How do you find a value of x so that f(x) = 7?

Mathematics
1 answer:
DiKsa [7]3 years ago
5 0

Answer:

When f(x) = 7, x is equal to 5.

Step-by-step explanation:

When looking at this graph, we are looking for where the line hits a point where y is equal to 7. That's because f(x) is essentially the same thing as y.

The point in which the graph hits y = 7 is (5, 7). This means the x value we need is 5.

One side of a triangle is half the longest side. The third side is
Illusion [34]

Answer:

The length of the sides are 9 units, 18 units and 11 units

Step-by-step explanation:

Let

x ----> one side of the triangle

y ----> the longest side of the triangle

z ----> the third side of the triangle

we know that

The perimeter of triangle is equal to

P=x+y+z

we have

P=38\ units

so

38=x+y+z ----> equation A

x=\frac{y}{2} -----> equation B

z=y-7 ----> equation C

substitute equation B and equation C in equation A

38=\frac{y}{2}+y+(y-7)

solve for y

38=\frac{5}{2}y-7

\frac{5}{2}y=38+7

\frac{5}{2}y=45

y=45(2)/5

y=18\ units

<em>Find the value of x</em>

x=\frac{y}{2} ---> x=\frac{18}{2}=9\ units

<em>Find the value of z</em>

z=y-7 ----> z=18-7=11\ units

therefore

The length of the sides are 9 units, 18 units and 11 units

The total number of victories for a football team exceeds the number of defeats by 4, with no draws. Knowing that if 44 jojos, h
Leno4ka [110]

Answer: 24

Step-by-step explanation:

Let the number of defeats be represented by x.

Since the total number of victories exceeds the number of defeats by 4, then the number of victories will be:

= x + 4

We then add the number of victories and losses together and equate them to 44. This will be:

x + x + 4 = 44

2x + 4 = 44

2x = 44 - 4

2x = 40

x = 40/2

x = 20

Therefore number of victories will be:

= x + 4

= 20 + 4

= 24
