If (a, –5) is a solution to the equation 3a = –2b – 7, what is a?

Mathematics

Answer:

d)  1

Step-by-step explanation:

3a = –2b – 7

We have the point (a, -5) so b = -5

Substituting in

3a = -2(-5) -7

3a = 10-7

3a = 3

Divide each side by 3

3a/3 = 3/3

a =1

How many bricks are left over if you place 213,854 bricks in groups of 10,000?
Monica [59]
This is dividing 213854 by 100000 but instead of giving a decimal you want to give a remainder.

213854/100000 is 2.13854. So you have 2 units, which is 200000.
Subtract 200000 from 213854 and you're left with 13854 bricks that remain.

Write in slope-intercept form the equation of the line passing through the given point and perpendicular to the given line.
Ksivusya [100]

Answer:

y = x + 1

Step-by-step explanation:

First you find the slope of the first line using the rise over run method. Here you can see that the line goes up 1 and to the right one in order to reach the next point making the slope 1x or just x. Then you need to make it so that the line intercepts the point by changing the y intercept to 1 making the equation y = x + 1.

I hope this helped!!

Zoe went on a shopping trip to Fairfax. She purchased a barbecue grill originally priced at $600 but discounted 50%. If sales ta
sergey [27]

Answer:

The total cost is $345

Step-by-step explanation:

Zoe  purchased a barbecue grill originally priced at $600

Discount % = 50%

So, cost after discount = 600-50\%(600)

Cost after discount =300

Sales tax in Fairfax is 15%

So, cost including tax = 300+0.15(300)

Cost including tax = 345

Hence The total cost is $345

The graphs below have the same shape. what is the equation o the red graph?
maw [93]

So the equation of the red graph is already given to us: f(x) = x^2. I assume you meant the blue graph?

We can use the vertex form: y = a(x - h)^2+ k, where (h,k) is the vertex. (We can ignore a because a is 1 for this graph.) Remember that the vertex is the maximum or minimum of a parabola and the point that the line of symmetry passes through. For f(x) the vertex is (0,0).

The vertex for g(x) is at (-4, -2) on the coordinate plane. (4 left, 2 down)

Plug into the vertex form:

y = (x - (-4))^2 -2

The double negative becomes a positive, and then you're done:

y = (x + 4)^2-2

Is A number decreased by three squared a nonlinear or linear
Harlamova29_29 [7]
Linear. because when you decrease 10 by 3 squared which is 9 you go to one and then when you decrease one by 9 you get negative 8. :)
