Identify the solution to the system of equations

Answers

Answer 1

Answer:

Answer:

(-2, -1).

Step-by-step explanation:

When trying to find the solution to a system of equations graphically, all you need to do is find the point of intersection between the two equations.

In the graph pictured, we can see that the two equations intersect at (-2,-1).

What are the x intercepts of the graph of this function? Y=6*2+10x - 4

Answers

x intercpe is when y=0

0=6x^2+10x-4
factor
0=2(3x^2+5x-2)
assume
0=3x^2+5x-2
0=(x+2)(3x-1)
set to zero
x+2=0
x=-2
3x-1=0
x=1/3

x intercepts are -2 and 1/3

D is answere

y = 6x^2 + 10x - 4
= 6x^2 + 12x - 2x - 4
= 6x(x + 2) - 2(x + 2)
= (6x - 2)(x + 2)

X intercepts are: -2 and 1/3

it is D

The formula d = ft can be used to calculate the distance (d) an object travels using its rate of speed (r) and the time it travels (t). Using the formula, which shows the rate the object traveled?

Answers

In that first sentence, you should have typed d = r * t
Rate would be calculated as:
rate = distance / time

Both circle Q and circle R have a central angle measuring 110°. The area of circle Q's sector is 4π cm2, and the area of circle R's sector is 9π cm2. The radius of circle Q is 7 cm. Which is the radius of circle R

Answers

The area of circle Q's sector = 4π $cm^2$

the area of circle R's sector = 9π $cm^2$

The radius of circle Q = 7 cm

We need to find the radius of circle R that is x

Given : Both circle Q and circle R have a central angle measuring 110°

So the radius of circle R to the radius of circle Q is equal to the square root (area of circle R to the radius of circle Q)

$(Radius-R)/(Radius-Q) = \sqrt{(area-R)/(area-Q) }$

Plug in all the values

$(x)/(7) = \sqrt{( 9\pi)/( 4\pi )$

$(x)/(7) = \sqrt{(9)/(4)}$

$x = (3)/(2) * 7 = 10.5$

Therefore , the radius of circle R = 10.5 cm

The answer is 10.5 :)

5 students participated in a push-up competition.The amount of push-ups each student completed is listed: 12, 7, 10, 11,5
What was the mean number of push-ups?

Answers

Answer: 9

Step-by-step explanation:

Formula : Mean = $\frac{\text{Sum of observations}}{\text{Number of observaions}}$

Given: 5 students participated in a push-up competition.

The amount of push-ups each student completed is listed: 12, 7, 10, 11,5.

Mean = $(12+7+10+77+5)/(5)$

$=(45)/(5)=9$

Hence, the mean number of push-ups = 9
