Answer:
180 miles
Step-by-step explanation:
if you divide 72 by 4 you can see what 1/10 of the trip is, which is 18. 18 times 10 (since 18 is one tenth of it) equals 180. hope this helps!
(-3, -7). 1/7 what is the equation in point slope form
Answer:
y+7 = 1/7(x+3)
Step-by-step explanation:
Point slope form of a line is given by
y-y1 = m(x-x1)
where m is the slope and (x1,y1) is a point on the line
(y - -7) = 1/7(x - -3)
y+7 = 1/7(x+3)

Answer:
3[tex]\sqrt{3}[/tex] and [tex]\sqrt{7}[/tex]
Step-by-step explanation:
Simplifying surds is similar to collecting like terms in algebra.
If the surds have the same value then collect them by adding/ subtracting their coefficients.
(a)
[tex]\sqrt{3}[/tex] (7 - 2 + 1 - 3)
= [tex]\sqrt{3}[/tex] (3)
= 3[tex]\sqrt{3}[/tex]
(b)
[tex]\sqrt{7}[/tex] (5 + 4 - 8)
= [tex]\sqrt{7}[/tex] (1)
= [tex]\sqrt{7}[/tex]
Coach leonardo used 9 1/2 meters of string to mark a soccer field for a game. He also used 2 2/5 meters of string to mark a spot where coaches and players will be standing during the game. Which expression could be used to determine the amount of string in meters, coach lenore i used altogether
Answer:
10 19/10 meters
Step-by-step explanation:
Step one:
given data
let the amount of string used for the soccer field be x
and the amount used for coach spot be y
Also, let the total string used be represented as T
Step two:
Hence the expression for the total is
T= x+y
T= 9 1/2+ 2 2/5
T= 9.5+ 2.4
T= 11.9
or
T= 119/10 meters
or
T= 10 19/10 meters
Help pls I will mark as brainlest if correct
Answer:
The slope is [tex] \frac{3}{8} [/tex].
Step-by-step explanation:
Remember: [tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
☆Just plug in.
[tex]m = \frac{ - 7 - ( - 10)}{0 - ( - 8)} = \frac{3}{8} [/tex]

Given: sin(A) = 4/5, pi/2 < A < pi and sin(B) = -2root5/5, pi < B < 3pi/2 What is the value of cos(A – B)?
Answer:
-√5/5
Step-by-step explanation:
Given the following
sin(A) = 4/5
sinB - -2√5/5
SinA = 4/5 = opp/hyp
We can get cosA
opposite = 4
hypotenuse = 5
Adj = √5²-4² (pythagoras theorem)
Adj = √25-16
Adj = √9
Adj = 3
Cos A = Adj/hyp
Cos A = 3/5
Also
Sin B = -2√5/5 = opp/hyp
opposite = -2√5
hypotenuse = 5
Adj = √5²-(2√5)² (pythagoras theorem)
Adj = √25-20
Adj = √5
Cos B = Adj/hyp
Cos B = √5/5
Evaluate cos (A-B)
cos (A-B) = cosAcosB + sinAsinB
cos (A-B) = 3/5(√5/5)+4/5(-2√5/5)
cos (A-B) = 3√5/25 - 8√5/25
cos (A-B) = -5√5/25
cos (A-B) = -√5/5
Hence the value of cos (A-B) is -√5/5

Question 4 Given: f(x) = -3x – 3 and g(x) = x2 + 5 Find (f - g) ().
Answer:
We get [tex]\mathbf{(f-g)(x)= -x^2-3x-8}[/tex]
Step-by-step explanation:
We are given:
[tex]f(x) = -3x - 3\\ g(x) = x^2 + 5[/tex]
We need to find (f-g)(x) (assuming there is x in the bracket, i.e. (f - g) () should be (f-g)(x))
We would simply subtract f(x) and g(x)
[tex](f-g)(x)\\= -3x-3-(x^2+5)\\Multiply\:minus\:sign\:with\:terms\:inside\:the\:bracket\\=-3x-3-x^2-5\\Combining\:like\:terms:\\=-x^2-3x-3-5\\=-x^2-3x-8[/tex]
So, We get [tex]\mathbf{(f-g)(x)= -x^2-3x-8}[/tex]

y = [-7, 0] or - 7 ≤ y ≤ 0Step-by-step explanation:
The range is the set of y- values of a function
As per graph y-value changes from -7 to 0 both inclusive, so the range is:
y = [-7, 0]or
- 7 ≤ y ≤ 0any answers? im bit stuck on this
Step-by-step explanation:
The vertical angles are congruent. The right angles are congruent. There are 2 angles of a triangle congruent to 2 angles of anther triangle. By AA Similarity the triangles are similar.
Statement A. (vertical angles are congruent)
Statement D. (right angles are congruent)
Triangle AEC is similar to triangle BDC.
Statement E is true but does not help.
Correct statement of proportional side lengths:
BD/AE = CD/CE
x/150 = 200/50
x/150 = 4
x = 600
P.S. I think there is a mistake in the problem. I don't think that statement E is correct. It is a true statement, but it is useless. Statement F is false.

I need help ASAP, The question is to Evaluate x^2-2y when x=4 and y=1, I don't understand at all helppp.
Answer:
14
Step-by-step explanation:
4^2 - 2(1)
16-2= 14
I hope this helped <3
Answer:
14
Step-by-step explanation:
plug in the values for x and y
if x = 4 then we have 4²- 2y
then it also says y = 1 so we now have 4²- 2(1)
4 squared is 16 and 2 times 1 is 2
16 - 2= 14
LOOK AT PIC ATTACHED AND HELP NOW
Answer:
a. Line BC and Line GH
b. Line AC and line AJ
c. No, because if they were perpendicular, they would intersect at a 90 degree angle.
Step-by-step explanation:
a. Whenever two lines share identical little triangle marks - such as line BC and line GH in this case - it indicates that those lines are parallel.
b. The little red square at the intersection of line AC and line AJ indicates a 90 degree angle. Whenever two lines intersect at a 90 degree angle, it means they are perpendicular. So, Line AC and line AJ would be perpendicular.
c. The upside down T symbol means "perpendicular," so the question is asking if line BC and line AJ are perpendicular. However, they cannot be since there is no indication on the diagram that they do - no symbols of 90 degree angles - that we can use to prove that they are perpendicular.

If you are trying to find the perimeter, it should be 40.
the difference of 2x and 15 is less than or equal to the sum of 4x and 17
Step-by-step explanation:
the difference of 2x and 15 is less than or equal to the
sum of 4x and 17
i.e.,
2x - 15 < 4x + 17
if you want to find ahead then
2x - 15 = 4x + 17
2x - 4x = 17 + 15
- 2x = 32
x = - 32/2
x = - 2
