Answer:
(-7,-3)
Step-by-step explanation:
You keep the -3 since that is the y but the x will become negative because you are reflecting to the left and not the right, making the x then negative.
Answer: (-7,-3)
Step-by-step explanation:
The point (7,-3) is located in the fourth quadrant mean that if you reflect the point across the y a-xis, it should end up in the third quadrant.
If you flip a point over the y axis, the x coordinate switches.
(7,-3) ⇒ (-7,-3)

A breakfast menu liste 3 eggs with 2 sausage for $4.15 or 4 eggs with 1 sausage for $4.30 . What is the cost of 1 egg, and what is the cost for 1 sausage?
Answer:
Cost of 1 egg = x = $0.89
Cost of 1 sausage = y = $0.74
Step-by-step explanation:
Let the:
Cost of 1 egg = x
Cost of 1 sausage = y
A breakfast menu lists:
3 eggs with 2 sausage for $4.15
3x + 2y = 4.15......Equation 1
4 eggs with 1 sausage for $4.30 .
4x + y = 4.30...... Equation 2
y = 4.30 - 4x
We substitute 4.30 - 4x for y in Equation 1
3x + 2(4.30 - 4x) = 4.15
3x + 8.6 - 8x = 4.15
3x - 8x = 4.15 - 8.6
-5x = -4.45
x = -4.45/-5
x = $0.89
Solving for y
y = 4.30 - 4x
y = 4.30 - 4(0.89)
y = 4.30 - 3.56
y = $0.74
Therefore,
Cost of 1 egg = x = $0.89
Cost of 1 sausage = y = $0.74
Which graph has a y-intercept of -1/2?
Answer:
C.
Step-by-step explanation:
Y-intercept basically means where on the graph does the line "cut" through the y-axis (the vertical line). In the graphs, there is only one line which cuts through the y-axis at -1/2, which is C. .

Ella buys 5 packs of muffins. She uses a coupon and saves $3 off the total. Which expression represents her total cost?
A. 5m -3
B. 5 -3m
C.5+3
D. 5m + 3
Answer:
The answer is A. 5m - 3
Step-by-step explanation:
Ella bought 5 packs of muffins but since we don't know how many muffins are in each pack, we put a variable in place so it's 5m. Since she saved $3 off the total, that means you would subtract 3 from the total, so the problem would be 5m - 3
ZX and zy or supplementary angles. zy measures 49 degrees what is the measure of ZX
Answer:

Posted this question 1000times. Plz some answer plz plz i beg. Plz show all working, thank you sir
Answer:
[tex]\approx 26.16\:\mathrm{m}[/tex]
Step-by-step explanation:
Let [tex]h[/tex] be the height of the tree. In reference to the tree and bird, a right triangle is formed. We can write the following trig function for that right triangle:
[tex]\tan28^{\circ}=\frac{h}{15},\\h=15\tan28^{\circ},\\h\approx 7.98\:\mathrm{m}[/tex].
Now we can use this to find the hypotenuse of this triangle (the distance between the cat and the bird):
Let the distance between the cat and bird be [tex]k[/tex]. Then,
[tex]7.98^2+15^2=k^2,\\k\approx 16.99\:\mathrm{m}[/tex]. This is one side of the triangle that is formed by the cat, bird, and mouse.
The right triangle formed by the tree, cat, and mouse shares the height [tex]h[/tex] with the other right triangle, as we found earlier. Let [tex]l[/tex] represent the hypotenuse of this triangle or the distance between the cat and mouse. We then have the following trig function:
[tex]\sin 40^{\circ}=\frac{7.98}{l},\\l=\frac{7.98}{\sin40^{\circ}}\approx 12.41\:\mathrm{m}[/tex]. This is another side of the triangle that is formed by the cat, bird, and mouse.
The triangle that is formed by the cat, bird, and mouse has shares an angle of [tex]125^{\circ}[/tex] with the base of the auxiliary pyramid. The other angles, however, are not shared.
Since we have two sides and the angle between these two sides, we can use the Law of Cosines to find the other side (the distance between the mouse and bird). The Law of Cosines is given by:
[tex]m^2=k^2+l^2-2kl\cos M[/tex], where [tex]m[/tex] is the distance between the bird and the mouse and the other variables are defined above.
Plugging in values, we get:
[tex]m^2=16.99^2+12.41^2-2\cdot16.99\cdot12.41\cdot\cos 125^{\circ}[/tex]
Solving, we get:
[tex]m\approx \fbox{$26.16\:\mathrm{m}$}[/tex].

Hey there!
According to the question, you need to find out the distance from your friend's house to school.
Firstly figure out the coordinate of your school and school. Then use formula of distance.
So, we find the coordinates as (7,7) and (5,0).
So, x 1 = 7 y1= 7
x 2 = 5 y2 = 0
~ Use distance formula.
[tex]d = \sqrt{( {x2 - x1)}^{2} + ( {y2 - y1)}^{2} } [/tex]
~ Put all values.
[tex]d = \sqrt{ {(5 - 7)}^{2} + ( {0 - 7)}^{2} } [/tex]
~ Simplify it.
[tex]d = \sqrt{ {( - 2)}^{2} + {( - 7)}^{2} } [/tex]
[tex]d = \sqrt{4 + 49} [/tex]
[tex]d = \sqrt{53} [/tex]
D= 7.280
Therefore, the distance between your friend's house and your school is 7.3 units.
Hope it helps....

y = a + x
y = 1 X
y = 4 + x
y = 4x
Answer:
The equation of the graph is;
y = 4·x
Step-by-step explanation:
The coordinates of two points, (x₁, y₁), and (x₂, y₂) respectively on the straight line graph are;
(-3, 12), and (2, 8)
The slope, m, of the straight line graph is given as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Therefore, by substitution of the values, we have;
[tex]Slope, \, m =\dfrac{8-(-12)}{2-(-3)} = \dfrac{8 + 12}{2 + 3} =\dfrac{20}{5} = 4[/tex]
The equation of the graph in point slope form is therefore;
(y - 8) = 4×(x - 2)
y = 4·x - 8 + 8 = 4·x
y = 4·x.

4x − 3 = 21
Answer:
First one is 4x = 24
Second one is x = 6
This one is 6
Answer:
Add 3 to both sides of the equation:
4x − 3 + 3 = 21 + 3
4x = 24
Divide both sides of the equation by 4:
4x/4 = 24/4
x = 6
The number line represents x-values, so the solution is at 6.

find the total surface area of the triangular prism
Answer:
[tex]1,008\:\mathrm{cm^2}[/tex]
Step-by-step explanation:
The total surface area of this triangular prism consists of three rectangles and two triangles. Adding the areas of each of these shapes allows us to find the total surface area of this 3D figure:
Area of both triangles:

Answer:
angle v equals 75.8 degrees
Step-by-step explanation:
since the lines parallel, then angle u and angle v would be the same as they are alternate interior angles. you can also subtract 180 with angle w to find angle v as well (180 - 104.2 = 75.8)

The slope formula can be used to find the slope, m, of a line with points (L1, y1) and (22, 42).
Y2 - Yi
22 - 21
m
Which is an equivalent equation?
O Y1 = -m (22 – x1) + y2
yı = -m (x2 – 21) – Y2
Oyı = m (22 – 21) + y2
Oyı = m (22 – 21) – Y2
Answer: [tex](y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)[/tex]
Step-by-step explanation:
Point slope form: [tex](y-b)=n(x-a)[/tex] , where n=slope , (a,b) is the point through which line passes.
If slope of the line = m and line passes through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] :-
[tex](y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)[/tex]
So, the equivalent equations are :
[tex](y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)[/tex]
