quadratic formula
equivalent Find the number that makes the ratio equivalent to 1:7. 4:
Answer:
28
Step-by-step explanation:
Ratios are like fractions. Since you're finding an equivalent ratio, u can set them up like equivalent fractions and put an x where the missing number would go:
[tex]\frac{1}{7} = \frac{4}{x}[/tex]
You can either cross multiply and then solve for x, but it's easier to just think about it. The fractions are equivalent, right? So for them to be the same you'd have to do to the bottom what u do to the top.
To get from 1 to 4, you multiply by 4. By that logic, to get from 7 to x you'd have to multiply by 4 as well. Therefore x = 7x4, which is 28.
So x = 28
i need help asapp i’ll be giving a brainliest to the person with the correct answer
Are they correct? Is that the question? Well, the first one is correct because Slope (m) = -6/1 =-6
Equation of the line:
y = -6x + 15
When x=0, y = 15
When y=0, x = 2.5
and the other one:
Is incorrect and the correct answer is A because y= 7.5x -2. 7.5 is positive, the slope, and -2 is the y-intercept. Its negative.

18. A juice recipe calls for 3 1/2 cups
of sugar and will serve 60 people.
How much sugar would you need
if you reduced the recipe to serve
only 48 people?
A 4 2/3c B 3 1/2c C 2 4/5 c D 2 1/2c
Answer:
C. 2 [tex]\frac{4}{5}[/tex] cups
Step-by-step explanation:
We want 3.5 (3 1/2) cups of sugar that serves 60 people to serve 48 people instead. So we use proportions. Set it up:
[tex]\frac{x}{3.5} = \frac{48}{60}[/tex]
60x = 168 (48 x 3.5)
/60 /60
x = 2.8 cups of sugar serves 48 people.
Change 2.8 into fractions: 2 [tex]\frac{4}{5}[/tex]

Muffins cost $3.00 per dozen.
Andre says, “I have $2.00, so I can afford 8 muffins.”
Elena says, “I want to get 16 muffins, so I’ll need to pay $4.00
D you agree with either of them? Explain your reasoning.
Answer:
I agree with both of them
Step-by-step explanation:
A dozen is 12 muffins. Therefore, you pay $3.00 for 12 muffins.
We know that you pay $3.00 for 12 muffins we need to find out how much EACH muffin cost. For that we need to divide $3.00 by 12 which is 0.25.
Now we need to know how much it will cost us for 16 muffins. We use our equation 16*0.25 which is 4. Elena said she will pay 4 so she is right.
Andre said he will buy 8 muffins so we use our equation again 8*0.25 which is 2. He said he will pay 2 so he is right.

Answer:

Step-by-step explanation:
Given
[tex](x_1,y_1) = (0,3)[/tex]
[tex](x_2,y_2) = (4,7203)[/tex]
Required
Determine an exponential function
Substitute 0 for x and 3 for y in [tex]y=ab^x[/tex]
[tex]3 = ab^0[/tex]
[tex]3 = a*1[/tex]
[tex]3 = a[/tex]
[tex]a = 3[/tex]
Substitute 4 for x and 7203 for y in [tex]y=ab^x[/tex]
[tex]7203= ab^4[/tex]
Substitute 3 for a
[tex]7203= 3*b^4[/tex]
Divide both sides by 3
[tex]2401= b^4[/tex]
Take 4th root of both sides
[tex]\sqrt[4]{2401} = b[/tex]
[tex]7 = b[/tex]
[tex]b = 7[/tex]
Substitute 3 for a and 7 for b in [tex]y=ab^x[/tex]

Answer:
1) Lowest temperature = -5.5 (Wednesday)
2) a. -62 is less than (colder than) -55 so the average temperature on Mars is warmer.
b. -62 < -55
3) No. -14 means that the number is 14 less than zero. -21 means that the number is 21 less than zero. Also, if you plot these numbers on a number line, -21 will be further to the left than -14. The further to the left a number is, the less it is. So, -21 is less than -14 and Anchorage is colder than Minneapolis.
