I'm not 100% sure on how to figure out this equation, can can anyone help out?

Answers

Answer 1

Answer:

Aonnalin, great name :) answer as below

Step-by-step explanation:

They tell us to use slope-intercept form. This is something you will just have to remember y = mx+b

It is confusing b/c there is the other one, the point-slope formula too. but just remember both and know that the point-slope one is to get to the slope-intercept one. y-y1 = m(x-x1)

m= slope

m = (y2-y1) / (x2-x1)

P1= (0,7) in the form (x1,y1)

P2 =(8,-2) in the form (x2,y2)

m = -2-7 / 8-0

m = -9 / 8

now that we have the slope, just use either point with the point-slope

y-7 = (-9/8)(x-0)

y-7 = -9x/8

y = -9x/8 + 7

y = [tex]\frac{-9}{8}[/tex] X + 7

slope-intercept form :)

Help a girl out Jamal plans to attend a 4-year private university. He will receive $8,200 in scholarships and grants each year, and he will earn $1,900 each year through a work study program. Jamal's family will contribute $21,000 each year. How much will Jamal need to contribute?

Answers

Answer:

Jamal contribution = Total fee - scholarship & grant - study program earnings - family contribution

Step-by-step explanation:

Let total fee = x

Jamal contribution = x - 8200 - 1900 - 21000

= x - 31100

Her fee above & beyond 31100 will have to be arranged by Jamal's own contribution

The solids are similar. Find the volume V of the red solid.

Answers

Your welcome that's from my computer and got it correct

Answer:

13,564.8

Step-by-step explanation:

The ratio of the volumes of similar solids is the cube of the scale factor.

Scale factor:

red solid : blue solid = 12/10 = 6/5

Ratio of volumes:

volume red solid : volume blue solid = (6/5)^3

volume of red solid = 7850 ft^3 * (6/5)^3 = 13,564.8 ft^3

Answer: V = 13,564.8 ft^3

Which graph shows an exponential function that nears a constant value as x approaches positive infinity and has a y-intercept at (0,3)?
A. X
B. Y
C. Z
D. W

Answers

Answer:

C. Graph Z is the correct answer

Step-by-step explanation:

It touches 0,3 and the right line is going towards infinite positive x’s

#plato

The exponent function of the graph will be W. Then the correct option is D.

What is an exponent?

Let b is the base and x is the power of the exponent function and a is the leading coefficient. The exponent is given as

y = a(b)ˣ + c

Where c is the intercept.

Let the leading coefficient will be 1.

Then the equation will be

y = (b)ˣ + c

The exponent function has a y-intercept at (0, 3).

Then the exponent function is given as,

y = (b)ˣ + 2

Some points regarding exponent function.

The exponent function remains positive for the real value of the x.If the value of x approaches to the negative infinity, then the function tends to zero.If the value of x approaches to the positive infinity, then the function tends to infinity.At x = 0, the function interset the y-axis at (0, 3).

The exponent function of the graph will be W.

Then the correct option is D.

Step-by-step explanation:

A) Discriminant = b² - 4ac = (12)² - 4(9)(4) = 144 - 144 = 0

B) Since the discriminant is 0, this means the equation only has one root.

C) The root is real in this case since the discriminant is not negative. Otherwise, we would have two imaginary roots if it were (remember that complex roots come in pairs)

Solve for x, rounding to the nearest hundredth.
70 - 2^3x = 35

Answers

Answer:

x=4.375

Step-by-step explanation:

Answer:

x= 1.71

Step-by-step explanation:

We need to isolate x in the equation, first subtract 70 from the left side, so the equation is, -[tex]2^{3x\\}[/tex]=-35. There is a negative sign in both equations so we cancel them out so our equation is [tex]2^{3x\\}[/tex]=35. Now we use log, so our equation now looks like {log(35)/log(2)}/3=x. When we do it out we get that x=1.70976, and when rounded we get, x-1.71.

What is the equation of a circle with a center located at (-3, 4) and a diameter of 14?

Answers

Answer: (x + 3)^2 + (y - 4)^2 = 49

Step-by-step explanation:

The equation of a circle given the center and radius: (x - h)^2 + (y - k)^2 = r^2

Given: center (-3,4) ; h = -3 and k = 4

diameter = 14

To find the radius: divide the diameter by 2 = 14/2 = 7 = r

Center: (-3,4) and radius: 7

Equation of a circle: (x - h)^2 + (y - k) ^2 = r^2

Substitute h = -3, k = 4, r = 7

(x - (-3))^2 + (y - 4)^2 = 7^2

Answer:

Equation of the circle: (x + 3)^2 + (y - 4)^2 = 49
