#2: Solve the linear system below using the elimination method. Type your
answer as an ordered pair in the form (#,#). *
5x + 7y = 33
11x + 7y = 39
+
The given linear system is:
[tex]\displaystyle \left \{ {{5x+7y=33} \atop {11x+7y=39}} \right.[/tex]
The question is asking to solve using elimination. When eliminating, you can either eliminate x or y. In this system, y is much easier to eliminate. The y variable in both equations are 7y. To eliminate, one of them has to be negative, so multiply one of the equations by -1.
I will be multiplying the second equation by -1.
[tex]\displaystyle (11x + 7y = 39) \times -1 = -11x-7y=-39[/tex]
Rewrite the system:
[tex]\displaystyle \left \{ {{5x+7y=33} \atop {-11x-7y=-39}} \right.[/tex]
Subtract:
[tex]5x+7y=33\\-11x-7y=-39[/tex]
[tex]5x-11x=33-39\\-6x=-6[/tex]
Lastly, you need to leave the variable x alone. The variable is currently -6x or -6 times x. To remove it, you need to do the opposite of it, which is dividing by -6.
[tex]\displaystyle \frac{-6x}{-6} =\frac{-6}{-6}[/tex]
[tex]\displaystyle x=1[/tex]
Now that you have the value of x, substitute it into one of the equations to find y. I will be substituting it into the first equation.
[tex]5x+7y=33 \rightarrow 5(1)+7y=33[/tex]
Open the parentheses and multiply:
[tex]5+7y=33[/tex]
Move 5 to the other side to leave the variable alone:
[tex]5+7y-5=33-5[/tex]
You will be subtracting since you're "removing" it by doing the opposite of it.
[tex]7y=28[/tex]
Lastly, divide both sides by 7 to leave y alone.
[tex]\displaystyle \frac{7y}{7} =\frac{28}{7}[/tex]
[tex]y=4[/tex]
[tex]\displaystyle (x,y) \rightarrow (1, 4)[/tex]
The answer is (1, 4).
Answer:
(1, 4)
Tbh this question was a bit of a challenge for me but hopefully it helps ya.
Step-by-step explanation:
First, let's solve for y. So we have to eliminate the x values.
(5x + 7y = 33 ) *11
(11x + 7y = 39) *-5
___________
55x + 77y = 363
-55x -35y = -195 This eliminates the x value.
42y = 168 Divide both sides by 42 to isolate y: 168/42= y = 4
Now let's solve for x.
(11x + 7y = 39) *7
(5x + 7y = 33 ) *-7
___________
77x + 49y = 273
-35x -49y = -231 This cancels out the y values, which leaves 42x = 42
x = 1 and y = 4, so the answer is (1, 4)

The Graph transformation of [tex]f(x) = 7^x[/tex] which stretched vertically by a factor of five is [tex]g(x) = 5(7^x)[/tex] .
What is graph transformation?Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph .
According to the question
The graph of [tex]f(x) = 7^x[/tex] stretched vertically by a factor of five .
i.e
we have to make change is graph equation so y axis changes 5 times .
Therefore ,
[tex]f(x) =( 7^x ) * 5[/tex]
The Graph transformation of f(x) is
[tex]g(x) = 5(7^x)[/tex]
Hence, the Graph transformation of [tex]f(x) = 7^x[/tex] which stretched vertically by a factor of five is [tex]g(x) = 5(7^x)[/tex]

The length of the rectangle is twice the width. Find the length of the rectangle if the perimeter is 42m.
Answer:
28m
Step-by-step explanation:
2x+x=42
3x=42
x=14
However, since the length of the rectangle is twice the width, we'll need to multiply it by 2.
So: 14 times 2=28

Find the equation of the line that is perpendicular to the given line and passes through the given point.
y = −1/2x − 3; (14, 0)
The equation is y = ?
Answer:
[tex]y=2x-28[/tex]
Step-by-step explanation:
Slope intercept form:
[tex]y=mx+b[/tex]
where:
m is the slope (change in the y values over the change in the x values)b is the y-intercept (where x is 0)x and y are corresponding coordinate points (x,y)When two lines are perpendicular, their slopes will be opposite reciprocals.
examples:
[tex]\frac{1}{3}[/tex] → flip the fraction and change the sign → [tex]-3[/tex]
-5 or [tex]-\frac{5}{1}[/tex]→ flip the fraction and change the sign → [tex]\frac{1}{5}[/tex]
[tex]\frac{5}{7}[/tex] →flip the fraction and change the sign →[tex]-\frac{7}{5}[/tex]
So find the opposite reciprocal of the given slope:
[tex]y=(slope)x+(y-intercept)\\\\y=-\frac{1}{2} x-3\\\\slope=-\frac{1}{2}[/tex]
Flip the fraction and change the sign:
[tex]-\frac{1}{2}[/tex] → [tex]\frac{2}{1}[/tex] or [tex]2[/tex]
Now insert the new slope and the given points into point-slope form:
[tex]y-y_{1}=m(x-x_{1})\\\\(14_{x_{1}},0_{y_{1}})\\\\y-0=2(x-14)[/tex]
Solve the equation for y. Use the distributive property:
[tex]y-0=2(x)+2(-14)\\\\y-0=2x-28[/tex]
Simplify:
[tex]y=2x-28[/tex]
:Done
2 Write the equation of the line that goes
through (-2, 4) and is parallel to the line y = 1/2 x + 2
hi
if the twi lines are parallel , they have the same slope.
So slope is 1/2.
equation of a line is : mx +p
The line goes throught (-2 ; 4)
We have 1/2 ( -2) + p = 4
- 2/2 +p = 4
-1 +p = 4
p = 4+1
p = 5
equation of the line is y = 1/2x +5

can you guys help with these questions??
Answer:
Step-by-step explanation:
<3 = 55° ( vertically opposite angles )
<4 = 180 - 105 = 75° ( linear pair )
<5 = 180 - ( 55 + 75 ) ( angle sum property of a triangle )
= 180 - 130
= 50°
<1 = <2 ( angles opposite to equal sides )
let < 1 and < 2 be x
55 + 2x = 180 ( angle sum property of a triangle )
2x = 180 - 55
2x = 125
x = 125 / 2
x = 62.5
therefore, < 1 = <2 = 62.5°

In an asteroid field, 75% of the asteroids are carbonaceous asteroids. There are 375,000 carbonaceous asteroids in the asteroid field. How many asteroids are not carbonaceous? Asteroids are not carbonaceous.
Given:
In an asteroid field, 75% of the asteroids are carbonaceous asteroids.
There are 375,000 carbonaceous asteroids in the asteroid field.
To find:
The number of asteroids that are not carbonaceous.
Solution:
Let the total number of asteroids be x.
According to question,
[tex]75\%\text{ of }x = 375000[/tex]
[tex]\dfrac{75}{100}x=375000[/tex]
[tex]0.75x=375000[/tex]
Divide both sides by 0.75.
[tex]x=\dfrac{375000}{0.75}[/tex]
[tex]x=500000[/tex]
Asteroids not carbonaceous = Total asteroids - Carbonaceous asteroids
[tex]=500000-375000[/tex]
[tex]=125000[/tex]
Therefore, 125,000 asteroids are not carbonaceous.
