If you factor the equation you can see what the solutions are. Two factor a quadratic of the form ax^2+bx+c, find two values which satisfy two conditions...

jk=ac=-15 and j+k=b=-2 so j and k must be -5 and 3 so the factors are:

(x-5)(x+3)

So the other solution is x=5

What is the effect on the graph of f(2) g(2) =} - 1? 1 when it is transformed to g(x)=1/x -7

777dan777 [17]

The effect on the graph of f(x)= 1/x when it is transformed to g(x)= 1/x-7 is C. The graph of f(x) is shifted 7 units down.

<h3>What is a graph?</h3>

A graph is a diagram showing the relation between variable quantities, each measured along with one of a pair of axes at right angles.

In this case, the effect on the graph of f(x)= 1/x when it is transformed to g(x)= 1/x-7 is that the graph of f(x) is shifted 7 units down.

The missing options include:

A. The graph of f(x) is shifted 7 units up

B. The graph of f(x) is shifted 7 units to the left

C. The graph of f(x) is shifted 7 units down

D. The graph of f(x) is shifted 7 units to the right.

Using the Pythagorean Theorem, find the length of a leg of a right triangle if the other leg is 8 feet long and the hypotenuse i

iren [92.7K]

The <span>Pythagorean Theorem tells us that $a^{2}+b^{2}=c^{2}$ where c is the </span><span>hypotenuse and a and b are the other two sides. To solve for one of the shorter sides we need to rearrange:

$b=\sqrt{c^{2}-a^{2}}$

We can then substitute known values, and solve:
</span> $b=\sqrt{10^{2}-8^{2}}$
$b=\sqrt{100-64}$
$b=\sqrt{36}$
$b=6 feet$

If ABC and GEF are congruent, the value of x is and the value of y is

luda_lava [24]

Answer:

The value of x is 10, and the value of y is 6

Step-by-step explanation:

ABC and GEF are congruent

x - 8 = 2

x = 10

x - y = 4

10 - y = 4

y = 10 - 4

y = 6

Answer

x = 10, y = 6
