Answer:

x = - 3

y = 4

Step-by-step explanation:

x + 3y = 9

- 3x - 3y = - 3

x + 3y = 9

_____________

- 3x + x = 9 - 3

- 2x = 6

2x = - 6

x = - 3

The following system has no solutions: y=4x+5 and y=2x+3 True False

False, both lines are oblique (diagonal) so they meet at some point on a graph. They can only have no solutions if the lines are parallel/have the same slope.

Please help me, I’m Dumb

vova2212 [387]

Answer: OPTION C

Step-by-step explanation:

To solve the exercise shown in the image attached, you need to subtract the functions f(x) and g(x).

Keeping the above on mind, you have:

$(f-g)(x)=2x^{2}+2-(x^{2}-1)$

You must distribute the negative sign and then you must add the like terms, therefore, you obtain:

$(f-g)(x)=2x^{2}+2-x^{2}+1\\(f-g)(x)=x^{2} +3$

Sharon is painting her house. she needs 5 gallons of brown paint for every 7 gallons of white paint. How many gallons of white

Igoryamba

Answer:

19.6

Step-by-step explanation:

The ratio of brown paint to white paint is, 5:7 or $\frac{5}{7}$ so if he bought 14 gallons of white paint we need to figure out:

$\frac{5}{7} =\frac{14}{x}$

which we can as it only has one unknown:

5x=14×7

5x=98

x=19.6

So the answer is 19.6

How do you write mixed numbers or fractions as decimals?

aksik [14]

To write fractions as decimals divide the numerator by the denominator, for example 3/4 3 divided by 4 equals 0.75 so 3/4 as a decimal is 0.75. If you want to do that with a mixed number, 3 3/4 3 divided by 4 equals 0.75 then add the 3 so 3 3/4 is equal to 3.75.
