solve the simultaneous linear equations by using the elimination method
a - b = -3
3a - 4b = -5
Answer:
3a -3b= -9
3a - 4b = -5
-------------------
b=-4
4a- 4b= -12
3a - 4b = -5
-------------------
a = -7
Solve for j.
j − –95 = 822
j =
Answer:
j = 727
Step-by-step explanation:
j - (-95) = 822j + 95 = 822j = 822 - 95j = 727Ava bought 2 sandwiches for a total of $5.25 , a bowl of soup for $3.00, and a bag of chips for 1.25. How much change did she get back if she paid with a $20.00 bill?

Martin had 7 pounds of grapes left, and he gave away 2
5
of them. Explain how to use compatible numbers to estimate the amount of grapes he gave away.
#Nova
Answer: 2/5 is closer 1/2. and it is easy to find half of 7 mentally. Half of 7 is 3.5, so Martin gave away about 3.5 pounds away.
Is this a function?
Answer:
No, because if you do the vertical line test, the line will hit that two times, Therefore it is not a function.

What is the value of x
Answer:
12Step-by-step explanation:
We know the hypotenuse and legs of 45° right triangle have ratio:
h ÷ l = √2 ÷ 1Substitute given values and find x:
x ÷ 6√2 = √2x = 6√2 × √2 x = 12Write the linear equation in slope-intercept form and simplify.
–4x + 13y = 7
[tex]\\ \sf\longmapsto -4x+13y=7[/tex]
[tex]\\ \sf\longmapsto 13y=4x+7[/tex]
[tex]\\ \sf\longmapsto y=\dfrac{4x+7}{13}[/tex]
[tex]\\ \sf\longmapsto y=\dfrac{4}{13}x+\dfrac{7}{13}[/tex]

Find the distance between the points (
–
9.5,4.1) and (2.7,4.1).
Answer:
Step-by-step explanation:
Distance formula: [tex]d=\sqrt{(y_{2}-y_{1})^{2}+(x_{2}-x_{1})^{2}}[/tex]
[tex]d=\sqrt{(4.1-4.1)^{2}+(2.7-9.5)^{2}}=\sqrt{(-6.8)^{2}} = 6.8[/tex]
Note that distance is always positive

Claim: Fewer than 95% of adults have a cell phone. In a reputable poll of 1170 adults, 90% said that they have a cell phone. Find the value of the test statistic.
Answer:
From the information given, it is found that the value of the test statistic is z = -11.97.
At the null hypothesis, it is tested if the proportion is of at least 95%, that is:
At the alternative hypothesis, it is tested if the proportion is of less than 95%< that is:
The test statistic is given by:
In which:
is the sample proportion.
p is the value tested at the null hypothesis.
n is the sample size.
In this problem, we have that the parameters are:
.
Thus, the value of the test statistic is:
The value of the test statistic is z = -11.97.

Hello there, below here is an attached file of the particular question I have. Thank you so much for coming here to answer! I appreciate you, and I hope have a good day or night!
Answer:
a: 0
b: 1,3
c: 2
Step-by-step explanation:
a: 4 is the y intercept meaning 0 is the number of seconds when the ball is 4 feet in the air
b: to easily find this, we can graph.
1st screenshot is for B.
We see that y=52 intersects twice with the graph, meaning the ball was at 52 feet twice. the times are 1 second and 3 seconds
a: we graph again, but with y=68 we see that it only intersects once. at x=2.

Suppose that a piano costs $6,000 and loses 15% of its value each year. The table below shows the value, v, of a piano after, t, years.
Part A: Write an equation to find the value of the piano, v, after t years.
Part B: What will be the value of the piano after 16 years? Round your answer to the nearest hundredth.
v(value)=6000-0.15t(years)

table value equation for y=2x + 4
Answer:
below
Step-by-step explanation:
All we need to do is substitute the x values given in the table to find each value of y thats blank.
When x = -1,
y = 2(-1) + 4
y = -2 + 4
y = 2
When x = 1,
y = 2(1) + 4
y = 2 + 4
y = 6
Whe x = 2,
y = 2(2) + 4
y = 4 + 4
y = 8
