Step-by-step explanation:
if ∠WXY = 90°, then XY is tangent to circle Z
test using Pythagorean theorem:
WX = 2(ZX) = 17
is 20² = 5² + 17²?

Help Y+7=1/2(12x+8) I need help guys
Answer:
A. y=6x-3
B. The slope is 6
C. y-intercept is -3
E. y-6x= -3
F. (1/2, 0)
Step-by-step explanation:
I can't do the graph because I don't know how to input a picture but I hope this helped!
This is for the second half of the page:
2. the slope of y=3 is 0 so m=0
to graph just draw a line horizontally at 3
3. the equation of the line is x=2
the slope of this line undefined, so literally just write undefined
4. y= -6/7x-1
Brian was thinking of a number . Brian doubles it and gets an answer of 93.3.what was the original number?
Answer:
The answer is 49.65
Step-by-step explanation:
99.3 divided by 2 gives you the answer.
Answer:
46.65
Step-by-step explanation:
All you have to do is the reverse of what he did, so here he multiplied his number by 2 so we divide by to get the original number.

Algebra.
1. A
Since parallel lines never cross, then there can be no intersection; that is, for a system of equations that graphs as parallel lines, there can be no solution. This is called an "inconsistent" system of equations, and it has no solution.
--------------------------------------------------------------------------------------------------------------
2. C
That's right. If a system of equations has a solution, then their graphs intersect, and the point where they intersect is the solution because it's the point that satisfies each equation in the system.
Straight-line graphs with the same slope are parallel lines, and they never intersect, which is another way of saying they have no solution.

In ΔBCD, the measure of ∠D=90°, the measure of ∠B=71°, and DB = 67 feet. Find the length of BC to the nearest tenth of a foot.
Answer:
BC = 205.8 feet
Step-by-step explanation:
Please see attached photo
From the attached photo:
Angle B = 71°
Adjacent = BD = 67 feet
Hypothenus = BC = x
The value of x can be obtained as follow:
Cos B = Adjacent / Hypothenus
Cos 71 = 67 / x
0.3256 = 67 / x
Cross multiply
0.3256 × x = 67
Divide both side by 0.3256
x = 67 / 0.3256
x = 205.8 feet
Therefore BC = 205.8 feet

Las edades de cuatro hermanos forman una progresión aritmética, y su suma es 32 años. El mayor tiene 6 años más que el menor. Halla las edades de los cuatro hermanos.
Answer:
The ages of the four siblings are: 5, 7, 9 and 11 years old.
Step-by-step explanation:
The computation of the age of the four siblings is shown below:
Given that
n = 4
a1 =? a2 =? a3 =? a4 =?
a4 = a1 + 6 years
S4 = 32
Based on the above information
As we know that
Sn = (a1 + a4) × n ÷ 2
S4 = (a1 + a4) × 4 ÷ 2
32 = (a1 + a1 +6) × 2
16 = 2a1 + 6
2a1 = 10
a1 = 10 ÷ 2
= 5
So, a4 = a1 +6
= 5 +6
= 11
a4 = a1 + (4-1) × d
11 = 5 + 3 × d
d = 6 ÷ 3
= 2
So,
a2 = a1 + d
= 5 + 2
= 7
a3 = a2 + d
= 7 + 2
= 9
Hence, The ages of the four siblings are: 5, 7, 9 and 11 years old.

Which of these worms has bristles, called setae, on its soft body to help it move?
nematodes
earthworms
roundworms
flatworms
Answer:
earthworm
Step-by-step explanation:
The worm which hasbristles, called setae, on its soft body to help it move is roundworm, the correct option is roundworm.
what are worms?Worms are described as many different distantly related bilateral animals that typically have a long cylindrical tube-like body, no limbs, and no eyes. Roundworms constitutes of the phylum Nematoda, with plant-parasitic nematodes also known as eelworms.
Given;
The worms has bristles, called setae
Now,
Roundworm infections usually occur when soil, sand, or plants that have been contaminated with infected animal feces are accidentally put in the mouth and ingested by individuals;
Therefore, the worm will be roundworm.

Find the complement and the supplement of the given angle.
23°
Answer:
Complement: 67°
Supplement: 157°
Step-by-step explanation:
Complementary angles = 90°
90-23=67°
Supplementary angles = 180°

HI PLEASE HELP I WILL GIVE BRAINLEIST
PLEASE SHOW ME THE WORKINGS
Answer:
see explanation
Step-by-step explanation:
Expand the factored form and compare coefficients of like terms with the original polynomial
a(x + 1)(x - 2)² + b(x + 2) + c
= a(x + 1)(x² - 4x + 4) + b(x + 2) + c
= a(x³ - 4x² + 4x + x² - 4x + 4) + b(x + 2) + c
= a(x³ - 3x² + 4) + b(x + 2) + c ← distribute parenthesis
= ax³ - 3ax² + 4a + bx + 2b + c
Compare x³ terms
ax³ with 2x³ , then a = 2
Compare x terms
bx = - 3x , then b = - 3
Compare constant terms
4a + 2b + c = 6
4(2) + 2(- 3) + c = 6
8 - 6 + c = 6
2 + c = 6 ( subtract 2 from both sides )
c = 4
Thus a = 2, b = - 3, c = 4
