Answer:
x=-4
Step-by-step explanation:
Divide 3 on both sides since you use the inverse to cancel out each other but you need to do it on both sides to make the equation balance.
3 divided by 3x is x
3 divided by -12 is -4
x=-4

DONE
What do the equations have in common and how are they different
Answer:
Slope -intercept for of equation 1: [tex]y=-2x+5[/tex]
Slope -intercept for of equation 2: [tex]y=-2x+3[/tex]
Looking at slope-intercept form of both equations, we have slope m = -2
Both have same slopes so, the lines are parallel.
Step-by-step explanation:
We need to write equations in slope-intercept form.
The general formula of slope-intercept form is: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
The first equation is:
[tex]2x+y=5[/tex]
Slope-intercept form:
[tex]y=-2x+5[/tex]
The second equation is: [tex]3y=9-6x[/tex]
Rearranging: [tex]3y=-6x+9[/tex]
Slope-intercept form:
[tex]y=\frac{-6}{3} x +\frac{9}{3}\\y=-2x+3[/tex]
Slope -intercept for of equation 1: [tex]y=-2x+5[/tex]
Slope -intercept for of equation 2: [tex]y=-2x+3[/tex]
Looking at slope-intercept form of both equations, we have slope m = -2
Both have same slopes so, the lines are parallel.
They have different y-intercepts.
What is the perimeter (please explain your answer)
Answer:
Answer: B. 38 mm
Step-by-step explanation:
The Perimeter of a Shape
The perimeter of a given shape is the sum of all exterior lengths surrounding the shape.
The figure shows a shape where all the external measures are given except the leftmost side.
This length is the sum of 3 mm + 10 mm = 13 mm.
Now calculate the perimeter:
P = 4 mm + 3 mm + 10 mm + 8 mm + 13 mm = 38 mm
Answer: B. 38 mm

PLEASE HELP!! The measure of angle 3 is 101 degrees. Find the measure of angle 4. ILL MAKE YOU BRAINLIEST.
Answer:
The answer is A aka 79*
Step-by-step explanation:
Based on the information given, the value of angle 4 will be 79°.
Solving angles.It should be noted that the sum of angles on straight line is always 180°.
In this case, the value of the other angle is 101°. Therefore, the value of angle 4 will be:
= 180° - 101°
= 79°

On a 6-sided number cube, which is more likely: rolling an odd number or rolling an even number?
Answer choices:
A) rolling an even number
B) the events are equally likely
C) neither is possible
D) rolling an odd number
Answer:
B
Step-by-step explanation:
Even numbers = 2,4,6
Odd numbers = 1,3,5
Same amount of numbers
Answer:
B. The events are equally likely.
Step-by-step explanation:
On a 6-sided number cube, there are 3 even numbers (2, 4, 6) and 3 odd numbers (1, 3, 5). There is a 1/2 (3 of 6) chance you will roll an even number, and a 1/2 chance you will roll an odd number. These chances are the same, so B is the answer.

What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
So, (3y + 32)° + 73° = 180°, as pair of the corresponding exterior and interior angle form 180°.
(3y + 32)° + 73° = 180°.
3y + 105° = 180°.
3y = 180° - 105°.
3y = 75°.
y = 25°.
We also know that vertically opposite angles are equal,
∴ (3y + 32)° = z°.
75° + 32° = z°.
z° = 107°.

Let f (x) = 3x2 + 2 and g(x) = 2x, find f (g(x))
Answer:
D) 12x^2+2
Step-by-step explanation:
As we are dealing with composite functions, the rule is that f(g(x)) means whatever the value of g(x) is, we substitute that value for x in f(x):
[tex]f(x)=3x^2+2\\g(x)=2x\\f(g(x))=3(2x)^2+2\\f(g(x))=3(4x^2)+2\\f(g(x))=12x^2+2[/tex]
So, f(g(x))=12x^2+2, making D the right answer

The ratio of girls to boys in a certain grade is 9;8. If there are 72 girls in the grade, how many boys are there?
Answer:
[tex]Boys = 81[/tex]
Step-by-step explanation:
Given
[tex]Boys : Girls = 9 : 8[/tex]
[tex]Girls = 72[/tex]
Required
Find the number of boys
Substitute 72 for girls in [tex]Boys : Girls = 9 : 8[/tex]
[tex]Boys : 72 = 9 : 8[/tex]
Convert ratio to fraction
[tex]\frac{Boys}{72} = \frac{9}{8}[/tex]
Multiply both sides by 72
[tex]72 * \frac{Boys}{72} = \frac{9}{8} * 72[/tex]
[tex]Boys = \frac{9}{8} * 72[/tex]
[tex]Boys = 9*9[/tex]
[tex]Boys = 81[/tex]
