answer:
The ratio of number of purple beads to the number of pink beads is: 15:31
Step-by-step explanation:
Number of pink beads = 31
Number of Purple beads = 15
We need to find ratio of number of purple beads to the number of pink beads
So, The ratio of number of purple beads to the number of pink beads is:
Number of purple beads : Number of pink beads
15 : 31
Since it cannot be simplified further, So
The ratio of number of purple beads to the number of pink beads is: 15:31
On a trip to Spain Kelly brought a piece of jewellery that costs $50.75 she paid for with her credit card with charges of foreign transaction of a 4% fee The foreign transaction fee is
Answer:
Transaction fee is $1.95 approximately.
Step-by-step explanation:
Let the jewellrey costs $x before transaction fee.
So, we can set up equation for the given information as
x + 4% (x) = 50.75
Convert 4% to decimal by dividing it by 100.
x + 0.04 x=50.75
Simplify the left side of the equation.
1.04 x= 50.75
Divide both sides by 1.04
x= $48.7980..
So, transaction fee = 4% (48.7980)=$1.95 approximately.

Step-by-step explanation:
Lizard views: 4
Since Ferret has 9 times as much as Lizard views, you can multiply it by 9:
4 x 9 = 36 views
To find the difference, subtract Ferret views with Lizard views:
36 - 4 = 32 views

See question in image.
Please show workings .
Answer:
gradient = 9
Step-by-step explanation:
The gradient of the tangent at x = a is the derivative [tex]\frac{dy}{dx}[/tex]
Differentiate using the power rule on each term
[tex]\frac{d}{dx}[/tex] (a[tex]x^{n}[/tex] ) = na[tex]x^{n-1}[/tex] and [tex]\frac{d}{dx}[/tex] ( constant ) = 0
y = 2x² + 5x - 3
[tex]\frac{dy}{dx}[/tex] = 2.2[tex]x^{2-1}[/tex] + 5[tex]x^{1-1}[/tex] - 0
= 4x + 5
[tex]\frac{dy}{dx}[/tex] ( x = 1 ) = 4(1) + 5 = 4 + 5 = 9 ← gradient of tangent

Step-by-step explanation:
Given f(x) then the derivative f'(x) is
f'(x) = lim(h tends to 0 ) [tex]\frac{f(x+h)-f(x)}{h}[/tex]
= lim ( h to 0 ) [tex]\frac{4(x+h)^2-2-(4x^2-2)}{h}[/tex]
= lim ( h to 0 ) [tex]\frac{4(x+h)^2-2-4x^2+2}{h}[/tex]
= lim( h to 0 ) [tex]\frac{4x^2+8hx+4h^2-4x^2}{h}[/tex]
= lim( h to 0 ) [tex]\frac{8hx+4h^2}{h}[/tex]
= lim ( h to 0 ) [tex]\frac{4h(2x+h)}{h}[/tex] ← cancel h on numerator/ denominator
= lim ( h to 0 ) 4(2x + h) ← let h go to zero
f'(x) = 8x
Jacob's family traveled 2/7 of the distance to his grandfather's house on Saturday. They traveled 2/5 of the remaining distance on Sunday. What fraction of the total distance to his grandfather's house was traveled on Sunday?
Answer:
2/7
Step-by-step explanation:
on Saturday, the family drove 2/7 of the total distance
distance remaining after Saturday's trip = 1 - 2/ 7 = 5/7
On Sunday, they drove 2/5 of the remaining distance = [tex]\frac{2}{5} x \frac{5}{7} = \frac{2}{7}[/tex]

Use the information given to write an equation in standard form.
Slope is -2, and (4, 3) is on the line.
Answer:
[tex]2x+y=11[/tex]
Step-by-step explanation:
Standard form of an equation is written as [tex]ax+by=c[/tex] for some constants [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex].
Slope-intercept form is written as [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.
Plugging in all given values in the problem ([tex]m=-2[/tex], [tex]x=4[/tex], and [tex]y=3[/tex]), we can solve for [tex]b[/tex]:
[tex]3=-2(4)=b, \\b=11[/tex].
Therefore, our equation in slope-intercept form is:
[tex]y=-2x+11[/tex].
Rewriting in this in standard form, we get our answer:
[tex]\fbox{$2x+y=11$}[/tex]

30 points! Will mark brainliest. No random answer please.
Answer:
to determine whether the equation of the line parallel or perpendicular.we have to find there slope.
Step-by-step explanation:
2x+3y=153y=15-2x
y=15/3 -2x/3
y=5-2x/3
y=-2x/3 +5
so the cooficient tell us the slope of the line so it is -2/34x+6y=-48
6y=-48-4x
y=-4x/6 -48/6
y=-4x/6 -8
so the slope of this line is -4/6now to say two lines are parallel there slope should be the same
-2/3 ≠ -4/6
to say two line are perpendicular with one another the product of there slope should be -1
-2/3 * -4/6
=8/18
=4/9 which is different from -1
they are neither parallel nor perpendicular.7
Express 40 cm as a percentage of 5 m.

= 40cm / 500cm
= 4/50
= 2/25
= 8%
if this is the graph of f(x)=a^(x+h)+k, then: A. k>1
B. 0 1
Answer: B: 0 < a < 1
Step-by-step explanation:
The equation we have is:
f(x) = a^(x + h) + k.
k is the value at where we have the horizontal line. In this particular case, we can see that we have a horizontal line at y = -4, then we can conclude that:
k ≈ -4
a is the rate of growth. If a is positive and greater than 1, we would have an increasing function, for example with a = 2, k = 0 and h = 0 we have:
2^1 = 2
2^2 =4
2^3 = 8
This is an increasing function.
Now if a is greater than 0 and smaller than 1, we have a decreasing function (as seen in the graph). For example for a = 0.5, k = 0 and h = 0 we have:
0.5^1 = 0.5
0.5^2 = 0.25
0.5^3 = 0.125
This is a decreasing function.
Then the correct option is B, 0 < a < 1

its b

Lucas is making accessories for the soccer team. He uses 587.19 inches of fabric on headbands for 35 players and 2 coaches. He also uses 302.05 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answer: 24.5 inches
Step-by-step explanation:
Luca used 587.19 inches for 35 players and 2 coaches:
= 35 + 2
= 37 people.
The inches per person used for headband is:
= 587.19/37
= 15.87 inches
Luca then used 302.05 inches for just players who number 35 to make wristbands. Inches used per player is:
= 302.05/35
= 8.63 inches
Fabric used for each player is therefore:
= 15.87 + 8.63
= 24.5 inches
