What goes on the lines I don’t understand the problem

Mathematics
1 answer:
Elis [28]3 years ago
3 0

Answer:

Step-by-step explanation:

a). Let the number of spoons = x

And number of forks = y

Total number of spoons and forks bought by Perry = 10

x + y = 10 --------(1)

Cost of one spoon = $5

Cost of one fork = $3

Therefore, total cost of x spoons and y forks = $(5x + 3y)

5x + 3y = 42 -------(2)

b). Now we can convert these equations into the slope-intercept form.

x + y = 10 ⇒ y = -x + 10

Table for input output values,

x        2         4          6          

y        8         6          4                

5x + 3y = 42

3y = -5x + 42

y = -\frac{5}{3}x+14

x        0           3          6        

y       14           9          4                  

Point of intersection of these lines will be (6, 4).

VMariaS [17]
D=dimes
q=quarters

d + q = 20
.10d + .25q = 3.05

d=-q + 20

.10(-q + 20) +.25q = 3.05
-.10q + 2 + .25 = 3.05
.15q + 2 = 3.05
.15q + 2 - 2 = 3.05 - 2
.15q = 1.05
.15q/.15 = 1.05/.15
q = 7

d + 7 = 20
d + 7 - 7 = 20 - 7
d = 13

Sally has 7 quarters and 13 dimes.
Hope this helps!

Find the value of f(g(-2))<br> f(x) =-2x+14<br> g(x)=3x^2+6x-2
Rzqust [24]

Answer:

-2

Step-by-step explanation:

f[g(x)

=f(3x^2+6x-2)

=2 (3x^2+6x-2)+14

=6x^2+12x-4+14

=6x^2+12x+10

f[g(-2)]=6 (-2)^2+12×(-2)+10

=12- 24+10

=-2
