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
PLEASE ANSWER PLZ PLZ
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]
9. The quotient of n and -4 is 5. What is the
value of n?
Answer:
n=-20
Step-by-step explanation:
Answer:
n = -20
Step-by-step explanation:

Will mark brainliest
Answer:
D)
Step-by-step explanation:
x² + 3x + (3/2)² = 6 - 8 + (3/2)²
(x + 3/2)² = -2 + 9/4
(x + 3/2)² = -8/4 + 9/4
(x + 3/2)² = 1/4
Answer:
D is the answer
Step-by-step explanation:
x² + 3x + (3/2)² = 6 - 8 + (3/2)²
(x + 3/2)² = -2 + 9/4
(x + 3/2)² = -8/4 + 9/4
(x + 3/2)² = 1/4

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).

Answer:
[tex]x=5\sqrt{3}[/tex]
Step-by-step explanation:
Evaluate the Pythagorean Theorem for the triangle.
a² + b² = c²
5² + x² = 10²
25 + x² = 100
Subtract 25 from both sides.
x² = 75
Square root.
x = sqrt(75)
Expand the radical.
x = 5*sqrt(3)

blue hats in her hat collection is 10:9. Which ratio is
equivalent to 10:9?
Answer:
20:18 30:27 40:36 etc..
Step-by-step explanation:
To find equivalent ratios you multiply both 10 and 9 by the same number to find equivalent ratios.
Which could be the first step in solving this system of equations by substitution?
y = 7x
y - x = 15
Answer:
The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)
solve and get
(2.5,17.5)
or x= 2.5 y=17.5
Step-by-step explanation:
The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x
7x-x=15
6x=15
x=2.5
Then we can solve for y
y=7(2.5)
y=17.5
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".

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

Step-by-step explanation:
find the radius of the circle with center (2,2) that passes through (-9,-4)
Answer:
√157 units or about 12.53 units
Step-by-step explanation:
Equation of circle: (x-h)²+(y-k)²=r²
Center: (h,k) -> (2,2)
Equation so far: (x-2)²+(y-k)²=r²
Plug in (-9,-4) to find r: (-9-2)²+(-4-2)²=r² -> 121+36=r² -> 157=r² -> √157=r
Therefore, the radius of the circle is √157 units or about 12.53 units

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.
Which number line shows the solutions to n> 0?
Answer:
Choice A
