Which equation is an identity
write an equation for the line that is parellel to the given line and that passes through the given point?
y = 2x + 7; (3, 11)
a.y = 2x – 19
b.y=1/2x+5
c.y= -1/2x-5
d.y = 2x + 5
Answer:
y = 2x + 5 (answer d)
Step-by-step explanation:
Parallel lines have the same slope, and thus, if we're given y = 2x + 7, we know that the slope of the 'new' line is 2. This 'new line' passes through (3, 11). Begin with the point-slope formula y - k = m(x - h) and substitute 3 for h, 11 for k and 2 for m:
y - 11 = 2(x - 3)
Rewriting this in slope-intercept form, we get:
y = 2x - 6 + 11. or y = 2x + 5 (answer d)

Answer:
9. C, II and III.
10. The correct answer is 944 cubic mm, as far as I can tell. I double checked my formulas and calculations. You can copy the formulas/calculations below and email your teacher. I have tried to figure out how they got the numbers they have. The best guess I can come up with is that they used 6 as the diameter of the cylinder, using 3 for the radius. That gets us closer, at 749 cubic mm, but not quite there.
Step-by-step explanation:
9. If the cylinder is standing upright, the horizontal cut would be a circle or oval, and the vertical cut could be a rectangle
10. First we'll get the volume of the base rectangle. Then we'll calculate the volume of a cylinder, then divide that part in half, because it's 1/2 a cylinder on top of a rectangular prism.
Volume of a rectangular prism:
V = (length)(width)(height)
= 11 x 9 x 6 = 594 cubic mm
Volume of a cylinder:
V = (pi)(radius)^2(height)
The radius = 1/2 the diameter of the circle...the diameter is 9, so the radius is 4.5
= (3.14)(4.5)(4.5)(11)
= 699.435
That would be for a full cylinder with radius 4.5 and height of 11. We have half of one, so 699.435/2 = 349.7175 cubic mm
Add the volume of the 1/2 cylinder to the volume of the rectangular prism:
349.7175 + 594 = 943.7175, rounded = 944...which is none of your answers :/
Sorry I couldn't give you an "A, B, C, D" answer, but I don't think any of those are correct.
5. If f (x) = -4x + 7. what is:
a. f(0)
b. f(-2)
c. Write part (a) & (b) as ordered pairs.
Answer:
f(0) = 7 f(-2) = 15 (7,15)
Step-by-step explanation:
f(0) = -4(0) + 7 = 7
f(-2) = -4(-2) + 7 = 15
(7,15)

Answer: The total of all side lengths must equal 180 degrees
Step-by-step explanation:
if you take 180-100=80 then you have the two missing angles, divide 80 by 2 and you get 40 so 1 x measurment equals 40 degrees

Work out size of Angle x
Answer:
106
Step-by-step explanation:
all 3 of the angles add up to 360
you already know one is 164 and one is a right angle so
164 + 90 = 254
360 - 254 = 106
Devin is making a candle by pouring melted wax into a mold in the shape of a square pyramid. Each side of the base of the pyramid is 6 cm and the height of the pyramid is 9 cm. To get the wax for the candle, Devin melts cubes of wax that are each 4 cm by 4 cm by 4 cm. How many of the wax cubes will Devin need in order to make the candle? Show your work.
The volume of the square pyramid is 6 x 6 x 9/3 = 108 cubic cm.
Volume of the cube = 4 x 4 x 4 = 64 cubic cm
Number of cubes needed: 108/64 = 1 11/16 cubes (1.6875)
Answer:
Solution given:
square pyramid
each side of base[b]=6cm
height[h]=9cm
Volume of square pyramid[V]=[tex] \frac{1}{3 } {b}^{2} h \\ \frac{1}{3} {6}^{2} \times 9 = 108cm ^{3} [/tex]
now
length of cube [l]=4cm
volume of cube[v]=l³=4³=64cm³
now
no of wax needed=[tex] \frac{V}{v} [/tex]=[tex] \frac{108cm³}{64cm³} [/tex]=[tex] \frac{27}{16 } =1\frac{11}{16} [/tex]

Answer:
"so i need to find e missing side of each right triangle, side c is the hypotenuse!! a = 8.8ft, b= 9ft i have to round the answers to the nearest tenth if necessary "
Step-by-step explanation:
Sure! So remember that the Pythagorean theorem is a squared plus b squared = c squared.
= 8.8 squared + 9 squared = c squared
= 77.44 + 81 = c squared
[tex]\sqrt{158.44}[/tex] = c squared
c squared = (rounded) 12.6 ft

A man travels 2 miles, turn left and travels 3 miles, turn left again and travel 6 miles. How far is he from the starting point?
Answer: 5 miles
Step-by-step explanation:
this creates a polygon which can be shortened to be a triangle with side lengths 3 and 4 and the hypotenuse unknown. to find the side length you use the formula a^2 + b^2 = c^2
3^2 + 4^2 = c^2
9 + 16 = c^2
25 = c^2
sqrt(25) = c
c = 5
