Answer: x = 16, y = 9

D. x + y = 25

x - y = 7

Step-by-step explanation:

        Let x be a number and y be another. First, I will write the problem out using equations. Then I can solve by graphing, see attached. Their point of intersection is the answer, x = 16 and y = 9.

    The sum of two numbers is 25

x + y = 25

    Their difference is 7

x - y = 7

          D. x + y = 25

          x - y = 7

Find equation of old line first

Equation in slope intercept form

Translated 4units left(x+4)

Translated 6 units up(y intercept +6)

Put it.

Answer:

  y = -3x -2

Step-by-step explanation:

The equation of the given line, with slope -3 and y-intercept 4, can be written in slope-intercept form as ...

  y = -3x +4

When the line is translated by (h, k), it can be written as ...

  (y -k) = -3(x -h) +4

__

Here, we want to translate the line -4 in the x-direction and 6 in the y-direction. That is, (h, k) = (-4, 6). Using these values in the above equation, we have ...

  y -6 = -3(x -(-4)) +4

  y = -3x -12 +4 +6 . . . . simplify, add 6

  y = -3x -2

__

The attached graph shows the original line (red) with its y-intercept, and the translated line (green) with that y-intercept moved 4 units left and 6 units up.

Answer:

Firstly, we would have to find out how much is 25% of 32.

So we do this:

32 x 0.25 = 8

Now that we know that 8 is 25 % of 32

We simply add 8 to 32

and get the final answer which is 40

Answer:

10,000 cm²

Step-by-step explanation:

m² to cm² conversion

So, the surface area of the prism in cm² is 10,000 cm²

Step-by-step explanation:

could not find the formula ?

the volume is a cylinder is

ground area × height

the ground area is a circle, so we get

pi×r²×h

where r is the radius, h is the height.

therefore

pi×4.5²×2.9 = 184.4900286... ft³ ≈ 184.5 ft³

The choice that matches the graph of the function as is defined to us is: Graph A.

A function in math is a rule or expression that defines a relationship between one variable (the input or independent variable) and another variable (the output or dependent variable).

We are given a function f(x) as:

f(x)=   2x    if x < 3 and 4 if  x ≥ 3

This means that in the region (-∞,3) the graph of a function is a straight line that passes through the origin and has a open circle at x=3. and in the region [3,∞) the graph is a straight horizontal line i.e. y=4.

Hence, the graph of this function is: Graph A.

Answer:

<ABC= 45 degrees

Angles on a straight line add up to 180

3x+ x= 180

4x=180

x=180÷4

x=45

Answer:

Measure of ABC = 15 degrees.

Step-by-step explanation:

We draw 2  lines parallel  to l and m , one passing through pont C ( n) and the other passing through point D (p).

If < abc = x degrees then the angle below line n = 25 - x. As the one above = x degrees ( alternate to < ABC).

The angle below line p = < DEF 3x degrees (alternate angles)

So as  < CDE = 55:

25 - x + 3x = 55

2x = 30

x = 15.

So < ABC = 15 degrees.

Answer:

439.5 million

Step-by-step explanation:

Expand the numbers:

439.5 million = 439500000

484 million = 484000000

439.5 million is smaller because 3 < 8 in the tens of millions place.

Answer:

3/2

Step-by-step explanation:

To find the slope, choose two points.

For example, choose (2, 5) and (4, 8).

Now find the difference between the y-coordinates.

8 - 5 = 3

Find the difference between the x-coordinates.

4 - 2 = 2

Divide the difference in y by the difference in x. That is the slope.

slope = 3/2

The population of bacteria after 672 hours is 36000.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

According to the given question we have

The number of bacteria double is 336 hours.

And, the current population of bacteria is 9,000.

Therefore,

The population of bacteria after 336 hours = 9,000×2 = 18,000

⇒ the population of bacteria after 672 hours  = 18000 × 2 = 36000  

Hence, the population of bacteria after 672 hours is 36000.

Answer:

x = 3, y = -2

Step-by-step explanation:

Solving the bottom equation for y, we have y = 4 - 2x. Substitute that into the top equation, and solve for x.

4x - 3(4 -2x) = 18

4x - 12 + 6x = 18

10x - 12 = 18

10x = 30

x = 3

From this, we have y = 4 - 2(3) = 4 - 6 = -2

Answer:

increasing

increasing

decreasing

increasing

decreasing

neither

Step-by-step explanation:

"increasing" just means the graph is going up from left to right.

"decreasing" means going down from left to right.

"neither increasing nor decreasing" means flat, horizontal, not going up or down.

Imagine you are walking on the x-axis, starting on the left, the numbers on the axis are like house addresses as you walk down the street. The column that says "interval" is saying where you are looking at along the axis.

-7 < x < -3 means from -7 to -3 on the x-axis. That piece of the curve IS going up from left to right. From -3 to -1 is also going up, so its increasing. From -1 to 1 the graph goes down, that's decreasing. Then it goes up again, then down, then flat. (incr, decr, neither)

Any slanted line or curve can be seen as going up or going down, depending on which direction you are going. But in this case only consider left to right ONLY. Then you can tell if its increasing or decreasing.

75 seconds to run 180 meters

Step-by-step explanation:

(180m) / (2.4m/s) = 75 seconds

75 seconds to run 180 meters, but if we take into consideration the initial 39 seconds, then the total time it took to run (75s + 39s) was 114 seconds.

The question didn't explicitly ask the total time it took, but the time it took to run 180 meters.
