Answer:
x = 14
Step-by-step explanation:
These angles are complementary angles, meaning they have a sum of 90°.
4x + 1 + 2x + 5 = 90
6x + 6 = 90 (Added like terms.)
6x = 84 (Subtracted 6 on both sides.)
x = 14 (Divided 6 on both sides.)
[tex]\sf \longmapsto \: (4x + 1) + (2x + 5)[/tex]
It has a sum of 90 as the given angles are complementary angles.[tex]\sf \longmapsto \: 4x + 1 + 2x + 5 = 90[/tex]
[tex]\sf \longmapsto4x + 2x + 1 + 5 = 90[/tex]
[tex]\sf \longmapsto6x + 6 = 90[/tex]
[tex]\sf \longmapsto6x = 90 - 6[/tex]
[tex]\sf \longmapsto \: 6x = 84[/tex]
[tex]\sf \longmapsto \: x = \cancel\dfrac{84}{6} [/tex]
[tex]\sf \longmapsto \: x = 14[/tex]

What is the equation of a line parallel to -5x + y= 2 that passes through the point with coordinates (-2,1)?
Answers
Answer:
y=5x+11
Step-by-step explanation:
You can solve this with the point-slope formula: y-y1=m(x-x1). The line is parallel; both slopes are equivalent.
First we have to rewrite the original equation, which is rewritten into y=5x+2 by subtracting -5x on both sides.
Next, plug in the coordinates we have into the point-slope formula (-2, 1), along with the slope from the original equation (5). To check, we can plug the coordinates back into the equation.
y-(1)=5(x+2)
y-1=5x+10
y=5x+11
Check:
(1)=5(-2)+11
1=-10+11
1=1

Can someone help me with this graph? I don't understand how to solve it
Answers
X+y=-5
-x -x
y=-x-5 is the ending equation.
How to graph:
The y-intercept, or point where the graph starts, is -5
From there go down 1, right 1.
M=-x
B=-5
Answer: m = -1 b = -5
Step-by-step explanation:
Rewrite the equation in "slope-intercept form" y = mx +b .
m is the slope
b is the y-intercept, where the graph of the line crosses the y-axis
To rewrite the equation, to get "y" alone on the left side, subtract x from both sides:
x + y = -5
-x + x + y = -x - 5 (left side -x +x =0 so "cancel")
y = -x -5
You get the slope "m" from the coefficient of x, (invisible 1, sometimes)
since there is a negative sign, the coefficient is -1 That is m, the slope.
A negative slope goes down from left to right.
For -1, down one over 1 square.
Your graph should look like the screenshot below.
I hope this helps you understand better!

The equation 3x =y models the relationship between jellyfish, and sea turtles such that the ratio of their numbers remain constant.
What is ratio?Ratio is the relationship between two numbers given by a quotient
If the ratio of two numbers x and y is x/y then the fraction x/y gives that what parts x is of y .
Given that there are 4 sea turtle and 12 jellyfish in the sea when Alex counted the number.
Ratio of number of sea turtle to number of jellyfish = 4/12 = 1/3
Let at any time the number of sea turtles be x and number of jellyfish be y
Then ratio of number of sea turtles to jellyfish = x / y
Given that this ratio remained constant during the remainder of his dive,
∴ x/y = 1/3
Cross multiply
⇒ 3x = y
The equation that models the relationship between jellyfish, and sea turtles is 3x =y

-5a + 15/2a - 25 = 53.2 + 21.8
Answers
Answer:
a= 40
Step-by-step explanation:
-5a + 7.5a - 25 = 53.2 + 21.8
add like terms on both sides: 2.5a - 25 = 75
add 25 on both sides: 2.5a = 100
divide both sides by 2.5: a = 40
Answer:
a = 40
Step-by-step explanation:
-5a + 15/2a - 25 = 53.2 + 21.8: Add 25 to Isolate variable
-5a + 15/2a = 53.2 + 21.8 + 25: Combine Like Terms and create simmilar terms
-10/2a + 15/2a = 100: CLM again
5/2a = 100: multiply both sides by inverse of 5/2 to isolate variable
a = 40

Step-by-step explanation:
Answer:
(2, 2 2/5)
Step-by-step explanation:
(0, 2/5) is correct, and since the slope is 1, adding any number to both the x and the y would still make it a solution.
In this case, you could add 2 to both x and y, resulting in (2, 2 2/5).
