Answer:
The system has no real solutions.
Step-by-step explanation:
hello :
the system is : y=-3x² - 4x +7.....(*)
3x + 2y = 18.....(**)
use (*) put tue value for y in (**) : 3x+2(-3x² - 4x +7) = 18
3x+-6x² -8x +14 = 18
-6x²-5x-4 =0
6x²+5x+4 =0
use this equation calculate : delta = 5²-4(6)(4) = -71
delta negatif :The system has no real solutions.
If one adult works 4 weeks per month at
40 hours per week, what is the minimum hourly
wage, to the nearest cent, that person must
earn in order to meet the family's budget
needs?
Answer:
15.21
Step-by-step explanation:
All of the bills total to $2432.50. The person works 160 hours in a month. $2432.50 ÷ 160 = $15.20, BUT:
$15.20 × 160 = $2432, which is 50 cents short of what they need, so one extra cent in their wage will give them the amount they need.
$15.21 × 160 = $2433.60
19mn + 14t + 8t(2) - 3mn +(-2t) + 5t(2) =

Answer:
x = 1.5
Step-by-step explanation:
Here, we want to solve for the value of x
In other to solve this, we will be using an important theorem
We have this as;
lh^2 = lj * lk
1^2 = 0.5 * (0.5 + x)
1 = 0.25 + 0.5x
1-0.25 = 0.5x
0.75 = 0.5x
x = 0.75/0.5
x = 1.5

Please help me out with this no links and no stealing points
Answer:
TQ = 24
Step-by-step explanation:
Δ RST and Δ RPQ are similar, thus ratios of corresponding sides are equal, that is
[tex]\frac{RS}{RP}[/tex] = [tex]\frac{RT}{RQ}[/tex] , substitute values
[tex]\frac{15}{35}[/tex] = [tex]\frac{18}{RQ}[/tex] ( cross- multiply )
15 RQ = 630 ( divide both sides by 15 )
RQ = 42
Then
TQ = RQ - RT = 42 - 18 = 24

Answer:
80%of 25 is 20
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
To solve we must first find what 80% is in decimal form.
to do this we can move the decimal place to the left 2 spots
80% ---> 0.80
We can now multiply this decimal by 25
25 × 0.80 = 20

Carol is comparing two rectangular tiles for a flooring project. The blue tile is 8 centimeters long and 6 centimeters wide. The yellow tile is is 70 milimeters long and 68 milimeters wide. Which tile covers the greater area? How much greater is the area. Use the sentence frame to answer.=: The_____ Tile covers more area by ________.
Answer:
The Blue Tile covers more area by 40 mm^2
Step-by-step explanation:
convert centimeter to millimeters
1cm = 10 mm
(6 x 10) by (8 x 10)
Area of a rectangle = length x breadth
60 x 80 = 4800
70 x 68 = 4760
difference = 4800 - 4760 = 40

Which graph represents a positive correlation?
Answer:Your answer is C
Step-by-step explanation:
Enter the equation of the circle with the given center and radius.
Center: (0, 5); radius: 5
The equation of the circle is
Answer:
[tex](x-0)^{2} + (y-5)^{2} = 25[/tex]
Step-by-step explanation:
The "template" equation of a circle is:
[tex](x-h)^{2} + (y-k)^{2} = r^{2}[/tex]
All you're doing after that, is filling in the blanks:
h = 0
k = 5
r = 5
Answer:
Correct answer:
(x−0)² + ( y−5)²=5²
Explanation:
The equation of a circle is (x−h)²+(y−k)²=r²
The center is (0,5) or, written another way (h,k). Substituting 0 for h and 5 for k, our formula becomes (x−0)²+(y−5)²=5²
Finally, the formula of the circle is (x−0)²+(y−5)²=25

Armando used algebra tiles to represent the product 3 x (2 x minus 1). An algebra tile configuration. 3 tiles are in the Factor 1 spot and are labeled + x. 3 tiles are in the Factor 2 spot: 2 are labeled + x and 1 is labeled negative. 15 tiles are in the Product spot: 2 are labeled + x squared, 4 are labeled + x, 1 is labeled negative x, and 4 are labeled negative. Which is true regarding Armando’s use of algebra tiles? He used the algebra tiles correctly. He did not represent the two original factors correctly. The signs on some of the products are incorrect. Some of the products do not show the correct powers of x.
Answer:
Some of the products do not show the correct powers of x.
Step-by-step explanation:
From the picture,
3x(2x - 1) = 6x² - 3x
The correct display on the tile should look like this :

O 0.25 inches = 1 foot
O 26 feet x 19 feet
O 12 inches in 1 foot
Room holds 1427 rubber ducks
Pls help me :3
Answer:
12 inches in 1 foot
Step-by-step explanation:
In this problem, we need to find an example that is a scale.
There must be a relation between two units.
There are many types of units of lengths. These can be metre, cm, mm, foot, inches.
The relation between inch and foot is given by :
1 foot = 12 inch
So, we can say there are 12 inches in 1 foot.
Hence, the correct option is (c).
