plz help me hurry
Answer:
x=-1
Step-by-step explanation:
-2x - 5 = -3
add 5 to both sides
-2x = 2
divide both sides by -2
x = -1
Answer:
x = -1
Step-by-step explanation:
-2x - 5 = -3
Same to both sides:
-2x = -3 + 5
Simplify:
-2x = 2
Divide by -2 on each side to isolate x:
x = -1

When is the graph of f (x) = 2x2 – 5x – 3 negative?
9514 1404 393
Answer:
-1/2 < x < 3
Step-by-step explanation:
First you need to find the x-intercepts. Since the leading coefficient is positive, you know the graph is decreasing through the left x-intercept, so will be negative between the x-intercept values.
f(x) = 2x^2 -5x -3
f(x) = 2x^2 -6x +x -3
f(x) = 2x(x -3) +1(x -3)
f(x) = (2x +1)(x -3)
The x-intercepts are the values of x that make these factors zero:
2x +1 = 0 ⇒ x = -1/2
x -3 = 0 ⇒ x = 3
The graph of f(x) is negative on the interval ...
-1/2 < x < 3
Susan Carver will purchase a home for $190000. She will use a down payment of 18% and finance the remaining portion at 4.2%, compounded monthly for 30 years
Answer:
$548053.69
Step-by-step explanation:
Cost of home = $190000
Down payment = 18%
Loan amount = (1 - 0.18) * 190000 = $155800
Rate, r = 4.2% = 0.042 ; compounded monthly for 30 years
Using the relation :
A = P(1 + r/n)^nt
n = number of compounding times per period = 12
A = 155800(1 + 0.042/12)^(12 * 30)
A = 155800(1.0035)^360
A = 155800 * 3.5176745
A = 548053.69
Final loan amount = $548053.69

how many odd integers are between -20 and 10?
9514 1404 393
Answer:
15
Step-by-step explanation:
The given range of numbers is -20 to 10, so is 10-(-20)+1 = 31 numbers. Since the end points of the range are both even, there is one more even number than there are odd numbers in the range. The number of odd numbers is ...
(31 -1)/2 = 15
There are 15 odd numbers between -20 and 10.
In the figure above, PQRS is a circle. If PQT and SRT
are straight lines, find the value of x.
Given:
PQRS is a circle, PQT and SRT are straight lines.
To find:
The value of x.
Solution:
Since PQRS is a circle, PQT and SRT are straight lines, therefore, PQRS isa cyclic quadrilateral.
We know that, sum of opposite angles of a cyclic quadrilateral is 180 degrees.
[tex]m\angle SPQ+m\angle QRS=180^\circ[/tex]
[tex]81^\circ+m\angle QRS=180^\circ[/tex]
[tex]m\angle QRS=180^\circ-81^\circ[/tex]
[tex]m\angle QRS=99^\circ[/tex]
Now, SRT is a straight line.
[tex]m\angle QRT+m\angle QRS=180^\circ[/tex] (Linear pair)
[tex]m\angle QRT+99^\circ=180^\circ[/tex]
[tex]m\angle QRT=180^\circ-99^\circ[/tex]
[tex]m\angle QRT=81^\circ[/tex] ...(i)
According to the Exterior angle theorem, in a triangle the measure of an exterior angle is equal the sum of the opposite interior angles.
Using exterior angle theorem in triangle QRT, we get
[tex]m\angle PQR=m\angle QRT+m\angle QTR[/tex]
[tex]x=81^\circ+22^\circ[/tex]
[tex]x=103^\circ[/tex]
Therefore, the value of x is 103 degrees.

Sara was cliff jumping. She was on a cliff 25 feet above sea level. She jumped into the sea and descended a total of 37 feet. How many feet below sea level did she travel? Justify your reasoning.
Answer:
12 feets below sea level
Step-by-step explanation:
Initial height = 25 feets above sea levwl
Total descent = 37 feets
Distance traveled below sea level = 37 feets - 25 feets = 12 feets
Hence, Sarah traveled 12 feets below sea level
Find the value of x.
Answer:
x=7
Step-by-step explanation:
Since the two lines, the transversal intersects are parallel we know that the angles are same-side interior. This means they are supplementary or add up to 180. Therefore, to solve add the two expressions and set them equal to 180, then solve with properties of equality.
14x+7+10x+5=180
First, add like terms
24x+12=180
Then, subtract 12 from both sides
24x=168
Next, divide both sides by 24
x=7

PLEASE HELP,, A home decorator is adding new flooring to a living room using the blueprint shown.

What are the actual length and width of the living room? Show your work.
A.
7ft, 6ft
B.
14 ft, 10ft
C.
10ft, 8ft
D.
20ft, 16ft
Answer: 20ft, 16ft
Step-by-step explanation:
Because 0.5in=2ft, you would divide the length (5in) and the width (4) both by 0.5. Which give you 10 for the length and 8 for the width. Then you multiply both of those products by 2 and that gives you your answer. 20ft and 16ft. Hope this helps. :)

Please Help!!!!!! Use what you've learned today about the sum of the interior angles of triangles and quadrilaterals to determine the measure of ALL unknown angles in the figure below.
Answer:
m = 116
x = 24
y = 76
z = 40
Step-by-step explanation:
For startes the interior angles of triangles always add up to 180 degrees.
That means....
73 + 83 + x = 180
z + m + x = 180
z + y + 64 = 180
Another important fact is that two angles that are intersected by a line in the case 64 and m always add up to 180 degrees.
So m + 64 = 180
Let's start with 73 + 83 + x = 180
If you add 73 and 83 you get 156
x + 156 = 180 then subtract 156 from both sides and
x = 24
Then use m + 64 = 180 subtract 64 from both sides and
m = 116
z + m + x = 180 become
z + 116 + 24 = 180
Add 116 and 24 and you get 140
z + 140 = 180 subtract 140 from both sides and
z = 40
Check to make sure m + x + z = 180
24 + 40 + 116 = 180
z + y + 64 = 180 becomes
y + 40 + 64 = 180
40 + 64 = 104 so
y + 104 = 180 subtract 104 from both sides and
y = 76
Congratulations you have found all of the angles!
1. Add the same number to both the numerator and the denominator of
the fraction 7/17, to change it to 3/5.
Answer:
8
Step-by-step explanation:
Let x be the number added to both numerator and denominator.
Initial fraction=7/17
After adding x to both the numerator and the denominator
Then ,we get fraction=3/5
We have to find the value of x.
According to question
[tex]\frac{7+x}{17+x}=\frac{3}{5}[/tex]
[tex]5(7+x)=3(17+x)[/tex]
[tex]35+5x=51+3x[/tex]
[tex]5x-3x=51-35[/tex]
[tex]2x=16[/tex]
[tex]x=\frac{16}{2}=8[/tex]
