Suppose the goal is to raise $600. One equation relating the calendar and poster sales to the $600 goal is 3c + 2p= 600. Suppose the company donating the calendars and posters said they would provide a total of $250 items.
Answers
Answer:
100 calendars and 150 postersStep-by-step explanation:
Note it seem the "$" shouldn't be in front of 250 as it is the numbe of itemsa) The second equation is
c + p = 250b) The graph of both equations is attached
The intersection point of the lines is (100, 150)
It indicates 100 calendars and 150 posters to be donated to meet both of targets $600 and 250 items.
Answer:
Given equation:
[tex]3c+2p=600[/tex]
where:
c = number of calendarsp = number of postersPart (a)If the company donating the calendars and posters said they would provide a total of 250 items then:
[tex]c+p=250[/tex]
Part (b)To graph:
Rewrite both equations to make p the subjectFind the c-interceptFind the p-interceptConnect the two points with a straight line[tex]3c+2p=600 \implies p=300-\dfrac{3}{2}c[/tex]
[tex]\textsf{x-intercept}: \quad 300-\dfrac{3}{2}c=0 \implies c=200 \implies (200,0)[/tex]
[tex]\textsf{y-intercept}: \quad 300-\dfrac{3}{2}(0)=300 \implies (0,300)[/tex]
[tex]c+p=250 \implies p=250-c[/tex]
[tex]\textsf{x-intercept}: \quad 250-c=0 \implies c=250 \implies (250,0)[/tex]
[tex]\textsf{y-intercept}: \quad 250-0=250 \implies (0,250)[/tex]
Point of intersection (equate equations):
[tex]\begin{aligned}300-\dfrac{3}{2}c &=250-c\\50 & =\dfrac{1}{2}c\\ c & =100\end{aligned}[/tex]
[tex]p=250-100=150[/tex]
[tex]\implies \left(100,150}\right)[/tex]
The point of intersection tells us that they need to sell 100 calendars and 150 posters to reach their goal of raising $600. Therefore, the company needs to provide 100 calendars and 150 posters (or 250 items in the ratio of calendars to posters of 2 : 3).

The transformation (x, y) to (x+4, y-3) is preformed on the line segment AB. The image is the line segment A'B' where point A' = (3, -3) and point B' = (5, -3). What are the coordinates of A and B in line segment AB?
A) A = (-1, 6), B = (1, -6)
B) A = (-1, 0), B = (1, 0)
C) A = (7, 6), B = (9, -6)
D) A = (7, 0), B = (9, 0)
Answers
Answer:
B) A = (-1, 0), B = (1, 0)
Step-by-step explanation:
If the transformation of AB to A'B' is (x+4, y-3),
then the transformation of A'B to AB is the reverse: (x-4, y+3)
Given
A' = (3, -3) → A = (3-4, -3+3) = (-1, 0)
B' = (5, -3) → B = (5-4, -3+3) = (1, 0)
Therefore:
A = (-1, 0), B = (1, 0)

43. Find an equation of the tangent line to the curve [tex]y=10^{x}[/tex] at the point (1,10)
Answers
Answer:
23x-y=13
Step-by-step explanation:
we need to find the derivative with respect to x
In(y) =In(10^x)
In(y)=xIn(10)
now we have to take the derivative with respect to x
Therefore, y'=yIn(10)
where y'=10^xIn(10), Chain rule!
note: First derivative function always give us the gradient value when x value is substituted in
Therefore, at x=1, our gradient will be m= 10^1In(10)
Gradient m=23.0 to the nearest tenth
Finding the equation of the line
y-y1=m(x-x1)
y-10=23(x-1)
y-10=23x-23
y-23x=-23+10
y - 23x = -13
so, the equation of the line tangent line is
23x - y =13

PLEASE MARK ME BRAINLIEST IF MY ANSWER IS CORRECT PLEASECan someone tell me the formula of this shape so that i can solve it and would it be the ² or the ³ and last what number in this problem do i not use thank u
Answers
Answer:
660 ft³
Step-by-step explanation:
The way I'm thinking of it, we can think of it as a triangle and then extruding out from that triangle for the length.
First, the triangle:
area = base * width / 2 = 12 * 10 / 2 = 60 ft²
volume = the triangle for the length
the length is 11 feet,
so we extrude that triangle for 11 feet to get
60 ft² * 11 ft = 660 ft³
we multiply 10 ft by 12 ft by 11 ft. there are 3 instances of ft, so the corresponding exponent is therefore ³.
another way to think of the extrusion is like a rectangular prism, the formula for a rectangular prism's volume is length * width * height. we're extruding from the bottom rectangle for the whole of the height, so we multiply the area of the bottom triangle (length * width) by height.
this might be confusing so let me know if you have any questions!

8x2 – 2x - 15 =0
Answers
Answer:
x = 3/2 or x = -5/4
Step-by-step explanation:
Solve for x over the real numbers:
8 x^2 - 2 x - 15 = 0
Using the quadratic formula, solve for x.
x = (2 ± sqrt((-2)^2 - 4×8 (-15)))/(2×8) = (2 ± sqrt(4 + 480))/16 = (2 ± sqrt(484))/16:
x = (2 + sqrt(484))/16 or x = (2 - sqrt(484))/16
Simplify radicals.
sqrt(484) = sqrt(4×121) = sqrt(2^2×11^2) = 2×11 = 22:
x = (2 + 22)/16 or x = (2 - 22)/16
Evaluate (2 + 22)/16.
(2 + 22)/16 = 24/16 = 3/2:
x = 3/2 or x = (2 - 22)/16
Evaluate (2 - 22)/16.
(2 - 22)/16 = -20/16 = -5/4:
Answer: x = 3/2 or x = -5/4
