write two numbers that multiply to the value on top and add to the value on the bottom.
​

Answer: after 3 seconds

when  the ball hit the ground => - 5t² + 14t + 3 = 0

⇔ (5t + 1)(t - 3) = 0

⇔ t = 3 or t = -1/5

but t  is a positive integer => t = 3

so the ball will hit the ground after 3 seconds

Answer:

Exact length = 2*sqrt(137)   cm

Approximate length = 23.409  cm

====================================================

Work Shown:

Use the Pythagorean theorem

a^2 + b^2 = c^2

8^2 + 22^2 = c^2

64 + 484 = c^2

548 = c^2

c^2 = 548

c = sqrt(548)

c = sqrt(4*137)

c = sqrt(4)*sqrt(137) ..... use the rule sqrt(x*y) = sqrt(x)*sqrt(y)

c = 2*sqrt(137)  .... this is the exact length

c = 23.4093998214392 ... use your calculator to find the approximate length

c = 23.409

Ask your question below.

Step-by-step explanation:

According to the power law of indices, when base numbers are the same and multiplying,add their exponents but when base numbers are the same and dividing, subtract their exponents.

Applying the above rule to the numerators,we have 7^(8+3+4)=7^15

Applying to the denominators we have,

7^(9+5)=7^14

Now we have 7^15/7^14=7

Answer:

The coordinates of point A' will be: A'(-2, 0)

Step-by-step explanation:

We know that a translation is basically a transformation that occurs when an object is moved from one place to another place.

Translation does not change the size, orientation, or shape of the original object.

Translating a point P(x, y) 4 units up means we need to add to use P'(x, y+4), that is adding 4 units to the y-coordinate of the point P'(x, y).

Now we have to translate the triangle 4 units up. So, use the formula

P(x, y) → P'(x, y + 3)

Thus, the coordinates of point A' will be:

A(-2, -3) → A'(-2, -3+3) → A'(-2, 0)

Therefore, the coordinates of point A' will be: A'(-2, 0)

Answer:

We have the system of equations:

y=1/3x+5

y=2/3x+5

To solve it graphically, we need to graph both lines and see in which point the lines intersect.

You can see the graph below, and you can see that the lines intersect in the point (0, 5)

Now, we can also solve this analytically.

We can use the fact that for the solution, we need y = y.

Then we can write:

(1/3)*x + 5 = (2/3)*x + 5

First, we can subtract 5 in both equations to get:

(1/3)*x = (2/3)*x

This only has a solution when x = 0.

Replacing x = 0 in one of the equations, we get:

y = (1/3)*0 + 5 = 5

Then the solution is x = 0, and y = 5, as we already could see in the graph.

Rewrite the whole as a fraction using  4  as the denominator :

   14 • (5x - 24) =  ——————————————  =  ——————————————————

                           1                    4          

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

5.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

Answer:

B.The slope is approximately 1.33 and the y-intercept is 2.

Step-by-step explanation:

On the graph we are going based off where the line starts and in this case it starts on the y line and that shows our y-intercept is 2. The line also doesn't have a rate of change that is directly being put onto an intersecting point like (2,2) which would make it a decimal 1.33.

Answer:

B. The slope is approximately 1.33 and the y-intercept is 2.

Step-by-step explanation:

We can eliminate answers C and D because the y-intercept is 2.

The slop is approximately 1.33 because if we go over 1 unit, we must go up approximately 1.33 units to follow the line.

Answer:150

Step-by-step explanation:

The mass of 348mL serving soup is 216 grams

The serving is proportional; so, we have:

[tex]\mathbf{290mL = 180g}[/tex]

[tex]\mathbf{348mL = x}[/tex]

Where x represents the mass of 348mL serving soup.

Cross multiply.

So, we have:

[tex]\mathbf{x \times 290mL = 180g \times 348mL}[/tex]

Cancel out common units

[tex]\mathbf{x \times 290 = 180g \times 348}[/tex]

[tex]\mathbf{x \times 290 = 62640g}[/tex]

Divide both sides by 290

[tex]\mathbf{x = 216g}[/tex]

Hence, the mass of 348mL serving soup is 216 grams

Answer:

Renee has 9 Chocolate chip cookies and 3 peanut butter cookies.

Step-by-step explanation:

This is a system of equations:

C + p = 12

C = 3P

All you need to do is substitute C for 3P in the first equation.

C + P = 12

3P + P = 12

4P = 12

Divide both sides by 4

4P/4 = 12/4

P = 12/4

P = 3

Now, substitute P for 3 in the first equation.

C + P = 12

C + 3 = 12

Subtract 3 from both sides

C + 3 - 3 = 12 - 3

C = 12 - 3

C = 9

C = 9, P = 3
