Solve using the quadratic formula: -16x^2-4x + 382

Answer:

2280

Step-by-step explanation:

10 percent is 3800

so 5 percent would be half of that 1900

so 6 percent would be 2280

Answer:

3) 5/2

Step-by-step explanation:

5x - 2y = 20

(First, put it in slope intercept form: y = mx + b).

5x - 2y - 5x = 20 - 5x --> Subtracted 5x on both sides of the equation

- 2y  = -5x + 20 --> Simplified

-2y/-2 = (-5x + 20)/-2 --> Divided by -2 on both sides

y = 2.5x - 10 --> Simplified

Since formula is, y = mx + b, then:

m (slope): 2.5

b (y-intercept): -10

Therefore, the answer is 3) 5/2

Hope this helped! <3

Let's solve for y.

5x − 2y = 20

Step 1: Add -5x to both sides.

5x−2y+−5x=20+−5x

−2y=−5x+20

Step 2: Divide both sides by -2.

−2y/−2  =  −5x + 20/−2

y =  5/2x − 10

Answer:

y =  5/2x − 10

Slope = x, therefore, the slope = 5/2.

Given :

60% of dads prefer to watch football on TV.

40% prefer to watch basketball.

To Find :

If 200 dads were surveyed, how many more preferred football to basketball.

Solution :

Number of dad prefer football over basketball is :

[tex]N = 200\times \dfrac{60}{100}\\\\N = 120[/tex]

Therefore, 120 dad's prefer football over basketball.

Answer:

I believe it would be 3.5

Step-by-step explanation:

2 is half of 4, the measurement for that same side on the connected triangle, by that logic, x would be half of 7.

7 ÷ 2 = 3.5

Answer:

i think it is 9

Step-by-step explanation:

Answer:

x = 60

Step-by-step explanation:

The value of x is 60

firstly, what we have is an equilateral triangle

For an equilateral triangle, the measure of the angle is 60

Now, looking at one of the angle at the base, we can see that the measure of angle x is an alternate angle to one of the angles at the base

Answer/Step-by-step explanation:

Opposite angles of a parallelogram are equal to each other.

Therefore, <S = <U, and <T = <V

Consecutive angles of a parallelogram are supplementary.

Therefore,

m<S + m<V = 180°

50° + m<V = 180°

m<V = 180° - 50° (subtraction property of equality)

m<V = 130°

Answer:

D. 25

Step-by-step explanation:

By geometric mean property:

[tex] {(12)}^{2} = LM\times JM \\ \\ 144 = LM\times16 \\ \\ LM = \frac{144}{16} \\ \\ LM = 9 \\ \\ [/tex]

JL = JM + LM = 16 + 9 = 25

20 Input

10 output

Step-by-step explanation:

Here, we want to select the input and output that works

From the diagram, the correct answer is 20 and 10

Let us look at how the rule is followed;

divides input by 2

20/2 = 10 which is the output

Subtract 10 to get output

20-10 = 10

Step-by-step explanation:

Unit Rate: k=200x

Answer:

The image of the point is (8, 4)

Step-by-step explanation:

If the point (x, y) dilated by a scale factor k centered at the origin, then its image is (kx, ky)

Let us solve the question

∵ The point is (2, 1)

∴ x = 2 and y = 1

∵ The point dilated by a scale factor of 4 centered at the origin

∴ k = 4

→ By using the rule above multiply each coordinate of the point by 4

∵ The image of the point is (kx, ky)

∵ kx = 4 × 2

∴ kx = 8

∵ ky = 4 × 1

∴ ky = 4

∴ The image of the point is (8, 4)
