1.78 rounded to the nearest tenth is 1.8
Solve |4x +2|= 6
a.1 or -2
b.-1 or 2
c.1
s.2
Answer:
A
Step-by-step explanation:
When taking out the absolute value, it's 4x+2=6 and 4x+2=-6. At this point just solve for x and your answer(s) should be 1/-2
Answer:
x =1 x=-2
Step-by-step explanation:
|4x +2|= 6
There are two solutions a positive and a negative
4x+2 = 6 and 4x+2 = -6
Subtract 2 from each side
4x+2-2 = 6-2 4x+2-2 = -6-2
4x = 4 4x = -8
Divide by 4
4x/4 = 4/4 4x/4 =-8/4
x =1 x = -2

A figure in the first quadrant is rotated 180° counterclockwise about the origin. In which quadrant will the rotated figure appear?
Answer:
It will be in the 3rd quadrant.
Step-by-step explanation:
Hope that helps!
Answer:
The rotated figure appears in the 3rd quadrant
Step-by-step explanation:
To visualize a problem can sometimes be challenging.
It usually helps to make a sketch of the situation, to get a "feel" it of what is happening.
Supose a little cube is placed on the x axis, in quadrant 1, starting at ( 1. 0), and with size 1 unit.
Corner coordinates are therefore:
A =( 1, 0)
B =( 2, 0)
C =( 2, 1)
D =( 1, 1)
Rotate for 180 degrees about the origen (EXTRA: a ounterclockwise rotation over 180° is exactly the same as a clockwise rotation over 180°).
The new coordinates are:
A' =(-1, 0)
B' =(-2, 0)
C' =(-2 -1)
D' =(-1, -1)
These are all in third quadrant.
Therefore, the rotated figure appears in the 3rd quadrant
What is the solution to the system of linear equations?
{2x + 4y = 20
{3x + 2y = 26
Enter your answer in the boxes.
Answer:
x = 8, y = 1.
Step-by-step explanation:
2x + 4y = 20
3x + 2y = 26 Multiply this equation by -2:
-6x - 4y = -52 Add this to the first equation:
-4x = -32
x = -32/-4
x = 8.
Plug x = 8 into the first equation:
2(8) + 4y = 20
4y = 20 - 16 = 4
y = 1.

What is the vertex of the parabola given by y = x2 − 10x + 17? A. (5, -8) B. (-5, 8) C. (5, 8) D. (-5, -8)
Answer:
A
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 ), then
The x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
y = x² - 10x + 17 ← is in standard form
with a = 1 and b = - 10, thus
[tex]x_{vertex}[/tex] = - [tex]\frac{-10}{2}[/tex] = 5
Substitute x = 5 into the equation for corresponding value of y
y = 5² - 10(5) + 17 = 25 - 50 + 17 = - 8
vertex = (5, - 8 ) → A

ram is half his fathers age now. ten years ago he was one third his fathers age then what are their present ages
x - Ram's age now
Ram is half his father's age now, so his father's age is two times Ram's age:
2x - Ram's father age now
x - 10 - Ram's age ten years ago
2x - 10 - Ram's father age ten years ago
ten years ago he was one third his father's age so his father's age was three times Ram's age:
2x - 10 = 3•(x - 10)
2x - 10 = 3x - 30
-10 + 30 = 3x - 2x
20 = x
2x = 2•20 = 40
Answer:
Ram is 20 years old now, Ram's father is 40 years old now.

Can someone please help me with this I need help finding x and y using special right triangles and if you could please explain how
Answer:
y=46.445
x=24.04
Step-by-step explanation:
rule for first triangle which is right isosceles triangle with angles 30-60-90
sin 30 = opp/hypt.
0.5= opp/34
opp=17 which is the height
the part of y in the first triangle = a^2+b^2=c^2
a^2= 17^2 , b^2=y , c^2 =34
y ( first triangle )= √867=29.445
second triangle is right angle triangle 45-90-45
x= 24.04
sin 45= opp/hypt.
1/√2 =17/x
x= 17*√2 = 24.04
solving for other part of y in the right triangle
h= y = 17
the whole base y= 29.445+17 = 46.445

Esteban's credit card issuing bank charges him an APR of 16% on new purchases, and 24% on
cash advances. What would the bank charge Esteban monthly in finance charges for a $700 cash
advance?
Answer: $14
Step-by-step explanation:
Hi, to answer this question we have to multiply the amount of the cash advance (700) by the APR for cash advances in decimal form (divided by 100):
700 x (24/100) = $168 (a year)
To obtain the monthly charges, we have to divide the result by the number of months in a year (12):
168 /12 = $14
Feel free to ask for more if needed or if you did not understand something.

Answer:
144 cm²
Step-by-step explanation:
for the triangle sides: 3 x 4 = 12 ((3 x 4/2)x 2)
for the front: 5 x 11 = 55
for the back: 3 x 11 = 33
for the base: 4 x 11 = 44
12 + 55 + 33 + 44 = 144
Answer:
144 units²
Step-by-step explanation:
We can see this shape is made of 2 shapes that we are familiar with 3 rectangle's and 2 triangles. In order to work out the surface of the prism we need to know how to work out the area of a rectangle and a triangle.
→ Area of triangle = 0.5 × Base × Height
→ Area of rectangle = Length × Width
First let's work out the area of the triangle and then double it to find the added area of the 2 triangle's
Area of triangle = 0.5 × Base × Height
→ Substitute in the values
Area of triangle = 0.5 × 4 × 3
→ Simplify
Area of triangle = 6
Then double this value to find the combined value of the 2 triangle's
6 × 2 = 12
Now the area of the large rectangle
Area of rectangle = Length × Width
→ Substitute in the values
Area of rectangle = 11 × 5
→ Simplify
Area of rectangle = 55
Now the area of the medium rectangle
Area of rectangle = Length × Width
→ Substitute in the values
Area of rectangle = 11 × 4
→ Simplify
Area of rectangle = 44
Now the area of the small rectangle
Area of rectangle = Length × Width
→ Substitute in the values
Area of rectangle = 11 × 3
→ Simplify
Area of rectangle = 33
Now we add all the area's together,
33 + 44 + 55 + 12 = 144

Wyatt has 222 one dollar bills, 222 five dollar bills, and 222 ten dollar bills. How much money does he have in all?
Answer:
$3,552.00
Step-by-step explanation:
First, you need to multiply 222 by 5. You will get 1110. Next, you need to multiply 222 by 10. You will get 2220. Now you take the 222 1 dollar bills and add it to the 1110 dollars, then add the 2220 to that. You will get the final number of 3552.
Here's the equation in what I call "Long Boi Form:"
222x5=1110 222x10=2220 1110+2220+222=3552
