Pls help Zoey is trying to write an equation in slope intercept form. She knows slope intercept form is y=mx+b. She is given the slope is 3 and the y intercept is 10. When she plugs it in she gets 10=3x+b. What mistake did zoey make and how can she fix it?

Answers

Answer 1

Answer:

Answer:

the mistake that zoey had made while writing the equation was putting the y-intercept in the wrong place.in the slope intercept from the equation is y=mx+b.y is the product or the line, m is the slope, b is the y-intercept, the actual equation should be y=3x+10,instead what zoey had which was 10=3x+b. she guessd by pairing the y-intercept with y instead of b.

Given vectors a and b, which operation does the green vector show? options: 2a + ba - b
a + b
ab

Answers

If we treat b sliding vector, then head of green vector coincide with tail of b vector. So,in this Senior a is acting as a resultant vector. To get this resultant vector a, the green vector must be a-b.

At the bank,Brent exchanges $50 in bills for 50 one dollar coins.The total mass of the coins is 405 grams.Estimate the mass of 1 one dollar coin

Answers

Data:

$50 dollars in bills → 50 coins of one dollar

Estimate the mass of one dollar coin
Solving:

50 coins → 405 grams
1 coin → x

The rule of three

50*x = 405*1
50x = 405
$x = (405)/(50)$
$x = 8,1$
We have:

$\boxed{x \approx 8grams/coin}$

405/50=8.1grams
if asked to simplify the answer would be 8 grams per coin

Manuel buys 7.9 pounds of strawberries. Each pound costs $3.89. Which expression gives the best estimate of the cost of the strawberries?(8)($4)(7)($4)(8)($3)(7)($3)

Answers

The options you gave are extremely confusing, but if you round 7.9 it is 8, and if you round $3.89 it is $4. Therefore, the best estimate would be 8•$4, or $32

Answer: Its {8}{4$}

Step-by-step explanation:

because 7.9 rounds up to 8 and 3.89 rounds up to four.
