Answer:
True
Step-by-step explanation:
(-1,4) = (x,y)
This means if "x = -1, then y should be 4"
y = 3x + 7
y = 3(-1) + 7
y = -3 + 7
y = 4
It is saying if x is -1, y is 4. This statement of "Is (-1,4) a solution to the graph of "y = 3x + 7?" Is true. You can also graph this and find the point (-1,4) and it would be on the line.
:D Hope it Helps (I dunno why I put it on this answer box now)
Answer:
Yes.
Step-by-step explanation:
Note that the point:
(x , y) = (-1 , 4)
x = -1
y = 4
Plug in the corresponding numbers for the corresponding variables in the given equation:
y = 3x + 7
(4) = 3(-1) + 7
Remember to follow PEMDAS. PEMDAS is the order of operation, and stands for:
Parenthesis, Exponent (& Roots), Multiplication, Division, Addition, Subtraction.
First, multiply 3 with -1:
4 = (3 * -1) + 7
4 = -3 + 7
Next, simplify by adding -3 with 7:
4 = (-3 + 7)
4 = 4
Yes. (-1 , 4) is a solution for y = 3x + 7, as the two sides of the equation equal.

An object containing the point (-6, 10) was moved to the location (12, -2). Which choice best described the translation?
A right 12, down 12
Bright 6, down 10
right 18, down 12
Dright 18, up 12
Answer:
C right 18, down 12
Step-by-step explanation:
Well firstly,
you should focus on the x in both the previous and after location of the object.if you minus 12 from the after point (12,-2) by -6 from the previous point (-6,10) for the object, you'll get 18 which is positive, which means that the object will moves to the right side of the graph →
12 - (-6)
= 18
Next,
you should now focus on the y in both the previous and after location of the object.you should minus -2 by 10 and you'll get -12, which means that the object will moves to the down side of the graph ↓
-2 - 10
= -12
So, the object will move 18 boxes to the right and 12 boxes down to achieve the after, final or last location as stated in the question (12,-2)

A park charges $8 per hour to rent a bike
Choose the equation that models the situation, where c represents the total cost and
h represents the number of hours of bike rental.
please solve and explain !!!
Answer:
107
Step-by-step explanation:
Angle 1
When a line is passes through a straight line, the two angles must equal 180 degrees. Since you know the one angle is 81, then angle 1 is 180 - 81 or
99 degrees.
Angle 2
You can determine the angle that is opposite of the 91 angle. These two angles must add up to 180. So the angle to the right of 91 must be 89.
89 + 91 = 180
You were told lines c and d are parallel. Based on that, the angle you just calculated must be equal to angle 2 or 89 degrees.
Angle 3
Again, you know that lines c and d are parallel. When a line crosses over two parallel lines, the outer opposite angles would be equal to each other.
So angle 3 is equal to the angle marked as 81 degrees.
Angle 1 + Angle 2 - Angle 3 = 107

Answer:
[tex]\frac{27}{2}[/tex]
Step-by-step explanation:
Okay, first whenever you divide a fraction, you're going to want to multiply by the reciprocal. The reciprocal or the inverse in this case is [tex]\frac{3}{2}[/tex].
Multiply 9 with the integer. Also, remember that numbers that aren't fractions like 9 can be written as a fraction with a 1 in the denominator. 9 = [tex]\frac{9}{1}[/tex]. So,
[tex]\frac{9}{1}[/tex] × [tex]\frac{3} {2}[/tex]. Multiply across. The numerators together (9 with 3) and the denominators together (2 with 1).
9 × 3 = 27 and 1 × 2 = 2. As a fraction the answer will come out to be [tex]\frac{27}{2}[/tex].

Jess is thinking of a number. Eight less than six times the number is 64. Find the number.
Answer:
-32
Step-by-step explanation:
the expression would be n ( 8 - 6 ) = 64. first solve whats in the parentheses, which is -2. then multiply n by -2, which is -2n = 64. divide 64 by -2, which is -32. to check, multilpy -2 by -32, which is 64. therefore the number is -32.

1) A 60 cm length of wire is used to form a rectangle. The
width of the rectangle is 3 cm longer than the height. Not all
the wire is used.
Find the range of values for the shortest side.
Answer:
Step-by-step explanation:
here's a somewhat answer, and how to solve it
lets assume that all "60 cm wire is used to make a rectangle"
h = a
w = a + 3
the perimeter of the rectangle is
a + a + a + 3 + a + 3 = 60
4a = 54
a = 13.5
-------------------------------
height = 13.5
width = 16.5
BUT, the problem says "not all the wired is used"
how much? 59? 58? 57.... the lowest value for the shortes side is 1
h = 1
w = 1 + 3 = 4
perimeter : 1 +4 + 4 + 1 = 6cm
