Is (-1,4) a solution to the graph of
y= 3x + 7?
EXPLAIN WHY OR WHY NOT
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.

A child flies a kite at a height of 90 ft, the wind carrying the kite horizontally away from the child at a rate of 30 ft/sec. How fast must the child let out the string when the kite is 150 ft away from the child?
By Pythagorean theorem and differential calculus, the child must let out the string when the kite is 150 feet away at a rate of change of 25.725 feet per second.
How to determine the rate of change of the string
The geometric representation of this question is based on the Pythagorean theorem:
l² = x² + y² (1)
Where:
x - Horizontal distance of the kite from the kite, in feet.y - Height of the kine, in feet.l - Length of the string, in feet.The rate of change of the length of the string is obtained by differential calculus:
[tex]2 \cdot l \cdot \dot l = 2\cdot x \cdot \dot x[/tex]
[tex]\dot l = \frac{x\cdot \dot x}{l}[/tex]
[tex]\dot l = \frac{x\cdot \dot x}{\sqrt{x^{2}+y^{2}}}[/tex] (2)
If we know that x = 150 ft, y = 90 ft and [tex]\dot x = 30\,\frac{ft}{s}[/tex], then the rate of change of the length of the string is:
[tex]\dot l = \frac{(150\,ft) \cdot \left(30 \,\frac{ft}{s} \right)}{\sqrt{(150\,ft)^{2}+(90\,ft)^{2}}}[/tex]
[tex]\dot l \approx 25.725\,\frac{ft}{s}[/tex]
By Pythagorean theorem and differential calculus, the child must let out the string when the kite is 150 feet away at a rate of change of 25.725 feet per second.

Answer:
250.5 - 35 m = 300 - 35.25 m
Step-by-step explanation:
n ⇒ number of months it will take for both accounts to have the same amount of money
∴ the equation should be: 250.5 - 35 m = 300 - 45.25 m
⇒ 250.5 - 300 = -45.25m + 35m
⇒ -49.5 = -10 · 25m

A shopkeeper bought a fan for rupees 840 at what price should he sell it to make a profit of 10% If he makes a loss of 5% by selling at what is the selling price
Answer with Step-by-step explanation:
10% of 840 can be found by multiplying 840 by 0.10 (or dividing 840 by 10)
10% of 840 = 84
To make a profit of 84 he needs to sell at 840 + 84 = 924 rs
5% of 840 can be found by multiplying 840 by 0.05 (or dividing 840 by 20)
5% of 840 = 42
To make a loss of 42 he needs to sell at 840 - 42 = 798 rs

How do I calculate a angle that is not named?
please explain and give answer
Angle 1=87°
Angle 2=88°
angle 1+2= 177
Step-by-step explanation:
I believe thsi should be right,
So angle 1 and 87° are the same because of some rule, then the angle above 2 would be 92 because of the same rule and its a straight line so 180-92=88 making angle 2, 88. When you add those it would be 177. Try that
Tell whether the sequence is arithmetic, if it is, write a function rule to represent it.

Identify the slope-intercept form and the graph of the line described by the equation 3x − 3y = 15.
Answer:
The slope-intercept form is y=x-5
The graph is in the picture below
Step-by-step explanation:
To find the slope-intercept you need to move y all by itself:
y=mx+b
subtract 3x on both sides:
-3y=-3x+15
Divide by -3 on both sides:
y=x-5
Hope this helps!
(Why I took two pictures is because to show you that the line is the same even with it being slop-intercept form)

Jason multiplied 1.5 by a power of ten and got 150. What power of ten did he multiply by?
Answer:
Jason multiplied 1.5 by the whole number 10.
Step-by-step explanation:
As opposed to multiplying 1.5 by the tenth power, in which Jason would've received 57.66503..., he multiplied 1.5 by 10 units, resulting in a product of 150.
Hope this helps!
The power of ten did he multiply by 2.
Given that;
Jason multiplied 1.5 by a power of ten and got 150.
Let us assume that;
The value of power = x
Hence it can be written as,
1.5 × 10ˣ = 150
Divide both sides by 1.5;
10ˣ = 150/1.5
10ˣ = 100
It can be written as,
10ˣ = 10²
This gives,
x = 2
Therefore, the value of power is 2.

Under her cell phone plan, Grace pays a flat cost of $70 per month and $4 per gigabyte. She wants to keep her bill at $74.40 per month. Write and solve an equation which can be used to determine xx, the number of gigabytes of data Grace can use while staying within her budget. i don´t understand how to set up the problem.
The equation of the cell phone plan is y = 70 + 4x and the number of gigabyte is 1.10
How to determine the equation?The given parameters are:
Flat = $70 per month
Rate = $4 per gigabyte
Let the number of gigabyte be x, and the total cost be y.
So, we have:
y = Flat + Rate * x
So, we have:
y = 70 + 4x
When the bill is $74.40, we have:
74.40 = 70 + 4x
Subtract 70 from both sides
4x = 4.40
Divide both sides by 4
x = 1.10
Hence, the equation is y = 70 + 4x and the number of gigabyte is 1.10
