7X+10y=4 in slop intercept form

Answers

Answer 1

Answer: Slope-Intercept form is the equation of a line where it is solved for y. So, to put this into Slope-Intercept form you need to solve it for y.

7x + 10y = 4 Subtract 7x from both sides
10y = -7x + 4 Divide both sides by 10
y = - $(7)/(10)$ x + $(4)/(10)$ Simplify if you can
y = - $(7)/(10)x$ + $(2)/(5)$

Simplify (3x + 5) + (2x - 9) - (4x + 3).
x - 7
-x - 7
-9x - 1
9x - 1

Answers

(3x+5) + (2x-9) - (4x+3)
Open the parentheses.
3x + 5 + 2x - 9 - 4x - 3
Combine like terms.
3x + 2x - 4x + 5 - 9 - 3
Sometimes it helps to think of them separately:
3x + 2x - 4x = x (because 3+2-4=1)
5 - 9 - 3 = -7
So the final thing is
X - 7

Answer:

X - 7

Step-by-step explanation:

The table shows three unique functions. Which statements comparing the functions are true? Select three options. A. Only f(x) and h(x) have y-intercepts. B. Only f(x) and h(x) have x-intercepts. C. The minimum of h(x) is less than the other minimums. D. The range of h(x) has more values than the other ranges. E. The maximum of g(x) is greater than the other maximums.

Answers

Answer:

CDE

Step-by-step explanation:

A) Only h(x) has a y intercept which is at x=0. At this point the y intercept is 0.

B) Only f(x) have a x intercept at f(x) = 0. The graph of f(x) touches the x axis at f(x) = 0.

C) h(x) has the lowest minimum, its minimum is at -28 while f(x) have a minimum at -14 and g(x) have a minimum at 1/49

D) The range of h(x) has more values than the other ranges ranging from -28 to -28.

E) g(x) has the highest maximum, its maximum is at 49 while f(x) have a maximum at 14 and h(x) have a maximum at 0

Factor by using the perfect-square trinomial formula.

100x^2+20x+1

Answers

to factor first multily 100 and 1 and get 100

then find what 2 numbers multiply to get 100 and add to get 20

the numbers are 10 and 10

so
split the center term up
100x^2+10x+10x+1
group
(100x^2+10x)+(10x+1)
undistribute
(10x)(10x+1)+(1)(10x+1)
undistribute/reverse distributive property
(10x+1)(10x+1)
(10x+1)^2

sincethis is a perfect square problem, the answer will be in the form (ax +b) ^ 2. what can you tell from looking at the original equation? x^2does not have a coefficient in front of it, so a = 1. the second term isnegative, so b must be negative. finally, the last number 100 is thesquare of + or - 10, so b must be +10 or -10, but we already figured bhas to be negative, so b = -10

a scale drawing of a building needs to be made using the scale 1 in=170 ft.how tall will the building in the scale be if the building is 680 ft.tall?

Answers

Hi there! The answer is 4 inches.

If 1 inch on scale equals 170 feet in reality, 680 feet in reality equals 680 / 170 = 4 inches on scale (since the proportions don't change).
