Answer:
x=-35/6
Step-by-step explanation:
2 + 3( 4x + 5) = -53
subtract 2 from both sides= 3(4x+5)=-55
divide both sides by 3 = 4x+5=-55/3
subtract both sides by 5 = 4x=-70/3
divide both sides by 4 = x=-35/6
x=-35/6 is your final answer
Answer:
Hope this helps :)
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:
x=−35/6
Decimal Form:
x=−5.8¯3 (Repeating)
Mixed Number Form:
x=−5 5/6
work out the equation of a line which has a gradient of -2 and passes through the point (1 ,7)
Answer:
Y=-2x+9
Step-by-step explanation:
The first thing is to know the formula which is Y÷x
Then... The line (1,7)use the coordinates Y and X so it will be as follows... Label 1 and 7 as x, y
So it will be Y-7÷X-1 = the gradient which is - 2
So multiply both sides by X-1
So it will be Y-7=2x+2 again be careful because a negative number multiplied by another negative will give you a positive sign
Remember Y-7....... Take 7 to the other side so it will be a positive...... Then work out the integers

Which translation takes y = | x + 2 | - 1 to y = | x | + 2 ?
Select one:
a. 2 units left, 3 units down
b. 2 units left, 3 units up
c. 2 units right, 3 units up
d. 2 units right, 3 units down
(Solve by graphing and determining the translation. Thanks in advance!)
Answer:
C
Step-by-step explanation:
y = | x + 2 | − 1 has a vertex at (-2, -1).
y = | x | + 2 has a vertex at (0, 2).
So the graph is translated 2 units right and 3 units up.
-5x+2y=9
y=7x
I need help with in the next 10 minutes I will give brainiest!!!!!
Answer:
x = 1 and y = 7
Step-by-step explanation:
First, you substitute the y into the first equation
-5x+2(7x)=9
-5x+14x=9
9x=9
x=1
Then put the x into the equation to find y
This is if you substitute using the second equation

An equilateral triangle with side lengths of 7 units is translated 3 units to the right. What is the length of one side of the triangle after the translation, in units? 3 units
Answer:
[tex]Sides= 7\ units[/tex]
Step-by-step explanation:
Given
[tex]Sides= 7\ units[/tex]
[tex]Translation = 3\ units[/tex] (to the right)
Required
Determine the length of one side after translation
It should be noted that when a shape, line, object is being translated by shifting its position, only the position of the shape, line or object changes not its length
This implies that, the length of the sides of the equilateral triangle remain unchanged.
Hence:
[tex]Sides= 7\ units[/tex]

Consider the equation 5x^2-10x+c=0. What values of c result in the equation having a complex solutions? Represent your answer on the number line
Answer:
When we have a quadratic equation:
a*x^2 + b*x + c = 0
There is something called the determinant, and this is:
D = b^2 - 4*a*c
If D < 0, then the we will have complex solutions.
In our case, we have
5*x^2 - 10*x + c = 0
Then the determinant is:
D = (-10)^2 - 4*5*c = 100 - 4*5*c
And we want this to be smaller than zero, then let's find the value of c such that the determinant is exactly zero:
D = 0 = 100 - 4*5*c
4*5*c = 100
20*c = 100
c = 100/20 = 5
As c is multiplicating the negative term in the equation, if c increases, then we will have that D < 0.
This means that c must be larger than 5 if we want to have complex solutions,
c > 5.

one number is nine more than another number, if the sum of the number is 65, find both numbers
Answer:
28 and 37
Step-by-step explanation:
Answer:
28 and 37
Step-by-step explanation:
This is very simple actually!
First subtract the 9:
65 - 9 = 56
Then divide by 2:
56 ÷ 2 = 28
28 is one of your answers. If we want to find the other one, then add back 9
28 + 9 = 37
That's it!

Which graph represents a function
Kerry is looking foward to a skiing trip this weekend she checked the tempature yesterday and today, and overnigjt is dropped from 12 F to -5 F what is the total difference in the tempature
Answer:
-[tex]17^\circ F[/tex]
OR
[tex]17^\circ F[/tex] decrease in the temperature.
Step-by-step explanation:
Given that:
Temperature at the night = [tex]12^\circ F[/tex]
Temperature in the morning = -[tex]5^\circ F[/tex]
To find:
The total difference in the temperature = ?
Solution:
Difference of any quantity is given by the Final value of quantity minus Initial value of quantity.
Therefore, the difference is given as : -[tex]5^\circ F[/tex] - [tex]12^\circ F[/tex] = -[tex]17^\circ F[/tex]
Negative value in the difference indicates that there is a decrease of the quantity.
So, the answer is:
-[tex]17^\circ F[/tex]
OR
there is decrease of [tex]17^\circ F[/tex] in the temperature.
Find the measure of each numbered angle
The measure of each numbered angles are ∠1 = 56°, ∠2 = 56° and ∠3 = 74°.
What is Angle?An angle for any figure is formed by two rays which joins at a common point called vertex or node.
Usually angles are measured in degrees or radians.
Consider triangle PMQ
The sum of the interior angles of a triangle is 180°.
∠MPQ + ∠QMP + ∠PQM = 180°
58° + 66° + ∠1 = 180°
∠1 = 180° - (58° + 66°)
∠1 = 180° - 124°
∠1 = 56°
Now, ∠1 and ∠2 are vertically opposite angles. Hence they are equal.
∠2 = 56°.
Again, for triangle NQO
∠2 + ∠3 + 50° = 180°
56° + ∠3 + 50° = 180°
∠3 = 180° - (50° + 56°)
∠3 = 180° - 106°
∠3 = 74°
Hence ∠1, ∠2 and ∠3 are 56°, 56° and 74° respectively.

What is simplification?To simplify means to make anything easier. In mathematics, simplifying an equation, fraction, or problem means taking it and making it simpler. Calculations and problem-solving techniques simplify the issue. By eliminating all common factors from the numerator and denominator and putting the fraction in its simplest/lowest form, we can simplify fractions.
Given equation
(n + 8) + (n − 12) =
n + 8 + n - 12
solving constant separately and variables separately,

2x + 4y-31=123 what is the equation for x and then y
Answer:
i would say
y = ( 77 - x ) / 2
Step-by-step explanation:
2x + 4y = 123 + 31
2x +4y = 154
4y = 154 -2x
y = ( 154 - 2x ) / 4
y = ( 77 - x ) / 2
