Step-by-step explanation:
When we multiply two intergers with the same sign, the product will be positive. When we multiply intergers with different signs, the quotient will be negative

What is the equation of the line that passes through the point (-7, 2) and has a
slope of -1
Answer:
y = -x - 5
Step-by-step explanation:
y = mx + b
slope = m = -1
y = -1x + b
y = -x + b
Plug in (-7, 2) for x and y, and solve for b.
2 = -(-7) + b
2 = 7 + b
b = -5
y = -x - 5
Find how much interest $10,000 earns in 2 years in a certificate of deposit paying 5.5% interest compounded quarterly.
The interest earned in 2 years is $__.
(Do not round until the final answer. Then round to the nearest cent as needed.)

A triangle has vertices A (0,0) B (2,6) and (0,4) Rotate it 180 clock wise about the origin followed by a dilation with a scale factor of 3 find the coordinates of the vertices of A’ B’ C’ and state whether the two triangles are congruent or similar
9514 1404 393
Answer:
A'(0, 0), B'(-6, -18), C'(0, -12)Step-by-step explanation:
Rotation 180° is the transformation ...
(x, y) ⇒ (-x, -y)
Dilation by a factor of 3 is the transformation ...
(x, y) ⇒ (3x, 3y)
The two transformations together can be described by ...
(x, y) ⇒ (-3x, -3y)
That is, the coordinates of A, B, C are each multiplied by -3. The image vertices are ...
A' = -3A = A'(0, 0) . . . . . . . . the center of rotation and dilation is invariant
B' = -3B = B'(-6, -18)
C' = -3C = C'(0, -12)
Any dilated figure will not be congruent to the original. The triangles are similar.

Please help now. I’m very confused and i don’t no how to do this. I don’t want just the answer but a great explanation.
Answer:
First option
Step-by-step explanation:
Hi there!
The "constant additive rate of change" means a constant slope.
The slope is [tex]\displaystyle\frac{change \hspace{4} in \hspace{4} y}{change \hspace{4} in \hspace{4} x}[/tex].
First of all, if the slope is constant, then we know immediately that it must be a linear function, a line. The change in y is forever the same according to the change in x. Knowing this, the second option is for-sure wrong (it's not a straight line).
Now, let's look at the first option. It is a linear function, which means it has a constant slope. However, we're given that the slope is [tex]-\displaystyle \frac{1}{4}[/tex]. This means that for a line, whenever it travels 4 units to the right, it travels 1 unit down (it travels down whenever the slope is negative and up whenever the slope is positive).
This is the exact case for the first option. Look at the point (-2,2) on the line. When we move 4 units to the right of that point, The line would have moved 1 unit down. We would reach the point (2,1).
Therefore, the correct answer would be the first option.
I hope this helps!

Step-by-step explanation:
Hi there!
Given;
f(x) = 5x-1
Now; Simply keep the value of x in the given function.
f(1) = 5*1-11
= -6
Again;
f(3) = 5*3-11
= 15-11
= 4
Therefore, f(1) = -6 and f(3) = 4.

Jacob took a total of 4 quizzes over the course of 3 weeks.
How many weeks of school will Jacob have to attend this quarter before he will have taken 16 quizzes?
Answer:
The answer would be a total of 12 weeks .
Step-by-step explanation:
Because the first four test were in a total of three weeks
so in order to find out how many weeks for 16 quizzes just multiply
4 quizzes -3 weeks
8 quizzes -6 weeks
12 quizzes - 9 weeks
16 quizzes - 12 weeks
SO just multiply 4 by 4 and multiply 4 by 3

6 + 5y - 4y + 10 + 3x - X
Answer:
2 + + 1 6
Step-by-step explanation:
Add the numbers:
6 + 5y - 4y + 10 + 3x -x =
1 6 + 5 − 4 + 3 −
Combine like terms:
16 + 5y - 4y +3x - x
16+ 1y + 3x -x
Multiply by 1
16 + 1y + 3x - x
16 + y + 3x - x
Combine like terms:
16 + y + 3x - x
16 + y + 2x
Rearrange terms:
16 + y + 2x
2x + y + 16
Answer:
16 + y + 2x
Step-by-step explanation:
[tex]6 + 5y - 4y + 10 + 3x - x[/tex]
[tex]16 + 5y - 4y + 3x - x[/tex]
[tex]5y - 4y = (5 - 4)y = 1y = y[/tex]
[tex]16 + y + 3x - x[/tex]
[tex] = 16 + y + 2x[/tex]
Find all of the points of the form (x, −x) which are 7 units from the origin.
(x, y) =
(smaller x-value)
(x, y) =
(larger x-value)
Answer:
(-7, 0) and (7, 0)Step-by-step explanation:
All the points that are 7 units from the origin are on the circle:
x² + y² = 7²The maximum and minimum values of x obtained when y = 0:
x² = 7² √x² = √7²x = ± 7So
min x = -7 and max x = 7The points are:
(-7, 0) and (7, 0)The equation will be
[tex]\\ \sf\longmapsto \sqrt{x^2+y^2}=7[/tex]
[tex]\\ \sf\longmapsto x^2+y^2=7[/tex]
If y be 0[tex]\\ \sf\longmapsto x^2+0=7^2[/tex]
[tex]\\ \sf\longmapsto x^2=49[/tex]
[tex]\\ \sf\longmapsto x=\sqrt{49}[/tex]
[tex]\\ \sf\longmapsto x=\pm 7[/tex]
Now the points are
(7,0)(-7,0)Find the values of the trigonometric functions of t from the given information. sec(t) = 2, terminal point of t is in Quadrant IV
Answer:
The values of the trigonometric functions of t
[tex]$\sin t=-\frac{\sqrt{3} }{2}[/tex]
[tex]\cos t=\frac{1}{2},[/tex]
[tex]\tan t=-\sqrt{3}[/tex]
[tex]$\csc t-\frac{2}{\sqrt{3} }[/tex]
[tex]\sec t=2[/tex]
[tex]\cot t=\frac{1}{\sqrt{3} }[/tex]
Step-by-step explanation:
Given:
[tex]\sec(t)=2[/tex]
The terminal point of [tex]t[/tex] is in Quadrant [tex]IV[/tex]
Step 1:
To find the values of trigonometric functions of t
[tex]\sec(t)=\frac{H}{A}[/tex]
[tex]=\frac{2}{1}[/tex]
Analyze the figure and find the value of O
[tex]t[/tex] ∈ [tex]IV[/tex]
[tex]O=\sqrt{2^{2}-1^{2} }[/tex]
[tex]=\sqrt{4-1}[/tex]
[tex]=\sqrt{3}[/tex]
Step 2:
[tex]$\sin t=-\frac{O}{H}[/tex]
[tex]=-\frac{\sqrt{3} }{2}[/tex]
[tex]\cos t=\frac{A}{H}[/tex]
[tex]=\frac{1}{2}[/tex]
[tex]\tan t=-\frac{O}{A}[/tex]
[tex]=-\sqrt{3}[/tex]
[tex]$\csc t=-\frac{H}{O}[/tex]
[tex]=-\frac{2}{\sqrt{3} }[/tex]
[tex]\sec t=\frac{H}{A}[/tex]
[tex]=\frac{2}{1}[/tex]
[tex]\cot t=-\frac{A}{O}[/tex]
[tex]=\frac{1}{\sqrt{3} }[/tex]
