How many solutions does the system have? { y = − 7 x + 8 y = − 7 x − 8 ⎩ ⎪ ⎪ ⎨ ⎪ ⎪ ⎧ y=−7x+8 y=−7x−8
The system of equations y =−7x + 8 and y = −7x − 8 have no solution
How many solutions does the system have?From the question, we have the following parameters that can be used in our computation:
y =−7x + 8
y = −7x − 8
Subtracting the two equations
We have
y - y = -7x + 7x + 8 + 8
When the like terms are evaluated, we have
0 = 16
The above equation is false
This means that the equation has no solution

i will mark brainliest !! write an exponential function for the set of points. picture is below
Answer:
[tex]y = 6(2^{x} )[/tex]
Step-by-step explanation:
Let
[tex]y = kb^{x}[/tex]
When x = 0, y = 6. So, [tex]6 = kb^{0}[/tex] = k(1 ) = k
Since k = 6 we have [tex]y = 6b^{x}[/tex]
When x = 1, y = 12.
So [tex]12 = 6b^{1} = 6b[/tex]
b = 2
Therefore, the exponential function is [tex]y = 6(2^{x} )[/tex]
What is the range of the function f(x)= 2 + 4 when the domain is {-2, 0, 3}?
A {4.25, 5, 12}
B. {0, 4, 10}
C. {4.25, 4, 12}
D. All Real Numbers
The domain is the possible input values "x" .. in this case [-4, -2, 0, 2, 4]
The range are the possible output values of f(x)
We need to solve f(x) = 3.2x for each value in our domain
f(-4) = 3.2(-4) = -12.8
f(-2) = 3.2(-2) = -6.4
f(0) = 3.2(0) = 0
f(2) = 3.2(2) = 6.4
f(4) = 3.2(4) = 12.8

Help please!!! Find x and Y
Answer:
x = 40
y = 15
Step-by-step explanation:
Given is an equilateral triangle.
Measure of each angle of an equilateral triangle is 60°.
Therefore,
(x + 20)° = 60°
x + 20 = 60
x = 60 - 20
x = 40
4y = 60
y = 60/4

-360 divided by -40 ?
Answer: 9
Step-by-step explanation:
The required -360 divided by -40 is equal to 9. The negative signs cancel out when dividing two negative numbers, resulting in a positive result.
When dividing two negative numbers, it's helpful to keep in mind the following rule:
The division of two negatives yields a positive result.
Now, let's perform the division:
-360 ÷ -40
Since both numbers are negative, we know the result will be positive.
Divide the absolute values of the numbers.
|-360| ÷ |-40| = 360 ÷ 40 = 9
Apply the rule for the division of two negatives.
Since both numbers are negative, the result will be positive:
-360 ÷ -40 = 9
Therefore, -360 divided by -40 is equal to 9.

If a figure is dilated by a factor of 1.5, the area of the figure will change by a factor of
Answer:
The figure will change by a factor of 2.25.
Step-by-step explanation:
When the lengths (1-dimensional) change by a factor 1.5 (the definition of dilating a figure), the area (2-dimensional) will change by a factor 1.5 to the power of the quotient of the values of the dimensions, which is 2/1 = 2. So the area will change by a factor of 1.5^2 = 2.25.

10 Determine the area of the figure. 9 cm 6 cm 12 cm
Answer:
Area= 648
Step-by-step explanation:
Area formula: L times W times H
9 times 6 times 12 :)
When the length, width, and the height is given so the area of the figure is considered to be 648.
Calculation of an area:Since the length is 9cm
The width be 6 cm
And, the height is 12 cm
So, the area be like
= (9) (6) (12)
= 648
Hence, When the length, width, and the height is given so the area of the figure is considered to be 648.

The explicit formula for the geometric progression is f ( x ) = 3 ( 4 )ˣ⁻¹
What is Geometric Progression?A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.
The nth term of a GP is aₙ = arⁿ⁻¹
The general form of a GP is a, ar, ar2, ar3 and so on
Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )
Given data ,
Let the geometric progression be represented as A
Now , the value of A is
f ( x + 1 ) = 4 f ( x )
where the second term is a₂ = 12
Now , the explicit formula is given by
f ( x ) = 3 ( 4 )ˣ⁻¹
when x = 2
f ( 2 ) = 3 ( 4 )²⁻¹
f ( 2 ) = 3 ( 4 )
f ( 2 ) = 12
Hence , the GP is f ( x ) = 3 ( 4 )ˣ⁻¹
