(hope this helps)
Answer:
[tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
"The sum of 8 times a number (x) and 7 equals 3."
Let, "a number" = x
8x + 7 = 3
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and equals:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction.
First, subtract 7 from both sides of the equation:
8x + 7 (-7) = 3 (-7)
8x = 3 - 7
8x = -4
Next, divide 8 from both sides of the equation:
(8x)/8 = (-4)/8
x = -4/8
x = -1/2
-1/2 is your number, or -0.5

for which would you draw a dashed boundary line a d shade to the left?
a) x⩽ -4
b) x ⩾ -4
c) x < -4
d) x > -4
Answers
Answer:
a) x⩽ -4
Step-by-step explanation:
This is because the required region is anything to the left of -4 that is x < -4. Now since x = -4 is inclusive, we have the inequality x ≤ -4.
We thus draw a dashed boundary line to represent the equality at the boundary for x ≤ -4.
Since that is done, we then shade to the left of the boundary line which is the required region of x ≤ -4.

To find slope you would use the slope formula of (y2-y1)/(x2-x1). This gives us the slope of -5/4. Then we find the y-intercept. When looking on the graph we see the only y intercept is the point (0,3), so we get the number 3.

The new coordinates are:
A' (6, 24)B'(12, 12)C'(-12, 6)Please check the attached graph.
Step-by-step explanation:
We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.
If the scale factor > 1, the image is enlarged
If the scale factor is between 0 and 1, it gets shrunk
If the scale factor = 1, the object and the image are congruent
Given the vertices of the triangle in the diagram
A (1, 4)
B(2, 2)
C(-2, 1)
In our case:
Scale Factor K = 6Rule to calculate the dilation by a scale factor 6 centered at the origin
P(x, y) → P'(6x, 6y)
Here, P'(6x, 6y) ) is the image of P(x, y).
It means the coordinates of the image can be determined by multiplying the coordinates of the original point by 6.Thus,
A (1, 4) → A'(6(1), 6(4)) → A'(6, 24)
B(2, 2) → B'(6(2), 6(2)) → B'(12, 12)
C(-2, 1) → C'(6(-2), 6(1)) → C'(-12, 6)
Therefore, the new coordinates are:
A' (6, 24)B'(12, 12)C'(-12, 6)Please check the attached graph.
