Hi there!
The solution to this system of equations is the point where the graphs of the equations intersect.
That point only will make both equations true.
So, where do these graphs meet?
First, look at the x-coordinate. It's -6.
Now, look at the y-coordinate. It's -2.
Thus, the answer is
(-6, -2)
Hope it helps!
Ask me if you have any doubts.
Enjoy your day!

Answer:
Given Below. [ done below, side changing which changed sign + to - and - to + ]Step-by-step explanation:
6. x + 21 = 56
→ x = 56 – 21
→ x = 35
7. n – 13 = 8
→ n = 8 + 13
→ n = 21
8. w – 7 =41
→ w = 41 + 7
→ w = 48
9. b + 22 = 89
→ b = 89 – 22
→ b = 67
10. z – 53 = 26
→ z = 26 + 53
→ z = 79

2. Tell whether the ordered pair (-1,-2) is the solution of the system. x + y =
-3 and 2x - y = -4*
Answer:
Not the solution tp the system because the ordered pair should be true for both equations. However the last equation is not true.
Step-by-step explanation:
(-1,-2) is the solution of the system. x + y =-3 and 2x - y = -4*
x + y =-3 :
(-1)+ (-2) = -3
-1-2 =-2 -3=-3
2x - y = -4:
2(-1)-(-2)=-4
(-2) -(-2)= -4

At the beginning of the school year, the bookstore
had 130 copies of the third grade math book
By the end of the first month of school, all but
16 books were sold. How many math books were
sold during the first month of school?
Answer:
114 books.
Step-by-step explanation:
I'm pretty sure what you have to do is just subtract 16 from 130. (130-16).
When you do that you get 114 books. (sorry for basically no explanation.)
Braden is admiring a statue in Springfield Park. The statue is 3.4 meters taller than he is, and Braden is standing 8 meters away. How far is it from the top of the statue to Braden's head? If necessary, round to the nearest tenth. meters
Answer:
8.69 m
Step-by-step explanation:
We have to use the Pythagorean theorem here
Statue is 3.4 tall, that's one leg of the right traingle
Braden is 8 meters away, that's the longer leg of the right triangle
the hypotenuse would be the distance between Braden's head and the top of the statue (let's assume it is X )
x^2 = 3.4^2 + 8^2 = 11.56 + 64 = 75.56
x = 8.69

A serving of chickpeas contains 1,850 milligrams of potassium. How many grams of potassium is that?
Answer:
1.85 grams
Step-by-step explanation:
1 milligram is equal to 0.01 gram
so 1850 should be equal to 1.85 grams
Answer: 1.85 grams of potassium.
Step-by-step explanation: Since 1,000 milligrams is equal to 1 gram, you have to divide 1850 by 1000. The results will be 1.85.
Identify the slope and y-intercept of each linear function's equation.
Answer:
1) Slope = -1, y-intercept = 3
2) Slope = 1, y-intercept = -3
3) Slope = -3, y-intercept = 1
4) Slope = 3, y-intercept = -1
Step-by-step explanation:
In order to identify slope and y-intercept, you must find where each variable hits each axis when the other is 0.
For example, to find the y intercept of y=2x-4, you would substitute 0 in for x and solve for y.
y = 2(0)-4 --> y = -4
Thus, the point is (0, -4) with slope of 2. (The slope can be found by identifying the number, m, in front of 'x' from the equation y = mx + b.
Answer:
A. y = 3x-1; slope is 3 and y-intercept is -1
B. -x+3 = y; slope is -1 and y-intercept is 3
C. x-3 = y; slope is 1 and y-intercept is -3
D. y = 1-3x; slope is -3 and y-intercept is 1

What is the rule for the function shown in the table?
Input x -2, -1, 0, 1, 2
Output y 4, 1, -2, -5, -8
y = -2 x
y = x – 6
y = -3 x - 2
y = -2 x – 2
Answer:
y = - 3x - 2
Step-by-step explanation:
The function is linear and can be expressed in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (- 1, 1) ← 2 ordered pairs from the table
m = [tex]\frac{1-4}{-1-(-2)}[/tex] = [tex]\frac{-3}{-1+2}[/tex] = [tex]\frac{-3}{1}[/tex] = - 3 , then
y = - 3x + c
To find c substitute any ordered pair into the equation
using (0, - 2 ) , then
- 2 = - 3(0) + c = 0 + c ⇒ c = - 2
y = - 3x - 2 ← function rule
Answer:
y = - 3x - 2

[tex]= [2 \cdot 3^{(1-\frac{2}{3})}] - [2^{\frac{1}{3}}\cdot 3^{(1+\frac{1}{3} - \frac{2}{3})}]\\\\= [2 \cdot 3^{(\frac{1}{3})}] - [2^{\frac{1}{3}}\cdot 3^{(\frac{2}{3})}]\\\\= 2\sqrt[3]{3} - \sqrt[3]{2}\sqrt[3]{9}\\\\=2\sqrt[3]{3} - \sqrt[3]{18}[/tex]

Which expression finds the measure of an angle that is coterminal with a 45° angle? 45° 90° 45° 180° 45° 270° 45° 360°.
Coterminal angles are measured from the positive x-axis. The coterminal angle for angle 45° is (270°+45°).
What are coterminal angles?Coterminal angles are angles that are made by the positive x-axis of the coordinate plane.
Given to us
θ = 45°
We know that coterminal angles are those angles that are measured from the positive x-axis of the coordinate plane.
In order to find the angle coterminal with a 45° angle, we will deduct θ from 360°, therefore we will measure the from positive x-axis but in the clockwise direction.
[tex]\theta _1 = 360^o - \theta\\\\\theta _1 = 360^o - 45^o\\\\\theta _1 = 315^o\\\\\theta _1= 270^o + 45^o[/tex]
Hence, the coterminal angle for angle 45° is (270°+45°).

which of the following is a linear function? (89 POINTS)HURRY PLSSSSS
A linear function is a straight line formed on a coordinate plane.
To classify an equation as a linear function:
It must not have any exponent in the equation. If there is a fraction, the denominator of that fraction must not multiply by x.If any of these two occurs in an equation, the line can form a curve in a line, which is a non-linear function. A non-linear function is a curved line formed on a coordinate plane.
Option A - y = x³ + 1:
This equation has an exponent in the variable x. Hence, this is a non-linear function.Option B - 5x/6 = y - 4:
This equation has no exponents in the equation. Hence, this is a linear function and also our answer.Option C - y = 8x²
This equation has an exponent in the term 8x². Hence, this is a non-linear function.Option D - y = 1/5x
The denominator of the fraction on the RHS side is multiplied by x. Hence, this is not a linear function.Hence, Option B is correct.

Answer:
3500[tex]\pi[/tex] = 10995.57 in³ (nearest hundredth)
Step-by-step explanation:
area of a circle = [tex]\pi r^2[/tex]
⇒ area of a semicircle = [tex]\frac{1}{2}\pi r^2[/tex]
⇒ area of a quarter circle = [tex]\frac{1}{4}\pi r^2[/tex]
total area = 5 circles + 10 semicircles + 100 quarter circles
⇒ total area = [tex]5\pi r^2 +(10\times \frac{1}{2}\pi r^2)+(100 \times \frac{1}{4}\pi r^2)[/tex]

Find the sum of the first 8 terms of the following sequence. Round to the nearest hundredth if necessary 6,−4, 8/3
Step-by-step explanation:
with the introduction of fractions it is clear we are multiplying things to get the sequence.
that makes this a geometric sequence, meaning that every new term is created by multiplying the previous term by a certain constant number, the ratio r.
what do we have to multiply with the first term (6) to get -4 ?
6×r = -4
r = -4/6 = -2/3
to check we use the same factor with the second term and see, if we get the predefined third term :
-4 × -2/3 = 8/3
correct, perfect.
so,
a0 = 6
an = an-1 × -2/3 = a0 × (-2/3)^(n-1) = 6 × (-2/3)^(n-1)
for the sum of a finite number of terms of a geometric sequence the formula is :
Sn = a0×(r^n - 1) / (r - 1) if |r| > 1
Sn = a0×(1 - r^n) / (1 - r) if |r| < 1
Sn = a0×n if r = 1
in our case : |-2/3| = 2/3 < 1
S8 = 6×(1 - (-2/3)⁸) / (1 - (-2/3)) =
= 6×(1 - 256/6561) / (3/3 - -2/3) =
= 6×(6561/6561 - 256/6561) / (5/3) =
= 6×(6305/6561) × (3/5) = 2×(6305/2187) × (3/5) =

An angle bisector of a triangle divides the opposite side of the triangle into segments 6 and 4 in. long. The side of the triangle adjacent to the 6-in. segment is 9 in. long. How long is the third side of the triangle?
Answer:
6 in
Step-by-step explanation:
The angle bisector divides the opposite side into segments that are proportional to the other 2 sides.
let the third side of the triangle be x , then
[tex]\frac{9}{x}[/tex] = [tex]\frac{6}{4}[/tex] ( cross- multiply )
6x = 36 ( divide both sides by 6 )
x = 6
The third side of the triangle is 6 in

Answer:

The total of cm in the 1 yard based upon 30.5 centimeters in a foot will be 91.5 centimeters.
What is multiplication?Multiplication is the general procedure in mathematics in which we multiply two or more numbers to each other to find a new multiplied number.
In another word, multiplication is nothing but changing one value by-product of another value
Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.
Given that
1 feet = 30.5 centimeters
Given that
1 yard = 3 feet
Hence 1 yard = 3 × 30.5 centimeter.
1 yard = 91.5 centimeters hence in 1 yard there will be 91.5 centimeters
