Answers
Answer:
-21
Step-by-step explanation:
the y intercept is when x=0.
you can see that this is a linear equation where each increase in x results in an increase of 4 onto the y value.
so if when x=1, y=-17, subtract 4 to find what y equals when x is 0.
-17 -4=-21
good luck :)

Step-by-step explanation:
[tex]6x^{2} -4xy + 2y^{2} -5x^{2} +2xy+10xy[/tex]
Okay, so of course you need to add like terms. But where should you start? Well, [tex]6x^{2}[/tex] and [tex]-5x^{2}[/tex] are both like terms, so lets add them first.
[tex]6x^{2} -5x^{2} = x^{2}[/tex]
Also, [tex]-4xy[/tex], [tex]2xy[/tex], and [tex]10xy[/tex] are like terms, so we can add them together too.
[tex]-4xy + 2xy +10xy = 8xy[/tex]
There isn't anymore like terms, so now we need to put it in simplest form.
[tex]x^{2} +2y^{2} +8xy[/tex]
Hope this helps! I actually think 2y^2 is before x^2 in the answer, but unless you need it in simplest form it shouldn't matter. Review with your teacher before turning in if you can. :))

The slope of AB is different from the slope of BC
==================================================
Reason:
Points A,B,C are all on the same line. We consider them collinear points. This means that the slopes of AB, AC and BC are the same value.
If the slopes were different at all, then the points wouldn't be collinear. In this case, the slope is 2/3 because we move up 2 each time we move to the right 3 units.
And the slope of the line is constant

The curved surface area of a right circular cylinder of height 14 cm is 88 cm².
Answers
Answer:
The diameter of the base of the cylinder is 2 cm.
Step-by-step explanation:
GIVEN :
As per given question we have provided that :
➣ Height of cylinder = 14 cm➣ Curved surface area = 88 cm²[tex]\begin{gathered}\end{gathered}[/tex]
TO FIND :
in the provided question we need to find :
➠ Radius of cylinder ➠ Diameter of cylinder[tex]\begin{gathered}\end{gathered}[/tex]
USING FORMULAS :
[tex]\star{\underline{\boxed{\sf{\purple{Csa = 2 \pi rh}}}}}[/tex]
[tex]\star{\underline{\boxed{\sf{\purple{d = 2r}}}}}[/tex]
➛ Csa = Curved surface area ➛ π = 22/7➛ r = radius ➛ h = height ➛ d = diameter[tex]\begin{gathered}\end{gathered}[/tex]
SOLUTION :
Firstly, finding the radius of cylinder by substituting the values in the formula :
[tex] \begin{gathered} \qquad{\longrightarrow{\sf{Csa = 2 \pi rh}}} \\ \\ \qquad{\longrightarrow{\sf{88 = 2 \times \dfrac{22}{7} \times r \times 14}}} \\ \\ \qquad{\longrightarrow{\sf{88 =\dfrac{44}{7} \times r \times 14}}} \\ \\ \qquad{\longrightarrow{\sf{88 =\dfrac{44}{\cancel{7}}\times r \times \cancel{ 14}}}} \\ \\ \qquad{\longrightarrow{\sf{88 =44 \times r \times 2}}} \\ \\ \qquad{\longrightarrow{\sf{88 =88 \times r}}} \\ \\ \qquad{\longrightarrow{\sf{r = \frac{88}{88}}}} \\ \\ \qquad{\longrightarrow{\underline{\underline{\sf{\pink{r = 1 \: cm}}}}}} \end{gathered}[/tex]
Hence, the radius of cylinder is 1 cm.
———————————————————————
Now, finding the diameter of cylinder by substituting the values in the formula :
[tex]\begin{gathered} \qquad{\longrightarrow{\sf{d = 2r}}} \\ \\ \qquad{\longrightarrow{\sf{d = 2 \times 1}}} \\ \\ \qquad{\longrightarrow{\underline{\underline{\sf{\red{r = 2 \: cm}}}}}}\end{gathered}[/tex]
Hence, the diameter of the base of the cylinder is 2 cm.
[tex]\rule{300}{2.5}[/tex]
CSA of a cylinder = 88 cm²
height = 14 cm
diameter = ?
CSA of a cylinder = 88 cm²
2πrh = 88 cm²
____[tex]2 \times \frac{22}{7} \times r \times 14 = 88 cm²[/tex]
[tex]2 \times \frac{22}{1} \times r \times2 \: = 88 cm²[/tex]
[tex]2 \times 22 \times r \times 2 = 88 cm²[/tex]
[tex]88r = 88 cm²[/tex]
[tex]r = \frac{88}{88} [/tex]
[tex]r = 1 [/tex]
____Diameter = radius + radius
= 1 + 1
= 2
____Therefore, The Diameter of the base of the cylinder is 2.Levi is planning a road trip. He throws a dart on a map of the United States to decide where to go. There are 4 states that start with the letter A, 3 states that start with the letter C, and 8 states that start with the letter M. What is the probability that Levi throws a dart on a state that starts with an A or an M? (Hint: There are 50 total states.)
P(A∪M)=
1) 0.01
2) 0.24
3) 0.64
4) 0.42
Answers
Answer:
since there are 4 states that start with A and 8 that start with M, this means that out of the 50 states there are 12 states that he could throw a dart at and get either A or M, meaning that 12/50 is the fraction and 12/50 converted into a percentage or decimal is 0.24 meaning that 0.24 is the probability that he throws a dart and hits a state that starts with an A or M

Answer:
m∠4 = 140°
Step-by-step explanation:
m∠1 = m∠4 (parallel lines with same angle)
m∠2 = m∠3 (parallel lines with same angle)
if m∠2 = m∠3 are equal:
3x + 10 = 5x - 10
3x - 5x = -10 - 10
-2x = -20
x = 10°
m∠2 = m∠3 = 3x + 10 = 3(10) + 10 = 40°
m∠1 + m∠4 + 40° + 40° = 360°
2 m∠4 = 360° - 80°
2 m∠4 = 280°
m∠4 = 140°
Answer:
m∠4 = 140°
Step-by-step explanation:
Vertical Angle Theorem: vertical angles are always congruent.
Therefore, m∠1 = m∠4 and m∠2 = m∠3
As m∠2 = m∠3, then
⇒ 3x + 10 = 5x - 10
⇒ 20 = 2x
⇒ x = 10
So m∠2 = 3x + 10 = 3(10) + 10 = 40°
m∠2 and m∠4 form a linear pair
Therefore m∠2 + m∠4 = 180°
⇒ 40 + m∠4 = 180
⇒ m∠4 = 140°
Linear pair: a pair of adjacent angles formed when two lines intersect. The two angles of a linear pair always sum to 180°

Answers
Answer:
jim is 24 years old, Mark is 20 years old
Step-by-step explanation:
This prompt can be set up using this equation:
Let's represent Mark's age by variable m and Jim's age by variable J.
j + m = 44
m + 4 = j
m = j - 4
j + (j - 4) = 44
2j - 4 = 44
2j = 48
j = 24
So, jim is 24 years old, meaning mark must be 20 years old. 20 + 24 results in 44 years old together.
