Answer:
Your answer is -5/2.
Step-by-step explanation:
Use the slope equation. (Refresh if you cant see below.)
[tex]\frac{y_2-y_1}{x_2-x_1}\\\text{Substitute two points into the equation. We can use the first two, (3, 5), and (5, 0).}\\\frac{0-5}{5-3}\\\text{Subtract.}\\-\frac{5}{2}[/tex]
A rectangular flower bed has a width of (2x+5) and a length of (x+10). Find the area of the flower bed when the length is 25 ft
Answer:
875 ft
Step-by-step explanation:
Length is 25 feet so we can solve x with the equation x+10=25 so x=15
We can plug in 15 to find out the width. 2(15)+5=w, so w(width) is 35.
Area is length x width, length=25 and width=35 so 35 x 25= 875
875 ft

The following tables show the values of linear , quadratic, and exponential functions for various values of . Indicate which function type corresponds to each table. Justify your choice. с у Y X у 6 1 1 71 56 6 1 14 9 2 9 2 28 N N 28 12 3 3 14 14 3 15 4 4 4 7 56 21 D B
Answer:
Step-by-step explanation:
Consecutive differences in Table A are constant (9−6=12−9=15−12=3), indicating a linear function. Consecutive quotients in Table B are constant (147=2814=5628=2) indicating an exponential function. Similarly the constant quotient for Table D is 1/2. Neither consecutive differences nor quotients are constant in Table C, and its ordered pairs are related by the equation y=x2+5. So, Table A should be labeled "linear", Table B and D, "exponential", and Table C, "quadratic".
Anna is solving this equation:
7 - 3(2x - 5) = -(3x + 7)
Anna uses the distributive property for her first step.
Which equation shows the correct result of Anna using the distributive property?
O A. 7-6x - 5 = -3x + 7
B. 7 - 6x + 5 = -3x - 7
C. 7 - 6x - 15 = -3x + 7
D. 7 - 6x + 15 = -3x - 7
Answer:
7-6x+15=-3x-7

Nico practiced drums 1.5 fewer hours than he practiced piano. If Nico practiced the piano for 4 hours, how many hours did Nico practice the drums
Answer:
2.5 hours
Step-by-step explanation:
4 - 1.5 = 2.5
You must subtract 1.5 from the amount of hours he plays piano, which is 4. This is because he spends 1.5 hours less playing drums than he does playing piano.

Answer:
y= -2x+ 5
Step-by-step explanation:
parallel with y= -2x+ 1 means the lines have the same slope m= -2
from point (-1, 7) we go with a slope of -2 until we find the y-intercept (0, 5)
y= mx+b is the general formula
y= -2x+ 5
Which of the following shows the quadratic formula correctly used to solve the

Find the volume of an construction cone if it has a radius of 4 inches and a height of 16 inches.
Answer:
≈ 268 or 85.3π
Step-by-step explanation:
V = 1/3πr²h
V = 1/3 x 3.14 x 4² x 16
V ≈ 267.9467 or 268
also can be considered 85.3π

Helppppppoppp please 10 points !!!
Answer:
2x+27+x+27=180
3x+54=180
3x=180-54
x=126/3
x=42
angle B=x+27
=42+27
=69 degree
Step-by-step explanation:
Answer:
B=69
Step-by-step explanation:
Supplementary angles have a sum of 180. Set up your formula as
180=(2x+27)+(x+27)
180=2x+27+x+27
180-27-27=3x
126=3x
126/3=x
42=x
Now substitute 42 in place of x for Angle B
Angle B = x+27
B = 42+27
B=69
Check your work by doing the same for Angle A
Angle A = (2x+27)
A=2*42+27
A=84+27
A=111
Now add both together and if you did it right, your answer is 180
69+111 = 180

What is the equation of a circle with a radius of 6 and a center at ( -2 , 3 )?
Answer:
Solution given:
centre(h,k)=(-2,3)
radius(r)=6 units
we have
equation of a circle is:
(x-h)²+(y-k)²=r²
(x+2)²+(y-3)²=6²
(x+2)²+(y-3)²=36 is required equation of a circle.
2. What is a line of symmetry?
(1 Point)
Answer:
Step-by-step explanation:
I believe you're refering to an "axis of symmetry." This is most often seen in quadratic equations. If the parabolic graph opens up or down, the axis of symmetry is the vertical line passing through the vertex, and the graph is symmetrical about this axis. The same applies to a parabolic graph that opens left or right.
If y = ax^2 + bx + c, the equation of the axis of symmetry is x = -b / (2a).
