Is (-7, -3) a solution to this system of equations?

x = -7
y = -x - 10

Yes or no

Answers

Answer 1
Answer:   Yes

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

Explanation:

The point (-7,-3) means x = -7 and x = -3

Right off the bat, the first equation x = -7 is proven true based on the first coordinate.

Let's now plug the coordinates into the second equation.

y = -x-10

-3 = -(-7)-10

-3 = 7-10

-3 = -3

Which is a true statement.

Both equations are true when (x,y) = (-7,-3)

This is why it is a solution to the system. It turns out it's the only solution to this system. This system is consistent and independent.

You can use a graphing tool like Desmos to plot the two equations, and you should see them crossing at the point (-7,-3)

Answer 2

Answer:

The answer is yes

*View the attached graph to check your answer graphically.*

Step-by-step explanation:

x = -7

y = -x - 10

For this problem, I will be using substitution, since the second equation is already in the slope-intercept form.

First, I will substitute the first equation, for x, into the first equation:

x = -7

y = -x - 10

y = -(-7) - 10 <== multiplying two negatives, makes a positive

y = 7 - 10

y = - 3 <== the value of y

Now, we find the value of x by substituting - 3 for y:

y = -x - 10

- 3 = -x - 10

+10     +10

7 = -x <== you can't have a negative variable

/-1    /-1

-7 = x <== the value of x

(x, y) ==> (-7, -3)

Therefore, yes (-7,-3) is a solution to this system of equations.

  the women won 1 fewer matches than the men

Step-by-step explanation:

In a pie chart, the fraction of the total that is represented by any sector is the ratio of the angle subtended by that sector to 360°.

__

For the men's team, the winning games represent 150°/360° = 5/12 of all games played. The men played 24 games, so they won ...

  5/12 × 24 = 10 . . . . games won

__

For the women's team, the winning games represent 180°/360° = 1/2 of all games played. The women played 18 games, so they won ...

  1/2 × 18 = 9 . . . . games won

The number of matches won by the men is larger than the number of matches won by the women. (Yes, the women won a larger fraction of their matches played, but not a larger number.)

Find the value of x for which allb

B. 145
C. 140
D. 47

Answers

Answer:

A. 35

Step-by-step explanation:

a || b .....(given)

line c is their transversal.

-> x° + (3x + 40)° = 180° (Interior angles on the same side of transversal)

-> (3x + 40 + x)° = 180°

-> (4x + 40)° = 180°

-> 4x + 40 = 180

-> 4x = 180 - 40

-> 4x = 140

-> x = 140/4

-> x = 35

If everybody scores 6 then the possible equation could be 6p = 42.

p represents the people on the team.

Solve for the variable p:

Your father says that your journey will be about 3,000 miles. Is this a close estimation of the distance? Explain your reasoning.

Answers

Based on the cities you will go through and your starting and finishing points, your father's estimate is a close estimation of the distance.

How far is New York from San Jose?

The map is not provided so we will use a general map.

The distance from San Jose to Denver is around 1,301 miles.

The distance from Denver to Chicago is around 1,004 miles.

The distance from Chicago to New York is around 796 miles.

Added together we get:

= 1,301 + 1,004 + 796

= 3,101 miles

This is close to the 3,000 miles your father estimated.

Step-by-step explanation:

mean of x,y,z

(x+y+z)/3=mean

so

represent next test score as x

89+94+82+84+98+x

count how many terms ther are (6 terms)

mean is 90

(89+94+82+84+98+x)/6=90

add the like terms

(447+x)/6=90

multiply both sides by 6 to clear fraction

447+x=540

subtract 447 from both sides

x=93

The diameter of wrapper is the line that passes through its circumference

The smallest diameter of wrapper that will fit the candy bar is 8 cm.

How to determine the smallest diameter?

The diven parameter is:

AD = 4 cm

AD = DC

AC = AD + DC

Substitute AD = DC in AC = AD + DC

So, we have:

AC = AD + AD

AC = 2AD

Substitute 4 for AD

AC = 2 * 4

AC = 8

Hence, the smallest diameter of wrapper that will fit the candy bar is 8 cm.
