The slope of a line parallel to another line must have the same slope as the other line. So therefore, we just want to first find the slope of this line.
To do this, we can switch it to slope intercept form, which is y = mx + b.
-2y = -5x + 11
Notice that the y doesn't have a variable next to it in slope intercept form. This means you have to divide all the sides to -2 to cancel out that -2.
-2y = -5x + 11
/-2 /-2 /-2
y = 5/2x + 11/-2
Since in the equation, y = mx + b, the number in the position of m = the slope, we know that 5/2 is the slope.
So therefore, the slope of a line parallel to the line with equation 5x - 2y = 11 must be 5/2.
Answer:
I think both angles are 95 degrees for question 14
Step-by-step explanation:
Because if you split the shape in half they make two triangles which is always the sum of 180 so all you do is add the two know angles together to get 128. Once you have that you would solve for your missing angles by subtracting 180 from 128 which gives you 95 degrees.
85+ m<b+ 43= 180 degrees goes for angle d to.
83+43=128
180-128=95
Now check work by plug in your answer.
85+95+43=180
180=180
making this a true statement.
Answer:
y = 3
y = 5
(last answer choice)
Step-by-step explanation:
A system of equation is given in "x" and "y".
For it to have a solution, there should be a value for x and a value for "y".
There needs to be 2 values, one for x and another for y.
It doesn't matter if the values of x and y are same, but there needs to be one value of x and one value of y (if linear equations).
First one has a value of x = 5 and y = 3, so there are 2 values, one for x and another for y, distinct values. So it's okay.
The second one has 2 values for x and y, respectively. THey are same, doesn't matter. So, this one is okay as well.
The last one has NO VALUE for x and has 2 values for y. So, this one doesn't have a proper solution.
So, the last one of the choices shown has NO SOLUTION.
Let x be the number of students in the class the
the number of students in the class when 1 in 4 are absent = x - 0.25x = 0.75x
After Jen returns there are x - 0.2x = 0.80x so we have the equation
0.75x + 1 = 0.80x
0.05x = 1
x = 1 / 0.05 = 20 Answer
So there are 20 students in the class.
No. students not here today = 0.80 * 20 = 16 Answer
Answer:
b = 8/3
b = 2 2/3
Step-by-step explanation:
3/4 b =2
Multiply each side by 4/3 to isolate b
4/3 * 3/4 b = 4/3*2
b = 8/3
b = 2 2/3
