Answer:

-3

Step-by-step explanation:

Answer: The cost of a small box is $4. The cost of a large box is $7.

Step-by-step explanation:

Let s = cost of a small box and L = cost of a large box

3s + 5L = 47

11s + 10L = 114

Multiply the top equation by -2 to combine with the second equation

-6s - 10L = -94

+11s +10L = 114

L cancels out, now solve for s

5s = 20

s = 4

Now, plug the value of s back into an equation to find the value of L

3(4) + 5L =47

12 + 5L = 47

5L = 35

L = 7

Answer:

[tex]\huge\boxed{\sf Graph\ C}[/tex]

Step-by-step explanation:

Given equation is:

[tex]\sf y = \frac{3}{4} x -3[/tex]

So, Slope = 3/4 and y-intercept = -3

Let's find the slope and y-intercept for each graph:

[tex]\rule[225]{225}{2}[/tex]

Graph A:

Let's pick two coordinates to find the slope:

Coordinates are (5,1) and (0,-3)

[tex]\sf Slope = \frac{y2-y1}{x2-x1} \\\\Slope = \frac{-3-1}{0-5} \\\\Slope = \frac{-4}{-5} \\\\Slope = \frac{4}{5}[/tex]

So, This is not the required Graph.

[tex]\rule[225]{225}{2}[/tex]

Graph B:

Graph B is also not the required graph because it's y-intercept is 3 and not -3 (y-intercept is the point where the value of y is zero)

[tex]\rule[225]{225}{2}[/tex]

Graph C:

The left graph is graph C. So, This is the correct answer!

0.8 x 100=80

Answer:

He completed 80% of them and did not complete 20%.

Step-by-step explanation:

You can put this as a fraction because out of 30 passes he attempted, he made 24, so fraction is 24/30. To find the percent, you divide that and multiply by 100.

Percent:

Answer:

c

Step-by-step explanation:

we can see that the "a" value is -1, written as just "-" meaning the parabola is going to face down, this eliminates A and D, then if we solve for the x intercepts, ( set the values in the parenthesis equal to 0) we see that the intercepts are negative one and positive 3

The graph which represents the equation f(x) = -(x + 1)(x - 3) is graph C.

Given a function that has the equation form:

f(x) = -(x + 1)(x - 3)

It is required to find the graph of this function.

The equation is clearly in the form of a factorized quadratic equation.

So the graph will be clearly parabola.

Now, when the equation is expanded, the equation will be of the form:

f(x) = -(x² -2x -3)

     = -x² + 2x + 3

The leading coefficient is negative. So the parabola opens downward.

This eliminates options A and D.

The remaining options are B and C.

From the factored form, the zeroes of the function are:

-(x + 1)(x - 3) = 0

(x + 1)(x - 3) = 0

x = -1 and x = 3

That is, the graph touches the X-axis at x = -1 and x = 3.

The vertex coordinates are:

x = -b/2a = -2/-1 = 1

y = f(-b/2a) = -(1+1)(1-3) = 4

Hence the correct option is C.

Answer:

58%

Step-by-step explanation:

Lo siento. No soy bueno con el español, así que estoy usando translate. Espero que esté bien.

Entonces, para esta ecuación, usaremos un porcentaje igual o superior a 100 como se indica aquí. ([tex]\frac{es}{de}[/tex] = [tex]\frac{porciento} {100}[/tex]) Entonces tu ecuación es [tex]\frac{28}{49}[/tex] = [tex]\frac{x}{100}[/tex]

Multiplicará 28 por 100, lo que le dará 2800. Luego, dividiría 2800 entre 48, lo que le daría 58. Entonces, su respuesta sería x = 58%.

Answer:

28400cm

Step-by-step explanation:

if 9 days=7m

:.365 days=?

365×7/9

283.88888

rounded off to nearest whole number =284m

change to cm=28400cm

The speed of the object expressed in centimeters per year and rounded to the nearest whole number is 28390 cm/yr

Speed per day = Distance / Number of days

Speed per day = 7 meters ÷ 9 days = 0.7778 m/day

Converting to centimeters per year :

Hence,

0.7778 m/day = (0.7778 × 100cm) ÷ (1/365 years)

(0.7778 × 100cm) ÷ (1/365 years) = (77.78 cm ÷ 0.0027397 year)

0.7778 m/day = 28389.7 cm / year

Therefore, the speed of the object is 28390 cm/yr

Step-by-step explanation:

Answer:

x = ±4

x = 4

Step-by-step explanation:

x² = 64.

Square root both sides

√x² =√64

x= ±8

When squaring both sides, the required solution is both positive and negative since the product of two negative number is positive.

x³ = 63.

Cube root both sides

3√x³ = 3√65

x =4

This only gives a positive number not negative since the product of three negative number gives a negative number
