Answer:

  (D)  -1.3 + 1.9

Step-by-step explanation:

The number being subtracted in the given expression is -1.9. The opposite of that number is +1.9.

If we are to show equivalence of subtraction and adding the opposite, we expect to do so with ...

  [tex]-1.3-(-1.9)=\boxed{-1.3+1.9}[/tex]

This is not a choice that is presented in this problem statement, so we suppose it is D (not shown).

Answer:

The result would be 2 > 1 because when you divide both sides, the < has to be flipped around

Answer:

y=5/4x

Step-by-step explanation:

First, take two points from the line. For example, I'll take (4,5) and (-4,-5)

The equation for slope (m) is (y2-y1)/(x2-x1)

let's label the points

x1=4

y1=5

x2=-4

y2=-5

now substitute into the equation:

m=(-5-5)/(-4-4)

m=-10/-8

m=5/4

Next, let's use point slope form, which is y-y1=m(x-x1)

Substitute x1, y1, and m

y-5=5/4(x-4)

y-5=5/4x-5

add 5 to both sides

y=5/4x

Hope this helps!

Answer:

The correct answer is graph B.

Hope This Helps! Sorry for late answer!

Answer:

its A because because the slope of the y-intercept is on the possative base towards the iquantities which is to be a posative number, in that case the y-intercept adds a 1 to the x which would lead towards the negative side therefor your answer will be y < -x -2

Step-by-step explanation:

The 10th term of this arithmetic sequence 100,110,120,130...​ is 190.

An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference

d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.

In a geometric sequence numbers are written in the same constant ratio(r).

It means every next number is a multiple of a common constant and the previous number.

r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.

Given, An arithmetic sequence 100,110,120,130...​

First term a₁ = 100, Common difference(d) = 130 - 120 = 120 - 110 = 10.

We know nth term of an arithmetic sequence is aₙ = a₁ + (n - 1)×d.

aₙ = 100 + (n - 1).10.

aₙ= 100 + 10n - 10.

aₙ = 10n + 90

So, the 10th term a₁₀ = 100 + (10 - 1).10 = 100 + 90 = 190.

The cost for 20 students would be $120

Step-by-step explanation:

We know that 4x5=20 therefore we will multiply 30x4 which will give us 120.

Our final answer would be $120

The ball is lower than the bridge at the interval [2, 3.385] and (-∞,0) contains negative values

The equation of the function is given as

h(t)= -16t^2 + 32t + 75

The above equation is a quadratic equation

When the balloon is less than the bridge i.e. a height of 75 feet, we have

h(t) < 75

So, we have the following equation and inequality

h(t)= -16t^2 + 32t + 7

h(t) < 75

Next, we plot the equation and inequality on a graph (see attachment)

The equations intersect at

t = 0 and t = 2

Remove when t = 0

t = 2

The ball hits the ground at t = 3.385

So, the interval is [2, 3.385]

Also, (-∞,0) is not included in the solution because time cannot be negative

Answer:

17%

Step-by-step explanation:

to find the percentage of something, you have to fill out the following formula:

x/100 = 21.25/125. Basically that is saying that some percent out of 100 is equal to 21.25 out of 125. To solve that, you have to cross multiply:

125x = 2125

then you have to divide, to single out x:

the answer is 17

so it is 17%

Answer:

Domain is all real numbers.

Range is -3 to infinity that is y >= -3 (that is y -3)

Increasing from x > -4 ( that is from -4 to +infinity) that is to right of -4

Decreasing from x <-4 (that is -infinity to -4) that is to left of -4

This has a minima at x= -4 with y= -3. We can write as (-4, -3)

Maxima is not there as it is going to infinity

Answer:

The value of x is 6

Step-by-step explanation:

The formula of the area of the rectangle is A = l × w, where

In the rectangle ABCD

∵ AB = 2x cm

∴ l = 2x

∵ AD = x cm

∴ w = x

→ Use the formula of the area above to find its area

∵ A = 2x × x

∴ A = 2x²

∵ The area of the shaded region = 50 cm²

→ When the shaded region removed, then the remaining area is the

   unshaded region

∵ The area of unshaded region = 22 cm²

∵ The area the ABCD = area the shaded region + area unshaded region

∴ A = 50 + 22

∴ A = 72 cm²

→ Equate the two right side of A

∵ 2x² = 72

→ Divide both sides by 2

∴ x² = 36

→ Take √  for both sides

∴ x = 6

∴ The value of x is 6
