A triangle has an area of 49.5cm2 If the base of the triangle is 9cm. What is the height of the triangle A = 1/2BH
Answer: 11
Step-by-step explanation:
49.5/9 = 5.5
5.5 x 2 =11
11x9=99
99/2=49.5
Write an equation in slope-intercept form for the line with slope 7 and y-intersept -7
Answer:
y = 7x - 7
Step-by-step explanation:
1st we can look at the meaning of a slope intercept equation
y = mx = b
m = the slope
b = the y-intercept
now when looking at your equation you can plug in your numbers.
y = 7x - 7 is your final answer
High Hopes ^^

Evaluate the piecewise defined function at the indicated values.
{x² + 4x if x <equal/greater to -1
f(x) = { x if - 1<x< equal/greater to 1
{-1 x > 1
f(-2)=
f(-3/2)=
f(-1) =
f(0) = 0
f(25) =
Given:
Consider the piecewise function is
[tex]f(x)=\left \{\begin{matrix}x^2+4x,\text{ if } x\leq -1\\ x, \text{ if }-1<x\leq 1\\-1,\text{ if }x>1\end{Matrix}\right.[/tex]
To find:
The value of the function at indicated values.
Solution:
We know that, [tex]-2,-\dfrac{3}{2},-1[/tex] are less than or equal to -1. So, for these values the function is [tex]f(x)=x^2+4x[/tex].
For x=-2,
[tex]f(-2)=(-2)^2+4(-2)[/tex]
[tex]f(-2)=4-8[/tex]
[tex]f(-2)=-4[/tex]
Similarly,
For [tex]x=-\dfrac{3}{2}[/tex].
[tex]f(-\dfrac{3}{2})=(-\dfrac{3}{2})^2+4(-\dfrac{3}{2})=-\dfrac{15}{4}[/tex]
For [tex]x=-1[/tex].
[tex]f(-1)=(-1)^2+4(-1)=-3[/tex]
We know that, 0 is lies between -1 and 1. So, for this values the function is [tex]f(x)=x[/tex].
For x=0,
[tex]f(0)=0[/tex]
We know that, 25 is greater than 1. So, for this values the function is [tex]f(x)=-1[/tex].
For x=25,
[tex]f(25)=-1[/tex]
Therefore, the required values are, [tex]f(-2)=-4, f(-\dfrac{3}{2})=-\dfrac{15}{4},f(-1)=-3,f(0)=0,f(25)=-1[/tex].

Answer:
Domain(x): -2,2,3
Range(y): -1,4,5,6
(I put them in order numerically)
Step-by-step explanation:
The Domain is all the x values of the points given. It's always the first number of a point.
The range is the y values, it's always the second number given in a ordered pair!

2x+y=9 let x=3 what is y
Answer:
3
Step-by-step explanation:
Step 1:
2x + y = 9 Equation
Step 2:
2 ( 3 ) + y = 9 Input x
Step 3:
6 + y = 9 Multiply
Step 4:
y = 9 - 6 Subtract 6 on both sides
Answer:
y = 3

What is x if f(x)=-2
f(x) = -2
f(x) is the same thing as x
f(x) is the same thing as -2
Now think about it. If f(x) and -2 are the same thing, what is x?

Use f(x) = 1/2x and f -1(x) = 2x to solve the problems.
f(2) =
f−1(1) =
f−1(f(2)) =
[tex]f(2) = \frac{1}{2} \times 2 = 1\\f^{-1}(1) = 2 \times 1 = 2\\f^{-1}(f(2)) = f^{-1}(1) = 2[/tex]
Note: [tex]f^{-1}(f(x)) = x[/tex] because f -1 and f cancel each other out.
Answer:
f(2) =
⇒ 1
f−1(1) =
⇒ 2
f−1(f(2)) =
⇒ 2
f−1(−2) =
⇒ -4
f(−4) =
⇒ -2
f(f−1(−2)) =
⇒ -2

Since we know that the 2 lines are parellel, we know that the angles will add up to 180
sooo
180-119=61 (The angle in the traingle)
We know that the angles of a trinalge add up to 180
61+18+e=180
e=101 degrees
Kendall measured the temperature outside to be 68°F. She needs to convert the temperature to degrees celsius.
C=5/9(F-32)
[]68°F is 20°C
[]68°F is 5.7°C
Answer:
68°F is 20°C
Step-by-step explanation:
C = (5/9)(F - 32)
C = (5/9)(68 - 32)
C = (5/9)(36)
C = 5 * 4
C = 20
Answer: 68°F is 20°C

Pythagorean Theorem!!! someone pls help tyyy
Answer:
43.7
Step-by-step explanation:
7[tex]7^{2} +7^{2} =\sqrt{98} \\\sqrt{98}=9.899494937\\ That is the measurement for the dotted line. If we round it like they did in the example it would be 9.90. That is the measurement for all the sides of the square. \\We need the measurement for only 3 sides of the square and the two outer sides of the triangle (7ft)\\7ft + 7ft + 9.90 + 9.90 + 9.90 = 43.7\\\\Joshua added the 7's and they square rooted them for the Hypotenuse.\\Then the perimeter of all sides did not need any square roots.[/tex]

8n + 8 =-56 its a two step equating help please
Answer:
n = -8
Step-by-step explanation:
Original Equation:
8n + 8 = -56
Subtract 8 from boths sides.
8n = -64
Divide both sides by 8
n = -8
Hope this helped :)
Please consider Brainliest :)
Step-by-step explanation:
its -8
8n + 8 = 56
8n + 8 - 8 = 56 - 8
8=−64
8n/ 8 -= -64
8n / 8 = -64 / 8
simplified = n = - 8
n equals -8
